Tsawg Thermal Expansion Epoxy
Tsawg Thermal Expansion Epoxy yog qhov tseeb -cov khoom siv ua haujlwm tau tsim los daws cov teeb meem tseem ceeb ntawm qhov tsis txaus ntseeg hauv cov ntawv thov uas muaj qhov kub thiab txias hloov pauv. Qhov tshwj xeeb epoxy formulation no ua tiav qhov txo qis Coefficient ntawm Thermal Expansion (CTE) los ntawm cov qauv tsim qauv tsim qauv tsim los yog cov tswv yim hloov kho siab heev. Nws yog tsim los ntawm lub hauv paus ntawm siab -zoo bisphenol-A epoxy resin, methyl tetrahydrophthalic anhydride hloov kho hardener, thiab ua tib zoo graded quartz hmoov, tag nrho cov txheej txheem raws li kev tswj xyuas kom zoo ib yam. Cov khoom tshwm sim nthuav tawm qhov hloov pauv me me thaum raug tshav kub lossis txias, cov cuab yeej tseem ceeb rau kev tswj kev ua siab ntev thiab tiv thaiv kev ntxhov siab hauv kev sib koom ua ke lossis cov khoom sib dhos.
Lub peev xwm ntawm Tsawg Thermal Expansion Epoxy los tswj nws cov duab thiab qhov loj ntawm qhov dav ntawm qhov kub thiab txias ua rau nws yog ib qho khoom siv tseem ceeb hauv ntau qhov siab -tech fields. Hauv kev ntim khoom hluav taws xob thiab kev lag luam semiconductor, nws yog siv rau underfilling, glob topping, thiab encapsulating ilv chips thiab substrates, tiv thaiv kev sib koom ua ke tsis ua hauj lwm los ntawm CTE mismatch. Nyob rau hauv lub cheeb tsam ntawm precision instruments thiab optical systems, cov khoom yog ib qho tseem ceeb rau kev sib txuas lo ntsiab muag, tsom iav, thiab sensors qhov twg txawm micron - theem txav tuaj yeem cuam tshuam qhov tseeb. Lub aerospace thiab lub zog tshiab tau tso siab rau cov khoom siv no rau cov khoom siv uas yuav tsum ua kom muaj kev kub ntxhov hnyav yam tsis muaj kev cuam tshuam txog kev ncaj ncees. Tsis tas li ntawd, nyob rau hauv siab - qhov kub thiab txias kev lag luam thiab kev siv engineering tshwj xeeb, Tsawg Thermal Expansion Epoxy muab kev ua tau zoo uas qhov kev ntxhov siab thermal yuav ua rau cov khoom siv tsis zoo. Rau cov kws tsim qauv tsim cov tshuab uas qhov ntsuas qhov tseeb tsis yog- sib tham tau, kev qhia cov khoom lag luam yog ib kauj ruam tseem ceeb los ua kom ntseeg tau ntev - lub sijhawm kev ntseeg siab thiab kev ua haujlwm.

Cov Txheej Txheem Nqus Tsev Casting System
Tom qab tag nrho cov casting lub cev yog sib sau ua ke thiab molded nrog tso tawm neeg sawv cev, muab tso rau hauv ib lub qhov cub ntawm 80-100℃rau 5-8 teev.
Siv cov khoom raws li B: A piv ntawm 1: 1 thiab muab tso rau hauv qhov cub kub tsis tu ncua. Preheat qhov cub kom 70℃ntawm chav tsev kub (25 degree) thiab tuav rau 2-3 teev.
Hloov lub cev qhuav qhuav mus rau lub tank casting nrog lub tank kub teem rau 70-75 degree. Ib txhij, ntxiv cov khoom preheated rau lub tank casting, teem lub tank kub rau 60 degree.
Teem cov khoom kub hauv lub tank sib tov rau 60 degree. Thaum stirring, ib txhij tshem tawm lub tshuab nqus tsev mus rau 50-150Pa. Saib xyuas los ntawm cov iav pom tias cov khoom tau degassed ua ntej casting.
Nyob ntawm qhov loj ntawm lub cev casting, tswj lub sij hawm casting rau 30-70 feeb. Tom qab casting, tswj lub tshuab nqus tsev rau 30-40 feeb, tom qab ntawd tawg lub tshuab nqus tsev thiab siv 2 kg ntawm siab ua ntej tshem tawm lub cev casting ntawm lub tank.

Cov kev ceev faj
1. Hnav hnab looj tes thiab daim npog qhov ncauj thaum tuav kom tsis txhob muaj kev sib cuag ntawm daim tawv nqaij ncaj qha nrog cov khoom.
2. Yog hais tias cov khoom ntawd los rau hauv lub qhov muag, tam sim ntawd yaug nrog huv si, khiav dej rau 10 mus rau 15 feeb. Yog tias tsis xis nyob heev, mus nrhiav kev kho mob tam sim ntawd tom qab yaug.
3. Yog hais tias cov khoom nkag mus rau ntawm daim tawv nqaij, so nws nrog ib tug mos, huv si daim ntaub so ntswg los yog ntaub, ces ntxuav nrog cov tshuaj ntxuav tes.
4. Yog tias cov khoom nqus tau vapors thiab ua rau tsis xis nyob, tam sim ntawd txav mus rau sab nraud. Thaum mob hnyav, nrhiav kev kho mob.
