Hydroxypropylkyl methylcelrelose, oo sidoo kale loo yaqaan HPMC, waa ether unugyo unugyo ah oo aan laga heley oo laga soo qaatay suufka lagu safeeyo, ashyaa'da polymer dabiiciga ah, oo loo marayo hababka kiimikada dabiiciga ah. Waa budo cad ama waxyar oo huruud ah oo si fudud u milmiya biyaha. Aynu kahadalno habka kala-baxa ee ku-xadgudubka hydroxypropyl methylcelrelose.
1. Waxaa lagu daray hoobiyeynta sibidhka, waxaa loo istcimaali karaa sidii wakiil biyo-haynta biyaha iyo dib-u-riixitaan si loo kordhiyo korontada; Waxaa lagu daray budada nudaha iyo koollada, waxaa loo isticmaali karaa sidii xayndaab. Si loo wanaajiyo fiditaanka iyo waqtiga hawlgalka, waxaan qaadnaa Qingquulose celquulose tusaale ahaan si aan u sharaxno habka kala-baxa ee hydroxypropyl methylcellosuse.
2.
Gaar ahaan: Qaado 1 / 5-1
3. Qaabka loo yaqaan 'soltent' ee loo yaqaan 'soltend'
Kala kala firdhin hyroxypropyl methylrcelrelose methertelrellose methertellelrcellelrcellelrcelrenose in uu ku qoro dareeraha dabiiciga ah ama ku qoro dareeraha dabiiciga ah, ka dibna ku dar ama ku dar biyo qabow si aad si fiican u baabi'iso. Ururka dabiiciga ah ee dabiiciga ah wuxuu noqon karaa ethanol, glycol glycol, iwm.
4. Haddii agglomation ama duubitaan ay dhacdo inta lagu gudajiro kala diridda, sababta oo ah in walaaqyadu aysan ku filnayn ama qaabka caadiga ah ayaa si toos ah loogu daray biyaha qabow. Halkaan, si dhakhso leh u walaaq.
5. Haddii xumbo laga soo saaro inta lagu jiro kala diridda, waxaa looga tagi karaa 2-12 saacadood (waqtiga gaarka ah waxay kuxirantahay joogtaynta xalka) ama ay ka saaraan faafin, iwm.
Ka taxadaritaan
Hydroxypropyl methylcelrellase waxay u qaybsan tahay noocyo-diirran oo deg deg ah. Degdegga degdegga ah ee hydroxypropylsylrcellellase waxaa si toos ah loogu kala diri karaa biyo qabow.
