Sida wax loo yaqaan 'composite',polyester-ka polyester-ka ahWaxaa si fiican loogu adeegsaday jaakadaha, fiber galaasku waxay xoojisay balaastigga, dhagaxa macmal ah, farshaxan gacmeed, iyo beero kale. Si kastaba ha noqotee, midabka huruud ah ee ressins aan fiicnayn ayaa had iyo jeer dhibaato u ahayd soosaarayaasha. Sida laga soo xigtay khubaro, sababaha caadiga ah ee huruud huruud ah ee dib-u-dhiska aan ku qanacsanayn waxaa ka mid ah waxyaabaha soo socda:

1. Intii lagu gudajiray nidaamka synthessis-ka ee resin aan ku-habboonayn, sababta oo ah huruudda gawaarida kuleylka ah ee ay keento heerkulka sare, heerkulka guud ee ethin-ka ah ee ku-meel-gaarka ah waa 180 ° ama heerkulkan ama heerkulkan ka sareeya, resin resin ayaa fududahay in loo rogo jaalaha Ku socota gabowga kuleylka, ee saameeya muuqaalka alaabada dib-u-dejinta.

2. Jiil-hubinta ay keento soo-gaadhista resin ee raajada loo yaqaan 'iltraviolet' waxaa inta badan sababa jiritaanka fardaha 'benzene' / abhydrides-ka iyo geedaha benzene iyo kuwa benzene ah oo ay soo bandhigeen styrene), taas oo laga yaabo inay u sababeeyaan oksidal-ka kuleylka xeryahooda heerkulka sare. Nacadeynta, waxay u nugul tahay kala-guurka elektiroonigga ah, sameynta resin jaalle ah.

3. Geedi socodka wax soo saarka resin, ashyaa'da ceyriinka ah ayaa la soo gaadhsiiyaa oksijiinta sababtuna tahay waxqabadka xirashada ee aaladda. Silsiladda molikalalar ee polyester-ka guud waxay ka kooban tahay oo keliya kooxaha Ester, Meradian kooxaha, iyo kooxaha ka-hortagga labanlaab, laakiin sidoo kale labanlaabmo labanlaab ah iyo dhagaxa udgoon. Waxaa lagu buufiyaa xaalufinta kuleylka kuleylka, iyo waxqabadka muuqda ee waa in midabka resin uu huruud u yahay.

4. Saamaynta waxyaabaha lagu daro sida antioxidanders, xakamaynta polymerit, dawooyinka la daaweeyo, iwm. Xaraashka pomanmerizations-ka sida caadiga ah loo isticmaalo, sida hydroquinone, waa xilgal u gariira jihooyin joogitaanka jiritaanka Quielines, taas oo ay iyagu leeyihiin midab, taas oo ay saameynayaan midabka resin. Qaar ka mid ah soosaarayaasha wakiilada joojinta ayaa wali isticmaalaya nidaamyada Amale Peroxide ee Amation-ka ee Amation-ka iyo Ketone Perikide Periokide Peraps. Resin midab leh oo midab leh.

Dabcan, waxaa jira sababo kale oo sababa resin si ay huruud isu beddelaan. Guud ahaan marka la hadlayo, kuleylka oksijiinta kuleylka ah iyo raajada ultraviolet waa sababaha ugu muhiimsan ee jaallaha jaalaha ah. Acid-ka daadanaya ee dabiiciga ah (ama aashitada aashitada) waxaa loo isticmaalaa halka loo gariiri karo aashitada udgoon ah (ama aashitada aashitada), in kasta oo loo isticmaali karo illaa xad, laakiin tixgalinta qodobbada, laakiin tixgalinta qodobo kaladuwan sida waxqabadka resin iyo Qiimaha, habkani ma aha mid wanaagsan.

Sida laga soo xigtay khubaro, marka lagu daro buuxinta gaaska inttt ee habka wax soo saarka iyo kaydinta si looga hortago in la xiro oksijiintu intii ugu badan ee suuragalka ah, oo si wax ku ool ah u nuugi kara, oo si wax ku ool ah uga horjoogsan kara hurdi-socodka dib-u-dhaca. Xallinta khabiirka ee lagu taliyay ka hortagga huruud ee loogu talagalay ressins aan ku faraxsanayn waa:

Antioxidants-ka oo aan ku jirin daadad ayaa la xushay, iyo antioxits-ka koowaad iyo antioxidayaasha waxaa loo isticmaalaa isku darka. Antioxidayaasha aasaasiga ah badanaa waa caqabad jajaban, kuwaas oo qabsan kara xag-jir bilaash ah oo xag-jir ah; Antioxits-ka auxiliary waa fosfooyin, kaas oo goonshicida hydropiropoxide, waxay sidoo kale ka saari kartaa ion-ka birta ah si looga hortago resin ka soo baxa qulqulka isirka. Haddii aad rabto inaad sii wanaajiso caabbinta jaalaha ah iyo iska caabinta cimilada, waxaa lagu talinayaa inaad kudarto UV nuugo. Ku darista UV nuugida ayaa si wax ku ool ah u xakameyn kara ifafaale huruud ah ee aaladda polymer-ka ee hoos yimaada ficillada raajooyinka ultraviolet, oo si wax ku ool ah u ilaaliyo dhimista dillaaca, jiilka dillaacyada, iyo sheekooyinku si weyn ayey u hagaajin karaan iska caabinta cimilada Alaabta, oo waxay leedahay saameyn wanaagsan oo ku habboon marka loo adeegsado antioxidant. Dabcan, isticmaalka antioxidants-ka iyo gawaarida uv-ka ma si aasaasi ah u xallin karaan dhibaatada hurdi huruud ah, laakiin waxay si wax ku ool ah uga hortagi karaan huruudda hubka ospololor ee loo yaqaan 'polyester', ku hay baska polyester-ka polyester, iyo hagaajinta tayada badeecada. darajo.

-Eenapolyester polyester-kawaxaa lagu heli karaa noocyo kala duwan oo noocyo kala duwan leh, iyo sidoo kale u-daadashada aan hubka lahayn, sida soo socota:

Waxaan sidoo kale soo saarnaaFiblass toos toos ah,Mats sariirta fiberlass, Mesh mesh, iyoFiblasglass toven.
