Hydroxypropyl methylcellulose nwere ike melite ihe mgbochi mgbasa nke ngwa ngwa ciment

Hydroxypropyl methylcellulose (HPMC)bụ ihe dị mkpa polymer compound nke a na-ejikarị eme ihe n'ubi ihe owuwu ụlọ, karịsịa na ciment mortar. Ọ na-akwalite ihe mgbochi mgbasa nke ngwa ngwa ciment na arụmọrụ ya dị mma, si otú ahụ na-eme ka arụmọrụ ihe owuwu na ịdịte aka nke ngwa agha dịkwuo elu.

1. Njirimara ndị bụ isi nke hydroxypropyl methylcellulose

HPMC bụ cellulose ether na-abụghị ionic enwetara site na-agbanwe cellulose eke ekemịkal. Ọ nwere ezigbo mmiri solubility, njigide mmiri na adhesion, ma gosipụta nkwụsi ike kemịkalụ dị elu na biocompatibility. N'ime ihe ndị sitere na ciment, AnxinCel®HPMC na-ebutekarị arụmọrụ nke ihe site na ịhazi mmeghachi omume hydration na omume viscosity.

2. Usoro nke melite mgbochi mgbasa ihe onwunwe nke ciment ngwa agha

Ngwongwo mgbochi mgbasa na-ezo aka n'ikike nke ngwa ngwa ciment iji nọgide na-eguzosi ike n'ezi ihe n'okpuru mmiri ịchafụ ma ọ bụ ọnọdụ ịma jijiji. Mgbe ịgbakwunye HPMC, usoro ya na-emeziwanye mgbochi mgbasa tumadi gụnyere akụkụ ndị a:

2.1. Ejikwa mmiri emelitere

Mkpụrụ ndụ HPMC nwere ike ịmepụta ihe nkiri hydration n'elu akụkụ ciment, nke na-ebelata oke ikuku nke mmiri ma na-eme ka ikike njigide mmiri dị mma. Njide mmiri dị mma ọ bụghị nanị na-ebelata ihe ize ndụ nke ịnwụ mmiri na mgbawa nke ngwa agha, kamakwa ọ na-ebelata mgbasa nke ihe ndị na-akpata mmiri na-efunahụ, si otú ahụ na-eme ka mgbochi mgbasa.

2.2. Mụbaa viscosity

Otu n'ime isi ọrụ nke HPMC bụ ịbawanye viscosity nke ngwa agha nke ukwuu. Nnukwu viscosity na-enye ohere ka a na-ejikọta ihe ndị siri ike na ngwa ngwa, na-eme ka o sie ike ịgbasa mgbe ejiri ike mpụga. Viscosity nke HPMC na-agbanwe na mgbanwe na ntinye uche na okpomọkụ, na nhọrọ ezi uche dị na ya nke mgbakwunye ego nwere ike nweta mmetụta kacha mma.

2.3. thixotropy emelitere

HPMC na-enye ngwa agha thixotropy dị mma, ya bụ, ọ nwere viscosity dị elu na steeti static, na viscosity na-ebelata mgbe ejiri ike shiee ya. Àgwà ndị dị otú ahụ na-eme ka ngwa agha dị mfe ịgbasa n'oge a na-ewu ụlọ, ma ọ nwere ike iweghachi viscosity ngwa ngwa na steeti static iji gbochie mgbasa na eruba.

2.4. Welie arụmọrụ interface

A na-ekesa HPMC n'otu n'otu na ngwa agha ahụ, nke nwere ike ịmepụta àkwà mmiri n'etiti ihe dị iche iche ma melite ike njikọ n'etiti ihe ndị ahụ. Ke adianade do, elu ọrụ nke HPMC nwekwara ike ibelata elu esemokwu n'etiti ciment ahụ, si otú n'ihu na-eme ka mgbochi mgbasa arụmọrụ.

3. Mmetụta ngwa na uru

N'ime oru ngo, ngwa ngwa ciment agwakọta ya na HPMC na-egosi mmụba dị ukwuu na arụmọrụ mgbochi mgbasa. Ndị a bụ ụfọdụ uru a na-ahụkarị:

Melite arụmọrụ ihe owuwu: Mortar nwere arụmọrụ mgbochi mgbasa siri ike dị mfe ịchịkwa n'oge a na-ewu ụlọ na ọ naghị adị mfe nkewa ma ọ bụ ọbara ọgbụgba.

Meziwanye ogo elu: A na-eme ka nrapanye nke ngwa agha dị n'elu ala, na elu mgbe plasta ma ọ bụ paving na-adị nro.

Mee ka ịdịte aka dịkwuo elu: Belata mmiri na-efunahụ n'ime ngwa agha ahụ, belata mmụba nke oghere nke mgbasasa na-akpata, wee si otú ahụ meziwanye njupụta na ịdịte aka nke ngwa agha ahụ.

4. Ihe na-emetụta ihe na njikarịcha atụmatụ

Mmetụta nke mgbakwunye HPMC nwere njikọ chiri anya na usoro ọgwụgwọ ya, ịdị arọ molecular na ọnọdụ gburugburu ebe obibi. Mgbakwunye nke kwesịrị ekwesị nke HPMC nwere ike imeziwanye arụmọrụ nke ngwa agha ahụ, mana oke mgbakwunye nwere ike iduga viscosity gabigara ókè ma na-emetụta ọrụ ụlọ. Atụmatụ kachasị mma gụnyere:

Ịhọrọ HPMC na ịdị arọ molekụla kwesịrị ekwesị na ogo nke nnọchi: HPMC nwere ịdị arọ molekụla dị elu na-enye viscosity dị elu, mana arụmọrụ na arụ ọrụ kwesịrị ịhazi ya dịka ngwa akọwapụtara.

Jikwaa nke ọma nke mgbakwunye: HPMC na-agbakwunyekarị na 0.1% -0.5% nke ịdị arọ nke ciment, nke kwesịrị ka edozi ya dịka mkpa dị n'ezie.

Lezienụ anya na ebe a na-ewu ihe: Okpomọkụ na iru mmiri nwere mmetụta dị ukwuu na arụmọrụ nkeHPMC, na a ga-edozi usoro ahụ n'okpuru ọnọdụ dị iche iche iji nweta nsonaazụ kacha mma.

Ngwa nke hydroxypropyl methylcellulose n'ime ụrọ ciment na-eme ka mgbochi mgbasa nke ihe ahụ dịkwuo mma, si otú a na-emeziwanye arụmọrụ ihe owuwu na ogologo oge nke ngwa agha ahụ. Site na nyocha miri emi na usoro nke AnxinCel®HPMC na imeziwanye usoro mgbakwunye ahụ, enwere ike itinyekwu uru arụmọrụ ya iji nye azịza dị elu maka ọrụ owuwu.
