1, isilawuli se-PVC foaming
Izici zokusebenza
Ngokusebenzisa umklamo wesisindo sama-molecule aphezulu kakhulu (njenge-acrylic esters) ukuthuthukisa amandla okuncibilika kwe-PVC, ukuvimbela ukuhlangana kwama-bubbles, nokwakha isakhiwo se-honeycomb esifanayo (ububanzi beseli bungu-0.1-0.5mm).
Khuthaza ukwenziwa kwepulasitiki kwe-PVC, ukulinganisela ukugeleza kokuncibilika kanye nobuningi be-foam, futhi uthuthukise ukucwebezela kobuso bomkhiqizo.
Amamodeli avamile afaka phakathi i-HF-100, i-ZB-530, i-P533J, njll. Amanye amamodeli angenziwa ngokwezifiso ukuze avumelane nokushisa kokubola kanye nesivinini sokukhiqizwa kwegesi.
Izimo zohlelo lokusebenza
Imikhiqizo ye-foam eqinile ye-PVC efana namabhodi okwakha, amabhodi okukhangisa, namapayipi, enesilinganiso sokubhekisela esingu-4-8.
Ukugqwala kwesisekelo kudinga ukulungiswa kokufana kwezimbobo ze-foam, futhi eminye imikhiqizo yenzelwe ngqo ukugqwala i-foam enobukhulu obuphezulu.
2, isilawuli se-polyurethane foam
Izici zokusebenza
Njenge-ejenti yokugqwala noma i-stabilizer, ilawula isakhiwo samaseli avulekile/avaliwe e-PU soft foam ukuze ithuthukise ukuqina kanye nokufana kobuningi.
Izimo zohlelo lokusebenza
Ukukhiqizwa kwe-foam enamandla okuqina, inhlaka ye-foam kanye nezinto zezicathulo kudinga ukusetshenziswa kanye ne-ejenti yokwenza amagwebu.
3, Ukuqhathanisa Kobuchwepheshe
Okuhlukile kuma-ejenti okubumba: abalawuli be-foam bagxila ekulawulweni kwe-rheological okuncibilikayo, kuyilapho ama-ejenti okubumba (njenge-nano calcium carbonate) ehlanza ngqo ukukhiqizwa kwama-foam pores.
Umphumela we-synergistic: Uma isetshenziswa kanye ne-hydrotalcite, ingathuthukisa ukuzinza kokushisa futhi inciphise amaphutha ebusweni.
