Kugwiritsa ntchito kwakukulu kwa zinthu zatsopano za polyurethane

Masiku ano, zinthu zotchinjiriza za polyurethane zimadziwika kwa aliyense ngati zida zotchinjiriza, zomwe zimagwiritsidwa ntchito kwambiri pakutchinjiriza pakhoma, kutsekereza chitoliro m'malo awiri akulu, monga mapaipi amafuta, mapaipi agesi ndi kutsekereza khoma lanyumba.

Polyurethane kutchinjiriza zitsulo chitoliro motsutsana ntchito zitsulo chitoliro ngati wosanjikiza kunja zoteteza, ndi mphamvu mkulu.Zosavuta kuwononga ndipo zimatha kupirira mikhalidwe ya katundu wokulirapo wapamwamba, kuti akwaniritse moyo wautali, chitoliro cha jekete lachitsulo chimayenera kukhala chotsutsana ndi dzimbiri.

Mapangidwe opangira ma rolling ndi omveka, kukangana kwapang'onopang'ono ndikochepa, mphamvu yothandizira yokhazikika imachepetsedwa, mfundo yake yowunikira makina ndi yosavuta, kukhazikika kwapaipi, chitetezo chasinthidwa kwambiri.

Polyurethane kutchinjiriza zitsulo chitoliro zingalowe wosanjikiza kwathunthu kumathetsa kukhalapo kwa mpweya wosanjikiza conduction kutentha ndi kutentha convection, kuchepetsa kwambiri imfa ya kutentha.Poyerekeza ndi mawonekedwe a mpweya wosanjikiza, makulidwe omwewo amatha kuchepetsa kutentha kwakunja kwa khoma 8-13° c.

The vacuum chipangizo kwathunthu amathetsa vuto la mkati khoma la kunja zitsulo casing mosavuta dzimbiri ndi otentha ndi yonyowa mpweya, amene kwambiri bwino ntchito moyo wa mwachindunji kukwiriridwa payipi nthunzi.Moyo wamalonda ukuwonjezeka kufika zaka 30.

Polyurethane insulation pipeamagwiritsidwa ntchito pa mapaipi osiyanasiyana m'nyumba ndi panja, mapaipi otenthetsera apakati, mapaipi apakati oziziritsa mpweya, mankhwala, mankhwala ndi zida zina zamapaipi amafuta, ntchito yoteteza kuzizira.Mwachidule polyurethane thovu kutchinjiriza chitoliro kuyambira kubadwa kwa polyurethane kupanga zipangizo mu thirties, wakhala ngati kwambiri matenthedwe kutchinjiriza zipangizo ndi chitukuko mofulumira, ntchito yake ndi zambiri ndi zambiri, chifukwa cha zomangamanga zosavuta, zopulumutsa mphamvu odana dzimbiri tingati. ndipo amagwiritsidwa ntchito mumitundu yambiri yotentha, firiji, mafuta, nthunzi ndi mapaipi amtundu wina.Amagwiritsidwa ntchito mochulukira m'mapaipi osiyanasiyana otenthetsera, kuziziritsa, kufalitsa mafuta ndi nthunzi, etc.

Ubwino wachuma pakugwiritsa ntchito zida zatsopano za polyurethane

Insulation pipendi chinthu chofunikira chomwe chikukhudza kusungidwa kwa mphamvu, chitukuko ndi kugwiritsa ntchito chitoliro cha kutchinjiriza chikukulitsidwa kwambiri ndi mayiko padziko lonse lapansi.pambuyo pa zaka za m'ma 1970, maiko akunja ambiri amangirira kufunika kwa kupanga ndi kugwiritsa ntchito chitoliro cha kutchinjiriza, ndikuyesetsa kuchepetsa kuchuluka kwa kugwiritsa ntchito mphamvu, potero kuchepetsa kuipitsidwa kwa chilengedwe ndi kutentha kwa dziko.Makampani otchinjiriza akunja ali ndi mbiri yakale, ndipo zida zatsopano zotchinjiriza zikutulukanso.Zaka 1980 zapitazo, chitukuko cha chitoliro cha China cha kutchinjiriza chitoliro ndi chodekha kwambiri, chosungirako chotchinjiriza pang'ono chimangotulutsa chitoliro chochepa chobisalira m'manda, koma mafakitale aku China atatha zaka 30 zoyesayesa, makamaka pambuyo pa zaka 10 za chitukuko chofulumira, ambiri. zopangidwa kuchokera ku chilichonse kukhala nazo, kuchokera kumodzi kupita kumitundu yosiyanasiyana, zabwino kuchokera kumunsi kupita kumtunda, Kugwiritsa ntchito kukuchulukirachulukira.Zida za polyurethane pakadali pano ndizomwe zimagwiritsidwa ntchito kwambiri pamasewera apadziko lonse lapansi.Rigid polyurethane ili ndi zinthu zambiri zabwino kwambiri ndipo imagwiritsidwa ntchito kwambiri ku Europe ndi United States pankhani ya kutchinjiriza kwamafuta.Pafupifupi 49% ya zida zotchingira ku Europe ndi United States ndi mayiko ena otukuka ndi zida za polyurethane, pomwe ku China gawoli likadali lochepera 20%.Chifukwa chake, pali malo ambiri opangira chitoliro cha polyurethane chakuthupi ku China.

Choncho, ndinayambitsa ntchito zazikulu za zipangizo zatsopano za polyurethane, zomwe zasintha kwambiri ntchito yotsekemera ya chitoliro, komanso kuchepetsa kwambiri kutentha kwa chitoliro cha chitoliro, ndikuthandizira bwino ntchito ya ku Russia.Lilinso ndi ubwino yomanga yosavuta, mtengo wotsika ndi ubwino zina zambiri, kukhala zambiri payipi ankakonda kwambiri zinthu.Ndikukhulupirira kuti pambuyo pa zipangizo zatsopano za polyurethane zidzapitiriza kugwiritsidwa ntchito m'madera atsopano, zipangizo zatsopano za polyurethane zidzapangidwanso.
