Biyo la'aanta Hydroxypropyl Methylcellulose (HPMC) waxay caadi ahaan ku lug leedahay ku qasidda dareeraha ku habboon ama kala firdhinta si loo gaaro xoogga la doonayo.HPMC waa polymer si weyn loogu isticmaalo dawooyinka, isqurxinta, iyo alaabta cuntada sababta oo ah dhumucdeeda, xasilinta, iyo sifooyinka samaynta filimada.Dilution inta badan waa lagama maarmaan si loo hagaajiyo viscosity ama diiradda codsiyada gaarka ah.
Fahamka HPMC:
Qaabdhismeedka Kiimikada: HPMC waa polymer-synthetic semi-synthetic oo laga soo qaatay cellulose.Waxay ka kooban tahay unugyo gulukoos oo soo noqnoqda oo leh hydroxypropyl iyo kooxaha methyl.
Guryaha: HPMC waxay ku milmay biyaha iyo qaar ka mid ah dareerayaasha organic sida khamriga iyo acetone.Miisaankeedu wuxuu ku xiran yahay arrimo ay ka mid yihiin miisaanka unugyada, heerka beddelka, iyo heerkulka.
Waxyaalaha ay tahay in la tixgeliyo ka hor inta aan la qasin:
Shuruudaha Xoog-saarista: Go'aami diiradda la rabo ee HPMC ee codsigaaga.Tani way kala duwanaan kartaa iyada oo ku xidhan arrimo ay ka mid yihiin viscosity, guryaha samaynta filimada, iyo waafaqsanaanta maaddooyinka kale.
Xulashada Xalka: Dooro dareere ama wakiil kala firdhiye oo ku habboon codsigaaga oo ku habboon HPMC.Walxaha caadiga ah waxaa ka mid ah biyaha, khamriga (tusaale, ethanol), glycols (tusaale, propylene glycol), iyo dareerayaasha organic (tusaale, acetone).
Heerkulka: Qaar ka mid ah buundooyinka HPMC waxay u baahan karaan xaalado heerkul gaar ah si loo milmo.Hubi in heerkulka dareeruhu uu ku habboon yahay isku darka iyo kala dirida hufan.
Tallaabooyinka lagu baabi'iyo HPMC:
Qalabka Diyaari:
Nadiifi oo engegan weelasha isku dhafka ah, ulaha walaaqaya, iyo qalabka cabbiraadda si looga hortago faddaraynta.
Hubi hawo habboon haddii aad isticmaasho dareerayaasha organic si aad uga fogaato khataraha neefsashada.
Xisaabi Saamiga Kala-saarista:
Go'aanso cadadka loo baahan yahay ee HPMC iyo dareeraha ku salaysan u-fiirsashada kama dambaysta ah ee la rabo.
Si sax ah u cabbir qiyaasta loo baahan yahay ee budada HPMC adoo isticmaalaya dheellitir ama qaaddo cabbir.
Cabbir mugga dareeraha habboon ee ku salaysan saamiga milanka la xisaabiyay.
Habka isku dhafka:
Ku bilow inaad ku darto dareeraha weelka isku darka ah.
Si tartiib ah ugu daadi budada HPMC dareeraha adoo walaaqaya si joogto ah si aad uga hortagto isku-duubnida.
Sii wad walaaq ilaa budada HPMC ay si buuxda ugu kala firdhiso dareeraha.
Ikhtiyaar ahaan, waxaad isticmaali kartaa kicinta farsamada ama sonication si kor loogu qaado kala firdhinta.
Oggolow kala diri:
Isku darka ha istaago in muddo ah si loo hubiyo in ay si buuxda u milmaan qaybaha HPMC.Waqtiga kala diriddu wuu kala duwanaan karaa iyadoo ku xiran arrimo ay ka mid yihiin heerkulka iyo kacsanaanta.
Hubinta tayada
Hubi viscosity, hufnaanta, iyo isku midnimada xalka HPMC ee la badhxay.Hagaaji fiirsashada ama saamiga dareeraha haddii loo baahdo.
Kaydinta iyo Maaraynta:
Ku kaydi xalka HPMC ee la badhxay weel nadiif ah oo si adag u xidhan si looga hortago faddaraynta iyo uumiga.
Raac talooyinka kaydinta ee ay bixiso soo saaraha, gaar ahaan ku saabsan heerkulka iyo soo-gaadhista iftiinka.
Talooyin iyo taxaddarrada badbaadada:
Gear Badbaadada: Xidho qalabka ilaalinta shakhsi ahaaneed ee ku habboon (PPE) sida galoofyada iyo muraayadaha badbaadada, gaar ahaan marka aad gacanta ku hayso dareerayaasha organic.
Ka Fogow Wasakhaynta: Ka ilaali dhammaan qalabka iyo weelasha nadiifka ah si aad uga hortagto faddaraynta, taas oo saamayn karta tayada xalka la qasi karo.
Xakamaynta heerkulka: Ilaali xaaladaha heerkulka joogtada ah inta lagu jiro habka milanka si loo hubiyo natiijooyinka dib loo soo saari karo.
Tijaabinta Waafaqid: Samee tijaabooyinka waafaqsanaanta maaddooyinka kale ama waxyaabaha lagu daro kuwaas oo lagu dari doono xalka HPMC ee la qasi karo si looga fogaado arrimaha qaabaynta.
Kala-saarista HPMC waxay ku lug leedahay tixgelinta taxaddarka leh ee arrimaha ay ka midka yihiin shuruudaha fiirsashada, xulashada dareeraha, iyo farsamooyinka isku dhafka.Adigoo raacaya hababka saxda ah iyo taxaddarrada badbaadada, waxaad si guul leh u diyaarin kartaa xalalka HPMC ee la qasi karo ee ku habboon baahiyahaaga gaarka ah.Had iyo jeer la tasho tilmaamaha soo saaraha oo samee tijaabooyinka iswaafajinta lagama maarmaanka ah si aad u hubiso waxqabadka ugu fiican iyo tayada alaabta.
