Anti corrosion kunye thermal insulation steel umbhobho umenzi
Ubushushu obuphezulu obunyulwe ngokuthe ngqo umbhobho wokugquma luhlobo lombhobho wokugquma owangcwatywa ngokuthe ngqo osebenza kakuhle, ukhuseleko nokuthembeka kunye neendleko zeprojekthi eziphantsi. Isombulula ngempumelelo iingxaki zokugqunyelelwa kwe-thermal, ukutyibilika kokutyibilika kunye nokungangeni kwamanzi kombhobho oveziweyo wesiphelo se-prefabricated wangcwatywa ngokuthe ngqo umbhobho wokugquma ubushushu bokuhambisa ubushushu obuphezulu kwi-130 ℃ - 600 ℃ kwindawo yokufudumeza umbindi wedolophu. Ubushushu obuphezulu obufakwe ngaphambili umbhobho wokugquma ongcwatywe ngokuthe ngqo awunabo ubuchwephesha obuphambili kunye nokusebenza okubonakalayo okungenakuthelekiswa nomsele wemveli kunye nombhobho ongaphezulu, kodwa ukwaneenzuzo ezimangalisayo kwezentlalo nezoqoqosho. Ikwangumlinganiselo onamandla wokufudumeza kunye nokonga amandla. Iqondo lobushushu eliphezulu prefabricated ngqo wangcwatywa umbhobho yokugquma wamkela ngokuthe ngqo ukungcwatywa umbhobho wokufudumeza ubuchwepheshe, nto leyo ephawula ukuba uphuhliso lobugcisa bombhobho wokufudumeza e-China ingene kwindawo entsha yokuqalisa.?
Umbhobho wokufakelwa kwe-thermal uqulunqwe ngumbhobho wentsimbi, i-sheath yangaphakathi ye-FRP kunye ne-sheath ye-FRP, ebonakaliswe ngokuba iquka ubushushu obuphezulu obunganyangekiyo umaleko wokufakelwa kwe-thermal, i-lubricating layer kunye ne-elastic seal. Imodeli eluncedo kusombulula ngempumelelo iingxaki zokugquma thermal, ukutyibilika ukutyibilika kunye nokungangeni kwamanzi kwesiphelo umbhobho eveziweyo prefabricated ngqo wangcwatywa umbhobho ukugquma thermal ubushushu eliphezulu ukudluliselwa ubushushu kwi-130 ℃ - 600 ℃ kwindawo zokufudumeza ezidolophini.
Ubushushu obuphezulu obufakwe ngaphambili kumbhobho wokugquma ongcwatywe ngokuthe ngqo buqulunqwe ngamalungu amane.
(1). Umbhobho wensimbi osebenzayo: ngokweemfuno zobugcisa zokuhambisa okuphakathi, umbhobho wensimbi ongenamthungo, umbhobho wentsimbi oxutywe kabini wamacala adibeneyo arc spiral welded weld wamkelwa ngokulandelanayo.
(2). umaleko we-insulation: i-polyurethane foam eqinile.
(3). Igobolondo elikhuselayo: i-polyethylene ephezulu okanye i-FRP.
(4). Umgca we-alarm wokuvuza: xa usenza i-high-temperature prefabricated ngqo engcwatyelwe umbhobho wokugquma, umgca we-alarm ungcwatywa kwi-insulation layer kufuphi nombhobho wentsimbi. Emva kokuba ukuvuza kwenzeka kwindawo ethile kumbhobho, i-alamu inganikezelwa kwisixhobo sokubona esikhethekileyo ngokuqhutywa komgca we-alamu, kwaye indawo echanekileyo kunye neqondo lokuvuza linokuboniswa, ukwenzela ukwazisa abasebenzi bokulondoloza ukujongana ne icandelo lombhobho ovuzayo ngokukhawuleza, Qinisekisa ukusebenza ngokukhuselekileyo kothungelwano lonikezelo lobushushu.
Ubushushu obuphezulu prefabricated ngqo wangcwatywa umbhobho ukugquma - iinzuzo kunye neempawu
1. Ukunciphisa iindleko zeprojekthi.
Ngokwezibalo zamasebe achaphazelekayo, umbhobho wokufudumeza umbhobho ophindwe kabini unokunciphisa ngokubanzi iindleko zeprojekthi malunga ne-25% (usebenzisa i-FRP njengoluhlu olukhuselayo) kunye ne-10% (usebenzisa i-polyethylene ephezulu njengomgangatho wokukhusela).
