Ntchito yomanga HEMC

Ntchito yomanga HEMCHydroxyethylMethylCelluloseamadziwika kuti Methyl Hydroxyethyl Cellulose(MHEC), izondi ufa woyera kapena wopanda fungo, wopanda fungo, wosakoma, wosungunukaM'madzi onse otentha ndi ozizira. Ntchito yomanga HEMC ikhoza kukhalaAmagwiritsidwa ntchito ngati simenti, gypsum, laimu gelling agent, water retention wothandizila, ndi kusakanizikana kwabwino kwa zida zomangira ufa.

Amankhwala: hydroxyethyl methyl cellulose; hydroxyethyl methyl cellulose; hydroxymethyl ethyl cellulose; 2-hydroxyethyl methyl ether cellulose, methylhydroxyethyl cellulose; Ma cellulose; 2-hydroxyethyl methyl ether; HEMC;

Hydroymethylmethylecellulose; hydroxyethyl methyl cellulose; hydroxymethyl ethyl cellulose.

Kulembetsa kwa CAS: 9032-42-2

Kapangidwe ka Molecular:

Zogulitsa:

1. Maonekedwe: HEMC ndi yoyera kapena pafupifupi ufa woyera; zopanda fungo komanso zosakoma.

2. Kusungunuka: Mtundu wa H mu HEMC ukhoza kusungunuka m'madzi pansi pa 60 ℃, ndipo mtundu wa L ukhoza kusungunuka m'madzi ozizira. HEMC ndi yofanana ndi HPMC ndipo sisungunuka mu zosungunulira zambiri za organic. Pambuyo pa chithandizo chapamwamba, HEMC imabalalika m'madzi ozizira popanda agglomeration ndikusungunula pang'onopang'ono, koma imatha kusungunuka mwamsanga mwa kusintha mtengo wake wa PH kukhala 8-10.

3. Kukhazikika kwa mtengo wa PH: Kuwoneka kwa viscosity kumasintha pang'ono mkati mwa 2-12, ndipo kukhuthala kumachepetsedwa kupitirira izi.

4. Fineness: kuchuluka kwa ma mesh 80 ndi 100%; kuchuluka kwa 100 mesh ndi ≥99.5%.

5. Mphamvu yokoka yabodza: ​​0.27-0.60g / cm3.

6. Kutentha kwa kutentha kumakhala pamwamba pa 200 ℃, ndipo kumayamba kutentha pa 360 ℃.

7. HEMC ili ndi kukhuthala kwakukulu, kukhazikika kwa kuyimitsidwa, kufalikira, kugwirizanitsa, kuumba, kusunga madzi ndi makhalidwe ena.

8. Chifukwa mankhwalawa ali ndi gulu la hydroxyethyl, kutentha kwa gel osakaniza kumafika 60-90 ℃. Kuphatikiza apo, gulu la hydroxyethyl lili ndi hydrophilicity yayikulu, yomwe imapangitsanso kuti mtengo wolumikizana ukhale wabwino. Makamaka pakumanga kotentha ndi kutentha kwambiri m'chilimwe, HEMC imakhala ndi madzi osungira madzi kuposa methyl cellulose ya viscosity yomweyi, ndipo madzi osungira madzi si osachepera 85%.

Kufunika

Monga chinthu chogwira ntchito pamwamba, hydroxyethyl methyl cellulose HEMC ili ndi zizindikiro zotsatirazi kuwonjezera pa kukhuthala, kuyimitsa, kumanga, kutsekemera, kupanga mafilimu, kufalitsa, kusunga madzi ndi kupereka ma colloids oteteza:

(1) Hydroxyethyl methyl cellulose HEMC imasungunuka m'madzi otentha kapena ozizira, ndikupangitsa kuti ikhale ndi mitundu yambiri ya solubility ndi viscosity, ndiko kuti, gelation yopanda kutentha;

(2) Hydroxyethyl methyl cellulose HEMC imatha kukhala limodzi ndi ma polima ena osungunuka m'madzi, ma surfactants, ndi mchere, ndipo ndi thickener yabwino kwambiri yothetsera ma electrolyte apamwamba kwambiri;

(3) HEMC ili ndi madzi osungira madzi amphamvu kuposa methyl cellulose, ndipo kukhazikika kwake kwa viscosity, dispersibility, ndi mildew kukana zimakhala zamphamvu kuposa za hydroxyethyl cellulose.

Njira yokonzekera yankho

(1) Onjezani kuchuluka kwa madzi oyera mumtsuko;

(2) Onjezani hydroxyethyl methyl cellulose HEMC pansi pa kusonkhezera pang'ono-liwiro, ndi kusonkhezera mpaka hydroxyethyl methyl cellulose itasungunuka mofanana;

(3) Potengera chidziwitso chathu chaukadaulo, tikulimbikitsidwa kuti tiwonjezere pambuyo powonjezera polima emulsion (ie, hydroxyethyl methyl cellulose).Mtengo HEMCimasakanizidwa kale ndi ethylene glycol kapena propylene glycol).

Uszaka

Mu mafakitalekumangazipangizo,Ntchito yomanga HEMCndi oyenerazomatira matailosi, pulasitala simenti, matope osakaniza owuma, kudziwongolera, pulasitala ya gypsum,utoto wa latex, zomangira zomangira, minda ina yomanga, kubowola mafuta, zinthu zosamalira anthu, zotsukira, ndi zina zambiri, zomwe zimagwiritsidwa ntchito ngati zokhuthala, zoteteza, zomatira, zomangira, zoyimitsa, ndi zoyimitsa zitha kugwiritsidwanso ntchito ngati ma gels a hydrophilic, matrix. , kukonzekera matrix-mtundu wokhazikika-kumasulidwa kukonzekera, ndipo angagwiritsidwenso ntchito ngati stabilizers mu zakudya, etc. zotsatira.

Packaging ndi kusunga

(1) ankanyamula mu pepala-pulasitiki gulu polyethylene thumba kapena thumba pepala, 25KG / thumba;

(2) Onetsetsani kuti mpweya ukuyenda m'malo osungiramo, pewani kuwala kwadzuwa, ndipo pewani kumagwero amoto;

(3) Chifukwa hydroxyethyl methyl cellulose HEMC ndi hygroscopic, siyenera kuwululidwa ndi mpweya. Zinthu zomwe sizinagwiritsidwe ntchito ziyenera kusindikizidwa ndikusungidwa, ndi kutetezedwa ku chinyezi.

20'FCL: 12Ton yokhala ndi palletized, 13.5Ton yopanda palletized.
