Qoryaha-caag isku dhafan (WPC)waa walxo isku dhafan oo ka samaysan caag ahaan sida matrix ahaan iyo alwaax ahaan buuxinta, meelaha ugu muhiimsan ee xulashada wax lagu daroWPC-yadawaa walxaha isku xidha, saliidaha, iyo midabeeyayaasha, oo leh walxo kiimiko ah iyo biocides oo aan ka fogayn.

Caadiyan,WPC-yadawaxay isticmaali kartaa saliidaha caadiga ah ee polyolefins iyo PVC, sida ethylene bis-stearamide, zinc stearate, waxes paraffin, iyo PE oxidized.

Waa maxay sababtasaliidahala isticmaalo?
Saliidahawaxaa loo isticmaalaa in wax soo saarka ee alwaax ka kooban caag ah si loo hagaajiyo processing iyo kordhinta wax soo saarka.Soo saarista alaabta isku dhafan ee balaastikada alwaaxdu waxay noqon kartaa mid gaabis ah oo tamar leh sababtoo ah dabeecadda qalalan ee alaabta.Tani waxay u horseedi kartaa habab aan waxtar lahayn, tamar lumis, iyo kororka mashiinnada.

SILIKE SILIMER 5332sheeko ahaansaliidda farsamaynta,waxay keentaa awood cusub oo lagu qanciyo WPC-yadaada.ku habboon HDPE, PP, PVC, iyo kuwa kale oo ka samaysan caag alwaax ah, oo si ballaaran loogu dabaqay guryaha, dhismaha, qurxinta, baabuurta, iyo goobaha gaadiidka.

SILIKE SILIMER 5332si toos ah ayaa loogu dari karaa walxaha isku dhafan inta lagu jiro extrusion, taas oo u oggolaanaysa in la arko faa'iidooyinka soo socda:

1) Hagaajinta farsamaynta, yaree qulqulka extruder;
2) In la yareeyo khilaafka gudaha iyo dibadda, la yareeyo isticmaalka tamarta iyo kordhinta awoodda wax soo saarka;
3) Wuxuu leeyahay iswaafajin wanaagsan oo budada alwaax ah, ma saameynayso xoogagga u dhexeeya molecules ee caagga alwaax
isku dhafan oo ilaaliya sifooyinka farsamada ee substrate laftiisa;
4) Hagaajinta guryaha hydrophobic, yaraynta nuugista biyaha;
5) Ma ubaxyo, jilicsanaan muddo dheer;
6) Dhammaystir dusha sare ah…
