Ulwazi Lobunzima

1, Ngemva kokucubungula, izingxenye zingase zibe neziqongo ezinkulu noma ezincane nezigodi ebusweni bomsebenzi ngenxa yamathuluzi okusika, amadiphozithi e-chip, nama-burrs. Ukuphakama kwalezi ziqongo nezigodi kuncane kakhulu, ngokuvamile kubonakala kuphela lapho kukhulisiwe. Lesi sici sejiyomethri esincanyana sibizwa ngokuthi ama-surface roughness.
2, Umthelela Wokuqina Okuphezulu Ekusebenzeni Kwezingxenye Zomshini
Ubulukhuni bobuso bunomthelela obalulekile kwikhwalithi yezingxenye, ikakhulukazi ezigxile ekungagugini kwazo, izakhiwo ezilingana, amandla okukhathala, ukunemba kocezu lokusebenza, kanye nokumelana nokugqwala.
① Umthelela wokungqubuzana nokuguga. Umthelela wokuhwalala kwengaphezulu ekugqokeni kwengxenye ubonakala kakhulu esiqongweni nasesiqongweni, lapho izingxenye ezimbili zihlangana khona, empeleni okuwukuthintana okuphezulu okungaphelele. Ukucindezela endaweni yokuxhumana kuphezulu kakhulu, okungabangela ukuthi izinto zingene ku-plastic flow. Lapho ingaphezulu liqinile, ukuguga kunamandla kakhulu.
② Umthelela kuzakhiwo zokuxhumanisa. Kunezinhlobo ezimbili zokulingana kwengxenye, ukulingana kokuphazanyiswa kanye nokulingana kwemvume. Ukuze uthole ukungenelela kokuphazanyiswa, ngenxa yokwehliswa kweziqongo ezingaphezulu ngesikhathi somhlangano, inani lokuphazanyiswa liyancishiswa, okunciphisa amandla okuxhuma ezingxenyeni; Ukuze uvumelane nemvume, njengoba inani eliphakeme lihlala liphansi, izinga lokuvunyelwa lizokhula. Ngakho-ke, ubulukhuni obungaphezulu buthinta ukuzinza kwezakhiwo zokukhwelana.
③ Umthelela wokumelana namandla okukhathala. Uma ingaphezulu lengxenye liqina, kujula imbobo, futhi iba yincane indawo egobile yomkhombe, okuyenza ibe bucayi kakhulu ekugxilweni kwengcindezi. Ngakho-ke, lapho ingxenye engaphezulu ilukhuni kakhulu, ingcindezi igxila kakhulu, futhi iyancipha ukumelana kwayo nokukhathala.
④ Anti corrosive effects. Uma ubukhulu bengxenye buba bukhulu, isigodi sayo samagagasi sijula. Ngale ndlela, uthuli, uwoyela wokugcoba owonakele, izinto ezi-acidic kanye ne-alkaline ezonakalisayo zinganqwabelana kalula kulezi zigodi futhi zingene kungqimba lwangaphakathi lwento, zenze ukugqwala kwezingxenye. Ngakho-ke, ukunciphisa ukuhwalala kwendawo kungathuthukisa ukumelana nokugqwala kwezingxenye.
