Mapulogalamu a PVB
1. Filimu yopyapyala imagwiritsidwa ntchito kupanga masangweji zipangizo zamagalasi otetezeka.Galasi yotetezeka ndi yabwino komanso imakhala ndi mphamvu zambiri.Amagwiritsidwa ntchito kwambiri m'munda wa ndege ndi magalimoto.
2. Amagwiritsidwa ntchito popanga zokutira pansi zitsulo ndi utoto wozizira wokhala ndi zitsulo zolimba komanso kukana madzi ndi kumatira mwamphamvu komanso kukana madzi.
3. Amagwiritsidwa ntchito popanga pepala lowala lamaluwa, lomwe lingalowe m'malo mwa pepala lamaluwa la ceramic.Makampani opanga utomoni amagwiritsidwa ntchito popanga pulasitiki yophwanyira zitsulo zopanda chitsulo monga chitsulo ndi lead, zomwe zimatha kuphatikizidwa ndi zomatira zosiyanasiyana.Amagwiritsidwa ntchito kwambiri polumikizira matabwa, ceramic, zitsulo, pulasitiki, zikopa, wosanjikiza wa zida zokakamiza.
4. Amagwiritsidwa ntchito popanga mankhwala othandizira nsalu ndi chubu cha gauze.Makampani opanga zakudya amagwiritsidwa ntchito popanga zida zakupha.
5. Makampani opanga mapepala amagwiritsidwa ntchito popanga mankhwala othandizira mapepala.Kuphatikiza apo, itha kugwiritsidwa ntchito popanga anti-shrinkables, othandizira olimba ndi zinthu zina zopanda madzi.
6. Itha kugwiritsidwa ntchito pakukoma mtima kwamakampani osindikizira, kusindikiza kwa concave, kusindikiza kwa convex, kusindikiza ukonde wa silika, kutengerapo kutentha, chifukwa kumasungunuka mu mowa komanso kusakhala ndi poizoni, chisindikizo sichikhalabe fungo, chomwe chingagwiritsidwe ntchito. m’makampani azakudya omwe amamva fungo lazakudya.Monga tiyi/fodya.Chifukwa utomoniwo ndi wamtundu wa cedic, umamatira bwino kwambiri pagalasi lokhala ndi yin ion yolimba, yomwe ili yoyenera makamaka kukongoletsa magalasi a silika.
