Hydroxypropyl Methyl Cellulose (HPMC) bụ ihe mgbakwunye kemịkalụ nke a na-ejikarị na ụlọ ọrụ ihe owuwu na ihe owuwu ma na-arụ ọrụ dị iche iche na kọmpụta.
1. Mmetụta njide mmiri
Hydroxypropyl methylcellulose nwere ezigbo njide mmiri. Nke a cellulose nwere ike ịmịkọrọ mmiri buru ibu ma jiri nwayọọ nwayọọ hapụ ya n'oge a na-ewu ya, si otú ahụ na-eme ka njide mmiri dị nke ọma dịkwuo mma. Ngwongwo njide mmiri na-enyere aka idowe mmiri zuru oke n'oge mmalite nke ike siri ike nke ihe ma gbochie mmiri ịpụpụ ngwa ngwa. Nke a dị mkpa maka nwayọọ nwayọọ mmepe nke ihe ike, mbenata omume nke cracks na ịgbatị anwụ ngwa ngwa nke ihe.
2. Melite arụmọrụ ihe owuwu
Ịgbakwunye hydroxypropyl methylcellulose na ihe nwere ike imeziwanye ọrụ ya. Ihe mgbakwunye a na-abawanye viscosity nke ihe, na-eme ka ọ dịkwuo mfe ịrụ ọrụ n'oge a na-ewu ma na-ebelata nkewa na ọbara ọgbụgba. Ọ na-eme ka kọnkịtị nwee mmetụta dị mma na nrapado nke ọma, si otú ahụ na-enyere aka melite arụmọrụ na ịdị mma nke ihe owuwu, karịsịa na ngwa ndị dị ka ngwa ngwa mix mmiri na ngwa ngwa na-edozi onwe ya.
3. welie mmanu mmanu
The colloid kpụrụ HPMC na aqueous ngwọta nwere ike inye mmanu mmanu. Mmanu mmanu a na-ebelata iyi na akụrụngwa na-akpụ akpụ n'oge njem na ntinye ihe. N'otu oge ahụ, ọ nwekwara ike na-ekesa ihe nke ọma karị, belata ibu na ngwá ọrụ igwe, ma melite arụmọrụ ụlọ na ndụ ọrụ nke ngwá ọrụ ihe owuwu.
4. Belata ọbara ọgbụgba na nkewa
HPMC na-arụ ọrụ nkwụsi ike na kọmpụta ma nwee ike ibelata ọbara ọgbụgba na nsogbu nkewa na kọmpụta. Nke a bụ n'ihi na HPMC nwere ike dịkwuo viscosity nke ihe slurry, si otú na-edebe siri ike irighiri evenly na-egbochi nkewa nke mmiri na ezi mkpokọta. Nke a dị mkpa iji meziwanye ịdị n'otu na ịdị mma zuru oke nke ihe ahụ.
5. Control shrinkage na cracking
Mmetụta na-ejigide mmiri nke hydroxypropyl methylcellulose na-enyere aka belata ọnụ ọgụgụ nke ihicha nke kọnkịrị, si otú ahụ na-ebelata ihe ize ndụ nke mgbawa. Concrete na-adịkarị mfe mgbawa n'ihi mmiri na-efu ngwa ngwa n'oge usoro ike na ihicha. HPMC nwere ike ibelata nsogbu a site n'ịkwado oke mmiri kwesịrị ekwesị ma melite nkwụsi ike nke kọmpụta.
6. gbuo oge ntọala
HPMC nwere mmetụta ụfọdụ nke igbu oge nhazi ma nwee ike ijikwa ọnụọgụ ntọala nke ihe. Nke a bara ezigbo uru na ụfọdụ ọnọdụ ihe owuwu pụrụ iche, ọkachasị n'oge ihu igwe na-ekpo ọkụ ma ọ bụ mgbe achọrọ njem ogologo oge. Ịkwụsị oge nhazi na-eme ka o doo anya na kọmpat ka na-asọba ma na-arụ ọrụ nke ọma mgbe ọ rutere ebe a na-ewu ihe.
7. Melite nguzogide friza-thaws
HPMC nwere ike melite ifriizi-thaws eguzogide nke ihe. Nke a bụ n'ihi na ya ọrụ nke idowe mmiri na melite pore Ọdịdị nwere ike ibelata ntu oyi heave mgbali nke ihe na ala okpomọkụ gburugburu, si otú mbenata mmebi nke ihe Ọdịdị mere ifriizi-thaws cycles.
8. Meziwanye nguzogide corrosion
Hydroxypropyl methylcellulose nwere ike ịbawanye njupụta nke kọnkịtị, belata porosity, ma gbochie ntinye mmiri na kemịkalụ na-emerụ ahụ. Ngwongwo a na-eme ka nguzogide corrosion nke kọnkịrị dịkwuo mma ma gbatịa ndụ ọrụ ya, ọkachasị na gburugburu ebe ekpughere ion chloride.
9. Kwalite arụmọrụ njikọ
HPMC na-enyere aka melite ike nkekọ dị n'etiti kọnti na ihe ndị ọzọ. Dịka ọmụmaatụ, mgbe ị na-agbanye ihe eji achọ mma dị ka taịlị na nkume seramiiki, HPMC nwere ike ịkwalite nrapanye nke ngwa agha ahụ, belata ịkwatu na oghere, ma hụ na ọ dị mma.
10. Green na gburugburu ebe obibi enyi
Dị ka ngwaahịa ether cellulose, hydroxypropyl methylcellulose nwere ezigbo biodegradability na enwechaghị mmetụta na gburugburu ebe obibi. N'otu oge ahụ, ọ nwekwara ike ibelata ọnụ ọgụgụ ciment a na-eji na kọmpụta, si otú ahụ na-ebelata ikuku carbon dioxide n'oge usoro mmepụta ma na-agbaso ihe nchebe gburugburu ebe obibi nke ụlọ akwụkwọ ndụ akwụkwọ ndụ.
Ọrụ nke hydroxypropyl methylcellulose na ihe dị iche iche na nke zuru oke, na-ekpuchi ọtụtụ akụkụ site na nkwalite arụmọrụ ụlọ ruo na nkwalite ịdịte aka. Site ezi uche ojiji nke HPMC, arụmọrụ na ewu àgwà nke ihe nwere ike budata mma izute chọrọ nke oge a na-ewu oru ngo maka elu-arụmọrụ ihe. Njide mmiri ya dị mma, mmanye na nkwụsi ike na-eme ka ọ bụrụ nke a na-apụghị dochie anya n'etiti ihe ụlọ.
