Saddex siyaabood oo lagu garto tayada hydroxypropyl methylrcellulose

Hydroxypropylykylcellellase waa polymer caan ah oo caan ku ah oo samaysa xalka cad oo deggan oo si weyn loogu isticmaalo dawooyinka, cuntada iyo warshadaha dhismaha iyo dhismaha. Waa shey ceyriska ku saleysan ee ion-inic-ka ee hagaajinaya xidhitaanka iyo astaamaha isku-darka ee sheyga ugu dambeeya. Si loo hubiyo in waxqabadka tayada sare ee hydroxypropylyl methylcelrelosuse, badeecadu waxay u baahan tahay in la tijaabiyo oo uu u qalmo kahor isticmaalka. Qodobkan, waxaan ka wada hadli doonnaa saddex dariiqo oo lagu kalsoonaan karo oo loo sheego tayada ay ku leeyihiin tayada hydroxypropyl methylcelrelose.

1. Tijaabada viscosity

Muuqaalka hydroxypropylkyl methylcelrellase waa halbeeg muhiim ah si loo go'aamiyo tayadeeda. Viscosity waa iska caabbinta dareeraha lagu qulqulayo waxaana lagu cabiraa centipoise (CPS) ama MPA.S. Muuqaalka caymiska hydroxypropyl methylcelrellose wuxuu ku kala duwan yahay miisaanka molokalka iyo heerka beddelka. Heerka sare ee beddelka, hoos u dhaca aragtida sheyga.

Si loo tijaabiyo aragtida hydroxypropylyl methylcelrelosuse, milaan wax yar oo ka mid ah sheyga biyaha ku jira oo isticmaal muuqaal si aad u cabbirto aragtida xalka. Muuqaalka xalka xalka waa inuu kujiraa tirada lagu taliyay ee ay bixiso alaab-qeybiyeyaasha. Alaabada tayada leh ee tayada leh ee hydroxypropyl pluylcelrellose sheyga waa inuu lahaadaa viskcosity joogto ah, taas oo ah tilmaanta daahirnimo iyo cabir isku mid ah.

2. Tijaabada Beddelka

Heerka beddelka waxaa loola jeedaa saamiga tirada kooxaha hydroxyl ee ku yaal cudurka cellulose ee lagu beddelay hydroxypropyl ama kooxaha methyl. Heerka beddelka ayaa ah tilmaame ku saabsan daahirka badeecada, heerka sare ee heerka beddelka, nadiifinta sheyga. Waxyaabaha tayada leh ee tayada sare leh ee hydroxypropylylulose alaabtu waa inay lahaadaan heer sare oo beddelaad ah.

Si loo tijaabiyo heerka beddelka, shatration waxaa lagu sameeyaa sodium hydrochide iyo hydrochloric acid. Go'aaminta qadarka hydroxide sodium ah ee loo baahan yahay si looga takhaluso hydroxypropylyl methylcelrelolose oo xisaabi heerka badalka oo adeegsanaya qaaciddada soo socota:

Heerka Beddelka =

Heerka beddelka waa inuu kujiraa tirada lagu taliyay ee uu bixiyay alaab-qeybiyeyaasha wax soo saarka. Heerka beddelka badalka tayada tayo sare leh ee hydroxypropylyl methylcelrellosase alaabtu waa inay ku dhexjiraan baaxadda lagu taliyay.

3. Tijaabada Slube

Xoolaha jilicsan ee hydroxypropyl methylcelrelose waa halbeeg kale oo muhiim ah oo go'aaminaya tayadeeda. Alaabta waa in si fudud loogu xaliyaa biyaha oo aan sameysan buro ama gels. Waxyaabaha tayada tayo sare leh ee hydroxypropylylcellesulose alaabtu waa inay si dhakhso ah u milaan si dhakhso ah oo siman.

Si loo sameeyo tijaabada xaruuda, milaan qadar yar oo shey ah oo biyo ah oo walaaq xalka ilaa gabi ahaanba la kala diray. Xalku waa inuu ahaadaa mid cad oo ka madax bannaan buruq ama gels. Haddii sheygu si fudud u milmayo ama qaabeeyo buro ama gels, waxay calaamad u noqon kartaa tayada liidata.

Gabagabadii, hydroxypropyl methylcelrelolose waa shey ceyriin oo qiimo leh oo loo isticmaalo warshadaha kala duwan. Si loo hubiyo tayada sare ee sheyga, viscosity, beddelka iyo tijaabooyinka xaruudaha ayaa la sameeyaa. Imtixaannadaani waxay gacan ka geysan doonaan inay si cad u fahmaan astaamaha sheyga iyo gacan ka geysashada kala sooca tayadeeda. Hydroxypropylpyl methylcelrellase waxay leedahay viscosis, heerka sare ee beddelka, oo si dhakhso leh uguna kala diro biyaha.
