Cov txheej txheem tsim khoom ntawm fluororubber gaskets pib nrog kev xaiv thiab tsim cov khoom siv raw. Fluororubber, raws li cov khoom siv tseem ceeb, muaj cov fluorine atoms hauv nws cov qauv molecular, ib qho khoom siv uas muab cov khoom siv rau qhov kub thiab txias thiab tshuaj corrosion. Cov neeg tsim khoom yuav tsum tswj hwm qhov sib npaug ntawm cov khoom siv raw, sib tov lub hauv paus fluororubber nrog cov fillers, vulcanizing agents, kev pab, thiab lwm yam ntaub ntawv pab raws li ib tug predetermined piv. Lub hauv paus tseem ceeb ntawm cov kauj ruam no yog ua kom ntseeg tau tias qhov kev faib tawm tsis sib xws ntawm txhua qhov sib xyaw, kom tsis txhob muaj qhov tsis xws luag hauv kev ua haujlwm tom ntej vim qhov sib xyaw tsis sib xws.
Tom qab sib tov, cov ntaub ntawv raw nkag mus rau hauv cov txheej txheem compounding. Cov khoom siv sib xyaw siv cov tshuab txiav thiab cov cua sov kom ua tiav cov roj hmab nrog ntau yam khoom ntxiv, ua kom muaj kev sib xyaw ua ke. Kev tswj kub thiab lub sijhawm yog qhov tseem ceeb hauv cov txheej txheem no; Kev kub siab heev tuaj yeem ua rau vulcanization ntxov ntxov, thaum kub qis heev tuaj yeem ua rau tsis txaus sib xyaw. Cov roj hmab compounded yuav tsum tau txias thiab tso cai rau sawv ntsug kom tso tawm sab hauv kev ntxhov siab thiab ruaj khov ntawm cov khoom siv.
Tom ntej no yog lub preforming theem. Cov roj hmab sib xyaw ua tiav rau hauv ib nrab- cov khoom tiav, xws li cov nplooj ntawv lossis cov strips, siv cov khoom siv extrusion lossis calendering, mus txog qhov zoo ntawm cov khoom kawg. Pre-forming tsis yog tsuas yog rau qhov pib shaping tab sis kuj yog lub hom phiaj los tshem tawm cov huab cua npuas uas yuav muaj nyob rau hauv cov roj hmab compound, kom ntseeg tau cov khoom ceev. Qee lub tuam txhab siv cov cuab yeej ntsuas ntsuas qhov tseeb ntawm theem no los tswj qhov tseeb qhov tseeb ntawm ib nrab- cov khoom tiav thiab txo cov khoom pov tseg hauv kev ua haujlwm tom ntej.
Vulcanization yog ib kauj ruam tseem ceeb hauv kev tsim cov fluororubber gaskets. Lub pre-cov roj hmab sib xyaw ua ke yog muab tso rau hauv pwm thiab ua kom sov hauv qhov kub thiab txias. Thaum lub sij hawm vulcanization, tus ntoo khaub lig- txuas cov ntaub ntawv sib txuas ntawm cov roj hmab molecules, thiab cov khoom hloov pauv los ntawm lub xeev yas mus rau lub xeev elastic, yog li tau txais cov khoom tsim nyog thiab tshuaj lom neeg ruaj khov. Lub vulcanization tej yam kev mob yuav tsum tau precisely kho raws li cov khoom thickness, formulation muaj pes tsawg leeg, thiab kev ua tau zoo yuav tsum tau. Lub sij hawm tsis txaus tuaj yeem ua rau qhov tsis tiav - txuas, thaum lub sij hawm ntau dhau yuav ua rau cov khoom laus.
