HEMC yegiredhi rekuvaka

HEMC yegiredhi rekuvakaHydroxyethylMethylCelliloseinozivikanwa seMethyl Hydroxyethyl Cellulose (MHEC), iyoupfu huchena kana kuti hwakachena, hahunhuhwi uye hahuna kunaka, hunonyungudukaMumvura inopisa nemumvura inotonhora. HEMC yemhando yekuvaka inogona kuvaInoshandiswa se simende, gypsum, lime gelling agent, uye inochengetedza mvura, imusanganiswa wakanaka wezvinhu zvekuvaka upfu.

AZvimwe zvinhu: hydroxyethyl methyl cellulose; hydroxyethyl methyl cellulose; hydroxyethyl ethyl cellulose; 2-hydroxyethyl methyl ether cellulose, Methylhydroxyethylcellulose; Cellulose; 2-hydroxyethyl methyl ether; HEMC;

Hydroymethylmethylecellulose; hydroxyethylmethylcellulose; hydroxymethylethylcellulose.

Kunyoreswa kweCAS: 9032-42-2

Maumbirwo eMorekuru:

Zvimiro zveChigadzirwa:

1. Chitarisiko: HEMC ipfu chena kana kuti inenge chena; haina hwema uye haina kunaka.

2. Kunyungudika: Rudzi rweH muHEMC runogona kunyungudika mumvura iri pasi pe60℃, uye rudzi rweL runogona kunyungudika mumvura inotonhora chete. HEMC yakafanana neHPMC uye hainyungudike muzvinhu zvakawanda zvinonyungudika. Mushure mekugadzirisa pamusoro, HEMC inopararira mumvura inotonhora isina kuungana uye inonyungudika zvishoma nezvishoma, asi inogona kunyungudika nekukurumidza nekugadzirisa kukosha kwayo kwePH kusvika pa8-10.

3. Kugadzikana kwePH: Kuyerera kwemvura hakuchinji zvakanyanya mukati me2-12, uye kuyerera kwemvura kunoderera kupfuura huwandu uhu.

4. Kupfava: mwero wekupasa we80 mesh ndeye 100%; mwero wekupasa we100 mesh ndeye ≥99.5%.

5. Simba remagetsi renhema: 0.27-0.60g/cm3.

6. Tembiricha yekuora iri pamusoro pe200℃, uye inotanga kutsva pa360℃.

7. HEMC ine kukora kwakakosha, kugadzikana kwekumisikidzwa, kupararira, kubatana, kuumbwa, kuchengetwa kwemvura nezvimwe zvinhu.

8. Nekuti chigadzirwa ichi chine hydroxyethyl group, tembiricha yegel yechigadzirwa ichi inosvika 60-90℃. Pamusoro pezvo, hydroxyethyl group ine hydrophilicity yakakwira, izvo zvinoitawo kuti chiyero chekubatanidzwa kwechigadzirwa chive chakanaka. Kunyanya mukugadzirwa kwekupisa uye tembiricha yakakwira muzhizha, HEMC ine kuchengetedzwa kwemvura kwakakwira kupfuura methyl cellulose ine viscosity imwechete, uye mwero wekuchengetedzwa kwemvura hausi pasi pe85%.

Kukosha

Sechinhu chinoshanda pamusoro, hydroxyethyl methyl cellulose HEMC ine hunhu hunotevera pamusoro pekukora, kumisa, kubatanidza, emulsifying, kugadzira firimu, kuparadzira, kuchengetedza mvura uye kupa ma colloids anodzivirira:

(1) Hydroxyethyl methyl cellulose HEMC inonyungudika mumvura inopisa kana inotonhora, zvichiita kuti ive nemhando dzakasiyana-siyana dzekunyungudika uye hunhu hwekunakisa, kureva kuti, gelation isingapisi;

(2) Hydroxyethyl methyl cellulose HEMC inogona kushanda pamwe chete nemamwe mapolymers anonyungudika mumvura, masurfactants, uye munyu, uye inokora zvakanaka kwazvo kune mhinduro dze electrolyte dzine huwandu hwakawanda;

(3) HEMC ine simba rekuchengetedza mvura kupfuura methyl cellulose, uye kugadzikana kwayo kwekupenya, kupararira, uye kuramba kwayo kuonda kwakasimba kupfuura hydroxyethyl cellulose.

Nzira yekugadzirira mhinduro

(1) Wedzera huwandu hwakatarwa hwemvura yakachena mumudziyo;

(2) Wedzera hydroxyethyl methyl cellulose HEMC uchikurunga zvishoma nezvishoma, wokurunga kusvika hydroxyethyl methyl cellulose yese yanyungudika zvakaenzana;

(3) Tichifunga nezve data redu rekuyedza tekinoroji, zvinokurudzirwa zvikuru kuiwedzera mushure mekunge polymer emulsion yawedzerwa (kureva, hydroxyethyl methyl cellulose).HEMCyakasanganiswa kare ne ethylene glycol kana propylene glycol).
