Kugwiritsa ntchito PVB
1. Filimu yopyapyala imagwiritsidwa ntchito popanga zinthu za sangweji za galasi lotetezeka. Galasi lotetezeka ndi labwino ndipo lili ndi mphamvu zambiri. Limagwiritsidwa ntchito kwambiri m'magawo a ndege ndi magalimoto.
2. Amagwiritsidwa ntchito popanga zokutira zachitsulo pansi ndi utoto wozizira wokhala ndi kumatira mwamphamvu komanso kukana madzi komanso kumatira mwamphamvu komanso kukana madzi.
3. Amagwiritsidwa ntchito popanga pepala lowala la maluwa, lomwe lingalowe m'malo mwa pepala la maluwa la ceramic. Makampani opanga utomoni amagwiritsidwa ntchito popanga pulasitiki yophwanyira zitsulo zopanda chitsulo monga chitsulo ndi lead, zomwe zingagwirizane ndi zomatira zosiyanasiyana. Amagwiritsidwa ntchito kwambiri polumikiza matabwa, ceramic, chitsulo, pulasitiki, chikopa, ndi zinthu zina zopanikizika.
4. Amagwiritsidwa ntchito popanga zinthu zotsukira nsalu ndi chubu cha gauze. Makampani opanga chakudya amagwiritsidwa ntchito popanga zinthu zopaka poizoni.
5. Makampani opanga mapepala amagwiritsidwa ntchito popanga zinthu zotsukira mapepala. Kuphatikiza apo, angagwiritsidwe ntchito popanga zinthu zoletsa kusweka, zinthu zolimba komanso zinthu zina zosalowa madzi.
6. Itha kugwiritsidwa ntchito pochepetsa kuuma kwa makampani osindikizira, kusindikiza kozungulira, kusindikiza kozungulira, kusindikiza ukonde wa silika, kusamutsa kutentha, chifukwa imasungunuka mu mowa ndipo siimayambitsa poizoni, chisindikizo sichikhalabe fungo, lomwe lingagwiritsidwe ntchito m'makampani ogulitsa chakudya omwe amakhudzidwa ndi fungo m'makampani ogulitsa chakudya. Monga tiyi/ndudu. Chifukwa utomoni ndi wa cedic, umamatira bwino pamwamba pa galasi ndi yin ion yamphamvu, yomwe ndi yoyenera kwambiri kukongoletsa mbale yagalasi.
