Ua npuas dej polyurethane txau (SPF) yog cov khoom siv rwb thaiv tsev thiab kaw uas siv dav hauv kev tsim kho thiab kev tsim khoom. Nws yog tsim los ntawm kev sib xyaw isocyanate thiab polyol resin - cov khoom uas teb los ua npuas dej nthuav dav. Cov khoom siv ntau yam no txhim kho kev siv hluav taws xob zoo, muab kev txhawb nqa cov qauv, thiab txhim kho kev tswj dej noo thiab cua hauv cov tsev. Txawm li cas los xij, kev ua tau zoo ntawm cov npuas dej txau tsis yog txiav txim siab los ntawm nws cov qauv - nws kuj tseem cuam tshuam los ntawmcov tshuaj polyurethane catalysts, xws liMXC-BDMA, uas ua lub luag haujlwm tseem ceeb hauv qhov zoo ntawm ua npuas ncauj, cov qauv, thiab kev nplaum.
Hom Tshuaj Tsuag Ua Npuas Ncauj: Qhov Ceev Siab vs. Qhov Ceev Qis
Cov tshuaj tsuag ua npuas ncauj muaj ob hom tseem ceeb:siab ceevthiabqis-density, txhua tus haum rau cov chaw thov sib txawv.
1. Ua Npuas Ncauj Tsuag Uas Muaj Qhov Ceev Heev
Feem ntau, cov tshuaj tsuag ua npuas dej uas muaj cov khoom ntom ntom (HD) muaj ib qhoqhov ceev ntawm 2.5 txog 3 lbs/ft³Nws yog ib qho khoom ruaj khov, ruaj khov, thiab tiv taus dej, ua rau nws zoo tagnrho rau:
- Cov txheej txheem ru tsev
- Phab ntsa sab nraud
- Cov thoob dej thiab cov kav dej rau kev lag luam
- Cov haujlwm rwb thaiv tsev lag luam
Nws cov qauv ruaj khov ntxiv kev txhawb nqa rau cov chaw xws li ru tsev thiab phab ntsa, pab ua kom lub tsev siv tau ntev. Vim nws qhov permeability tsawg kawg nkaus thiab muaj zog lo, HD tsuag ua npuas ncauj feem ntau siv rau hauvsab nraum zoovthiabib puag ncig uas raug tshav ntuj.
2. Ua Npuas Ncauj Tsuag Tsawg
Cov tshuaj tsuag ua npuas dej qis (LD) muaj ib qhoqhov ceev ntawm qhov tseem ceeb ntawm kwv yees li 0.5 lbs / ft³thiab feem ntau hu uaqhib-cell tsuag ua npuas ncaujHom no mos dua thiab yoog tau dua, ua rau nws:
- Sau cov qhov khoob thiab cov qhov uas nyuaj mus txog
- Muab kev tiv thaiv suab zoo heev
- Ua haujlwm ua cov pa thiab cov pa dej thaiv hauvsab hauv tsevcov ntawv thov
Nws feem ntau siv rau hauv:
- Cov qhov phab ntsa
- Cov attics uas tsis muaj cua nkag
- Qab nthab thiab pem teb chaw
Vim tias nws tso cai rau kev tswj hwm cov pa dej permeability, LD tsuag ua npuas ncauj pab tswj cov dej noo sab hauv tsev yam tsis muaj nws ntes rau hauv cov phab ntsa.
Qhov Tseem Ceeb ntawm Cov Catalysts hauv Cov Tshuaj Tsuag Ua Npuas Ncauj
Cov txheej txheem ua npuas dej polyurethane vam khom cov tshuaj lom neeg kom raug kom ua tiav qhov kev nthuav dav, lub zog, thiab kev kho kom zoo. Cov catalysts yog qhov tseem ceeb hauv kev tswj hwm qhovkev sib xyaw ua ke ntawm polyol thiab isocyanate, xyuas kom meej tias muaj kev nce siab tas li thiab cov qauv cell zoo tshaj plaws.
Ntawm lawv,cov tshuaj amine catalystssiv dav rau lawv lub peev xwm los tswj ob qho tib sikev ua kom cov kua nplaum(polyol-isocyanate) thiabtshuab(dej-isocyanate) cov tshuaj tiv thaiv. Qhov sib npaug zoo ntawm cov tshuaj tiv thaiv no yog qhov tseem ceeb los tsim cov ua npuas dej uas muaj qhov ruaj khov zoo, cov qauv cell sib xws, thiab kev nplaum.
