Prepolymer nzira:
Iyo prepolymer foaming process inosanganisira kutanga kugadzirira prepolymer kubva (white component) uye (black component). Zvadaro, mvura, catalyst, surfactant, uye zvimwe zvinowedzera zvinowedzerwa kune prepolymer uye zvinosanganiswa pasi pepamusoro-zvinokuchidzira kuti zviputse furo. Mushure mekurapa, inochembera pane imwe tembiricha.
Semi{{0}Prepolymer Method:
Semi-prepolymer foaming process inosanganisira kutanga kugadzira prepolymer kubva muchikamu chepolyether polyol (white component) uye diisocyanate (black component). Zvadaro, chikamu chasara chepolyether kana polyester polyol, diisocyanate, mvura, catalyst, surfactant, uye zvimwe zvinowedzera zvinowedzerwa uye zvinosanganiswa pasi pepamusoro-zvinokuchidzira kuti zviputse furo.
Imwe{{0}Nhanho Yokupupa Furo:
Mukuita uku, polyether kana polyester polyol (white component) uye polyisocyanate (black component), mvura, catalyst, surfactant, foaming agent, uye zvimwe zvinowedzera zvinowedzerwa mudanho rimwe chete uye zvinosanganiswa pasi pepamusoro-kukurumidzira kusati kwapupuma furo.
Imwe{{0}nhanho yekupupa furo ndiyo inonyanya kushandiswa. Imwe nzira ndeye kupupa kwemaoko, iyo iri nyore. Nyatsoyera zvinhu zvose zvakabikwa, zviise mumudziyo, uye pakarepo uzvisanganise zvakakwana. Wodira musanganiswa muforoma kana nzvimbo inoda kuzadzwa nepurasitiki yefoam. Cherechedza: Paunenge uchiyera, iva nechokwadi chekuwedzera polyisocyanate (chinhu chitema) chekupedzisira.
Rigid polyurethane foam inowanzoputirwa nekamuri tembiricha, uye maitiro ekuumba ari nyore. Zvichienderana nedhigirii remakanika mukuvaka, inogona kukamurwa kuita furo remanyorero uye mechanic foaming; zvichibva pakumanikidzika panguva yekupupuma furo, rinogona kupatsanurwa kuita-kupupuma furo uye kuderera-kupupuma furo; zvichibva panzira yekuumba, inogona kukamurwa kuita yekukanda furo nekupfapfaidza kupupa.
