Kupfapfaidza Polyurethane PamaContainer Chaizvoizvo Kuve Nekupisa Kwekupisa?

Rudzi rwakajairika rweimba yemidziyo ndeyekupa pekugara kune vashandi panzvimbo yekuvaka.Vanogona kugara muchirimo chinopisa kana kuti muchando chinotonhora here?Hakuzotonhora here kana kupisa?Muchokwadi, ingave chirimo kana chando, midziyo inogona zvakare kuiswa insulated.Kana musinganditendi, ingoverenga!

Iyo mudziyo pachayo haina basa rekupisa kupisa.Muchando kunotonhora uye kunopisa muzhizha.Muchirimo, kunze tembiricha iri 38 °, uye tembiricha mukati mudziyo kazhinji yakakwirira kusvika 42 °.Naizvozvo, iyo thermal insulation layer yakakosha.Mushure mokunge imba yemidziyo yakagadziriswa, zvakakosha kuwedzera chigadziko chekupisa uye kuisa zvivako zvemhepo.

Thermal insulation layer pano inopfapfaidzwa ne polyurethane hard foam.Zvechokwadi, kune mamwe maitiro ekudzivirira kupisa, akadai semafuta ekudzivirira mvere, rock wool board, silicate board, etc. Sarudzo inonyanya kuenderana nekushandisa kwako chaiko.

Saka chii chinonzi polyurethane spraying?

Polyurethane sprayinginoreva kushandisa yakakosha polyurethane spraying muchina kupfapfaidza polyurethane mbishi zvinhu pasi pekuita kwezvakasiyana-siyana zvekuwedzera senge anopupuma ejenti, catalysts, uye mirazvo retardants, kuburikidza nekumhanya-mhanya uye kutenderera kwechisimba mukamuri yekusanganisa ine nzvimbo diki, uye wopfuura. kuburikidza nemuromo wepfuti yespray.A high molecular polymer inoumba madonhwe emhute yakanaka uye inopfapfaidza zvakaenzana pamusoro pechinhu.

Ndezvipi zvakanakira kumwaya polyurethane pamidziyo?

1. Thermal insulation, kushanda kwepamusoro uye kuchengetedza simba.

Thermal conductivity ye polyurethane thermal insulation material yakaderera, uye kuchengetedza kwekushisa uye kupisa kwekudzivirira kwekushisa kwakanaka, izvo zvisingaenzaniswi nezvimwe zvinhu zvinopisa zvinopisa.Muzvivakwa zvekugara, polyurethane rigid foam inoshandiswa sedenga rekudzivirira mvura uye rinodzivirira kupisa, ukobvu hwaro hunongova chikamu chimwe chete muzvitatu chezvigadzirwa zvechinyakare, uye kupikisa kwayo kupisa kunopeta katatu pane izvo.Nekuti thermal conductivity ye polyurethane ingori 0.022 ~ 0.033W/(m*K), iyo yakaenzana nehafu yeiyo extruded board, uye ndiyo yakadzikira yekupisa yekuvharisa coefficient pakati pezvinhu zvese zvinopisa zvinopisa zvino.

2. Mutoro wedenga wakareruka.

Iyo polyurethane insulation zvinhu ine yakaderera density uye huremu huremu, saka mutoro uri padenga uye madziro wakareruka.Denga rekupfapfaidza polyurethane thermal insulation material chikamu chechina chemaitiro echinyakare ekupfigira denga, izvo zvakakosha zvikuru kuvandudza chimiro cheimba uye kuderedza mutengo wekuvaka, saka inonyanya kukodzera kune yakakura-refu uye yakatetepa-yedenga zvivakwa. .

3. Kuvaka kuri nyore uye kufambira mberi kunokurumidza.

Iyo tekinoroji pano ndeye polyurethane spraying uye pa-saiti foaming, iyo inogona kushanda pane chero yakaoma denga kuvaka, iyo yakapetwa kagumi inoshanda kupfuura kuisa zvechinyakare zvinhu.Inoderedzawo kuwanda kwevashandi, inovandudza nharaunda yekushanda, uye inoderedza kusvibiswa kwezvakatipoteredza.

Iyo pa-saiti inopupuma yekuwedzera vhoriyamu ye polyurethane insulation zvinhu ndeye 15-18 nguva, saka huwandu hwekufambisa hwemidziyo idiki.Zvinoenderana nenhamba, inogona kuderedza mutengo wekutakura mota neinopfuura 80% kana ichienzaniswa nekushandiswa kwezvinhu zvechinyakare, uye zvakare inoderedza zvakanyanya kuwanda kwebasa rekufamba kwakamira panzvimbo yekuvaka.

4. Unhu hwakanaka hweinjiniya, hupenyu hurefu hwebasa uye mutengo wakaderera

Polyurethane insulation zvinhu ndeye dense microporous foam ine yakavharwa sero chiyero chinodarika 92%.Iine kutsetseka kweganda uye chinhu chakanakisa chisingapindiki.Iyo yakananga yekupfapfaidza yekuumba tekinoroji inoshandiswa mukuvaka kuita iyo yakazara kuumbwa pasina seams Iyo yakakwana impermeability inobvisa zvakanyanya mukana wepadenga remvura kupinda nepakati seams.

Iyo polyurethane thermal insulation material inogona kusungirirwa zvakasimba kune base layer, uye simba rayo rekubatanidza rinogona kudarika simba rekubvarura refuro pacharo, kuitira kuti polyurethane thermal insulation material uye base layer zvibatanidzwe, uye delamination haisi nyore kuitika. uye kupinda kwemvura pamwe chete ne interlayer kunodziviswa.Traditional thermal insulation materials zviri nyore kutora mvura uye unyoro, uye hupenyu hwebasa hwezvakajairwa mvura membranes ipfupi kwazvo, uye dzinofanirwa kugara dzichigadziriswa nekutsiviwa;nepo hupenyu hwesevhisi hwe polyurethane thermal insulation materials inogona kusvika makore anopfuura gumi, uye mutengo wekuchengetedza wakachengetwa panguva ino wakakura kwazvo.
