Kev piav qhia
Epoxy yog ib qho thermosetting polymer tsim los ntawm cov tshuaj tiv thaiv ntawm epoxide "resin" nrog polyamine "hardener". Epoxy muaj ntau yam kev siv uas suav nrog cov ntaub ntawv yas fiber ntau thiab cov khoom siv dav dav. Thaum ob qho no ua ke lawv tsim ib daim ntawv cog lus ruaj ntseg. Cov txheej txheem ntawm polymerization yog hu ua "kho", thiab tuaj yeem tswj tau los ntawm qhov kub thiab txias thiab kev xaiv ntawm cov resin thiab hardener compounds; cov txheej txheem tuaj yeem siv sijhawm feeb mus rau teev. Qee cov formulations tau txais txiaj ntsig los ntawm cua sov thaum lub sijhawm kho, thaum lwm tus tsuas xav tau lub sijhawm thiab qhov kub thiab txias.
Cov ntim ntau tshaj plaws rau epoxies yog ob lub hnab ntim cov tshuab, dual cartridges, thiab cov koob txhaj tshuaj. Qhov sib xyaw ua ke ntawm 1: 1, 2: 1, 4: 1, thiab 10: 1 feem ntau yog siv nrog cov ntim no. Qee cov epoxies yog pre-mixed / khov kom nres cov txheej txheem kho thiab tom qab ntawd rhuab mus rau chav sov kom siv tau rau cov kev xav tau.
Peb Epoxy Resin Ntim Adhesives kho rau cov khoom nruj uas tsis yog ntxeem tau yooj yim ntawm kev ntxuav, thiab FDA ua raws FDA CFR 175.105 & 175.300. Cov epoxy adhesives no muaj kev tiv thaiv zoo rau dej, khoom noj khoom haus, ntxuav dej thiab cua sov. Cov neeg siv khoom xaiv peb ob lub ntsiab lus rau:
Kev ua tau zoo - High zog bonds
Kev ua tau zoo - Kev kho ceev tso cai rau lub sijhawm txaus rau kev sib dhos ntawm cov khoom loj lossis cov khoom loj. Los yog cua sov tuaj yeem siv los kho cov zaub mov qib nplaum sai dua.
Kev Ua Raws Cai - Cov epoxy nplaum no yog tsim los ntawm cov ntaub ntawv raw uas tau teev tseg hauv CFR ua zaub mov zoo.

Epoxy Resin Ntim Adhesives yog cov kua resin tsim los ntawm bisphenol-A thiab epichlorohydin. Nws raug lees paub tias yog tus qauv los ntawm ntau qhov kev hloov pauv tau tsim .Ib tug ntau yam ntawm curing agents muaj los kho cov kua epoxy resins ntawm ambient tej yam kev mob. Feem ntau siv yog aliphatic polyamines, polyamides, amidoamines,
cycloaliphatic amines thiab hloov kho versions ntawm cov curing agents.Cov tshuab no qee zaum kho tau ntawm qhov kub siab los txhim kho cov khoom xaiv xws li tshuaj tiv thaiv thiab iav hloov kub. Kev kho qhov kub thiab txias yog qhov tsim nyog thiab kev kho mob ntev ntev yuav tsum tau tsim kom muaj qhov kawg kawg yog tias siv anhydride ntawm catalytic curing agents.
Kev nyab xeeb thiab tuav
Yuav tsum tau ua thiab pom zoo cov txheej txheem kev nyiam huv hauv kev lag luam yuav tsum tau ua raws li thaum twg peb cov khoom raug ua haujlwm thiab ua tiav. Yog xav paub ntxiv thov sab laj nrog cov khoom lag luam Safety Date Sheets.
Ntim thiab Cia
Nyob rau qee qhov xwm txheej, xws li qhov kub thiab txias, peb Epoxy Resin Ntim Adhesives tuaj yeem crystallize tom qab khaws cia ntev, qhov no tuaj yeem thim rov qab los ntawm kev ua kom sov txog li 60-70 C thaum stiming. Cov khoom yuav tsum tau muab cia rau hauv qhov chaw txias thiab qhuav nyob rau hauv nws qhov qub kaw ntim, thiab tsis txhob cia raug tshav ntuj ncaj qha. Raws li cov xwm txheej no, tus kheej lub neej yuav tsum yog tsawg kawg 12 lub hlis txij li hnub tsim khoom.
