Nsuku zonke, abathengi bathembela ezintweni zokugqoka okumele zimelane nengcindezi enkulu yemishini, kusukela kubhaka othwala izincwadi ezisindayo kuya ezintanjeni zokuphepha ezivikela abasebenzi ezindaweni eziphakeme. Lapho indwangu yehluleka ngaphansi kwengcindezi, imiphumela isukela ekungakhathazekini okuncane kuya ezingozini ezinkulu zokuphepha, futhi abakhiqizi bathwala izindleko zezimali nokulahlekelwa idumela ngenxa yalokhu kwehluleka. Cabanga ngentambo yokuqwala izintaba ephukayo ngesikhathi sokukhuphuka noma ingubo yokuhlinza edabukayo ngesikhathi senqubo ebalulekile; izenzakalo ezinjalo zigcizelela ukuthi kungani ukukala amandla okudonsa kwendwangu kungesiyo nje ukuhlola ikhwalithi kodwa kuyimfuneko eyisisekelo yokuphepha komkhiqizo nokusebenza kahle. Ngaphandle kokuphepha, amandla okudonsa kwendwangu athinta ngqo ukwaneliseka kwamakhasimende, ukwethembeka komkhiqizo, kanye nenani lesikhathi eside somkhiqizo, njengoba abathengi bashiye ngokushesha imikhiqizo ehluleka ngaphambi kwesikhathi. Ukuhlola amandla okudonsa ngaphansi kwezimo ezijwayelekile kuvumela abakhiqizi ukuthi babikezele ukuthi izinto zizoziphatha kanjani ekusetshenzisweni kwangempela, kuqinisekiswa ukuthi izindwangu ezihlangabezana nezimfuneko eziqinile kuphela ezifinyelela emakethe. Ezimbonini ezinjengezimpahla zokuvikela, izingaphakathi zezimoto, nemishini yangaphandle, ukuhlola amandla okudonsa ngokungaguquki kuwumgogodla wokuthuthukiswa komkhiqizo ngokuzibophezela nokuthobela imithetho.

Ngaphambi kokungena ezinhlelweni zokuhlola, kubalulekile ukwehlukanisa amagama amabili avame ukudidaniswa: ukucindezeleka kokudonsa (tensile stress) namandla okudonsa (tensile strength). Ukucindezeleka kokudonsa kubhekisela emandleni asetshenziswa endaweni ngayinye yendawo ephambanayo yendwangu, ngokuvamile kukalwa ngama-megapascal (MPa) noma ngamaphawundi ngesikwele-intshi (psi), futhi kuchaza ukumelana kwangaphakathi kwento ngenkathi idonswa ihlukaniswe. Amandla okudonsa, ngakolunye uhlangothi, awukucindezeleka okukhulu kakhulu into engakumelana nakho ngaphambi kokuba iphuke, emele umkhawulo wokugcina wekhono lendwangu lokuthwala umthwalo ngaphansi kokudonsa. Ngamazwi alula, ukucindezeleka kokudonsa kuchaza ukuthi kwenzekani entweni ngesikhathi sokuhlolwa, kuyilapho amandla okudonsa echaza iphuzu elibucayi lapho ukwehluleka kwenzeka khona. Konjiniyela bezindwangu, ukuqonda lo mehluko kubalulekile ngoba indwangu ingase ibhekane namazinga ahlukahlukene okucindezeleka kokudonsa ngesikhathi sokusetshenziswa okuvamile, kodwa kuphela lapho lokho kucindezeleka kudlula amandla okudonsa kwento lapho ukwehluleka okuyinhlekelele kwenzeka khona. Ithebula elingezansi licacisa umehluko phakathi kwale mibono emibili ehlobene kodwa ehlukile.

