Xim Polyurethane los ntawm dej
Cov khoom siv trapezium uas siv dej tshwj xeeb, kev tshawb fawb txog tshuaj lom neeg hauv tebchaws, dej deionized, cov khoom siv dej thiab cov khoom siv tiv thaiv ib puag ncig thiab lwm yam khoom, tsis muaj benzene, tsev neeg, benzene qib ob thiab lwm yam organic solvents. Cov khoom no yog npaj los ntawm kev siv cov dej-raws li aliphatic polyurethane resin ua cov khoom siv ua zaj duab xis, HDI ua tus neeg sawv cev kho, ntxiv cov khoom siv zoo rau ib puag ncig thiab cov khoom pabcuam. Zaj duab xis puv nkaus, ci ntsa iab, xim ci. Kev nplaum zoo, tawv heev, tiv taus huab cua zoo heev.
Daim ntawv thov teb
Haum rau qhov chaw siab thiab qhov yuav tsum tau ua kom cov xim pleev xim sab saud zoo. Nws feem ntau yog siv rau kev kho kom zoo nkauj ntawm cov khoom siv hlau xws li lub thoob fais fab cua, cov khoom siv kho tshuab, cov tshuab tsim kho, cov yeeb nkab roj petrochemical, thiab lwm yam. Nws muaj kev tiv thaiv huab cua sab nraum zoov zoo heev thiab tiv thaiv xeb.
Kev kho qhov chaw
1. Qhov chaw yuav tsum huv thiab qhuav, thiab kev kho qhov chaw ntawm lub substrate yuav tsum ua tau raws li qhov yuav tsum tau ua.
2. Cov cuab yeej siv rau hauv kev tsim kho yuav tsum qhuav thiab huv si. 3.
3. Nws raug txwv tsis pub kov cov kua qaub thiab alkali thaum lub sijhawm ua xim pleev xim thiab txheej.
4. Lub sijhawm pleev xim yuav tsum tau tswj hwm nruj me ntsis, thaum qhov kub yog 25′C, lub sijhawm pleev xim yuav tsum tsis pub tsawg dua 12 teev.
5. Tsis tuaj yeem pleev xim tuab, ib zaj duab xis tsis pub tshaj 40μm lossis yuav npuas.
6. Kev tsim kho thiab ziab thiab kho thaum lub sijhawm cov av noo tsis pub tshaj 75%, qhov kub tsis pub tsawg dua 0 ℃ C, txwv tsis pub zaj duab xis tsis tuaj yeem kho tau tag nrho.
