I-polyurethane foam iyi-polymer yamangqamuzana aphezulu.Umkhiqizo owenziwe nge-polyurethane ne-polyether oxutshwe ngobuchule.Kuze kube manje, kukhona izinhlobo ezimbilievumelana nezimo igwebu futhiqina igwebu emakethe.Phakathi kwazo, igwebu eliqinile yi-a iseli elivaliweisakhiwo, ngenkathi ievumelana nezimo igwebu iiseli elivuliwe isakhiwo.Izakhiwo ezahlukene zinemikhakha ehlukene yokusetshenziswa.
Tumsebenzi we-polyurethane foam
PIgwebu le-oliurethane lingadlala indima yokuvimbela.Noma ngabe kunjaloqina igwebu nomaevumelana nezimo igwebu, impahla yinhle futhi ingavinjelwa.Yiqiniso, kungase kube futhiukufakwa komsindo umphumela, futhi ingasetshenziswa kwezinye izinkambu ukuhlukanisa imisindo ethile kahle kakhulu.I-conductivity ephansi ye-thermal kanye nokusebenza okuhle kwe-thermal insulation.Ku-foam eqinile ye-polyurethane foam, kukhona impahla eneukufakwa kwe-thermal futhiungangeni manzi imisebenzi, okunciphisa conductivity ezishisayo.Kwezinye izinkambu, i-ejenti yokufutha ye-thermal ephansi iyadingeka, kanti ezinye izinto ezinamathelayo azifanelekile ukusetshenziswa.
Iisicelo i-polyurethane foam
Ukonga amandla nokuvikelwa kwemvelo.Njengokugcwalisa, igebe lingagcwaliswa ngokuphelele, futhi ukusebenza kokunamathela kungafinyelelwa.Ngemva kokuphulukiswa, inganamathela ngokuqinile futhi ibe nempilo ende yesevisi.
Ukucindezela kanye nokushaqeka.Lapho igwebu le-polyurethane seliphulukisiwe ngokuphelele, ngeke kube nokuqhekeka, ukugqwala nokuxebuka.Inohlu olubanzi lwezinhlelo zokusebenza kanye nezinhlobonhlobo zokusetshenziswa.Ingasetshenziswa emandleni amasha, embonini yezempi, ukwelashwa kwezokwelapha, izindiza, imikhumbi, i-electronics, izimoto, izinsimbi, izinsiza zikagesi, isitimela esinesivinini esikhulu, njll., nge-conductivity ephansi, ukumelana nokushisa okuhle, nokugcinwa kokushisa.Isetshenziswa kuma-electronics, ukunikezwa kwamandla nezinye izinkambu, ingamelana ngokuphumelelayo nemvelo yokushisa okuphezulu futhi isebenzise ukusebenza kokushisa okushisayo.
I-soundproofing kanye ne-insulating.Lapho igwebu le-polyurethane seliphulukisiwe ngokuphelele, lingafaka umswakama kakhulu futhi lingangeni manzi.Ngisho nasendaweni emnyama futhi enomswakama, ngeke kube nezinkinga.
Izinkinga ezivamile kanye nezinyathelo zokuvimbela ze-polyurethane foam
| Inkinga Engajwayelekile | Izimbangela Ezingenzeka | Izinyathelo Zokuvimbela |
| amagwebu avuzayo |
| 1. Lungisa ipulaki yegwebu kanye nendandatho ye-silicone yegwebu emgqonyeni wangaphandle ukuze uqinisekise ukuthi ipulaki yegwebu nomgqomo kuvalwe ngokuqinile. 2. Lungisa isilinganiso sesixazululo sesitoko esinamagwebu. |
| ibhamuza | 1. Igwebu eliningi kakhulu. 2. Isikhunta esinegwebu siyaxega futhi sikhubazekile ngenxa yokuphoqwa amagwebu. | 1. Lungisa inani legwebu 2. Lungisa noma shintsha isikhunta esinamagwebu |
| vacuoles | 1. Inani legwebu liphansi 2. Isilinganiso esingalungile sesisombululo sesitoko kanye ne-agent egwebulayo ephansi 3. Ijubane elikhihliza amagwebu lishesha kakhulu, 4. Ukugeleza koketshezi olugwebuzelayo emgqonyeni kude kakhulu. | 1. Khulisa inani legwebu 2. Lungisa isilinganiso 3. Lungisa isivinini esikhihliza amagwebu 4.Shintsha indawo yembobo yomjovo noma wandise indawo yomjovo ukuze unciphise ukugeleza koketshezi olunegwebu emgqonyeni. |
| akunamatheli | 1. Kukhona amafutha ebusweni bethangi elingaphakathi 2. Ubushelelezi bobuso bomugqa wangaphakathi noma udonga lwangaphakathi lokuhlinza luphakeme kakhulu, futhi ukunamathela koketshezi lwebhamuza kubi 3. Izinga lokushisa le-ambient liphansi kakhulu, futhi izinga lokushisa elingaphezulu lesisombululo sesitoko, isikhunta, umgqomo negobolondo liphansi kakhulu. | 1. Hlanza amabala amafutha ngotshwala 2. Faka esikhundleni i-liner noma impahla yegobolondo, noma unciphise izimfuneko zokuphela komugqa (udonga lwangaphakathi lwegobolondo) 3. Khulisa izinga lokushisa le-ambient futhi ushise kuqala uhlelo lokugwedla. |
| Ingxube ye-inhomogeneous | 1. Umfutho womjovo uphansi kakhulu 2. Isixazululo sesitoko singcolile kakhulu noma izinga lokushisa liphansi kakhulu, futhi ukugeleza akuzinzile. | 1. Khulisa ingcindezi yomjovo futhi uqinise ukuxutshwa kwezinto ezimnyama nezimhlophe 2. Hlunga ikhambi lesitoko bese uhlanza ikhanda lesibhamu esinamagwebu njalo.Khulisa izinga lokushisa lesixazululo sesitoko. |
| shwabana | 1. Isilinganiso esingalungile sesisombululo sesitoko 2. Ukuxubana okungalingani | 1. Lungisa isilinganiso 2. Hlanganisa ngokulinganayo |
