1. Ukhetho oluchanekileyo:
Ngokweemeko zezixhobo kunye neemveliso eziveliswayo, ingubo efanelekileyo ikhethiwe.
2. Lungisa isithuba se-roller ukuqinisekisa ukuba umgca osemgangathweni uthe tye, awuphambuki, kwaye unqanda ukugoqa.
3. Qaphela amacala amahle kunye namabi
Ngenxa yeendlela ezahlukeneyo zokubeka, iingubo zohlulwe ngamacala angaphambili nangasemva, umphambili weengubo zenkampani zinegama elithi "ngaphambili", kwaye umphambili kufuneka uqondiswe lutolo lwangaphandle, ngokuhambelana nesalathiso sokusebenza komatshini wephepha, kwaye ukuxinezeleka kwengubo kufuneka kube kuphakathi ukuthintela uxinzelelo okanye ukukhululeka kakhulu.
Iingubo zokwenza iphepha ziyahlanjwa kwaye zicinezelwe nge-3-5% yesepha yamanzi e-alkali iiyure ezi-2, kwaye amanzi ashushu malunga ne-60 °C angcono. Emva kokuveliswa kwephepha elincinci, ingubo entsha imanziswe ngamanzi, ixesha lokuthambisa kufuneka libe malunga neeyure ezingama-2-4. Ixesha lokuthambisa i-asbestos tile blanket kufuneka libe malunga neeyure ezingama-1-2 emva kokumanzisa ngamanzi acocekileyo. Akuvunyelwe ukomisa umqulu wengubo ngaphandle kokumanzisa ngamanzi.
4. Xa ingubo ikumatshini, kunqanda udaka lwe-oyile yeshaft engcolisa ikhaphethi.
5. Isiqulatho sefayibha yekhemikhali yengubo enenaliti ingaphezulu, kwaye ukuhlanjululwa kweasidi okugxininisiweyo kufuneka kuphetshwe.
6. Inaliti ehlanjululweyo yengubo inomxholo omkhulu wamanzi, kwaye xa i-embossing, i-vacuum suction okanye i-extrusion roller ingcinezelo yomgca inokunyuswa, kwaye i-roller ye-downward pressure roller ixhotyiswe ngommese we-drainage wefosholo ukwenza ukukhutshwa kwamanzi kumacala omabini kunye nokunciphisa umswakama wephepha.
7. I-fiber ye-staple kunye ne-filler kwi-pulp, kulula ukuyivala ingubo, ukuvelisa i-embossing, inokuhlanjwa ngokutshiza amanzi kumacala omabini kunye nokwandisa uxinzelelo lokugungxula, kukulungele ukuqengqeleka kunye nokuhlamba emva kwetanki yamanzi ashushu malunga nama-45 degrees Celsius. Kuphephe ukuxukuxa iingubo ngebrashi eqinileyo xa uhlamba.
8. Inaliti egqojoziweyo ibhayiti ithe tyaba kwaye ingqindilili, akukho lula ukuyisonga, kwaye akufuneki ivuleke iqine kakhulu. Ukuba ingubo ibanzi kakhulu ukuba ingatsala, sebenzisa i-iron ye-soldering yombane ukuvula i-edge okanye ukusika i-edge ngesikere kwaye usebenzise i-iron soldering yombane ukutywina umda.
9.Eminye imiyalelo kunye neemfuno
9.1 Ingubo kufuneka igcinwe ngokwahlukileyo kwizinto zekhemikhali kunye nezinye izinto ukuphepha umonakalo we-corrosion kwingubo.
9.2 Indawo apho ingubo igcinwe khona kufuneka yome kwaye ifakwe umoya, kwaye kufuneka ibekwe phantsi, ngokukhethekileyo ingami ngokuthe tye, ukuthintela umcimbi wokukhulula kunye nokuqinisa kwelinye.
9.3 Ingubo ayifanele igcinwe ixesha elide, ngenxa yeempawu zemichiza yeekhemikhali, ukugcinwa kwexesha elide kunempembelelo enkulu ekutshintsheni ubungakanani bengubo.
