Polyurethane rigid ua npuas ncaujyog lub siab polymer tsim los ntawm kev kub siab txau los ntawm cov cuab yeej tshwj xeeb sib xyaw nrog isocyanate thiab polyether ua cov ntaub ntawv tseem ceeb hauv qab kev ua ntawm tus neeg sawv cev foaming, catalyst, nplaim taws thiab lwm yam khoom ntxiv.
Muaj ob hom polyurethane ua npuas ncauj: mos ua npuas ncauj thiab tawv ua npuas ncauj. Cov npuas mos muaj cov qauv qhib ntawm tes, thiab cov npuas tawv tawv muaj cov qauv kaw ntawm tes. Cov npuas mos yog muab faib ua ob hom: crust thiab non-crust.
Dab tsi yog qhov zoo ntawm Polyurethane rigid foam?
Raws li hom tshiab ntawm cov khoom siv thermal rwb thaiv tsev, tawv polyurethane ua npuas ncauj muaj rau qhov zoo dua piv nrog cov khoom siv thermal rwb thaiv tsev.
1.energy-txuag rwb thaiv tsev kaw qhov tus nqi yog ntau dua los yog sib npaug rau 97%, zoo heev thermal rwb thaiv tsev kev ua tau zoo.
2. hluav taws kub retardant. Polyurethane rwb thaiv tsev tau dhau los ntawm lub teb chaws ruaj hluav taws tua hluav taws thiab hluav taws-resistant yam ntxwv, thiab kev soj ntsuam combustion qib ntawm kev saib xyuas zoo thiab chaw soj ntsuam tau mus txog qib B.
3.airtight, suab rwb thaiv tsev, lub suab nqus kev ua tau zoo, qhov cuam tshuam los nag, lawg thiab lwm yam, muaj qhov txo qis.
4.green ib puag ncig tiv thaiv, tsis muaj formaldehyde, tsis nqus cov kab mob, tuaj yeem rov ua dua.
5.economic kev zoo nkauj, lub teeb yuag, txuag lub sij hawm tsim kho thiab qhov project nqi.
ruaj khov ntau lawm zoo, ceev kev tsim kho.
Dab tsi yog qhov yuav tsum tau saib xyuas rau polyurethane ua npuas ncauj?
1. Khaws cov kaus poom kom deb ntawm cov menyuam yaus.
2.Kev tho, hlawv thiab tshem tawm cov tso tsheb hlau luam raug txwv thiab kev tsim kho yog nqa tawm ntawm qhov hluav taws kub thiab cua sov.
3.Thaum kev thauj mus los thiab khaws cia, nws yog nruj me ntsis txwv tsis pub qhib hluav taws, tsis txhob cuam tshuam thiab raug tshav ntuj, thiab qhov kub ntawm lub tank yuav tsum tsis pub tshaj 45 degree.
4. Hnav cov looj tsom iav thiab hnab looj tes tiv thaiv thiab xyuas kom muaj cua zoo thaum tsim kho.
5.Yog ua npuas ncauj kov lub qhov muag lossis tawv nqaij, yaug tam sim ntawd nrog dej kom ntau thiab nrhiav kev kho mob yog tias tsim nyog.
6.Tsis txhob thim rov qab, lub tank yog nyob rau hauv siab nyob rau hauv ib txwm mob, pov tseg tsis zoo yuav muaj kev pheej hmoo ntawm tawg.
7.Cov khoom no muaj cov khoom siv isocyanate, thiab cov npuas uas tsis tau kho yog khaus khaus.
