Ua ntej yuav khoom, txhua tus neeg siv khoom xav txog qhov tsis zoo. Polyurethane ua npuas ncauj yog tsis muaj kev zam. Txog cov khoom no, uas yog hu ua PPU, txhua tus neeg tsim khoom tau hnov ntau cov ntaub ntawv niaj hnub no.
Cov khoom siv twg xaiv
Yog tias koj tau xav txog kev ua kom sov koj lub tsev, tej zaum koj yuav tau them sai sai rau qhov kev xaiv no ua cov rwb thaiv tsev thermal. Tej zaum nws yuav yog qhov kev daws teeb meem zoo tshaj plaws, vim tias nrog rau qhov tsis txaus, nws muaj ntau yam zoo.
Kev piav qhia
Polyurethane ua npuas ncauj, qhov tsis zoo uas koj yuav tsum paub txog ua ntej pib ua haujlwm ntawm rwb thaiv tsev, yog hom yas. Cov khoom los ntawm nws muaj cov qauv cellular. Cov muaj pes tsawg leeg ntawm polyurethane ua npuas ncauj muaj xws li ib tug gaseous tshuaj, uas yog muaj nyob rau hauv ib tug ntim ntawm 85 mus rau 90%. Tag nrho cov qauv muaj cov hlwb me, uas zoo sib cais los ntawm ib leeg los ntawm cov phab ntsa, nws yog cov hlwb uas muaj roj. Cov feem pua ntawm cov ntim yog cov khoom, uas yog covphab ntsa.
Qhov tsis zoo ntawm polyurethane ua npuas ncauj ua lub rhaub yog tsim nyog xav txog. Ntau yam ntawm polyurethane ua npuas ncauj tau siv ntau heev niaj hnub no, cov khoom yog nrov ntawm cov neeg siv khoom, vim nws yooj yim heev los ua nws, koj tuaj yeem ua nws ncaj qha ntawm qhov chaw tsim kho. Nyob rau hauv cov ntaub ntawv no, ob qho khoom ua kua yuav tsum sib tov, tom qab ntawd lawv yuav nkag mus rau hauv cov tshuaj tiv thaiv. Yog hais tias qhov tsim nyog proportions ntawm cov khoom xyaw raug soj ntsuam, ces ib tug polymer yuav synthesized, uas yog sawv cev los ntawm ib tug hardened ua npuas ncauj. Yog tias koj me ntsis hloov cov thev naus laus zis ntawm kev npaj, ces koj tuaj yeem tau txais polyurethane foams uas txawv ntawm cov yam ntxwv ntawm ib leeg. Ib txhia ntawm lawv yog haum rau insulating lub qhov rooj thiab qhov rais, thaum lwm tus neeg yog tsim rau thermal rwb thaiv tsev ntawm lub tsev ua los ntawm reinforced pob zeb los yog cib. Raws li rau peb hom, lawv tau dav siv rau cov kav dej. Yog li, nyob ntawm qhov sib npaug ntawm cov khoom, polyurethanes tuaj yeem tau txais ntawm cov zis, uas muaj ntau lub hlwb ntawm ntau qhov sib txawv. Lawv cov phab ntsa tuaj yeem muaj qhov tuab thiab muaj zog sib txawv.
Qhov tsis zoo ntawm polyurethane ua npuas ncauj
Polyurethane ua npuas ncauj, qhov tsis zoo uas yuav qhia hauv qab no, tuaj yeem siv rau ntau qhov chaw ntawm kev tsim kho. Txawm li cas los xij, ua ntej kev yuav khoom, nws yog ib qho tseem ceeb uas yuav tau ua tib zoo saib xyuas qhov tsis zoo ntawm cov khoom. Qhov tseem ceeb yog qhov tsis zoo ntawm lub hnub ci ntawm qhov chaw, uas tuaj yeem ua rau cov khoom hnav sai sai. Txhawm rau kom tsis suav nrog kev puas tsuaj ntawm lub tshav kub insulator, nws yog ib qho tsim nyog los muab kev tiv thaiv rau nws. Rau qhov no koj tuaj yeemsiv plaster, xim zoo tib yam thiab txhua yam ntawm cov vaj huam sib luag. Cov no yog txoj hauv kev uas cov neeg tsim khoom paub txog qhia.
