1. Cov yam ntxwv ntawm qhov tsis raug ntxiv ntawm cov roj nplua nyeem nyob rau hauv PVC ua npuas ncauj khoom
Paraffin wax thiabPE wax yog cov feem ntau siv sab nraud slip agents hauv cov khoom foaming.Paraffin wax yog ib qho yooj yim rau precipitate, yog li PE siv quav ciab feem ntau yog siv.

Lub lubrication sab nraud yog tsis txaus, qhov kub thiab txias nyob rau hauv cheeb tsam 4 thiab 5 ntawm lub extruder yog tsis yooj yim los tswj, thiab nws yog ib qho yooj yim mus dhau qhov kub thiab txias.Muaj hlwv, hlwv, yellowing thiab ntxhib phaj saum npoo ntawm phaj;Qhov nce ntawm kev sib txhuam shear kub ua rau cov khoom decomposition, yellowing thiab muab tshuaj txhuam rau ntawm lub phaj saum npoo, ntau dhau ntawm cov zawv zawg sab nraud thiab cov yas tsis zoo, ua rau scaling nyob rau hauv lub puab kab noj hniav ntawm cov pwm thiab nag lossis daus rau ntawm qhov chaw ntawm cov khoom, uas yog feem ntau ua rau cov phab ntsa tsis sib xws. thickness thiab irregular back and forth txav ntawm qee cov tsos mob ntawm qhov chaw.
2. Cov yam ntxwv ntawm kev sib ntxiv ntawm cov roj nplua nyeem hauv PVC ua npuas ncauj
(1) Lub lubrication tsis txaus, dispersion tsis zoo ntawm cov ntaub ntawv, tsis sib xws plasticization, nyuaj rau tswj cov thickness ntawm cov khoom, tuab nyob rau hauv nruab nrab thiab nyias ntawm ob sab ntawm lub rooj tsavxwm ua npuas ncauj, adhesion rau pwm kab noj hniav thiab lub zos overheating;Cov roj lubrication ntau dhau ua rau cov khoom foamed nkig thiab cov cua kub tsis kam txo;Nyob rau hauv qhov kev txiav txim ntawm tej yam kub thiab melting siab, nws yog hloov mus rau lwm lubrication, uas ua rau lubrication imbalance.

(2) Tsis txaus lubrication sab hauv thiab sab nraud, siab yaj viscosity, siab plasticizing torque, loj yaj phab ntsa adhesion, daj decomposition kab ntawm cov khoom nto, tsis zoo deg smoothness thiab txo cov khoom ntawm cov khoom;Lub lubrication sab hauv thiab sab nraud yog ntau dhau, lub plasticizing torque me me, thiab cov yaj plasticization yog pom tseeb tsis txaus.Txawm hais tias cov khoom muaj smoothness zoo, lub siab taw tes adhesion tsis zoo, uas cuam tshuam rau cov khoom siv kho tshuab ntawm cov khoom.
(3) Tsis muaj lubrication sab hauv thiab ntau ntxiv lubrication, lub sij hawm plasticizing yog obviously ntev, lub plasticizing torque yog txo, cov khoom yog nyuaj rau tsim thiab ua nkig;Muaj ntau lub lubrication sab hauv thiab tsis tshua muaj lubrication sab nraud, lub sij hawm plasticizing yog shortened, muaj ib tug loj phab ntsa sticking tshwm sim, lub thermal stability lub sij hawm luv luv, thiab muaj decomposition daj kab ntawm cov khoom nto.

High ceevoxidized polyethylene ciab yog cov roj nplua nyeem ua haujlwm siab nyob rau hauv thiab sab nraud, muab cov txiaj ntsig zoo ntawm plasticizing thiab demoulding.

3. Lub lubrication sab hauv thiab sab nraud yog tsis txaus, lub yaj viscosity yog loj, lub plasticizing torque yog loj, lub melt phab ntsa sticking tshwm sim yog loj, cov khoom nto muaj ib tug daj ciam, lub nto smoothness yog tsis zoo, thiab txhua yam khoom ntawm lub cov khoom qis;
Lub lubrication sab hauv thiab sab nraud yog ntau dhau, lub plasticizing torque yog me me, thiab cov yaj plasticization yog pom tseeb tsis txaus.Txawm hais tias cov khoom muaj smoothness zoo, lub siab taw tes adhesion tsis zoo, uas cuam tshuam rau cov khoom siv kho tshuab ntawm cov khoom;
Nrog tsawg lub hauv lubrication thiab ntau ntxiv lubrication, lub sij hawm plasticizing yog obviously ntev, lub plasticizing torque yog txo, thiab cov khoom yog nyuaj rau tsim thiab nkig;
Ntau lub lubrication sab hauv, tsis tshua muaj lubrication sab nraud, lub sij hawm plasticizing luv luv, cov phab ntsa loj dua, lub sij hawm thermal stability luv dua, thiab decomposition daj kab ntawm cov khoom nto.
Qingdao Sainuo Chemical Co., Ltd.Peb yog cov chaw tsim khoom rau PE ciab, PP ciab, OPE ciab, EVA ciab, PEMA, EBS, Zinc / Calcium Stearate ....Peb cov khoom tau dhau REACH, ROHS, PAHS, FDA kuaj.
