Iimpawu eziphambili kunye nokuhlelwa kokusetyenziswa kwabalawuli be-foam:

1, umlawuli we-PVC okhupha amagwebu
Iimpawu zokusebenza
Ngokusebenzisa uyilo oluphezulu kakhulu lwe-molecular weight (ezifana nee-acrylic esters) ukuphucula amandla e-PVC melt, ukuthintela ukudibana kwamaqamza, kunye nokwenza isakhiwo esifanayo se-honeycomb (ububanzi beseli yi-0.1-0.5mm).
Khuthaza ukwenziwa kweplastiki yePVC, ukulinganisela ukuhamba kwamanzi okunyibilika kunye noxinano lwefoam, kwaye uphucule ukukhazimla komphezulu wemveliso.
Iimodeli eziqhelekileyo ziquka i-HF-100, i-ZB-530, i-P533J, njl. Ezinye iimodeli zinokwenziwa ngokwezifiso ukuze zilungele ubushushu bokubola kunye nesantya sokuveliswa kwegesi.
Iimeko zesicelo
Iimveliso zefoam zePVC eziqinileyo ezifana neebhodi zokwakha, iibhodi zentengiso, kunye neepayipi, ezinomlinganiselo wereferensi we-4-8.
Ukufutha kwe-sole kufuna ukulungiswa kokufana kwemingxuma ye-foam, kwaye ezinye iimveliso zenzelwe ngokukodwa ukufutha i-foam enoxinano olukhulu.
2, umlawuli we-polyurethane foam
Iimpawu zokusebenza
Njengesixhobo sokufaka amagwebu okanye isizinzisi, ilawula ulwakhiwo lweseli evulekileyo/evaliweyo ye-PU soft foam ukuphucula ukuqina kunye nokufana koxinano.
Iimeko zesicelo
Ukuveliswa kwefoam enamandla okumelana noxinzelelo, iglu yefoam kunye nezixhobo zezihlangu kufuneka zisetyenziswe kunye nearhente yokwenza amagwebu.
3, Uthelekiso loBugcisa
Zahlukile kwii-nucleating agents: ii-foam regulators zigxila kulawulo lwe-melt rheological, ngelixa ii-nucleating agents (ezifana ne-nano calcium carbonate) ziphucula ngokuthe ngqo ukuveliswa kwee-foam pores.
Isiphumo sokusebenzisana: Xa isetyenziswa kunye ne-hydrotalcite, inokuphucula uzinzo lobushushu kwaye inciphise iziphene zomphezulu.