Qhov tsis zoo ntawm Styrofoam ua cov rwb thaiv tsev phab ntsa yuav qhia rau koj paub yog tias nws tsim nyog siv. Kev tiv thaiv muaj pes tsawg leeg tuaj yeem tiv thaiv cov rwb thaiv tsev los ntawm ultraviolet hluav taws xob, thiab tseem ua rau polyurethane ua npuas ncauj zoo nkauj dua. Yog tias peb xav txog qhov kev tshem tawm no kom ntxaws ntxiv, nws tuaj yeem sau tseg tias kev khaws cia ntawm cov khoom ntawm polyurethane ua npuas ncauj yuav xav tau nyiaj ntau dua li peb ua haujlwm ntawm rwb thaiv tsev, uas suav nrog cov ntaub ntawv uas tsis xav tau kev tiv thaiv tsim nyog. Ntawm lwm yam, tsis yog txhua tus kws ua haujlwm hauv tsev tuaj yeem ua haujlwm plastering, nrog rau siv cov xim sib xyaw nrog cov khoom zoo. Raws li qhov tshwm sim, qhov saum npoo yuav dhau los ua qhov ntxim nyiam tsawg dua ua ntej ua kom zoo dua.
Ntxiv rho tawm
Yog tias koj txiav txim siab xaiv polyurethane ua npuas ncauj, qhov tsis zoo uas rau qee cov neeg siv khoom yuav zoo siab heev, ces nws tsim nyog xav tias cov khoom no yog thermal rwb thaiv tsev, uas, thaum raug hluav taws kub, pib smolder. Qhov tsis txaus no tau sau tseg los ntawm cov kws tshaj lij. Txawm tias muaj tseeb tias PPU ua raws li cov khoom siv hluav taws xob qeeb, nws tsis tuaj yeem tiv thaiv hluav taws ntawm 100%. Raws li kev faib tawm, qhov rwb thaiv tsev no belongs rau pawg flammability G-2. Qhov no qhia tau hais tias ignition yuav tsis tshwm sim thaum raug kub tsawg. Cov nplaim taws yuav tawm mus, cov txheej txheem yuav nres sai li sai tau thaum cov khoom tuaj yeem txias. Yog tias muaj kev kub ntxhov ntau dhau los yog qhov ua tau ntawm hluav taws kubib cheeb tsam ntawm rwb thaiv tsev, ces nyob rau hauv cov ntaub ntawv no polyurethane ua npuas ncauj yuav tsum tsis txhob siv.
Vim li cas koj yuav tsum tsis txhob xaiv PPU rau tsev rwb thaiv tsev
Qhov tsis zoo ntawm rwb thaiv tsev nrog polyurethane ua npuas ncauj, tau kawg, muaj nyob. Yog tias koj txiav txim siab los tsim cov rwb thaiv tsev thermal, qhov no yog qhov tseem ceeb uas yuav tsum tau xav txog. Yog tias siv tshuab tsis raug thaum lub sijhawm ua haujlwm, qhov no tuaj yeem cuam tshuam rau kev ua haujlwm ntawm lub tsev. Txhawm rau tshem tawm qhov no, nws yog ib qho tsim nyog yuav tsum coj mus rau hauv tus account qee yam khoom ntawm cov lus piav qhia. Yog li, PPU muaj qhov tsis tshua muaj vapor permeability - qhov no yog hais txog ntau yam khoom siv nruj. Yog hais tias muaj pes tsawg leeg yog siv rau cov phab ntsa, thaum ua cov hauv pem teb hauv pem teb los yog lwm yam panels, qhov no yeej yuav ua rau dampness ntawm sab hauv thiab hauv cov qauv. Dampness thiab pwm tuaj yeem hais txog qhov tshwm sim, tab sis yog tias khov tshwm sim, ces cov khoom txhawb nqa yuav ploj mus tas li. Cov neeg tsim kev paub dhau los feem ntau sau cov ntsiab lus no hauv lawv qhov kev tshuaj xyuas.
