Waxyaalaha Saameeya Waxsoosaarka Viscosity HPMC:

Miisaanka Molecular:
Miisaanka molecular eeHPMCwaxay si weyn u saamaysaa viscositykeeda. Polymers-ka miisaankoodu sarreeyo ayaa guud ahaan muujiya viscosity sare sababtoo ah isku-xidhka silsiladda oo kordhay. Si kastaba ha noqotee, miisaanka unugyadu aad u sarreeyo wuxuu u horseedi karaa caqabado xagga diyaarinta iyo habaynta xalka. Sidaa darteed, xulashada miisaanka miisaanka kelli ee habboon ayaa muhiim u ah isu dheellitirka shuruudaha viscosity-ka oo leh tixgalin la taaban karo.

Heerka Beddelka (DS):
Heerka beddelka waxa loola jeedaa celceliska tirada hydroxypropyl iyo methoxy beddelka unugga anhydroglucose ee silsiladda cellulose. Qiimayaasha sare ee DS caadi ahaan waxay keenaan viscosity sare sababtoo ah qulqulka biyaha iyo isdhexgalka silsiladda oo kordhay. Si kastaba ha ahaatee, beddelka xad-dhaafka ah wuxuu u horseedi karaa hoos u dhaca milanka iyo u janjeersiga. Sidaa darteed, tayaynta DS waxay lama huraan u tahay gaaritaanka viscosity-ka la rabo iyadoo la ilaalinayo milanka iyo habsocodka.

Xoog-saarista:
Viscosity HPMC waxay si toos ah ugu dhigantaa fiirsigeeda xalka. Marka fiirsashada polymerka ay korodho, tirada silsiladaha polymer ee mugga cutubkiiba sidoo kale way korodhaa, taasoo horseedaysa isku-xidhka silsiladda oo la xoojiyey iyo viscosity sare. Si kastaba ha ahaatee, marka la eego aadka u sarreeya, viscosity ayaa laga yaabaa inuu sarreeyo ama xitaa hoos u dhaco sababtoo ah isdhexgalka polymer-polymer iyo samaynta jel ee ugu dambeyntii. Sidaa darteed, wanaajinta diiradda ayaa muhiim u ah gaaritaanka viscosity-ka la rabo iyada oo aan waxyeello loo geysan xasilloonida xalka.

Heerkulka:
Heerkulka ayaa saameyn weyn ku leh viscosity ee xalalka HPMC. Guud ahaan, viscosity wuxuu hoos u dhacaa heerkulka sii kordhaya sababtoo ah isdhexgalka polymer-polymer oo yaraaday iyo dhaqdhaqaaqa unugyada oo la xoojiyay. Si kastaba ha ahaatee, saameyntani way kala duwanaan kartaa iyadoo ku xiran arrimo ay ka mid yihiin fiirsashada polymer, miisaanka kelli, iyo isdhexgalka gaarka ah ee dareerayaasha ama waxyaabaha lagu daro. Dareenka heerkulka waa in la tixgeliyaa marka la samaynayo alaabada HPMC ku salaysan si loo hubiyo waxqabadka joogtada ah ee xaaladaha heerkulka kala duwan.

pH:
pH ee xalku wuxuu saameeyaa viscosity HPMC iyada oo loo marayo saamaynta ay ku leedahay milanka polymer iyo isku-dhafka. HPMC waa kan ugu milmay oo muujiya viscosity-ka ugu sarreeya ee waxoogaa aashito ah iyo pH dhexdhexaad ah. Ka leexashada kala duwanaanshahan pH waxay u horseedi kartaa hoos u dhaca milanka iyo viscosity sababtoo ah isbeddelada qaabaynta polymerka iyo isdhexgalka molecules dareeraha ah. Sidaa darteed, ilaalinta xaaladaha pH ee ugu fiican ayaa lama huraan u ah sare u qaadista viscosity HPMC ee xalka.

Waxyaabaha lagu daro:
Waxyaabo kala duwan, sida milix, surfactants, iyo co-solvents, waxay saameyn karaan viscosity HPMC iyagoo bedelaya guryaha xalinta iyo isdhexgalka polymer-kalka. Tusaale ahaan, milixdu waxay keeni kartaa kor u qaadida viscosity iyada oo loo marayo saamaynta milixda, halka surfactants ay saameyn ku yeelan karaan xiisadda dusha sare iyo milanka polymer. Isku-dubbaridyadu waxay wax ka bedeli karaan polarity dareeraha waxayna kor u qaadaan milanka polymerka iyo viscosity. Si kastaba ha ahaatee, waafaqid iyo is dhexgalka ka dhexeeya HPMC iyo waxyaabaha lagu daro waa in si taxadar leh loo qiimeeyaa si looga fogaado saamaynta aan loo baahnayn ee ku saabsan viscosity iyo waxqabadka alaabta.

waa polymer-ka badan ee si weyn loogu isticmaalo dawooyinka, cuntada, dhismaha, iyo warshadaha qurxinta. Viscosity ee xalalka HPMC ayaa door muhiim ah ka ciyaara go'aaminta waxqabadkeeda codsiyada kala duwan. Fahamka arrimaha saameeya wax soo saarka viscosity HPMC, oo ay ku jiraan miisaanka kelli, heerka beddelka, xoogga saarista, heerkulka, pH, iyo waxyaabaha lagu daro, ayaa lama huraan u ah hagaajinta shaqadeeda iyo waxqabadkeeda. Iyagoo si taxadir leh u faragalinaya arrimahan, daneeyayaasha waxay habayn karaan guryaha HPMC si ay u buuxiyaan shuruudaha codsiga gaarka ah si wax ku ool ah. Cilmi baaris dheeraad ah oo lagu sameeyo isdhexgalka ka dhexeeya arrimahan ayaa sii wadi doona horumarinta fahamkeena iyo ka faa'iidaysiga HPMC ee qaybaha warshadaha kala duwan.
