Mmetụta HPMC na ụdị ciment dị iche iche

Hydroxypyl Methylcellose (hpmc) bụ mmiri polymer na-enweghị mmiri, nke a na-ejikarị ya rụọ ọrụ, karịsịa na ụdị ihe ndị mejupụtara ciment. HPMC nwere ezigbo adhesion, na-etolite mmiri, na-akpụ akpụ ihe nkiri na ngbanwe, nke ngwa agha, ego nke mgbakwunye na ọnọdụ iji.

1. Ihe njirimara na ọrụ nke HPMC
Dị ka ihe mgbakwunye na ciment, HPMC tumadi na-emetụta arụmọrụ nke ciment site na usoro ndị a:

Ndobe mmiri: HPMC nwere ike igbu oge na-egbu oge mmiri na ciment mado na ciment ma zere ịgbagọ agbagọ site na oke mmiri na-akpata oke mmiri.
Mmetụta dị iche iche: HPMC nwere mmetụta na-arụsi ike, nke nwere ike ime ka cimekwuota ebe a na-edo edo ma kwalite ụlọ mkpuchi ahụ.
Mmeziwanye RENEOology: HPMC nwere ike ịgbanwe ihe ndị na-egbu egbu nke ciment, na-eme ka ọ nwee mmiri dị mma ma na-egbochi mkpuchi na-eme n'oge owuwu.
Ihe onwunwe na-egbochi:

2. Mmetụta HPMC na ụdị ciment dị iche iche
(1) nkịtị Portland ciment (OPC)
A na-eji ciment nkịtị. Ọrụ HPMC n'ime ya bụ gosipụtara gosipụtara akụkụ ndị a:

Mmeziwanye ọrụ: Mgbe ị na-eji OPC, a na-agbakwunyekwa ụfọdụ mmiri. HPMC nwere ike melite akụrụngwa ya na nkwụsi ike nke slurry site na ndị na-egbochi ciment na-agafe ngwa ngwa ma ọ bụ ihicha ngwa ngwa.
Oge na-egbu oge Ọnọdụ: HPMC nwere ike igbu oge ntọhapụ nke ciment ma gbochie ciment site na mbido. Ọ dị mma nke ọma maka nnukwu ihe owuwu ma ọ bụ gburugburu ebe obibi dị elu.
Na-eme ka njigide mmiri na-eme ka njigide mmiri na-eme ka mmiri sie ike mmiri, na-egbochi mmiri ịmịcha ngwa ngwa n'oge usoro ịgwọ ọrịa, si otú a na-eme ka ike mmepe ciment.

(2) cimemina cimemina dị elu
N'ihi oke nke ala allumerition na kemịkalụ kemịkal ya, ciment-alumina nwere oke ike ngwa ngwa. Agbanyeghị, n'ihi nnukwu hydration kpo oku nke cimem cimem dị elu, cracks na nsogbu ndị ọzọ na-eme n'oge a na-ewu. Ihe mgbakwunye HPMC nwere ike ime ka ihe ndị a na-eso) mee ka ihe ndị a:

Oge mmeghachi omume hydration na-egbu oge: HPMC nwere ike igbu oge mmeghachi omume hydration nke ciment, karịsịa na mmalite nke ciment na-enweghị ike, belata hydration na-egbochi cracks.

Mmeziwanye udu mmiri: cime pace nke ciment alumina enweghị ezigbo mmiri. HPMC na - enyere aka ime ka ahụ dịkwuo mma na ụlọ ọrụ na - arụ ọrụ site na ịba ụba viscosict ma na - eme ka nkwụsi ike nke mado.

Na-eme ka njigide na-egbochi: Njikọ mmiri nke Hpmc na-eme ka ọnọdụ ịgwọ ọrịa na-eme ka ọ ghara ịgwọ ọrịa dị elu ma zere ịgba mmiri site na mmiri na-akpata oke mmiri.

