Cov khoom siv rwb thaiv tsev yog nruj polyurethane ua npuas ncauj nrog qhov ceev ntawm 60kg / m3 txog 80kg / m3, uas ua tiav qhov sib txawv ntawm cov yeeb nkab steel thiab cov casing, thiab muaj qee qhov kev sib txuas ua ke los ua qhov chaw nruab nrab ntawm cov yeeb nkab steel, txheej casing. thiab rwb thaiv tsev txheej tsim ib qho khoom tag nrho. Polyurethane ncaj-faus rwb thaiv tsev yeeb nkab ua npuas ncauj muaj cov khoom siv zoo thiab thermal rwb thaiv tsev. Nws tuaj yeem tiv taus qhov kub ntawm 120 degree thiab tuaj yeem tiv taus qhov kub ntawm 180 degree los ntawm kev hloov kho lossis ua ke nrog lwm cov ntaub ntawv rwb thaiv tsev.
1. Anti-corrosion txheej: tiv thaiv cov yeeb nkab steel sab nraud kom tsis txhob xeb ntawm cov yeeb nkab steel thiab ua rau lub neej ntev ntawm cov yeeb nkab steel. cov
2. Kev tiv thaiv sab nrauv steel yeeb nkab: tiv thaiv cov txheej txheem rwb thaiv tsev los ntawm kev yaig hauv av, txhawb nqa cov yeeb nkab ua haujlwm thiab tuaj yeem tiv taus qee yam khoom siv sab nraud, ua kom muaj kev ua haujlwm zoo ntawm cov yeeb nkab ua haujlwm. cov
3. Polyurethane ua npuas ncauj txheej: ua kom qhov kub thiab txias ntawm qhov nruab nrab thiab xyuas kom meej tias qhov chaw ntawm lub raj tiv thaiv sab nrauv tseem nyob ntawm qhov kub thiab txias. cov
4. Barrier thiab reflective txheej: xyuas kom meej tias cov ntaub ntawv organic ua npuas ncauj tsis nkag mus rau inorganic hard-temperature resistant txheej; qhia txog ib feem ntawm cov cua sov ntawm cov txheej txheem kub-resistant. cov
5. Inorganic nyuaj rwb thaiv tsev txheej: kub tsis kam, kom ntseeg tau lub interface kub nrog cov organic rwb thaiv tsev txheej, thiab xyuas kom meej tias cov npuas dej tsis carbonized.
6. Drag txo txheej: ua kom lub zog dawb ntawm cov yeeb nkab ua haujlwm vim thermal expansion thiab contraction. cov
7. Ua hauj lwm steel yeeb nkab: xyuas kom lub cev ntws ntawm qhov nruab nrab conveying.
Cov yeeb nkab faus ncaj qha muaj cov yam ntxwv zoo xws li kev rwb thaiv tsev zoo, tsis muaj dej, tiv thaiv corrosion, rwb thaiv tsev kub, suab rwb thaiv tsev, nplaim hluav taws kub, txias tsis kam, tiv thaiv corrosion, lub teeb muaj peev xwm, siab zog, yooj yim thiab ceev kev tsim kho, thiab tsis ntshai ntawm cog cag pos. Lawv tau dhau los ua kev xaiv nrov hauv kev tsim kho, kev thauj mus los, roj av, thiab kev lag luam tshuaj lom neeg. Nws yog ib qho khoom siv tsis tseem ceeb rau kev rwb thaiv tsev thermal, waterproofing, sealing thiab lwm yam kev lag luam xws li hluav taws xob fais fab thiab tub yees. Ncaj nraim faus thermal rwb thaiv tsev kav yog siv nyob rau hauv ntau yam sab hauv tsev thiab sab nraum zoov pipelines, central cua kub pipelines, central cua txias pipelines, tshuaj kev lag luam, thiab lwm yam industrial pipelines rau thermal rwb thaiv tsev thiab txias rwb thaiv tsev tej yaam num, roj pipeline tej yaam num, chav kis tau tus mob thiab lwm yam pipeline tej yaam num. Cov kav dej faus ncaj qha tuaj yeem muab faus ncaj qha rau hauv 0.6-1.2 meters ntawm cov av khov, thiab cov cua sov tuaj yeem txo tau ntau dua 40% dua li cov kav dej zoo tib yam. Lub neej ua haujlwm yog ntau dua 3-5 lub sij hawm ntev dua li lwm cov thermal rwb thaiv tsev thiab cov khoom siv tiv thaiv corrosion, thiab lub neej kev pabcuam tuaj yeem ncav cuag 30-50 xyoo.
