FAQS
HPMC amaHydroxypropyl methylcellulose(Magaca INN: Hypromellose), oo sidoo kale loo fududeeyay sida hydroxypropyl methylcellulose (HPMC), waa nooc ka mid ah cellulose-ka aan-ionic ahayn ee ether-ka isku qasan. Waa semi-synthetic, aan firfircoonayn, polymer viscoelastic ah. Hydroxypropyl methylcellulose waxaa si weyn loogu isticmaalaa dhismaha, cuntada, daawada, iyo warshadaha kale.

Solubility: Ku milmay biyaha iyo qaar ka mid ah dareerayaasha, sida saamiga ku habboon ethanol / biyaha, propanol / biyaha, iwm. Xalka aqueous wuxuu leeyahay hawlo korka ah. Iyada oo hufnaanta sare iyo waxqabadka xasilloon, heerkulka jel ee qeexitaannada kala duwan ayaa ka duwan, milanka isbeddelka leh ee viscosity, viscosity ayaa hooseeya iyo milanka ayaa ka weyn. Waxqabadka HPMC oo leh tilmaamo kala duwan ayaa leh farqi gaar ah. Kala dirida HPMC ee biyaha ma saamayso qiimaha PH.
HPMC waxaa soo saaray Longou:

Hydroxypropyl methylcellulose (HPMC) waa ethers cellulose kuwaas oo lahaa kooxaha hydroxyl ee silsiladda cellulose oo lagu beddelay methoxy ama kooxda hydroxypropyl.It waxaa lagu sameeyaa etherification gaar ah oo ah cellulose suuf aadka saafiga ah oo hoos yimaada xaaladaha alkaline. Sannadihii ugu dambeeyay, HPMC, sida isku-darka shaqaynaya, ayaa inta badan door ka ciyaarasee haynta biyaha iyo dhumucyada warshadaha dhismaha oo si weyn loogu isticmaalohoobiyeyaasha drymix, sida koolada tile, grouts, malaasta, suufka gidaarka, is barbardhig, hoobiye dahaarka iyo iwm.
Caadi ahaan, budada putty, viscosity eeHPMCayaa ku filan qiyaastii 70,000 ilaa 80,000. Diirada ugu weyni waxay tahay waxqabadkeeda xajinta biyaha, halka saamaynta dhumucdu ay tahay mid yar. Hoobiyaha, shuruudaha loogu talagalayHPMCway sarreeyaan, oo mawjaduhu waxay u baahan yihiin inay noqdaan ilaa 150,000, taas oo hubin karta inay si fiican ugu shaqeyso hoobiye sibidhka. Dabcan, budada putty, ilaa inta waxqabadka haynta biyaha ee HPMC uu wanaagsan yahay, xitaa haddii viscosity uu hooseeyo (70,000 ilaa 80,000), waa la aqbali karaa. Si kastaba ha ahaatee, hoobiye sibidhka, waxa aad u fiican in la doorto HPMC oo leh maqaar weyn (in ka badan 100,000), sababtoo ah saameynteeda xajinta biyaha ayaa aad muhiim ugu ah xaaladdan.
Dhibaatada ka saarista budada putty inta badan waxay kuxirantahay tayada kaalshiyamka hydroxide oo wax yar kuma laha HPMC. Haddii maadada kaalshiyamka ee kalsiyum hydroxide ay hooseyso ama saamiga CaO iyo Ca (OH) 2 ay tahay mid aan habooneyn, waxay keeni kartaa in budada suufka ah ay hoos u dhacdo. Marka la eego saamaynta HPMC, waxay inta badan ka muuqataa waxqabadkeeda haynta biyaha. Haddii waxqabadka haynta biyaha ee HPMC ay liidato, waxa kale oo laga yaabaa inay saamayn gaar ah ku yeelato soo-buxinta budada putty.
Shuruudaha loo baahan yahay isticmaalka budada putty waa kuwo aad u hooseeya. 100,000 viscosity ayaa ku filan. Furaha ayaa ah in la helo sifooyin wanaagsan oo lagu hayo biyaha. Marka la eego hoobiye, shuruuduhu aad bay u sarreeyaan oo viscosity sare ayaa loo baahan yahay, 150,000 oo badeecada waxay leedahay saameyn wanaagsan.
(1) Warshadaha dhismaha: Sida wakiilka biyaha-haynta iyo dib-u-dejiya hoobiye sibidhka, waxay ka dhigaysaa hoobiye mid la shubi karo. Isticmaal malaastaan, gypsum, budada suufka ah ama qalabka kale ee dhismaha sida koollo ahaan si aad u wanaajiso ku habboonaanta oo aad u dheereyso wakhtiga qalliinka. Waxaa loo isticmaali karaa in lagu dhejiyo dhoobada dhoobada, marmar, qurxinta balaastiigga, koollada xoojinta, iyo dhimista qadarka sibidhka. Hantida biyaha haynta ee HPMC waxay ka hortagtaa slurryku inuu dillaaco sababtoo ah si degdeg ah u engegan ka dib marka la xoqo waxayna kordhisaa xoogga.
(2) Warshadaha wax soo saarka dhoobada: si weyn loogu isticmaalo sida xabagyada samaynta alaabta dhoobada.h ka dib marka la adkeeyo.
(3) Warshadaha dahaarka: Sida dhumuc weyn, kala firdhisan iyo xasilinta warshadaha daahan, waxa ay leedahay milmi wanaagsan ee biyaha ama dareerayaasha organic.
(4) Daabacaadda Khadka: Sida dhumuclaha, kala firdhisa iyo xasilinta warshadaha khadka, waxay leedahay milmi wanaagsan oo biyaha ama dareeraha organic.
(5) Caagag: sida samaynta wakiilka sii daynta, jilcisa, saliidaha, iwm.
(6) Polyvinyl chloride: Sida ku kala firdhisan wax soo saarka chloride polyvinyl, waa kaaliyaha ugu weyn ee diyaarinta PVC by polymerization hakinta.
(7) Kuwo kale: Alaabtan waxa kale oo si weyn loogu isticmaalaa hargaha, alaabta waraaqaha, ilaalinta khudradda iyo khudaarta, iyo warshadaha dunta.
