Phenolic Resin:Phenolic resin ndi chinthu cha matrix chomwe chimagwiritsidwa ntchito popanga zinthu.mankhwala opangira ma phenolic opangidwa ndi ulusi wagalasiyokhala ndi kukana kutentha bwino, kukana mankhwala komanso mphamvu zamagetsi zotetezera kutentha. Utomoni wa phenolic umapanga kapangidwe ka netiweki ya miyeso itatu kudzera mu polycondensation reaction, zomwe zimapangitsa kuti zinthuzo zikhale zolimba komanso zokhazikika.

Ulusi wa Galasi:Ulusi wagalasi ndiye chinthu chachikulu cholimbitsa mphamvu cha ulusi wagalasi wolimbitsa phenolic, chokhala ndi mphamvu zambiri, modulus yambiri komanso kukana kutentha bwino. Kuwonjezera ulusi wagalasi kumawongolera kwambiri mawonekedwe a makina a chinthucho, zomwe zimathandiza kuti chikhalebe cholimba komanso cholimba kwambiri kutentha kwambiri komanso m'malo ovuta.

Zodzaza ndi zowonjezera: Pofuna kupititsa patsogolo magwiridwe antchito a zinthuzo,mankhwala opangira ma phenolic opangidwa ndi ulusi wagalasinthawi zambiri amawonjezeredwanso zinthu zina zodzaza ndi zowonjezera, monga zodzaza mchere, zoletsa moto, mafuta odzola, ndi zina zotero. Zodzaza ndi zowonjezerazi zimatha kupititsa patsogolo kukana kwa kusweka, choletsa moto komanso magwiridwe antchito a zinthuzo.

Chiŵerengero cha Monomer

Mu zinthu zopangidwa ndi ulusi wagalasi, chiŵerengero cha phenolic resin ndi ulusi wagalasi nthawi zambiri chimakhala 1:1. Chiŵerengerochi chimapangidwa mosamala kuti zinthuzo zigwire bwino ntchito. Pakadali pano, zodzaza nthawi zambiri zimakhala pakati pa 20% ndi 30% kuti zichepetse mtengo wa zinthuzo ndikuwonjezera kuthekera kozikonza. Koma zowonjezera nthawi zambiri zimakhala pakati pa 5% ndi 10% ndipo zimagwiritsidwa ntchito kupititsa patsogolo mawonekedwe a zinthuzo ndi kuthekera kozikonza. Chiŵerengerochi chimasinthidwa malinga ndi zofunikira zinazake zogwiritsira ntchito komanso ukadaulo wokonza kuti zitsimikizire kuti zinthuzo zitha kugwira ntchito bwino m'malo osiyanasiyana.

Madera Ogwiritsira Ntchito

Chifukwa cha mphamvu zake zabwino zotetezera kutentha, mphamvu ya makina komanso kukana dzimbiri,galasi la ulusi wa phenolic wopangira zinthuimagwiritsidwa ntchito kwambiri pa zamagetsi, makina, makampani opanga mankhwala, magalimoto ndi zina. Makamaka pakufunika kupirira katundu wolemera, kukana kugundana ndi kutentha kwambiri, izi zikuwonetsa ubwino wake wapadera. Nthawi yomweyo, magwiridwe ake abwino opangira zinthu amathandizanso kuti athe kukwaniritsa zosowa zamitundu yosiyanasiyana, zomwe zimapangitsa kuti mafakitale azipanga mosavuta.
