Phenolic resinyog cov khoom siv polymer tsim los ntawm kev sib xyaw ntawm phenols (xws li phenol) thiab aldehydes (xws li formaldehyde) nyob rau hauv acid lossis base catalysis. Nws muaj kev tiv thaiv cua sov zoo heev, rwb thaiv tsev thiab lub zog kho tshuab thiab siv rau hauv hluav taws xob, tsheb, aerospace thiab lwm yam teb.
Phenolic resin (Phenolic Resin) yog cov khoom siv hluavtaws uas tau tsim los ntawm kev lag luam. Nws yog ua los ntawm kev sib xyaw ua ke ntawm phenol lossis nws cov derivatives (xws li cresol, xylenol) thiab formaldehyde. Raws li hom catalyst (acidic lossis alkaline) thiab qhov sib piv ntawm cov khoom siv raw, nws tuaj yeem muab faib ua ob pawg: thermoplastic thiab thermosetting.
Cov yam ntxwv tseem ceeb Cov khoom siv lub cev:
1. Feem ntau nws yog ib yam khoom tsis muaj xim los yog xim av daj uas pom tseeb. Cov khoom muag hauv khw feem ntau ntxiv cov xim kom muaj ntau yam xim.
2. Nws muaj kev tiv taus kub zoo heev thiab siv tau ntev ntawm 180 ℃. Nws tsim cov pa roj carbon seem ntau (kwv yees li 50%) ntawm qhov kub siab.
3. Cov yam ntxwv ua haujlwm:
Kev rwb thaiv hluav taws xob zoo heev, tiv taus hluav taws (tsis tas yuav ntxiv cov tshuaj tiv thaiv hluav taws) thiab ruaj khov.
Nws muaj lub zog kho tshuab siab, tab sis nws yooj yim thiab yooj yim nqus dej noo.
4. Kev faib tawm thiab cov qauv Thermoplastic phenolic resin: Cov qauv linear, xav tau ntxiv cov neeg sawv cev kho (xws li hexamethylenetetramine) los txuas thiab kho.
5. Kev ntsuas kubPhenol-formaldehyde resin: Cov qauv sib txuas ntawm lub network, tuaj yeem kho tau los ntawm cua sov, muaj kev tiv taus cua sov thiab lub zog kho tshuab siab dua
Phenolic resin feem ntau yog siv los tsim ntau yam yas, tshuaj pleev xim, nplaum thiab cov xov hluavtaws.
