Polyurethane Tsuag HCFC-R141B Siv Prouduce Urethane Ua Npuas Ncauj

Cov khoom: Dichlorofluoroethane (HCFC-141B) yog tshuaj tsis muaj tshuaj lom thiab tsis muaj kab mob uas muaj ODP tus nqi tsawg thiab cov tshuaj muaj zog zoo heev. Vim nws lub cev thiab tshuaj muaj zog zoo li cov CFC-11 thiab CFC-113, nws muaj peev xwm hloov CFC-11 ua tus neeg ua npuas ntau rau tus npuas tawv los yog muag PU, los yog nws yuav hloov tau rau CFC-113 li hlau nqus thiab kab laug sab laug zoo li, nws yog ib qho thoob ntiaj teb lees paub CFCs hloov.

Daim ntawv thov:

1)        Siv raws li tus neeg saib kev ua tus foaming rau polyurethane tsuag

2)        Siv rau polyurethane ua npuas ncauj

3)        Siv los tsim cov ua npuas ncauj

4)        Siv rau expanding polyurethane ua npuas ncauj

P ackage and Storage: Packed nyob rau hauv hlau nruas, Nws yuav tsum tau muab cia rau hauv txias, qhuav thiab ventilated qhov chaw, thiab khaws cia deb ntawm tshav ntuj thiab los nag.

Yam ntxwv:

1. Kev Ruaj Ntseg: Nws tuaj yeem muab rau hauv qhov kub thiab txias tsis muaj kev hloov kho.

2.Cov dej: Txawm yog khib nyiab, nws tsis corrode hlau, stainless hlau, tooj liab. Tooj dag, txhuas thiab zine lwm yam

3. Solubility: Nws yog cov tshuaj nyob rau hauv feem ntau cov organic solvents, cawv thiab ether, nws muaj kev sib luag zoo heev nrog roj thiab roj nplua nyeem, tsis muaj cuab yeej hauv cov teebmeem rau feem ntau cov polymers xws li yas thiab cov kab xo.

4. Kev Taw Qhia: Cov kev sim tshuaj lom lub thoob ntiaj teb kev sib tw PATT II qhia tau hais tias nws muaj kev cuam tshuam rau ntawm tib neeg tej tawv nqaij thiab lub qhov muag, tab sis kev nqus cov HCFC-141B siab yuav ua rau muaj cov tshuaj loog
