Nto moo zoo tshaj plaws Ptfe Piston Rings Supplier - Kev Cai Xim Loj PTFE Washer - Yokey

Paub meej

PTFE nplhaib polytetrafluoroethylene yog ib qho zoo corrosion kuj cov ntaub ntawv nyob rau hauv lub ntiaj teb no niaj hnub no, thiaj li tau txais lub koob npe nrov ntawm "yas huab tais". Nws tuaj yeem siv rau hauv txhua hom tshuaj nruab nrab rau lub sijhawm ntev, thiab nws tau daws ntau yam teeb meem hauv tshuaj lom neeg, roj av, tshuaj thiab lwm yam haujlwm hauv peb lub tebchaws. Ptfe seals, gaskets, gaskets. Polytetrafluoroethylene seals, gaskets, sealing gaskets yog ua los ntawm kev tshem tawm polytetrafluoroethylene resin moulding.

Polytetrafluoroethylene (PTFE) tej yam kev mob ntawm kev siv nyob rau hauv chemical kev lag luam, petrochemical, refining, alkali, acid, phosphate chiv, tshuaj, tshuaj tua kab, tshuaj fiber ntau, zas xim, coking, thee gas, organic synthesis, non-ferrous smelting, steel, atomic zog thiab siab. purity khoom (piv txwv li, ionic membrane electrolysis), viscous khoom thauj thiab kev khiav hauj lwm, nruj heev noj qab haus huv cov zaub mov, dej haus thiab lwm yam ntau lawm departments. Nruab nrab phosphoric acid, sulfuric acid, nitric acid, hydrochloric acid, ntau yam organic acids, organic solvents, muaj zog oxidants thiab lwm yam muaj zog corrosive tshuaj media.

Kub -100 ~ 280 ℃, tso cai rau txias txias thiab cua sov tam sim ntawd, los yog alternating kub thiab txias ua hauj lwm.

Siab -0.1 ~ 6.4mpa (tag nrho tsis zoo siab rau 64kgf / cm2)

-0.1 ~ 6.4mpa (Fullvacuumto64kgf/cm2)

PTFE tuav lub nplhaib yog tsuas yog los ntxiv dag zog rau lub tog raj kheej, hydraulic system lossis valve siab yam tsis poob nws txoj haujlwm sealing, tuaj yeem tiv thaiv O-ring "extrusion", txhim kho nws txoj kev siv siab, nws qhov loj tuaj yeem kho raws li cov neeg siv khoom xav tau.

PTFE tuav lub nplhaib yog kub resistant - khiav hauj lwm kub txog 250 ℃.

PTFE nplhaib tsis kub tsis kam - nrog zoo txhua yam toughness; Txawm tias thaum kub poob rau -196 ℃, 5% elongation tuaj yeem tswj tau.

PTFE tuav lub nplhaib corrosion kuj - rau feem ntau cov tshuaj thiab cov kuab tshuaj, qhia inert, muaj zog acid thiab alkali, dej thiab ntau yam organic solvents.

PTFE nplhaib huab cua tsis kam - yas hauv lub neej laus.

PTFE nplhaib siab lubrication - yog cov khoom siv hauv kev sib txhuam coefficient.

PTFE nplhaib tsis ua raws - nws yog qhov tsawg tshaj plaws ntawm qhov nro hauv cov khoom siv thiab tsis ua raws li cov khoom siv.
