Ntau zaus, ntau tus tau ntsib teeb meem ntawm kev sib khi ceev hauv zos, uas tsim nyog los tiv thaiv cov dej noo thiab hmoov av. Muaj ntau ntau yam khoom siv sealing, butyl sealant yog ib qho ntawm lawv. Kev muaj yooj yim thiab tus nqi qis, tsis zoo li lwm yam khoom, tau ua rau hom no dav.
Dab tsi yog butyl sealant
Sealants ua los ntawm cov tshuaj bituminous tau siv dav. Butyl sealants muaj hydrocarbons thiab lawv cov sulfurous, oxygen-muaj derivatives, nrog rau cov hlau thiab nitrogen-muaj cov tebchaw. Thawj txoj kev loj hlob ntawm lub sealant no tau tsim nyob rau hauv nruab nrab-60s ntawm lub xyoo pua xeem. Nyob rau hauv lub neej yav tom ntej, cov txheej txheem tsim tau raug txhim kho, ib yam li cov tshuab siv rau txhua qhov chaw thiab cov thawv ntim khoom.
Butyl sealant tom qab yuav pom nws qhov kev siv zoo tshaj plaws hauv kev tsim cov qhov rais ob chav glazed. Rau nws nws yuavtsim ib hom khoom tshwj xeeb tshwj xeeb, uas yuav hu ua butyl extruders. Nws kuj yog qee zaum siv los ua sealant rau lub teeb taub hau. Kev thov muaj zog tau thawb cov tuam txhab kom nce hom thiab ntau ntawm butyl hauv kev lag luam sealant.
Production
Kev tsim cov butyl sealants tau ntev dhau los tsis muaj qhov zais cia thiab yooj yim heev piv rau kev tsim khoom ntawm lwm hom, piv txwv li, polysulfide lossis silicone. Cov muaj pes tsawg leeg ntawm butyl suav nrog cov khoom xws li butyl rubbers thiab plasticizers, nrog rau cov khoom siv thev naus laus zis tshwj xeeb, nws yog cov khoom tom kawg uas yog cov tuam txhab tsim khoom hauv qee qhov kev faib ua feem.
Cov yas hauv cov khoom sib xyaw ntawm butyl sealant plays ib lub luag haujlwm tseem ceeb, nws yog tsim los ntawm cov roj muaj roj thiab cov khoom siv roj hmab. Lub luag haujlwm tseem ceeb tshaj plaws ntawm cov khoom siv no yog adhesion, uas yog, muaj peev xwm ntawm cov khoom sib txuas rau ib leeg ntev. Nyob rau tib lub sijhawm, plasticizers poob lawv cov khoom thiab depressurization hauv cov khoom tsim tau. Qee zaum, thaum cov neeg tsav tsheb siv lub teeb lub taub hau butyl sealant, nws tawm ntawm qhov chaw nplaum.
Hom butyl tiav nyob ntawm nws qhov kev siv. Yog hais tias butyl sealant yog siv rau lub qhov rais, nws yog tsuas yog tsim nyob rau hauv daim ntawv ntawm ib tug cylindrical tau nrog ib tug loj ntawm 7 kg, tej zaum 2.5 kg. Lub thoob no ces dipped mus rau hauv ib tug butyl extruder qhov twg nws yog siv rau ib tug txhuas thav duab nyob rau hauv kub thiab cua siab. Tom qab lub thav duab yog glued rauiav blanks rau zus tau tej cov qhov rais ob glazed.
Key Features
Butyl yog ib qho uas tsis yog-hardening, ib leeg-tiv thaiv sealant nrog zoo adhesion rau iav, txhuas thiab ntawv hlau. Qhov taw qhia tseem ceeb yog qib ntawm adhesion ntawm 93-95% rau iav, rau hlau nws qis dua me ntsis. Lub luag haujlwm tseem ceeb thiab lub luag haujlwm tseem ceeb rau butyl yog lub peev xwm los tswj kev nruj ntawm ob lub qhov rais glazed thiab rau lwm yam ntaub ntawv, tiv thaiv kev nkag mus ntawm cov dej noo thiab plua plav mus rau hauv cov khoom uas siv butyl.
Butyl sealant yog ua los ntawm cov xim dub, nws nyob ntawm cov khoom tseem ceeb. Nws yog siv cov tshuab tshwj xeeb - extruders. Nyob rau hauv extruders, butyl yog rhuab mus rau ib tug kub ntawm 110 mus rau 150 ° C, thaum nws softens thiab, nyob rau hauv lub siab, yog yooj yim siv rau ntawm qhov chaw yuav glued. Muaj cov GOST tshwj xeeb rau kev siv cov sealant no.
Daim ntawv thov
Kev siv cov khoom siv tsis muaj kev txwv. Butyl qhov rais sealant yog daim ntawv thov tseem ceeb, nws yog siv rau ntawm ntug ntawm lub thav duab thiab ua lub ntsiab sealing txheej. Cov txheej txheem butyl yog dej tsis qab thiab tiv thaiv cov pa tawm ntawm lub chamber.
Qee zaum nws yog siv los ua cov nplaum uas puas lawm. Butyl headlight sealant feem ntau yog siv los ntawm cov kws kho tsheb thiab cov neeg tsav tsheb zoo tib yam, hom no yooj yim siv thiab pheej yig. Feem ntauLub ntsiab tseem ceeb uas yuav tsum nco ntsoov thaum siv nws yog qhov ncaj qha ntawm cov hluav taws xob ultraviolet, noo noo thiab kub kub. Cov yam ntxwv no cuam tshuam rau cov khoom ntawm butyl, depressurization ntawm glued nto yog ua tau.
Yog li, tus neeg saib xyuas hermetic yog qhov tseem ceeb heev uas yuav tsum muaj ntawm tes, vim nws muaj cov khoom siv thoob ntiaj teb. Muab tso rau hauv kev xyaum yog qhov yooj yim heev.
