Isicelo Somkhiqizo

I-PnBIsetshenziswa kakhulu njenge-ejenti yokuhlanza izinto ezingcolisa kakhulu. Ingancibilikisa uwoyela ohlanganisayo kanye namafutha ngempumelelo futhi izenze ifaneleke efomini yasekhaya neyezimboni. Njengoba incibilika kancane emanzini, i-PnB ingancibilikisa iningi le-solvent ngokusebenzisa le ndlela elandelayo:

① njengesihlanzi sasekhaya nesezimboni, isisusi samafutha nopende, i-ejenti yokuhlanganisa kanye nesinyibilikisi sensimbi nesihlanzi esiqinile;

② njenge-ejenti yokuhlanganisa ephumelelayo kanye nesinyibilikisi sezingubo zokunciphisa amanzi;

③ njenge-ejenti yokuhlanganisa esebenza kahle yopende we-emulsion osekelwe emanzini;

④ njengesinyibilikisi esisebenzayo sopende osuselwe ku-solvent;

⑤ njenge-chemical intermediate yokukhiqiza i-ester, i-solvent kanye ne-plasticizer.

I-DPnB
Isicelo ekumbozeni:Njengenye yezinsiza ezinhle kakhulu zokwakha ifilimu zopende olusekelwe emanzini, i-DPnB ingasetshenziswa njenge-coagulant ye-acrylic resin, i-phenylethylene acrylic resin kanye ne-polyvinyl acetate enikeza ukusebenza okuhle kakhulu kokupenda ifilimu.
Isicelo ku-cleanser:Isebenza ezintweni zokuhlanza ikakhulukazi kulezo ezidinga isivinini esiphansi sokuguquguquka, njengesisusi se-wax kanye nesihlanzi saphansi. Njenge-ejenti enhle yokuhlanganisa amafutha namafutha, i-DPnB ingasetshenziswa njengesisusi sopende kanye nesisusi samafutha ezilwane.
Olunye uhlelo lokusebenza:I-DPnB ingasetshenziswa futhi emikhiqizweni yezolimo, izimonyo, uyinki kagesi kanye nendwangu.
