Lub Hauv Paus Molecular & Kev Xaiv Catalytic
Cov qauv molecular ntawm Ming Xu Chem's MXC-DMI (CAS 1739-84-0), uas yog ib qho catalyst curing based imidazole muaj zog.
Lub hauv paus ntawm MXC-R70 txhais nws qhov kev ruaj khov tshwj xeeb thiab kev tswj hwm meej ntawm PU formulations:
-
Heterocyclic Imidazole Nplhaib:Tsis zoo li cov qauv amine ib txwm muaj, lub nplhaib imidazole tseem ceeb muab qhov nruab nrab uas sib npaug zoo kawg nkaus rau kev sib xyaw thiab kev sib xyaw ua ke, ua kom muaj kev loj hlob ntawm cov cell.
-
Muaj Peev Xwm Ua Tau Ntau:Nrog rau tus nqi Hydroxyl ruaj khov (542 mg / KOH / g), nws muab cov peev xwm ua haujlwm zoo heev hauv polyol premix, uas tso cai rau cov qib thauj khoom qis dua kom ua tiav cov nyhuv catalytic xav tau.
Kev Kho Mob Nto & Kev Ua Tau Zoo
MXC-R70 yog cov tshuaj ua kua ua haujlwm siab uas tsim los rau kev sib txuas lus meej thiab cov khoom siv kho tshuab zoo tshaj plaws hauv PU systems.
Rau cov chaw tsim khoom ua npuas dej thiab cov tshuaj tsuag tas mus li, MXC-R70 ua haujlwm ua lub zog ua kom nrawm dua tom qab kho kom daws tau qhov teeb meem ntawm cov qauv:
-
Tshem tawm qhov kev sib txhuam ntawm qhov chaw:Nws yog tsim tshwj xeeb los tsav cov theem kawg ntawm cov tshuaj tiv thaiv isocyanate, daws qhov teeb meem ntawm qhov chaw brittleness (friability) feem ntau tshwm sim los ntawm kev demolding sai.
-
Kev nplaum zoo dua ntawm cov khoom siv:Los ntawm kev tsim cov polymer matrix uas tawv dua thiab kho tau tag nrho ntawm qhov sib txuas ua npuas ncauj, nws ua rau lub zog sib txuas rau cov khoom siv xws li hlau lossis ntoo zoo dua qub.
-
Kev Sib Txuas Lus ntawm HFO System:Nws ua haujlwm tau zoo heev rau cov tshuab ua kom HFO niaj hnub no thiab cov tshuab ua ke nrog dej, tswj tau qhov nce siab thiab ruaj khov zoo dua.
Kev Ua Haujlwm Zoo & Kev Ruaj Ntseg Ua Haujlwm
Peb tsom mus rau kev xa cov kev daws teeb meem ua tau zoo uas sib xyaw ua ke rau hauv koj cov khoom siv hauv Hoobkas thiab txhim kho kev nyab xeeb hauv chaw ua haujlwm:
-
Kev Ruaj Ntseg Npaj Rau Lub Caij Ntuj No:Nrog rau qhov chaw khov qis dua -10 ° C, cov tshuaj catalyst no tseem ruaj khov heev thiab tiv thaiv kev crystallization thaum lub sijhawm khaws cia thiab thauj mus los hauv huab cua txias.
-
Qhov Viscosity Tsawg Kawg Nkaus:Tsuas yog 10 mPa.s xwb, nws cov dej ntws zoo li dej ua kom yooj yim rau kev nqus, sib xyaw zoo meej, thiab kev ntsuas raug heev hauv cov tshuab ua npuas siab.
-
Cov Qauv Uas Muaj Tsw Qab Tsawg:Piv rau cov amines uas yaj sai sai, MXC-R70 muaj cov ntxhiab tsw qis dua, ua rau qhov chaw ua haujlwm hauv lub Hoobkas zoo dua thiab ua rau cov khoom kawg zoo nkauj dua.
