Sulfonatedmelamine uaformaldehyderib esinyog hu uamelamine resin, kuj hu uamelamine formaldehyde coblos yogmelamine resin. Nws yog ib qho tseem ceeb triazine nplhaib compound.Melamine cobNws muaj cov dej tsis zoo, kev laus ua haujlwm, nplaim hluav taws kub, hluav taws kub tsis kam, tshuaj tiv thaiv thiab rwb thaiv tsev, thiab tuaj yeem siv rau hauv kev tsim cov khoom siv molding (cov khoom siv niaj hnub thiab cov khoom siv hluav taws xob), cov khoom siv ntoo (plywood, laminate flooring thiab laminated yas. boards)) thiab ua npuas ncauj yas, thiab lwm yam. Tsis tas li ntawd, melamine resinNws kuj yog siv dav hauv cov txheej txheem, cov nplaum ntoo, cov xim sib txuas sib txuas, cov khoom siv fiber ntau, cov ntaub ntawv ntub dej thiab cov cement dej txo cov neeg ua haujlwm.

Melamine cobmuaj cov kev siv loj hauv qab no:

1. Daim ntawv thov hauv kev lag luam tawv:

Hauv kev lag luam tawv,melamine resinyog ib qho uas feem ntau siv ua ntej tanning, retanning thiab filling resin, ntawm cov uas trimethylolmelamine resinyog cov amino resin siv dav tshaj plaws. Amino resin muaj cov txheej txheem tanning zoo ib yam li aldehyde tanning: lub prepolymer nkag mus rau hauv daim tawv nqaij, thiab raws li tus nqi pH txo, cov prepolymer cia li condenses rau hauv ib lub molecule nrog ib tug me me ntawm daim tawv nqaij, thiab lub active -NHCH 2 OH thiab collagen nyob rau hauv molecule yog dhau los ntawm. Cov amino pawg ntawm cov saw peptide yog condensed los tsim covalent cross-linking system kom ua tiav lub hom phiaj ntawm tanning. Nyob rau tib lub sijhawm, cov amino resin muaj cov nyhuv filling. Braum, Aloysins thiab lwm tus siv GPS, IR, 1H-NMR, 13C-NMR thiab lwm yam kev tshawb nrhiav, thiab pom tias cov resin no muaj ob qho tib si tanning thiab sau cov khoom, thiab tuaj yeem sau ntau ntawm cov collagen fibers ntawm cov tawv nqaij. ua kom tawv nqaij lub cev plump. nyhuv.Melamine cobtanning tus neeg sawv cev yog siv nyob rau hauv lub retanning ntawm chrome-tanned lub teeb tawv kom ua tiav tawv zoo grained, tag nrho cov pob txha, pom tseeb thickening, zoo whitening nyhuv thiab zoo lub teeb ceev ceev. Thiab nws muaj kev sib raug zoo nrog lwm tus neeg ua haujlwm tanning. Siv ua ke nrog zaub tanning tus neeg sawv cev, nws tuaj yeem txhawb kev nkag mus thiab nqus ntawm cov zaub tanning cov neeg ua haujlwm, thiab ua rau kom muaj kev puas tsuaj thiab huab cua tsis kam ntawm tawv. Yog hais tias siv rau retanning ntawm suede, raising nyhuv yog zoo.

2. Daim ntawv thov hauv kev lag luam ntawv:

Lub hauv paus ntsiab lus thiab kev ua tau zoo ntawm kev siv los ua tus neeg sawv cev ntub dej thiab cov tshuaj tiv thaiv dej. Vim lubmelamine formaldehyde cobmuaj methylol, nws tuaj yeem tsim cov qauv etherified ntawm cov pob fiber ntau. Qhov kev sib txuas ntawm qhov sib txawv ntawm cov molecules no ua rau cov dej tsis kam thiab ua rau daim ntawv. Yuav kom ua tiav cov nyhuv ntawm lub zog moisturizing, nws yog tsuas yog siv los ua tus neeg sawv cev ntub dej thiab cov tshuaj tua dej hauv kev lag luam ntawv. Trimethylol melamine feem ntau yog siv nyob rau hauv daim ntawv kev lag luam, tab sis vim hais tias nws stability, dej solubility thiab dawb formaldehyde cov ntsiab lus tsis zoo tagnrho, thiab nws muaj ib tug tsis zoo tshwm sim ntawm whiteness thiab durability ntawm daim ntawv, hloov melamine yog dav siv tam sim no. resin.

