Kedu admixture nwere ike melite anwụ ngwa ngwa nke ihe? (HPMC)

Hydroxypropylmethylcellulose (HPMC) bụ ngwakọta nke a na-ejikarị eme ihe na ụlọ ọrụ ihe owuwu, gụnyere ihe nhazi. Ọ bụ ezie na ọ nwere ike ọ gaghị emeziwanye ịdịte aka nke ihe, ọ na-arụ ọrụ dị mkpa n'ịkwalite ihe dị iche iche nke ngwakọta ihe.

1. Okwu mmalite nke hydroxypropyl methylcellulose:

Hydroxypropyl methylcellulose (HPMC) bụ cellulose ether gbanwetụrụ nke sitere na polymers eke. N'ihi ihe ndị pụrụ iche ya, a na-eji ya eme ihe n'ọtụtụ ebe dị ka ihe mgbakwunye na ihe owuwu ụlọ. N'ime ihe, a na-ejikarị HPMC eme ihe dị ka ihe na-ejigide mmiri, thickener, na ihe nkedo. Ọdịdị kemịkal ya na-enyere ya aka ịmepụta ihe nkiri nchebe gburugburu akụkụ ciment, na-emetụta rheological na n'ibu Njirimara nke ihe ngwakọta.

2.The ọrụ nke HPMC na ihe anwụ ngwa ngwa:

Njide mmiri na ịrụ ọrụ:

HPMC na-arụ ọrụ dị ka onye na-ejigide mmiri, na-egbochi oke mmiri n'oge mmalite nke ọgwụgwọ ihe.
Nke a na-eme ka mmiri dị mma na-enyere aka ịnọgide na-arụ ọrụ nke ọma, na-eme ka ọ bụrụ ebe dị mma na nchịkọta nke ihe.

Kwalite adhesion:

Ihe na-emepụta ihe nkiri nke HPMC na-enyere aka melite nrapado n'etiti akụkụ ciment, na-ebute matriks na-ejikọta ọnụ na nke na-adịgide adịgide.

Belata nkewa na ọbara ọgbụgba:

HPMC na-enyere aka belata ihe ize ndụ nke ikewapụ na ọbara ọgbụgba n'ime ngwakọta ihe, na-eme ka e nwee otu ụdị, ngwaahịa njedebe dị mma.

Oge ntọala emelitere:

Ojiji nke HPMC nwere ike imetụta mwube oge nke ihe, si otú na-enye a itule n'etiti workability na accelerated ike mmepe.

Mmetụta dị na akụrụngwa igwe:

Ọ bụ ezie na HPMC n'onwe ya nwere ike ọ gaghị eme ka ọ dị ogologo nke ihe, mmetụta ya na workability na adhesion nwere ike imetụta ihe ndị na-emepụta ihe nke kọnkịta, na-enyere aka ịmepụta ihe ndị siri ike ma na-adịgide adịgide.

3. ndetu na omume kacha mma:

Njikwa usoro onunu ogwu:

Usoro ọgwụgwọ HPMC ziri ezi dị oke mkpa. Ịṅụbiga mmanya ókè nwere ike ịkpata mmetụta ọjọọ, ebe ịṅụbiga mmanya ókè nwere ike ọ gaghị enye nkwalite dị mkpa.

ndakọrịta:

Ekwesịrị ịtụle ndakọrịta na ihe mgbakwunye ihe ndị ọzọ na ihe iji zere mmeghachi omume ọjọọ ọ bụla nke nwere ike imebi njirimara nke ngwakọta ihe.

Usoro ọgwụgwọ:

Ọ bụ ezie na HPMC na-enyere aka idowe mmiri, a ga-eji ụzọ ọgwụgwọ kwesịrị ekwesị mee ihe iji hụ na ọ ga-adị ogologo oge nke ihe ahụ.

Ọ bụ ezie na HPMC abụghị onye na-arụ ọrụ kpọmkwem nke na-eme ka ịdịte aka nke ihe dịkwuo mma, iji ya mee ihe na ngwakọta ihe nwere ike imeziwanye arụmọrụ, adhesion, na ihe ndị ọzọ, si otú a na-eme ka ọ dịkwuo ogologo oge nke ihe owuwu. A ga-atụle HPMC dị ka akụkụ nke usoro agbakwunyere maka imepụta ihe ngwakọta na ihe owuwu iji nweta ihe owuwu na-adịgide adịgide na nke na-adịgide adịgide.
