1. Txheej txheem cej luam ntawm urea-formaldehyde resin (UF)
Urea-formaldehyde resin, hu ua UF, feem ntau yog siv rau kev sib txuas ntoo thiab tau txhawb nqa cov ntawv loj hauv kev tsim cov plywood thiab particleboard.
2. Cov yam ntxwv
Urea-formaldehyde resin yog nyiam rau nws cov khoom siv raw thiab tus nqi qis. Nws muaj cov nplaum zoo heev, tiv taus cov acids tsis muaj zog thiab tsis muaj zog alkalis, thiab nthuav tawm cov rwb thaiv tsev zoo thiab hnav tsis kam. Txawm li cas los xij, nws tsim nyog sau cia tias formaldehyde raug tso tawm thaum lub sij hawm nws cov txheej txheem kho, thiab nws cov cua sov ua haujlwm thiab kev laus kuj tseem tsis muaj zog.
3. Daim ntawv
Urea-formaldehyde cobtuaj yeem nthuav tawm ntau yam ntaub ntawv xws li cob, hmoov, board thiab nplaum kom tau raws li kev thov sib txawv.
4. Cov txheej txheem siv tau
Urea-formaldehyde resin yog tsim rau ntau yam txheej txheem xws li txheej thiab compression molding, muab kev txhawb nqa rau kev tsim khoom ntawm ntau yam khoom.
5. Daim ntawv thov
Raws li cov kua nplaum feem ntau siv hauv kev lag luam ntoo,urea-formaldehyde cobyog siv dav hauv kev sib txuas ntawm cov ntoo, plywood, laminates, thiab xyoob thiab cov khoom ntoo. Piv txwv li, nws yog siv los ua cov ntoo plhaub ntawm cov plag tsev, cov rooj tog zaum, cov thawv ntim khoom, cov khoom siv textile, thiab cov khoom siv hauv tsev.
1. Txhim kho cov dej tsis kam ntawm urea-formaldehyde resin adhesive: Los ntawm kev ntxiv cov khoom sib txuas xws li txhuas sulfate thiab aluminium phosphate, nws cov dej tsis kam tuaj yeem txhim kho tau zoo.
2. Txhim kho kev laus tiv thaiv: Sib tov qee cov thermoplastic resins rau hauv urea-formaldehyde resin adhesives tuaj yeem txhim kho lawv txoj kev laus.
3. Txo cov ntsiab lus formaldehyde: Los ntawm kev kho cov txheej txheem synthesis, txo cov molar piv ntawm formaldehyde rau urea, los yog ntxiv formaldehyde scavengers (xws li urea, melamine, thiab lwm yam), lub hom phiaj ntawm kev txo cov formaldehyde cov ntsiab lus hauv urea-formaldehyde resin adhesives tuaj yeem ua tiav.
