Automotive sealing sawb (Qhov rooj, qhov rai, skylight)
Tsheb sealing sawb
Automotive sealing sawb yog ib qho tseem ceeb, dav siv nyob rau hauv lub qhov rooj, qhov rais, lub tsheb lub cev, skylight, cav rooj thiab cia (lub nra) lub thawv thiab lwm yam, nrog suab rwb thaiv tsev, plua plav pov thawj, waterproof thiab damping muaj nuj nqi, khaws cia thiab tuav lub me me. ib puag ncig hauv lub tsheb, ua si rau cov neeg nyob hauv lub tsheb, cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob thiab cov khoom tseem ceeb ntawm kev tiv thaiv. Nrog rau txoj kev loj hlob ntawm kev lag luam tsheb, qhov tseem ceeb ntawm qhov zoo nkauj, kev tiv thaiv ib puag ncig thiab kev ua haujlwm zoo ntawm kev sib khi sawb yog qhov tseem ceeb. Lub SEALING SYSTEM (automo-bile SEALING SYSTEM) tau teeb tsa nyob rau hauv ntau qhov chaw ntawm lub tsheb tau tshwj xeeb tshawb fawb thiab tsim nyob rau hauv kev lag luam tsheb txawv teb chaws, thiab nws qhov tseem ceeb yog ua kom muaj kev nyiam. 1. Raws li lub npe ntawm lub sealing qhov chaw (qhov), cov kev faib muaj xws li: cav HOOD foob, thiab muab faib ua rau pem hauv ntej, sab thiab nram qab; LUB SIJ HAWM; WINDOW cov ntxaij vab tshaus rau pem hauv ntej thiab nram qab cua Windows; SIDE qhov rai foob (SIDE Window foob); SUNROOF foob; PRIMARY DOOR SEAL; Sealing sawb ntawm qhov rais qhia zawj (GLASSRUN CHANNEL); Sab hauv thiab sab nrauv (dej txiav) (WAISTLINE); TRUNK SEAL; Anti-suab nrov sealing sawb; Xws li cov plua plav tiv thaiv. 2. Raws li SEALING cov yam ntxwv, nws tuaj yeem muab faib ua WEATHERSTRIP foob thiab kev foob dav dav. Ntawm lawv, huab cua sealing sawb yog nruab nrog hollow sponge npuas raj, uas muaj qhov kub thiab av noo zoo ua haujlwm. Feem ntau siv huab cua sealing strips muaj xws li lub qhov rooj thav duab sealing sawb, lub hnab ntim lub hnab ntim lub hnab, lub cav npog npog sawb, thiab lwm yam. Feem ntau siv cov sealing strips yog pem hauv ntej thiab nram qab lub qhov rais sealing strips thiab kaum qhov rais sealing strips, sab hauv thiab sab nrauv strips, thiab lwm yam. 3. Raws li rau cov qauv kev faib tawm ntawm cov khoom siv roj hmab, nws tuaj yeem muab faib ua cov roj hmab ntshiab sealing sawb - tsim los ntawm ib qho roj hmab; Ob qho kev sib xyaw sib xyaw sawb kab txaij - tsim los ntawm cov kua nplaum tuab thiab ua npuas dej kua nplaum, feem ntau hauv cov kua nplaum tuab hauv cov axis uas muaj hlau pob txha pob txha tshuab; Triple composite seal - muaj ob hom sealant (ib yam uas yog xim xim) thiab daim txhuam cev sealant, feem ntau muaj cov pob txha hlau thiab cov fibers ntxiv rau hauv lub sealant. Plaub lub sealing sawb - Shanghai Shenya Sealing qhov chaw Co., Ltd. coj tus thawj coj nyob rau hauv txoj kev loj hlob thiab zus tau tej cov composite sealing sawb muaj li ntawm 4 hom roj hmab cov ntaub ntawv, nyob rau hauv cov roj hmab ( npuas raj) nto thiab them nrog ib tug nyias txheej ntawm tiv thaiv txheej nplaum, thiaj li mus ntxiv txhim kho kev pab cuam lub neej ntawm cov ntsaws ruaj ruaj. 4. Raws li hom kev faib khoom, tuaj yeem muab faib ua roj hmab sealing sawb; Yas sealing sawb; Thermoplastic elastomer foob sawb. 5. Muab faib raws li lub xeev kev kho deg, ib co sealing strip nto tom qab kev kho mob ntxiv, tuaj yeem muab faib ua flocking sealing strip; Nto txheej sealing sawb; Muaj cov ntaub thaiv npog. 6. Kev faib ua haujlwm tshwj xeeb, qee qhov sib khi sawb muaj cov khoom siv hluav taws xob ntse, xws li los tiv thaiv cov hlua khi hlua khi.
