HPMC (Hydroxypropyl Methylcellulose) bụ ihe eji eme ihe n'ọtụtụ ebe na-ewu ụlọ ma nwee ihe anụ ahụ na kemịkal pụrụ iche. A na-ejikarị HPMC eme ihe dị ka ihe mgbakwunye na ụlọ ọrụ ihe owuwu iji melite njirimara nke ihe owuwu ụlọ, karịsịa na ngwa agha, ntụ ntụ, mkpuchi na ngwaahịa ciment.
1. Ngwa na ngwa agha
N'ime ngwa agha ihe owuwu, a na-eji HPMC eme ihe n'ọtụtụ ebe iji melite arụmọrụ ihe owuwu. Njide mmiri ya, njupụta na mgbochi sag na-eme ka HPMC na-arụ ọrụ dị mkpa na ngwa ngwa agwakọta agwakọta, akwa tile seramiiki, ngwa agha masonry na ubi ndị ọzọ.
Njide mmiri: HPMC nwere ike imeziwanye ikike njide mmiri nke ngwa agha ma gbochie mmiri ịpụ ngwa ngwa, si otú ahụ hụ na hydration zuru oke nke ciment na melite ike njikọ na mgbape mgbochi nke ngwa agha. Njirimara a dị mkpa karịsịa na gburugburu ebe okpomọkụ dị elu ka ịzenarị mgbawa na ike na-efu site na ihicha ngwa ngwa buru ibu.
Ọkpụkpụ: HPMC nwere ike ịhazigharị mmiri na viscosity nke ngwa agha, na-eme ka ngwa agha ahụ dị nro n'oge ngwa yana mfe ịrụ ya. N'otu oge ahụ, ọ nwekwara ike imeziwanye wettability na adhesion nke ngwa agha na ihe ndị dị n'okpuru, na-eme ka ọkpụkpụ ahụ sie ike na mgbidi ma ọ bụ ihe ndị ọzọ dị n'okpuru.
Anti-sag: HPMC nwere ike igbochi ngwa agha ahụ ka ọ ghara ịsagharị ma ọ bụ na-akụda mgbe a na-arụ ọrụ n'elu elu, karịsịa mgbe a na-arụ nnukwu akwa. Ọrụ ngbanwe viscosity ya nwere ike idobe ngwa agha ahụ n'ụdị dị mma n'oge a na-ewu facade na ọ naghị adị mfe ịdapụ.
2. Ngwa na seramiiki tile adhesives
N'etiti ceramic tile adhesives, HPMC na-ejikarị eme ihe iji kwalite arụmọrụ njikọ yana ịrụ ọrụ nke taịlị seramiiki. N'ime ihe owuwu nke oge a, a na-eji taịlị seramiiki eme ihe n'ọtụtụ ebe maka mgbidi na ihe ịchọ mma nke ala, ya mere àgwà nke nrapado dị oké mkpa.
Ike njikọ dị mma: HPMC na-eme ka mmeghachi omume hydration zuru oke nke ciment site na njigide mmiri ya na mmetụta na-eme ka ọ dịkwuo mma, si otú a na-eme ka ike njikọ dị n'etiti nrapado na taịlị seramiiki na mkpụrụ. Nke a ọ bụghị nanị na-agbatị ndụ ọrụ nke taịl nile, ma na-egbochikwa ha ịdaba n'ihi ezughị ezu adhesion.
Oge mmeghe agbatịkwuru: N'oge usoro ịtọgbọ tile seramiiki, ndị na-arụ ụlọ na-achọkarị oge zuru oke iji dozie ọnọdụ taịlị seramiiki. Mgbakwunye nke HPMC nwere ike ịgbatị oge mmeghe nke nrapado, na-enye ndị na-arụ ọrụ ihe owuwu oge iji rụọ ọrụ na ịhazigharị, si otú ahụ na-emeziwanye arụmọrụ ụlọ.
Gbochie slimi: Mgbe ị na-edobe taịlị seramiiki na facade, HPMC nwere ike igbochi taịlị seramiiki nke ọma ka ọ ghara ịfe ma jikwaa kwụsie ike n'oge a na-ewu ụlọ. Nke a ọ bụghị nanị na-ebelata ihe isi ike nke ihe owuwu, kamakwa ọ na-eme ka ọ dịkwuo mma.
3. Ngwa na putty ntụ ntụ
Ọrụ nke HPMC na putty ntụ ntụ dịkwa oke mkpa, tumadi n'ịkwalite ọrụ ọrụ, njigide mmiri na nkwụsị mgbape nke putty.
Ọrụ dị mma: Ịtinye HPMC na ntụ ntụ ntụ ntụ nwere ike ime ka ntinye nke putty dị nro ma zere ncha, nkụ na ihe ndị ọzọ n'oge usoro ihe owuwu. N'otu oge ahụ, a pụkwara imeziwanye mmiri na ductility nke putty, na-eme ka owuwu dị mfe.
