Ọrụ HPMC na ngwa agha

1.WE ngwa ngwa ngwakọta: ngwa agha a gwakọtara bụ ụdị ciment, ezigbo nchịkọta, na-agwa ya na ebe a na-ere ahịa, ma jiri ngwakọta a na-ere mmiri dị iche iche.

A na-eji ya na-eme ka mmiri na-edebe mmiri na-edebe mmiri 2.hydroxy. N'ihe banyere gypsum dị ka ihe mkpuchi iji melite ngwa na oge ọrụ dị egwu, njigide mmiri nke hpmc na-egbochi ike ịmịcha ngwa ngwa, ma na-eme ka ike gwụsịa. Njikwa mmiri bụ akụ dị mkpa nke hydropyylthylthyl methyl cellulose Hpmc, ọ bụkwa nchegbu nke ọtụtụ ndị na-emepụta ngwa ngwa mmiri. Ihe ndị metụtara njigide mmiri nke ngwa ikuku na-emetụta oke HPMC agbakwunyere, viscosise ahụ na ọnọdụ okpomọkụ nke ojiji.

3. Isi ọrụ nke hydropyythyl methyl cellulose hpmc na mgbochi mmiri na-agụnye akụkụ kpamkpam, nke nke atọ bụ mmekọrịta mmiri na ciment. Ibelata mmiri nke ether na-adabere na mmiri mmiri nke isi, ihe mgbochi nke ngwa agha, ọkpụrụkpụ nke ngwa agha, na oge mwube ahụ. Onye kachasị elu nke hydropyylthylthyl methyl cellulose, mma njigide mmiri.

4.Factors na-emetụta njigide mmiri nke ngwa ikuku na-agụnye viocosis a, mgbakwunye ego, urughuru ogo na ọnọdụ okpomọkụ. Ọkachamara viscosity nke cellosuse eather, mmachi mmiri ka mma. Vissiosis bu oke ihe di nkpa nke oru HPMC. Maka otu ngwaahịa ahụ, nsonaazụ nke iji ụzọ dị iche iche iji tụọ vicessity dị iche iche, ụfọdụ nwekwara oghere ihu abụọ. Ya mere, ntụnyere viscosit ga-rụrụ n'ime otu ule ahụ, gụnyere okpomọkụ, spindle, wdg.

5.Gerilly na-ekwu okwu, viscosity dị elu, ka mma njigide mmiri ka mma. Agbanyeghị, viscosity dị elu, onye dị elu molecular arọ nke Hpmc na ala na-agbanwe agbanwe nke Hpmc, nke nwere mmetụta na-adịghị mma na ike na ịrụ ọrụ nke ngwa agha. The dị elu viscosity, ihe doro anya na-emetụta mmetụta nke ngwa agha, mana ọ naghị emetụta ya. The dị elu viscosity, ndị na-ahụ n'anya mmiri mmiri, arụmọrụ owuwu ahụ, arụmọrụ nke scros scraper na elu nke mkpụrụ. Ma, ike ịba ụba nke mmiri mmiri n'onwe ya anaghị enyere aka. Ihe owuwu abụọ ahụ enweghị arụmọrụ anti-SAG. N'ụzọ dị iche, ụfọdụ ndị na-ajụ oyi ma dị ala ma gbanwee hydropylthylthylthylthyl cellulose nwere arụmọrụ dị mma na imeziwanye ike nke ngwa agha mmiri.

6.Ele ka ukwuu ego nke cellulose ether na-agbakwunye na ngwa agha hpmc, ka mma mmiri dị elu, na mgbapụta viscosity, ka mma njigide mmiri. Finveness bụkwa ihe dị mkpa na ntanetị arụmọrụ nke hydroxyl methyl cellulose.

7.Ọ di na nha nke hydroxyppppppyl methyl cellulose nwekwara ụfọdụ mmetụta na njigide mmiri ya. Na mkpokọta, maka hydropyylthylthyl methyl cellulose nwere otu viscosite na ịdị mma dị iche iche, obere njigide ahụ na-emetụta otu mgbakwunye mmiri ahụ. Ọ ka mma.

8.ngbakwunye udu mmiri, mgbakwunye ego nke cellulose ether peret hpmc dị ala, mana ọ nwere ike ime ka arụmọrụ ihe owuwu nke mgbochi mmiri, ọ bụ isi ihe na-emetụta arụmọrụ nke ngwa agha. Ezi uche dị na ya hydropyythylthyl methyl cellulose, arụmọrụ nke ọgwụ mgbochi mmiri na-emetụta nke ukwuu.
