Koj paub ntau npaum li cas txog PVC foaming regulators

1, Ua npuas ncauj mechanism:

Lub hom phiaj ntawm kev ntxiv ultra-siab molecular hnyav polymers rau PVC ua npuas ncauj khoom yog los txhawb cov yas ntawm PVC;Qhov thib ob yog los txhim kho cov yaj lub zog ntawm cov ntaub ntawv PVC ua npuas ncauj, tiv thaiv kev sib koom ua ke ntawm npuas, thiab tau txais cov khoom zoo sib xws;Qhov thib peb yog los xyuas kom meej tias cov yaj muaj fluidity zoo, thiaj li yuav tau txais cov khoom nrog zoo tsos.Vim qhov sib txawv ntawm cov khoom, cov khoom siv, cov txheej txheem, cov khoom siv raw, thiab cov tshuab lubrication siv los ntawm cov tuam txhab ua npuas ncauj sib txawv, peb tau tsim ua npuas ncauj regulators nrog kev ua haujlwm sib txawv kom tau raws li qhov sib txawv ntawm cov neeg siv khoom.

1. Kev txhais cov khoom ua npuas ncauj

Foamed yas, tseem hu ua ua npuas ncauj yas, yog cov khoom sib xyaw nrog cov yas ua cov khoom tseem ceeb thiab muaj ntau cov npuas, uas tuaj yeem hais tau tias muaj roj.

2. Kev faib tawm ntawm cov ntaub ntawv Foam Sheet

Raws li qhov sib txawv foaming ratios, nws tuaj yeem muab faib ua cov foaming siab thiab qis foaming, thiab raws li lub hardness ntawm foaming lub cev kev ntxhib los mos, nws tuaj yeem muab faib ua ib qho nyuaj, semi nyuaj thiab mos foams.Raws li cov qauv ntawm tes, nws tuaj yeem muab faib ua cov cell foams thiab qhib cell foams.Feem ntau siv PVC ua npuas ncauj ntawv belongs rau hard kaw cell uas tsis muaj npuas daim ntawv.

3. Daim ntawv thov ntawm PVC ua npuas ncauj ntawv

PVC ua npuas ncauj ntawv muaj qhov zoo xws li cov tshuaj tiv thaiv corrosion, huab cua tsis kam, thiab nplaim hluav taws, thiab tau siv dav hauv ntau yam, suav nrog cov khoom vaj huam sib luag, cov cim, cov ntawv tshaj tawm, cov khoom faib, lub tsev boards, rooj tog zaum, thiab lwm yam.

4. Cov ntsiab lus tseem ceeb rau kev ntsuas qhov zoo ntawm cov ntawv ua npuas ncauj

Rau cov ntaub ntawv foaming, qhov loj thiab uniformity ntawm npuas pores yog qhov tseem ceeb cuam tshuam rau qhov zoo ntawm daim ntawv.Rau cov ntawv ua npuas ncauj uas tsis tshua muaj siab, cov npuas pores yog me me thiab sib xws, cov ntawv ua npuas ncauj muaj qhov zoo toughness, siab zog, thiab zoo nto zoo.Los ntawm qhov kev xav ntawm kev txo qhov ntom ntawm cov ntaub ntawv ua npuas ncauj, tsuas yog cov npuas me me thiab zoo ib yam ua npuas ncauj muaj qhov ua tau ntawm kev txo qis ntxiv, thaum ua npuas ncauj loj thiab tawg yog qhov nyuaj los txo qhov ntom.
