Polyurethane foam ndeye yakakwira molecular polymer.Chigadzirwa chakagadzirwa kubva ku polyurethane uye polyether iyo yakasanganiswa zvine hunyanzvi.Kusvika ikozvino, kune marudzi maviri eflexible furo uyerigid furo pamusika.Pakati pavo, furo rakaomarara ndiro a yakavharwa-serochimiro, panguva iyoflexible furo irivhura-sero chimiro.Zvimiro zvakasiyana zvine nzvimbo dzakasiyana dzekushandisa.
Tbasa re polyurethane foam
Polyurethane foam inogona kuita basa rekuchengetedza.Kana zviri izvorigid furo kanaflexible furo, zvinhu zvakanaka uye zvinogona kuvharwa.Zvechokwadi, inogonawo kuva nesound insulation Mhedzisiro, uye inogona kushandiswa mune mamwe minda kupatsanura mamwe manzwi zvakanaka.Low thermal conductivity uye yakanaka thermal insulation performance.Mune iyo yakaoma foam ye polyurethane foam, pane chinhu chinethermal insulation uyeisina mvura mabasa, izvo zvinoderedza thermal conductivity.Mune mamwe minda, yakadai yakaderera yekupisa conductivity inofuridza agent inodiwa, uye mamwe anonamira haana kukodzera kushandiswa.
Theapplication ye polyurethane foam
Kuchengetedza magetsi uye kuchengetedza kwezvakatipoteredza.Sekuzadza, gaka rinogona kuzadzwa zvakakwana, uye kuita kwekunamatira kunogona kuwanikwa.Mushure mekuporesa, inogona kunamatira zvakasimba uye ine hupenyu hurefu hwebasa.
Compression uye shockproof.Kana iyo polyurethane foam yanyatsopora, hapazove nekutsemuka, ngura uye peeling.Iine huwandu hwakawanda hwekushandisa uye huwandu hwakawanda hwekushandisa.Inogona kushandiswa musimba idzva, indasitiri yemauto, kurapwa, kubhururuka kwendege, ngarava, zvemagetsi, mota, zviridzwa, magetsi emagetsi, njanji inomhanya, nezvimwewo, ine yakaderera conductivity, yakanaka kupisa kupisa, uye kuchengetedza kupisa.Inoshandiswa mumagetsi, magetsi uye mamwe minda, inogona kurwisa zvakanyanya tembiricha nharaunda uye kuita thermal insulation performance.
Soundproofing uye insulating.Kana iyo polyurethane foam yapora zvachose, inogona kuve yakanyatso hunyoro-uchapupu uye kusapinda mvura.Kunyange munzvimbo ine rima uye ine mwando, hapazovi nematambudziko.
Matambudziko akajairika uye matanho ekudzivirira e polyurethane foam

| bubble | 1. Furo rakawandisa. 2. Iyo mold inopupa inosununguka uye yakakanganiswa nechisimba panguva yekupupa. | 1. Rongedza kuwanda kwefuro 2. Gadzirisa kana kutsiva mold inopupuma |
| vacuoles | 1. Kuwanda kwefuro kwakaderera 2. Kusakwana kwechiyero chemushonga wekugadzirisa uye yakaderera furo agent 3. Kubuda furo kunomhanya zvakanyanya, 4. Kuyerera kwemvura inopupuma mudhiramu kwakarebesa. | 1. Wedzera huwandu hwefuro 2. Gadzirisa reshiyo 3. Gadzirisa kumhanya kwefuro 4.Shandura nzvimbo yegomba rejekiseni kana kuwedzera nzvimbo yejekiseni kupfupisa kuyerera kwemvura inopupuma mudhiramu. |
| kwete kunamira | 1. Pane mafuta pamusoro petangi remukati 2. Kutsvedzerera kwepamusoro kwe liner yemukati kana madziro emukati ekuvhiya akanyanya kukwirira, uye kunamatira kwebubble fluid hakuna kunaka. 3. The ambient tembiricha yakanyanya kuderera, uye tembiricha yepasi ye stock solution, mold, barrel and shell yakanyanya kuderera. | 1. Geza mafuta mavara nedoro 2. Tsiva iro liner kana shell zvinhu, kana kuderedza zvinodiwa zvepadenga kupera kwe liner (yemukati madziro egoko) 3. Wedzera ambient tembiricha uye preheat iyo furo system. |
| Inhomogeneous musanganiswa | 1. Jekiseni pressure yakanyanya kuderera 2. Mushonga wekutengesa wakanyanya kusvibiswa kana kutonhora kwakanyanya kuderera, uye kuyerera hakuna kugadzikana. | 1. Wedzera kumanikidzwa kwejekiseni uye kusimbisa kusanganiswa kwezvinhu zvitema uye zvichena 2. Sefa mushonga westock uye uchenese musoro wepfuti unopupuma nguva nenguva.Wedzera kutonhora kweiyo stock solution. |
