Ob-tiv thaiv polyurethane nplaum yog cov nplaum ntawm ortocyanates, nrog lawv cov pawg molechanates muaj cov pab pawg urethans (-Nhcoo-) lossis ownocyanate pawg (-nco). Cov nplaum no feem ntau muaj ob feem: yog oocyanate tivthaiv (tus neeg kho mob bco, uas muaj cov neeg tsis zoo ntawm hydroxyl (uas muaj pawg hydroxyl.
Ob-tiv thaiv polyurethane cov nplaum muaj cov khoom ua tau zoo yav tom ntej kev ua tau zoo, tshuaj lom neeg ruaj khov, thiab kub - kub tsis kam. Cov ntawv thov feem ntau suav nrog cov khoom siv potting, txhuas honeycomb nplaum, purification boardesive, thiab waterproof txheej. Chemxin Hmoov-Hom Hom molecular sieve feem ntau siv nyob rau hauv synthesis cov ntaub ntawv ua ntxiv rau dej tshem tawm thiab npuas tua. Thaum muaj lw noo noo lossis kua qaub rau hauv hydroxyl tivthaiv ntawm ob-feem polyurethanide, uas ua rau cov pa roj polyurethanide, ua rau muaj cov nplaum uas cuam tshuam rau cov khoom lag luam.
Chemxin ua haujlwm molecular sab cib hmoov yog ib hom ntawm silicoaluminate crystalline cov khoom nrog cov khoom adsorption. Lawv tuaj yeem adsorb dej molecules thiab roj molecules, zoo tshem tawm cov kab noo thiab lwm yam me me molecular impurities, tiv thaiv npuas tsim.
Nyob rau hauv cov ntaub ntawv thov ntawm ob-tiv thaiv polyurethane nplaum nplaum, txawm tias muaj cov txheej txheem ua haujlwm, lossis qhib cov txheej txheem sib txawv tom qab sib txuas Cheebtsam A thiab B yuav tsum muaj. Qhov no tshwj xeeb tshaj yog rau cov khoom nrov xws li txhuas honeycomb panels, purification boards, thiab xuas tes ua polyrea cov khoom. Cov neeg ua haujlwm feem ntau muaj qhov xav tau zoo rau lub sijhawm qhib lub sijhawm ua haujlwm cov nplaum. Txawm li cas los xij, kev ua haujlwm zoo molecular sieve hmoov khoom tuaj yeem tso tawm thaum tshav kub kub, thiab raws li qhov kub tawm, ntsuas cov tshuaj tiv thaiv ntawm cov cheeb tsam a thiab b nrawm, yog li ua rau lub sijhawm qhib kom qhuav.
Txhawm rau kom tau raws li cov ntawv thov tiag tiag xav tau ntawm cov neeg siv khoom, Guangzhou Chemxin ib puag ncig cov ntaub ntawv Co., Ltd. tau tsim cov khoom siv molecular. Cov khoom no khaws cov txiaj ntsig zoo tshaj tawm thaum ua kom cov tshuaj tiv thaiv qeeb ntawm cov tshuaj tiv thaiv A thiab B, yog li ncua lub sijhawm qhib lub sijhawm. Nws tau pom dav dav los ntawm cov neeg siv khoom rau nws cov kev ua tau zoo thiab tam sim no stably muab.
