Kwiyandikisha muri CAS: 9032-42-2

Imiterere ya Molekile:

Ibiranga Ibicuruzwa:

1. Ishusho: HEMC ni ifu y'umweru cyangwa hafi y'umweru; nta mpumuro cyangwa uburyohe.

2. Gushonga: Ubwoko bwa H muri HEMC bushobora gushonga mu mazi ari munsi ya 60°C, naho ubwoko bwa L bushobora gushonga mu mazi akonje gusa. HEMC ni kimwe na HPMC kandi ntishobora gushonga mu bintu byinshi bivangwa n’ibinyabuzima. Nyuma yo gutunganya ubuso, HEMC ikwirakwira mu mazi akonje idateranyije kandi ishonga buhoro buhoro, ariko ishobora gushonga vuba iyo ihinduye agaciro kayo ka PH kuri 8-10.

3. Guhagarara kw'agaciro ka PH: Ubushobozi bwo gupima ikirere buhinduka gato mu rugero ruri hagati ya 2 na 12, kandi ubushobozi bwo gupima ikirere bugabanuka birenze urwo rugero.

4. Uburemere: igipimo cyo gutsinda cya mesh 80 ni 100%; igipimo cyo gutsinda cya mesh 100 ni ≥99.5%.

5. Uburemere bw'impimbano: 0.27-0.60g/cm3.

6. Ubushyuhe bwo kubora buri hejuru ya 200°C, kandi butangira gushya kuri 360°C.

7. HEMC ifite ubunini bugaragara, ihamye, ikwirakwira, ifatanye, irahindagurika, amazi agumana n'ibindi biranga.

8. Kubera ko iki gicuruzwa kirimo itsinda rya hydroxyethyl, ubushyuhe bwa gel bw'iki gicuruzwa bugera kuri 60-90°C. Byongeye kandi, itsinda rya hydroxyethyl rifite ubushobozi bwo kuvura amazi menshi, bigatuma igipimo cyo guhuza iki gicuruzwa kiba cyiza. Cyane cyane mu gihe cy'ubushyuhe n'ubushyuhe bwinshi mu mpeshyi, HEMC ifite ubushobozi bwo kubika amazi menshi kurusha methyl cellulose ifite ubushyuhe bumwe, kandi igipimo cyo kubika amazi ntabwo kiri munsi ya 85%.

Icyiciro cy'ibicuruzwa

Akamaro

Nk'ikintu gikora ku buso, hydroxyethyl methyl cellulose HEMC ifite ibi bikurikira usibye gukomera, guhagarika, guhuza, guhuza, gukora filime, gutatanya, kubika amazi no gutanga colloids zirinda:

(1) Hydroxyethyl methyl cellulose HEMC irashongeshwa mu mazi ashyushye cyangwa akonje, bigatuma igira imiterere itandukanye yo gushonga no gushonga, ni ukuvuga ihindagurika ritari iryo mu bushyuhe;

(2) Hydroxyethyl methyl cellulose HEMC ishobora kubana n'izindi polymer nyinshi zishobora gushonga mu mazi, surfactants, n'umunyu, kandi ni umuti mwiza wo gukurura electrolyte nyinshi;

(3) HEMC ifite ubushobozi bwo kubika amazi kurusha selulose ya methyl, kandi ubushobozi bwayo bwo gushonga, gukwirakwira kwayo, no kurwanya indwara ya mildew birakomeye kurusha selulose ya hydroxyethyl.

Uburyo bwo gutegura umuti

(1) Shyiramo amazi meza mu gikoresho runaka;

(2) Shyiramo hydroxyethyl methyl cellulose HEMC munsi yo gukangura vuba, hanyuma uvange kugeza igihe hydroxyethyl methyl cellulose yose ishongeshejwe neza;

(3) Dukurikije amakuru y’ibizamini byacu bya tekiniki, turasaba cyane kubishyiramo nyuma yo kongeramo emulsion ya polymer (ni ukuvuga hydroxyethyl methyl cellulose).HEMCivanzwe mbere na ethylene glycol cyangwa propylene glycol).

Usimyaka

Mu ngandainyubakoibikoresho,HEMC yo mu rwego rw'ubwubatsibirakwiriyekole y'amatafari, sima, sima yumye ivanze, kwipima, sima ya gypsum,irangi rya latex, ibikoresho byo kubaka, ibindi bikorwa by'ubwubatsi, gucukura peteroli, ibikoresho byo kwita ku buzima bwite, ibikoresho byo gusukura, nibindi, bikoreshwa muri rusange nk'ibikomeza, ibikoresho birinda, kole, ibikomeza, n'ibindi bihagarika bishobora kandi gukoreshwa nk'amajeli akunda amazi, ibikoresho bya matrix, gutegura ibikoresho byo gusohora ibintu bihoraho, kandi bishobora no gukoreshwa nk'ibikomeza mu biribwa, nibindi.

Pgufunga n'ububiko

(1) Bipakiye mu gikapu cya polyethylene cyangwa mu gikapu cy’impapuro, 25KG/igikapu;

(2) Gumisha umwuka utemba ahantu habikwa, kwirinda izuba ryinshi, kandi ubirinde ahantu hashobora gutwikirwa n'inkongi z'umuriro;

(3) Kubera ko hydroxyethyl methyl cellulose HEMC ari hygroscopic, ntigomba gushyirwa mu kirere. Ibikoresho bitakoreshejwe bigomba gufungwa no kubikwa, kandi birindwe ubushuhe.
