Cov txheej txheem hluav taws xob ua haujlwm, tseem hu ua PCB hluav taws xob pab pawg tiv thaiv, pleev xim rau cov xim av, pleev xim, peb cov khoom ua pov thawj los ntawm hauv qab no:
Cov txheej txheej sib xyaw tuaj yeem faib ua acrylic ester, silicone, thiab polyurethane raws li lawv cov tshuaj muaj pes tsawg leeg; Nyob rau hauv cov nqe lus ntawm cov txheej txheem caping, muaj cov kuab tshuaj kho, kho kom huv chav tsev, thiab kho kom huv.
1. Hnyav muaj acrylic resin txheej txheej (tam sim no cov khoom siv dav siv thiab cov khoom nrov hauv khw)
Nta: Nws muaj lub sijhawm qhuav, lub sijhawm kho sai, uas muaj cov khoom ua pov thawj zoo, cov xim tsawg, kev ntxhibib muaj xim, thiab yog qhov yooj yim kho.
2. Kaj Dawb Acrylic Resin Txom Nyem Txheej
Nta: UV kho, tuaj yeem qhuav lub moos hauv ob peb lub vib nas this kom dhau ntawm kaum feeb, muaj cov xim tawv, thiab ua kom zoo heev rau tshuaj corrosion thiab hnav.
3. Polyurethane Conforming Txheej
Cov yam ntxwv: Cov kev ntxhib los mos yog nkig thiab muaj cov kuab tshuaj tiv thaiv zoo heev. Ntxiv nrog rau kev ua kom zoo dua noo noo tsis kam, nws tseem muaj kev ua tau ruaj khov nyob rau hauv tsawg ib puag ncig ib puag ncig.
4. Organic silicon conformal txheej
Cov khoom muag tshiab elastic txheej tuaj yeem tso tau zoo tso, tiv thaiv kom kub siab ntawm 200 degrees, thiab yog yooj yim kho.
Ib qho ntxiv, xav txog tus nqi thiab kev ua tau zoo, tseem muaj cov txheej txheem sib txawv uas yuav tshwm sim nrog cov txheej txheem saum toj no, xws li orgetosilicon hloov cov txheej txheem conformal.
5. Fluorescent Conformal Txheej
Nta: Tom qab thov fluorescent conformal txheej, cov xim liab taws hluav taws xob illuminates zoo li, uas yog qhov tseeb thiab yooj yim los xyuas seb cov txheej txheem conforming zoo.
