Isicelo seMveliso

I-PnBIsetyenziswa kakhulu njengesixhobo sokucoca izinto ezingcolisayo kakhulu. Inganyibilikisa ioyile yokudibanisa kunye negrisi ngokufanelekileyo kwaye izenze ifaneleke kwifomyula yasekhaya neyemizi-mveliso. Inyibilika kancinci emanzini, iPnB inokunyibilikisa uninzi lwesinyibilikisi ngokusetyenziswa ngolu hlobo lulandelayo:

1. njengesicoci sasekhaya nesemizi-mveliso, isisusi segrisi kunye nepeyinti, iarhente yokudibanisa kunye nesinyibilikisi sesinyithi kunye nesicoci somphezulu oqinileyo;

② njengesixhobo esisebenzayo sokudibanisa kunye nesinyibilikisi seengubo zokunciphisa amanzi;

③ njengearhente yokujiya esebenzayo yepeyinti ye-emulsion esekwe emanzini;

④ njengesinyibilikisi esisebenzayo sepeyinti esekelwe kwisinyibilikisi;

⑤ njengesixhobo esiphakathi seekhemikhali sokwenza i-ester, i-solvent kunye ne-plasticizer.

I-DPnB
Isicelo kwi-coating:Njengenye yezona zinto zibalaseleyo zokwenza ifilimu kwiipeyinti ezisekelwe emanzini, i-DPnB ingasetyenziswa njenge-coagulant ye-acrylic resin, i-phenylethylene acrylic resin kunye ne-polyvinyl acetate enika ukusebenza okuhle kakhulu ekupeyinteni ifilimu.
Ukusetyenziswa kwi-cleanser:Isebenza kwiiarhente zokucoca ingakumbi kwezo zifuna isantya esiphantsi sokuguquguquka, ezifana nesixhobo sokususa iwax kunye nesicoci somgangatho. Njengesixhobo esifanelekileyo sokudibanisa igrisi namafutha, i-DPnB ingasetyenziswa njengesicoci sepeyinti kunye nesisusa amafutha ezilwanyana.
Olunye usetyenziso:I-DPnB ingasetyenziswa nakwimveliso yezolimo, izinto zokuthambisa, i-inki ye-elektroniki kunye nempahla yokunxiba.
