Ntau cov khoom siv ntxiv, cov roj nplua nyeem, cov stabilizers, cov neeg ua npuas dej thiab lwm yam khoom siv ntxiv yog siv rau hauv PVC foaming khoom, thiab cov additives no kuj txwv ib leeg.Hnub no, hauv kab lus no,Qingdao Sainuo yuav coj koj kom nkag siab txog cov yam ntxwv ntawm kev sib koom ua ke thiab sib npaug ntawm ntau yam khoom siv ntxiv siv hauv PVC foaming khoom.
1. Cov roj nplua nyeem sab nraud
Feem ntau siv sab nraud lubrication ntawm cov khoom foamed feem ntau suav nrog paraffin wax thiabpolyethylene wax. Paraffin wax yog ib qho yooj yim rau precipitate, yog li feem ntau siv polyethylene wax.

Lub lubrication sab nraud tsis txaus, qhov kub thiab txias hauv cheeb tsam 4 thiab 5 ntawm lub extruder yog qhov nyuaj rau kev tswj, thiab nws yog ib qho yooj yim kom dhau qhov kub thiab txias.Muaj hlwv, hlwv, yellowing thiab ntxhib phaj saum npoo ntawm phaj;Kev sib txhuam shear kub nce, ua rau cov khoom decomposition, yellowing ntawm phaj nto thiab muab tshuaj txhuam;
Cov roj lubrication ntau dhau thiab cov yas tsis zoo ua rau cov kab noj hniav tuaj yeem ua rau cov pwm kab noj hniav thiab nag lossis daus ntawm cov khoom lag luam, uas ua rau cov kab mob leucorrhea, cov phab ntsa tuab tsis sib xws thiab tsis sib xws rov qab thiab tawm ntawm qee cov tsos mob ntawm qhov chaw;
2. Internal lubricant
Cov roj nplua nyeem feem ntau suav nrog stearic acid, 60, monoglyceride, 316, thiab lwm yam.
Tsis txaus hauv lubrication, cov khoom tsis zoo dispersion, uneven plasticization, nyuaj rau tswj cov khoom thickness, tuab npuas board nyob rau hauv nruab nrab thiab nyias ntawm ob sab, leucorrhea, adhesion rau pwm kab noj hniav thiab lub zos overheating kuj tshwm sim;
Cov roj lubrication ntau dhau, cov khoom ua npuas ncauj, txo cov cua sov, thiab hloov mus rau sab nraud lubrication nyob rau hauv ib qho kub thiab yaj siab, ua rau lub lubrication tsis sib npaug;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 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;Muaj tsawg lub 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;
Ntau lub lubrication sab hauv, tsis tshua muaj lubrication sab nraud, luv luv plasticizing lub sij hawm, hnyav phab ntsa sticking, luv thermal stability lub sij hawm, thiab decomposition daj kab ntawm cov khoom nto;

3. Stabilizer
Lead ntsev stabilizer thiab calcium zinc stabilizer yog cov feem ntau siv stabilizers hauv PVC ua npuas ncauj khoom.Nrog rau ntau thiab ntau cov kev cai ntawm kev tiv thaiv ib puag ncig thiab tus nqi siab dua ntawm calcium zinc stabilizer, daim ntawv thov ntawm calcium zinc stabilizer pib ua ntau thiab dav.
Tsis txaus stabilizer, yellowing ntawm board nto, siab brittleness ntawm muab tshuaj txhuam thiab cov khoom, txo lub zog thiab tsawg foaming tus nqi;
Yog hais tias muaj ntau ntau stabilizers, tus neeg sawv cev foaming decomposes ua ntej, cov pa roj yuav dhau los ntawm qhov pub noj thiab lub tshuab nqus tsev, thiab cov qauv kab noj hniav yuav tawg cov leeg lossis cov cim;

4. Calcium hmoov
Lub teeb calcium uas muaj qhov loj me ntawm li 1200 mesh yog feem ntau haum rau cov khoom foaming.Calcium hmoov yog ib qho yooj yim nqus dej noo thiab tsim npuas thiab crazes ntawm cov khoom, uas yuav cuam tshuam rau cov tsos thiab lub cev.Yog li ntawd, xyuam xim rau kev khaws cia hauv lub caij los nag.
Thaum cov particle loj ntawm calcium carbonate loj dhau lawm, nws yog ib qho yooj yim los sib tov unevenly, lub sij hawm plasticization ntawm cov sib tov yog ncua, thiab cov ntsia hlau torque yog tsawg;
Thaum cov particle loj ntawm calcium carbonate me dhau, nws yooj yim rau agglomerate thiab hloov los ntawm cov khoom me me mus rau cov khoom loj, uas zoo ib yam li qhov tshwm sim ntawm cov khoom loj heev;

Thaum cov tshuaj calcium carbonate tsawg dhau, lub xov tooj ntawm tes tsis muaj cov tub ntxhais, cov xov tooj ntawm tes txo qis thiab cov foaming npaum li cas.
Thaum cov tshuaj calcium carbonate siab dhau lawm, cov ntsiab lus txheeb ze ntawm cov khoom siv hauv cov khoom txo qis, cov yaj lub zog txo qis, thiab cov phaj phaj yog yooj yim tawg npuas;
Yog li ntawd, ntau npaum li cas ntawm ntau yam additives muaj ib tug degree thiab kev tsis sib haum xeeb kev sib raug zoo.Ib qho me me tsis zoo, thiab tsis yog qhov loj heev.Hauv kev xyaum ua ntau lawm, peb yuav tsum mus dhau qhov kev sim rov ua dua los muab kev ua si tag nrho rau kev sib koom ua ke ntawm ntau yam khoom siv raw, nrhiav qhov zoo tshaj plaws sib npaug taw tes, ua kom zoo dua lub zog yaj thiab foaming efficiency, thiab ncua sij hawm pib.
