Ukusetyenziswa okuphambili kwezinto ezintsha ze-polyurethane

Kule mihla, imathiriyeli yokugquma i-polyurethane yaziwa nguye wonke umntu njengemathiriyeli yokugquma, ikakhulu esetyenziselwa ukugquma eludongeni, ukugquma kombhobho iindawo ezimbini eziphambili, ezinjengemibhobho yeoli, imibhobho yegesi kunye nokugquma eludongeni lwendlu.

Umbhobho wentsimbi yokugquma i-polyurethane ngokuchasene nokusetyenziswa kombhobho wensimbi njengomaleko okhuselayo wangaphandle, onamandla amakhulu.Akulula ukonakalisa kwaye unokumelana neempawu zomthwalo omkhulu ophezulu, ukuze ufezekise ubomi obude, umbhobho wejacket yensimbi kufuneka ube unyango oluchasene ne-corrosion.

Uyilo lwesakhiwo sokuxhasa ukuqengqeleka lunengqiqo, ukungqubana okuqengqelekayo kuncinci, amandla enkxaso esisigxina ayancitshiswa, umgaqo wohlalutyo lomatshini ulula, uzinzo lombhobho, ukhuseleko luphuculwe kakhulu.

Polyurethane insulation steel umbhobho vacuum umaleko kuphelisa ngokupheleleyo ubukho umaleko womoya conduction ubushushu kunye convection ubushushu, ukunciphisa kakhulu ilahleko ubushushu.Xa kuthelekiswa nesakhiwo se-air layer, kwi-insulation yobunzima obufanayo kunokunciphisa ubushushu bodonga lwangaphandle lwe-8-13° c.

Isixhobo se-vacuum sisombulula ngokupheleleyo ingxaki yodonga lwangaphakathi lwe-casing yentsimbi yangaphandle e-corrored lula ngumoya oshushu kunye nomanzi, ophucula kakhulu ubomi bokusebenza kombhobho womphunga ongcwatywe ngokuthe ngqo.Ubomi bemveliso bunyuswe kwiminyaka engama-30.

Umbhobho wokufakelwa kwe-polyurethaneisetyenziselwa imibhobho eyahlukeneyo yangaphakathi nangaphandle, imibhobho yokufudumeza esembindini, imibhobho yokupholisa umoya esembindini, iikhemikhali, amayeza kunye nezinye izinto zokugquma imibhobho yeshishini, iprojekthi yogcino olubandayo.Isishwankathelo se-polyurethane foam insulation pipe ukususela ekuzalweni kwezinto ezenziwe nge-polyurethane kwi-thirties, ibe njengeyona nto ibalaseleyo yokufakelwa kwe-thermal kunye nophuhliso olukhawulezayo, ukusetyenziswa kwayo kubanzi ngakumbi, ngakumbi ngenxa yolwakhiwo olulula, ukonga amandla okuthintela ukubola. kwaye isetyenziswe kwinani elikhulu lokufudumeza, ifriji, ioli, umphunga kunye nezinye iintlobo zemibhobho.Isetyenziswe ngobuninzi kwiipayipi ezahlukeneyo zokufudumeza, ukupholisa, ukuhanjiswa kweoli kunye ne-steam, njl.

Iinzuzo zezoqoqosho zokusetyenziswa kwezinto ezintsha ze-polyurethane

Umbhobho wokugqumangumba obalulekileyo ochaphazela ugcino lwamandla, uphuhliso kunye nokusetyenziswa kombhobho wokugquma uya kunikwa ingqwalasela kumazwe ehlabathi jikelele.emva kweminyaka yee-1970, amazwe angaphandle ngokubanzi afakela ukubaluleka kwimveliso kunye nokusetyenziswa kombhobho wokugquma, kwaye azame ukunciphisa ngokubonakalayo umthamo wokusetyenziswa kwamandla, ngokunciphisa ukungcoliseka kokusingqongileyo kunye nefuthe le-greenhouse.Ishishini lokugquma langaphandle linembali ende, kwaye izinto ezintsha zokugquma ziyavela.Kwiminyaka ye-1980 eyadlulayo, uphuhliso umbhobho wokufakelwa kweTshayina lucotha kakhulu, iplanti yokugquma imbalwa inokuvelisa kuphela inani elincinci lombhobho wokugquma ongaphantsi komhlaba, kodwa ishishini laseTshayina emva kweminyaka engama-30 yemizamo, ngakumbi emva kweminyaka eli-10 yophuhliso lwesantya esiphezulu, uninzi lwazo. iimveliso ukusuka nto ukuba, ukusuka enye ukuya yantlukwano, umgangatho ukusuka ezantsi ukuya phezulu, Isicelo sisiya sixhaphaka ngakumbi.Imathiriyeli yePolyurethane okwangoku iyeyona imathiriyeli yokugquma isetyenziswa kakhulu kwibala lamazwe ngamazwe.I-polyurethane eqinile ineempawu ezininzi ezibalaseleyo kwaye isetyenziswa kakhulu eYurophu nase-United States kwinkalo yokufakwa kwe-thermal.Malunga ne-49% yezinto zokugquma eYurophu nase-United States nakwamanye amazwe aphuhlileyo zizinto ze-polyurethane, ngelixa e-China le nxalenye isengaphantsi kwe-20%.Ke ngoko, kusekho indawo eninzi yokuphuhliswa kombhobho wokugquma we-polyurethane e-China.

Ngoko ke, ndazisa ukusetyenziswa okuphambili kwezinto ezintsha ze-polyurethane, eziye zaphucula kakhulu ukusebenza kwe-insulation ye-insulation pipe, kunye nokunciphisa kakhulu ukulahleka kobushushu bombhobho wokufakelwa, kunye nokuphucula ukusebenza kakuhle komsebenzi waseRashiya.Kananjalo ineengenelo zokwakha ezilula, ixabiso eliphantsi kunye nezinye iingenelo ezininzi, ibe eninzi umbhobho kakhulu izinto ozithandayo.Ndiyakholelwa ukuba emva kokuba izinto ezintsha ze-polyurethane ziya kuqhubeka zisetyenziswa kwiindawo ezintsha, izinto ezintsha ze-polyurethane nazo ziya kuveliswa.
