Kusuma chigadzirwa uye maitiro
Styrene, is an organic compound, chemical formula is C8H8, the electron of vinyl and benzene ring conjugate, isinganyunguriki mumvura, inonyungudika mu ethanol, ether nezvimwe zvinonyungudutsa organic, inokosha monomer ye synthetic resin, ion exchange resin uye synthetic rubber.
use
Iyo inonyanya kukosha inoshandiswa seyakagadzirwa rubber uye plastiki monomer, inoshandiswa kugadzira styrene butadiene rubber, polystyrene, polystyrene foam;Inoshandiswawo kuita copolymerize nemamwe monomers kugadzira einjiniya mapurasitiki ekushandisa kwakasiyana.Zvakadai se acrylonitrile, butadiene copolymer ABS resin, inoshandiswa zvakanyanya mumhando dzakasiyana dzemidziyo yemumba neindasitiri;SAN copolymerized ne acrylonitrile iresin inopikisa uye inopenya ruvara.SBS copolymerized with butadiene imhando ye thermoplastic rabha, inoshandiswa zvakanyanya se polyvinyl chloride, polypropylene modifier.
Styrene inonyanya kushandiswa mukugadzira styrene series resin uye styrene BUTADIene rubber, zvakare imwe yezvigadzirwa zvekugadzirwa kweion exchange resin nemishonga, uyezve, styrene inogona kushandiswawo mumishonga, dhayi, pesticide uye mineral processing. nemamwe maindasitiri.3. Kushandisa:
Kuti uite zvakanakisisa, zvinokurudzirwa kuwedzera mushure mekugadzirisa.Kuwanda kwemvura inoshandiswa kunoenderana zvakanyanya nehurongwa hwekushandisa.Mushandisi anofanira kuona huwandu hwepamusoro kuburikidza nekuedza asati ashandisa.s.
pasuru uye chokufambisa
B. Ichi chigadzirwa chinogona kushandiswa, 200KG, 1000KG bhodhoro repurasitiki.
C. Chengetedza chakavharwa munzvimbo inotonhorera, yakaoma uye inofefetera mukati memba.Midziyo inofanira kuvharwa zvakasimba mushure mekushandiswa kwega kwega isati yashandiswa.
D. Ichi chigadzirwa chinofanira kuiswa chisimbiso zvakanaka panguva yekufambisa kudzivirira unyoro, alkali yakasimba uye asidi, mvura uye zvimwe tsvina kubva pakusanganiswa.