Uma isampula yendwangu ibhekana namandla okudonsa, kwenzeka uchungechunge oluyinkimbinkimbi lwezehlakalo zomshini ngaphambi kokuba into igcine iphukile. Ekuqaleni, imicu engaphakathi kwendwangu iyaqondana futhi ihambisane nendlela amandla asetshenziswa ngayo, into eyaziwa ngokuthi i-crimp interchange, evumela indwangu ukuthi yeluleke ngokumelana namandla amancane. Njengoba amandla ekhula, imicu iqala ukushibilikela enye kwenye ngenqubo ebizwa ngokuthi i-yarn slippage, ikakhulukazi ezigxotsheni ezilukwe ngokukhululekile, okuholela ekuguqukeni okwengeziwe nokuncipha kokuqina kwendwangu. Ekugcineni, imicu ngayinye ifinyelela ezingeni layo lokugqashuka, futhi ukugqashuka kwemicu kwenzeka, kusakazeka ngokushesha kuyo yonke isampula kuze kube yilapho kuqhekeka ngokuphelele. Ukuqonda lezi zinqubo eziyisisekelo kubalulekile ngoba zichaza ukuthi kungani ukuhlolwa kwamandla okudonsa kwendwangu kungenziwa ngezindlela ezijwayelekile zokuhlola izinto eziklanyelwe izinsimbi noma amapulasitiki aqinile. Izindwangu ziyagwedluka, ziyaguquguquka, futhi azilingani, okusho ukuthi izakhiwo zazo ziyahluka kuye ngendlela amandla asetshenziswa ngayo, futhi zidinga imishini ekhethekile ekwazi ukuphatha izampula ezintekenteke ngaphandle kokudala umonakalo wokucindezela. Umshini oqinile wokuhlola amandla okudonsa wendwangu kumele uhlanganise izici ezinjengezibambo zomoya noma zemishini ezisabalalisa amandla ngokulinganayo, izilinganisi ezinembile ezithola izinguquko ezincane ekudonseni, kanye nama-extensometer noma ukulandelela ukugudluka kwe-crosshead ukuze kuqoshwe ukweluleka ngokunembile. Lolu lwazi lwesayensi lwakha isisekelo sezindinganiso zamazwe ngamazwe zokuhlola ezifana ne-ISO 13934 ne-ASTM D5034, ezichaza ubukhulu bezampula obunembile, izindlela zokubamba, nezivinini zokuhlola ukuze kuqinisekiswe imiphumela ephindaphindekayo nokuqhathaniseka ezilabhorethini emhlabeni wonke.

Isakhiwo sokwakheka kwendwangu sidlala indima enkulu ekunqumeni amandla ayo okudonsa, lapho izindwangu ezilukiwe, ezitshaliwe, nezingalukiwe ziziphatha ngendlela ehlukile lapho zidonswa. Izindwangu ezilukiwe, ezibonakala ngemicu ephambanayo neqondile, zivame ukubonisa amandla aphezulu okudonsa kuzona zombili izinhlangothi ngoba imicu ixhumene ngokuqinile futhi yabelana ngomthwalo kahle ezindaweni zokuhlangana. Izindwangu ezitshaliwe, ngokuphambene, zinesakhiwo esiyizingodo esivumela ukunwebeka nokuguquguquka okukhulu, kodwa lokhu kuza ngezindleko zamandla aphansi okudonsa uma kuqhathaniswa nezilukiwe ezinobunzima obufanayo nokuqukethwe kwemicu. Izindwangu ezingalukiwe, ezakhiwa ngokuhlanganisa imicu ngezindlela zemishini, zokushisa, noma zamakhemikhali, zibonisa ukwehluka okukhulu kakhulu kumandla okudonsa kuye ngokuthi imicu iqondiswe kanjani nokuthi ukuhlanganiswa kuminyene kangakanani, okwenza kube inselele ukuzihlola ngokungaguquki. Ubuningi bezindawo zokuhlangana endaweni ngayinye, ukuqina kokuluka, kanye nendlela yokuhlola uma kuqhathaniswa nemicu eqondile noma ephambanayo—konke lokhu kunomthelela esilinganisweni sokugcina samandla futhi kufanele kucatshangelwe ngokucophelela lapho kuhlelwa ukuhlolwa.

Izici zangaphakathi zemicu eyakha indwangu zibeka umkhawulo wethiyori wamandla okudonsa kwendwangu, ngoba amapholima ahlukene anezakhiwo zamangqamuzana ezihluke kakhulu ngakho-ke namandla okuthwala ahlukene. I-polyester enamandla aphezulu kanye nemicu ye-aramid inikeza amandla abalulekile, okwenza kube yizinto ezikhethwayo ezinhlelweni ezidinga kakhulu njengokuvikelwa kwezinhlamvu namabhande ezimboni, kuyilapho ukotini ne-viscose kunikeza amandla aphakathi nendawo ngokunwebeka okuphezulu. Isibalo semicu, esichaza ubukhulu bomugqa wemicu, naso sibaluleke kakhulu: imicu ejiyile ngokuvamile inikeza amandla amakhulu ngobubanzi obubodwa, kodwa futhi yandisa isisindo nokuqina kwendwangu. Ngaphezu kwalokho, izinga lokusonteka ngaphakathi kwemicu linomthelela ekutheni amandla emicu aguqulelwe kanjani abe amandla emicu, ngebanga lokusonteka okulungile elilinganisa amandla okubambana nokulimala kwemicu. Ukuhlanganiswa kwemicu ehlukene kunikeza amathuba okwakha izici zokudonsa, nakuba ukusebenzisana phakathi kwezinhlobo zemicu kungadala izindlela zokwehluleka eziyinkimbinkimbi ezidinga ukuchazwa ngokucophelela ngokuhlolwa kwamandla okudonsa.

