Isinyathelo sokuqala sokuxuba ukulawula okuqukethwe kwesithako ngasinye kanye nokushisa kokubhaka, ukuze ubulukhuni nezithako zikwazi ukuzinza. Ngemva kokuxuba, ngoba i-colloid isenokungcola futhi ayifani, kumele ihlungwe. Ngaphezu kokuqinisekisa ukuthi i-colloid ayinakungcola, isihlungi kumele futhi siqinisekise ukuthi i-roller yerabha ingacindezelwa ngokulinganayo ngesikhathi sokusebenza. Isinyathelo sokwenza ama-roller erabha nokuhlunga sibaluleke kakhulu emishinini yokunyathelisa esheshayo, ukuze kuvinjelwe ukwanda noma ukufinyela okubangelwa yizizathu ezahlukene.
Ngemuva kwalokho i-roller yerabha yezimboni iyashiswa, icindezelwe futhi ivulcanized ukuze kuqiniswe i-plasticizer, ukuze uma irabha isincipha ngesikhathi sokusetshenziswa, ukuncipha kungancishiswa kube kuncane kakhulu. Inqubo yokulungisa ingenza ithambe futhi iqine ngaphandle kokulahlekelwa ubumnene bayo, futhi ekugcineni ingadlulisela kangcono uyinki.
Okokugcina ukugaya nokupholisha. Awudingi izinga lokushisa elingaguquki njalo kulezi zinyathelo ezimbili. Ngaphandle kwalokho, izinga lokushisa liphansi kakhulu, kulula ukuba liqhekeke endaweni, futhi izinga lokushisa liphezulu kakhulu. Ubuso berola yerabha yezimboni buvame ukubangelwa yi-carbonization, futhi isimo sokuqhekeka senzeka ngesikhathi sokuphrinta, okuzobangela ukuthi ikhwalithi yerola yerabha yehle, ngaphandle kwezimpawu zayo ezinhle, futhi ayikwazi ukudlulisa kahle uyinki. , Okubangela imfucuza. Lezi zinyathelo ezimbili zokugcina ziyisihluthulelo sokunquma ikhwalithi yerola yerabha. Nakuba ubuso berola yerabha yezimboni bubukeka bubushelelezi, kusenezinkinga eziningi ezincane ebusweni. Ukugaya nokupholisha kwenzelwa ukwenza irola yerabha ibe nembe kakhudlwana ngobukhulu, indawo ebushelelezi, ukusebenza okungcono kokudlulisa uyinki, kanye nekhwalithi ephezulu yokuphrinta.
