Electromagnetic flowmeter o se meafaigaluega e faʻaogaina ai le mataupu faavae o le faʻaogaina o le eletise e fua ai le tafe o le sua faʻavae e faʻavae i luga o le malosi eletise e faʻaosoina pe a oʻo atu le sua faʻafefe i fafo i fafo.
E faʻapefea la ona filifili le mea e ufiufi ai totonu ma mea eletise?
Filifiliga o Mea e ufiufi ai
■ Neoprene (CR):
O se polymer e faia i le emulsion polymerization o le chloroprene monomer. O lenei mole paʻu o loʻo i ai le chlorine atoms, faʻatusatusa i isi paʻu faʻamoemoe lautele: E sili ona lelei le anti-oxidation, anti-ozone, e le mu-mu, e tineia e le tagata lava ia pe a uma le afi, suauʻu tetee, solvent resistance, acid and alkali resistance, ma le matua. ma le tete'e o kesi. Lelei fufusi ma isi mea lelei.
✔ E fetaui lelei mo le fuaina o le tafe o vai paipa, vai tau pisinisi, vai sami ma isi ala o faasalalauga.
■ Pa'u Polyurethane (PU):
E polymerized e polyester (po'o polyether) ma le diisocyanamide lipid compound. O loʻo i ai le lelei o le maualuga o le maʻaʻa, malosi lelei, maualuga elasticity, maualuga faʻaofuofu teteʻe, loimata tetee, matua tetee, ozone tetee, radiation tetee ma conductivity lelei eletise.
✔ E fetaui lelei mo le fuaina o le tafe o ala o faasalalauga slurry e pei o le pulupulu ma le oa.
■Polytetrafluoroethylene (P4-PTFE)
O se polymer saunia e polymerization o le tetrafluoroethylene o se monomer. White waxy, translucent, vevela vevela, malulu malulu, e mafai ona faʻaaogaina i le -180 ~ 260 ° C umi. O lenei mea o loʻo i ai uiga o le acid ma alkali resistance, teteʻe atu i soʻomea faʻalaʻau eseese, teteʻe i le faʻafefeteina o le hydrochloric acid, sulfuric acid, aqua regia, concentrated alkali corrosion.
✔ E mafai ona faʻaaogaina mo le gaʻo masima ma le alkali masima vai.
■Polyperfluoroethylene propylene ( F46-FEP )
E sili ona lelei le mautu o kemikolo ma le mata'ina o le tete'e atu o le radiation, fa'apea fo'i ma le le mu, lelei eletise ma mea fa'ainisinia. O ona vailaʻau faʻapitoa e tutusa ma le polytetrafluoroethylene, faʻatasi ai ma le malosi faʻamalosi ma le malosi faʻamalosi e sili atu nai lo polytetrafluoroethylene.
✔ E mafai ona faʻaaogaina mo le gaʻo masima ma le alkali masima vai.
■Copolymer o le tetrafluoroethylene ma le perfluorocarbon e ala i le vinyl ether (PFA)
O mea fa'apipi'i mo le mita fa'aeletonika o lo'o i ai mea tau kemikolo tutusa e pei o le F46 ma sili atu le malosi fa'amalosi nai lo le F46.
✔E mafai ona faʻaaogaina mo le gaʻo masima ma le alkali masima vai.
Filifiliga Eletise Mea
| 316L | E fetaui lelei mo otaota fale, otaota fale gaosimea, vai lelei, otaota o taulaga, ma isi, ma vaifofo masima masima vaivai corrosive. |
| Hastelloy (HB) | E talafeagai mo mea e le faʻamaʻi faʻamaʻi e pei ole hydrochloric acid (concentration itiiti ifo i le 10%).
