Polyurethane ua npuas ncauj boards tau ntse siv niaj hnub no rau thermal rwb thaiv tsev ntawm lub ru tsev, pem teb, qab nthab ntawm lub tsev, sab hauv thiab sab nrauv phab ntsa ntawm lub tsev. Kev siv cov vaj huam sib luag no tuaj yeem txo qhov tuab ntawm cov phab ntsa tau tsim. Qhov no txo tus nqi ntawm kev yuav cov khoom siv hauv tsev kim, thiab tseem txo cov nqi cua sov.
yam ntxwv ntawm polyurethane ua npuas ncauj boards
Cov panels muaj cov yam ntxwv zoo, lawv cov thermal conductivity coefficient yog 0.019-0.028 W / mK. Nws siab npaum li cov pob zeb thiab cib (kwv yees li 10 npaug).
Polyurethane ua npuas ncauj rwb thaiv tsev hauv cov laug cam tsis ntshai ntawm qhov kub thiab txias, koj tuaj yeem ua haujlwm nrog nws hauv txhua qhov huab cua. Hauv qhov no nws txawv ntawm cov kua polyurethane ua npuas ncauj, uas yog txau los ntawm lub tog raj kheej.
Polyurethane ua npuas ncauj slabs yog lub teeb yuag, uas txo cov load ntawm lub hauv paus thaum siv qhov nokhoom.
Slabs yog tsim los ntawm cov tawv polyurethane ua npuas ncauj nrog cov qauv kaw. Lawv yog cov yooj yim thiab them nrog kraft ntawv, fiberglass ntaub, ntawv ci, armofol. Cov txheej txheej (ib sab thiab ob sab) ua kom lub zog ntawm cov vaj huam sib luag, tiv thaiv lawv los ntawm hluav taws xob ultraviolet.
Polyurethane ua npuas ncauj boards muaj ib tug du nto, yog li tag nrho nto sheathed nrog no insulator yuav tiaj tus. Lawv tuaj yeem siv tsis tau tsuas yog rau rwb thaiv tsev, tab sis kuj thaum txhim kho underfloor cua sov, thiab kuj yog lub hauv paus rau plaster.
Ntau yam khoom
Muaj peb hom polyurethane ua npuas ncauj:
- Qhib cell. Cov qauv ntawm cov khoom muaj xws li interconnected qhib hlwb. Hom polyurethane ua npuas ncauj no muaj qhov zoo tshaj plaws kev txuag hluav taws xob. Tsis tas li ntawd, qhov rwb thaiv tsev no absorbs cov dej noo ntau dhau, thiab thaum nws poob qis hauv qhov muaj pes tsawg leeg ntawm huab cua, nws muab nws tawm. Nyob rau hauv ib chav tsev uas cov phab ntsa yog them nrog cov khoom no, nws tsis heev ntub los yog, conversely, qhuav. Lub peev xwm los nqus dej sai sai yog qhov zoo thiab qhov tsis zoo (qee zaum). Yog tias muaj dej noo ntau dhau, thiab huab cua kub poob qis dua xoom, cov rwb thaiv tsev ntub dej pib khov thiab tawg. Yog li ntawd, qhib-cell polyurethane ua npuas ncauj tsuas yog siv los npog qhov chaw sab hauv tsev, qhov kub tsis poob mus rau xoom. Hom polyurethane ua npuas ncauj no yog pheej yig.
- Closed cell. Cov khoom siv kuj muaj cov hlwb, tab sis lawv raug cais tawm ntawm ib leeg. Cov cuab yeej no tsis tso cai rau nws nqus dej noo,Yog li ntawd, nws yog siv rau kev ua haujlwm sab nraum zoov. Tab sis nws yog qhov zoo no uas yog qhov zoo dua yog tias nws tsim nyog rau insulate lub tsev los ntawm sab nraud. Cov khoom tuaj yeem tiv tsis tau tsuas yog noo noo, tab sis txawm los nag thiab daus. Qhov tsis zoo ntawm cov khoom yog tus nqi siab.
