Product Application

PnB inonyanya kushandiswa seyekuchenesa mumiririri wezvinorema zvinosvibisa. Inogona kunyungudutsa mafuta ekubatanidza uye girizi zvakanaka uye inozviita yakakodzera fomu yeimba uye maindasitiri. Inonyungudika zvishoma mumvura, PnB inogona kunyungudutsa yakanyanya kunyungudika nekushandisa sezvinotevera:

① semusha uye indasitiri yekuchenesa, inobvisa girisi nependi, yekubatanidza mumiriri uye inonyungudutsa yesimbi uye yakaoma nzvimbo yekuchenesa;

② seanoshanda coupling agent uye solvent yemvura-inoderedza coating;

③ seinoshanda coagulating mumiririri wemvura-based emulsion pendi;

④ seyakanyungudika inonyungudutsa yependi-yakavakirwa pendi;

⑤ semakemikari epakati ester, solvent uye plasticizer kugadzira.

DPnB
Kushandiswa mucoating:seimwe yeakanakisa firimu-inogadzira anobatsira emvura-yakavakirwa pendi, DPnB inogona kushandiswa se coagulant ye acrylic resin, phenylethylene acrylic resin uye polyvinyl acetate inopa kuita kwakanakisa kupenda firimu.
Kushandisa mukuchenesa: inoshanda kune vanochenesa maajenti kunyanya kune ayo anoda yakaderera kuvhurika kumhanya, senge wax remover uye floor cleanser. Seyakanaka coupling agent yekuzora mafuta nemafuta, DPnB inogona kuiswa sependi stripper uye inobvisa mafuta emhuka.
Kumwe kushanda:DPnB inogona zvakare kushandiswa mune zvekurima zvigadzirwa, zvekuzora, zvemagetsi inki uye machira.
