Sulfonated Melamine Formaldehyde Resin Dawb Hmoov CAS 9003-08-1
Lus piav qhia luv luv:
Sulfonated melamine formaldehyde (melamine), feem ntau hu ua melamine, protein essence, molecular mis yog C3H6N6, IUPAC lub npe hu ua "1,3, 5-triazine-2,4, 6-triamine", yog triazine-muaj heterocyclic organic compounds raws li tshuaj. raw khoom.Nws yog dawb monoclinic siv lead ua, yuav luag tsis muaj ntxhiab, me ntsis soluble hauv dej (ntawm chav tsev kub 3.1g / L), soluble hauv methanol, formaldehyde, acetic acid, kub glycol, glycerin, pyridine, thiab lwm yam, insoluble hauv acetone, ether, teeb meem. rau tib neeg lub cev, tsis tuaj yeem siv rau hauv kev ua zaub mov lossis khoom noj khoom haus ntxiv.

Sulfonated Melamine Formaldehyde ResinChemical Properties:
Tsis-flammable, ruaj khov ntawm chav tsev kub.Cov tshuaj aqueous yog qaug zog alkaline (pH = 8), thiab tuaj yeem tsim cov melamine ntsev nrog hydrochloric acid, sulfuric acid, nitric acid, acetic acid, oxalic acid, thiab lwm yam. , thiab nyob rau hauv me ntsis acidic tej yam kev mob (pH = 5.5-6.5) condensation nrog methyl derivatives los tsim resins.Tom qab hydrolysis los ntawm muaj zog acid los yog muaj zog hauv paus aqueous tov, pawg amine yog maj mam hloov los ntawm hydroxyl pawg, thawj zaug tsim melamine, ces ntxiv hydrolysis ua melamine monoamides, thaum kawg tsim melamine.
Sulfonated Melamine Formaldehyde Resin Siv:
Sulfonated melamine formaldehyde resin dej reducer belongs rau cov dej-soluble polymer resin, tsis muaj xim, zoo thermal stability, nyob rau hauv kev siv cov qhob sib tov, zoo dispersion ntawm xis mas, siab dej txo tus nqi, thaum ntxov zog nyhuv yog tseem ceeb, yeej tsis cuam tshuam rau cov pob zeb. teem sij hawm thiab cov ntsiab lus roj.Melamine formaldehyde resin hom dej txo tus neeg saib xyuas dej txo tus nqi yog siab, nyob rau hauv ntau npaum li cas, dej txo tus nqi yuav ncav cuag 15% ~ 25%, lub durability ntawm qhob ua tau zoo heev.
Vim muaj qhov sib xyaw ntawm huab cua nkag, cov pob zeb ntxiv nrog cov khoom no muaj cov khoom zoo impervious thiab Frost resistant.Nws tsis muaj chlorine ntsev thiab yuav tsis corrode steel bar.Lub zog thaum ntxov tau pom tseeb, thiab tom qab ntawd lub zog tau nce siab heev.Lub zog ntawm 3D thiab 7d tuaj yeem nce ntxiv los ntawm 20% ~ 25% piv nrog cov qauv ntsuas, thiab lub zog ntawm 28d tuaj yeem ncav cuag 120% ~ 135% piv nrog cov qauv ntsuas.Melamine formaldehyde resin dej-txo tus neeg sawv cev yog tsim rau kev lag luam thiab pej xeem kev tsim kho engineering, precast, cam khwb cia-nyob rau hauv qhov chaw, thaum ntxov lub zog, siab zog, ultra siab zog pob zeb, steam curing qhob, super impermeable qhob engineering.
Tsis tas li ntawd, nws tseem tuaj yeem siv rau cov khoom siv gypsum, xim cement khoom thiab refractory pob zeb thiab lwm yam haujlwm tshwj xeeb.