- Nplooj. Cov khoom pheej yig nrog kev txuag hluav taws xob zoo. Nws yog siv feem ntau rau kev ua haujlwm sab hauv. Yog tias cov phab ntsa sab nraud yog insulated nrog cov phiaj no, ces nws yog ib qho tsim nyog yuav tsum tau cais lawv los ntawm cov dej noo ntxiv. Lub thickness ntawm daim hlau tuaj yeem yog los ntawm 2 mus rau 10 centimeters, lawv tuaj yeem ntsia ntawm nws tus kheej. Kev teeb tsa ntawm daim hlau tsis siv sijhawm ntau thiab tsis tas yuav siv cov cuab yeej tshwj xeeb. Kev pab cuam lub neej ntawm cov rwb thaiv tsev yog txog 20 xyoo.
txiaj ntsig
Qhov nrov ntawm polyurethane ua npuas ncauj boards rau rwb thaiv tsev yog nkag siab. Cov khoom siv muaj tus nqi siab ntawm lub suab rwb thaiv tsev thiab thermal rwb thaiv tsev. Cov khoom siv dej tsis sib xws tso cai rau polyurethane ua npuas ncauj tiv thaiv rotting, fungus tsim, thiab kub hloov pauv loj. Cov khoom siv tsis ua rau muaj kev tsis haum, uas tseem ceeb heev thaum siv nws hauv thaj chaw nyob.
Lub teeb yuag ntawm polyurethane ua npuas ncauj tsis ua rau thauj khoom ntawm tus ncej ntawm tag nrho cov qauv. Cov khoom siv tuaj yeem ua tau raws li qhov xav tau, cov cuab yeej no tso cai rau nws siv rau kev tsim cov txaj, rooj tog zaum.
Polyurethane ua npuas ncauj boards yooj yim rau nruab thiab txheej txheem, lawv yooj yim txiav, laum, saw. Durable, khaws lawv cov thermal rwb thaiv tsev yam tsis muaj kev poob zoo mus txog tsib caug xyoo. Lawv tuaj yeem rhuav tshem thiab siv lwm qhov.
Flaws
Polyurethane ua npuas ncauj tuaj yeem tawg thaum raug ultraviolet teeb. Txhawm rau tiv thaiv lub hnub ci, koj tuaj yeem pleev xim lossis siv plaster.
Lwm qhov tsis zoo ntawm cov khoom yog tias nws ua kom sov sai sai. Kub kub yuav tsis ua rau nws ignite, tab sis cov khoom yuav pib smolder. Hauv cov chaw uas qhov chaw tuaj yeem ua kom sov, nws yog qhov zoo dua los siv cov rwb thaiv tsev sib txawv.
Txhim kho cov cua sov insulator
Feem ntau, PPU panels insulate cov phab ntsa sab hauv thiab sab nraud ntawm cov tsev. Nws yog qhov yooj yim los siv ua npuas ncauj nrog qhov loj ntawm 600 × 1200.
Ua ntej, qhov chaw yog ntxuav ntawm av thiab hmoov av, ces tag nrho cov kab nrib pleb yog them nrog cement mortar thiab primed. Cov phiaj yog tsau rau ntawm phab ntsa nrog cov kua nplaum tshwj xeeb lossis bituminous mastic.
Txhawm rau tiv thaiv lub tsev tsev nrog polyurethane ua npuas ncauj boards (ua npuas ncauj yog nws cov analogue, tab sis feem ntau yog siv rau kev ua haujlwm sab nraum zoov), cov yas dowels yog siv. Nyob rau hauv thiaj li yuav kom cov paib nyob tiaj tus ntawm qhov chaw, lawv raug nias rau ntawm phab ntsa, qhov tseeb installation yog xyuas, thiab ces los ntawm lub qhov yog ua nrog ib tug puncher. Kev saib xyuas yuav tsum tau ua kom paub tseeb tias qhov kev xyaum hla dhau ntawm cov nplais rau hauv phab ntsa.
Qhov yuav tsum tau ua rau hauv nruab nrab thiab raws cov npoo ntawm lub vaj huam sib luag (tawm ntawm lawv los ntawm 10 cm). Tom ntej no, nws tseem yuav ntxig cov dowels rau hauv lub qhov, thiab tom qab ntawd ntsia cov panels rau phab ntsa.
Scope of application
Polyurethane ua npuas ncauj yog siv los tsim cov khoom siv hauv tsev (tub yees, lub tub yeeskoob yees duab), nrog rau kev sib cais ntawm cov cuab yeej tshwj xeeb ntawm lub xov tooj ntawm tes (tub yees, tankers).
ru tsev, qhov cua nkag, qhov chaw, hauv qab daus, phab ntsa sab nrauv ntawm cov tsev nyob thiab cov tsev lag luam yog insulated nrog cov khoom no.
