I-polyurethane foam iyi-polymer yamangqamuzana aphezulu.Umkhiqizo owenziwe nge-polyurethane ne-polyether oxutshwe ngobuchule.Kuze kube manje, kunezinhlobo ezimbili zegwebu eliguquguqukayo kanye negwebu eliqinile emakethe.Phakathi kwazo, i-foam eqinile iyisakhiwo seseli evaliwe, kuyilapho i-foam eguquguqukayo iyisakhiwo se-open-cell.Izakhiwo ezahlukene zinemikhakha ehlukene yokusetshenziswa.
Tumsebenzi we-polyurethane foam
Igwebu le-polyurethane lingadlala indima yokubhafa.Kungakhathaliseki ukuthi igwebu eliqinile noma igwebu eliguquguqukayo, impahla yinhle futhi ingavinjelwa.Kunjalo, ingaba nomthelela wokuvala umsindo, 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 into ene-thermal insulation kanye nemisebenzi engangeni manzi, enciphisa ukuqhutshwa kokushisa.Kwezinye izinkambu, i-ejenti yokufutha ye-thermal ephansi iyadingeka, kanti ezinye izinto ezinamathelayo azifanelekile ukusetshenziswa.
Iisiceloi-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, lingaba 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 siwohloka ngokuphoqelela ngesikhathi sokukhihliza amagwebu. | 1. Lungisa inani legwebu2.Lungisa noma shintsha isikhunta esinamagwebu |
| vacuoles | 1. Inani legwebu liphansi2.Isilinganiso esingalungile sesixazululo sesitoko kanye ne-ejenti enegwebu eliphansi3.Ijubane lokukhihliza amagwebu lishesha kakhulu, 4. Ukugeleza koketshezi olugwebuzelayo emgqonyeni kude kakhulu. | 1. Khulisa inani legwebu2.Lungisa isilinganiso3.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 elingaphakathi2.Ubushelelezi bendawo yomugqa wangaphakathi noma udonga lwangaphakathi lokuhlinza luphakeme kakhulu, futhi ukunamathela koketshezi lwebhamuza kubi3.Izinga lokushisa le-ambient liphansi kakhulu, futhi izinga lokushisa elingaphezulu lesixazululo sesitoko, isikhunta, umgqomo negobolondo liphansi kakhulu. | 1. Hlanza amabala amafutha ngotshwala2.Shintshanisa ulayini noma impahla yegobolondo, noma unciphise izimfuneko zokuqeda phezulu komugqa (udonga lwangaphakathi lwegobolondo)3.Khulisa izinga lokushisa le-ambient futhi ushise kuqala isistimu egcwele amagwebu. |
| Ingxube ye-inhomogeneous | 1. Umfutho womjovo uphansi kakhulu2.Isixazululo sesitoko singcolile kakhulu noma izinga lokushisa liphansi kakhulu, futhi ukugeleza akuzinzile. | 1. Khulisa ingcindezi yomjovo futhi uqinise ukuxutshwa kwezinto ezimnyama nezimhlophe2.Hlunga isixazululo sesitoko bese uhlanza ikhanda lesibhamu esinamagwebu njalo.Khulisa izinga lokushisa lesixazululo sesitoko. |
| shwabana | 1. Isilinganiso esingalungile sesisombululo sesitoko2.Ukuxuba okungalingani | 1. Lungisa isilinganiso2.Hlanganisa ngokulinganayo |
| ukuminyana okungalingani | 1. Ukuxubana okungalingani2.Ukugeleza koketshezi olugwebu ohlangothini ngalunye emgqonyeni kude kakhulu | 1. Hlanganisa ngokulinganayo2.Shintsha indawo yembobo yomjovo noma ukhuphule indawo yomjovo ukuze unciphise ukugeleza koketshezi olunegwebu emgqonyeni. |
| ukuguquguquka | 1. Isikhathi sokuguga asanele2.Amandla wempahla yegobolondo akwanele ukushwabana nokukhubazeka | 1. Nweba isikhathi sokuguga2.Thuthukisa ukumelana nokuncipha kwezinto |
