PVC foaming khoom xav tau kev sib ntxiv ntawm ntau yam additives. Niaj hnub no, cia Qingdao Sainuo siv quav ciab chaw tsim tshuaj paus coj koj kom nkag siab qhov tsis sib xws ntawm ntau yam additives!

1. Stabilizer
Lead ntsev stabilizer thiab calcium zinc stabilizer yog cov khoom siv stabilizers feem ntau siv hauv PVC ua npuas dej. 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 roj yuav dhau los ntawm lub qhov noj thiab lub tshuab nqus tsev, thiab cov qauv kab noj hniav yuav tawg cov leeg lossis cov cim;
2. External lubricant
Feem ntau siv sab nraud lubrication ntawm cov khoom foamed feem ntau suav nrog paraffin wax thiabPE ciab . Paraffin wax yog ib qho yooj yim rau precipitate, yog li PE siv quav ciab feem ntau yog siv.

Cov zawv zawg 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;
Ntau dhau los ntawm sab nraud thiab tsis zoo plasticization ua rau scaling nyob rau hauv cov pwm kab noj hniav thiab nag lossis daus ntawm cov khoom nto, uas yog prone rau leucorrhea, tsis sib npaug phab ntsa thickness thiab irregular back and forth txav ntawm ib co tsos mob ntawm qhov chaw;
3. Internal lubricant
Internal lubrication tsis txaus, 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 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, 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;
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 los 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 qhov me me ntawm calcium carbonate loj dhau lawm, nws yooj yim rau kev sib xyaw tsis sib xws, lub sij hawm plasticization ntawm kev sib xyaw yog qeeb, thiab cov ntsia hlau torque 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 tus nqi txo;
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;

5. Foaming regulator
Foaming regulator feem ntau yog hais txog acrylate processing additives nrog viscosity saum toj no 10. Ntoo yas foaming khoom xws li ecological ntoo thiab phab ntsa tiv thaiv board feem ntau siv hom nrog ceev plasticization. Foaming regulator nrog qeeb plasticization thiab siab yaj lub zog feem ntau yog siv rau foaming board, tshwj xeeb tshaj yog lub rooj tsavxwm.
Lub tshuab ua npuas dej tsis txaus, lub zog yaj lub zog tsis zoo, lub xov tooj ntawm tes tsis sib xws, lub xov tooj ntawm tes yuav tshwm sim hauv ntu thiab qhov ceev yuav nce;
Muaj ntau ntau cov foaming regulators, lub qhuav lub zog yog ib yam nkaus thiab loj, lub npuas nyob rau hauv lub qhuav yuav tsis nthuav, cov khoom density yog high school, thiab lub phaj nto yog nws laim ntoom kab, distortion thiab deformation;
6. Foaming agent
Qhov ntau tshaj ntawm foaming agent yog AC yellow foaming agent thiab NC white foaming agent. AC yuav tso tawm ntau cov cua sov thaum lub sij hawm decomposition, ua rau yellowing ntawm cov khoom thiab ib tug me me ntawm ammonia tsw thaum decomposition; NC absorbs cua sov thaum lub sij hawm decomposition, thiab decomposition yog tasteless. Yog li ntawd, ob hom khoom ua npuas ncauj feem ntau yog siv hauv kev sib koom tes.
Tus nqi ntawm tus neeg sawv cev foaming tsis txaus, qhov sib piv foaming tsawg, cov khoom muaj ob peb npuas thiab siab ceev;
Yog tias siv ntau tus neeg sawv cev ua npuas dej, lub zog yaj yuav ua rau qis, cov khoom lag luam nyuaj rau kev tsim, thiab ntu ua npuas ncauj yog yooj yim los tsim npuas; Tshaj li qhov ntau yam, cov khoom ntom ntom yuav loj dua;
Yellow foaming tus neeg saib xyuas yog ntau dua, tus neeg sawv cev dawb foaming tsawg dua, thiab cov npuas loj thiab puag ncig yog yooj yim tshwm sim hauv ntu.
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. Hauv kev xyaum ua ntau lawm, peb yuav tsum dhau los ntawm kev sim rov ua dua, 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.
