Habka kala dirida HPMC Hydroxypropyl methylcellulose

Hydroxypropyl methylcellulose, oo sidoo kale loo yaqaan HPMC, waa ether nonionic cellulose ah oo laga helo suuf la safeeyey, maaddo polymer dabiici ah, iyada oo loo marayo taxane kiimiko ah. Waa budo cad ama huruud ah oo si fudud ugu milmay biyaha. Aynu ka hadalno habka kala dirida hydroxypropyl methylcellulose.

1. Hydroxypropyl methylcellulose waxaa inta badan loo isticmaalaa wax lagu daro budada, hoobiye iyo xabagta. Lagu daro hoobiye sibidhka, waxa loo isticmaali karaa sidii wakiilka biyaha haynta iyo dib u dhigista si loo kordhiyo bamamka; waxaa lagu daraa budada putty iyo xabagta, waxaa loo isticmaali karaa sida wax lagu xidho. Si loo wanaajiyo faafitaanka loona kordhiyo wakhtiga hawlgalka, waxaanu tusaale ahaan u soo qaadanaynaa Qingquan Cellulose si aanu u sharaxno habka kala dirida hydroxypropyl methylcellulose.

2. Hydroxypropyl methylcellulose caadiga ah ayaa marka hore walaaqaya oo lagu kala firdhiyey biyo kulul, ka dibna lagu daraa biyo qabow, walaaq oo la qaboojiyey si ay u milmaan;

Gaar ahaan: qaado 1/5-1/3 qiyaasta biyaha kulul ee loo baahan yahay, walaaq ilaa alaabta lagu daray ay si buuxda u bararaan, ka dibna ku dar qaybta haray ee biyaha kulul, kuwaas oo noqon kara biyo qabow ama xitaa biyo baraf ah, oo walaaq heerkulka ku habboon (10 ° C) ilaa si buuxda u milmay.

3. Habka qoynta dareeraha dabiiciga ah:

Ku kala firdhi hydroxypropyl methylcellulose dareere organic ah ama ku qoysi dareere organic ah, ka dibna ku dar ama ku dar biyo qabow si ay si fiican u milaan. Walxaha dabiiciga ah wuxuu noqon karaa ethanol, ethylene glycol, iwm.

4. Haddii agglomeration ama duub ay dhacdo inta lagu jiro kala diri, sababtoo ah walaaqdu kuma filna ama qaabka caadiga ah ayaa si toos ah loogu daraa biyo qabow. Halkaa marka ay marayso, dhaqso u walaaq.

5. Haddii xumbo ay abuurmaan inta lagu jiro kala dirida, waxaa lagu dayn karaa 2-12 saacadood (waqtiga gaarka ah wuxuu ku xiran yahay joogteynta xalka) ama laga saaro iyada oo la nadiifinayo, cadaadis, iwm, ama lagu daro qadar habboon oo ah wakiilka xumbo-sameynta.

Ka taxadaritaan

Hydroxypropyl methylcellulose waxay u qaybsantaa noocyo aayar u milma iyo noocyo kala diris ah. Isla markiiba hydroxypropyl methylcellulose si toos ah ayaa loogu milmi karaa biyo qabow.
