Rwb thaiv tsev loj inch kauv yeeb nkab yam ntxwv:
Polyurethane ua npuas ncauj muaj cov khoom zoo thiab cov khoom siv thermal rwb thaiv tsev, feem ntau tuaj yeem tiv taus qhov kub thiab txias 120 degree, los ntawm kev hloov kho lossis ua ke nrog lwm cov ntaub ntawv thermal rwb thaiv tsev tuaj yeem tiv taus qhov kub ntawm 180 degree.
Polyurethane faus rwb thaiv tsev yeeb nkab rwb thaiv tsev kev ua tau zoo, tuaj yeem ua kom ntseeg tau tias qhov kub ntawm cov khoom siv thauj mus los sab hauv tsis raug hloov pauv, nyob rau lub caij ntuj no txias ua haujlwm zoo. Polyurethane faus thermal rwb thaiv tsev yeeb nkab suab rwb thaiv tsev kev ua tau zoo heev, kom tsis txhob muaj kev thauj mus los ntawm cov kua hauv cov kav dej ntws los ntawm lub suab nrov. Nyob rau tib lub sij hawm polyurethane faus rwb thaiv tsev yeeb nkab tuaj yeem tiv thaiv corrosion, thiab tsis nqus dej, ua rau cov yeeb nkab installation qhov chaw tsis txwv, tuaj yeem siv rau ntau qhov chaw. Polyurethane faus rwb thaiv tsev yeeb nkab tsim yog yooj yim thiab ceev, high efficiency, txo cov nqi peev. Polyurethane faus thermal rwb thaiv tsev yeeb nkab kom tsis muaj cua sov, tuaj yeem txuag hluav taws xob.
Raws li cov tuam haujlwm tseem ceeb ntawm kev suav, ob chav tswj cua sov yeeb nkab, feem ntau, tuaj yeem txo qhov project nqi ntawm 25% (siv cov iav fiber reinforced yas los ua cov txheej txheem tiv thaiv) thiab 10% (siv cov polyethylene high-density los ua kev tiv thaiv. txheej) los yog li ntawd.
Polyurethane faus cua sov preservation yeeb nkab nws cov thermal conductivity: λ {{{0}}}.013-0.03kcal/m?h?oC, dua li lwm yam uas feem ntau siv nyob rau yav dhau los cov yeeb nkab rwb thaiv tsev cov khoom yog qis dua cov cua sov. preservation nyhuv los txhim kho lub tshav kub preservation nyhuv ntawm 4 ~ 9 zaug. Thiab tom qab ntawd nws cov dej nqus dej tsawg heev, txog 0.2kg / m2. Qhov laj thawj rau kev nqus dej tsawg yog vim qhov kaw ntawm tes ntawm polyurethane ua npuas ncauj yog siab li 92% los yog li ntawd. Tsawg thermal conductivity thiab tsis tshua muaj dej nqus, ua ke nrog cov txheej txheem rwb thaiv tsev thiab sab nraum cov dej tsis zoo ntawm cov polyethylene los yog iav fiber reinforced yas tiv thaiv plhaub, hloov cov tsoos trench tso cua sov pipeline "hnav lub tsho ntub dej", zoo heev txo qhov zuag qhia tag nrho. Thaum tshav kub kub poob ntawm cov kav dej cua sov, cua sov poob ntawm cov cua sov network ntawm 2%, tsawg dua 10% ntawm cov txheej txheem thoob ntiaj teb.
