1. Kev piav qhia txog 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 thov loj hauv kev tsim cov plywood thiab particleboard.
2. Cov yam ntxwv
Urea-formaldehyde resin yog qhov nrov vim nws cov khoom siv raw ntau thiab tus nqi qis. Nws muaj kev nplaum zoo heev, tiv taus cov kua qaub tsis muaj zog thiab cov alkali tsis muaj zog, thiab ua kom pom kev rwb thaiv tsev zoo thiab tiv taus kev hnav. Txawm li cas los xij, nws tsim nyog sau cia tias formaldehyde raug tso tawm thaum nws cov txheej txheem kho, thiab nws qhov kev tiv taus kub thiab kev laus tsis muaj zog.
3. Daim Ntawv
Urea-formaldehyde resintuaj yeem nthuav tawm hauv ntau hom xws li cov resin, hmoov, board thiab nplaum kom tau raws li cov kev xav tau ntawm daim ntawv thov sib txawv.
4. Cov txheej txheem siv tau
Urea-formaldehyde resin yog qhov tsim nyog rau ntau yam txheej txheem xws li txheej thiab compression molding, muab kev txhawb nqa rau kev tsim ntau yam khoom.
5. Daim Ntawv Thov
Raws li cov kua nplaum uas siv ntau tshaj plaws hauv kev lag luam ua ntoo,urea-formaldehyde resinsiv dav hauv kev sib txuas ntawm ntoo, plywood, laminates, thiab xyoob thiab cov khoom ntoo. Piv txwv li, nws yog siv los ua cov plhaub ntoo ntawm cov plag tsev, rooj tog, cov thawv ntim khoom, cov khoom siv textile, thiab cov khoom siv hauv tsev.
1. Txhim kho qhov tsis kam dej ntawm cov nplaum urea-formaldehyde resin: Los ntawm kev ntxiv cov neeg sawv cev sib txuas xws li txhuas sulfate thiab txhuas phosphate, nws qhov kev tiv thaiv dej tuaj yeem txhim kho tau zoo.
2. Txhim kho kev tiv thaiv kev laus: Kev sib xyaw qee cov thermoplastic resins rau hauv cov nplaum urea-formaldehyde resin tuaj yeem txhim kho lawv txoj kev tiv thaiv kev laus.
3. Txo cov ntsiab lus formaldehyde: Los ntawm kev kho cov txheej txheem tsim, txo qhov piv ntawm formaldehyde rau urea, lossis ntxiv formaldehyde scavengers (xws li urea, melamine, thiab lwm yam), lub hom phiaj ntawm kev txo cov ntsiab lus formaldehyde hauv urea-formaldehyde resin adhesives tuaj yeem ua tiav.
