Hydroxypylthyl methyl cellulose na ciment

Gịnị bụ HPMC Hydropyylthyl methyl cellulose na ciment ruru?

Akwa mkpuchi mmiri nke injinia, ihe ya na-adabere na ụgbụ nke akụrụngwa mere: ihe eji eme ya, ihe eji eme ya eriri eji eme ihe 40-50, calcium kpụrụ 4-6,hydroxypylthyl methyl cellulose7-9, silicon carbide ntụ 40-4, coundy cydroxide ntụ ntụ 10-12, akọrọ, a mumixyyym Sound stachi 4-6, mmiri na-agbagharị carbon, mmiri 600-650; Mkpịsị mmiri nke injinia nke ngwaahịa a nwere mkpuchi siri ike, nguzosi ike na mgbidi, arụmọrụ siri ike gburugburu ebe obibi, na-egbochi ịda mba. Taa, anyị ga-ekwu maka viscosity nke hydroxyppyl methyl cellulose Aques? Ka anyị mụọ ya.

1. Onye na-ahụ maka molecular ibu, okpomọkụ nke osisi, ịkpụcha ọnụego na nnwale nke cellulose ether; 2 3. Nke kachasị elu nke cellulose ether, onye dị elu na viscosity nke ihe a anyị kwesịrị ị toa ntị na ntinye aka dị iche iche, ma metụta njirimara nke ciment na ciment. 4. Dị ka ọtụtụ n'ime ihe ngwọta, viscosity ahụ ga-agbadata na mmụba nke okpomọkụ, tinyere ihe dị elu na-enwe ihe dị elu nke cellose eth, ka njọ nke okpomọkụ; Na mgbakwunye, mmetụta dị iche iche na-adị iche iche dabere na ego mmiri ejiri maka Epoxy ciment.

Ngwọta osisi hydroxypyl methssisose A nwekwara ike ijikọ ihe na akụrụngwa nke mkpụrụ osisi, ma ọ bụrụ na virus na-enweghị oke, ga-emerụ ciment ciment ozugbo ọfụma. Banyere ụfọdụ ngwa agha nke onwe ya nwere mmiri dị elu, viscosity nke mkpụrụ osisi cellulose nke ikuku ga-akọwapụta.

Ihe other na-ahụ maka igwe na-eme bụ ahụ pseudoplastic, anyị na ọkwa nke nchọpụta nke a na-achọpụta na-egosi na ọnụego ya dị ukwuu, na viscosity dị obere.

Ya mere, iji kpokọta ya bụ: ike nke na-enweghị ike, nke na-aba uru nke mmiri injin na-abụghị, na-abawanye uru na-enweghị atụ, mmiri ga-abawanye na njirimara mmiri pseudoplastic.

Njikọ mmiri site na hydroxylthylthylthyl methyl cellulose bụ otu n'ime ihe ndị dị mkpa nke hydropyythlthyl methyl cellulose. A na-eme ka okpomọkụ kpuchie ọdịnaya mmiri na-emetụta ya na ngwa agha, okpomoku na nrụgide na ọnụego ya. Ya mere, na oge dị iche iche, gbakwunye hydropyylthylthylthyl methyl cellulose otu ego nke arụmọrụ mmiri nwere ụfọdụ ọdịiche.

Na mkpokọta, viscosity nke hydroxyl methyl cellulose bụ, ma ihe ọjọọ nke njigide mmiri ga-adị, ma a ga-ebelata ihe vinent na njigide mmiri mgbe viscosit karịrị 100,000. s. Mgbe viscosity nke hydroxypyl methyl cellulose gafere 100,000, ọnụego mgbochi mmiri nwere ike ịbawanye mma site na ịbawanye ego nke hydropyythylthylthyl methyl cellulose.

Na usoro ihe owuwu zuru ezu, enwere ike idozigharị mmiri nke slurry nwere ike idozi site na idozi ego nke hydropyyl methyl cellulose. Ngwa ngwa ngwa usoro usoro ngwaahịa cellulose nwere ike idozi nsogbu nke njigide mmiri n'okpuru okpomọkụ na-aga n'ihu. Na oge okpomọkụ dị elu, karịsịa na ebe na-ekpo ọkụ na na-agwụ ike na nke na-arụ ọrụ na anwụ na-acha, a na-achọ ka ọ dị elu iji zụlite mmiri nke slurry.

Okedị dị elu nke hydropyyl methyl cellulose, ọ nwere ike ịzụlite agbụ na oxyges, wee nwee ike ịmalite ihu igwe dị iche iche na-akpata ya site na eriri okpomọkụ nke ukwuu site na mmiri mmiri.

Ogo dị elu nke hydropyyl methyl cellulose nwere ike ịtọpụ ala na ngwa ahịa a na-eji nwayọọ nwayọọ na-agbapụta, na-eme ka ọ dị ogologo oge mmeghachi omume, ma na-eme ka njigide nke akụrụngwa na-eme ka ike na ike tensile. Na kwadebe usoro owuwe ihe owuwu dị elu dị elu, kwesịrị iru mmiri nke ngwaahịa hydroxyl, gbapụta ya na njikọta ọnụ na obi abụọ, tinyere ya na onye ọrụ na-arụ ọrụ ike. Ka ọnọdụ okpomọkụ na-ada, ego nke hydropyl methyl cellulose nwere ike belata ma enwere ike iru otu njide mmiri.

Ọ bụrụ na agbakwunyeghị ewer, chromatography nke ngwa ngwa ciment ga-eme ngwa ngwa, enweghị ike ịmịpụta ciment n'ụzọ nkịtị, na-ebute ngwa agha cent enweghị ike isi ma na-enweta nraranye ka mma. N'otu oge ahụ, mgbakwunye nke celhulose eate na-eme ka cent cent cent nwere ezigbo nsogbu na mgbanwe mgbanwe, ma na-eme ka njikọ njikọ ciment siri ike.
