Kala-firdhiyeyaasha iyo saliidaha labaduba waa kuwo caadi ahaan loo isticmaalo waxyaabaha lagu daro midabka balaastiga ah.Haddii waxyaabahan lagu daro alaabta ceeriin ee alaabta, waxay u baahan yihiin in lagu daro alaabta ceeriin ee resin si isku mid ah oo ku jirta caddaynta u dhiganta midabka, si looga fogaado kala duwanaanshaha midabka ee wax soo saarka xiga.
Noocyada kala firdhiya waa: polyureas fatty acid, stearate base, polyurethane, saabuunta oligomeric, iwmSaliiduhu waxay leeyihiin sifooyin kala firdhisan oo wanaagsan, waxayna sidoo kale wanaajin karaan dareeraha iyo sifooyinka sii daynta caaryada ee balaastikada inta lagu jiro qaabeynta.
Saliidaha waxaa loo qaybiyaa saliidaha gudaha iyo saliidaha dibadda.Saliidaha guduhu waxay leeyihiin iswaafajin gaar ah oo ay la socdaan resins, kaas oo yarayn kara isku xidhnaanta silsiladaha unugyadu, yaraynta dhalaalka, oo wanaajiso dareeraha.Iswaafajinta udhaxeysa saliidaha dibadda iyo xabagta, waxay ku dheggan tahay dusha sare ee xabagta dhalaalaysa si ay u sameeyaan lakab kelli ah oo saliid leh, taas oo yaraynaysa khilaafka u dhexeeya resin iyo qalabka wax lagu sameeyo.Saliidaha waxaa inta badan loo qaybiyaa qaybaha soo socda iyadoo loo eegayo qaab dhismeedka kiimikada:
(1) Nooca gubanaya sida paraffin, polyetylen, wax polypropylene, wax yar yar, iwm.
(2) Asiidhada dufanka leh sida stearic acid iyo stearic acid.
3 .
(4) Saabuunta birta sida stearic acid, zinc stearate, calcium stearate, pot stearate, magnesium stearate, stearate rasaasta, iwm. waxay leeyihiin labadaba xasilinta kulaylka iyo saamaynta saliidaynta.
(5) Saliidaha door ka ciyaara sii daynta caaryada, sida polydimethylsiloxane (saliid silicone methyl), polymethylphenylsiloxane (saliid phenylmethyl silicone oil), polydiethylsiloxane (saliid silikoon ethyl) iwm.
Nidaamka qaabaynta duritaanka, marka midabaynta qalalan la isticmaalo, wakiilada daaweynta dusha sare sida saliidda macdanta cad iyo saliidda faafinta ayaa guud ahaan lagu daraa inta lagu jiro isku dhafka si ay u ciyaaraan doorka adsorption, sifeynta, faafinta iyo sii deynta caaryada.Marka midabaynta, alaabta ceeriin sidoo kale waa in lagu daraa qaybinta dhexdhexaadka ah ee saamiga.Marka hore ku dar wakiilka daaweynta dusha oo si siman u faafi, ka dibna ku dar toner oo si siman u faafi.
Marka la dooranayo, iska caabinta heerkulka firidhiyaha waa in lagu go'aamiyaa iyadoo loo eegayo heerkulka qaabaynta alaabta ceeriin ee caagga ah.Marka laga eego dhinaca qiimaha, mabda'a ahaan, kala-baxa loo isticmaali karo heerkulka dhexdhexaadka ah iyo kuwa hooseeya waa in aan loo dooran caabbinta heerkulka sare.Heerkulka sare ee kala firdhiyaa wuxuu u baahan yahay inuu adkaysto ka sarreeya 250 ℃.
