Anti dzimbiri ndi matenthedwe kutchinjiriza zitsulo chitoliro wopanga
Kutentha kwakukulu komwe kumayikidwa mwachindunji kukwiriridwa kutchinjiriza chitoliro ndi mtundu wa chitoliro chokhazikika chokhazikika chokhazikika ndi ntchito yabwino yotchinjiriza, chitetezo ndi kudalirika komanso mtengo wotsika wa polojekiti. Iwo bwino amathetsa mavuto kutchinjiriza matenthedwe, kutsetsereka kondomu ndi madzi a poyera chitoliro mapeto a prefabricated mwachindunji m'manda matenthedwe kutchinjiriza chitoliro kwa kufala kutentha kutentha pa 130 ℃ - 600 ℃ mu Kutentha chapakati m'tawuni. High kutentha prefabricated mwachindunji kukwiriridwa kutchinjiriza chitoliro osati ali luso patsogolo ndi ntchito zothandiza n'zosayerekezeka ndi ngalande miyambo ndi pamwamba payipi, komanso ali ndi ubwino wochititsa chidwi chikhalidwe ndi zachuma. Ndichiyeso champhamvu cha kutentha ndi kupulumutsa mphamvu. High kutentha prefabricated mwachindunji m'manda kutchinjiriza chitoliro utenga mwachindunji kukwiriridwa Kutentha payipi luso, zomwe zimasonyeza kuti chitukuko cha Kutentha payipi luso China walowa poyambira.?
Chitoliro chotenthetsera chotenthetsera chimapangidwa ndi chitoliro chachitsulo, chipolopolo chamkati cha FRP ndi chipolopolo cha FRP, chomwe chimadziwika chifukwa chimaphatikizansopo kusanjikiza kotentha kwambiri kwamafuta, kusanjikiza kopaka mafuta ndi chisindikizo chotanuka. Utility chitsanzo bwino amathetsa mavuto a kutchinjiriza matenthedwe, kutsetsereka kondomu ndi madzi a poyera chitoliro mapeto a prefabricated mwachindunji m'manda matenthedwe kutchinjiriza chitoliro kwa kufala kutentha kutentha pa 130 ℃ - 600 ℃ mu Kutentha chapakati m'tawuni.
Mkulu kutentha prefabricated mwachindunji m'manda kutchinjiriza chitoliro makamaka wapangidwa mbali zinayi.
(1). Chitoliro chachitsulo chogwira ntchito: molingana ndi zofunikira zaumisiri zotumizira sing'anga, chitoliro chopanda chitsulo chosapanga dzimbiri, chitoliro chazitsulo ziwiri zokhala ndi mbali ziwiri zokhala ndi mipiringidzo yachitsulo chimatengedwa motsatana.
(2). Insulation layer: thovu lolimba la polyurethane.
(3). Chipolopolo choteteza: polyethylene yochuluka kwambiri kapena FRP.
(4). Kutayikira Alamu mzere: pamene kupanga mkulu-kutentha prefabricated mwachindunji kukwiriridwa kutchinjiriza chitoliro, ndi alamu mzere m'manda mu insulation wosanjikiza pafupi ndi chitoliro zitsulo. Kamodzi kutayikira kumachitika kwinakwake mu chitoliro, alamu ikhoza kuperekedwa pa chida chapadera chodziwikiratu kudzera pakuwongolera mzere wa alamu, ndipo malo olondola ndi kuchuluka kwa kutayikira kumatha kuwonetsedwa, kuti adziwitse ogwira ntchito yosamalira kuti athane ndi kutayikira chitoliro gawo mwamsanga, Kuonetsetsa ntchito otetezeka maukonde kutentha kotunga.
Mkulu kutentha prefabricated mwachindunji m'manda kutchinjiriza chitoliro - ubwino ndi makhalidwe
1. Kuchepetsa mtengo wa ntchito.
Malinga ndi mawerengedwe a m'madipatimenti oyenerera, mapaipi awiri otenthetsera mapaipi amatha kuchepetsa mtengo wa polojekitiyo ndi pafupifupi 25% (pogwiritsa ntchito FRP ngati wosanjikiza woteteza) ndi 10% (pogwiritsa ntchito polyethylene yolimba kwambiri ngati gawo loteteza).
