Daim kab xev kaw tsheb (Qhov rooj, qhov rai, lub qab nthab)
Daim kab xev kaw tsheb
Daim kab xev kaw tsheb yog ib qho tseem ceeb, siv dav hauv qhov rooj, qhov rai, lub cev tsheb, lub qab nthab, lub thawv cav thiab lub thawv khaws cia (lub hnab nqa khoom) thiab lwm yam, nrog rau kev rwb thaiv suab, tiv thaiv plua plav, tiv thaiv dej thiab ua kom noo noo, khaws thiab tswj qhov chaw me me hauv lub tsheb, ua si tus neeg nyob hauv lub tsheb, cov khoom siv hluav taws xob thiab cov khoom siv kho tshuab thiab cov khoom siv tiv thaiv tseem ceeb. Nrog rau kev txhim kho ntawm kev lag luam tsheb, qhov tseem ceeb ntawm kev zoo nkauj, kev tiv thaiv ib puag ncig thiab kev ua haujlwm xis nyob ntawm daim kab xev kaw tau dhau los ua qhov tseem ceeb. Lub kaw lus kaw (automomo-bile SEALING SYSTEM) tau teeb tsa rau ntau qhov chaw ntawm lub tsheb tau raug tshawb fawb tshwj xeeb thiab tsim hauv kev lag luam tsheb txawv teb chaws, thiab nws qhov tseem ceeb tau nyiam kev mloog ntxiv. 1. Raws li lub npe ntawm cov khoom kaw (qhov chaw), kev faib tawm suav nrog: lub cav lub kaus mom foob, thiab tuaj yeem faib ua pem hauv ntej, sab thiab tom qab; LUB QHOV ROOJ KAW; LUB QHOV RAIS rau lub qhov rais cua pem hauv ntej thiab tom qab; LUB qhov rais kaw sab (Lub qhov rais kaw sab); LUB QHOV RAIS SUNROOF; LUB QHOV RAIS PRIMARY; Daim kab xev kaw ntawm lub qhov rais qhia qhov (GLASSRUN CHANNEL); Cov kab sab hauv thiab sab nraud (dej txiav) (WAISTLINE); LUB TSEV LUB NRES; Cov kab kaw tiv thaiv suab nrov; Xws li tiv thaiv plua plav. 2. Raws li cov yam ntxwv ntawm SEALING, nws tuaj yeem muab faib ua WEATHERSTRIP foob thiab foob dav dav. Ntawm lawv, cov kab kaw huab cua muaj lub raj dej npuas hollow, uas muaj kev ua haujlwm zoo dua rau qhov kub thiab txias thiab av noo. Cov kab kaw huab cua feem ntau siv suav nrog cov kab kaw lub qhov rooj, cov kab kaw lub hnab, cov kab npog lub cav, thiab lwm yam. Cov kab kaw dav dav siv yog cov kab kaw qhov rai pem hauv ntej thiab tom qab thiab cov kab kaw qhov rai ces kaum, cov kab sab hauv thiab sab nraud, thiab lwm yam. 3. Raws li kev faib tawm cov qauv sib xyaw ntawm cov khoom siv roj hmab, nws tuaj yeem muab faib ua cov kab kaw roj hmab ntshiab - ua los ntawm ib qho roj hmab; Ob daim kab kaw sib xyaw - ua los ntawm cov kua nplaum ntom ntom thiab cov kua nplaum ua npuas ncauj, feem ntau nyob rau hauv cov kua nplaum ntom ntom hauv qhov kev taw qhia ntawm lub axis uas muaj cov khoom siv hlau; Peb lub foob sib xyaw - muaj ob hom sealant (ib qho yog xim dawb) thiab daim kab kaw sponge, feem ntau muaj cov hlau pob txha thiab cov fibers txhawb nqa hauv cov sealant. Plaub daim kab xev sib xyaw ua ke - Shanghai Shenya Sealing parts Co., Ltd. tau ua tus thawj coj hauv kev tsim thiab tsim cov kab xev sib xyaw ua ke uas muaj 4 hom roj hmab, nyob rau hauv qhov chaw roj hmab (lub raj npuas) thiab npog nrog ib txheej nyias ntawm cov nplaum tiv thaiv, yog li txhim kho lub neej ua haujlwm ntawm cov foob. 4. Raws li hom khoom siv faib tawm, tuaj yeem muab faib ua cov kab xev roj hmab; Cov kab xev yas; Cov kab xev thermoplastic elastomer. 5. Faib tawm raws li lub xeev kho qhov chaw, qee qhov chaw ntawm cov kab xev tom qab kev kho ntxiv, tuaj yeem muab faib ua cov kab xev flocking; Cov kab xev txheej saum npoo; Muaj cov kab xev ntaub. 6. Kev faib tawm tshwj xeeb, qee qhov chaw muaj kev ua haujlwm ntse hauv hluav taws xob, xws li cov kab xev tiv thaiv clamping.
