Kushandiswa Kwechigadzirwa

PnBInonyanya kushandiswa semushonga wekuchenesa zvinhu zvinosvibisa zvakawanda. Inogona kunyungudutsa mafuta ekubatanidza nemafuta zvinobudirira uye inozvigadzira yakakodzera fomura yemumba neyemaindasitiri. PnB, inonyungudika zvishoma mumvura, inogona kunyungudutsa solvent yakawanda nekushandisa seizvi:

1 semushonga wekuchenesa wemumba neindasitiri, mubvisi wemafuta nependi, musanganiswa wesimbi nesimbi inochenesa pamusoro pakaoma uye solvent;

② semushonga unoshanda wekubatanidza uye mushonga unonyungudutsa wepurasitiki unoderedza mvura;

③ semushonga unoshanda wekudzivirira pendi yemvura;

④ semushonga unoshanda wependi yakagadzirwa nemushonga;

⑤ senzira yemakemikari yekugadzira ester, solvent uye plasticizer.

DPnB
Kushandiswa mukuputira:Seimwe yeakanakisa ekubatsira pendi dzinobva mumvura, DPnB inogona kushandiswa se coagulant ye acrylic resin, phenylethylene acrylic resin uye polyvinyl acetate zvichipa mashandiro akanaka ekupenda firimu.
Kushandiswa mukuchenesa:Inoshanda kune zvinhu zvinochenesa kunyanya kune izvo zvinoda kumhanya kushoma, zvakaita sekubvisa wakisi uye kuchenesa pasi. Sechinhu chakanaka chekubatanidza mafuta nemafuta, DPnB inogona kushandiswa semuchina wekubvisa pendi uye kubvisa mafuta emhuka.
Mamwe mashandisirwo:DPnB inogona kushandiswawo muzvigadzirwa zvekurima, zvizoro, inki yemagetsi uye machira.
