Cov thev naus laus zis niaj hnub sandwich panel thiab cov ntaub ntawv polyurethane core
Ua ib qho kev tsim kho tshiab tseem ceeb hauv kev lag luam kev tsim kho, polyurethane sandwich panels tau dhau los ua cov khoom siv nyiam rau cov chaw tsim khoom lag luam, chaw cia khoom txias, chaw ua haujlwm huv si thiab lwm yam tsev. Cov khoom sib xyaw ua ke no muaj ob txheej ntawm cov hlau panels thiab lub plawv polyurethane ua npuas ncauj hauv nruab nrab vam khom lub kaw lus polyurethane catalyst rau nws qhov kev ua tau zoo heev. Peb cov MXC series catalysts tau tsim tshwj xeeb rau kev tsim cov sandwich panel, uas tuaj yeem txhim kho qhov zoo ntawm cov khoom thiab kev ua haujlwm zoo.
Catalyst system rau sandwich panels
Cov txiaj ntsig tshwj xeeb ntawmMXC-37 (DMAEE)cov tshuaj ua kom lub cev muaj zog
MXC-37 (2-(2-(dimethylamino)ethoxy)ethanol, CAS 1704-62-7) yog ib qho tshuaj amine catalyst uas coj ntau yam kev tshawb pom tshiab rau kev tsim cov vaj huam sib luag sandwich:
- Cov yam ntxwv tsis muaj pa phem, tsw ntxhiab tsawg: daws qhov teeb meem tsw ntxhiab ntawm cov tshuaj amine ib txwm muaj thiab txhim kho qhov chaw tsim khoom
- Kev ua npuas dej siab: tshwj xeeb tshaj yog rau cov dej ntau hauv cov qauv kom ntseeg tau tias ua npuas dej nthuav dav tag nrho
- Hom kev siv ob hom: siv tau ib leeg ua tus catalyst tseem ceeb lossis ua ke nrog BDMAEE
- Kev sib raug zoo dav dav: tsim rau ntau yam polyester thiab polyether polyol systems
Hauv cov kab ntau lawm ntawm cov vaj huam sib luag sandwich, MXC-37 tuaj yeem muab cov kab rov ua kom ruaj khov kom ntseeg tau tias cov khoom siv ua npuas ncauj sib npaug thiab sib xws, uas yog qhov tseem ceeb kom ntseeg tau tias qhov tiaj tus thiab qhov ntev ntawm cov vaj huam sib luag sandwich.
Kev tshawb pom tshiab ntawm thev naus laus zisMXC-15(kua potassium octanoate)
MXC-15 (CAS 3164-85-0), ua ib qho tshuaj catalyst isocyanurate zoo, muab kev txhawb nqa tseem ceeb rau kev tsim cov PIR sandwich panels:
- Tus nqi hloov pauv siab heev: txhawb nqa isocyanate trimerization thiab txhim kho kev ruaj khov thermal ua npuas ncauj
- Siv tau rau cov mis viscosity siab: ua kom zoo dua qhov fluidity thiab kev sib npaug ntawm cov khoom khov kho siab
- Kev lag luam thiab ua haujlwm tau zoo: qhov ntxiv tsawg tuaj yeem ua tiav cov txiaj ntsig zoo heev catalytic
- Kev sib phim PIR system: tsim tshwj xeeb rau polyisocyanurate sandwich panels
MXC-15 tuaj yeem txhim kho qhov tiv taus hluav taws thiab qhov ruaj khov ntawm cov sandwich panels, yog li lawv tseem tuaj yeem tswj tau cov khoom siv kho tshuab zoo heev hauv qhov chaw kub siab.
Lub luag haujlwm tseem ceeb ntawmcov tshuaj catalystshauv kev tsim cov vaj huam sib luag sandwich
Hauv cov txheej txheem tsim cov polyurethane sandwich panels, lub kaw lus catalyst cuam tshuam ncaj qha rau cov cim qhia tseem ceeb hauv qab no:
1. Ua npuas dej ua npuas ncauj: xyuas kom meej tias cov ntaub ntawv raw tag nrho cov qhov ntawm cov vaj huam sib luag kom tsis txhob muaj cov khoom tsis txaus
2. Kev kho qhov ceev: phim qhov ceev uas yuav tsum tau ua ntawm cov kab ntau lawm tas mus li kom muaj peev xwm ntau lawm ntau ntxiv
3. Cov qauv ntawm tes: cuam tshuam rau qhov thermal conductivity thiab lub zog kho tshuab ntawm lub vaj huam sib luag sandwich
4. Kev ua tau zoo ntawm kev nplaum: txiav txim siab qhov sib txuas ntawm lub zog ntawm cov khoom siv tseem ceeb thiab lub vaj huam sib luag
5. Kev ruaj khov ntawm qhov ntev: tiv thaiv kev hloov pauv ntawm vaj huam sib luag los ntawm kev ua npuas ncauj ntsws
Peb pab neeg ua haujlwm txawj ntse tuaj yeem muab cov tshuaj catalyst zoo tshaj plaws rau cov kab ntau lawm thiab cov khoom xav tau los ntawm kev tswj hwm qhov sib piv ntawm MXC-37 thiab MXC-15 kom raug, pab cov neeg siv khoom ua tiav:
- Ua kom cov kab ntau lawm ceev dua 20-30%
- Ua kom tus nqi tsim nyog ntawm cov khoom lag luam nce mus txog ntau dua 98%
- Txo kev siv hluav taws xob los ntawm 15-20%
