Fasalka maalinlaha ah ee Hypromellose waa polymer molecular synthetic oo laga diyaariyey cellulose dabiiciga ah iyadoo la beddelayo kiimiko. Cellulose ether waa nooc ka mid ah cellulose dabiiciga ah. Si ka duwan polymers synthetic, ether cellulose waxaa laga sameeyaa cellulose, macromolecule dabiiciga ah. Sababtoo ah qaabka gaarka ah ee cellulose dabiiciga ah, cellulose lafteedu awood uma laha inay ka falceliso wakiilka etherifying. Laakiin ka dib markii lagu daweeyo wakiilada bararka, bonds hydrogen xoog u dhexeeya iyo gudahood silsiladaha kelli waa la jejebiyey, iyo kooxaha hydroxyl firfircoon waxaa lagu sii daayay galay cellulose alkali fal-celin, ether cellulose waxaa la helay by falcelinta OH kooxda OR kooxda via wakiilka etherification. 200,000 viscosity hypromellose ee loo isticmaalo Max waa budo cad ama huruud ah. Waxaa lagu milmi karaa biyo qabow iyo isku dhafka organic ee dareerayaasha, samaynta xal muuqda oo hufan. Xalka aqueous wuxuu leeyahay dhaqdhaqaaqa dusha sare, daahfurnaanta sare iyo xasilloonida xooggan, iyo kala diristeeda biyaha ma saameynayso pH. Shaambada dhexdeeda, dhumucda gelka qubeyska, saamaynta barafka, timaha, biyaha maqaarka iyo samaynta filim wanaagsan. Iyada oo kor u kaca alaabta ceeriin ee aasaasiga ah, cellulose (daaweeyaha ka-hortagga barafka) ayaa sidoo kale loo isticmaali karaa shaambada iyo qubeyska qubeyska ayaa si weyn u yareyn kara kharashka waxayna gaari karaan natiijooyinka la rabo.
Tilmaamaha iyo faa'iidooyinka maalinlaha ah ee hypromellose HPMC waa: 1) xanaaq, dabacsanaan, 2) xasilloonida pH ballaaran, kaas oo lagu dammaanad qaadi karo inta u dhexeysa pH 3-11,3) qaboojinta la xoojiyay; 4, kordhiso xumbo, xasiloonida xumbo, hagaajin maqaarka; 5, si wax ku ool ah u wanaajiso dareeraha nidaamka. Maalinlaha Hypromellose HPMC waxaa loo isticmaalaa shaambooyinka, maydhista jidhka, nadiifinta wejiga, labeennada, kiriimyada, jelka, toners, timaha qaboojiyaha, alaabta habaynta, daawada cadayga, saabuunta, iyo qubayska xumbo-cayaaraha. Doorka hypromellose HPMC ee codsiyada la isku qurxiyo, waxaa inta badan loo isticmaalaa dhumucdiisuna, xumbo, emulsification deggan, kala firidhsan, adhesion, film-samaynta iyo haynta biyaha ee la isku qurxiyo, alaabta viscosity sare loo isticmaalo dhumucdiisuna, wax soo saarka viscosity hoose waxaa inta badan loo isticmaalaa kala firidhsan hakinta. iyo samaynta filim ee hypromellose HPMC. Hydroxypropyl methyl fibers waxay ku habboon yihiin warshadaha kiimikada maalinlaha ah oo leh viscosity of 100,000,150,000,200,000, marka loo eego qaacido iyaga u gaar ah si ay u doortaan qadarka ku darida ee alaabta guud ahaan waa saddex ilaa shan kun oo meelood oo tilmaamayaasha baakadaha: 25 kg / bac