(2) cov khoom ntawm sealing sawb
Epdm roj hmab
Ethylene propylene diene diene (EPDM) yog synthesized los ntawm polymerization ntawm ethylene thiab propylene monomers nrog ib tug me me ntawm tsis-conjugated diolefin. Cov qauv ntawm cov polymer yog tus yam ntxwv los ntawm unsaturated ob daim ntawv cog lus nyob rau hauv lub ntsiab saw thiab unsaturated ob daim ntawv cog lus nyob rau hauv ceg saw. Yog li ntawd, nws muaj cov huab cua tsis zoo, tiv thaiv tshav kub, tiv thaiv ozone, uv kuj linear nrog rau kev ua haujlwm zoo thiab tsis tshua muaj compression mus tas li deformation, yog li nws yog cov khoom siv rau kev tsim cov sealing strips. Tam sim no, feem ntau ntawm cov khoom siv tsheb sib khi yog siv EPDM ua cov khoom siv tseem ceeb. Raws li cov khoom sib txawv thiab kev ua haujlwm ntawm cov hlua khi, hauv kev siv tswv yim, vulcanization, kev tiv thaiv, kev txhawb zog, cov ntaub ntawv kev khiav hauj lwm thiab cov khoom siv tshwj xeeb (xws li cov xim pleev xim, foaming agent) tau ntxiv rau EPDM cov ntaub ntawv los tsim cov nplaum nplaum (xws li cov nplaum dub. thiab xim nplaum) thiab daim txhuam cev nplaum. Automotive sealing strip feem ntau yog tsim nyog ntawm kev ua npuas dej zoo, kev ua npuas dej ntau ntxiv (-120 ℃) EPDM roj hmab ua npuas dej thiab ntom nti, muaj ib qho kev sib txawv hlau thiab tus nplaig buckle, ruaj, yooj yim rau nruab. Nws tau ntev tau txuam nrog cov tuam txhab tsheb loj.

Ntuj roj hmab
Cov roj hmab ntuj yog ib hom polyisoprene uas yog cov khoom tseem ceeb ntawm natural polymer compound, molecular mis 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 uas tsis yog roj hmab. Cov roj hmab ntuj yog cov khoom siv dav dav siv roj hmab. Vim tias cov roj hmab ntuj muaj cov yam ntxwv ntawm lub cev thiab tshuaj lom neeg, tshwj xeeb tshaj yog nws txoj kev ua haujlwm zoo, rwb thaiv tsev, kev sib cais dej thiab plasticity thiab lwm yam ntxwv, thiab, tom qab kev kho kom tsim nyog, kuj muaj roj kuj, acid tsis kam, alkali tsis kam, kub tsis kam, txias tsis kam, siab tsis kam, hnav tsis kam thiab lwm yam khoom muaj txiaj ntsig, yog li, muaj ntau yam kev siv. Piv txwv li, niaj hnub siv los nag khau, hnab dej sov, elastic; Cov hnab looj tes, cov hlab ntshav, cov hnab looj tes siv hauv kev kho mob thiab kev noj qab haus huv; Txhua yam log tsheb siv hauv kev thauj mus los; Conveyor siv, thauj siv, acid thiab alkali resistant hnab looj tes rau industrial siv; Kev ua liaj ua teb siv cov kav dej thiab cov kav dej, cov hnab ammonia; Suab balloons rau kev soj ntsuam huab cua; Sealing thiab shockproof khoom rau kev sim; Lub dav hlau, tso tsheb hlau luam, phom loj thiab roj qhov ncauj qhov ntswg siv los tiv thaiv; Txawm tias cov foob pob hluav taws, lub ntiaj teb khoom siv satellites thiab lub dav hlau thiab lwm yam khoom siv txuj ci thiab thev naus laus zis tsis tuaj yeem 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 ntawm cov roj hmab ntuj. Thermoplastic Vulcanizate (Thermoplastic Vulcanizate), hu ua TPV
1, zoo elasticity thiab compression deformation kuj, ib puag ncig kuj, kev laus kuj yog sib npaug rau epDM roj hmab, nyob rau tib lub sij hawm nws cov roj kuj thiab hnyav kuj thiab dav neoprene zoo sib xws. 2, ntau yam ntawm daim ntawv thov kub (-60-150 ℃), ntau hom mos thiab tawv daim ntawv thov (25A - 54D), qhov zoo ntawm dyeing yooj yim heev txhim kho txoj kev ywj pheej ntawm cov khoom tsim. 3, kev ua haujlwm zoo heev: muaj kev txhaj tshuaj, extrusion thiab lwm yam thermoplastic txheej txheem kev ua haujlwm, ua haujlwm tau zoo, yooj yim, tsis tas yuav ntxiv cov khoom siv, muaj kuab heev, me me shrinkage tus nqi. 4, ntsuab kev tiv thaiv ib puag ncig, rov ua dua, thiab rov siv dua rau lub sijhawm yam tsis muaj kev poob qis, raws li EU kev cai ib puag ncig. 5, qhov tshwj xeeb lub ntiajteb txawj nqus yog lub teeb (0.90 - 0.97), cov tsos zoo li niaj hnub, qib nto yog siab, qhov xav tau zoo. Raws li cov yam ntxwv ua haujlwm saum toj no, TPV tau siv dav hauv ntau hom kev siv nrog cov khoom siv roj hmab ib txwm muaj. Tam sim no, qee cov khoom ntawm lub tsheb sealing sawb yog hloov los ntawm TPV ntawm thermoplastic vulcanized roj hmab nrog EPDM. TPV ntawm cov roj hmab thermoplastic vulcanized muaj qee yam zoo dua hauv kev ua tau zoo thiab kev them nqi.
