Tsawg viscosity Casting Resin
Tsawg Viscosity Casting Resin yog ntau yam, tsim ua kua polymer txheej txheem tsim feem ntau rau potting, encapsulation, thiab casting daim ntaub ntawv uas intricate nthuav dav capture thiab void- pub dawb yog qhov tseem ceeb. Feem ntau raws li epoxy chemistry, cov resin no yog cov khoom tsim los ntawm kev tshawb fawb uas suav nrog cov tshuaj reactive diluents thiab siv cov txheej txheem polymerization siab heev kom kho nws cov viscosity kom qis, yooj yim pourable xeev. Thaum raug tshav kub nyob rau hauv lub xub ntiag ntawm ib tug matched curing tus neeg sawv cev, cov khoom tau dhau ib tug tswj tus ntoo khaub lig- txuas cov tshuaj tiv thaiv. Cov txheej txheem no hloov nws los ntawm cov kua hauv lub xov tooj mus rau hauv ib qho khoom, peb - cov khoom siv hluav taws xob sib txuas ua ke, ua rau cov khoom kho nrog lub zog, hardness, thiab cov khoom ua haujlwm zoo.
Daim ntawv thov spectrum rau Low Viscosity Casting Resin yog qhov dav dav. Hauv kev lag luam hluav taws xob thiab hluav taws xob, nws yog ib qho tseem ceeb rau potting transformers, ntsuas transformers, motors, capacitors, thiab rau insulating thiab tiv thaiv rhiab hluav taws xob Cheebtsam thiab luam Circuit Court boards (PCBs). Nws zoo seals tawm cov dej noo, plua plav, thiab cov kab mob, tiv thaiv luv luv Circuit Court thiab ua rau cov cuab yeej siv tau ntev thiab kev cia siab ntawm thaj chaw. Hauv kev tsim cov khoom sib xyaw ua ke, cov khoom lag luam ua raws li cov ntaub ntawv matrix rau cov khoom siv fiber ntau thiab cov khoom siv hauv cov ntxhia, ua rau cov khoom siv siab - lub zog, qhov hnyav ntawm lub tshuab nqus tsev casting lossis resin hloov molding (RTM). Nws qhov tseeb thiab kev ruaj ntseg kuj ua rau nws nrov hauv kev lag luam kho kom zoo nkauj thiab khoom siv tes ua los tsim cov khoom siv lead ua- ntshiab embedments, hniav nyiaj hniav kub, thiab imitation stoneware. Hauv kev tsim kho thiab kev tsim vaj tsev, nws yog siv rau kev txhaj tshuaj tiv thaiv kab mob, anchoring, thiab hauv pem teb txheej. Txawm tias cov chaw tshwj xeeb xws li kev tsim khoom siv kho mob siv qee qib ntawm Low Viscosity Casting Resin rau encapsulating rhiab Cheebtsam. Qhov kev siv dav dav no qhia txog nws lub luag haujlwm raws li cov khoom siv tseem ceeb hauv kev lag luam niaj hnub no.

Standard Vacuum Casting System Txheej txheem
Tom qab sib sau ua ke lub cev casting thiab thov tso tawm tus neeg sawv cev rau pwm, muab tso rau hauv qhov cub ntawm 80-100℃rau 5-8 teev.
Nqa cov ntaub ntawv raws li A:B=1:1 thiab muab tso rau hauv qhov cub kub. 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. Teem lub tank kub rau 70-75 degree. Tib lub sijhawm, ntxiv cov khoom siv A thiab B preheated rau lub tank casting, tom qab ntawd ntxiv cov fillers raws li tus qauv piv. Teem lub tank kub rau 60 degree.
Teem lub tank sib tov rau 60℃thiab do rau 90 feeb thaum stirring. Tshem tawm lub tank 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, lub sij hawm casting yuav tsum tau tswj ntawm 30-70 feeb. Tom qab nchuav, tuav 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 ntawm lub thawv.

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 tias cov khoom tuaj rau hauv kev sib cuag nrog lub qhov muag, tam sim ntawd yaug nrog dej huv, 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 tias cov khoom nkag mus rau ntawm daim tawv nqaij, so nws nrog ib daim ntaub mos, huv si los yog ntaub so ntswg, ces ntxuav tes nrog xab npum.
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.
