Tus nqi qis Epoxy
Tus nqi qis Epoxy casting compound yog ib qho kev lag luam zoo tshaj plaws cov khoom siv tsim kho kom xa cov kev ua tau zoo thiab kev ntseeg siab rau siab - ntim lossis tus nqi- cov ntawv siv tau yooj yim yam tsis muaj kev cuam tshuam rau qhov tseem ceeb zoo. Cov qauv tsim tawm no yog ua raws li kev sib xyaw ua ke ntawm cov khoom siv tau yooj yim thiab muaj txiaj ntsig zoo: tus qauv bisphenol-A epoxy resin, tus nqi- siv tau zoo methyl tetrahydrophthalic anhydride hloov kho hardener system, thiab ua kom zoo quartz hmoov raws li kev ua haujlwm. Cov khoom no yog ua tiav los ntawm kev siv cov thev naus laus zis thev naus laus zis los ua kom muaj kev sib haum xeeb thiab zoo. Cov khoom lag luam tau txais txiaj ntsig zoo rau tus neeg siv -tus phooj ywg, nruab nrab- ntau yam viscosity uas sib npaug yooj yim tuav nrog kev ua haujlwm zoo rau cov dej ntws tawm, nrog rau kev nkag tau zoo heev rau kev ntub dej thiab ntim cov khoom.
Txawm hais tias nws tus nqi - qhov ua tau zoo, cov khoom siv no muab cov ntaub ntawv zoo - sib npaug ntawm cov khoom tseem ceeb rau kev siv hluav taws xob thiab kev lag luam. Nws muaj lub zog zoo txhua yam thiab tawv tawv los tiv thaiv kev ntxhov siab ntawm lub cev, txhim khu kev qha hluav taws xob rwb thaiv tsev rau kev nyab xeeb, thiab qhov tseem ceeb, cov yam ntxwv zoo tshaj plaws ntawm cov cua sov dissipation los pab tswj kev ua haujlwm kub. Lub ntsiab lus kom zoo dua ntawm Tus Nqi Tsawg Epoxy yog nws lub peev xwm los muab qhov kev cia siab rau qhov kev ua tau zoo ntawm tus nqi qis heev. Nws qhov chaw ua haujlwm tseem ceeb yog nyob rau hauv kev lag luam khoom siv hluav taws xob, qhov chaw uas nws tau siv dav rau impregnation, casting, thiab encapsulation ntawm qhuav-hom transformers, qhuav-hom reactors, ntsuas transformers (mutual inductors), thiab ntau yam tshwj xeeb transformers.
Tsis tas li ntawd, cov khoom lag luam yog qhov kev xaiv tsim nyog rau ntau yam dav dav ntawm - lub hom phiaj kev lag luam uas yuav tsum tau kho epoxy los muab kev ruaj khov, tsis muaj dej tsis zoo thiab noo noo- pov thawj barrier, thiab tiv thaiv xeb thiab corrosion, tshwj xeeb tshaj yog tom qab siab - kub curing voj voog. Rau qhov project managers thiab engineers nrhiav ib qho kev ntseeg siab, siab - cov khoom muaj nqis uas ua raws li kev txwv nyiaj txiag, Tus Nqi Qis Epoxy nthuav tawm qhov kev xaiv zoo tshaj plaws uas tsis yuam kev lag luam tawm ntawm kev lag luam thiab kev ua haujlwm tseem ceeb.

Cov Txheej Txheem Nqus Tsev Casting System
Tom qab tag nrho cov casting lub cev tau sib sau ua ke thiab cov pwm yog coated nrog tso tawm tus neeg sawv cev, tso lub cev casting rau hauv qhov cub ntawm 80-100℃thiab tuav rau 5-8 teev.
Nqa cov ntaub ntawv raws li B:A=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.
Xa lub cev qhuav qhuav rau hauv lub tank casting. Teem lub tank kub rau 70-75 degree. Ib txhij, ntxiv cov khoom preheated rau hauv lub tank casting, teem lub tank kub rau 60 degree.
Teem cov khoom kub hauv lub tank sib tov rau 60 degree. Do thiab 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 sijhawm casting mus 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 ntxiv 2 kg ntawm siab ua ntej depressurizing thiab 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.
