Cov nyhuv ntawm anticorrosion thiab rwb thaiv tsev ntawm cov yeeb nkab rwb thaiv tsev

Thermal rwb thaiv tsev yeeb nkab haum rau ntau yam xov xwm nyob rau hauv qhov ntau ntawm -50 degree C-150 degree C. Nws yog dav siv nyob rau hauv lub xub ntiag ntawm central cua sov, txias thiab thermal tsheb thauj mus los, txias cia, thee mines , roj av, tshuaj thiab lwm yam lag luam Essence

Cov yeeb nkab rwb thaiv tsev yog nruj nreem khi rau cov tawv nqaij ntawm cov yeeb nkab steel vim hais tias cov polyurethane nyuaj ua npuas ncauj sov txheej yog cais los ntawm infiltration ntawm huab cua thiab dej, uas muaj peev xwm ua si ib tug zoo anti-corrosion nyhuv. High-density polyethylene shells thiab iav fiber reinforcement shells muaj zoo tiv thaiv corrosion, rwb thaiv tsev thiab txhua yam kev ua haujlwm. Nyob rau tib lub sijhawm, nws cov npuas dej raug kaw, thiab qhov nqus dej me me. Yog li ntawd, nws yog ib qho nyuaj rau corrode sab nraum cua thiab dej.

Lub neej kev pab cuam ntawm cov yeeb nkab thermal rwb thaiv tsev tuaj yeem ncav cuag ntau dua 50 xyoo, uas yog 3 mus rau 4 npaug siab dua li cov qauv ditch layout thiab kev teeb tsa ntawm kev tawm tsam. Nws yog qis dua li lwm cov khoom siv thermal rwb thaiv tsev cov kav dej, thiab cov nyhuv thermal rwb thaiv tsev tau zoo dua 4-9 zaug. Nws muaj qhov nqus dej tsawg, txog 0.2kg / m2. Yog vim li cas rau qhov tsis tshua muaj dej nqus yog tias qhov kaw cuffs ntawm polyurethane ua npuas ncauj yog li 92%.

Cov yeeb nkab rwb thaiv tsev tsis tas yuav tsum muaj lub trench loj. Nws tsuas yog yuav tsum tau faus cov yeeb nkab rwb thaiv tsev hauv av, yog li nws txo qis kev ua haujlwm ntawm qhov project, txo cov av qeeg excavation li ntawm 50%, thiab txo cov pej xeem masonry thiab pob zeb los ntawm 90%. Nyob rau tib lub sij hawm, cov thermal rwb thaiv tsev yeeb nkab ua thiab cov kwj deg ntawm qhov chaw yog ua tib yam. Ntev npaum li qhov kev sib txuas ntawm qhov chaw yuav tsum tau ua, nws tuaj yeem txo qis txog 50% ntawm lub sijhawm tsim kho.

Nws yog qis dua li lwm cov khoom siv thermal rwb thaiv tsev, thiab cov thermal rwb thaiv tsev cov nyhuv yog nce los ntawm 4 mus rau 9 zaug. Muaj qhov nqus dej tsawg, txog 0.2kg/m2. Yog vim li cas rau qhov tsis tshua muaj dej nqus yog tias qhov kaw ntawm polyurethane ua npuas ncauj yog li 92%. Tsawg thermal cua sov coefficient thiab tsis tshua muaj dej nqus tus nqi, ua ke nrog high-density polyethylene los yog iav fiber reinforcement shells nrog zoo thermal rwb thaiv tsev thiab waterproof kev ua tau zoo, uas hloov qhov teeb meem ntawm "hnav ib tug ntub paj rwb tsho" rau cov tsoos av groove cua sov yeeb nkab, uas. txo cov cua sov ua kom zoo heev Cov thermal poob tag nrho, qhov kub ntawm cov cua sov poob yog 2%, tsawg dua 10% ntawm cov txheej txheem thoob ntiaj teb.

Anti-corrosion thiab rwb thaiv tsev kev ua tau zoo, kev pab lub neej ntev.

Vim hais tias cov polyurethane nyuaj ua npuas ncauj rwb thaiv tsev txheej yog nruj me ntsis sib koom ua ke ntawm cov yeeb nkab steel txheej txheej ntawm daim tawv nqaij, uas cais cov infiltration ntawm huab cua thiab dej, nws muaj peev xwm ua si ib tug zoo anti-corrosion nyhuv. Nyob rau tib lub sijhawm, nws cov npuas dej raug kaw, thiab qhov nqus dej me me. High-density polyethylene shells thiab iav fiber reinforcement shells muaj zoo tiv thaiv corrosion, rwb thaiv tsev thiab txhua yam khoom. Yog li ntawd, cov tawv nqaij sab nrauv ntawm cov yeeb nkab steel ua haujlwm yog qhov nyuaj rau erode nrog cov cua sab nraud thiab dej. Raws li ntev raws li cov dej zoo hauv cov raj xa dej tau kho tau zoo, raws li cov ntaub ntawv txawv teb chaws, kev pab cuam lub neej ntawm high-temperature prefabricated rwb thaiv tsev yeeb nkab tuaj yeem ncav cuag ntau tshaj 50 xyoo, uas yog 3 mus rau 4 npaug siab dua li cov qauv ditch layout thiab overhead. daim ntawv lo.
