HPMC (hydroxypropyl methylcellulose) bụ ihe eji arụ ụlọ dị mkpa, ọkachasị n'ọtụtụ ebe na usoro owuwu dịka ịtọgbọ tile. Ọ bụ ether cellulose na-abụghị ionic enwetara site na mgbanwe kemịkalụ nke eriri owu eke eke. HPMC na-arụ ọrụ dị mkpa na adhesives tile n'ihi ọmarịcha arụmọrụ ya.
1. Mmetụta dị arọ
HPMC nwere ezigbo ihe na-eme ka ọkpụkpụ, nke nwere ike ịbawanye viscosity nke adhesives tile, na-eme ka ọ dị mfe ịgbasa n'elu ihe owuwu ma nọgide na-eji ngwa ngwa. Ngwongwo na-eme ka ọ dịkwuo mma ọ bụghị nanị na-eme ka arụ ọrụ nke ịrụ ọrụ dịkwuo mma, ma na-enyere aka ịnọgide na-enwe ogologo oge na-emeghe n'oge a na-ewu ụlọ, ya bụ, a pụrụ imezi taịl nile n'ọnọdụ maka oge mgbe ngwa.
2. Njide mmiri
Ọrụ ọzọ dị mkpa nke HPMC bụ njide mmiri. N'oge a na-eji nrapado tile eme ihe, a na-achọ ntakịrị mmiri iji hụ na simenti ma ọ bụ ihe ndị ọzọ simenti nwere ike ịgbakọta ma sie ike. Ọ bụrụ na mmiri na-efunahụ ngwa ngwa, ihe simenti na-enweghị ike imeghachi omume n'ụzọ zuru ezu, na-ebute mbelata ike njikọ. HPMC nwere ike igbochi mmiri n'ụzọ dị irè, na-edobe mmiri dị na nrapado, ma nye nrapado oge zuru ezu iji sie ike na ịmepụta akwa njikọ siri ike.
3. Anti-slip onwunwe
N'ebe a na-edobe tile, ihe mgbochi mgbochi dị ezigbo mkpa n'ihi na taịl nile dị mfe ịkwanye mgbe etinyere ya na mgbidi ma ọ bụ n'elu kwụ ọtọ. HPMC na-abawanye thixotropy nke nrapado, n'ịhụ na taịl nile nwere ike guzosie ike na vetikal na-ebupụta na-enweghị slide, si otú na-emeziwanye izi ezi nke ewu.
4. Na-agbatị oge oghe
N'oge usoro ihe owuwu ahụ, oge a na-emeghe na-ezo aka na windo oge nke nrapado tile na-anọgide na-adịgide adịgide nke ọma mgbe etinyere ya. HPMC nwere ike ịgbatị oge mepere emepe nke ọma, na-enye ndị ọrụ ohere ịhazigharị na idobe taịlị ruo ogologo oge, na-emezi mgbanwe nke ihe owuwu, ọkachasị dabara adaba maka nhazi nnukwu ma ọ bụ ọnọdụ ihe owuwu dị mgbagwoju anya.
5. Ịkwalite ike njikọ
HPMC nwekwara ike imeziwanye ike njikọta nke nrapado tile. Mgbe eji ya na inorganic ihe dị ka ciment, ọnụnọ nke HPMC nwere ike budata welie bonding Njirimara nke nrapado, n'ịhụ na tọrọ tile na-eguzosi ike na-adịghị ada apụ mgbe agwọ ọrịa, na-na-na-na ha kwụsie ike ruo ogologo oge.
6. Ịkwalite ịrụ ọrụ ihe owuwu
Mmanya nke HPMC na-eme ka nrapado dị mfe itinye, karịsịa n'oge ntinye buru ibu, ọ nwere ike ime ka ngwa ahụ dịkwuo nro ma belata mgbatị anụ ahụ nke ndị ọrụ ụlọ. N'otu oge ahụ, ndị magburu onwe dispersibility nke HPMC nwere ike ime ka dị iche iche components evenly kesaa n'oge edemede, si otú melite uniformity nke ngwakọta.
7. Mgbochi ihu igwe na nguzogide friza-thaw
N'ihi nguzogide ihu igwe ya dị mma yana nguzogide ifriizi, HPMC nwere ike igosi arụmọrụ kwụsiri ike n'okpuru ọnọdụ ihu igwe dị iche iche. Karịsịa n'ebe oyi na-atụ, adhesives tile nwere ike na-enweta oge oyi na-ekpo ọkụ ugboro ugboro, nke na-etinye ihe ndị dị elu chọrọ na njirimara njikọ ha. HPMC nwere ike inyere adhesives aka ịnọgide na-enwe ike njikọ ha na ike n'okpuru ọnọdụ ndị a.
Ọrụ HPMC na nrapado taịlị nwere ọtụtụ akụkụ, gụnyere ịgbakọ, njide mmiri, imeziwanye ike njikọta, mgbochi-slip na ịgbatị oge oghe. Ọ bụ kpọmkwem n'ihi ihe ndị a magburu onwe ya na HPMC aghọwo ihe mgbakwunye dị mkpa na mpaghara ihe owuwu, karịsịa na ntinye tile. Ojiji ya nwere ike ọ bụghị naanị ịkwalite nrụpụta ihe owuwu, kamakwa hụ nkwụsi ike ogologo oge mgbe ịtọsịrị ya.
