Mokhoa oa ho thibela cavitation hopolyurethane foaming mochine
1. Laola ka thata karo-karolelano le molumo oa ente ea tharollo ea pele
Laola karo-karolelano ea thepa e ntšo, e kopantsoeng polyether le cyclopentane.Tlas'a boemo ba hore palo eohle ea ente e lula e sa fetohe, haeba karolo ea lintho tse ntšo e le khōlō haholo, cavitation e tla hlaha, haeba karolo ea lintho tse tšoeu e le khōlō haholo, li-bubble tse bonolo li tla hlaha, haeba karolo ea cyclopentane e le khōlō haholo, li-bubble. e tla hlaha, 'me haeba karolo e le nyane haholo, cavitation e tla hlaha.Haeba karolo ea thepa e ntšo le e tšoeu e sa leka-lekane, ho tla ba le ho kopanya ho sa tšoaneng le ho fokotseha ha foam.

Palo ea ente e lokela ho ipapisa le litlhoko tsa ts'ebetso.Ha palo ea ente e le tlase ho feta tlhoko ea ts'ebetso, sekhahla sa ho bopa foam se tla ba tlase, matla a tla ba tlase, esita le ketsahalo ea ho tlatsa li-vacuoles tsa incompact li tla etsahala.Ha molumo oa ente o phahame ho feta litlhoko tsa ts'ebetso, ho tla ba le katoloso ea bubble le ho lutla, 'me lebokose (lemati) le tla holofala.
2. Taolo ea mocheso oapolyurethane foaming mochineke senotlolo sa ho rarolla cavitation
Ha mocheso o phahame haholo, karabelo e ba mabifi 'me ho thata ho e laola.Ho bonolo ho hlaha hore ts'ebetso ea mokelikeli oa bubble o kentsoeng ka lebokoseng le leholo ha o tšoane.Mokelikeli oa bubble o kentsoeng qalong o bile le karabelo ea lik'hemik'hale, 'me viscosity e eketseha ka potlako,' me mokelikeli oa bubble o kentsoeng hamorao ha o e-s'o arabe.Ka lebaka leo, mokelikeli oa bubble o kentsoeng hamorao o ke ke oa sutumelletsa mokelikeli oa bubble o kentsoeng pele ho ea qetellong ea ts'ebetso e phophomang ea lebokose, e bakang cavitation ea lehae ka lebokoseng.
Lisebelisoa tse ntšo le tse tšoeu li lokela ho alafshoa ka mocheso o sa khaotseng pele o phophoma, 'me mocheso o phoroselang o lokela ho laoloa ho 18 ~ 25 ℃.Thempereichara ea sebōpi sa preheating ea thepa e foaming e lokela ho laoloa ho 30 ~ 50 ℃, 'me mocheso oa hlobo o phophomang o lokela ho laoloa pakeng tsa 35 ~ 45 ℃
Ha mocheso oa hlobo o phophomang o le tlase haholo, mokelikeli oa mokelikeli oa foam o fokola, nako ea ho folisa e telele, karabelo ha e phethehe, 'me cavitation e etsahala;ha mocheso oa hlobo o phophomang o phahame haholo, lesela la polasetiki le holofatsoa ke mocheso, 'me tsamaiso ea mokelikeli oa foam e arabela ka matla.Ka hona, mocheso oa hlobo e phophomang le mocheso o teng oa sebōpi se phophomang o tlameha ho laoloa ka thata.
Haholo-holo mariha, hlobo e phophomang, sebōpi sa preheating, sebōpi se phophomang, lebokose le monyako li tlameha ho futhumatsoa ka metsotso e fetang 30 hoseng ho hong le ho hong ha mohala o buloa.Ka mor'a ho foka ka nako e itseng lehlabula, tsamaiso ea ho foka e tlameha ho pholile.

Taolo ea Khatello ea Mochini oa Foaming oa Polyurethane
Khatello ea mochini o phunyang lekoeba e tlase haholo.Lintho tse ntšo, tse tšoeu le cyclopentane ha li kopane ka mokhoa o ts'oanang, tse bonahatsoang e le ho se leka-lekane ha foam ea polyurethane, li-bubble tse kholo tsa sebaka seo, ho phunyeha ha foam, le foam e bonolo ea sebakeng seo: li-streaks tse tšoeu, tse mosehla kapa tse ntšo li hlaha foam , foam e ile ea oa.Khatello ea ente ea mochini o phophomang ke 13 ~ 16MPa
