HTV high-temperature vulcanized silicone roj hmab yog ib hom khoom organosilicon uas paub txog nws cov khoom zoo xws li kub thiab kub tsis kam, UV tsis kam, hluav taws xob tiv thaiv, huab cua tsis kam, hluav taws xob rwb thaiv tsev, siab breathability, lub cev tsis muaj zog, tsis tshua muaj compression teeb, thiab qaug zog. tsis kam. Yog li ntawd, HTV high-temperature vulcanized silicone roj hmab pom dav siv nyob rau hauv aerospace, electronics, lub teeb kev lag luam, machinery, kev tsim kho, tshuaj, kev kho mob, thiab niaj hnub kev lag luam. Nyob rau hauv tsab xov xwm no, peb yuav delve rau hauv peb hom molding txheej txheem rau high-temperature vulcanized silicone roj hmab.
1. Compression Moulding:
Compression molding, tseem hu ua kub nias, yuav tsum muab cov roj hmab sib xyaw ua ntej sib xyaw nrog cov khoom siv ntxiv (xws li ob npaug tsib lossis ob zaug plaub lub silicone roj hmab vulcanizing cov neeg ua haujlwm) rau hauv pwm kub. Cov sib tov yog ces raug rau siab siv lub tshuab kub xovxwm, uas ua rau high-temperature vulcanization thiab molding.
Compression molding yog txheej txheem ntau lawm siv rau cov khoom siv silicone roj hmab. Nws suav nrog kev sib txuas cov pwm sab saud thiab qis nrog cov pwm hauv nruab nrab, yog li lub npe "compression molded silicone roj hmab." Cov txheej txheem tseem ceeb suav nrog cua sov thiab nias lub silicone roj hmab raw cov ntaub ntawv nyob rau hauv lub kaw pwm kab noj hniav los tsim cov khoom xav tau. Feem ntau, cov khoom siv raw yog sib xyaw ua ke hauv lub tshuab kneader los tsim cov khoom sib xyaw, uas tom qab ntawd hloov mus rau hauv lub tshuab vulcanization molding. Cov pwm raug kaw, siab yog thov, thiab cov roj hmab yog zoo li tus thiab kho ua ntej demolding. Cov txheej txheem no yog tsim rau cov khoom siv thermosetting.
2. Extrusion Moulding:
Extrusion molding yog zoo li nyem cov tshuaj txhuam hniav los ntawm lub raj. Lub taub hau extrusion txiav txim siab qhov cross-sectional zoo ntawm cov khoom, uas yog tsis tu ncua vulcanized thiab zoo li tus thaum nws tawm ntawm lub taub hau extrusion vim qhov kev thov ntawm kub thiab siab. Extrusion molding feem ntau tsim cov khoom lag luam nrog cov duab zoo li bar, nrog rau ntau yam kev sib tshuam xws li cov kab plaub fab lossis cov raj silicone.
Extruded silicone roj hmab cov khoom feem ntau yog tsim los ntawm cov tshuab extrusion. Cov txheej txheem nruam molding no siv cov kev sib cuam tshuam ntawm cov ntsia hlau tig hauv cov roj hmab silicone thiab cov roj hmab silicone los tsim ntau yam khoom ua tiav ntawm cov duab sib txawv. Nws yog tsim rau kev ua cov khoom siv hauv xeev silicone roj hmab nrog ob-plaub los yog platinum-raws li vulcanizing agents. Extrusion molding feem ntau yog siv los tsim cov roj hmab silicone, lub tes tsho insulating rau cov xov hlau thiab cables, thiab lwm yam khoom siv roj hmab silicone.
3. Txhaj Molding:
Kev txhaj tshuaj molding yuav tsum muaj cov cuab yeej tshwj xeeb xws li silicone roj hmab txhaj tshuab thiab feeders. Cov khoom siv raw yog ob-cov khoom ua kua sib xyaw nrog cov kua nplaum sib xws. Cov txheej txheem yog siv lub feeder kom sib tov sib xyaw thiab pub cov khoom A thiab B hauv qhov sib piv 1: 1 rau hauv lub tshuab txhaj tshuaj lub thoob. Tom qab ntawd cov khoom sib tov yog sib xyaw kom huv si siv cov khoom siv zoo li qub, txhaj rau hauv lub thoob ntim, thiab molded. Cov txheej txheem molding no ua haujlwm ntawm qhov kub qis, feem ntau nyob ib ncig ntawm 130 degrees Celsius. Txhaj tshuaj molding yog tsim rau cov yas encapsulation molding uas tsis tas yuav tsum tau kub-kub kuj, muab qhov zoo dua ntawm solid-state compression molding.
Lub tshuab ua kua roj hmab silicone yog siv dav hauv ntau yam kev lag luam, suav nrog tshuaj, khoom noj, cov txiv mis silicone, cov khoom me me, cov khoom siv dhia dej, cov khoom siv hluav taws xob, thiab cov khoom siv cable.
Cov txheej txheem saum toj no feem ntau yog siv rau molding HTV high-temperature vulcanized silicone roj hmab.