Iziqondiso zangemva kokuluka zingashintsha kakhulu indlela indwangu eziphatha ngayo lapho idonswa, kwesinye isikhathi zithuthukise amandla, kwesinye isikhathi zehlise, futhi abahloli kumele babhekelele lezi zinguquko. Izinto zamakhemikhali zokuqeda njengezinto ezivimbela umlilo, ezinqanda amanzi, nezithambisayo zingathinta ukungqubuzana kwezintambo nokuhamba kwazo, okungenzeka kwehlise amandla okudonsa noma ngabe zithuthukisa ukusebenza kokusebenza. Izinqubo zemishini ezifana nokucindezela, ukuxubha, noma ukusanforiza zingashintsha ubujamo bendwangu nokusabalalisa kwengcindezi yangaphakathi, okuholela ezingushweni kuwo womabili amandla nokunwebeka lapho kephuka. Izimo zemvelo ngesikhathi sokuhlola nazo zinomthelela omkhulu, ngoba ukumuncwa komswakama, ukushintsha kwezinga lokushisa, namazinga omswakama kungathambisa izintambo futhi kushintshe indlela ezisabela ngayo ngokomzimba. Ngenxa yalesi sizathu, izindlela ezijwayelekile zokuhlola ziyala ukuthi izinhlobo zokuhlola zilungiswe endaweni elawulwayo, ngokuvamile ku-20°C kanye nomswakama ongu-65%, ngaphambi kokuqhubeka nokuhlola, ukuze kuqinisekiswe ukuthi izilinganiso zibonisa ukusebenza kwangempela kwento kunokuba kube yimiphumela yesikhashana yemvelo. Abakhiqizi abahluleka ukulawula lezi zinto eziguquguqukayo basengozini yokuthola idatha engathembekile eholela ezingqutsheni ezingezinhle zomkhiqizo nokwehluleka okungalindelekile emkhakheni.

Ukwethembeka kwanoma yisiphi isilinganiso samandla okudonsa kuncike ngokuphelele ekhwalithini nasekucopheleleni kwemishini yokuhlola esetshenziswayo, okwenza ukutshalwa kwezimali emishinini kube isu elibalulekile kunokuba nje kube yizindleko zokusebenza. Umshini wokuhlola amandla okudonsa wendwangu kumele uhlanganise i-load cell enokuhlukanisa okuphezulu ekwazi ukubamba lonke uhla lwamandla ngephutha elincane, ngoba ukufundwa okungaqondile kwamandla kuhumushela ngqo emandleni angalungile kanye nezinqumo ezingalungile zekhwalithi. Izinhlelo zokubamba zibalulekile ngokulinganayo, ngoba izinto zokubamba ezingaklanywanga kahle zingalimaza isampula lapho kuhlangana khona imihlathi, okuholela ekwehlulekeni ngaphambi kwesikhathi okungakhombisi amandla angempela wento futhi kwenze ukuhlolwa konke kungasebenzi. Ukulandelela okunembile kokunwebeka, noma ngokulinganisa ukunyakaza kwe-crosshead noma ngama-extensometer akhethekile, kubalulekile ekwakheni amajika okucindezeleka nokunwebeka anengqondo aveza ukuqina kwendwangu, indawo yokuguquka, kanye nezici zokumunca amandla. Lapho imishini yokuhlola ingakalibrishwa, ihlushwa ukuguga kwemishini, noma isebenzisa isofthiwe ephelelwe yisikhathi, imiphumela iba nzima: ukwehluleka kokulawula ikhwalithi kudlula kungabonwa, amaqembu okukhiqiza ahlukaniswa ngendlela engalungile, futhi ezimweni ezimbi kakhulu, imikhiqizo engaphephile ifinyelela kubathengi futhi ibangele ukubuyiswa okubizayo.