(3) ciment ọcha
A na-ejikarị ciment na ụlọ ịchọ mma na ụlọ ọrụ pụrụ iche. Ihe mmetụta nke HPMC na Cents Ciment bụ:

Mee ka ndọnye aka na-agbanwe agbanwe na mmiri na-eguzosi ike: HPMC nwere ike iwelie ike nke ciment, karịsịa na gburugburu iru mmiri. A na-ejikarị ciment ọcha na mkpuchi mgbidi dị na ya. Ihe mgbakwunye HPMC nwere ike ịkwalite nguzogide mmiri na nguzosi iche iche.
Meziwanye mmiri na arụmọrụ owuwu: ciment ciment chọrọ mmiri dị oke na otu owuwu. HPMC nwere ike imeziwanye ịdị n'otu nke slurry, zere igbochi ciment na-ewu ewu n'oge owuwu, ma hụ na ewepụghị ụdị mkpuchi.

(4) Cimening cimening
Cimen siri ike na-eme ngwa ngwa nwere ngwa ngwa hydration ma dịkwa mma maka ọrụ chọrọ owuwu ngwa ngwa. Ngwa nke HPMC na cimening ciment na-egosi na:

Oge oge ntọala:
Na-agbanwe ọnụego hydration: hpmc nwere ike ịgbanwe ọnụego ciment site na imeziwanye viscosit na rheuloulouloulouch Njirimara nke ciment, na-eme ka ọ na-eme ka ọ na-emegharị ihe dị iche iche.
Kwalite ikike nke oge owuwu: ojiji nke HPMC nwere ike ịgbatị oge ndị mmadụ na-emeghe, na-enye ndị ọrụ ihe owuwu ọzọ iji mee mgbanwe na owuwu.

(5) obere ciment
A na-ejikarị ciment okpomoku dị obere na nnukwu ihe ọrụ dị ukwuu iji belata ọkụ wepụtara n'oge ciment hydration. Ọrụ HPMC na obere ciment na-agụnye:
A na-ejikarị hydration kpo oku: A na-ejikarị ciment dị obere na ọnọdụ ebe ekwesịrị ịchịkwa. HPMC nwere ike ịchịkwa mmiri ciment nke ọma ma belata mkpokọta nke oge hydration ọkụ, si otú ahụ na-ezere ọgbọ nke ụdị ọdịiche dị iche iche.
Idozi ụdị mmiri nke ciment: Ebe ọ bụ na a na-ejikarị ciment obere olu na-awụkwasị nnukwu olu, mmiri na-ejide mmiri nwere ike idobe ooh ma na-akwalite etolite ike.

3. Na-akpachapụ anya na HPMC
Ọ bụ ezie na Hpmc na-arụ ọrụ nke ọma na ciment, ojiji na-agakarị ịtụle ihe ndị a:

Njikwa usoro: ego nke HPMC gbakwunyere na ọ dị ka ụdị ciment na mkpa dị n'ezie. Ọ bụrụ na agbakwunye nke ukwuu, ọ nwere ike imetụta ike na ike nke ciment; Ọ bụrụ na agbakwunye obere, apụrụghị ịrụ ọrụ ya n'ụzọ zuru ezu.
Ngụkọta na nti ihe ndị ọzọ: HPMC nwere ike isonye ụfọdụ na-etinye obi ụtọ (dịka ndị na-emebi mmiri, ndị ọrụ ike mbụ, wdg), yabụ achọrọ ka achọrọ.
Nchekwa nchekwa nke ciment: arụmọrụ nke HPMC na ciment na ebe nchekwa na-emetụta ciment. Ya mere, na arụ ọrụ n'ezie, a ga-akwụrịrị nlebara anya na nchekwa ọnọdụ ciment iji zere ọdịda nke ciment.

Dịka ihe simenti ciment, Hpmc na-arụ ọrụ dị mkpa na ụdị ciment dị iche iche. Ọ nwere ike bulite arụmọrụ arụmọrụ na ogo ikpeazụ nke ciment site na imeziwanye ihe mgbochi ciment, na-egbu oge ọnọdụ ntọala, ma na-eme ka njigide mmiri na-eme ka mmiri sie ike. Dabere na njirimara nke ụdị ciment dị iche iche, nke ezi uche dị na ya nke mgbakwunye ego ma jiri usoro HPMC nwee ike iji mmepe arụmọrụ ciment ma zute mkpa owuwu dị iche iche.
