Daim Ntawv Thov Polyurethane Catalyst hauv Sandwich Panels

Cov tshuaj polyurethane catalysts ua lub luag haujlwm tseem ceeb hauv kev tsim cov polyurethane sandwich panels, uas siv dav hauv ntau yam lag luam rau lawv cov khoom rwb thaiv tsev zoo heev, lub zog ntawm cov qauv, thiab lub teeb yuag. Kev nkag siab txog kev siv cov tshuaj catalysts no tuaj yeem muab kev nkag siab txog cov txheej txheem tsim khoom thiab cov txiaj ntsig ntawm kev siv polyurethane sandwich panels.

Sandwich Panel yog dab tsi?

Feem ntau, lub vaj huam sib luag sandwich muaj peb txheej: lub plawv tsis muaj zog ua los ntawm polyurethane ua npuas ncauj thiab ob daim ntawv sab nraud uas muab kev txhawb nqa thiab kev tiv thaiv. Cov khoom siv tseem ceeb, polyurethane ua npuas ncauj, yog xaiv rau nws cov khoom rwb thaiv tsev zoo dua, lub teeb yuag, thiab lub zog kho tshuab. Cov ntawv sab nraud tuaj yeem ua los ntawm ntau yam khoom siv, suav nrog PPGI (pre-coated galvanized hlau), PPGL (pre-coated aluminized zinc hlau), txhuas ntawv, lossis ntawv ci. Cov ntawv no tau tsim lossis slotted raws li qhov yuav tsum tau ua ntawm lub tshuab ua roller, tsim kom muaj vaj huam sib luag ruaj khov thiab rwb thaiv tsev.

Lub Luag Haujlwm ntawm Polyurethane Catalysts

Cov tshuaj polyurethane catalysts xws liMXC-Tthiab MXC-BDMA yog qhov tseem ceeb hauv kev tsim cov polyurethane ua npuas ncauj, uas tsim lub hauv paus ntawm cov vaj huam sib luag sandwich. Cov catalysts no pab txhawb cov tshuaj tiv thaiv ntawm cov polyurethane precursors, ua rau muaj cov polymer hnyav molecular siab. Feem ntau, plaub lossis ntau dua cov khoom ua kua uas muaj polyurethane precursors raug ntsuas thiab sib xyaw thaum lub sijhawm ua tiav los tsim cov polyurethane ua npuas ncauj. Lub luag haujlwm ntawm cov catalysts yog kom ua kom cov tshuaj tiv thaiv no sai dua, kom ntseeg tau tias muaj txiaj ntsig zoo thiab tswj tau cov npuas ncauj.

Cov Txheej Txheem Tsim Khoom

Kev tsim cov polyurethane sandwich panels muaj ntau theem:

1. Kev Ntsuas thiab Kev Sib Tov: Cov khoom ua kua uas muaj cov polyurethane precursors raug ntsuas thiab sib tov kom raug. Cov kauj ruam no yog qhov tseem ceeb rau kev ua tiav cov yam ntxwv ua npuas ncauj xav tau.

2. Kev Ua Npuas Ncauj: Cov khoom sib xyaw ua ke ua rau muaj kev ua npuas ncauj, ua los ntawm cov tshuaj catalysts MXC-T thiab MXC-BDMA. Cov tshuaj catalysts ua kom qhov kev ua npuas ncauj tshwm sim ntawm qhov nrawm zoo tshaj plaws, tsim cov npuas ncauj zoo thiab ruaj khov.

3. Lamination: Lub plawv ua npuas ncauj yog laminated ntawm ob daim ntawv sab nraud, uas tau tsim lossis slotted raws li qhov yuav tsum tau ua ntawm lub tshuab ua lub menyuam.

4. Kev Kho: Lub vaj huam sib luag sandwich uas tau sib dhos ua ke tau kho kom cov ua npuas ncauj nthuav dav thiab lo rau cov ntawv sab nraud, ua rau muaj cov qauv ruaj khov thiab ruaj khov.

Cov txiaj ntsig ntawm Polyurethane Sandwich Panels

1. Kev Rwb Thaiv Kub: Polyurethane ua npuas ncauj ruaj khov muaj kev rwb thaiv kub zoo heev, ua rau cov vaj huam sib luag sandwich zoo tagnrho rau cov ntawv thov uas tswj qhov kub thiab txias tseem ceeb heev.

2. Lub Zog Ntawm Cov Qauv: Kev sib xyaw ua ke ntawm lub plawv ua npuas ncauj ruaj khov thiab cov ntawv sab nraud ruaj khov muab lub zog ntawm cov qauv, ua rau cov vaj huam sib luag haum rau cov ntawv thov uas muaj kev thauj khoom.

3. Lub teeb yuag: Txawm hais tias lawv lub zog, cov vaj huam sib luag polyurethane sandwich yog lub teeb yuag, txo cov nqi thauj mus los thiab kev teeb tsa.

4. Kev Siv Tau Ntau Yam: Cov vaj huam sib luag no siv tau rau ntau yam kev siv, suav nrog kev tsim kho vaj tse, cov tub yees, thiab kev thauj mus los.
