Ib qho epoxy curing tus neeg sawv cev yog cov tshuaj siv los khoepoxy coblos ntawm reacting chemically nrog cov epoxy pawg nyob rau hauv epoxy resin los tsim ib tug ntoo khaub lig-txuas qauv, yog li ua rau cov epoxy resin ib tug tawv, ruaj khov khoom.
Lub luag haujlwm tseem ceeb ntawm epoxy curing agents yog los txhim kho lub hardness, abrasion tsis kam, thiab tshuaj tiv thaiv ntawm epoxy resins, ua rau lawv cov khoom siv ntev thiab ruaj khov, uas yog ib feem tseem ceeb ntawm epoxy pultruded composites. Tsab ntawv xov xwm no qhia txog yuav ua li cas xaiv tus epoxy-kho tus neeg sawv cev raws li qhov sib txawv:
Raws li kev kho mob
- Kho ntawm chav tsev kub: Yog tias yuav tsum tau kho ceev ceev ntawm chav tsev kub, aliphatic amine curing agents xws li ethylenediamine thiab diethylenetriamine tuaj yeem xaiv; Yog tias qhov curing ceev tsis tas yuav tsum siab, thiab tsom rau lub sijhawm ua haujlwm, cov neeg ua haujlwm kho polyamide tuaj yeem xaiv.
- Thaum tshav kub kub kho: Rau kev kub siab ua haujlwm thiab cov khoom siv kho tshuab, cov tshuaj tsw qab amine curing, xws li diaminodiphenylsulfone (DDS), thiab lwm yam., tuaj yeem siv tau; rau qhov kub thiab txias ceev curing, hloov kho amine curing agents nrog accelerators tuaj yeem txiav txim siab.
- Kho nyob rau hauv tshwj xeeb tej yam kev mob: rau kho nyob rau hauv ib tug ntub ib puag ncig, ib tug ntub curing curing tus neeg sawv cev yuav raug xaiv; rau lub teeb curing system, tus neeg sawv cev kho nrog photoinitiator thiab epoxy acrylate tuaj yeem xaiv.
Raws li cov kev xav tau ntawm kev ua haujlwm
- Cov khoom siv kho tshuab: yog tias yuav tsum muaj qhov tawv tawv thiab siab zog, cov tshuaj anhydride curing tuaj yeem xaiv tau; Yog tias xav tau kev ua tau zoo thiab kev cuam tshuam, cov khoom siv tawv tawv xws li cov roj hmab polysulfide yog qhov tsim nyog.
- Tshuaj tiv thaiv: siab yuav tsum tau nyob rau hauv acid, alkali, thiab hnyav kuj,phenolic cobcuring tus neeg saib xyuas lossis qee qhov hloov kho amine curing tus neeg saib xyuas yog qhov tsim nyog.
- Thaum tshav kub kub tsis kam: Rau qhov kub-kub ib puag ncig, xws li saum toj 200 ℃, silicone curing agent lossis curing agent nrog cov qauv polyaromatic tuaj yeem txiav txim siab.
Raws li kev siv ib puag ncig
- Sab hauv ib puag ncig: kev tiv thaiv ib puag ncig siab, dej-raws li epoxy curing tus neeg saib xyuas lossis tsis tshua muaj hluav taws xob aliphatic amine curing tus neeg saib xyuas yog qhov tsim nyog.
- Sab nraum zoov ib puag ncig: yuav tsum muaj huab cua zoo tiv thaiv, alicyclic amine curing agents nrog UV tiv taus zoo dua.
- Ib puag ncig tshwj xeeb: Hauv ib puag ncig uas xav tau kev nyiam huv siab xws li zaub mov thiab tshuaj, cov tshuaj tsis muaj tshuaj lom lossis tsis muaj tshuaj lom epoxy curing agents xws li zaub mov-kev nyab xeeb ntawv pov thawj polyamide curing agents yuav tsum tau xaiv.
Xav txog cov txheej txheem yuav tsum tau ua
- Lub sijhawm ua haujlwm: Rau lub sijhawm ua haujlwm ntev, xaiv tus neeg saib xyuas latent curing, xws li dicyandiamide, thiab lwm yam. Rau kev ua haujlwm luv luv thiab lub sijhawm kho, xaiv cov tshuaj tua kab mob aliphatic amine curing sai.
- Curing Appearance: Rau qhov tsis muaj xim thiab pob tshab curing zoo li, xaiv alicyclic amine curing agents, thiab lwm yam. Rau cov xim uas tsis muaj xim, xaiv cov tshuaj amine curing uas qis dua.
Ua ke nrog tus nqi tsim nyog
- Raws li qhov ua tau raws li qhov yuav tsum tau ua, sib piv cov nqi thiab ntau npaum li cas ntawm cov tshuaj tua kab sib txawv. Tus nqi ntawm cov tshuaj tua kab mob amine feem ntau yog qis, thaum qee qhov kev ua haujlwm tshwj xeeb kho cov neeg ua haujlwm xws li fluorine-muaj thiab silicone-muaj cov tshuaj tua kab mob yog kim dua.
