Foam gasket tepi

Polyurethane foam- Ichi hachisi chete imwe nzira yakachipa kusvika pakurara. Kazhinji pane kusanzwisisana kuti iyi ndiyo mhinduro yepasirese, uye mukupedzisira ivo vanosarudza zvinhu zvisina kukodzera kune rimwe basa. Ndanga ndichishanda nezvinhu izvi kwemakore mazhinji, uye ndinogona kutaura kuti ndizvo zvakanaka kusarudzaDura kubva pherurethane foam- Ichi chiitiko chose. Izvo zvakakosha kuti urege kufunga nezve humwe hunhu hwenyama, asiwo zvinhu zvezvakatipoteredza. Makore mashoma apfuura, takatarisana nedambudziko mukugadzirwa kwechimiro chakaomarara, uko standard status gassi dzakangogona kumira. Ipapo takachinjira ppu, asi, takasarudza kuumbwa kwaunoda kwenguva yakareba kusvikira tanyatsoita kuti kwete kungoomesa, asiwo porosity, pamwe neyakajeka yePolyurethane.

Chii chinonzi chimiro chePolyurethane foam uye chinoita sei?

Kutanga, ngatifungei kuti izvi zvinyorwa zvacho zvakawandisa.Poliuretan Foam- Iyi ipolymer foam yakawanikwa semhedzisiro yemakemikari maitiro pakati pePolyls uye isocymas. Kugadzirwa kwePolyurethane Foam kwakasiyana: kubva kuchinjika uye elastic kune zvakaoma uye elastic. Iyo inotenda kune dzakasiyana siyana dzekuwedzera uye chimiro,Materers kubva polyurethane foamIvo vanokwanisa kuita mabasa akasiyana-siyana: Kuisa chisimbiso, kuderera, kushamwaridzana kwenyama, uye kunyange kupisa uye kurira kwekunzwa. Izvo zvakakosha kuti unzwisise kuti 'polyurethane foam' pane kirasi yezvinyorwa, kwete chigadzirwa che homogeneous. Kune mhando dzakasiyana siyana dzinosiyana mukuwedzera, kuomarara, iko kupokana uye zvimwe paramita.

Kuumbwa kwePPU kunosanganisira kwete chete polymer zvikamu, asi zvakare zvinowedzera: mafirita (semuenzaniso, talc kana chalk), stabilizer, antioxidants, dhayixidhonts, dhayixida. Kuumbwa kwezvizhinji zvinobata zvinokanganisa zvivakwa zvechigadzirwa chekupedzisira. Semuenzaniso, kuwedzera talc inowedzera kuomarara uye inovandudza maitiro emuchina, uye antioxidanti inochengetedza zvinyorwa kubva mukuparadzwa pasi peiyo fungidziro yeiyo yereltraviolet radiation. Ini ndinokurudzira kugara ndichikumbira pasipoti yemhando kubva kumutengesi, uko kuumbwa kwezvinhu zvinoratidzwa zvakadzama.

Mhando dzemasitimu kubva pherurethane foam: sarudzo yemabasa akasiyana

Pane mhando dzakasiyanaZvikamu zvePolyurethane foamyakagadzirirwa zvinangwa zvakasiyana. Zvinonyanya kuitika: flatgasi, mhetegasi, gasichimiro chakaoma, uye kunyange chakakoshagasinezviyero zvakabatanidzwa zvine chisikwa. Sarudzo yerudzi inoenderana nejometry yekubatana, inodikanwa kusimba, uye mamiriro ekushanda.

Semuenzaniso, yekuisa chisimbiso mu hydraulic system, mhetegasiNekukwira kwakanyanya kune mafuta uye sol sol. Kugadzira midziyo yekudzikira mukugadzira mejini engineering, sarudzagasinekuderera kwezasi uye yakakwirira elasticity. Uye nekuda kwekunzwa kwekunzwa, sekuziva kwedu nemaindasitiri emhepo masisitimu aratidza, zvakanyatsokodzeragasiNechimiro chekumisa chinobudirira chinyatso nyora ruzha. Mukuita, kusanganiswa kwemhando dzakasiyana siyana kunowanzo kudiwa kuti uwane mhedzisiro yeruzivo.

Chii chekuteerera kune kana uchisarudza chimiro kubva polyurethane foam?

KusarudzaDura kubva pherurethane foam. Iyo density inosarudza simba rekuita uye kuramba kuti udzvinyirire. Kusimba kunokanganisa elasticity uye kugona kutsungirira mitoro. Iko kusvibisa pane mutoro kunoratidza kuti yakakura sei gasket ichamanikidzwa pasi pesimba rekumanikidzwa. Izvo zvakakosha kuti uve nechokwadi chekuti zvinyorwa zvinopesana nemhedzisiro yezvinhu zvazvinobata (Mafuta, Acids, Solventes, nezvimwewo).

Imwe pfungwa yakakosha ndeyekobvu yegeti yegeti. Inofanira kunyorerana kujekeswa pakati peiyo nzvimbo yakabikwa. Kunyanya kutetepa kuiswa hakuzopi kusimba kwakakodzera, uye gobvu zvakanyanya kunogona kutungamira mukupfuurika nekuparadzwa kwekutanga. Zvakakoshawo kufunga kuti nderudzi rwei rwekubatana zvinoshandiswa (semuenzaniso, kubatana kwefurati, kubatana, nezvimwewo). Kune imwe neimwe mhando yekubatanidza, yakakoshagasi.
