Emhlabeni wokukhiqiza,izingxenye zomshini ngokwezifisoidlala indima ebalulekile ekwakheni imikhiqizo ehlangabezana nezidingo ezithile. Into eyodwa ethole ukuduma ngenxa yokuguquguquka kwayo kanye nokuqina emishinini yangokwezifiso i-polioxymethylene (POM), eyaziwa nangokuthi i-acetal noma i-Delrin. I-POM iyipulasitiki yobunjiniyela esebenza kahle kakhulu enikeza ukuzinza okuhle kakhulu kobukhulu, ukungqubuzana okuphansi, nokuqina okuphezulu, okuyenza ibe ukukhetha okuhle kwezicelo eziningi. Izingxenye zomshini ezenziwe ngokwezifiso ezinempahla ye-POM seziyinto ekhethwayo ezimbonini ezinjengezezimoto, i-aerospace, impahla yezokwelapha, kanye nezabathengi ngenxa yezakhiwo zayo ezihlukile zokuwumshini kanye nokumelana nokuguga. Ikhono le-POM lokumelana nezinga lokushisa eliphezulu kanye nezindawo ezinokhahlo liyenza ifanelekele izinhlelo zokusebenza ezifunayo lapho ukunemba nokuthembeka kubaluleke kakhulu.
Enye yezinzuzo ezibalulekile zokusebenzisaImpahla ye-POMngoba ngokwezifiso izingxenye machining kuyinto machinability yayo. I-POM ingenziwa kalula ngomshini ukuze idale izimo eziyinkimbinkimbi kanye nemiklamo eyinkimbinkimbi enokubekezelelana okuqinile, okuyenza ibe yisixazululo esingabizi kakhulu sokukhiqiza izingxenye zangokwezifiso ngokunemba okuphezulu. Lokhu kusebenza kahle kuvumela abakhiqizi ukuthi bathole imininingwane eyinkimbinkimbi kanye nokuqeda okuhle, bahlangabezane nemininingwane eqondile yamakhasimende abo. Ngaphezu kwalokho, izingxenye zomshini wangokwezifiso ezinempahla ye-POM zinikeza ukumelana okuhle kakhulu namakhemikhali, izincibilikisi, namafutha, okuzenza zifanelekele izinhlelo zokusebenza lapho ukuchayeka ezintweni ezinokhahlo kuwukukhathazeka. Lokhu kumelana kwamakhemikhali kuqinisekisa ukuphila isikhathi eside nokuthembeka kwezingxenye ezenziwe ngomshini, ngisho nasezindaweni zokusebenza eziyinselele.
Iezezimotoimboni, ikakhulukazi, yamukele ukusetshenziswa kwezingxenye zomshini ezenziwe ngokwezifiso ezinempahla ye-POM yezingxenye ezihlukahlukene ezifana namagiya, ama-bearings, ama-bushings, nezingxenye zesistimu kaphethiloli. Ukumelana nokugqokwa okukhethekile kanye nezakhiwo eziphansi zokungqubuzana kwe-POM ziyenza ibe inketho ekahle yalezi zinhlelo zokusebenza zezimoto ezibalulekile, lapho ukuqina nokusebenza kubalulekile. Emkhakheni we-aerospace, izingxenye zomshini wangokwezifiso ezinempahla ye-POM zisetshenziswa ekukhiqizeni izingxenye zendiza, okuhlanganisa ukufakwa kwangaphakathi, izakhi zesakhiwo, nezingxenye zesistimu yokulawula. Imvelo engasindi ye-POM, ehlanganiswe namandla ayo aphezulu kanye nokuqina kwayo, iyenza inketho ekhangayo kubakhiqizi be-aerospace abafuna ukunciphisa isisindo ngaphandle kokuyekethisa ekusebenzeni nasekuthembekeni.
Imboni yezokwelapha iphinde ihlomule ezingxenyeni zemishini ezenziwe ngokwezifiso ezinempahla ye-POM, njengoba ihlangabezana nezidingo eziqinile zokusebenzisana kwe-biocompatibility nokuvala inzalo. Ukumelana kwe-POM kumswakama kanye namakhemikhali, kanye nekhono layo lokumelana nemijikelezo yokuvala inzalo ephindaphindiwe, kuyenza ibe ukukhetha okuhle kwemishini yezokwelapha nemishini, iqinisekisa ukuphepha nokuphila kahle kweziguli. Ngaphezu kwalokho, imboni yezimpahla zabathengi isebenzisa inkambisoimishiniizingxenye ezinempahla ye-POM yemikhiqizo enhlobonhlobo, okuhlanganisa izinto zikagesi, izinto zikagesi, nezimpahla zemidlalo.
Ukukhanga kobuhle, ukuqina kobukhulu, kanye nokuqedwa kwendawo eshelelayo ye-POM kuyenza ibe yisinqumo esidumile sokudala izingxenye zangokwezifiso ezithuthukisa ukusebenza nokubukeka kwemikhiqizo yabathengi. Sengiphetha, izingxenye zomshini wangokwezifiso ezinomathiriyeli we-POM zinikeza izinkulungwane zezinzuzo, okufaka phakathi ukusebenza ngendlela engavamile, izakhiwo zemishini, ukumelana namakhemikhali, nokufaneleka kwezimboni ezihlukahlukene. Njengoba isidingo sekhwalithi ephezulu, izingxenye eziklanywe ngokwezifiso siqhubeka sikhula, izinto ze-POM ngokungangabazeki zizohlala ziyinketho ephezulu kubakhiqizi abafuna ukuletha ukunemba, ukwethembeka, nokusebenza emikhiqizweni yabo.