Ejikwa mmiri emeziwanye: Ọrụ njide mmiri nke HPMC nwere ike hụ na etinyere putty n'ụzọ zuru ezu na mgbidi ahụ, na-ezere mgbawa ma ọ bụ wepụ ntụ ntụ n'ihi nkwụsị mmiri ngwa ngwa. Karịsịa na mpaghara akọrọ ma ọ bụ nke dị elu, HPMC nwere ike igbu oge na mmiri evaporation nke ọma, na-eme ka njikọ dị mma nke putty na mkpụrụ.
Melite nguzogide mgbawa: N'oge usoro ihicha, putty nwere ike ịgbawa n'ihi mfu mmiri na-enweghị isi. HPMC, site na ikike njigide mmiri ya, na-enye ohere ka putty kpochaa nke ọma, si otú a na-ebelata ihe ize ndụ nke mgbawa.
4. Ngwa na mkpuchi
HPMC na-ekerekwa òkè n'ịdị arọ, njide mmiri na nkwụsi ike na mkpuchi mmiri.
Mmetụta siri ike: Na mkpuchi, HPMC na-ejikarị emezigharị viscosity nke mkpuchi ahụ, na-eme ka mkpuchi ahụ dịkwuo n'otu n'oge a na-ehichapụ ma ọ bụ ịgbasa, ma nwee ọkwa dị mma na ịrụ ọrụ. N'otu oge ahụ, ọ nwere ike igbochi agba ka ọ ghara ịdaba ma hụ na eserese eserese.
Njide mmiri: HPMC nwere ike igbochi mkpuchi ịpụ ngwa ngwa n'oge a na-ewu ụlọ, nke na-emetụta àgwà ụlọ. Karịsịa na gburugburu ebe okpomọkụ dị elu ma ọ bụ ọnọdụ ikuku na-adịghị mma, njigide mmiri nke HPMC nwere ike ime ka mmetụta nrụpụta nke mkpuchi dịkwuo mma.
Mmetụta nkwụsi ike: HPMC nwekwara ike ịkwalite nkwụsi ike nchekwa nke mkpuchi, gbochie delamination na mmiri ozuzo nke mkpuchi n'oge nchekwa ogologo oge, ma nọgide na-enwe otu na nkwụsi ike nke mkpuchi.
5. Ngwa na ngwaahịa ciment
A na-ejikwa HPMC n'ọtụtụ ebe na ngwaahịa ciment precast na ihe n'ala na-eme ka onwe ya. Ọ nwere ike melite nguzogide mgbape, ike mkpakọ na ire ụtọ nke ngwaahịa ciment.
Mmezi mgbape mgbape: Mmetụta njide mmiri nke HPMC na-eme ka a hụ na ciment agaghị agbawa n'ihi ngwa ngwa evaporation nke mmiri n'oge usoro siri ike, si otú a na-emeziwanye ogo na ịdịte aka nke ngwaahịa ahụ.
Meziwanye ogo elu: HPMC na-eme ka elu nke ngwaahịa ciment dị nro ma dị nro, na-ebelata ọgbọ nke egosipụta na mgbawa, ma na-eme ka ọdịdị dị mma nke ngwaahịa emechara.
Meziwanye arụmọrụ ihe owuwu: N'ime ihe n'ala nke na-ebuli onwe ya, mmetụta na-abawanye ụba nke HPMC nwere ike imeziwanye mmiri nke ihe ahụ, na-eme ka owuwu ala ahụ dịkwuo n'otu na nke dị larịị, na-ezere mmezi na-enweghị isi na mgbawa.
6. Ngwa ndị ọzọ
Na mgbakwunye na ngwa ndị a dị n'elu, HPMC na-arụkwa ọrụ dị mkpa na ihe mkpuchi mmiri, ihe mkpuchi, ihe mkpuchi na mpaghara ndị ọzọ. N'ime ihe ndị na-egbochi mmiri, njigide mmiri ya na ihe ndị na-eme ka ọ dịkwuo mma nwere ike imeziwanye arụmọrụ ihe owuwu na mmetụta mgbochi mmiri nke ihe ahụ; n'etiti ihe mkpuchi ọkụ, HPMC na-enyere aka melite ike njikọ na nkwụsi ike nke ihe.
Ngwa obosara nke HPMC n'ọhịa ihe owuwu bụ n'ihi njirimara anụ ahụ na kemịkal ya dị mma. Dị ka ihe dị mkpa na-ewu ihe mgbakwunye, HPMC nwere ike ọ bụghị nanị melite mmiri njigide, ndim na mgbape eguzogide nke ihe, ma budata mma ewu arụmọrụ na okokụre ngwaahịa àgwà. N'ime ihe owuwu nke oge a, ma ọ bụ ngwa agha, ihe ntanye tile, ntụ ntụ ntụ, mkpuchi na ngwaahịa ciment, HPMC na-arụ ọrụ na-enweghị atụ, na-akwalite ọganihu nkà na ụzụ nke ihe owuwu ụlọ na imeziwanye arụmọrụ ụlọ.
