Hydroxypropyl methylcellulose (HPMC)bụ ether cellulose na-abụghị ionic nke a na-ejikarị eme ihe na ụlọ ọrụ ihe owuwu ụlọ. Isi ọrụ ya n'ime ihe owuwu ụlọ bụ ịkwalite ịrụ ọrụ ihe owuwu, melite njide mmiri na ntinye nke ihe, ma melite arụmọrụ nhazi nke ihe. HPMC abụrụla ihe mgbakwunye dị mkpa maka ọtụtụ ngwaahịa ihe owuwu n'ihi njirimara kemịkalụ ya na nke anụ ahụ. A na-eji ya eme ihe n'ọtụtụ ebe na ihe owuwu ụlọ dị ka ngwa ngwa ciment, nrapado tile, ntụ ntụ, mkpuchi, na ngwaahịa gypsum. Ndị a bụ njirimara na uru nke HPMC n'ihe eji arụ ụlọ:
1. Njirimara nke HPMC na ihe owuwu ụlọ
Ezigbo njide mmiri
Otu n'ime ihe ndị a ma ama nke HPMC bụ njide mmiri ya dị mma. N'ihe ndị sitere na ciment na gypsum, HPMC nwere ike belata nhụsianya mmiri nke ọma, gbochie ihicha ciment na gypsum n'oge, ma melite iguzosi ike n'ezi ihe nke mmeghachi omume hydration, si otú ahụ na-eme ka ike na nrapanye nke ihe dị elu.
Melite arụmọrụ ihe owuwu
N'oge usoro ihe owuwu, HPMC nwere ike ime ka ngwa ngwa rụọ ọrụ ma mee ka ihe owuwu dị nro. Ọ nwere ike melite mmanu ihe nke ọma, belata esemokwu n'oge a na-ewu ihe, na-eme ka nchacha bụrụ otu na nke dị ire, ma melite arụmọrụ ụlọ.
Adhesion emelitere
HPMC nwere ike ime ka adhesion nke ihe ndị dị ka ciment na gypsum dịkwuo mma, nke mere na ngwaahịa ndị dị ka ngwa agha, ntụ ntụ, na nrapado taịl nwere ike ịkwado ya na ala ala, belata nsogbu ndị dị ka oghere na ịdaba, ma melite ndụ ọrụ nke ihe ụlọ.
Gbanwee ndakọrịta ihe
HPMC nwere ike gbanwee viscosity nke ihe ụlọ iji gbochie ngwa agha site na stratifying, ọbara ọgbụgba ma ọ bụ sagging n'oge agwakọta na ewu, nke mere na ọ nwere mma nkwusioru na edo edo, na mma ewu mmetụta.
Ogologo oge ọrụ
HPMC nwere ike ịgbatị oge oghere nke ihe dị ka ngwa agha na putty, ka ndị ọrụ na-ewu ụlọ nwee oge iji dozie na mezie, melite ogo ihe owuwu, na ibelata ihe mkpofu.
Melite mgbochi sagging
Na tile nrapado na putty ntụ ntụ, HPMC nwere ike melite mgbochi-sagging ikike nke ihe, nke mere na ọ na-anọgide na-akwụsi ike mgbe e wuchara na ọ dịghị mfe slide, na melite ziri ezi na aesthetics nke pasting.
Iguzogide ihu igwe na nkwụsi ike
HPMC ka nwere ike ịnọgide na-arụ ọrụ ya na oke okpomọkụ, iru mmiri ma ọ bụ gburugburu ebe obibi siri ike, na-ahụ na nkwụsi ike nke ihe ụlọ na-adịte aka, ọ gaghị emetụta àgwà ụlọ n'ihi mgbanwe gburugburu ebe obibi.
Nchekwa gburugburu ebe obibi na adịghị egbu egbu
Dị ka ihe sitere na cellulose sitere n'okike, HPMC adịghị egbu egbu na enweghị mmerụ ahụ, na-emezu ihe nchebe gburugburu ebe obibi chọrọ, enwere ike iji ya mee ihe na ụlọ akwụkwọ ndụ akwụkwọ ndụ.
