Kedu ihe dị iche n'etiti HPMC na Mhec?

Hydroxypyl Methylcelllose (HPMC) na methyyddythythythythythythythythythyythyyth bụ mkpụrụ osisi cellulose na-eji n'ọtụtụ ụlọ ọrụ n'ihi ihe ndị dị iche iche. Ọ bụ ezie na ha nwere myirịta, ha na-egosipụtakwa ọdịiche dị mkpa.

Hydroxypylththth methylcellose (hpmc):

1.CHEMICAL:
HPMC bụ polymer polymer sitere na cellose.
Ọ mejuputara nkeji nke ashydrogluse jikọtara ọnụ na hydroxyl na otu methoxy.

2. Arụmọrụ:
Mmiri solubility: HPMC na-agbanye mmiri na mmiri, yabụ na-ejikwa ọtụtụ usoro.
Fim na-etolite: Ọ nwere ike mepụta ihe nkiri, na-eme ya dị mma maka ngwa chọrọ mkpuchi nchebe.
Igwe ọkụ na-anyụ: nwee akụrụngwa na-enwu ọkụ, nke nwere ike ịba uru na ngwa ụfọdụ.

3. Ngwa:
Ọgwụ ọgwụ: Ejiri ya dị ka ndị na-eme ọgwụ, ihe nkiri a na-ese ihe na mwepụ matrik na mbadamba ọgwụ.
Industrylọ ọrụ owuwu: Ejiri ya na adle times nke sitere na time, nkupu gypsum na nke ileghara onwe ya anya.
Industrylọ ọrụ nri: Ejiri dị ka nke na-eto eto ma sie nri.

4. Mmepụta:
A na-emepụta site na ogo nke cellose na propylene oxide na methyl chloride.
Ogo nke dochie anya (DS) na-ekpebi oke nke hydroxyl na otu methoxy.

Methyddydydydyylcelllose (Mhec):

1.CHEMICAL:
Mhec bụkwa onye na-ahụ maka mkpụrụ osisi celdrolose na hydroxyethyl na otu metoxy òtù na Methoxy jikọtara na Backbose Backbone.

2. Arụmọrụ:
Mmiri solubility: Dị ka HPMC, Mhec bụ mmiri soluble, nke na-atụnye ụtụ na nkọwa dị iche iche.
Egosiputa mmiri na mmiri dị mma: Mhec n'ozuzu na-egosipụta njigide mmiri ka mma karịa hpmc.

3. Ngwa:
Industrylọ ọrụ owuwu: Site na ebe a na-ahụ maka ihe ndị na-eme mkpọtụ maka nkụchi nke ciment, taịlị na ngwaahịa na ngwaahịa gypsum.
Eserese na mkpuchi: Ọrụ dị ka Rhiology Modeifier na eserese nke ihe ndị dabeere na mkpuchi mmiri.
Ọgwụ ọgwụ: Ejiri ya maka njikwa ọgwụ na-enye ọgwụ.

4. Mmepụta:
Mepụtara site na ogo nke cellose na methych chloride na ethyl chloride.
Ogo nke dochie Njirimara na arụmọrụ nke Mhecs.

Ọdịiche dị n'etiti HPMC na Mhec:

1. Usoro etherification:
HPMC bụ Synledy site na iji usoro propylene na methyl chloride.
A na - emepụta Mhec site na iji Metyl chloride na ethyl chloride.

2. Njide mmiri:
Mhec n'ozuzu na-egosipụta ihe dị mma na-eme ka njikọta dị mma karịa hpmc.

3. Ngwa:
Ọ bụ ezie na enwere ụfọdụ mmachi, ngwa a kapịrị ọnụ nwere ike meere otu ihe dabere na ụdị ndị ọzọ dabere na agwa ya pụrụ iche.

4. Ọkpụkpụ ikuku:
HPMC na-egosiputa ahihia ihe eji eme ihe, ebe mhec nwere ike inwe agwa rhicals di iche.

HPMC na Mhec nwere ọtụtụ ngwa na ụlọ ọrụ dị iche iche, nke ọ bụla nwere uru pụrụ iche. Nhọrọ dị n'etiti ha na-adabere na ngwa a kapịrị ọnụ na arụmọrụ achọrọ. Ma na ọgwụ na-ere ọgwụ, iwu owuwu ma ọ bụ ubi ndị ọzọ, nghọta ndị ọzọ na-enyere aka ịme mkpebi dị mma na usoro na usoro dị iche iche.
