Chiyambi cha malonda ndi zinthu zake
Acrylamide ili ndi gulu la carbon-carbon double bond ndi amide, yokhala ndi double bond chemistry: pansi pa ultraviolet irradiation kapena kutentha kwa melting point, polymerization yosavuta; Kuphatikiza apo, double bond ikhoza kuwonjezeredwa ku hydroxyl compound pansi pa alkaline mikhalidwe kuti ipange ether; Ikawonjezeredwa ndi primary amine, monadic adder kapena binary adder imatha kupangidwa. Ikawonjezeredwa ndi secondary amine, monadic adder imatha kupangidwa. Ikawonjezeredwa ndi tertiary amine, quaternary ammonium salt imatha kupangidwa. Ndi activated ketone added, kuwonjezerako kumatha kusinthidwa nthawi yomweyo kuti apange lactam. Ikhozanso kuwonjezeredwa ndi sodium sulfite, sodium bisulfite, hydrogen chloride, hydrogen bromide ndi mankhwala ena osapangidwa; Chogulitsachi chingathenso kupangidwanso, monga ndi ma acrylates ena, styrene, halogenated ethylene copolymerization; Double bond ingachepetsedwenso ndi borohydride, nickel boride, carbonyl rhodium ndi ma catalysts ena kuti apange propanamide; Kusungunuka kwa osmium tetroxide kungapangitse diol. Gulu la amide la mankhwalawa lili ndi kufanana kwa mankhwala a aliphatic amide: limakumana ndi sulfuric acid kupanga mchere; Pakakhala chothandizira cha alkaline, hydrolysis ku acrylic acid root ion; Pakakhala chothandizira cha acid, hydrolysis ku acrylic acid; Pakakhala chothandizira chothetsa madzi m'thupi, kutaya madzi m'thupi ku acrylonitrile; Limakumana ndi formaldehyde kupanga N-hydroxymethylacrylamide.
gwiritsani ntchito
Acrylamide ndi imodzi mwa zinthu zofunika kwambiri komanso zosavuta kwambiri pa mndandanda wa acrylamide. Imagwiritsidwa ntchito kwambiri ngati zinthu zopangira organic synthesis ndi polymer. Polima imasungunuka m'madzi, kotero imagwiritsidwa ntchito kupanga flocculant yochizira madzi, makamaka poyambitsa flocculation ya mapuloteni ndi wowuma m'madzi. Kuphatikiza pa flocculation, pali kukhuthala, kukana kudulidwa, kuchepetsa kukana, kufalikira ndi zina zabwino kwambiri. Ikagwiritsidwa ntchito ngati kusintha kwa nthaka, imatha kuwonjezera kulowa kwa madzi ndi kusunga chinyezi m'nthaka; Imagwiritsidwa ntchito ngati chowonjezera chodzaza mapepala, imatha kuwonjezera mphamvu ya pepala, m'malo mwa wowuma, utomoni wa ammonia wosungunuka m'madzi; Imagwiritsidwa ntchito ngati chothandizira cha mankhwala, imagwiritsidwa ntchito pofukula ngalande zapamadzi, kuboola zitsime zamafuta, migodi ndi madamu; Imagwiritsidwa ntchito ngati chosinthira ulusi, imatha kusintha mawonekedwe akuthupi a ulusi wopangidwa; Imagwiritsidwa ntchito ngati chosungira, ingagwiritsidwe ntchito pazinthu zapansi panthaka zotsutsana ndi dzimbiri; Ingagwiritsidwenso ntchito pazowonjezera zamakampani azakudya, chosungunula utoto, chosindikizira ndi chopaka utoto. Ndi yankho la phenolic resin, imatha kupangidwa kukhala guluu wagalasi, ndipo rabara pamodzi imatha kupangidwa kukhala guluu womvera kupsinjika. Zipangizo zambiri zopangidwa zimatha kukonzedwa pogwiritsa ntchito polymerization ndi vinyl acetate, styrene, vinyl chloride, acrylonitrile ndi ma monomers ena. Chogulitsachi chingagwiritsidwenso ntchito ngati mankhwala, mankhwala ophera tizilombo, utoto, ndi utoto wa zipangizo zopangira.
phukusi ndi mayendedwe
B. Chogulitsachi chingagwiritsidwe ntchito, matumba a 20KG.
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.
