Hydroxypropyl Cellulose ee Dalabka Putty Darbiga

Hordhaca Hydroxypropyl Cellulose

Sifooyinka Kiimikada ee Hydroxypropyl Cellulose
Caddaan ama in yar oo huruud ah ama granules cawl ama budo suuf ah. Aan ur lahayn oo aan dhadhamin, guban, heerkulbeeg. Waxay ku milmaan biyaha si hufan ama caano leh xal kolloidal viscous ah. Ku milma ethanol, aan lagu milmi karin ether. Aan ku milmin biyaha ka sarreeya 38 ℃.
Isticmaalka Hydroxypropyl Cellulose
Emulsifier, wakiilka filimka, kolloid ilaalin ah, xasiliye, wakiilka hakin, dhumuc. Dalka Japan, 70% ka mid ah waxa loo isticmaalaa dawada sida kiniinka xidhadhka iyo dahaarka filimada. Waxay u isticmaashaa warshadaha dawooyinka sidii xidhidhyo iyo wakiil filim samaynta, waxyaalaha la isku qurxiyo, dahaarka, warshadaha khadka sida wakiilka samaynta filimada, kala firdhiya, xasiliya, dhumuc, iwm.
1, loo isticmaalo sida xabagta: gudaha farmashiyaha, alaabtan waxaa inta badan loo isticmaalaa sida binder ah, sida kiniiniyada Kiimikada, granules, Qurub ganaax ee binder, guud ahaan 1-5% miisaanka wakiilka, dooro RT-L ama RT-J nooca.
2, oo loo isticmaalo sida alaabta daahan filimka ee kiniiniyada, HPC waxay leedahay sifooyin filim-samayn heer sare ah, filimka soo baxay waa mid adag oo laastikada ah, waxaa lagu barbar dhigi karaa balaastikada, adoo ku daraya wakiilada kale ee ka hortagga heerkulka, waxay sii wanaajin kartaa waxqabadka filimka. Guud ahaan isticmaal nooca RT-L.
3. Waxaa loo isticmaalaa sidii dhumuc weyn ee elixir, lagu daro ee saabuunta iyo stabilizer of emulsion. Guud ahaan nooca RT-M ayaa la isticmaalaa.
4. Waxaa loo isticmaali karaa sida wax qalfoofka loogu talagalay diyaarinta ee kaniiniyada sii-daynta lafaha, kaniiniyada sii-daynta joogtada ah iyo kiniiniyada sii-daynta double-lakabka, iyo RT-M nooca guud ahaan loo isticmaalo.
5. Waxaa loo isticmaali karaa sida wakiilka gel ee munaasabadda ethanol iyo sida saldhigga cadarka.

Habka diyaarinta ee Hydroxypropyl Cellulose
(1) Daaweynta cellulose leh alkali iyo propylene chloride;
(2) Daawaynta saxarka alwaax ama saxarka lignin oo leh fiirsashada sare ee sodium hydroxide impregnation si loo soo saaro xalalka cellulose alkaline, shaandhaynta iyo cadaadiska xalkan si looga saaro sodium hydroxide-ka xad-dhaafka ah, ka dibna ka sii falcelinta propylene oxide si loo helo.

Macluumaadka shirkadda

Waxyaalaha ay shirkadu soo dejiso iyo wax-soo-saarka dhoofinta ugu badan waxaa ka mid ah

( 1 ) Polymers: Polymersation waa habka ay unugyada soo noqnoqda ee ka samaysan polymer ay si wadajir ah ugu xiran yihiin bonds covalent. Polymers waxay ka jiri karaan gobolo kala duwan iyadoo ku xiran wajiga, qaabka iyo habeynta silsiladahooda molecular. Labada dawladood ee ugu waaweyn waa amorphous iyo crystalline. Polymers inta badan waxay ku jiraan qaab semi-crystalline ah kaas oo wejiyada amorphous iyo crystalline ay wada nool yihiin.

( 2 ) Walxaha Ceyriinka ah ee Dabiiciga ah : Waxay leedahay adeegsi ballaaran oo kala duwan, kuwaas oo loo qaybin karo saddex qaybood: marka hore, waxaa loo isticmaalaa sida alaabta ceeriin ee wax soo saarka kiimikada polymer, ie, monomers for polymerisation reactions; labaad, waxa loo isticmaalaa sida alaabta ceeriin ee warshadaha kale ee kiimikaad organic, oo ay ku jiraan alaabta kiimikada wanaagsan; iyo saddexaad, waxa loo isticmaalaa sida dareere ah, qaboojiye, antifreeze, iyo adsorbent gaas. Warshadaha kiimikada dabiiciga ah ee aasaasiga ah ayaa saldhig u ah horumarinta wax soo saarka alaabada kiimikada ee kala duwan, waa qaybta ugu muhiimsan ee qaabka casriga ah ee warshadaha casriga ah.
