HEMC yomanga

HEMC yomangaHydroxyethylMethylCelliloseimadziwika kuti Methyl Hydroxyethyl Cellulose (MHEC), ndipondi ufa woyera kapena wosayera, wopanda fungo komanso wopanda kukoma, wosungunukaMu madzi otentha komanso ozizira. HEMC ya kalasi yomanga ikhoza kukhalaAmagwiritsidwa ntchito ngati simenti, gypsum, laimu gelling agent, chothandizira kusunga madzi, ndi chinthu chabwino kwambiri chosakaniza zipangizo zomangira ufa.

Kapangidwe ka Mamolekyu:

Zinthu Zogulitsa:

1. Maonekedwe: HEMC ndi ufa woyera kapena pafupifupi woyera; wopanda fungo komanso wopanda kukoma.

2. Kusungunuka: Mtundu wa H mu HEMC ukhoza kusungunuka m'madzi osakwana 60℃, ndipo mtundu wa L ukhoza kusungunuka m'madzi ozizira okha. HEMC ndi yofanana ndi HPMC ndipo sisungunuka m'zinthu zambiri zachilengedwe. Pambuyo pokonza pamwamba, HEMC imafalikira m'madzi ozizira popanda kusonkhana ndipo imasungunuka pang'onopang'ono, koma imatha kusungunuka mwachangu posintha PH yake kukhala 8-10.

3. Kukhazikika kwa PH: Kukhuthala kwa viscosity sikusintha kwenikweni mkati mwa 2-12, ndipo kukhuthala kwa viscosity kumachepa kupitirira mtunda uwu.

4. Kusalala: kuchuluka kwa maukonde 80 ndi 100%; kuchuluka kwa maukonde 100 ndi ≥99.5%.

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

6. Kutentha kwa kuonda kumakhala kopitirira 200℃, ndipo kumayamba kuyaka pa 360℃.

7. HEMC ili ndi kukhuthala kwakukulu, kukhazikika kwa kuyimitsidwa, kufalikira, kugwirizana, kupangika, kusunga madzi ndi zina.

8. Popeza mankhwalawa ali ndi gulu la hydroxyethyl, kutentha kwa gel kwa mankhwalawa kumafika pa 60-90℃. Kuphatikiza apo, gulu la hydroxyethyl lili ndi hydrophilicity yambiri, zomwe zimapangitsanso kuti chiŵerengero cha zinthuzo chikhale chabwino. Makamaka m'nyengo yotentha komanso yotentha kwambiri m'chilimwe, HEMC imakhala ndi madzi ambiri kuposa methyl cellulose ya viscosity yomweyo, ndipo chiŵerengero cha madzi sichichepera 85%.

Kalasi ya Zamalonda

Kufunika

Monga chothandizira pamwamba, hydroxyethyl methyl cellulose HEMC ili ndi makhalidwe otsatirawa kuwonjezera pa kukhuthala, kuyimitsa, kugwirizana, kusakaniza, kupanga filimu, kufalitsa, kusunga madzi ndi kupereka ma colloids oteteza:

(1) Hydroxyethyl methyl cellulose HEMC imasungunuka m'madzi otentha kapena ozizira, zomwe zimapangitsa kuti ikhale ndi mitundu yosiyanasiyana ya kusungunuka ndi kukhuthala, ndiko kuti, gelation yosatentha;

(2) Hydroxyethyl methyl cellulose HEMC ikhoza kukhala pamodzi ndi ma polima ena ambiri osungunuka m'madzi, ma surfactants, ndi mchere, ndipo ndi chokhuthala chabwino kwambiri cha mayankho a electrolyte okhala ndi kuchuluka kwakukulu;

(3) HEMC imasunga madzi mwamphamvu kuposa methyl cellulose, ndipo kukhazikika kwake mu viscosity, dispersibility, ndi mildew ndi zamphamvu kuposa hydroxyethyl cellulose.

Njira yokonzekera yankho

(1) Onjezani madzi oyera okwanira mu chidebecho;

(2) Onjezani hydroxyethyl methyl cellulose HEMC pansi pa kusakaniza kwachangu, ndikusakaniza mpaka hydroxyethyl methyl cellulose yonse isungunuke mofanana;

(3) Poganizira deta yathu yoyesera zaukadaulo, tikulimbikitsa kwambiri kuiwonjezera pambuyo poti polymer emulsion yawonjezedwa (monga hydroxyethyl methyl cellulose).HEMCimasakanizidwa kale ndi ethylene glycol kapena propylene glycol).

Uszaka

Mu mafakitalenyumbazipangizo,HEMC ya kalasi yomangandi yoyenerazomatira za matailosi, ma plaster a simenti, matope osakaniza owuma, kudzilinganiza, plaster ya gypsum,Utoto wa latex, zomangira zinthu zomangira, minda ina yomangira, kuboola malo ophikira mafuta, zinthu zosamalira thupi, zotsukira, ndi zina zotero, zomwe nthawi zambiri zimagwiritsidwa ntchito ngati zothira, zoteteza, zomatira, zokhazikika, ndi zomangira. Zingagwiritsidwenso ntchito ngati ma gels ophikira madzi, zipangizo za matrix, kukonzekera zokonzekera zotulutsa zinthu zamtundu wa matrix, komanso zingagwiritsidwenso ntchito ngati zokhazikika muzakudya, ndi zina zotero.

Pkutsekeka ndi malo osungira

(1) Yodzaza mu thumba la polyethylene kapena thumba la pepala lopangidwa ndi pulasitiki, 25KG/thumba;

(2) Sungani mpweya ukuyenda m'malo osungiramo zinthu, pewani kuwala kwa dzuwa mwachindunji, ndipo sungani kutali ndi zinthu zoyaka moto;

(3) Popeza hydroxyethyl methyl cellulose HEMC ndi yosalala, siyenera kuyikidwa mumlengalenga. Zinthu zosagwiritsidwa ntchito ziyenera kutsekedwa ndikusungidwa, ndikutetezedwa ku chinyezi.
