PPU rwb thaiv tsev yog suav tias yog qhov ua tau zoo tshaj plaws niaj hnub no, vim tias cov khoom siv no muaj cov thermal conductivity qis tshaj plaws, thiab tseem muaj cov khoom siv dej tsis zoo. Cov yam ntxwv tom kawg yog vim muaj 99 feem pua ntawm cov pores kaw hauv cov khoom siv. Polyurethane ua npuas ncauj rwb thaiv tsev yog nruab nrab rau cov tshuaj, alkaline ib puag ncig thiab acid compositions. Nws belongs rau G2 chav kawm flammability thiab muaj kev tiv thaiv siab rau sab nraud influences.

Kev piav qhia dav dav

Rigid polyurethane ua npuas ncauj muaj qhov zoo tshaj plaws txuag hluav taws xob nrog cov txheej me me. Ua tsaug rau cov khoom no, nws tsim nyog rau kev daws cov haujlwm thermal rwb thaiv tsev, uas, rau kev lag luam thiab kev lag luam, xav tau kev txuag hluav taws xob zoo. Kev nqus dej ntawm cov khoom tsis pub tshaj 1.2-2.1% ntawm tag nrho cov ntim. Cov rwb thaiv tsev yog nplaim hluav taws kub txawm tias raug hluav taws ncaj qha.

PPU rwb thaiv tsev muaj qhov hnyav, uas txawv txog 60 kilograms ib cubic meter. Nws yog tus cwj pwm los ntawm lub zog zoo heev thiab kev tiv thaiv corrosion ntawm cov qauv hlau. Thaum lub sij hawm installation, tsis tas yuav tsum tau siv cov fasteners ntxiv, tsis muaj cov txuas hniav txias yog tsim nyob rau hauv tus txheej txheem. Nws muaj peev xwm cais tawm nrog kev pab los ntawm cov khoom siv no tsim ntawm txhua qhov kev teeb tsa thiab qhov loj me.

Durability

PPU rwb thaiv tsev yog qhov ruaj khov, vim qhov tseeb tias cov khoom tsis raug lwj thiab tsis daws raws li kev hloov pauv raws caij nyoog hauv cov av noo thiab kub. Nws yog tsis yooj yim sua kom tsis txhob hais txog qhov siab ntawm ib puag ncig tus phooj ywg, yog li, raws li cov qauv kev tu cev, cov khoom siv tuaj yeem siv rau hauv cov khoom txias, uas yog npaj rau khaws cov khoom noj khoom haus.

Rwb thaiv tsev yog tsim los ntawm kev siv thev naus laus zis ntawm kev nchuav polyurethane ua npuas ncauj rau hauv pwm, nrog kev pab los ntawm kev tsim cov blocks hu ua plhaub. Lawv yog siv rau kev npaj ntawm cov kav dej, kev tsim cov sandwich panels thiab slabs. Polyurethane ua npuas ncauj tuaj yeem txau rau txhua yam khoom xws li hlau, ntoo, cib, iav, thiab pob zeb. Hauv qhov no, kev teeb tsa saum npoo tsis muaj teeb meem.

Kev tsim cov PU ua npuas dej

PPU rwb thaiv tsev, kev tsim tawm uas yuav tau piav qhia hauv qab no, yog siv los tsim cov kav dej uas xav tau kev tiv thaiv tshwj xeeb. Qhov tshwm sim yog cov khoom siv thermally waterproofed, uas yog tsim raws li GOST 30732-2006. Nyob rau hauv cov ntaub ntawv no, polyurethane ua npuas ncauj yog siv raws li cov thermal rwb thaiv tsev cov ntaub ntawv, thaum tiv thaiv ya raws yog guaranteed los ntawm lub xub ntiag ntawm ib tug polyethylene txheej. Xws li cov kav dej yog npaj rau kev npaj ntawm cov cua sov mains, lub installation ntawm uas yog nqa tawm underground. Hauv cov txheej txheemHauv kev tsim cov txheej txheem peb txheej, cov hlau zoo yog siv, nrog kev pab los ntawm cov coolant yuav thauj.

