Hydroxypppylthyl methyl cellulose nwere ike imeziwanye mgbakwunye nke ngwa agha ciment

Mgbasawanye mgbasa ozi bụ teknụzụ dị mkpa iji tụọ ogo nke mgbochi - chụpụ. Hydroxypylthylthyl methyl cellulose bụ mmiri na-agbanye mmiri, makwaara dị ka polymer-soluble. Ọ na-eme ka ngwakọta nke ngwakọta site na ịba ụba viscosity nke mmiri agwakọta. Ọ bụ ụdị polymeric osisi hydrophilic, nke enwere ike ịgbaji na mmiri ma na-etolite ihe ngwọta ma ọ bụ mmiri na-agbasasị. Nnwale na-egosi na mgbe ego nke usoro Nafhalene System na-abawanye, mgbakwunye nke ike nke ga-ebelata mgbakwunye nke ngwa agha ciment ọhụrụ. Nke a bụ n'ihi na Nafthtalene Sentiona Secorde dị elu nke dị mma na-ebelata na-ebelata bụ onye na-eme ka ihe owuwu ciment na-ebelata, na-eme ka ọ bụrụ nke mwepụta mmiri, ga-eme ka ọ bụrụ akụkụ nke akụkụ nke ciment. N'otu oge ahụ, achọpụtara ya na mmụba nke ọdịnaya HPMC, mgbasa nke osisi ciment dị mma karịa.

Isi ike nke ihe:

A na-etinye HPMC nke na-abụghị nke na-asọpụrụ na Witness Ntọala Ntanetị Ntanetị, yana ihe okike ga-aga C25. Mgbe ule dị mkpa, usoro ciment bụ 400KG, Consed Commed Agwakọta nke ọma, mmiri ciment na ikuku 28d, nkezi ike bụ 42.6MPA, nkezi Ike nke mmiri n'okpuru mmiri wụsara ihe dị elu nke 60mm na mmiri bụ 36.4MPA ruo ụbọchị 28, na ike ahụ guzobere na ikuku bụ 84.8%, na-egosi oke mmetụta.

1. Ihe mgbakwunye HPMC nwere mmetụta doro anya na ngwakọta ngwakọta. Site na mmụba nke usoro ọgwụgwọ HPMC, oge nrụpụta na-etolite nke ọma. N'okpuru otu ọnọdụ HPMC usoro, oge nrụpụta nke ngwa agha nke mmiri dị ogologo karịa nke ikuku. Njirimara a bara uru maka itinye mmiri n'okpuru.

2, gwakọtara ya na hydropyylthylthyl methyl cellulose nke ngwa agha ciment ọhụrụ nwere ezigbo cohesion, ọ fọrọ nke nta ọgbụgba ọbara ọgbụgba.

3, HPMC mosage na igba ogwu choro ibu uzo belatara ma megharia nke ukwuu.

4. Incorporation nke mmiri na-eme ka nsogbu na-abawanye nsogbu, mana ọ ga-achịkwa ya, ma ọ bụ na ọ ga-ebelata mkpọsa mmiri nke mmiri mmiri dị n'okpuru.

5. Ọ dị obere na usoro dị n'etiti HPMC agwakọta ciment ụgbụ, ma obere ọdịiche dị n'etiti mmiri awụsasịrị ciment ịwụsara ciment. Ihe dị ka afọ 28d n'okpuru mmiri na-atọgbọ. Isi ihe kpatara ya bụ na mgbakwunye nke HPMC nke ukwuu na-ebelata ọnwụ na mgbasa nke ciment n'oge mmiri na-awụpụ, kamakwa na-ebelata ogo ciment compaction. Na oru ngo a, n'okpuru onodu nke ihe ndi ozo di n'okpuru mmiri, a na - agwakọta ego HPMC dị ka o kwere mee.

6, tinye HPMC n'okpuru mmiri anaghị achụsasị ihe dị mma, na-achịkwa ego dị mma, na-ejikwa ike nke na-akpụzi ihe dị na mmiri bụ 84.8%, mmetụta ahụ dị mkpa.
