Iko kushandiswa kukuru kweiyo nyowani polyurethane zvinhu

Mazuva ano, polyurethane insulation material inozivikanwa kumunhu wese sechinhu chekuvhara, chinonyanya kushandiswa kuvharisa madziro, pombi yekumisa nzvimbo mbiri huru, senge pombi dzemafuta, mapaipi egasi uye kuvharisa madziro emba.

Polyurethane insulation simbi pombi inopesana nekushandiswa kwesimbi pombi seyekunze inodzivirira layer, ine simba rakawanda.Hazvisi nyore kukuvadza uye zvinogona kumira maitiro emutoro mukuru wepamusoro, kuitira kuti uwane hupenyu hurefu, pombi yesimbi jekete inoda kuva anti-corrosion treatment.

Rolling yekutsigira chimiro dhizaini inonzwisisika, rolling friction idiki, yakagadziriswa tsigiro simba yakaderedzwa, yayo mechanic yekuongorora musimboti iri nyore, kugadzikana kwepombi, chengetedzo yakagadziridzwa zvakanyanya.

Polyurethane insulation simbi pombi vacuum layer inobvisa zvachose kuvepo kwemhepo dhizaini yekupisa conduction uye kupisa convection, ichideredza zvakanyanya kurasikirwa kwekupisa.Kuenzaniswa nemhepo yakatsetseka chimiro, mune imwechete insulation ukobvu kunogona kuderedza kunze kwemadziro tembiricha 8-13° c.

Iyo vacuum mudziyo inogadzirisa zvachose dambudziko remukati memadziro ekunze simbi casing iri kuomeswa nyore nemhepo inopisa uye inonyorova, iyo inovandudza zvakanyanya hupenyu hwekushanda hwepombi yakananga yakavigwa steam.Hupenyu hwechigadzirwa hunowedzerwa kusvika kumakore makumi matatu.

Polyurethane insulation pombiinoshandiswa kune akasiyana-siyana emukati nekunze mapaipi, centralized kupisa mapaipi, epakati air-conditioning mapaipi, makemikari, mishonga uye mamwe maindasitiri pombi insulation, kutonhora kuchengetedza chirongwa.Ongororo ye polyurethane foam insulation pombi kubva pakuzvarwa kwe polyurethane synthetic zvinhu mumakore makumi matatu, yave seyakanakisa kupisa kwemafuta ekudzivirira uye kukurumidza kusimudzira, kushandiswa kwayo kunowedzera uye kwakawedzera, zvakanyanya nekuda kwekuvakwa kwayo kuri nyore, inochengetedza simba-inopokana-kuora maitiro. uye inoshandiswa muhuwandu hukuru hwekudziya kwakasiyana-siyana, firiji, mafuta, steam uye mamwe marudzi emapaipi.Inoshandiswa muhuwandu hukuru mumapaipi akasiyana-siyana ekudziya, kutonhora, mafuta uye kutapurirana kwemhepo, nezvimwe.

Zvikomborero zvehupfumi zvekushandiswa kwezvinhu zvitsva zve polyurethane

Insulation pipechinhu chakakosha chinokanganisa kuchengetedza kwesimba, kusimudzira uye kushandiswa kwepombi yekuisa mutomu kuri kuwedzera kutariswa nenyika dzepasirese.mushure memakore ekuma1970, nyika dzekunze dzinowanzoisa kukosha pakugadzirwa nekushandiswa kwepombi yekuisa, uye kuyedza kudzikisa zvakanyanya huwandu hwekushandiswa kwesimba, nekudaro kuderedza kusvibiswa kwezvakatipoteredza uye greenhouse effect.Indasitiri yekune dzimwe nyika yekudzivirira ine nhoroondo refu, uye zvinhu zvitsva zvekudzivirira zviri kubuda zvakare.1980 makore apfuura, China yekuvharisa pombi budiriro inononoka, iyo shoma yekumisikidza chirimwa inogona kungoburitsa nhamba shoma yepasi pevhu yakavigwa pombi yekudzivirira, asi indasitiri yeChina yekuvharisa mushure memakore makumi matatu ekuedza, kunyanya mushure memakore anoda kusvika gumi ekukura nekukurumidza, mazhinji. zvigadzirwa kubva kune chero chinhu kuva nazvo, kubva kune imwe kuenda kune diversification, mhando kubva pasi kusvika kumusoro, iyo Application iri kuramba ichiwanda.Polyurethane zvinhu parizvino ndiyo inonyanya kushandiswa insulation material munhandare yepasi rose.Rigid polyurethane ine akawanda akanakisa zvivakwa uye inoshandiswa zvakanyanya muEurope nekuUnited States mumunda wekupisa kupisa.Inenge 49% yemidziyo yekudzivirira muEurope neUnited States nedzimwe nyika dzakabudirira zvinhu zvepolyurethane, nepo muChina chikamu ichi chichiri pasi pe20%.Naizvozvo, kuchine nzvimbo yakawanda yekuvandudzwa kwe polyurethane material insulation pombi muChina.

Saka, ndakaunza kushandiswa kukuru kwechinhu chitsva che polyurethane, icho chakaita kuvandudzwa kukuru kwekushanda kwekudzivirira kwepombi yekudzivirira, uye zvakare yakaderedza zvikuru kurasikirwa kwekupisa kwepombi yekudzivirira, uye yakavandudza kushanda kwebasa reRussia.Iyo ine zvakare mabhenefiti ekuvakwa kwakapusa, mutengo wakaderera uye zvimwe zvakawanda zvakanaka, inova yakawanda yepombi inonyanya kufarirwa zvinhu.Ndinotenda kuti mushure mezvinhu zvitsva zve polyurethane zvicharamba zvichishandiswa munzvimbo itsva, zvitsva zvitsva zve polyurethane zvichagadzirwa zvakare.