2. Ukulahleka kobushushu obuphantsi kunye nokonga amandla.
Umbhobho wensimbi ogqunyiweyo yinto ebalulekileyo echaphazela ukonga amandla. Uphuhliso kunye nokusetyenziswa kombhobho wensimbi ogqunyiweyo uye watsala ingqalelo ngakumbi nangakumbi kwihlabathi liphela. Emva kweminyaka yee-1970, amazwe angaphandle ngokubanzi anikele ingqalelo kwimveliso kunye nokusetyenziswa kombhobho wentsimbi wokugquma ubushushu, kwaye azame ukunciphisa kakhulu ukusetyenziswa kwamandla, ukuze kuncitshiswe ungcoliseko lokusingqongileyo kunye nefuthe le-greenhouse. Ishishini langaphandle lokugquma i-thermal linembali ende, kwaye izinto ezintsha zokufakelwa kwe-thermal zihlala zivela. Phambi ko-1980, uphuhliso lombhobho wentsimbi yokufakelwa kwe-thermal e-China lwalucotha kakhulu. Izityalo ezimbalwa zokufakelwa kwe-thermal zinokuvelisa kuphela inani elincinci lombhobho wensimbi ophantsi komhlaba ongcwatywe ngokuthe ngqo. Nangona kunjalo, emva kweminyaka engaphezu kwe-30 yemizamo, ngakumbi emva kweminyaka ephantse ibe yi-10 yophuhliso olukhawulezayo, iimveliso ezininzi ziye zasetyenziswa ngokubanzi ukusuka ekuqaleni, ukusuka kwi-single ukuya kwi-diversified, ukusuka kwi-low ukuya kumgangatho ophezulu. I-polyurethane imathiriyeli yeyona nto isetyenziswa kakhulu kwi-thermal insulation emhlabeni. I-polyurethane eqinile ineempawu ezininzi ezintle kwaye isetyenziswa ngokubanzi kwintsimi yokufakelwa kwe-thermal eYurophu naseMelika. Malunga ne-49% yezinto zokufakelwa kwe-thermal kumazwe aphuhlileyo njengeYurophu kunye ne-United States zizinto ze-polyurethane, ngelixa e-China, lo mlinganiso ungaphantsi kwe-20%. Ke ngoko, umbhobho wentsimbi ogqunyiweyo we-polyurethane usenayo indawo enkulu yophuhliso e-China.
1. Umbhobho wensimbi okhuselayo wangaphandle: khusela umgca we-insulation ukusuka ekukhukulisekeni kwamanzi aphantsi komhlaba, uxhase umbhobho osebenzayo kwaye unokuthwala umthwalo othile wangaphandle ukuqinisekisa ukusebenza okuqhelekileyo kombhobho osebenzayo.
2. I-anti corrosion coating: khusela umbhobho wentsimbi yangaphandle kwizinto ezitshabalalisayo kunye nokwandisa ubomi benkonzo yombhobho wensimbi.
3. Ukutsala umaleko wokunciphisa: qinisekisa ukuhamba ngokukhululekileyo kokwandiswa kwe-thermal kunye nokunciphisa okubandayo kombhobho wensimbi osebenzayo.
I-4, umaleko we-polyurethane we-foam: qinisekisa ubushushu bendawo ephakathi, kwaye uqinisekise ukuba umphezulu wombhobho wangaphandle ugcinwa kwiqondo lokushisa.
5. Isithintelo kunye nesibonisi: qinisekisa ukuba izinto ze-foam eziphilayo azifaki kwi-inorganic hard and high-temperature layers. Bonisa inxalenye yobushushu bomgangatho ophezulu wokumelana nobushushu.
6. Umbhobho wensimbi osebenzayo: qinisekisa ukuhamba okuqhelekileyo kwendlela yokuhambisa.
7. I-inorganic hard insulation layer: ukumelana nobushushu obuphezulu, qinisekisa ubushushu be-interface phakathi kwe-organic insulation layer kunye nokuqinisekisa ukuba i-foam ayinayo i-carbonized.
