Kugwiritsa Ntchito Mankhwala

PnBimagwiritsidwa ntchito makamaka ngati chotsukira zinthu zodetsa kwambiri. Imatha kusungunula mafuta olumikizira ndi mafuta bwino ndikudzipangitsa kukhala yoyenera kugwiritsidwa ntchito m'nyumba ndi m'mafakitale. Posungunuka pang'ono m'madzi, PnB imatha kusungunula zosungunulira zambiri pogwiritsa ntchito motere:

① monga chotsukira chapakhomo ndi mafakitale, chochotsera mafuta ndi utoto, cholumikizira ndi chosungunulira chachitsulo ndi chotsukira cholimba;

② ngati cholumikizira chogwira ntchito komanso chosungunulira cha zokutira zochepetsera madzi;

③ ngati chothandizira chogwira ntchito chophatikizana cha utoto wa emulsion wochokera m'madzi;

④ ngati chosungunulira chogwira ntchito cha utoto wopangidwa ndi zosungunulira;

⑤ ngati mankhwala apakati opangira ester, solvent ndi plasticizer.

DPnB
Kugwiritsa ntchito popaka:Monga imodzi mwa njira zabwino kwambiri zopangira utoto wopangidwa ndi madzi, DPnB ingagwiritsidwe ntchito ngati coagulant ya acrylic resin, phenylethylene acrylic resin ndi polyvinyl acetate zomwe zimapangitsa kuti filimu ipente bwino.
Kugwiritsa ntchito mu chotsukira:Imagwira ntchito pa zotsukira makamaka zomwe zimafuna liwiro lochepa, monga chochotsera sera ndi chotsukira pansi. Monga cholumikizira chabwino chopaka mafuta ndi mafuta, DPnB ingagwiritsidwe ntchito ngati chochotsera utoto ndi chochotsera mafuta a nyama.
Ntchito ina:DPnB ingagwiritsidwenso ntchito mu zinthu zaulimi, zodzoladzola, inki yamagetsi ndi nsalu.
