Kedu ọrụ HPMC na-egwu na ịkwalite adresion na njigide mmiri nke ntụ ntụ?

1. NKWUP
Hydroxypyl Methylcelllose (hpmc) bụ nke ethrugul e nwere mkpụrụ osisi na-ewu ewu. Na ntinye nke usety ntụ, HPMC na-arụ ọrụ dị mkpa na njikọta ya na njigide mmiri, nke na-emetụta arụmọrụ owu na nsonaazụ nke ntụ ntụ.

2. Njirimara nke HPMC
HPMC bụ ihe na-abụghị nke ionic cellulose nwetara site na ngbanwe kemịkal nke sellose eke. A na-ewebata Metoxy na Hydropopopopoxy Otu n'ime usoro molecular, nke na-eme HPMC nwere ezigbo mmiri sogbality na akụrụngwa na-akpụ akpụ. Na mgbakwunye, HPMC nwekwara nnukwu kemịkalụ na iguzogide hydrolysis hydrolysis, nke na-eme ya n'ọtụtụ ebe.

HPMC nwere ezigbo ọrụ, nke nwere ike belata mgbochi esemokwu dị n'etiti ntụ ntụ na elu ya ma mee ka akwara nke ihe ahụ. Mgbe Pur 20 na-akpọtụrụ mkpụrụ, HPMC nwere ike ịkwalite ụdị nke mkpụrụ osisi ma kpọtụrụ mkpụrụ osisi dị elu, si otú a na-eme ka ndọnye nke ntụ ntụ.

Ihe Njirimara 3.2 Njirimara
HPMC nwere ike ịmalite ngwọta carfụl na ngwọta. Ka mmiri ahụ na-elopụ, HPMC ga-etolite ihe nkiri siri ike ma na-agbanwe agbanwe na elu nke mkpụrụ. Ihe nkiri a nwere ike ọ bụghị naanị ịkwalite njikọ n'etiti ntụ ntụ na mkpụrụ, kamakwa na-egbochi nrụgide nke mkpụrụ, site na igbochi ịgbagọ agbagọ ma wụsa nke ntụ oyi putty.

HPMC nwere ezigbo mmiri ngwanchi ma nwee ike igbu oge na-agbanwe agbanwe na ntụ ntụ. Ngwongwo a dị ezigbo mkpa n'oge usoro owuwu, n'ihi na eji ntụ ntụ chọrọ mmiri dị mma maka mmeghachi omume na mgbapụta oge ihicha. HPMC nwere ike idobe mmiri, yabụ na ntụ ntụ ntụ ntụ nwere ike ịnọgide na-eme ihe ndozi dị mma ogologo oge, si otú a na-eme ka ihe owuwu ewu ewu site na ihicha ngwa ngwa.

4.2 Mụbality nke nkesa mmiri
Ihe owuwu nke Hpmc guzobere na ntụ ntụ ntụ nwere ike kesaa mmiri ma zere nsogbu nke oke mmiri ma ọ bụ ezughi oke. Nke a na - ekesa mmiri a na - abụghị naanị na - arụ ọrụ panty ntụ ntụ, kamakwa na - eme ka ịchafụ ọnụ ma na - eme ka nsogbu kwụsịlata n'oge ihicha.

4.3 Meziwanye njide mmiri
HPMC na-agbanwe iru mmiri nke ube site na ịmakụ ma tọhapụ mmiri, ka ọ nwee ike ịnọgide na-ebe mmiri dị mma n'okpuru ọnọdụ owuwu. Ndobe mmiri a ọ bụghị naanị ogologo oge na-emeghe oge ntụ ntụ, kamakwa na-abawanye ọrụ na-arụ ọrụ iji nwayọọ na-eme ka ọrụ zuru oke ma belata mkpa maka ngwa ọrụ na ndozi.

5. Ihe omuma atu
Na ngwa, ịta nke HPMC na ntụ ntụ na-abụkarị n'etiti 0.1% na 0.5%, na itinye uche dị iche iche dabere na usoro ntụ ntụ ma na-arụ ọrụ. Dịka ọmụmaatụ, mgbe ị na-ewu na elu okpomọkụ ma ọ bụ ebe a na-ewuru ya, enwere ike ịbawanye nke ọma iji melite njigide mmiri na ike mgbochi nke ntụ ntụ. N'aka nke ọzọ, n'oge a chọrọ nkwado adhesion dị elu, arụmọrụ nke na-eme ka enwe ike ịmịpụta site na ịbawanye ọdịnaya hpmc.

Ngwa nke HPMC na Pusi mma osisi na-eme ka nchekwa ya na njigide mmiri ya. A na-enweta akụkụ abụọ a site na elu ọrụ, ihe ngosi na-akpụ akpụ na-emepụta nke Hpmc, na njigide mmiri ya, na-egbu oge ihicha na ikike njigide mmiri. Mmeghe nke HPMC ọ bụghị naanị ka mma owuwe ihe owuwu nke ntụ ntụ, kamakwa na-eme ka ọ dị mma na-arụ ọrụ, ma na-enye nkwado ọrụ teknụzụ a ga-enwe maka mmepe nke ụlọ ịchọ mma.