2. Kutaya kutentha kochepa komanso kupulumutsa mphamvu.
Chitoliro chachitsulo chosakanizidwa ndi chinthu chofunikira chomwe chimakhudza kupulumutsa mphamvu. Kukula ndi kugwiritsa ntchito chitoliro chachitsulo chopangidwa ndi insulated chakopa chidwi kwambiri padziko lonse lapansi. Pambuyo pa zaka za m'ma 1970, mayiko akunja ambiri kulabadira kupanga ndi ntchito matenthedwe kutchinjiriza zitsulo chitoliro, ndi kuyesetsa kwambiri kuchepetsa mowa mphamvu, kuti kuchepetsa kuipitsidwa kwa chilengedwe ndi wowonjezera kutentha kwenikweni. Makampani otchinjiriza akunja akunja ali ndi mbiri yakale, ndipo zida zatsopano zotchinjiriza zotentha zimatuluka nthawi zonse. Isanafike 1980, chitukuko cha matenthedwe kutchinjiriza zitsulo chitoliro ku China anali pang'onopang'ono. A ochepa matenthedwe kutchinjiriza zomera kokha kutulutsa pang'ono mobisa mwachindunji m'manda matenthedwe kutchinjiriza zitsulo chitoliro. Komabe, patatha zaka zoposa 30 zoyesayesa, makamaka pambuyo pa zaka pafupifupi 10 zachitukuko chofulumira, zinthu zambiri zakhala zikugwiritsidwa ntchito mowonjezereka kuyambira pachiyambi, kuchokera kumodzi kupita ku zosiyana, kuchokera kutsika mpaka kupamwamba. Polyurethane ndi chinthu chomwe chimagwiritsidwa ntchito kwambiri padziko lonse lapansi. Olimba polyurethane ali katundu zabwino kwambiri ndipo chimagwiritsidwa ntchito m'munda wa kutchinjiriza matenthedwe ku Ulaya ndi America. Pafupifupi 49% yazinthu zotchinjiriza zamafuta m'maiko otukuka monga Europe ndi United States ndi zida za polyurethane, pomwe ku China, gawo ili ndi lochepera 20%. Choncho, polyurethane insulated zitsulo chitoliro akadali lalikulu danga chitukuko mu China.
1. Chitoliro chachitsulo choteteza kunja: kuteteza wosanjikiza wosanjikiza ku kukokoloka kwa madzi apansi, kuthandizira chitoliro chogwira ntchito ndipo chikhoza kunyamula katundu wina wakunja kuonetsetsa kuti chitoliro chikugwira ntchito bwino.
2. Anti-corrosion №: kuteteza chitoliro chakunja chachitsulo kuzinthu zowonongeka ndikutalikitsa moyo wautumiki wa chitoliro chachitsulo.
3. Kokani wosanjikiza wochepetsera: onetsetsani kuyenda kwaulere kwa kufalikira kwamafuta ndi kuzizira kozizira kwa chitoliro chachitsulo chogwira ntchito.
4, polyurethane thovu wosanjikiza: onetsetsani kutentha kwa sing'anga, ndi kuonetsetsa kuti pamwamba chubu akunja amasungidwa firiji.
5. Chotchinga ndi chowunikira: onetsetsani kuti organic thovu sichilowa mu organic hard and high-temperature kugonjetsedwa. Onetsani mbali ya kutentha kwa wosanjikiza wotentha kwambiri.
6. Ntchito zitsulo chitoliro: kuonetsetsa otaya yachibadwa ya sing'anga kunyamula.
7. Inorganic hard insulation layer: kutentha kwambiri kukana, kuonetsetsa kutentha kwa mawonekedwe pakati pa organic insulation wosanjikiza ndikuwonetsetsa kuti chithovucho sichikhala ndi mpweya.
