1, PUR kub yaj nplaum nplaum yog ib yam ntawm cov nplaum uas tsis muaj qhov hnyav / kev daws teeb meem, tsis zoo li cov kua nplaum ua kua nplaum uas yuav tsum muaj cov txheej txheem ziab, yuav tsis ua rau muaj kuab paug ib puag ncig lossis teeb meem lom, PUR kub yaj nplaum tsis qab, Europe tau pib siv. PUR kub yaj nplaum nplaum ntau xyoo dhau los, yog cov khoom ntsuab.
2, PUR kub yaj nplaum, ua haujlwm yooj yim. Ob lub nplaum tuaj yeem kho tau hauv lub sijhawm luv luv yam tsis muaj ziab, txhim kho kev ua haujlwm thiab txuag lub sijhawm.
3. PUR kub yaj nplaum muaj cov cua kub zoo heev, tiv taus txias, dej vapor tsis kam, tshuaj lom neeg thiab hnyav ua haujlwm. Vim yog cov yam ntxwv tsis zoo ntawm PUR roj hmab ib zaug reacted (uas yog, nws yuav tsis yaj thaum rhuab dua), cov coated hlau phaj tuaj yeem nyob ruaj khov ntawm -40 degree C txog 150 degree C, thiab cov khoom zoo yog ruaj khov dua. thiab tsim nyog rau kev ua cov khoom xa tawm.
4, PUR kub yaj nplaum ntim yog ntim cov ntawv txhuas ntawv ci, cov kua nplaum yuav tsum tau muab ntim cov khoom siv, kom zoo dua ua kom zoo ntawm cov yeeb yaj kiab. Lub tshuab kub yaj kua nplaum tshuab melts PUR kua nplaum los ntawm cua sov nws hauv kev sib cais ntawm huab cua. Hauv kev lag luam rooj tog kev cai, PUR kua nplaum feem ntau yog siv rau hauv kev sib khi ntawm cov vaj huam sib luag zoo nkauj, hauv daim ntawv thov ntawm ntug sealing, qhov zoo thiab cov khoom ua tau zoo ntawm PUR roj hmab foob zoo dua li EVA kua nplaum, hauv daim ntawv thov, PUR kua nplaum thiab feem ntau. ntawm cov phaj sib txuas, yooj yim rau yob txheej, cov yam ntxwv ntawm kev tsim khoom tas mus li, yog li ntawd nws yog ntau thiab ntau daim ntawv thov nyob rau hauv zus tau tej cov hniav panels.
5, PUR kub yaj ntug sealing kua nplaum nyob rau hauv zus tau tej cov ntoo veneer vaj huam sib luag rooj tog, tsis tsuas yog yuav txhim kho cov xim tsis kam ntawm ntoo veneer ua, tib lub sij hawm, nyob rau hauv cov tsoos kub yaj kua nplaum ntug sealing thiab ces kub nias veneer ua hauj lwm, lub nplaum txheej vim tias qhov kub ntawm cov cua sov resistant siab tshwm sim los ntawm cov khoom ntug poob, Yog li ntawd, cov tsoos kub yaj nplaum nplaum ntug sealing tshuab txiav txim siab tias cov ntoo veneer tsuas yog siv cov txheej txheem ntawm thawj veneer thiab ces ntug sealing, thiab tom qab ntawd inevitably tsim kua nplaum tawg tom qab ntug sealing thiab txo cov khoom qib. Txawm li cas los xij, kev siv cov kub-kub PUR kub yaj nplaum rau ntug sealing zoo daws qhov teeb meem. Tsis tas li ntawd, cov txheej txheem ntawm PUR sealing kua nplaum kuj tseem rov qab tsis tau, thiab kev siv PUR sealing thev naus laus zis tuaj yeem txhim kho qhov zoo thiab kev pabcuam lub neej ntawm cov khoom siv rooj tog zaum hauv tsev xws li chav dej, txee, rooj tog ntoo, thiab rooj tog zaum.
