Cov txheej txheem tseem ceeb ntawm cov khoom siv roj hmab
Nws
Txhawm rau hloov mus rau ntau yam kev siv, tau txais ntau yam khoom, thiab txhawm rau txhim kho kev ua haujlwm ntawm cov khoom siv roj hmab thiab txo cov nqi, cov khoom sib txawv sib txawv yuav tsum tau ntxiv rau cov roj hmab nyoos. Kev sib xyaw yog ib txoj hauv kev uas cov roj hmab yas yas yog tov nrog cov khoom sib xyaw ua ke, muab tso rau hauv cov roj hmab sib xyaw tshuab, thiab cov khoom sib xyaw ua ke yog tag nrho thiab sib xyaw ua ke hauv cov roj hmab nyoos los ntawm kev sib xyaw ua ke. Kev sib tov yog ib qho tseem ceeb hauv kev tsim cov khoom siv roj hmab. Yog tias qhov sib tov tsis sib xws, lub luag haujlwm ntawm cov roj hmab thiab cov khoom sib xyaw ua ke yuav tsis siv tag nrho, uas yuav cuam tshuam rau kev ua haujlwm ntawm cov khoom. Cov roj hmab sib xyaw tau txais tom qab sib tov yog hu ua roj hmab compound. Nws yog cov khoom siv ua tiav rau kev tsim khoom ntawm ntau yam khoom siv roj hmab, feem ntau hu ua roj hmab compound, thiab feem ntau yog muag raws li cov khoom lag luam. Xav tau cov khoom siv roj hmab. Raws li cov qauv sib txawv, muaj ntau qib sib txawv thiab ntau yam ntawm cov roj hmab sib xyaw nrog cov khoom sib txawv, thiab cov kev xaiv muaj.
Txoj kev
Nyob rau hauv cov txheej txheem ntawm cov khoom siv roj hmab, lub calender lossis extruder yog siv los ua cov txheej txheem ntawm ntau yam duab thiab ntau thiab tsawg, uas yog hu ua molding. Cov txheej txheem forming yog:
Calendering yog tsim rau kev tsim cov ntawv yooj yim thiab phaj khoom. Nws yog ib txoj hauv kev los nias cov roj hmab sib xyaw rau hauv ib zaj duab xis ntawm ib qho duab thiab ib qho me me los ntawm lub calender, hu ua calendering. Qee cov ntaub ntawv fiber ntau siv hauv cov khoom siv roj hmab (xws li log tsheb, daim ntaub roj hmab, hoses, thiab lwm yam) yuav tsum tau coated nrog ib txheej nyias ntawm cov kua nplaum (gluing ntawm cov fiber ntau kuj hu ua kua nplaum los yog txhuam), thiab cov txheej txheem gluing feem ntau ua tiav. ntawm lub calender. Cov khoom siv fiber ntau yuav tsum tau qhuav thiab dipped ua ntej calendering. Lub hom phiaj ntawm kev ziab yog txo qis cov dej noo ntawm cov khoom siv fiber ntau (kom tiv thaiv dej los ntawm evaporating thiab foaming) thiab ua kom kub ntawm cov khoom fiber ntau kom ntseeg tau qhov zoo ntawm cov txheej txheem calendering. Glue dipping yog txheej txheem tsim nyog ua ntej gluing, thiab lub hom phiaj yog txhawm rau txhim kho kev sib raug zoo ntawm cov ntaub ntawv fiber ntau thiab cov khoom siv roj hmab.
Extrusion molding yog siv rau cov khoom siv roj hmab ntau dua, xws li cov log tsheb treads, cov raj roj hmab, thiab cov hlau hlau saum npoo txheej uas yuav tsum tau tsim los ntawm txoj kev extrusion molding. Nws yog ib txoj hauv kev uas cov roj hmab sib txuas nrog qee qhov ntawm cov yas yog muab tso rau hauv lub hopper ntawm extruder, thiab nyob rau hauv lub extrusion ntawm ib tug ntsia hlau, nws yog ib txoj kev ntawm nruam molding los ntawm ntau lub qhov ncauj duab (tseem hu ua templates). . Ua ntej extruding, cov khoom siv roj hmab yuav tsum tau preheated kom cov khoom siv roj hmab muag muag thiab yooj yim rau extrude, thiaj li yuav tau txais cov khoom siv roj hmab nrog du nto thiab qhov loj me.
Compression molding tseem tuaj yeem siv los tsim qee cov duab nyuaj (xws li khob, sealing rings) cov khoom siv roj hmab, nrog kev pab los ntawm cov poj niam thiab txiv neej pwm pwm, cov khoom siv roj hmab tau muab tso rau hauv pwm rau cua sov thiab tsim.
Vulcanization
Cov txheej txheem ntawm kev hloov cov roj hmab yas rau hauv cov roj hmab elastic hu ua vulcanization. Nws yog txhawm rau ntxiv qee tus nqi ntawm vulcanizing tus neeg sawv cev (xws li leej faj, vulcanization accelerator, thiab lwm yam) rau cov khoom lag luam ib nrab ua los ntawm cov roj hmab nyoos (ua hauv lub tank vulcanizing). Thaum tshav kub kub thiab ua kom sov ntawm qhov kub thiab txias, yog li ntawd cov kab hluav taws xob ntawm cov roj hmab nyoos tau sib txuas mus rau hauv peb qhov kev sib txuas network los ntawm kev tsim ntawm" sulfur txuas hniav", yog li tig cov roj hmab yas rau hauv ib tug vulcanized roj hmab nrog siab elasticity. Txij li thaum lub cross-linking daim ntawv cog lus yog tsim los ntawm leej faj, nws yog hu ua" vulcanization". Nrog rau txoj kev loj hlob sai ntawm cov roj hmab hluavtaws, tam sim no muaj ntau ntau yam ntawm vulcanizing agents, ntxiv rau sulfur, muaj cov organic polysulfides, peroxides, hlau oxides thiab lwm yam. Yog li ntawd, txhua tus txheej txheem uas tuaj yeem hloov pauv cov qauv ntawm cov roj hmab yas rau hauv peb-dimensional network qauv ntawm cov roj hmab elastic hu ua vulcanization, thiab txhua yam khoom uas tuaj yeem ua raws li" bridging" hauv cov khoom siv roj hmab hu ua" vulcanizing tus neeg sawv cev."
Cov roj hmab vulcanized yog hu ua vulcanized roj hmab, tseem hu ua roj hmab muag, feem ntau hu ua" roj hmab". Vulcanization yog ib qho ntawm cov txheej txheem tseem ceeb tshaj plaws hauv kev ua cov roj hmab, thiab ntau yam khoom siv roj hmab yuav tsum tau vulcanized kom tau txais kev ua tau zoo. Cov roj hmab unvulcanized tsis muaj nqi hauv kev siv, tab sis nyob rau hauv-sulfur (lub degree ntawm vulcanization tsis txaus, lub sij hawm vulcanization tsis txaus, thiab lub xeev zoo tshaj yog tsis mus txog) thiab tshaj-sulfur (lub sij hawm vulcanization yog tshaj, kev ua tau zoo. yog txo qis), ob qho tib si ua rau cov roj hmab Performance poob. Yog li ntawd, lub sij hawm vulcanization yuav tsum tau tswj nruj me ntsis thaum lub sij hawm tsim cov txheej txheem los xyuas kom meej tias cov vulcanized roj hmab cov khoom muaj kev ua tau zoo tshaj plaws thiab lub neej ntev kev pab cuam.
