He mea hana ka electromagnetic flowmeter e hoʻohana i ke kumu o ka electromagnetic induction e ana i ke kahe o ka wai conductive e pili ana i ka ikaika electromotive i hoʻokomo ʻia i ka wā e hele ai ka wai conductive i kahi kahua magnetic waho.
No laila pehea e koho ai i ka lining i loko a me nā mea electrode?
Koho Mea Laina
■ Neoprene (CR):
He polymer i hana ʻia e ka emulsion polymerization o ka chloroprene monomer.Loaʻa i kēia mole mole kalapona nā ʻātoma chlorine, no laila ke hoʻohālikelike ʻia me nā ʻāpana kumu nui ʻē aʻe: He anti-oxidation maikaʻi loa, anti-ozone, non-flammable, hoʻopau iā ia iho ma hope o ke ahi, kūpaʻa aila, kūpaʻa solvent, acid and alkali resistance, a me ka ʻelemakule. a me ka pale kinoea.ʻO ka paʻa maikaʻi a me nā pono ʻē aʻe.
✔ He kūpono ia no ke ana kahe ʻana o ka wai paila, ka wai ʻoihana, ka wai kai a me nā mea ʻē aʻe.
■ Puka Polyurethane (PU):
Hoʻopili ʻia e ka polyester (a i ʻole polyether) a me ka diisocyanamide lipid compound.Loaʻa iā ia nā pōmaikaʻi o ka paʻakikī kiʻekiʻe, ka ikaika maikaʻi, ka elasticity kiʻekiʻe, ke kūpaʻa lole kiʻekiʻe, ke kūʻē i ka waimaka, ka pale ʻana i ka wā kahiko, ka pale ʻana o ka ozone, ka pale radiation a me ka conductivity uila maikaʻi.
✔ He kūpono ia no ke ana kahe ʻana o ka media slurry e like me ka pulp a me ka pulp ore.
■Polytetrafluoroethylene (P4-PTFE)
He polymer ia i hoʻomākaukau ʻia e ka polymerization o ka tetrafluoroethylene ma ke ʻano he monomer.Hiki ke hoʻohana i ka waxy keʻokeʻo, translucent, wela wela, pale anuanu, i -180 ~ 260 ° C lōʻihi.Loaʻa i kēia mea nā hiʻohiʻona o ka waikawa a me ke kūpaʻa alkali, ke kū'ē i nā ʻano mea hoʻoheheʻe organik, kūʻē i ka paila hydrochloric acid, sulfuric acid, aqua regia, concentrated alkali corrosion.
✔ Hiki ke hoʻohana ʻia no ka waiʻakika corrosive a me ka wai paʻakai alkali.
■Polyperfluoroethylene propylene ( F46-FEP )
Loaʻa iā ia ke kūpaʻa kemika maikaʻi a me ke kūʻē ʻana i ka radiation, a me ka non-flammability, nā waiwai uila a me nā mechanical.Ua like kona mau waiwai kemika me ka polytetrafluoroethylene, me ka ikaika compressive a me ka ikaika tensile ʻoi aku ka maikaʻi ma mua o ka polytetrafluoroethylene.
✔ Hiki ke hoʻohana ʻia no ka waiʻakika corrosive a me ka wai paʻakai alkali.
■Copolymer o ka tetrafluoroethylene a me ka perfluorocarbon ma o ka vinyl ether (PFA)
Loaʻa nā waiwai kemika like me ka F46 a ʻoi aku ka ikaika o ka tensile ma mua o F46.
✔Hiki ke hoʻohana ʻia no ka waiʻakika corrosive a me ka wai paʻakai alkali.
