Pvdc (polyvinyl chloride / polyvinyl acetate copolymer) dahaarka waxaa sida caadiga ah loo isticmaalaa in isku dhafka ah ee aluminium aluminium dawooyinka dawooyinka bireed si ay u bixiyaan guryaha xannibaad ka wanaagsan iyo sifooyinka ilaalinta. Kuwa soo socda waa habka isku dhafan ee guud Pvdc daahan iyo foil aluminium dawooyinka:

Diyaari xaashida daawada: Kowaad, foornada daawadu waa la gooyaa ama la gooyaa cabbirka loo baahan yahay oo leh ballac iyo dherer ku habboon.

PVDC daboolan: Inta lagu jiro habka lamination, daahan PVDC ah ayaa lagu dabaqayaa hal dhinac oo ka mid ah foil aluminium heerka dawada ah. Dahaarka PVDC waxaa lagu dabaqi karaa habab kala duwan, kan ugu caansan kaas oo ah habka daahan daabacaadda.

a. Nadiifi dusha sare: Dusha sare ee bireed aluminium ee darajada dawooyinka ayaa loo baahan yahay in la nadiifiyo si loo hubiyo ku dhejinta dahaarka wanaagsan. Dusha sare ayaa guud ahaan lagu nadiifiyaa iyadoo la isticmaalayo nadiifiyeyaal iyo farsamooyin ku habboon.
b. Dahaarka PVDC: Xalka PVDC ama kala firdhinta ayaa loo isticmaalaa habka daahan. Xalka ama firidhsanaanta ayaa caadi ahaan ka kooban dareere, PVDC resin iyo waxyaabo kale oo lagu daro. Habka daahan ayaa laga yaabaa inuu isticmaalo rullaluistemadka, buufin ama qalab kale oo dahaarka ku habboon.
c. Qalajinta: Dahaarka ka dib, biilka aluminiumku wuxuu maraa habka qalajinta si looga saaro dareeraha ama qoyaanka dahaarka. Habka qalajinta wuxuu noqon karaa hawo kulul ama foorno si loo hubiyo in dahaarka si buuxda loo qalajiyo.

Saar: Marka dahaarka PVDC uu si buuxda u engego, ku dheji xaashida aluminiumka daawada leh walxo kale. Badanaa, lakabka kale ee alaabta baakadaha, sida filim polymer ah, waxaa lagu daboolay hal dhinac oo ka mid ah daahan PVDC si ay u bixiso shaqeyn dheeraad ah iyo ilaalin.

a. Cadaadis kulul: Inta lagu jiro habka lamination, dahaarka PVDC waxaa lagu daraa lakabka kale ee alaabta baakad by cadaadis kulul. Habkani wuxuu isticmaalaa kulayl iyo cadaadis si loo hubiyo in labada shay ay si adag isugu xidhan yihiin.
b. Xakamaynta heerkulka iyo cadaadiska: Inta lagu jiro habka cadaadiska kulul, heerkulka iyo cadaadiska ayaa loo baahan yahay in la xakameeyo si loo hubiyo in isku-dhafka u dhexeeya daahan PVDC iyo lakabka kale ee walxuhu uu yahay mid isku mid ah oo adag..

habaynta xiga: Marka dahaarka PVDC lagu daro walxo kale, Walxaha isku dhafan ayaa si dheeraad ah loo farsameyn karaa sida loo baahdo, sida jarista qaabka iyo cabbirka loo baahan yahay si loo buuxiyo shuruudaha baakadaha daawada.

Iyadoo loo marayo tillaabooyinka kor ku xusan, daahan PVDC si guul leh lagu daro karaa aluminium aluminium dawooyinka, sidaas darteed bixinta guryaha caqabada aad u fiican iyo guryaha ilaalinta baakadaha daawada.
