Cov teebmeem ntawm PVC foaming regulators rau ntawm cov qauv pore ntawm cov khoom yog dab tsi?

Tus tswj kev ua npuas ncauj uas tsim los ntawm Bontecn Group Tuam Tshoj cuam tshuam ncaj qha rau kev tsim, kev ruaj khov, thiab qhov kawg ntawm cov qhov ua npuas ncauj los ntawm kev tswj cov khoom ntawm cov polymer yaj. Cov tsos mob tshwj xeeb yog raws li nram no:
1. Kev sib npaug thiab kev ua kom zoo ntawm cov qhov ua npuas ncauj
Txhim kho lub zog thiab elasticity ntawm cov yaj, txhawb kev faib tawm ntawm cov roj hauv PVC yaj, tsim cov micropores ywj pheej (txoj kab uas hla 0.1-0.5 hli), thiab txo qhov teeb meem ntawm kev sib xyaw ua ke lossis coarsening ntawm cov npuas. Tib lub sijhawm, ua kom zoo dua qhov sib koom ua ke ntawm cov yaj kom ntseeg tau tias cov phab ntsa cell tuaj yeem tiv taus lub zog roj thiab tswj kev ruaj khov ntawm cov qauv kaw cell.
2. Kev tswj qhov ceev thiab qhov loj ntawm cov cell
Cov tshuaj yuav tsum tau sib phim kom raug: qis dhau (<4phr) ua rau lub zog yaj tsis txaus, ua rau npuas tawg lossis nto tawg; Yog tias nws siab dhau (>8phr), nws yuav ua rau lub zog yaj ntau dhau, tiv thaiv kev nthuav dav ntawm cov npuas, thiab hloov chaw ua rau qhov ceev ntawm cov khoom nce ntxiv. Qhov hnyav molecular siab dua (xws li 530 qauv), qhov me me dua qhov hws thiab qhov ceev qis dua, tab sis nws rhiab heev rau qhov kub ua tiav.
3. Kev tiv thaiv qhov tsis zoo thiab kev txhim kho cov qauv
Txhawm rau tiv thaiv cov npuas tsis zoo (xws li cov npuas ntev lossis qhov muag ntses), nws yog qhov tsim nyog los sib koom tes lubrication system thiab cov txheej txheem kub: kev swb sab nraud ntau dhau yuav txo qhov siab yaj thiab ua rau qhov tsis sib xws ntawm qhov ceev hauv zos; Kev hloov pauv kub ntawm ± 5 ℃ tuaj yeem cuam tshuam qhov sib xws ntawm cov qhov hws thiab xav tau ntxiv cov khoom hloov kho xws li zinc stearate rau kev ntsuas.
4. Kev hloov pauv tau yooj yim
Qhov kev xaiv ntawm tus qauv (xws li KF-100) rau ntau hom khoom (xws li cov ntawv PVC tawv lossis cov ntaub ntawv khau mos) cuam tshuam ncaj qha rau cov qauv pore: rau cov khoom mos, xav tau tus tswj hwm tshwj xeeb kom tsis txhob ua rau daim tawv nqaij blistering thiab txhim kho qhov elasticity ntawm tactile.
