Qhov no lubricant additive yog tsim tshwj xeeb rau kev ua thiab zus tau tej cov PE thiab PP WPC (cov ntaub ntawv yas ntoo) xws li WPC decking, WPC laj kab, thiab lwm yam WPC composites, thiab lwm yam. Cov khoom tseem ceeb ntawm cov khoom no yog hloov kho copolysiloxane, uas muaj polar active. pab pawg, thiab muaj kev sib raug zoo nrog cov resin thiab ntoo hmoov. Nws tuaj yeem txhim kho qhov tawg ntawm cov hmoov ntoo thaum lub sijhawm ua thiab tsim khoom, tsis muaj kev cuam tshuam cov txiaj ntsig ntawm cov khoom siv sib xyaw ua ke hauv lub cev, thiab tuaj yeem txhim kho cov khoom siv khoom zoo. Cov khoom no muaj cov nqi siab, cov nyhuv lubrication zoo, tuaj yeem txhim kho cov matrix resin ua cov khoom, tab sis kuj tuaj yeem ua rau cov khoom smoother.

1) Txhim kho kev ua haujlwm, txo cov extruder torque, txhim kho cov khoom sib cais;
2) Cov roj nplua nyeem sab hauv & sab nraud rau WPC, txo kev siv hluav taws xob thiab ua kom muaj zog ntau lawm;
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 tswj 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 kub, ua kom lub sijhawm ntev.
Ntxiv theem ntawm 2.0 ~ 3.5% yog pom zoo. 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.
Qhov no masterbatch rau WPC kev ua haujlwm tuaj yeem thauj tau raws li 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 qhov hnyav ntawm 20kg. Cov yam ntxwv qub tseem nyob ruaj khov rau 24 lub hlis txij li hnub tsim khoom yog tias khaws cia hauv kev pom zoo cia.
