1. Anti-corrosion ea Metal Valve

Li-valve tsa Metal li sirelelitsoe ho senya ka ho li roala ka lesela le sireletsang (pente, pigment, thepa ea ho tlotsa, joalo-joalo) e sireletsang valve ho senya nakong ea tlhahiso, polokelo, lipalangoang le tšebeliso.

Mokhoa oa anticorrosion oa Metal Valve o itšetlehile ka nako e hlokahalang ea tšireletso, maemo a lipalangoang le a ho boloka, litšobotsi tsa kaho ea li-valve le lisebelisoa, ha e le hantle, ho nahana ka phello ea moruo ea ho phahamisa anticorrosion.

Ho na le mekhoa e mene ea mantlha ea ts'ireletso ea kutu bakeng sa Metal Valves le likarolo tsa eona:

1.1 Lokolla volatile corrosion inhibitor moeeng oa mouoane (o koahetsoeng ka pampiri e phunyang, e bululetsoeng ka kamoreng ea lihlahisoa, joalo-joalo).

1.2 Sebelisa litharollo tsa metsi le joala tse koetsoeng.

1.3 Sebelisa lesela le tšesaane la thepa e thibelang ho bola holim'a valve le likarolo tsa eona.

1.4 Sebelisa filimi e koetsoeng kapa filimi ea polymer ka holim'a valve le likarolo tsa eona.

2. Tšebeliso ea Valve ea Lintho

Li-valve tsa maiketsetso li phahametse li-valve tsa tšepe maemong a mangata a senyang, tsa pele ka ho hanyetsa ho bola, tsa bobeli ka boima ba letlooa, 'me matla a tsona a itšetlehile ka sebōpeho, tokisetso le palo ea likhoele tse matlafatsang.(ka kakaretso, ha peresente e kholo ea fiber, e na le matla a mangata a motsoako.)

Lits'ebetsong tsa Valve, boima ba motheo ba fiber bo boemong ba 30% -40%, 'me botsitso ba lik'hemik'hale ba eona bo khethoa haholo-holo ke litšobotsi tsa resin noumenon tsa fiber e kentsoeng sehlahisoa sa ho qetela.Li-valve tsa maiketsetso, 'mele o tiileng oa polymer e ka ba Thermoplastic (joalo ka PVC-polyvinylidene fluoride, PPS-poly(p-phenylene sulfide), joalo-joalo) kapa resin ea thermosetting (joalo ka polyester, ethylene le epoxy, joalo-joalo). .

Thermosetting resin e boloka matla a eona ka mocheso o phahameng ho feta thermoplastic resin (ke hore, resin ea thermosetting e na le mocheso o phahameng oa mocheso).
