Diyaarinta xalka dahaarka Hydroxypropyl Methylcellulose (HPMC) waa hab aasaasi ah oo lagu sameeyo warshadaha dawooyinka iyo cuntada. HPMC waa polymer si caadi ah loogu isticmaalo qaab-dhismeedka dahaarka sababtoo ah sifooyinka filim sameynta ee aadka u fiican, xasilloonida, iyo iswaafajinta maaddooyinka firfircoon ee kala duwan. Xalalka dahaarka waxaa loo isticmaalaa in lagu bixiyo lakabyo ilaalin ah, lagu xakameeyo astaamaha sii deynta, iyo in lagu hagaajiyo muuqaalka iyo shaqeynta kiniiniyada, kaabsulka, iyo qaababka kale ee qiyaasta adag.
1. Qalabka Loo Baahan Yahay:
Hydroxypropyl Methylcellulose (HPMC)
Dareeraha (badanaa biyo ama isku darka biyaha iyo aalkolada)
Balaastiig-celiye (ikhtiyaar, si loo hagaajiyo dabacsanaanta filimka)
Waxyaabaha kale ee lagu daro (ikhtiyaar ahaan, sida midabeeyayaasha, opacifiers, ama wakiilada ka hortagga tacking)
2. Qalabka Loo Baahan Yahay:
Weel isku qasid ama weel
Walaaq (farsamo ama birlab)
Miisaanka dheelitirka
Isha kuleylinta (haddii loo baahdo)
Shaandhee (haddii loo baahdo si looga saaro burooyinka)
mitirka pH (haddii hagaajinta pH loo baahdo)
Qalabka badbaadada (gacmo-gashiyada, muraayadaha indhaha, jaakadda shaybaarka)
3. Habka:
Tallaabada 1aad: Miisaanka Waxyaabaha ku jira
Cabbir tirada loo baahan yahay ee HPMC adoo isticmaalaya dheelitirka miisaanka. Qadarku wuu kala duwanaan karaa iyadoo ku xiran xoogga la rabo ee xalka dahaarka iyo cabbirka dufcadda.
Haddii aad isticmaaleyso balaastig ama waxyaabo kale oo lagu daro, cabbir tirada loo baahan yahay sidoo kale.
Tallaabada 2: Diyaarinta Dareeraha
Go'aami nooca dareeraha loo isticmaalayo iyadoo lagu saleynayo codsiga iyo waafaqsanaanta maaddooyinka firfircoon.
Haddii aad biyaha u isticmaaleyso dareeraha, hubi inay nadiif tahay oo la sifeeyay ama la dhalaaliyay.
Haddii aad isticmaaleyso isku darka biyaha iyo khamriga, go'aami saamiga ku habboon iyadoo lagu saleynayo milmida HPMC iyo astaamaha la rabo ee xalka dahaarka.
Tallaabada 3: Isku qasidda
Weelka isku darka saar walaaqaha oo ku dar dareeraha.
Ku bilow walaaqidda dareeraha xawaare dhexdhexaad ah.
Si tartiib tartiib ah ugu dar budada HPMC ee hore loo miisaamay dareeraha walaaqaya si aad uga fogaato inay isku ururto.
Sii wad walaaqidda ilaa budada HPMC si isku mid ah loogu kala firdhiyo dareeraha. Hawshani waxay qaadan kartaa waqti, iyadoo ku xiran xoogga HPMC iyo hufnaanta qalabka walaaqidda.
Tallaabada 4: Kuleylinta (haddii loo baahdo)
Haddii HPMC uusan si buuxda ugu milmin heerkulka qolka, kuleylin jilicsan ayaa laga yaabaa inay lagama maarmaan noqoto.
Isku darka kululee inta aad walaaqayso ilaa HPMC uu gebi ahaanba milmo. Ka digtoonow inaadan aad u kululayn, maadaama heerkulka xad-dhaafka ahi uu waxyeelayn karo HPMC ama qaybaha kale ee xalka.
Tallaabada 5: Ku darista Balaastikada iyo Waxyaabaha kale ee lagu daro (haddii ay khuseyso)
Haddii aad isticmaaleyso balaastiig, si tartiib tartiib ah ugu dar xalka inta aad walaaqeyso.
Sidoo kale, ku dar waxyaabaha kale ee lagu daro sida kuwa midabeeya ama kuwa opacifiers-ka marxaladdan.
Tallaabada 6: Hagaajinta pH (haddii loo baahdo)
Hubi pH-ga xalka dahaarka adoo isticmaalaya mitirka pH.
Haddii pH-gu ka baxsan yahay heerka la rabo sababo la xiriira xasillooni ama iswaafajin, hagaaji adigoo ku daraya tiro yar oo xalal aashito ama aasaasi ah si waafaqsan.
Si fiican u walaaq xalka ka dib marka lagu daro kasta oo dib u hubi pH ilaa heerka la rabo la gaaro.
Tallaabada 7: Isku-darka iyo Tijaabada Kama-dambaysta ah
Marka dhammaan qaybaha la isku daro oo si fiican loo isku daro, sii wad walaaqidda dhowr daqiiqo oo dheeraad ah si aad u hubiso inay isku mid yihiin.
Samee baaritaanno tayo oo lagama maarmaan ah sida cabbiraadda viscosity ama kormeerka muuqaalka si aad u ogaato calaamadaha walxaha qashinka ah ama kala-soocidda marxaladda.
Haddii loo baahdo, xalka mari shaandho si aad uga saarto wixii buro ah ee haray ama walxaha aan milmin.
Tallaabada 8: Kaydinta iyo Baakaynta
Xalka dahaarka ee HPMC ee la diyaariyey ku wareeji weelasha kaydinta ee ku habboon, gaar ahaan dhalooyinka galaaska ee amber ama weelasha balaastikada ah ee tayo sare leh.
Ku calaamadee weelasha macluumaadka lagama maarmaanka ah sida lambarka dufcadda, taariikhda diyaarinta, xoogga saarista, iyo xaaladaha kaydinta.
Xalka ku kaydi meel qabow oo qalalan oo laga ilaaliyo iftiinka iyo qoyaanka si loo ilaaliyo xasilloonida iyo cimriga kaydinta.
4. Talooyin iyo Tixgelinno:
Had iyo jeer raac dhaqamada shaybaarka iyo tilmaamaha badbaadada ee wanaagsan marka aad la tacaalayso kiimikooyinka iyo qalabka.
Nadiifinta iyo nadiifinta inta lagu jiro habka diyaarinta si looga fogaado wasakhowga.
Tijaabi iswaafajinta xalka dahaarka leh substrate-ka loogu talagalay (kiniiniyada, kaabsulka) ka hor inta aan si ballaaran loo isticmaalin.
Samee daraasado xasillooni si loo qiimeeyo waxqabadka muddada dheer iyo xaaladaha kaydinta ee xalka dahaarka.
Diiwaangeli habka diyaarinta oo hayso diiwaannada si loo ilaaliyo tayada iyo u hoggaansanaanta sharciyeed.