Ukucindezeleka kokudonsa (tensile stress) amandla angaphakathi atholwa yinto ngayinye yendawo lapho ibhekene nomthwalo wokudonsa, futhi kuyashintsha njengoba amandla asetshenziswayo ekhula ngesikhathi sokuhlolwa. Amandla okudonsa (tensile strength), ngakolunye uhlangothi, inani elithile lokucindezeleka lapho into yehluleka khona noma iphuka, limele umkhawulo wayo ophezulu wokuthwala umthwalo. Ukucindezeleka kokudonsa kukalwa ngokuqhubekayo ngesikhathi sokuhlolwa, kuyilapho amandla okudonsa eyisiphetho esibalulekile salokho kukalwa. Isibonelo, indwangu ingase ibhekane nokucindezeleka kokudonsa kwe-10 N/mm², 20 N/mm², nokunye, njengoba amandla ekhula, ize ifinyelele emandleni ayo okudonsa bese iyadabuka. Ukucindezeleka kokudonsa kuchaza isimo, kuyilapho amandla okudonsa echaza impahla yento.

Izindlela ezimbili ezisetshenziswa kakhulu emazweni ngamazwe zokulinganisa amandla okudabula kwendwangu yi-ISO 13934, okuyindinganiso yaseYurophu yokunquma amandla aphezulu nokunwebeka okuphezulu kusetshenziswa indlela yomucu, kanye ne-ASTM D5034, indinganiso yaseMelika esebenzisa indlela yokuhlola yokubamba. Zombili lezi zindinganiso zicacisa ubukhulu obunembile bezinhlaka, izinqubo zokubamba, isivinini sokuhlola, kanye nezimo zokulungisa nokuhlola indwangu. Lezi zindlela ezijwayelekile ziqinisekisa ukuthi imiphumela iyafana ezindaweni ezahlukene zokuhlola nasezimbonini zokukhiqiza. Abakhiqizi bavame ukudinga ukuhambisana nazo zombili lezi zindinganiso kuye ngezimakethe abazihlose kanye nezidingo zamakhasimende. Ukukhetha ithuluzi lokuhlola elihambisana nazo zombili i-ISO 13934 ne-ASTM D5034, njengalelo lakwaWangtebei, kunikeza ukuguquguquka okukhulu.

Ukukala amandla okudonsa kwendwangu, qala ulungise izinhlobo zendwangu ngokwezinga elihambisanayo, uzisike zibe ngobukhulu obucacisiwe bese uzibeka endaweni elawulwayo. Beka isampula phakathi kwezinsimbi zokubamba zomshini wokuhlola amandla okudonsa, uqinisekise ukuthi zihleleke kahle futhi ubude bokulinganisa bulungile. Setha isivinini sokuhlola, ngokuvamile 100 mm/min, bese uqala ukuhlola ukuze umshini udonse isampula ize iphuke. Isofthiwe yokuhlola irekhoda amandla aphezulu nokunwebeka, inikeze amandla okudonsa nolunye ulwazi lokuhlaziya.

Izinto eziningana zinganciphisa amandla okudonsa kwendwangu, okuhlanganisa ukulukwa okuxekethile noma okuvulekile, ukusetshenziswa kwezinhlobo zemicu ebuthakathaka, kanye nezinga eliphansi lezintambo. Izinqubo zokuqeda ngamakhemikhali, njengemithi ethile evimbela umlilo noma izithambisi, nazo zingonciphisa amandla emicu. Izimo zemvelo ezinjengomswakamo ophezulu nokuchayeka elangeni kungadala ukonakala ngokuhamba kwesikhathi, kunciphise amandla okudonsa. Amaphutha okukhiqiza, njengezindawo ezincanyana noma imicu eyonakele, adala amaphuzu abuthakathaka endaweni ethile anciphisa kakhulu amandla aphelele. Izinqumo ezingezinhle zokuklama mayelana nokuhlanganiswa kwemicu noma amazinga okusonta nazo zingabeka engcupheni amandla.

Ukuqhekeka kwendwangu eduze kwezibopho, into evame ukubizwa ngokuthi "ukugqekezeka kwemihlathi" noma "ukugqekezeka kokubamba," ngokuvamile kukhombisa ukuthi ingcindezi yokubamba iphezulu kakhulu, okwenza kube nokugxila kokucindezeleka endaweni yokubamba. Kungabuye kwenzeke uma isampula lingahambisani kahle ncamashi nesiqondisweni sokuhlola, okwenza kube nokulayisha okungalingani. Izindawo zokubamba ezonakele noma ezigqokile ezinamaphethelo abukhali zingasika indwangu emngceleni wokubamba. Ukusebenzisa izibopho zomoya ezinengcindezi elungisekayo nokuqinisekisa ukuthi isampula lihambisana kahle ngokuvamile kunciphisa le nkinga. Uma ukugqekezeka kwemihlathi kuqhubeka, kungadingeka usebenzise ukuthambisa okuthambile ezibophweni noma unciphise amandla okubamba.

