Gasket feem ntau yog siv hauv cov cuab yeej hluav taws xob, pwm tsim, precision machinery, hardware qhov chaw, mechanical qhov chaw, stamping qhov chaw, hardware manufacturing.
Gasket feem ntau yog siv hauv cov cuab yeej hluav taws xob, pwm tsim, precision machinery, hardware qhov chaw, mechanical qhov chaw, stamping qhov chaw, hardware manufacturing. Gasket tuaj yeem siv los daws cov teeb meem txij nkawm ntawm lub tshuab thaum ntsuas qhov sib txawv ntawm pwm thiab qhov tshwm sim ntawm kev co, swaying thiab instability tshwm sim thaum lub tshuab yog laus. Cov nyhuv sealing ntawm flange kev sib txuas kuj yog ib qho kev siv zoo ntawm cov hlau gaskets.
Non-metallic gasket. Tsis yog-hlau gaskets yog mos, corrosion-resistant thiab pheej yig, tab sis tsis zoo kub thiab siab tsis kam. Nws yog siv rau flange sealing ntawm nruab nrab thiab qis cov hlab ntsha los yog cov kav dej ntawm qhov kub thiab txias. Cov khoom siv tsis yog xim hlau muaj xws li roj hmab gaskets, asbestos gaskets, asbestos roj hmab gaskets, saj zawg zog graphite gaskets thiab polytetrafluoroethylene gaskets.
① Roj hmab phaj. Cov ntaub ntawv tseem ceeb rau kev ua cov roj hmab gasket yog cov roj hmab ntuj, roj hmab nitrile, cov roj hmab neoprene, thiab lwm yam. Tsis tas li ntawd, fluorine roj hmab thiab lwm yam roj hmab tshwj xeeb kuj tau pib siv. Roj Hmab tau siv dav hauv kev sib khi ntawm cov thawv ntim khoom thiab cov raj xa khoom, yooj yim rau kev siv ntau, yooj yim, tab sis nws tsis muaj kev tiv thaiv siab, yooj yim rau yaj thiab nthuav dav hauv cov roj ntxhia thiab tsis xeb, yooj yim rau hnub nyoog ntawm qhov kub thiab txias, poob resilience.
② Asbestos. Cov ntaub ntawv asbestos yog ntub asbestos thiab xiav asbestos. ntub asbestos muaj cua sov zoo thiab alkaline tsis kam, siab tensile lub zog thiab tsis zoo acid kuj. Feem ntau cov ntaub ntawv asbestos yog ua los ntawm nws. Xiav asbestos tsis tsuas yog muaj cov cua kub zoo, tab sis kuj zoo acid kuj, yog li nws yog feem ntau siv rau hauv kev tsim cov kua qaub-resistant asbestos roj hmab los xij. Qhov kev khiav hauj lwm kub ntawm asbestos board yog qis dua 550 degrees. Asbestos daim kab xev los yog hlua tuaj yeem siv rau cov hlab ntsha loj uas tsis muaj zog. Thaum siv asbestos hlua, nws feem ntau yog impregnated nrog sodium silicate. Cov kua qaub, alkali cov kuab tshuaj thiab lwm yam xov xwm kuj tseem siv tau cov gaskets.
③ Asbestos roj hmab ntawv. Asbestos roj hmab ntawv yog ua los ntawm asbestos, roj hmab thiab muab tub lim. General asbestos fiber account rau 60 -85 feem pua . Raws li nws cov txheej txheem kev faib tawm, kev ua tau zoo thiab kev siv, feem ntau yog siab siab asbestos roj hmab board, nruab nrab thiab qis siab asbestos roj hmab board thiab roj resistant asbestos roj hmab board. Asbestos roj hmab phaj muaj lub zog tsim nyog, elasticity, softness thiab lwm yam khoom, nws yog qhov yooj yim thiab pheej yig los ua cov gaskets, yog li nws tau nce sai thiab siv hauv kev lag luam tshuaj.
④ Saj zawg zog graphite. Saj zawg zog graphite yog ib yam tshiab sealing khoom, zoo resilience, softness, kub tsis kam, tau ceev ceev thiab siv nyob rau hauv cov lag luam tshuaj.
⑤ Polytetrafluoroethylene (PTFE luv luv). Polytetrafluoroethylene tshuaj tiv thaiv, kub tsis kam, txias tsis kam, roj kuj yog superior rau yas, nws tsis yooj yim rau laus, tsis muaj combustion, dej nqus yuav luag xoom. Nws cov koom haum tuab, tsis muaj-polar molecular qauv, siv los ua gasket, lub rooj sib chwv tau yuav yog tus, cov flange flange tsis lo. Ntxiv rau qhov raug corroded los ntawm molten alkali hlau thiab fluorine uas muaj cov pa roj carbon monoxide, nws tuaj yeem tiv thaiv corrosion ntawm ntau yam kua qaub, alkali, ntsev thiab roj tov tawm.
