Hydroxypropyl methylcelculose (hpmc)sisisele esibalulekileyo se-selles enoluhlu olubanzi lwezicelo, ikakhulu kumacandelo olwakhiwo, amayeza, ukutya, njl. Ngokweendlela ezahlukeneyo zokulungisa, i-HPMC inokwahlulwa ibe yintlobo ezinyangwayo eziphathwayo nezingafakwanga.
1. Umahluko kwiinkqubo zemveliso
I-HPMC engafundekiyo
I-HPMC enganyangekiyo ingenzi mpandla yomhlaba okhethekileyo ngexesha lenkqubo, ngoko ke i-hydrophicicity kwaye isolula igcinwa ngokuthe ngqo. Olu hlobo lwe-HPMC lube ngokukhawuleza kwaye luqala ukunyibilikisa emva konxibelelwano namanzi, lubonisa ukwanda ngokukhawuleza kwi-viscofity.
I-HPMC ye-HPMC
I-HPMC ephathwa i-HPMC iya kuba nenkqubo eyongezelelweyo yokudibanisa emva kwemveliso. Izinto eziqhelekileyo zonyango ziyi-acetic acid okanye ezinye iziko elikhethekileyo. Ngolu nyango, kuya kwenziwa ifilimu ye-hydrophobic kumphezulu wamasuntswana e-HPMP. Olu nyango luye lwehlisa inkqubo yayo yokuphelisa, kwaye ihlala iyimfuneko ukwenza ukuba ichithise i-iyunifomu ishukumisa.
2. Umahluko kwiPropathi ye-Solbing
Iimpawu zokugqabhoka kwe-HPMC engafundekiyo
I-HPMC enganyangekiyo iya kuqala ukunyibilikisa kwangoko emva kokunxibelelana namanzi, elungele iimeko ezineemfuno eziphezulu zesantya sokuchitheka. Nangona kunjalo, ukusukela ukupheliswa okukhawulezayo kukwenza i-Asglomerates, isantya sokutya kunye nokuvuselela iyunifomu kufuneka silawulwe ngononophelo.
Iimpawu zokuNyikisa i-HPMC ephathwayo ye-HPMC
Ukudibana kumphezulu wamasuntswana athathwe phaya we-HPMC kuthatha ixesha lokunyibilikisa okanye ukutshabalalisa, ke ixesha lokuchitheka lide, lihlala imizuzu eliqela ukuya kwimizuzu elishumi. Lo uyilo luphela kukwenza i-AGGGGOMUMICHELOKO kwaye ilungele ngokukodwa kwimigangatho efuna ukuqina okukhulu okanye umgangatho wamanzi ontsonkothileyo ngexesha lenkqubo yokongeza.
3. Umahluko kwiimpawu ze-viscosity
I-HPMC ephathwa i-HPMC ayiyi kukhulula i-viscofity kwangoko ngaphambi kokupheliswa, ngelixa i-HPMC engachazwanga ngokukhawuleza yandisa umzobo wenkqubo. Ke ngoko, kwiimeko apho uVilosity kufuneka ahlengahlengiswe ngokuthe ngcembe okanye inkqubo kufuneka ilawulwe, uhlobo lokuphathwa komhlaba lunenzuzo.
4. Umahluko kwiimeko ezikhoyo
I-HPMC-I-HPMC ye-HPMC
Ilungele imiboniso efuna ukuchithwa ngokukhawuleza kunye nokwenza kwangoko, njengabakhali beearhente zokukhathalela kwangoko kwintsimi yamayeza okanye kwizinto ezikhawulezayo kwishishini lokutya.
Ikwaqhuba kakuhle kwezinye izifundo zelebhu okanye imveliso yamancinci enolawulo olungqongqo lokulandelelana kokondla.
I-HPMC ye-HPMC
Isetyenziswe ngokubanzi kumzi-mveliso wokwakha, umzekelo, kudaka owomileyo, ekubambeleleni kwethayile, iingubo kunye nezinye iimveliso. Kulula ukusasaza kwaye ungazinzi mthethweni, ezilungele ngakumbi iimeko zokwakha zoomatshini.
Ikwasetyenziswa nakumalungiselelo athile amachiza afuna ukukhutshwa okuzinzileyo okanye izongezelelo zokutya ezilawula umyinge wokuchitha.
I-5. Ixabiso kunye neyantlukwano yokugcina
Ixabiso lemveliso le-HPMC eliphathwayo lingaphezulu nangaphaya kwento enganyangekiyo, eboniswe ngumahluko kwixabiso lentengiso. Ukongeza, uhlobo lonyango lophathekileyo lunokukhulula okukhuselekileyo kwaye lube neemfuno ezisezantsi ze-subred kunye neqondo lokushisa lendawo yogcino, ngelixa uhlobo olunganyangekiyo lungaphezulu kwaye lufuna iimeko zokugcina izinto ezingqongqo.
I-6. Isiseko
Xa ukhetha i-HPMC, abasebenzisi kufuneka bathathele ingqalelo la manqaku alandelayo ngokweemfuno ezithile:
Ngaba ireyithi yokuchithwa ibalulekile?
Iimfuno zenqanaba lokukhula kwe-viscosity.
Nokuba iindlela zokutya kunye nokudibanisa kulula ukwenza i-Asggomerates.
Inkqubo yeshishini yesicelo ekujoliswe kulo kunye neemfuno zomsebenzi wokugqibela zemveliso.
Ukuphathwa komhlaba kunye nokunganyangekiI-HPMCzineempawu zazo. Lowo wangaphambili uphucula lula ukusetyenziswa nokuzinza ngokusebenza ngokutshintsha indlela yokuziphatha, kwaye kufanelekile ukuveliswa kwemveliso enkulu; Eli lokugqibela ligcina izinga lokupheliswa kwexabiso eliphezulu kwaye lifaneleke ngakumbi kwiShemikhali yeChemical Chemikhali efuna ireyithi yexabiso eliphezulu. Ukukhetha koluphi uhlobo kufuneka kudityaniswe nemeko ethile yesicelo, iimeko zenkqubo kunye nohlahlo-lwabiwo mali lweendleko.