2. Ngwa kpọmkwem na uru nke HPMC na ihe owuwu ụlọ
Ngwa ngwa ciment
HPMC nwere ike ime ka mmiri simenti na-ejigide mmiri, gbochie ngwa ngwa ka ọ ghara ịsa ngwa ngwa, belata ihe ize ndụ nke ịgbawa, meziwanye adhesion, mee ka ihe owuwu dị nro, na imeziwanye ihe mgbochi, nke mere na ngwa agha ahụ adịghị mfe ịkwanye mgbe a na-arụ mgbidi kwụ ọtọ.
Tile nrapado
Na nrapado taịlị, HPMC na-eme ka ike nkekọ na ihe ndị na-egbochi mwepu, na-ahụ na enwere ike itinye taịlị, ebe ọ na-eme ka arụ ọrụ nke ihe owuwu na-arụ ọrụ, na-ebelata ịrụ ọrụ, yana imeziwanye arụmọrụ ihe owuwu.
Putty ntụ ntụ
N'ime ntụ ntụ ntụ, HPMC nwere ike imeziwanye arụmọrụ ihe owuwu nke putty, mee ka nchacha dị nro, belata ntụ ntụ, meziwanye adhesion nke putty, ma gbochie putty oyi akwa ka ọ ghara ịgbawa ma daa.
Ngwaahịa gypsum
N'ime ihe eji ewu ụlọ (dị ka gypsum putty, gypsum adhesive, gypsum board, wdg), HPMC nwere ike ime ka njide mmiri nke gypsum dịkwuo mma, mee ka ike njikọ ya dịkwuo elu, ma mee ka ngwaahịa gypsum dịkwuo mfe ma dịgidere.
Agba na agba latex
Na agba mmiri na agba latex, HPMC nwere ike iji mee ihe dị ka ihe na-ekpo ọkụ na nkesa na-eme ka mmiri dịkwuo mma, gbochie mmiri ozuzo pigmenti, meziwanye mmetụta brushing nke agba ahụ, na-eme ka adhesion na nkwụsị mmiri nke ihe nkiri agba.
Ngwa agha na-ebuli onwe ya
N'ime ngwa agha na-ebuli onwe ya, HPMC nwere ike imeziwanye mmiri ya, mee ka ngwa agha ahụ kesaa nke ọma n'oge a na-ewu ụlọ, kwalite mmetụta ọkwa, ma welie nkwụsị mgbawa.
Ngwa mkpuchi mkpuchi
N'elu mgbidi mkpuchi mgbidi dị n'èzí, HPMC nwere ike imeziwanye ike njikọ nke ngwa agha ahụ, mee ka ọ dịkwuo mma na mgbidi ahụ, ma n'otu oge ahụ na-emeziwanye ihe owuwu ahụ ma hụ na nkwụsi ike nke mkpuchi mkpuchi.
Dị ka ihe mgbakwunye ụlọ na-arụ ọrụ nke ọma,HPMCa na-ejikarị ciment dị iche iche na ihe ndị dabeere na gypsum. Njide mmiri ya magburu onwe ya, ihe na-eme ka ọ dịkwuo mma, nkwụsi ike na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe dị mkpa na ụlọ ọrụ mmepụta ihe. Mgbe ị na-ahụ na arụmọrụ nke ihe owuwu ụlọ, HPMC nwekwara ike imeziwanye arụmọrụ ihe owuwu, belata ihe onwunwe, ma melite ogo ụlọ, na-enye ihe ngwọta dị mma maka ihe owuwu nke oge a. Site na mmepe nke teknụzụ ihe owuwu, ngwa ngwa nke HPMC ga-aga n'ihu na-agbasa ma na-arụ ọrụ dị mkpa na ihe ụlọ akwụkwọ ndụ akwụkwọ ndụ na gburugburu ebe obibi.
