■ Neoprene (CR):
A polima akoso nipa emulsion polymerization ti chloroprene monomer.Molikula roba yii ni awọn ọta chlorine, nitorinaa akawe pẹlu roba idi-gbogboogbo miiran: O ni egboogi-oxidation ti o dara julọ, anti-ozone, ti kii-flammable, piparẹ-ara lẹhin ina, resistance epo, resistance epo, acid ati alkali resistance, ati ti ogbo. ati gaasi resistance.Ti o dara wiwọ ati awọn miiran anfani.
✔ O dara fun wiwọn sisan ti omi tẹ ni kia kia, omi ile-iṣẹ, omi okun ati awọn media miiran.
■ roba Polyurethane (PU):
O jẹ polymerized nipasẹ polyester (tabi polyether) ati diisocyanamide lipid yellow.O ni awọn anfani ti líle ti o ga, agbara ti o dara, rirọ giga, resistance yiya ga, resistance omije, resistance ti ogbo, resistance osonu, resistance itankalẹ ati adaṣe itanna to dara.
✔ O dara fun wiwọn sisan ti awọn media slurry gẹgẹbi pulp ati erupẹ irin.
■Polytetrafluoroethylene (P4-PTFE)
O jẹ polima ti a pese sile nipasẹ polymerization ti tetrafluoroethylene bi monomer kan.White waxy, translucent, ooru resistance, tutu resistance, le ṣee lo ni -180 ~ 260°C gun-igba.Ohun elo yii ni awọn abuda ti acid ati resistance alkali, resistance si ọpọlọpọ awọn olomi Organic, resistance si hydrochloric acid farabale, sulfuric acid, aqua regia, ipata alkali ogidi.
✔ Le ṣee lo fun acid corrosive ati omi iyọ alkali.
■Polyperfluoroethylene propylene (F46-FEP)
O ni iduroṣinṣin kemikali ti o dara julọ ati resistance itọsi itosi, bi daradara bi aiṣe flammability, itanna to dara ati awọn ohun-ini ẹrọ.Awọn ohun-ini kemikali rẹ jẹ deede si polytetrafluoroethylene, pẹlu titẹ agbara ati agbara fifẹ dara ju polytetrafluoroethylene.
✔ Le ṣee lo fun acid corrosive ati omi iyọ alkali.
■Copolymer ti tetrafluoroethylene ati perfluorocarbon nipasẹ vinyl ether (PFA)
Ohun elo ikanra fun ẹrọ itanna eleto ni awọn ohun-ini kemikali kanna bi F46 ati agbara fifẹ to dara julọ ju F46.
✔Le ṣee lo fun acid corrosive ati omi iyọ alkali.