(2) cov khoom siv ntawm daim kab xev sealing
Cov roj hmab epdm
Ethylene propylene diene diene (EPDM) yog synthesized los ntawm polymerization ntawm ethylene thiab propylene monomers nrog me ntsis ntawm cov diolefin tsis-conjugated. Cov qauv ntawm cov polymer yog tus cwj pwm los ntawm unsaturated ob chav bonds hauv cov saw tseem ceeb thiab unsaturated ob chav bonds hauv cov saw ceg. Yog li ntawd, nws muaj kev tiv thaiv huab cua zoo heev, tiv thaiv cua sov, tiv thaiv ozone, tiv thaiv uv linear nrog rau kev ua haujlwm zoo thiab qis compression tas mus li deformation, yog li nws yog cov khoom siv nyiam rau kev tsim cov sealing strips. Tam sim no, feem ntau ntawm cov ntaub ntawv sealing strips tsheb siv EPDM ua cov khoom siv tseem ceeb. Raws li cov khoom sib txawv thiab kev ua haujlwm ntawm cov sealing strips, hauv kev siv tiag tiag, vulcanization, kev tiv thaiv, kev txhawb nqa, cov ntaub ntawv operating system thiab cov ntaub ntawv tshwj xeeb (xws li colorant, foaming agent) raug ntxiv rau EPDM cov ntaub ntawv los ua cov nplaum ntom ntom (xws li cov nplaum dub thiab cov nplaum xim) thiab cov nplaum daim txhuam cev. Cov ntaub thaiv qhov rooj tsheb feem ntau yog ua los ntawm cov khoom siv zoo elasticity thiab tiv taus kev hloov pauv compression, tiv taus kev laus, tiv taus ozone, tshuaj lom neeg ua haujlwm, ntau yam kub (-40 ℃ ~ + 120 ℃) EPDM roj hmab ua npuas ncauj thiab cov khoom sib xyaw ua ke, muaj cov khoom siv hlau tshwj xeeb thiab tus nplaig buckle, ruaj khov, yooj yim rau nruab. Nws tau ntev los sib tw nrog cov tuam txhab tsim tsheb loj.

Roj hmab ntuj
Roj hmab ntuj yog ib hom polyisoprene ua lub ntsiab tseem ceeb ntawm cov tshuaj polymer ntuj, cov mis molecular yog (C5H8) N, 91% ~ 94% ntawm nws cov khoom yog roj hmab hydrocarbon (polyisoprene), tus so yog protein, fatty acid, tshauv, qab zib thiab lwm yam khoom tsis yog roj hmab. Roj hmab ntuj yog cov roj hmab dav dav siv ntau tshaj plaws. Vim tias roj hmab ntuj muaj ntau yam ntxwv ntawm lub cev thiab tshuaj, tshwj xeeb tshaj yog nws lub zog zoo heev, rwb thaiv tsev, dej cais thiab plasticity thiab lwm yam ntxwv, thiab, tom qab kev kho mob tsim nyog, kuj muaj roj, acid, alkali, kub, txias, siab, hnav tsis kam thiab lwm yam khoom muaj nqis, yog li, muaj ntau yam kev siv. Piv txwv li, kev siv txhua hnub ntawm khau nag, hnab dej sov, elastic; hnab looj tes phais, cov hlab ntshav, hnab looj tes siv hauv kev kho mob thiab kev noj qab haus huv; Txhua yam log tsheb siv hauv kev thauj mus los; siv txoj siv conveyor, siv txoj siv thauj mus los, hnab looj tes tiv taus acid thiab alkali rau kev siv hauv kev lag luam; siv ua liaj ua teb rau cov kav dej thiab dej ntws, hnab ammonia; cov npas suab rau kev soj ntsuam huab cua; cov khoom siv sealing thiab shockproof rau kev sim tshawb fawb; Cov dav hlau, cov tank, cov phom loj thiab cov npog roj siv rau hauv kev tiv thaiv; Txawm tias cov foob pob hluav taws, cov satellites ntiaj teb cuav thiab cov spacecraft thiab lwm yam khoom siv tshawb fawb thiab thev naus laus zis zoo heev kuj tsis sib cais los ntawm cov roj hmab ntuj. Tam sim no, muaj ntau dua 70,000 yam khoom hauv ntiaj teb ua ib feem lossis tag nrho los ntawm cov roj hmab ntuj. Thermoplastic Vulcanizate (Thermoplastic Vulcanizate), hu ua TPV
1, zoo elasticity thiab compression deformation tsis kam, tiv taus ib puag ncig, tiv taus kev laus sib npaug rau epDM roj hmab, tib lub sijhawm nws tsis kam roj thiab tsis kam rau cov kuab tshuaj thiab neoprene dav dav zoo sib xws. 2, ntau yam kev siv kub (-60-150 ℃), ntau yam kev siv mos thiab tawv (25A - 54D), qhov zoo ntawm kev yooj yim dyeing zoo heev txhim kho kev ywj pheej ntawm kev tsim khoom. 3, kev ua tau zoo heev: muaj kev txhaj tshuaj, extrusion thiab lwm yam thermoplastic ua tiav txoj kev ua tiav, ua haujlwm tau zoo, yooj yim, tsis tas yuav ntxiv cov khoom siv, ua kua ntau, tus nqi shrinkage me me. 4, kev tiv thaiv ib puag ncig ntsuab, rov ua dua tshiab, thiab siv rov qab rau zaug yam tsis muaj kev poob qis tseem ceeb, ua raws li EU ib puag ncig cov cai. 5, qhov hnyav tshwj xeeb yog lub teeb (0.90 - 0.97), qhov zoo ntawm qhov tsos yog sib xws, qib nto yog siab, qhov xav zoo. Raws li cov yam ntxwv kev ua tau zoo saum toj no, TPV yog siv dav hauv ntau yam kev siv nrog cov khoom siv roj hmab ib txwm muaj. Tam sim no, qee cov khoom ntawm lub tsheb sealing strip yog hloov los ntawm TPV ntawm thermoplastic vulcanized roj hmab nrog EPDM. TPV ntawm cov roj hmab thermoplastic vulcanized muaj qee qhov zoo dua lwm txoj hauv kev hauv kev ua tau zoo thiab tus nqi tag nrho.
