Yiziphi izindlela zokusebenzisa izilawuli ze-PVC foaming?

Kufomula ye-PVC foaming, ukuze kutholakale umkhiqizo wesakhiwo samaseli ofana kakhulu, omncane, futhi ozimele, ngaphezu kokusebenzisa ama-foaming modifiers njengezinsiza zokucubungula ze-ACR, ama-PVC foaming modifiers nawo asetshenziswa kule fomula. Ngezinye izikhathi, ama-foaming accelerators njenge-metal oxides njenge-zinc oxide kanye ne-lead oxide, usawoti we-organic acid njenge-zinc stearate, kanye ne-urea derivatives nawo ayangezwa (ukulungisa izinga lokushisa lokubola kwe-foaming agent). Umthamo we-foaming regulator uvame ukuba ngu-4% -8% (ngokusekelwe kokuqukethwe kwe-resin iyonke), okudingeka kuhambisane ngokuguquguqukayo nama-foaming agents (njenge-AC yellow foaming agent, i-NC white foaming agent). Ukukhiqizwa kwamapuleti aminyene kudinga ukwanda kwesilinganiso se-NC foaming agent yokushisa okuphansi (isilinganiso esijwayelekile sezingxenye ezingu-1.2 NC+0.5 AC) ukuze kugwenywe ukukhishwa kwegesi egxilile esigabeni sakamuva okuholela ekuqhekekeni kwe-foam; Ukulawulwa kobuningi kudinga ukulinganisela ukukhiqizwa kwegesi kanye nokushisa kokubola.
Isilawuli se-PVC foaming empeleni siyi-polymer ye-acrylate lotion. Inazo zonke izici zezinsiza zokucubungula i-PVC, kodwa isisindo sayo sama-molecule siphakeme kakhulu kunesezinsiza zokucubungula i-PVC. Enqubweni ye-PVC foaming, ukwengeza isilawuli se-PVC foaming kungandisa amandla okuncibilika kwemikhiqizo ye-PVC, ngaleyo ndlela kuvimbele ukuhlangana kwamabhamuza nokuthola imikhiqizo ye-PVC foam ene-foam efanayo. Ngesikhathi esifanayo, kungakhuthaza futhi ukwenziwa kwe-PVC ipulasitiki futhi kuqinisekise ukuthi ukuncibilika kunokugeleza okuhle.
Uma ukhetha ama-modifier e-PVC foam, kufanele kuqashelwe ukusebenzisa ama-modifier ahlukene e-foam e-PVC anamazinga ahlukene e-polymerization, njenge-PVC-700, i-PVC-800, kanye ne-PVC-1000. Imikhiqizo ehlukene, njengamabhodi e-foam, amabhodi amakhulu e-foam, amabhodi e-foam amancane, amabhodi e-foam epulasitiki yokhuni, amabhodi e-foam epulasitiki eholayo, njll., idinga ukusetshenziswa kwama-modifier ahlukene e-foam. Ngenxa yokuthi ama-ejenti e-foam e-PVC nawo angama-acrylic compounds anezakhiwo zokusiza ekucubunguleni, kufanele futhi kuqashelwe ibhalansi yokugcoba yangaphakathi neyangaphandle yefomula lapho uwasebenzisa. I-Bangtai Petrochemical Foam Regulator ihlangabezana nezidingo zakho ezahlukahlukene zemikhiqizo. Ukuze uthole eminye imibuzo yomkhiqizo mayelana nabalawuli be-foam be-PVC, sicela ukhululeke ukusishayela ucingo!