Xav tau kev tiv thaiv hluav taws
Yog tias koj txiav txim siab yuav polyurethane ua npuas ncauj, qhov tsis zoo ntawm cov neeg siv khoom tshuaj xyuas yuav tsum tau piav qhia meej rau koj. Tom qab tag nrho, nws yog lub sijhawm tsis zoo uas tib neeg pom thawj qhov chaw. Yog li, nws yog ib qho tsim nyog yuav tsum tau npaj rau qhov tseeb tias dhau sij hawm tus qauv yuav poob nws cov cua sov-insulating zoo, qhov zoo tshaj plaws, lawv tsuas tuaj yeem txo qis. Tsis tsuas yog kev laus ntawm cov khoom ua rau qhov tshwm sim no, tab sis kuj kub hloov pauv, nrog rau kev raug ultraviolet hluav taws xob. Heev feem ntau, thaum lub sij hawm thermal rwb thaiv tsev ua hauj lwm, txoj kev txau yog siv, qhov no muab kev tiv thaiv los ntawm cov teebmeem ntawm qhib hluav taws. Yog tias tsis muaj lub siab xav tsim kom muaj kev phom sij ntxiv, yuav tsum tau ua kom muaj kev nyab xeeb tsim nyog. Lawv kuj dhau los ua qhov kev siv nyiaj ntxiv, uas tsis yog ib txwm haum rau cov neeg siv khoom.
Minus: qhov yuav tsum tau coj mus rau hauv tus account lub zog ntawm cov qauv
Polyurethane ua npuas ncauj, qhov tsis zoo, kev tshuaj xyuas uas tau txheeb xyuas hauv tsab xov xwm, muab cov kev xav tau kom raug txiav txim siab lub zog ntawm cov qauv. Qhov no muaj tseeb nyob rau hauv rooj plaub thaum kev ua hauj lwm cuam tshuam nrog cua sov rwb thaiv tsev rau hauv qhov chaw nruab nrab ntawm cov phab ntsa. Tom qab ntawd, cov qauv pib nthuav dav, thiab tom qab ntawd cov npuas dej tuaj yeem ua rau puas tsuaj. Cov tswv tsev ntiag tug tsis tas yuav muaj lub sijhawm los ua kom raug.
Vim li cas cov neeg siv khoom qee zaum tsis kam siv polyurethane ua npuas ncauj
Yog tias koj txiav txim siab siv PPU, qhov tsis txaus, tawm tswv yim ntawm cov khoom koj yuav tsum raug ntsuas. Yog li, nws yog qhov tsis tsim nyog siv nws rau rwb thaiv tsev hauv lub tsev. Qhov no tuaj yeem ua rau cov dej lwg nyob rau sab nrauv phab ntsa hloov mus rau hauv chav. Nyob rau hauv rooj plaub no, cov phab ntsa pib khov, qhov tshwm sim dampness ua rau kis ntawm pwm, thiab tom qab ntawd cov ntoo pib rot. Hauv qhov xwm txheej no, cov phab ntsa tseem ntub txawm nyob rau lub caij ntuj sov, uas cuam tshuam tsis zoo rau microclimate ntawm thaj chaw. Cov kws tshaj lij qhia, yog tias nws tsis tuaj yeem siv cov khoom siv analog, siv cov khoom siv semi-rigid polyurethane ua npuas ncauj. Nyob rau tib lub sijhawm, nws yuav txaustxheej, thickness uas yog 30 millimeters.
