Chiyambi cha malonda ndi mawonekedwe ake

N-hydroxymethylacrylamide ndi ufa woyera wa crystalline.Kachulukidwe wachibale ndi 1.185(23/4 ℃), ndipo malo osungunuka ndi 75 ℃.Ambiri hydrophilic zosungunulira akhoza kusungunuka, chifukwa mafuta asidi esters, asidi akiliriki ndi methylacrylate, Kutentha alinso kwambiri solubility, koma pafupifupi insoluble mu solvents hydrophobic monga hydrocarbons, halogenated hydrocarbons.Angagwiritsidwe ntchito ngati wothandizira mtanda, chimagwiritsidwa ntchito CHIKWANGWANI kusinthidwa utomoni, processing utoto, pulasitiki binder, nthaka stabilizer, etc. The molekyulu ya mankhwala ali ndi awiri chomangira conjugated ndi carbonyl gulu ndi zotakasika hydroxyl methyl gulu.Ndi monoma yolumikizira kwambiri yomwe imagwiritsidwa ntchito kwambiri pakusintha utomoni, kukonza utomoni, zomatira, mapepala, zikopa, zitsulo zopangira mankhwala, ndipo zitha kugwiritsidwanso ntchito ngati kusintha kwa nthaka.

ntchito

Ndizinthu zopangira utomoni wa thermosetting, zokutira zopepuka za epoxy resin, zokutira zosagwirizana ndi mafuta ndi zokutira zouma.Emulsion yake copolymerization ntchito CHIKWANGWANI kumaliza, nsalu, zikopa ndi pepala ❖ kuyanika.Amagwiritsidwanso ntchito ngati zomatira matabwa, zitsulo, etc.
Amagwiritsidwa ntchito ngati cholumikizira cholumikizira mtanda cha acrylic emulsion.Mlingo wa akiliriki emulsion kuthamanga tcheru zomatira munali carboxyl gulu L % ~ 2% ya okwana monoma misa, ngati kuposa 3%, kukhuthala koyamba kudzakhala kuchepetsedwa kwambiri.Kwa zomatira za emulsion popanda gulu la carboxyl, mlingo wamba siwopitilira 5%.MMAM crosslinking anachita kutentha yekha ndi apamwamba, zambiri 120 ~ 170 ℃, kuwonjezera pulotoni chothandizira akhoza kuchepetsa kutentha crosslinking.Acrylic acid (AA) imatha kupereka ma protoni a haidrojeni, ndi copolymerization ndi acrylate, kotero MMAM kupanga gulu lophatikizana ndi AA, kuchuluka kwa 3: 2 kuli bwino.Cross-linker HA imatha kulowa m'malo mwa N-hydroxymethylacrylamide ndipo ilibe formaldehyde.

phukusi ndi transport

B. Izi angagwiritsidwe ntchito, 25KG, matumba
C. Sungani chosindikizidwa mu malo ozizira, owuma ndi mpweya wokwanira m'nyumba.Zotengera ziyenera kutsekedwa mwamphamvu mukatha kugwiritsa ntchito chilichonse musanagwiritse ntchito.
D. Mankhwalawa ayenera kusindikizidwa bwino panthawi yoyendetsa kuti ateteze chinyezi, alkali wamphamvu ndi asidi, mvula ndi zonyansa zina kuti zisasakanike.
