Intshayelelo yemveliso kunye neempawu zayo

I-Styrene, yi-organic compound, ifomula yekhemikhali yi-C8H8, i-electron ye-vinyl kunye ne-benzene ring conjugate, ayinyibiliki emanzini, inyibilika kwi-ethanol, i-ether kunye nezinye izinyibilikisi ze-organic, yi-monomer ebalulekileyo ye-synthetic resin, i-ion exchange resin kunye nerabha yokwenziwa.

sebenzisa

Eyona ndlela ibalulekileyo yokusebenzisa irabha yokwenziwa kunye neplastiki, esetyenziselwa ukuvelisa irabha ye-styrene butadiene, i-polystyrene, i-polystyrene foam; Ikwasetyenziselwa ukwenza i-copolymer kunye nezinye ii-monomers ukwenza iiplastiki zobunjineli ezinokusetyenziswa ezahlukeneyo. Njenge-acrylonitrile, i-butadiene copolymer i-ABS resin, esetyenziswa kakhulu kwiindidi ezahlukeneyo zezixhobo zasekhaya kunye nemizi-mveliso; i-SAN copolymerized ene-acrylonitrile yi-resin enokumelana nempembelelo kunye nombala oqaqambileyo. I-SBS copolymerized ene-butadiene luhlobo lwerabha ye-thermoplastic, esetyenziswa kakhulu njenge-polyvinyl chloride, i-polypropylene modifier.
I-Styrene isetyenziswa kakhulu ekuveliseni i-styrene series resin kunye ne-styrene. I-BUTADIene rubber ikwayenye yezinto ezisetyenziswa ekuveliseni i-ion exchange resin kunye namayeza, ukongeza, i-styrene ingasetyenziswa nakwimveliso yamayeza, idayi, izibulala-zinambuzane kunye nokucubungula izimbiwa kunye neminye imboni. 3. Ukusetyenziswa:
Ukuze isebenze kakuhle, kuyacetyiswa ukuba yongezwe emva kokuxutywa. Ubungakanani bamanzi asetyenzisiweyo buxhomekeke kakhulu kwinkqubo yokufaka isicelo. Umsebenzisi kufuneka amisele ubungakanani obufanelekileyo ngokuzama ngaphambi kokusebenzisa.

iphakheji kunye nothutho

B. Le mveliso ingasetyenziswa, 200KG, 1000KG ibharele yeplastiki.
C. Gcina ivalwe kwindawo epholileyo, eyomileyo nengena umoya ngaphakathi. Izikhongozeli mazivalwe kakuhle emva kokusetyenziswa ngakunye ngaphambi kokusetyenziswa.
D. Le mveliso kufuneka ivalwe kakuhle ngexesha lokuthuthwa ukuze kuthintelwe ukufuma, i-alkali enamandla kunye ne-asidi, imvula kunye nezinye izinto ezingcolileyo ukuba zingaxubeki.