Ukuze uthole idatha yamandla okudonsa ethembekile ngokwezibalo, izindinganiso eziningi, kuhlanganise ne-ISO 13934 ne-ASTM D5034, zincoma ukuhlola okungenani amasampula amahlanu ngendlela ngayinye kusuka kusethi ngalinye lamasampula. Ngenxa yokuthi izindwangu ziyizinto ezihlukahlukana ngokwemvelo, ukuhlola amasampula amaningi kukuvumela ukuba ubale isilinganiso, ukuchezuka okujwayelekile, kanye ne-coefficient yokuhlukahluka. Le ndlela yezibalo isiza ukubona ukuthi ukuhlukahluka kubangelwa umehluko ojwayelekile wezinto noma kukhombisa izinkinga zekhwalithi zangempela. Ezinhlelweni ezibalulekile noma lapho kubonwa ukuhlukahluka okuphezulu, ukuhlola amasampula amaningi kuvame ukuba ngokuhlakanipha. Ukubika amanani avamile nokuchezuka okujwayelekile kunikeza umbono ophelele kakhulu wekhwalithi yendwangu.

Yebo, imishini yokuhlola yezinto ezahlukene yanamuhla, kuhlanganise naleyo ehlinzekwa uWangtebei, iyimishini eguquguqukayo ekwazi ukuhlola izinto eziningi ezehlukene ngaphandle kwendwangu. Ngokushintsha ama-grips, ama-fixtures, nezilungiselelo zesofthiwe yokuhlola, uhlaka lomshini olufanayo kanye ne-load cell kungahlola amapulasitiki, irabha, izinsimbi, amafilimu, iphepha, nokunye okuningi. Lokhu kuguquguquka kwenza umshini wokuhlola wokudonsa we-universal ube utshalomali olubalulekile emalabhorethri asebenza ngezinhlobo eziningi zezinto. UWangtebei unikeza izinsiza ezengeziwe ezifana nezinhlobo ezahlukene zama-grips, ama-bend fixtures, nama-compression platens ukuze kwandiswe amandla omshini. Lokhu kuguquguquka kuvumela abakhiqizi ukuthi benze ukuhlola okuphelele kwezinto ngomshini owodwa, ongabizi kakhulu.

Ukusebenzisa isofthiwe ezenzakalelayo ekuhloleni amandla okudonsa (tensile strength testing) njenge-SmartPull yakwaWangtebei kunikeza izinzuzo eziningi, okuhlanganisa ukuqeda amaphutha okubhala idatha ngesandla kanye nemijikelezo yokuhlola esheshayo. Isofthiwe libala ngokuzenzakalelayo imingcele ebalulekile efana namandla aphezulu (maximum force), ukunwebeka lapho kugqamuka khona (elongation at break), i-modulus, namandla okukhiqiza (yield strength), okonga isikhathi futhi kuthuthukise ukungaguquguquki. Likhiqiza amagrafu esikhathi sangempela obudlelwano bokucindezela nokunwebeka (stress-strain curves) anikeza ukuqonda okusheshayo ngokuziphatha kwento. Isofthiwe lingagcina idatha yomlando wokuhlola, linikeze ukuhlaziywa kwemikhuba nokuqhathaniswa kwezikhathi ezahlukene. Amasistimu amaningi abuye akhiqize imibiko yokuhlola engaguquguquki (customizable test reports) ukuze kugcinwe imibhalo yekhwalithi nokuxhumana namakhasimende, okwenza kube lula ukuhambisana namazinga ekhwalithi.

Umshini wokuhlola ukudonsa (tensile testing machine) kufanele ngokuvamile uhlolwe (calibrated) okungenani kanye njalo ngezinyanga eziyi-12, nakuba ukuhlolwa njalo kungase kudingeke kuye ngokusetshenziswa, imithetho yezimboni, noma izidingo zamakhasimende. Izinhlelo eziningi zokuphatha ikhwalithi, njenge-ISO 9001, ziyala ukuthi kwenziwe ukuhlolwa minyaka yonke yilabhorethri egunyaziwe ukuze kuqinisekiswe ukulandeleka kwezilinganiso. Uma umshini usetshenziswa kakhulu, uthuthwa uyiswe kwenye indawo, noma ulungiswa, kuyelulekwa ukuthi uhlolwe kabusha ngokushesha. Ukuhlolwa njalo kuqinisekisa ukuthi izilinganiso zomthwalo, ukunwebeka, nesivinini zihlala zinembile, okubalulekile ekuqinisekiseni ikhwalithi ethembekile. I-Wangtebei ihlinzeka ngeziqondiso zokuhlola nokusekela ukuze isize amakhasimende agcine imishini yabo isesimweni esihle kakhulu.
