Electromagnetic flowmeter bụ ngwá ọrụ na-eji ụkpụrụ nke induction electromagnetic tụọ eruba nke mmiri na-eduzi na-adabere na ike electromotive kpaliri mgbe mmiri conductive gafere na mpụga magnetik.
Ya mere, otu esi ahọrọ n'ime lining na electrode ihe?
Nhọrọ ihe eji eme ihe
■ Neoprene (CR):
A na-emepụta polymer site na emulsion polymerization nke chloroprene monomer. Nke a rọba molekul nwere chlorine atọm, otú e jiri ya tụnyere ndị ọzọ n'ozuzu nzube rọba: Ọ nwere magburu onwe mgbochi oxidation, mgbochi ozone, non-flammable, onwe-emenyụ mgbe ọkụ, mmanụ iguzogide, mgbaze mgbaze, acid na alkali iguzogide, na ịka nká. na nguzogide gas. Ezigbo tightness na uru ndị ọzọ.
✔ Ọ dị mma maka nha nha nke mmiri mgbata, mmiri mmepụta ihe, mmiri mmiri na mgbasa ozi ndị ọzọ.
■ Polyurethane roba (PU):
A na-eme ya site na polyester (ma ọ bụ polyether) na diisocyanamide lipid compound. Ọ nwere uru nke ịdị elu siri ike, ike dị mma, ịdị elu dị elu, nkwụsị elu dị elu, nkwụsị nke anya mmiri, nkwụsị nke ịka nká, nkwụsị ozone, nkwụsị ọkụ na ọkụ eletrik dị mma.
✔ Ọ dabara adaba maka nha mgbasa nke slurry media dị ka pulp na ore pulp.
■Polytetrafluoroethylene (P4-PTFE)
Ọ bụ polymer a kwadebere site na polymerization nke tetrafluoroethylene dị ka monomer. White waxy, translucent, okpomọkụ na-eguzogide, oyi na-eguzogide, ike ga-eji na -180 ~ 260 ° C ogologo oge. Ihe a nwere njirimara nke acid na alkali eguzogide, iguzogide ihe dị iche iche organic solvents, iguzogide esi hydrochloric acid, sulfuric acid, aqua regia, concentrated alkali corrosion.
✔ Enwere ike iji ya mee acid corrosive na mmiri nnu alkali.
■Polyperfluoroethylene propylene (F46-FEP)
Ọ nwere ezigbo nkwụsi ike nke kemịkalụ yana nguzogide radieshon pụtara ìhè, yana enweghị ọkụ, ezigbo ọkụ eletrik na akụrụngwa. Njirimara kemịkalụ ya na polytetrafluoroethylene, na ike mkpakọ na ike ike dị mma karịa polytetrafluoroethylene.
✔ Enwere ike iji ya mee acid corrosive na mmiri nnu alkali.
■Copolymer nke tetrafluoroethylene na perfluorocarbon site na vinyl ether (PFA)
Ihe mkpuchi maka flumeter electromagnetic nwere otu ihe kemịkalụ dị ka F46 yana ike tensile dị mma karịa F46.
✔Enwere ike iji ya mee acid corrosive na mmiri nnu alkali.