3. Siv ua ceramic thiab cement dispersant:

Melamine formaldehyde cobsulfonate yog ib qho zoo anionic surfactant nrog rau qhov chaw ua haujlwm thiab lwm yam khoom muaj txiaj ntsig. Nws feem ntau yog siv los ua cov khoom ua kom muaj txiaj ntsig zoo lossis cov dej txo qis hauv ceramics, cement thiab pob zeb hauv tsev thiab txawv teb chaws. Nws cov txheej txheem ntawm kev ua haujlwm feem ntau yog: hom dej txo tus neeg sawv cev no muaj cov haujlwm ntawm adsorption, dispersion thiab lubrication, yog li kev ua haujlwm ntawm cov pob zeb tuaj yeem txhim kho los ntawm kev siv dej tsawg, thiaj li ua tiav lub hom phiaj ntawm kev txo cov dej. Vim tias qhov sib xyaw ntawm cov dej sib xyaw txo qis, qhov pores hauv cov pob zeb yuav txo qis, ua rau cov cement ntau ntom thiab ua kom muaj zog, uas tuaj yeem txo cov cement. Vim yog qhov infiltration ntawm cov dej txo tus neeg sawv cev, kev loj hlob ntawm cov khoom siv cement hydration qeeb, thiab sulfonated qhob network qauv yog ntau ntom, uas yog qhov zoo rau kev nce lub sij hawm ntev ntawm cov pob zeb.

4. Siv los ua ntoo nplaum:

Hauv kev lag luam ntoo,sulfonatedmelamine uaformaldehyderib esinfeem ntau yog siv los ua cov nplaum. Vim nws cov tshuaj lom neeg ua haujlwm siab, thaum nws nkag mus rau hauv cov khoom ntoo, kev sib txuas ntawm kev sib txuas thiab hardening ceev nrawm dua, thiab nws tuaj yeem ua rau thermally hardened los yog hardened nyob rau hauv chav tsev kub yam tsis muaj lwm yam hardeners, yog li tsim ib tug bonding nyhuv. Vim nws zoo thermal stability, dej tsis kam thiab tshuaj lom neeg, nws yog dav siv nyob rau hauv ntoo raws li panels, ntoo, kev tsim kho, ntawv ntim thiab lwm yam teb. Lub hom phiaj ntawm daim teb no yog yuav ua li cas kov yeej qhov tshwm sim tawg thiab tau txaismelamine formaldehyde cobnrog nruab nrab yooj. Kev daws tam sim no yog ntxiv polyvinyl cawv, vim tias nws tuaj yeem cuam tshuam nrog formaldehyde los tsim cov polyvinyl acetal, uas yog sib npaug ntawm cov resin, txhawm rau txhawm rau thaiv peb lub nitrogen heterocyclic molecules hauv MF resin molecules los ntawm kev txav mus, ua si lub zog thiab tiv thaiv kev tawg.

5. Siv ua ntaub luam ntawv thiab dyeing xov tus neeg sawv cev:

Hauv kev lag luam textile,sulfonatedmelamine uaformaldehyderib esinthiab nws cov derivatives yog cov ntaub ntawv tseem ceeb rau kev npaj cov ntaub ntawv luam tawm, dyeing thiab xov cov neeg ua haujlwm. Nws cov txheej txheem ntawm kev ua haujlwm yog tsuas yog siv los ua qhov hloov pauv ntawm qhov chaw thiab sib txuas tus neeg sawv cev rau cov ntaub, yog li txhim kho cov khoom tiv thaiv shrinkage, anti-wrinkle thiab dej-ntxuav khoom ntawm paj rwb ntaub. Txawm li cas los xij, vim tias qhov tsis zoo cia ruaj khov, kev xav ntawm tes ntxhib thiab nqus tau yooj yim ntawm cov tshuaj chlorine thiab yellowing ntawm cov ntaub tom qab daim ntawv thov, ntau thiab ntau cov kev tshawb fawb tau ua tiav ntawm nws qhov kev hloov kho. Tam sim no, methanol etherifiedmelamine resinyog siv, thiab formaldehyde modifiers xws li cyclic vinylidene urea thiab borax yog ntxiv kom tau txais kev hloov kho.melamine formaldehyde cobtus neeg sawv cev xov nrog ultra-low aldehyde thiab siab stability. Cov hloov kho resin yog siv los tiv thaiv shrinkage thiab anti-wrinkle ntawm bleached poplin Tiav, yellowing thiab chlorine poob yog txhim kho, thiab ntxuav kuj zoo dua. Ntxiv mus, lub sijhawm cia ntawm tus neeg sawv cev tiav yog 210-365 d, cov ntsiab lus dawb formaldehyde yog 0.3%, thiab cov ntsiab lus khoom yog li 40%.
