1. Nyob rau hauv cov nqe lus ntawm daim ntawv, feem ntau siv roj hmab washers muaj xws li: roj hmab flat washers, roj hmab O-rings, yas tiaj tus ntxhua khaub ncaws, teflon-coated washers, asbestos roj hmab washers, hlau tiaj tus ntxhua khaub ncaws, hlau tshwj xeeb-puab washers, hlau sheath washers, corrugated tshuab ntxhua khaub ncaws, ntxhua khaub ncaws ntxhua khaub ncaws, thiab lwm yam.

Rubber flat washers:

Nws yog ib qho yooj yim rau deform, thiab nws yog ib qho yooj yim mus nias, tab sis lub siab thiab kub kuj tsis zoo, thiab nws tsuas yog siv nyob rau hauv qhov chaw uas lub siab yog tsawg thiab kub tsis siab. Cov roj hmab ntuj muaj qee cov kua qaub thiab alkali tsis kam, thiab kev ua haujlwm kub yuav tsum tsis pub tshaj 60 degree; neoprene roj hmab kuj tiv taus qee cov kua qaub thiab alkalis, thiab kev ua haujlwm kub yog 80 degree; nitrile roj hmab yog roj-resistant thiab siv tau mus txog 80 degree; Cov roj hmab fluorine muaj kev tiv thaiv corrosion zoo thiab tiv taus qhov kub thiab txias kev ua haujlwm kuj muaj zog dua li cov roj hmab dav dav, thiab nws tuaj yeem siv rau hauv nruab nrab ntawm 150 degree.

Roj hmab sealing gasket:

Tus ntoo khaub lig-sectional duab yog ib lub voj voog zoo meej, uas muaj qee yam ntawm tus kheej-tightening nyhuv. Cov nyhuv sealing zoo dua li ntawm lub tshuab ntxhua khaub ncaws, thiab lub zog nias me me.

2. Hais txog cov khoom siv, cov khoom tseem ceeb ntawm cov roj hmab ncoo yog: silicone ncoo, nitrile roj hmab ncoo, fluororubber pads, thiab lwm yam roj hmab ncoo. Cov roj hmab gaskets muaj cov yam ntxwv ntawm cov roj tsis kam, acid thiab alkali tsis kam, txias thiab kub tsis kam, kev laus ua haujlwm, thiab lwm yam, thiab tuaj yeem txiav ncaj qha mus rau hauv ntau hom sealing gaskets, uas yog dav siv hauv tshuaj, hluav taws xob, tshuaj lom neeg kev lag luam, antistatic. , nplaim retardant, zaub mov thiab lwm yam lag luam.

Silicone Roj Hmab:

Nws muaj qhov ua tau zoo ntawm qhov kub thiab txias tsis kam, tswj kev ua haujlwm zoo hauv qhov kub thiab txias ntawm -70 degree rau ntxiv rau 260 degree, tiv taus ozone thiab huab cua, thiab tsim nyog rau sealing gaskets hauv thermal machinery. Nws yog non-toxic thiab siv tau los ua thermal rwb thaiv tsev, rwb thaiv tsev cov khoom thiab cov khoom siv roj hmab kho mob. Nyob rau tib lub sijhawm, nws muaj cov khoom zoo xws li dej tsis zoo, nplaim hluav taws kub, kub tsis kam, hluav taws xob conductivity, hnav tsis kam, roj tsis kam, thiab lwm yam. Nws yog dav siv hauv tshuab, hluav taws xob, kav dej thiab lwm yam lag luam.

Nitrile roj hmab:

NBR (Nitrile-Butadiene Rubber) yog ib qho polymer tsim los ntawm emulsion copolymerization ntawm butadiene thiab acrylonitrile. Nws yog nto moo rau nws zoo heev roj kuj, nrog rau zoo hnav tsis kam, laus kuj thiab huab cua nruj. Yog li ntawd, nws yog dav siv hauv kev lag luam roj hmab.

fluororubber:

Nws muaj qhov kub thiab txias tsis kam, tuaj yeem siv rau hauv ib puag ncig ntawm -20 degree - ntxiv rau 200 degree, thiab muaj zog oxidants, roj, acid thiab alkali. Feem ntau siv nyob rau hauv qhov kub thiab txias, lub tshuab nqus tsev siab thiab siab siab ib puag ncig, tab sis kuj haum rau roj ib puag ncig, dav siv roj av, tshuaj, aviation, aerospace thiab lwm yam departments.

Lwm yam:

Neoprene, roj hmab ntuj, EPDM, acrylate thiab lwm yam roj hmab tshwj xeeb. Nws muaj cov yam ntxwv ntawm cov roj, acid, alkali, hnav tsis kam, siab thiab kub tsis kam.

Txheem rau kev siv roj hmab gasket:

Txhawm rau muab kev ua si tag nrho rau cov yam ntxwv ntawm ntau yam gaskets, cov hauv qab no yuav tsum tau txiav txim siab thaum siv roj hmab gaskets:

1. Nws muaj qhov zoo elasticity thiab rov qab zoo, tuaj yeem hloov kho kom haum rau kev hloov pauv thiab kub hloov pauv, muaj qhov yooj yim tsim nyog, thiab tuaj yeem haum zoo rau qhov chaw sib cuag;

2. Tsis muaj kuab paug rau cov txheej txheem nruab nrab;

3. Tsis muaj hardening ntawm qhov kub thiab txias, me me shrinkage;

4. Kev ua haujlwm zoo, kev teeb tsa yooj yim thiab nias;

5. Tsis muaj nplaum sealing nto, yooj yim rau disassemble.
