Ukusetshenziswa okuyinhloko kwezinto ezintsha ze-polyurethane

Kulezi zinsuku, izinto zokufakwa kwe-polyurethane yaziwa yiwo wonke umuntu njengezinto zokufakelwa, ikakhulukazi ezisetshenziselwa ukufakwa odongeni, ukufaka amapayipi izindawo ezimbili ezinkulu, njengamapayipi kawoyela, amapayipi egesi kanye nokufakwa odongeni lwendlu.

Ipayipi yensimbi yokufaka i-polyurethane ngokumelene nokusetshenziswa kwepayipi lensimbi njengesendlalelo sangaphandle sokuzivikela, esinamandla aphezulu.Akulula ukulimaza futhi ingakwazi ukumelana nezici zomthwalo omkhulu ongaphezulu, ukuze kuzuzwe impilo ende, ipayipi lejazi lensimbi lidinga ukwelashwa okulwa nokugqwala.

Idizayini yesakhiwo sokusekela esiginqikayo inengqondo, ukungqubuzana okugoqayo kuncane, amandla okusekela okugxilile ancishisiwe, isimiso sawo sokuhlaziya umshini silula, ukuzinza kwepayipi, ukuphepha kuye kwathuthukiswa kakhulu.

I-polyurethane insulation steel pipe vacuum layer iqeda ngokuphelele ukuba khona kwengqimba yomoya yokushisa nokushisa, kunciphisa kakhulu ukulahlekelwa ukushisa.Uma kuqhathaniswa nesakhiwo sesendlalelo somoya, ku-insulation ukushuba okufanayo kunganciphisa izinga lokushisa langaphandle le-8-13° c.

Isisetshenziswa se-vacuum siyixazulula ngokuphelele inkinga yodonga lwangaphakathi lwe-casing yensimbi yangaphandle olugqwala kalula umoya oshisayo nomanzi, okuthuthukisa kakhulu ukuphila kokusebenza kwepayipi lesitimu eligqitshwe ngokuqondile.Impilo yomkhiqizo yenyuswa ibe yiminyaka engama-30.

Ipayipi yokufaka i-polyurethaneisetshenziselwa amapayipi ahlukahlukene angaphakathi nangaphandle, amapayipi okufudumeza aphakathi nendawo, amapayipi okupholisa umoya amaphakathi, amakhemikhali, imithi kanye nokunye ukufakwa kwamapayipi ezimbonini, iphrojekthi yokulondoloza amakhaza.Uhlolojikelele polyurethane Foam ukwahlukanisa ipayipi kusukela kwazalwa polyurethane zokwenziwa materials in the thirties, bekulokhu kuyinto enhle kakhulu ukufakwa izinto ezishisayo ezishisayo kanye nentuthuko ngokushesha, ukusetshenziswa kwalo kuyanda kakhulu, ngenxa yokwakhiwa kwalo lula, ukonga amandla anti-ukugqwala umphumela. futhi isetshenziswa enanini elikhulu lokushisisa okuhlukahlukene, isiqandisi, uwoyela, umusi kanye nezinye izinhlobo zamapayipi.Isetshenziswa ngobuningi kumapayipi ahlukahlukene okushisa, ukupholisa, uwoyela kanye nokuhanjiswa kwesitimu, njll.

Izinzuzo zezomnotho zokusetshenziswa kwezinto ezintsha ze-polyurethane

Ipayipi le-insulationkuyisici esibalulekile esithinta ukongiwa kwamandla, ukuthuthukiswa kanye nokusetshenziswa kwepayipi lokufakwa ngaphakathi kuya ngokuya kunakwa ngamazwe emhlabeni jikelele.ngemva kweminyaka yawo-1970, amazwe angaphandle ngokuvamile anamathisela ukubaluleka ekukhiqizweni nasekusetshenzisweni kwepayipi lokufakelwa, futhi alwela ukunciphisa kakhulu inani lokusetshenziswa kwamandla, ngaleyo ndlela kuncishiswe ukungcoliswa kwemvelo kanye nomphumela we-greenhouse.Imboni yokufaka izinto zangaphandle inomlando omude, kanti nezinto ezintsha zokuhlanganisa ziyavela.Eminyakeni engu-1980 edlule, ukuthuthukiswa kwepayipi lokufakwa kwe-insulation yaseChina kuhamba kancane kakhulu, isitshalo esincane sokufakelwa singakhiqiza ipayipi elincane lokufakelwa ngaphansi komhlaba, kodwa imboni yaseShayina yokufaka i-insulation ngemva kweminyaka engama-30 yemizamo, ikakhulukazi ngemva kweminyaka engaba ngu-10 yentuthuko yesivinini esikhulu, abaningi. imikhiqizo kusuka engenalutho ukuba nayo, kusukela kokukodwa kuye kokuhlukahluka, ikhwalithi ukusuka phansi kuye phezulu, Isicelo siya ngokuya sivame kakhulu.Impahla ye-polyurethane njengamanje iyona nto esetshenziswa kakhulu ekwakhiweni komhlaba.I-polyurethane eqinile inezinto eziningi ezinhle kakhulu futhi isetshenziswa kakhulu eYurophu nase-United States emkhakheni wokufakwa kwe-thermal.Cishe u-49% wezinto zokufakelwa kwe-insulation eYurophu nase-United States nakwamanye amazwe asethuthukile ziyizinto ze-polyurethane, kuyilapho e-China lesi silinganiso singaphansi kwama-20%.Ngakho-ke, kusenendawo enkulu yokuthuthukiswa kwepayipi lokufakwa kwe-polyurethane impahla e-China.

Ngakho-ke, ngethula ukusetshenziswa okuyinhloko kwempahla entsha ye-polyurethane, eye yenza intuthuko enkulu ekusebenzeni kwe-insulation yepayipi lokufakelwa, futhi futhi yanciphisa kakhulu ukulahlekelwa ukushisa kwepayipi lokufakelwa, futhi yathuthukisa ukusebenza kahle komsebenzi waseRussia.Ibuye ibe nezinzuzo zokwakha okulula, intengo ephansi kanye nezinye izinzuzo eziningi, ibe yiphayiphi impahla ethandwa kakhulu.Ngikholelwa ukuthi ngemva kokuba izinto ezintsha ze-polyurethane zizoqhubeka zisetshenziswa ezindaweni ezintsha, kuzophinde kusungulwe izinto ezintsha ze-polyurethane.
