Chiyambi cha malonda ndi zinthu zake

N-hydroxymethylacrylamide ndi ufa woyera wa kristalo. Kuchuluka kwake ndi 1.185 (23/4 ℃), ndipo malo osungunuka ndi 75 ℃. Mu solvent ya hydrophilic imathanso kusungunuka, chifukwa cha mafuta acid esters, acrylic acid ndi methylacrylate, kutentha kumakhala ndi kusungunuka kwakukulu, koma sikusungunuka kwambiri mu solvents ya hydrophobic monga ma hydrocarbons, ma halogenated hydrocarbons. Ingagwiritsidwe ntchito ngati cross-linking agent, imagwiritsidwa ntchito kwambiri mu fiber modified resin, processing dye, plastic binder, soil stabilizer, ndi zina zotero. Molekyulu ya chinthucho ili ndi mgwirizano wawiri wolumikizidwa ndi carbonyl group ndi reactive hydroxyl methyl group. Ndi crosslinking monomer yomwe imagwiritsidwa ntchito kwambiri pakusintha ulusi, kukonza resin, zomatira, mapepala, chikopa, chitsulo pamwamba pa chitsulo, ndipo ingagwiritsidwenso ntchito ngati dothi lokonzanso.

gwiritsani ntchito

Ndi chinthu chopangira utomoni wotentha, utoto wopepuka wa epoxy resin, utoto wosagwira mafuta komanso utoto wouma. Emulsion yake ya copolymerization imagwiritsidwa ntchito pomaliza ulusi, nsalu, chikopa ndi pepala. Imagwiritsidwanso ntchito ngati guluu wamatabwa, chitsulo, ndi zina zotero.
Amagwiritsidwa ntchito ngati monomer yolumikizidwa ndi mtanda pa emulsion ya acrylic. Mlingo wa guluu wogwirizana ndi kuthamanga kwa acrylic emulsion wokhala ndi gulu la carboxyl ndi L% ~ 2% ya kulemera konse kwa monomer, ngati kuli kopitilira 3%, kukhuthala koyamba kudzachepa kwambiri. Pa guluu wolumikizana ndi emulsion wopanda gulu la carboxyl, mlingo wamba supitirira 5%. Kutentha kwa MMAM crosslinking reaction kokha ndikokwera, nthawi zambiri 120 ~ 170℃, kuwonjezera chothandizira cha proton kungachepetse kutentha kwa crosslinking. Acrylic acid (AA) ikhoza kupereka ma hydrogen proton, komanso copolymerization ndi acrylate, kotero MMAM kuti ipange wothandizira wolumikizana ndi AA, kuchuluka kwa 3:2 ndikobwino. Cross-linker HA ikhoza kulowa m'malo mwa N-hydroxymethylacrylamide ndipo ilibe formaldehyde.

phukusi ndi mayendedwe

B. Chogulitsachi chingagwiritsidwe ntchito, 25KG, matumba
C. Sungani yotsekedwa m'nyumba pamalo ozizira, ouma komanso opumira mpweya. Zidebe ziyenera kutsekedwa bwino mukatha kugwiritsa ntchito nthawi iliyonse musanagwiritse ntchito.
D. Chogulitsachi chiyenera kutsekedwa bwino panthawi yonyamula kuti chisasakanikirane ndi chinyezi, alkali ndi asidi wamphamvu, mvula ndi zinyalala zina.
