1. Ukhetho oluchanekileyo:
Ngokweemeko zezixhobo kunye neemveliso ezivelisiweyo, kukhethwa ingubo efanelekileyo.
2. Lungisa isithuba serola ukuqinisekisa ukuba umgca oqhelekileyo uthe tye, awujiki, kwaye uthintela ukugoba.
3. Qaphela amacala amahle nangalunganga
Ngenxa yeendlela ezahlukeneyo zokubeka, iingubo zahlulwe ngamacala angaphambili nangasemva, umphambili weengubo zenkampani unegama elithi “umphambili”, kwaye umphambili kufuneka uqondiswe lutolo olungaphandle, oluhambelana necala lokusebenza komatshini wephepha, kwaye uxinzelelo lwengubo kufuneka lube phakathi ukuze kuthintelwe uxinzelelo olugqithisileyo okanye ukukhululeka kakhulu.
Iingubo zokwenza iphepha zihlala zihlanjwa kwaye zicinezelwe ngesepha ye-3-5% yamanzi e-alkali kangangeeyure ezi-2, kwaye amanzi afudumeleyo malunga nama-60 °C angcono. Emva kokuveliswa kwephepha elincinci, ingubo entsha imanziswa ngamanzi, ixesha lokuthamba kufuneka libe malunga neeyure ezi-2-4. Ixesha lokuthamba lengubo yethayile ye-asbestos kufuneka libe malunga neyure e-1-2 emva kokuba imanziswe ngamanzi acocekileyo. Akuvumelekanga ukomisa ugoqe ingubo ngaphandle kokumanziswa ngamanzi.
4. Xa ingubo ikwimatshini, kuphephe ukuba inkunkuma yeoyile yentloko yeshaft ingcolise ikhaphethi.
5. Umxholo wefayibha yeekhemikhali kwingubo eneenaliti ungaphezulu, kwaye ukuhlanjwa nge-asidi exineneyo kufuneka kuthintelwe.
6. Ingubo ebhobozwe ngenaliti inomthamo omkhulu wamanzi, kwaye xa ifakwa i-embossing, uxinzelelo lwe-vacuum suction okanye i-extrusion roller line lunokwandiswa, kwaye i-downward pressure roller ifakwe imela yefosholo yokukhupha amanzi ukuze amanzi aphume kumacala omabini kwaye anciphise ukufuma kwephepha.
7. Ifayibha eyomeleleyo kunye ne-filler kwi-pulp, kulula ukuyivala ingubo, ivelisa i-embossing, ingahlanjwa ngokutshiza amanzi kumacala omabini kwaye yonyuse uxinzelelo lokuhlanjwa, kungcono ukuyiqengqa nokuhlamba emva kokufaka itanki yamanzi ashushu angama-45 degrees Celsius. Kuphephe ukuxubha iingubo ngebrashi eqinileyo xa uhlamba.
8. Ingubo ebhobozwe ngenaliti ithe tyaba kwaye ityebile, akulula ukuyisonga, kwaye akufuneki ivulwe iqine kakhulu. Ukuba ingubo inkulu kakhulu ukuba ingatsalwa, sebenzisa intsimbi yombane yokugalela ukuvula umphetho okanye usike umphetho ngesikere uze usebenzise intsimbi yombane yokugalela ukuvala umphetho.
9. Eminye imiyalelo kunye neemfuno
9.1 Ingubo mayigcinwe yodwa kwizinto ezisetyenziswa ngamakhemikhali nezinye izinto ukuze kungabikho monakalo kwingubo.
9.2 Indawo egcinwe kuyo ingubo mayibe yomile kwaye ingeniswe umoya, kwaye mayibekwe ngokuthe tyaba, kungcono ukuba ingabi ime nkqo, ukuthintela ukuba ingakhululeki kwaye iqine kwenye.
9.3 Ingubo akufuneki igcinwe ixesha elide, ngenxa yeempawu zeemicu zeekhemikhali, ukugcinwa ixesha elide kunempembelelo enkulu kutshintsho lobukhulu bengubo.
