Product Application

PnB chimagwiritsidwa ntchito kwambiri ngati chotsukira pochotsa zowononga kwambiri. Ikhoza kusungunula mafuta ophatikizana ndi mafuta mogwira mtima ndikudzipanga kukhala yoyenera kwa nyumba ndi mafakitale. Kusungunuka pang'ono m'madzi, PnB imatha kusungunula zosungunulira zambiri ndikugwiritsa ntchito motere:

① monga zotsukira m'nyumba ndi m'mafakitale, zochotsera mafuta ndi utoto, zolumikizira ndi zosungunulira zachitsulo ndi zotsukira zolimba;

② monga cholumikizira chothandizira komanso chosungunulira cha zokutira zochepetsera madzi;

③ monga ogwira coagulating wothandizila madzi ofotokoza emulsion utoto;

④ monga zosungunulira zosungunulira zochokera utoto;

⑤ monga mankhwala apakatikati a ester, zosungunulira ndi plasticizer kupanga.

DPnB
Ntchito mu coating:monga imodzi mwazinthu zabwino kwambiri zopangira mafilimu opangira utoto wopangidwa ndi madzi, DPnB itha kugwiritsidwa ntchito ngati coagulant of acrylic resin, phenylethylene acrylic resin ndi polyvinyl acetate yopereka ntchito yabwino kwambiri yopenta filimu.
Ntchito mu cleanser: imagwira ntchito kwa oyeretsa makamaka omwe amafunikira liwiro lotsika, monga chochotsera sera ndi chotsuka pansi. Monga cholumikizira chabwino chopaka mafuta ndi mafuta, DPnB itha kugwiritsidwa ntchito ngati chodulira utoto komanso chochotsera mafuta anyama.
Ntchito ina:DPnB itha kugwiritsidwanso ntchito pazaulimi, zodzoladzola, inki yamagetsi ndi nsalu.
