Cov khoom no yog cov kua roj nplua nyeem rau WPC tshwj xeeb uas tsim los rau kev tsim cov ntoo sib xyaw ntawm PE thiab PP WPC (cov ntaub ntawv yas ntoo). Cov khoom tseem ceeb ntawm cov khoom no yog hloov kho polysiloxane, muaj cov polar active pawg, zoo heev compatibility nrog resin thiab ntoo hmoov, nyob rau hauv tus txheej txheem ntawm kev ua thiab ntau lawm yuav txhim kho cov dispersion ntawm ntoo hmoov, tsis muaj kev cuam tshuam lub compatibility nyhuv ntawm compatibilizers nyob rau hauv lub system, tuaj yeem txhim kho cov khoom siv kho tshuab zoo ntawm cov khoom. Qhov no WPC additive yog tus nqi-zoo, zoo heev lubrication nyhuv, tuaj yeem txhim kho cov matrix resin ua cov khoom, tab sis kuj tuaj yeem ua rau cov khoom smoother. Zoo tshaj WPC ciab los yog WPC stearate additives.

1. Txhim kho kev ua haujlwm, txo cov extruder torque, txhim kho cov khoom siv dispersion;
2. Txo kev sib txhuam sab hauv thiab sab nraud, txo kev siv hluav taws xob thiab ua kom cov khoom ua tau zoo;
3. Kev sib raug zoo nrog cov hmoov ntoo, tsis cuam tshuam rau lub zog ntawm cov molecules ntawm cov ntoo yas sib xyaw thiab tuav cov khoom siv ntawm lub substrate nws tus kheej;
4. Txo tus nqi ntawm compatibilizer, txo cov khoom tsis xws luag, txhim kho cov tsos ntawm cov khoom yas ntoo;
5. Tsis muaj nag lossis daus tom qab kev sim boiling, ua kom du du.
Cov qib ntxiv ntawm 1 ~ 5% yog qhia. Nws tuaj yeem siv rau hauv cov txheej txheem melting classical zoo li Ib leeg / Twin ntsia hlau extruders, txhaj tshuaj molding thiab sab pub. Lub cev sib xyaw nrog nkauj xwb polymer pellets raug pom zoo.
WPC cov khoom siv ntxiv no tuaj yeem raug thauj los ua cov tshuaj tsis muaj phom sij. Nws raug nquahu kom muab khaws cia rau hauv qhov chaw qhuav thiab txias nrog qhov ntsuas kub qis dua 40 ° C kom tsis txhob muaj agglomeration. Lub pob yuav tsum tau muab kaw kom zoo tom qab siv txhua yam los tiv thaiv cov khoom los ntawm kev cuam tshuam los ntawm kev ya raws.
Cov txheej txheem ntim khoom yog lub hnab ntim khoom siv tes ua nrog PE puab lub hnab nrog net hnyav ntawm 25kg.Cov yam ntxwv qub tseem nyob ruaj khov rau24lub hlis txij li hnub tsim khoom yog tias khaws cia hauv kev pom zoo cia.
