Enwere data nnwale ọ bụla nwere ike gosipụta mmetụta HPMC nwere na akụrụngwa ngwa agha?

Thermal na n'ibu Njirimara: ọmụmụ
Ọ na-egosi na HPMC nwere ike melite thermal na n'ibu Njirimara nke plasta ngwa agha. Site n'ịgbakwunye ọkwa dị iche iche nke HPMC (0.015%, 0.030%, 0.045%, na 0.060%), ndị nchọpụta ahụ chọpụtara na enwere ike ịmepụta ihe ndị dị nro na mbelata ịdị arọ nke 11.76% n'ihi nnukwu porosity nke HPMC kpatara. Nke a dị elu porosity na-enyere aka na mkpuchi ọkụ, na-ebelata conductivity eletrik nke ihe ahụ ruo 30% ka ị na-ejigide ọkụ ọkụ na-ekpo ọkụ nke ihe dịka 49 W mgbe a na-agbanye otu ọkụ ọkụ. Mgbochi na-ebufe ọkụ site na panel ahụ dịgasị iche na ọnụ ọgụgụ nke HPMC agbakwunyere, na ntinye kachasị elu nke ihe mgbakwunye na-eme ka 32.6% na-abawanye na nkwụsị okpomọkụ ma e jiri ya tụnyere ngwakọta ntụaka.

Njide mmiri, ịrụ ọrụ na ike: ọmụmụ ihe ọzọ
Achọpụtara na HPMC nwere ike ime ka njide mmiri dịkwuo mma, nchikota na nguzogide nke ngwa agha, ma mee ka ike tensile na ike njikọ nke ngwa agha dịkwuo mma. N'otu oge ahụ, HPMC nwere ike igbochi nhazi nke mgbawa rọba na ngwa agha ma belata ndetu mgbawa rọba. Njide mmiri nke ngwa agha na-abawanye ka viscosity nke HPMC na-abawanye. Mgbe viscosity nke HPMC karịrị 40000 mPa·s, njide mmiri anaghịzi abawanye nke ukwuu.

Usoro nnwale viscosity: Mgbe ị na-amụ usoro nnwale viscosity nke nnukwu viscosity hydroxypropyl methylcellulose
, chọpụtara na HPMC nwere ezigbo dispersion, emulsification, ndim, bonding, mmiri njigide na gluu njigide Njirimara. Ihe ndị a na-eme ka HPMC na-ejikarị eme ihe na ụlọ ọrụ ihe owuwu.

Nkwụsi ike olu: Ọmụmụ banyere mmetụta nke usoro onunu ogwu HPMC na nkwụsi ike mmalite nke Portland ciment-aluminate ciment-gypsum ternary composite onwe-leveling mortar
Ọ na-egosi na HPMC nwere mmetụta dị ukwuu na ịrụ ọrụ nke ngwa agha na-ebuli onwe ya. Mgbe etinyere HPMC, arụ ọrụ nke ngwa agha na-ebuli onwe ya dị ka ọbara ọgbụgba na nhazi nkewa na-abawanye nke ọma. Agbanyeghị, oke onunu ogwu anaghị akwado mmiri nke ngwa agha na-ebuli onwe ya. Usoro kachasị mma bụ 0.025% ~ 0.05%. N'otu oge ahụ, ka ọdịnaya HPMC na-abawanye, ike mkpakọ na ike mgbanwe nke ngwa agha na-ebuli onwe ya na-ebelata ruo ogo dị iche iche.

Mmetụta dị na ike nke ozu akwụkwọ ndụ akwụkwọ ndụ seramiiki kpụrụ plastik: nnwale
A mụrụ mmetụta nke ihe dị iche iche HPMC dị iche iche na ike mgbanwe nke seramiiki green ozu, wee chọpụta na ike na-agbanwe agbanwe na mbụ mụbara wee belata site na mmụba nke ọdịnaya HPMC. Mgbe ego mgbakwunye HPMC bụ 25%, ike ahụ ndụ ndụ bụ nke kachasị na 7.5 MPa.

Ịrụ ngwa ngwa ngwakọta akọrọ: ọmụmụ
Achọpụtara na ọnụọgụ dị iche iche na viscosities nke HPMC nwere mmetụta dị ịrịba ama na arụmọrụ arụ ọrụ na akụrụngwa nke ngwa agha agwakọta akọrọ. HPMC nwere ikike idowe mmiri na ito. Mgbe usoro onunu ogwu dị elu karịa 0.6%, mmiri mmiri nke ngwa agha na-ebelata; mgbe usoro onunu ogwu bụ 0.4%, njigide mmiri nke ngwa agha nwere ike iru 100%. Agbanyeghị, HPMC na-ebelata ike nke ukwuu, site na 75%.

Mmetụta na simenti-nkwado n'ụzọ zuru ezu oyi recycled mix: ọmụmụ
Achọpụtara na HPMC ga-ebelata ike mgbanwe na ike mkpakọ nke cement mortar specimens mgbe ciment hydration n'ihi ikuku-entraning mmetụta. Otú ọ dị, ciment na-hydrated na mgbasa nke HPMC etisasịwo na mmiri. E jiri ya tụnyere ciment nke a na-ebu ụzọ mee mmiri wee gwakọta ya na HPMC, a na-abawanye ike mgbanwe na mkpakọ nke ụdị simenti ngwa ngwa.

Ihe nyocha ndị a na nyocha nyocha na-egosi na HPMC nwere mmetụta dị mma n'ịkwalite njide mmiri nke ngwa agha, imeziwanye ọrụ ọrụ, na imeziwanye arụmọrụ okpomọkụ, mana ọ nwekwara ike inwe mmetụta na ike na nkwụsi ike nke ngwa agha. Ya mere, n'ime ngwa bara uru, ọ dị mkpa ka a họrọ usoro onunu na nkọwapụta nke HPMC n'ụzọ ezi uche dị na ya dabere na mkpa injinịa akọwapụtara na ọnọdụ gburugburu ebe obibi iji nweta arụmọrụ ngwa agha kacha mma.