Cov khoom muaj kev tiv thaiv los ntawm polyurethane ua npuas ncauj txheej, uas tshem tawm tag nrho cov cua sov. Hlau thiab polyurethane ua npuas ncauj muaj kev tiv thaiv los ntawm cov dej hauv av, uas yog ua kom ntseeg tau los ntawm qhov muaj qhov tshwj xeeb npog, uas yog ua los ntawm polyethylene. Cov kav hlau hauv polyurethane ua npuas ncauj rwb thaiv tsev tuaj yeem yog ob hom, txhua qhov cuam tshuam nrog kev siv nws tus kheej thickness ntawm rwb thaiv tsev txheej. Thawj hom yog siv rau kev teeb tsa hauv nruab nrab thaj tsam, cov xwm txheej ntawm cov xwm txheej uas muaj huab cua sov. Hom thib ob yog tsim los ua haujlwm nyob rau hauv tej yam kev mob uas tsis tshua muaj kub, hais txog cov cheeb tsam sab qaum teb. PPU-kev rwb thaiv tsev (plhaub) thaum lub sij hawm tsim khoom yog muab nrog UEC system, uas tso cai rau koj los tshawb xyuas qhov kev puas tsuaj uas tshwm sim thaum lub sijhawm ua haujlwm. Nws tso cai rau koj los tswj cov av noo ntawm txheej rwb thaiv tsev, taw qhia thaum qib nce.

FPU nqi

PPU rwb thaiv tsev, tus nqi ntawm cov lus qhia hauv qab no, tuaj yeem yog tib txoj kev daws teeb meem yog tias koj xav tau cov kav dej thaiv. Yog li, yog tias koj xav tau cov txheej txheem ntxiv, tom qab ntawd nrog cov yeeb nkab txoj kab uas hla ntawm 507 millimeters, phab ntsa thickness ntawm 3.5 millimeters thiab lub plhaub taub ntawm 125 millimeters, tus nqi ntawm rwb thaiv tsev yam tsis muaj steel yeeb nkab ib kab meter yuav yog 376 rubles. Nrog rau qhov nce ntawm cov kev txwv saum toj no rau 89x3, 5x160 millimeters, tus nqi nce mus rau 552 rubles. Qhov loj me, sib npaug ntawm 630x8x800, hais txog tus nqi ntawm 8600 rubles.

zoo sab ntawm PU-insulated kav

Yog tias koj txiav txim siab insulate cov kav dej siv polyurethane ua npuas ncauj, koj tuaj yeem suav nrog cov yam ntxwv ntawm cov khoom siv high-tech. Ntawm lawv, ib qho tuaj yeem tawm qhov tsis tseem ceeb ntawm cov thermal conductivity, uas yog 0.027 W / mk. Tsis hais txog lub zog, nrog rau kev tiv thaiv corrosion. PPU yuav tiv thaiv cov yeeb nkab steel zoo dua li armored pob zeb lossis bitumen perlite. Cov hlau nto tsis tas yuav tsum tau kho nrog cov txheej txheem tiv thaiv corrosion, uas yuav ua rau muaj kev kub ntxhov ntau dua li cov ntxhia wool rwb thaiv tsev. Tom qab ua haujlwm li no, cov kav dej yuav tuaj yeem ua haujlwm rau 25 xyoo lossis ntau dua. Qhov no yog ob peb zaug ntev dua li lub sijhawm uas tau muab rau cov kav dej tsis muaj kev tsim nyog. Nyob rau hauv lub xub ntiag ntawm UEC system, koj yuav muaj peev xwm tswj kev ncaj ncees ntawm cov khoom thaum lub sij hawm ua hauj lwm, tshem tawm excavation. Nws yog tsim nyog hais txog qhov zoo ntawm kev lag luam, uas tau qhia nyob rau hauv qhov tseeb hais tias kev siv cov kav dej nrog polyurethane ua npuas ncauj rwb thaiv tsev yuav txo tau lub sij hawm installation ntawm cua sov tes hauj lwm los ntawm peb lub sij hawm, txo nqi txij nkawm los ntawm 9 lub sij hawm, tab sis raws li kev kho cov hauj lwm, lawv yuav ua tau. 3 zaug pheej yig dua.

Zaj lus

Yog tias koj siv cov kav dej ua ntej insulated raws li tau piav qhia saum toj no, koj tuaj yeem txo tus nqi ntawm kev tsim kho thiab kev ua haujlwm tom ntej. Koj yuav muaj lub cib fimtxo qis qhov poob ntawm cov cua sov, uas thaum siv cov kav dej zoo li no yog 2%. Cov khoom hauv polyurethane ua npuas ncauj rwb thaiv tsev tuaj yeem ua haujlwm ntawm qhov ntsuas kub zoo, uas txawv ntawm -80 txog +130 degrees, uas yog qhov tsim nyog rau qee thaj tsam ntawm Russia.
