Ziziphi iindlela zokusebenzisa abalawuli be-PVC foaming?

Kwifomula ye-PVC foaming, ukuze kufunyanwe imveliso yesakhiwo seseli efanayo, ecolekileyo, nezimeleyo, ukongeza ekusebenziseni izilungisi ze-foaming ezifana nezixhobo zokucubungula i-ACR, izilungisi ze-PVC foaming zihlala zisetyenziswa kwifomula. Ngamanye amaxesha, izilungisi ze-foaming ezifana ne-metal oxides ezifana ne-zinc oxide kunye ne-lead oxide, iityuwa ze-organic acid ezifana ne-zinc stearate, kunye ne-urea derivatives nazo zongezwa (ukulungisa ubushushu bokubola kwe-agent ye-foaming). Umthamo we-foaming regulator udla ngokuba yi-4% -8% (ngokusekelwe kumxholo we-resin iyonke), ekufuneka ihambelane ngokuguquguqukayo nee-agent ze-foaming (ezifana ne-AC yellow foaming agent, i-NC white foaming agent). Ukuveliswa kweepleyiti ezixineneyo kufuna ukonyuka kwenani le-NC foaming agent yobushushu obuphantsi (umlinganiselo oqhelekileyo we-1.2 parts NC+0.5 parts AC) ukuthintela ukukhutshwa kwegesi exineneyo kwinqanaba lamva elikhokelela ekwaphukeni kwe-foam; Ulawulo loxinano lufuna ukulinganisela ukuveliswa kwegesi kunye nobushushu bokubola.
I-PVC foaming regulator yi-acrylate lotion polymer eneneni. Inazo zonke iimpawu ze-PVC processing aids, kodwa ubunzima bayo be-molecular buphezulu kakhulu kunobo be-PVC processing aids. Kwinkqubo ye-PVC foaming, ukongeza i-PVC foaming regulator kunokunyusa amandla okunyibilika kweemveliso zePVC, ngaloo ndlela kuthintelwe ukudibana kwamaqamza nokufumana iimveliso ze-PVC foam ezine-foam efanayo. Kwangaxeshanye, inokukhuthaza ukwenziwa kwe-PVC ibe yiplastiki kwaye iqinisekise ukuba i-melt inokuguquguquka okuhle.
Xa ukhetha izilungisi ze-PVC foam, kufuneka kuqwalaselwe ukusebenzisa izilungisi ze-foam ezahlukeneyo ze-PVC ezinamaqondo ahlukeneyo e-polymerization, njenge-PVC-700, i-PVC-800, kunye ne-PVC-1000. Iimveliso ezahlukeneyo, ezifana neebhodi ze-foam, iibhodi ezixineneyo ze-foam, iibhodi ze-foam zeplastiki zomthi, iibhodi ze-foam zeplastiki ezikhokelayo, njl.njl., zifuna ukusetyenziswa kwezilungisi ze-foam ezahlukeneyo. Ngenxa yokuba ii-arhente ze-PVC foam nazo ziyi-acrylic compounds ezineempawu zoncedo lokucubungula, kufuneka kuqwalaselwe nokulinganisela kokuthambisa kwangaphakathi nangaphandle kwefomyula xa usebenzisa zona. I-Bangtai Petrochemical Foam Regulator ihlangabezana neemfuno zakho ezahlukeneyo zeemveliso. Ukuze ufumane imibuzo engaphezulu malunga nee-PVC foam regulators, nceda uzive ukhululekile ukusitsalela umnxeba!
