Iyo yakananga yakavigwa yekuvharisa pombi inopupuma nemakemikari maitiro e-high-function polyether polyol composite zvinhu uye polymethyl polyphenyl polyisocyanate seyakagadzirwa.Mapombi akanyatsovigwa anopisa anopisa anoshandiswa pakupisa uye kutonhora kwekudzivirira mapurojekiti epombi dzakasiyana-siyana dzemukati nekunze, pombi dzepakati dzekudziya, pombi dzepakati pemhepo yekupisa, makemikari, mishonga uye mamwe mapombi emaindasitiri.Kubva pakuzvarwa kwe polyurethane composite zvinhu muma 1930s, pombi ye polyurethane foam insulation yakagadziridzwa nekukurumidza sechinhu chakanakisa chekudzivirira kupisa kwemafuta, uye huwandu hwekushandisa hwayo hwawedzera kuwedzera.Inoshandiswa zvakanyanya mumapaipi akasiyana-siyana sekudziya, kutonhora, kutakura mafuta, uye kufambisa kwemhepo.

Matambudziko akajairika uye zvigadziriso pakuvaka zvakananga kuvigwa kupisa kwepombi dzekudzivirira

Ichi chiitiko chinowanzoitika mumatsutso nechando kana mukuvaka kwemangwanani, nekuti tembiricha inodonha kamwe kamwe kana tembiricha yakadzikira.Inogona kugadziriswa nekuwedzera ambient tembiricha uye tembiricha yezvinhu zvitema.Kazhinji, tembiricha yezvinhu zvitema inosimudzwa kusvika 30-60 ° C, uye tembiricha yepakati inosimudzwa kusvika 20-30 ° C.

Chiitiko ichi chinowanzoitika muchirimo nechirimo kana panguva yekuvaka masikati, nekuti tembiricha inongoerekana yakwira uye tembiricha yakanyanya.Zvinhu zvitema zvinogona kutonhodzwa nemvura inotonhora kana kuiswa panze usiku kuitira kutonhora kwepanyama kudzivirira zuva rakananga.

Kusimba kwefuro kwepombi yakavigwa yakananga idiki uye furo rakapfava.Ichi chiitiko chinokonzerwa nekusaenzana kwehuwandu hwezvinhu zvitema uye zvichena.Kuwanda kwezvinhu zvitema zvinogona kuwedzerwa zvakakodzera (1: 1-1.05).Chenjerera kuti urege kuita chikamu chezvinhu zvitema zvakanyanya, kana zvisina kudaro, zvichakonzera Iyo furo inova brittle, iyo inokanganisawo kushanda kwefuro.

Yakananga yakavigwa insulation pombi yave ine ruzivo rwepamusoro mune dzimwe nyika dzakabudirira kunze kwenyika.Mumakore gumi apfuura, mainjiniya ekudziya emunyika yangu uye vashandi vehunyanzvi vari kusimudzira kuvandudzwa kwepombi network yekuisa tekinoroji kusvika padanho repamusoro nekugaya uye kutora iyi tekinoroji yepamusoro.Mhedzisiro inoshanda mumakore gumi apfuura yakaratidza zvizere kuti nzira yekuradzika yekuvigwa yakananga yekuvharisa pombi ine mabhenefiti akawanda kana ichienzaniswa neyechinyakare mugero uye nekuisa pamusoro.Iyo yakananga-yakavigwa yemafuta ekudzivirira pombi inosanganisirwa zvakanyanya nepombi yesimbi yekufambisa iyo yepakati, yakakwirira-density polyethylene yekunze casing, uye yakasimba polyurethane furo insulation layer pakati pepombi yesimbi uye yekunze casing.Iri zvakare ndiro simba remukati rekufambisa kwekukurumidza kusimudzira kwepolyurethane thermal insulation yakananga mapaipi akavigwa muinjiniya yekudziya yenyika yangu.
