Ma synonyms mu Chingerezi
N -m, ham, n-ma
Katundu wa mankhwala
Cas: 924-5-5 Einecs: 213-103-2 Kapangidwe: Ch2 = Chinconchinyezi
Njira ya molecular: C4H7NE2 Kusungunuka: 74-75 ℃
Kuchulukitsa: 1.074
Madzi osungunuka: <0.1g / 100 ml pa 20.5 ℃
Kuyambitsa Zoyambitsa ndi Zinthu
N-Hydroxymethlamide ndi ufa woyera wa crystalline. Kuchulukitsa kwachibale ndi 1.185 (23/4 ℃), ndipo malo osungunuka ndi 75 ℃. Mu hydrophilic solvel amathanso kusungunuka, kwa mafuta a acid etter, acrylic acid ndi methlacrytet, kutentha kumasungunuka, koma pafupifupi ma hydrocarbons, hydrocarbons. Itha kugwiritsidwa ntchito ngati wothandizira wolumikizirana wolumikizira, wogwiritsidwa ntchito kwambiri wosinthika, kukonza utoto wa pulasitiki, dothi lopangidwa ndi ma carbonyl meth meth. Ndiwo motomer yolumikizidwa kwambiri yomwe imagwiritsidwa ntchito kwambiri yosinthira, zomata, mapepala, zikopa, zikopa, zikopa, ndipo imathanso kugwiritsidwa ntchito ngati dothi.
gwilitsa nchito
Ndi zinthu zosaphika zopanga thermoseting stun, kuwala kwa epoxy onetsetsani zokutira, zokutidwa ndi mafuta komanso zouma. Emulsirization yake emulsion imagwiritsidwa ntchito ngati chitsenthedwe, nsalu, chikopa ndi zokutira pepala. Amagwiritsidwanso ntchito ngati chomatira nkhuni, chitsulo, ndi zina.
Chogwiritsidwa ntchito ngati monomer wolumikizidwa wa acrylic emulsion. Mlingo wa acrylic emulsion kukakamiza zomatira ndi gulu la carboxyl ndi l% ~ 2% ya monomer misa, ngati ma vispor oyambilira adzachepetsedwa kwambiri. Kwa emulsion yomatira popanda gulu la carboxyl, Mlingo waukulu si wopitilira 5%. Mmam Crosslinking Kutalika Kwawokha Kumakula, nthawi zambiri 120 ~ 170 ~ Kuchulukitsa Carton-Traptorst Kuchepetsa kutentha. Acrylic acid (AA) imatha kupereka mapulogalamu a hydrojeni, ndipo popsolymerization ndi acrylate, kotero mmam kuti apange wothandizira 3: 2 ndibwino. Mtanda-Linker ha amatha kusinthanitsa ndi n-hydroxymethylacrylamide ndipo alibe formaldehyde.
phukusi ndi mayendedwe
B. Izi zitha kugwiritsidwa ntchito, 25kg, matumba
C. Malo osindikizidwa pamalo ozizira komanso owuma komanso mpweya m'nyumba. Zotengera ziyenera kusindikizidwa mwamphamvu pambuyo pakugwiritsa ntchito iliyonse musanagwiritse ntchito.
D. Izi ziyenera kusindikizidwa bwino nthawi yoyendera kuteteza chinyezi, champhamvu chalkali ndi asidi, mvula ndi zina zosakanikirana.
