Umjovo wokubumba iraba ye-silicone efaka ugwebu kuyinqubo ehlanganisa irabha ye-silicone ewuketshezi (LSR) nento eyenza amagwebu futhi, ngemva kokushisisa nokucindezela, yakha umkhiqizo onwetshiwe onezimbotshana esikhunjeni ngesikhathi esisodwa.Inqubo eyinhloko imi kanje:
Ukulungiswa nokuxutshwa kwempahla eluhlaza:
Irabha ye-silicone ewuketshezi (LSR) isetshenziswa njengerabha eyisisekelo, evamise ukuba -izingxenye ezimbili (ingxenye ye-A/B). Xuba kahle ijeli ye-silicone ewuketshezi nama-agent akhihlizayo amakhemikhali (inhlanganisela evamise ukubola ukuze ikhiqize igesi emazingeni okushisa athile) kanye nokunamathisela kombala okudingekile nezinye izithasiselo. Inqubo yokuxuba kufanele ifane futhi igweme ukwethula igesi kusengaphambili.
Ukubumba umjovo:
Izinto eziwuketshezi-ezixutshwe kahle zithunyelwa emgqonyeni womshini wokubumba umjovo ngepompo yokukala. Umshini ujova inani elithile lezinto eziwuketshezi endaweni{2}}yangaphambili yesikhunta esishisayo. Ngalesi sikhathi, izinga lokushisa lesikhunta livame ukulawulwa ngaphansi kwezinga lokushisa lokubola kwe-ejenti enegwebu ukuvimbela ukugwedla ngaphambi kwesikhathi phakathi nenqubo yokugcwalisa isikhunta.
Ukwenza amagwebu kanye ne-vulcanization:
Lapho isikhunta sigcwaliswa, izinga lokushisa lesikhunta likhuphuka ngokushesha ngaphezu kwezinga lokushisa elibolayo le-ejenti enegwebu (ngokuvamile liphakathi kuka-130℃kanye ne-180 degree), I-ejenti enegwebu iqala ukubola lapho ishisa, ikhiqiza amagesi (afana ne-nitrogen), akha inqwaba yamaseli amancane avaliwe ngaphakathi kwe-silica gel matrix.
Ukupholisa nokudiliza:
Ngemuva kokuthi i-vulcanization isiqediwe, linda ukuthi isikhunta siphole, bese uvula isikhunta ukuze ukhiphe umkhiqizo.
