Valve ya Mpira
0102030405
Kuwotcherera Socket PVDF True Union Ball Valve yokhala ndi FPM O-mphete PTEF Mpando
Kodi valve ya PVDF ndi chiyani?
Vavu ya PVDF ndi mtundu wa vavu wopangidwa ndi zinthu za polyvinylidene fluoride (PVDF). PVDF ndi mtundu wa zinthu polima ndi kukana kwambiri mankhwala, kutentha kukana, makutidwe ndi okosijeni kukana, ultraviolet kukana ndi abrasion kukana, etc. Amagwiritsidwa ntchito m'madera osiyanasiyana mafakitale ndi boma. M'munda wa mavavu, mavavu a PVDF nthawi zambiri amagwiritsidwa ntchito potengera sing'anga yowononga, sing'anga yotentha kwambiri komanso sing'anga yokhala ndi tinthu.
Kodi valavu ya PVDF ndi yotani?
PVDF ndi mtundu wa fluoroplastic wokhala ndi kukhazikika kwamankhwala abwino kwambiri, kukana kwanyengo, kukana kwa abrasion ndi kukana kukalamba, komwe kumatha kukhalabe ndikuchita bwino pakutentha kwakukulu. Makamaka, zinthu za PVDF zili ndi izi.
Kukhazikika kwa Chemical:
PVDF imalimbana ndi mankhwala ndipo imatha kukana zinthu zambiri zowononga monga ma acid, alkalis, mchere ndi zosungunulira organic.
Nkhaniyi ili ndi zotsatirazi
Kukana kutentha kwakukulu:
Kusungunuka kwa zinthu za PVDF ndi pafupifupi 170 ℃, zomwe zimatha kugwira ntchito bwino kutentha kwambiri.
Kukana kwa okosijeni:
PVDF zakuthupi si zophweka oxidize pa kutentha kwambiri, ndipo akhoza kusunga makina ake katundu kwa nthawi yaitali.
Abrasion resistance:
Kukana kwa abrasion kwa PVDF ndikwabwinoko kuposa mapulasitiki ambiri aumisiri, kumatha kukhala kosalala kwa nthawi yayitali.
Kukana kukalamba:
PVDF zakuthupi ndizosavuta kukalamba pansi pa cheza cha ultraviolet, ndipo zimatha kusunga mawonekedwe ake kwa nthawi yayitali.
Ubwino wa vavu ya PVDF ndi chiyani?
Monga zinthu za PVDF zili ndi zabwino zomwe zili pamwambapa, valavu ya PVDF ilinso ndi zotsatirazi.
Kulimbana ndi corrosion:
Mavavu a PVDF amatha kukana ma acid ambiri, alkalis, mchere ndi zosungunulira za organic ndi zina zowononga, zomwe zimayenera kuthandizidwa ndi mankhwala osiyanasiyana a Corrosive media.
Kutentha kwambiri:
Mavavu a PVDF amatha kukhala ndi magwiridwe antchito abwino pakutentha kwambiri, koyenera kukonzedwanso kwapamwamba kwambiri.
abrasion resistance:
PVDF mavavu kuvala kukana ndi bwino kuposa mapulasitiki ambiri uinjiniya, mukhoza kusunga pamwamba yosalala kwa nthawi yaitali, si kophweka
Kukana kuwonongeka kwa ukalamba:
PVDF mavavu mu cheza ultraviolet si kophweka kukalamba, akhoza kukhalabe thupi lake kwa nthawi yaitali.
Ukhondo ndi ukhondo:
Mavavu a PVDF ndi osavuta kuyeretsa, angagwiritsidwe ntchito muzakudya, mankhwala ndi madera ena ofunikira ukhondo.
Moyo wautali wautumiki:
Chifukwa mavavu a PVDF ali ndi zida zabwino kwambiri komanso njira zopangira, moyo wake wautali wautumiki, mutha kupulumutsa mtengo wosinthira valavu ndi nthawi.
