Intshayelelo
Ii-elastomer zePolyurethane ziluhlobo lwee-polymers eziguquguqukayo nezisebenza kakuhle ezisetyenziswa kumashishini aquka iimoto, ezokwakha, izihlangu, kunye nemizi-mveliso. Indibaniselwano yazo eyahlukileyo yokuqina, ukuguquguquka, kunye nokumelana neekhemikhali kuzenza zilungele iimeko ezifuna amandla. Icandelo elibalulekileyo, elihlala lingajongwa ekuveliseni ii-elastomer ze-polyurethane ezikumgangatho ophezulu yinkqubo ye-catalyst—ingakumbi ii-catalysts ze-amine, ezinceda ukulawula iprofayili yempendulo kunye neempawu zokugqibela zezinto.
Kwi-MINGXU NEW MATERIALS, sigxile ekuveliseni ii-polyurethane catalysts ezisebenza kakuhle. Enye yeemveliso zethu eziphambili, i-MXC-37 (DMAEE), idlala indima ebalulekileyo kwizicelo ezahlukeneyo ze-elastomer ngokuphucula i-reaction kinetics ngelixa iqinisekisa ukukhutshwa okuphantsi kunye nevumba elincinci.
IiCatalysts zePolyurethanekwiiNkqubo ze-Elastomer
Kwiifomyula ze-polyurethane elastomer, ii-catalysts zilawula izinga leempendulo ezimbini eziphambili:
1. I-gelling reaction (i-polyol kunye ne-isocyanate)
2. Impendulo yokuvuthela (amanzi kunye ne-isocyanate)
Ngokungafaniyo namagwebu, ii-elastomers zihlala zifuna ukuvuthuzwa okuncinci ukuze kugcinwe ukuqina kwesakhiwo. Nangona kunjalo, kwezinye izicelo ezifana nee-microcellular elastomers okanye i-reaction injection molding (RIM), ibhalansi entle phakathi kwe-foaming kunye ne-gelling ibalulekile ekufezekiseni uxinano olufunekayo, ukuqina, kunye nokugqitywa komphezulu.
I-MXC-37 (i-DMAEE): I-Amine Catalyst eSebenzayo kakhulu ye-Elastomers
I-MXC-37, ekwaziwa ngokuba yi-2-dimethylaminoethylethanol (DMAEE), sisincedisi se-amine esemagqabini esenzelwe ukunika ukusebenza okugqwesileyo kwiinkqubo ze-elastomer kunye ne-microcellular. Isebenza ngakumbi kwiifomyula ezinomthamo wamanzi amaninzi, apho ulawulo lwe-foam kunye nolawulo lwevumba lubaluleke kakhulu.
Iingenelo eziphambili ze-MXC-37 kwi-Elastomers:
Ivumba Eliphantsi, Uyilo Olungakhuphi Umoya:Njengesixhobo sokunciphisa ukukhutshwa kwegesi kunye nevumba eliphantsi, i-MXC-37 inciphisa ivumba le-amine elibonakalayo kwiindawo ezigqityiweyo ze-elastomer—ingakumbi ezibaluleke kakhulu kwiindawo zangaphakathi zeemoto nakwiimpahla zabathengi.
Umsebenzi Ophezulu Wokwenza Igwebu:Kwanakwiinkqubo ze-elastomer ezinomxholo we-foam ophantsi okanye olawulwayo, i-MXC-37 ixhasa ulwakhiwo lweeseli olufanayo kunye nolawulo loxinano oluncinci xa kufuneka iziphumo ze-microcellular.
Ukuhambelana Okugqwesileyo:I-MXC-37 iyahambelana neenkqubo ezahlukeneyo ze-polyester kunye ne-polyether, nto leyo eyenza ukuba ifaneleke kwii-elastomers ezithambileyo neziqinileyo, kunye ne-foam ethambileyo esekelwe kwi-ester kunye ne-rigid foam packaging.
Ukusetyenziswa okuguquguqukayo: Isetyenziswa rhoqo kwi:
Ii-microcellular polyurethane elastomers (umz., izihlangu, iindawo zokubeka iingalo)
Iinkqubo ze-RIM (iibhampa zeemoto, iiphaneli)
Amagwebu e-elastomer aguquguqukayo kwaye aqinileyo
Ii-elastomers zolwakhiwo kunye ne-insulation
Kutheni Ufanele Ukhethe iMXC-37 kwiNkqubo Yakho ye-Elastomer?
Ukuveliswa kwee-elastomer ze-polyurethane ezisebenza kakuhle kufuna ukuchaneka, ukuhambelana, kunye nolawulo. I-MXC-37 inikezela konke oku ngelixa inceda abaqulunqi bezinto ezifunekayo ukuhlangabezana nemigangatho engqongqo yokusingqongileyo kunye nempilo yomsebenzi. Nokuba uphuhlisa iindawo zemoto ezilula okanye izinto zoshishino ezihlala ixesha elide, i-MXC-37 iphucula zombini inkqubo kunye nomgangatho wemveliso.
Isiphelo
Njengoko imfuno yeenkqubo ze-polyurethane elastomer ezicocekileyo nezisebenza kakuhle iqhubeka ikhula, ukukhetha i-catalyst efanelekileyo kubaluleke kakhulu kunangaphambili. I-MXC-37 (DMAEE) inika ukusebenza, ukuthobela okusingqongileyo, kunye nokuguquguquka okufunekayo ukuhlangabezana neemfuno zokuvelisa zanamhlanje.
Qhagamshelana nathi namhlanje ukuze ufunde indlela iMXC-37 enokuyenza ngcono ngayo ifomyula yakho ye-polyurethane elastomer.
