Izi ndi njira yopangira mafuta a WPC yopangidwa mwapadera kuti ikhale yopanga matabwa a PE ndi PP WPC (zida zapulasitiki zamatabwa). Pachimake chigawo chimodzi cha mankhwala ndi kusinthidwa polysiloxane, munali polar yogwira magulu, ngakhale kwambiri ndi utomoni ndi nkhuni ufa, m`kati processing ndi kupanga akhoza kusintha kubalalitsidwa nkhuni ufa, sikumakhudza ngakhale zotsatira za compatibilizers mu dongosolo, akhoza bwino kusintha makina katundu wa mankhwala. Zowonjezera za WPC izi ndizotsika mtengo, zokometsera zabwino kwambiri, zimatha kusintha mawonekedwe a utomoni wa matrix, komanso zimapangitsa kuti zinthuzo zikhale zosalala. Zabwino kuposa WPC wax kapena WPC stearate zowonjezera.

1. Kupititsa patsogolo kukonza, kuchepetsa torque ya extruder, kusintha kubalalitsidwa kwa filler;
2. Kuchepetsa kukangana kwamkati ndi kunja, kuchepetsa kugwiritsa ntchito mphamvu ndikuwonjezera kupanga bwino;
3. Kugwirizana kwabwino ndi ufa wa nkhuni, sikumakhudza mphamvu pakati pa mamolekyu a matabwa a pulasitiki opangidwa ndi nkhuni ndikusunga makina a gawo lapansi lokha;
4. Kuchepetsa kuchuluka kwa comptibilizer, kuchepetsa kuwonongeka kwa mankhwala, kusintha mawonekedwe a matabwa apulasitiki;
5. Palibe mpweya pambuyo pa mayeso owira, sungani kusalala kwa nthawi yayitali.
Miyezo yowonjezera pakati pa 1-5% imaperekedwa. Itha kugwiritsidwa ntchito mumayendedwe akale osungunuka osungunuka ngati Single / Twin screw extruders, jekeseni akamaumba ndi chakudya chakumbali. Kuphatikizika kwakuthupi ndi ma pellets a namwali a polima kumalimbikitsidwa.
Zowonjezera izi za WPC zitha kunyamulidwa ngati mankhwala omwe si owopsa. Ndibwino kusungidwa m'malo owuma komanso ozizira ndi kutentha kosungira pansi pa 40 ° C kuti asagwirizane. Phukusili liyenera kusindikizidwa bwino pakatha ntchito iliyonse kuti mankhwalawa asakhudzidwe ndi chinyezi.
Choyikapo chokhazikika ndi chikwama cha pepala chaluso chokhala ndi thumba lamkati la PE ndi kulemera kwa 25kg.Makhalidwe oyambilira amakhalabe osasinthika24miyezi kuchokera tsiku lopanga ngati lisungidwa mu malo ovomerezeka.
