Sulfonated Melamine Formaldehyde ResinTxheej txheem ntau lawm:
Melamine-formaldehyde resin, ib tug polymer tau los ntawm cov tshuaj tiv thaiv ntawm melamine thiab formaldehyde.Kuj tseem hu ua melamine formaldehyde resin thiab melamine resin.Cov lus Askiv luv MF.Kev sib txuas sib txuas tshwm sim tshwm sim thaum lub sijhawm ua thiab molding, thiab cov khoom yog ib qho thermosetting resin infusible.Nws yog kev cai los sib sau ua ke rau nws thiab urea-formaldehyde resin li amino resin.Nws cov mis: Ntxiv 50mL formaldehyde tov thiab 0.12g urotropine rau hauv ib lub khob peb-caj dab nrog hluav taws xob stirrer, reflux condenser thiab tus pas ntsuas kub, do kom lawv tag nrho yaj, ces ntxiv 31.5g ntawm melamine nyob rau hauv stirring, thiab txuas ntxiv stirring Tom qab 5 feeb, kub. mus rau 80 ° C los pib cov tshuaj tiv thaiv;Thaum lub sij hawm cov tshuaj tiv thaiv, nws tuaj yeem pom meej tias cov tshuaj tiv thaiv kab mob hloov los ntawm turbid mus rau meej.2. Pib ntsuas cov nag lossis daus piv li ntawm 30-40 feeb tom qab tshem tawm cov tshuaj tiv thaiv.Thaum cov nag lossis daus piv mus txog 2: 2, tam sim ntawd ntxiv 0.15g (2-3 tee) ntawm triethanolamine, do sib npaug, tshem tawm cov da dej kub, thiab nres cov tshuaj tiv thaiv;kos 2 mL ntawm cov qauv los ntawm cov tshuaj tiv thaiv, txias rau hauv chav tsev kub, thiab ntxiv dej distilled dropwise nyob rau hauv stirring, Thaum ntxiv 2mL dej, tus qauv yuav turbid thiab tsis ua kom meej tom qab co.Nws txhais tau tias nag lossis daus piv mus txog 2:23.Ntawv impregnation.Ncuav lub prepolymer rau hauv ib lub tais petri qhuav, muab 15 daim ntawv lim rau hauv lub prepolymer thiab tsau rau 1-2 feeb;Tom qab ntawd muab nws tawm nrog tweezers thiab ua tib zoo siv lub iav pas nrig dai tawm ntawm cov prepolymer ntau dhau ntawm cov ntawv lim, thiab kho nws ntawm txoj hlua nrog ib lub khib kom qhuav.Lub dipping yog txawm thiab tag nrho.Cov tshuaj kho melamine formaldehyde resin tsis muaj xim thiab pob tshab, ruaj khov hauv cov dej kub npau npau, tuaj yeem siv tau ntawm 150 ° C, thiab muaj qhov tua tus kheej, arc tsis kam thiab cov khoom siv zoo.
Sulfonated Melamine Formaldehyde ResinNta:
1. Nrog rau kev siv tshuaj lom neeg ntau dua, kev sib koom ua ke muaj zog, dej tsis kam, tuaj yeem tiv taus cov dej kub npau npau rau ntau tshaj peb teev, thermal stability, muaj zog qis-kub curing muaj peev xwm, zoo abrasion tsis kam, ceev curing, tsis xav tau tus neeg sawv cev curing.
2. Cov khoom lag luam melamine muaj qhov zoo dua hardness thiab abrasion tsis kam tshaj li urea-formaldehyde resin khoom.Nws muaj kev tiv thaiv zoo dua rau cov tshuaj thiab hluav taws xob rwb thaiv tsev.Txawm li cas los xij, txheej nplaum yog yooj yim tawg tom qab kho.Nws tsis tsim nyog siv hloov kho melamine resin nplaum ib leeg.
3. Lub sij hawm cia luv luv thiab perishable.Nws tuaj yeem ua cov hmoov nplej kom ntev lub sijhawm cia.Hloov kho melamine resin yog kim dua.Nws yog siv rau hauv kev tsim cov yas veneer panels.Nws yog dav siv hauv rooj tog, tsheb tsim, thiab lwm yam.
