Sida walxo isku dhafan,Resin polyester ah oo aan dheregsanaynsi fiican ayaa loogu isticmaalay dahaarka, balaastikada lagu xoojiyay faybarka galaaska, dhagaxa macmalka ah, farsamada gacanta, iyo beeraha kale. Si kastaba ha ahaatee, midabka huruudaynta ee resinnada aan buuxin waxay had iyo jeer dhibaato ku ahayd soosaarayaasha. Sida laga soo xigtay khubarada, sababaha caadiga ah ee huruudaynta resinnada aan buuxin waxaa ka mid ah kuwan soo socda:

1. Inta lagu jiro habka isku-darka esterification ee resin-ka aan buuxin, sababtoo ah jaallaha kulaylka oo ay keento heerkul sare, heerkulka guud ee esterification ee resin-ka aan buuxin waa 180 ~ 220 ° ama ka badan, heerkulkan resin-ku si fudud ayuu u noqon karaa jaalle sababtoo ah gabowga kulaylka, taasoo saamaysa muuqaalka alaabada resin-ka.

2. Jaallaha ka dhasha soo-gaadhista resin-ka fallaaraha ultraviolet-ka waxaa inta badan sababa joogitaanka giraanta benzene ee resin-ka (oo ay ku jiraan asiidhyada dibasic/anhydrides-ka aromatic iyo giraanta benzene ee uu soo saaro styrene), taas oo laga yaabo inay sabab u tahay oksaydhaynta kulaylka ee isku-dhafka udgoonka heerkulka sare. Jajabku, wuxuu u nugul yahay kala-guurka elektaroonigga ah, taasoo ka dhigaysa resin-ka jaalle.

3. Inta lagu guda jiro soo saarista resin-ka, walxaha ceeriin ah waxaa la soo gudboonaada oksijiin sababtoo ah waxqabadka shaabadaysan ee liita ee qalabka. Silsiladda molecular-ka ee polyester-ka guud ee aan buuxin waxay ka kooban tahay oo keliya kooxaha ester-ka, kooxaha meridian-ka, iyo kooxaha antelope-ka, laakiin sidoo kale isku xidhka labanlaabka ah iyo giraanta udgoonka leh. Waxay martaa burburka oksaydhka kulaylka, waxqabadka muuqdana waa in midabka resin-ku uu noqdo jaalle.

4. Saamaynta waxyaabaha lagu daro sida antioxidants-ka, polymerization inhibitors-ka, wakiilada daaweynta, iwm. Antioxidants-ka Amine si fudud ayaa loogu beddelaa xagjirro xor ah oo nitroxid ah si ay u midabeeyaan badeecada. Inhibitors-ka polymerization-ka ee caadiga ah ee la isticmaalo, sida hydroquinone, waa Oxidation oo loo beddelo quinones marka ay joogaan quinones, kuwaas oo iyagu leh midab, sidaas darteedna saameeya midabka resin-ka. Qaar ka mid ah soosaarayaasha wakiilada daaweynta ayaa wali isticmaala nidaamyada acyl peroxide-tertiary amine iyo nidaamyada saabuunta birta ee ketone peroxide. Resin midab leh, oo si fudud loo midabayn karo.

Dabcan, waxaa jira sababo kale oo keena in resinku noqdo huruud. Guud ahaan, oksijiinta kulaylka iyo fallaaraha ultraviolet ayaa ah sababaha ugu waaweyn ee huruud noqda. Asiidhka dibasic ee buuxa (ama acid anhydride) ayaa loo isticmaalaa halkii laga isticmaali lahaa aromatic dibasic acid (ama acid anhydride), inkastoo loo isticmaali karo ilaa xad, midabka resinka waa la fududeyn karaa, laakiin marka la eego arrimo kala duwan sida waxqabadka resin iyo kharashka, habkani ma aha mid ku habboon.

Sida ay sheegeen khubaradu, marka laga soo tago buuxinta gaaska aan firfircoonayn habka wax soo saarka iyo kaydinta si looga hortago taabashada oksijiinta intii suurtogal ah, hab wax ku ool ah ayaa ah in lagu daro antioxidants iyo nuugayaasha ultraviolet, kuwaas oo si wax ku ool ah uga hortagi kara huruudaynta polyester-ka dib u dhacay. Xalalka ka hortagga huruudaynta ee khubaradu ku taliyaan ee resins-ka aan buuxin waa:

Antioxidants-ka aan ku jirin amines-ka ayaa la doortaa, antioxidants-ka aasaasiga ah iyo kuwa kaabayaasha ahna waa la isku daraa. Antioxidants-ka aasaasiga ah badanaa waa phenols-ka caqabadda ku ah, kuwaas oo qaban kara xagjirrada xorta ah ee peroxide; antioxidants-ka kaabayaasha ah waa phosphites, kuwaas oo inta ay burburinayso hydroperoxide, waxay sidoo kale ka saari kartaa ion-yada birta si looga hortago in resin-ku uu isbeddelo midab-kala-soocidda. Haddii aad rabto inaad si dheeraad ah u horumariso iska caabbinta huruudaynta iyo iska caabbinta cimilada, waxaa lagugula talinayaa inaad ku darto nuuge UV. Ku darista nuuge UV waxay si wax ku ool ah u joojin kartaa ifafaalaha huruudaynta ee walxaha polymer-ka iyadoo la adeegsanayo falgalka shucaaca ultraviolet, waxayna siin kartaa ilaalin aad u fiican badeecada, taasoo si wax ku ool ah uga hortagaysa Yaraynta dhalaalka, soo saarista dildilaaca, xumbo, iyo dilitaanka waxay si weyn u hagaajin kartaa iska caabbinta cimilada ee badeecada, waxayna leedahay saameyn isku-dhafan oo wanaagsan marka lala isticmaalo antioxidants-ka. Dabcan, isticmaalka antioxidants-ka iyo nuugayaasha UV si aasaasi ah uma xallin karaan dhibaatada huruudaynta, laakiin heer gaar ah, waxay weli si wax ku ool ah uga hortagi kartaa huruudaynta oksaydhka ee alaabada polyester-ka aan buuxin, waxay ilaalin kartaa midabka biyaha badeecada, waxayna hagaajin kartaa tayada badeecada.
