Xulashadagariiradda birta ah oo horay loo rinjiyeeyay(ppgi ppgl) inta badan waxaa loola jeedaa xulashada guryaha farsamada, nooca substrate (nooca daahan) iyo dhumucda daahan, waxqabadka daahan hore iyo waxqabadka daahan dambe.Isticmaalka, daxalka deegaanka, nolosha adeegga, adkeysiga, habka habaynta iyo heerka qallooca ayaa ah arrimo muhiim ah oo ay tahay in la tixgeliyo marka la dooranayogariiradda ppgiiyoppgl gariiradda.
Doorashada sifooyinka farsamada, nooca substrate iyo miisaanka daahan
Qalabka farsamada waxaa inta badan lagu doortaa iyadoo loo eegayo arrimo ay ka mid yihiin codsiga, habka farsamaynta iyo heerka qallooca.Tusaale ahaan, thexaashida saqafkaDhismuhu inta badan ma aha wax-qaadis, iyo qallafsanaantuna ma aha mid adag inta lagu jiro farsamaynta, sidaas darteedDX51Dinta badan waa la doortaa.Qaybaha qallafsanaantoodu aad u weyn tahay, agab qaabaysan sida DX52D iyo DX53D waa in la doortaa.Qaybaha leh shuruudo culus, birta qaab dhismeedka habboon waa in lagu doortaa iyadoo loo eegayo shuruudaha naqshadeynta.Hababka habaynta ee inta badan la isticmaalo ee xaashida midabaysan waxaa ka mid ah xiirid, foorarsi, duubid, iwm.
Intaa waxaa dheer, tan iyo sifooyinka farsamada ee substrate-ka waxaa badanaa loo isticmaalaa in lagu beddelo sifooyinka farsamada eesaxan midab lehwax-soo-saarka dhabta ah, iyo habka midabka midabka leh wuxuu u horseedi karaa isbeddel ku yimaada sifooyinka farsamada ee substrate, fiiro gaar ah waa in tan la bixiyaa.Nooca substrate (nooca dahaarka) iyo dhumucda dahaarka ayaa inta badan lagu doortaa arrimo ay ka mid yihiin codsiga, daxalka deegaanka, nolosha adeegga iyo adkeysiga.Ka-hortagga daxalka waa mid ka mid ah hawlaha ugu muhiimsan ee gariiradda birta midabka-dahaarka leh (ppgi ppgl gariiradda).Nooca dahaarka iyo dhumucda dahaarka ayaa ah qodobbada ugu muhiimsan ee saameeya caabbinta daxalka ee xaashida midabka midabka leh.Maadaama gariiradaha midabka leh ee dhismaha ay caadi ahaan si toos ah ugu soo baxaan jawiga jawiga, substrates sidaxaashida galvalume-ku-kululiyogo'yaal galvanized ah oo kululoo leh caabbinta daxalka wanaagsan iyo daahan qaro weyn ayaa badanaa la doortaa.
Doorashada waxqabadka daahan hore inta badan waxaa loola jeedaa doorashada nooca daahan, dhumucdiisuna waxay daahan, farqiga midabka daahan, gloss daahan, adayg daahan, dabacsanaanta daahan / adhesion, cimri dherer daahan iyo guryaha kale.
Nooca dahaarka
Dahaarka sare ee rinjigaDharka sare ee sida caadiga ah loo isticmaalo waa polyester-ka, polyester-ka silikoon wax laga beddelay, polyester-ka adkeysi badan iyo fluoride polyvinylidene, waxaana jira kala duwanaansho gaar ah oo ku saabsan adayga, dabacsanaanta/adhesion, iyo iska caabinta daxalka ee jaakadaha sare ee kala duwan.
