1. Ukukhetha okulungile:
Ngokwezimo zemishini kanye nemikhiqizo ekhiqizwayo, kukhethwa ingubo efanele.
2. Lungisa isikhala se-roller ukuqinisekisa ukuthi umugqa ojwayelekile uqondile, awuphambuki, futhi uvimbela ukugoqeka.
3. Qaphela izinhlangothi ezinhle nezimbi
Ngenxa yezindlela ezahlukene zokubeka, izingubo zokulala zihlukaniswe ngezinhlangothi zangaphambili nangemuva, ingaphambili lezingubo zokulala zenkampani linegama elithi “ngaphambili”, kanti ingaphambili kumele liqondiswe umcibisholo wangaphandle, okuhambisana nesiqondiso sokusebenza komshini wephepha, futhi ukucindezeleka kwengubo yokulala kumele kube okulinganiselwe ukuvimbela ukucindezeleka ngokweqile noma ukukhululeka kakhulu.
Izingubo zokwenza iphepha ngokuvamile zigezwa futhi zicindezelwe ngensipho engu-3-5% amanzi ane-alkali amahora ama-2, kanti amanzi afudumele cishe ku-60 °C angcono. Ngemva kokukhiqizwa kwephepha elincane, ingubo entsha imanziswa ngamanzi, isikhathi sokuthambisa kufanele sibe cishe amahora ama-2-4. Isikhathi sokuthambisa sengubo yethayela le-asbestos kufanele sibe cishe amahora angu-1-2 ngemva kokumanziswa ngamanzi ahlanzekile. Akuvunyelwe ukomisa ukugoqa ingubo ngaphandle kokumanziswa ngamanzi.
4. Uma ingubo isemshinini, gwema ukungcola kwamafutha ekhanda lomgodi okungcolisa ikhaphethi.
5. Okuqukethwe kwefayibha yamakhemikhali engutsheni enenaliti kukhulu, futhi ukuhlanza nge-asidi egxilile kufanele kugwenywe.
6. Ingubo ebhobozwe ngenaliti inokuqukethwe kwamanzi amaningi, futhi uma ifakwa embossing, ingcindezi yomugqa we-vacuum suction noma i-extrusion roller ingakhushulwa, futhi i-roller yokucindezela ephansi ifakwe ummese wefosholo wokukhipha amanzi ukuze kukhishwe amanzi kuzo zombili izinhlangothi futhi kuncishiswe umswakama wekhasi.
7. I-staple fiber kanye ne-filler ku-pulp, okulula ukuyivimba ingubo, ikhiqiza i-embossing, ingagezwa ngokufafaza amanzi nhlangothi zombili futhi yandise ingcindezi yokugeza, kungcono ukuyigoqa nokugeza ngemva kokufaka amanzi ashisayo angama-degree Celsius angaba ngu-45. Gwema ukuxubha izingubo zokulala ngebhulashi eliqinile lapho ugeza.
8. Ingubo ebhobozwe ngenaliti iyisicaba futhi ijiyile, akulula ukuyigoqa, futhi akufanele ivulwe iqine kakhulu. Uma ingubo inkulu kakhulu ukuba ingadonswa, sebenzisa insimbi kagesi yokugoqa ukuvula umphetho noma usike umphetho ngesikele bese usebenzisa insimbi kagesi yokugoqa ukuvala umphetho.
9. Eminye imiyalelo nezidingo
9.1 Ingubo kufanele igcinwe ngokwehlukana nezinto zamakhemikhali nezinye izinto ukuze kugwenywe umonakalo wokugqwala kwengubo.
9.2 Indawo lapho ingubo igcinwa khona kufanele yome futhi ingeniswe umoya, futhi kufanele ibekwe iqonde, kungcono ingami iqonde, ukuvimbela isimo sokukhululeka nokuqina kwenye.
9.3 Ingubo akufanele igcinwe isikhathi eside kakhulu, ngenxa yezici zemicu yamakhemikhali, ukugcinwa kwesikhathi eside kunomthelela omkhulu ekushintsheni kosayizi wengubo.
