Cilmiga Chetles ma jiraa?

ENTERS EHOSSESTENTE guud ahaan waxay ku milmaan biyaha, taas oo ka mid ah astaamaha ugu muhiimsan. Xoolaha biyaha ee kaynta ee kahortagga ah ee kahortagga ah waa natiijada wax ka badalida kiimikada ee loo sameeyay poly polymer-ka dabiiciga ah. Common cellulose ethers, such as Methyl Cellulose (MC), Hydroxyethyl Cellulose (HEC), Hydroxypropyl Methyl Cellulose (HPMC), and Carboxymethyl Cellulose (CMC), exhibit varying degrees of solubility depending on their specific chemical structures.

Waa tan dulmar guud oo kooban oo ku saabsan jilitaanka biyaha ee qaar ka mid ah anshaxa unugyada caadiga ah ee ka jira:

1. Midka methyl bylulose (MC):
   • Midabka methyl waxay ku milmaysaa biyo qabow, sameynta xalka cad. Xanihu waxay saameyn ku yeelanaysaa heerka methlowlation, oo leh heerar sare oo ah in la beddelo salaan hoose.
2. Hydroxytylyl (HEC):
   • Hydroxytylylyl si aad ah ayuu u milmaayaa biyaha kulul iyo qabow labadaba. Xoolaheedii xalideeda ayaa saameyn ku leh heerkulka.
3. Hydroxypropyl bylule (HPMC):
   • HPMC waxay ku milmaysaa biyo qabow, iyo xaruudihiisu waxay kordhaan heerkulka sare. Tani waxay u oggolaaneysaa astaanta la xakameynayo oo suura gal ah.
4. Kariimka Kariimka ee CarboxyMyl (CMC):
   • Kariimka 'Bostampytyl' ayaa si fudud loogu milmayaa biyaha qabow. Waxay ka dhigan tahay cadeyn, xalka viscous oo leh xasillooni wanaagsan.

Xoolaha biyaha ee kaynta ah ee kanuga ah ee kantaroolka ah waa hanti muhiim ah oo gacan ka geysaneysa adeegsiga baahsan ee codsiyada kala duwan ee warshadaha. Xalka aqueous, polymers-kaan ayaa mari kara hanaanno sida biyo-galeenka, bararka, iyo abuurista filimka, taasoo ka dhigeysa mid qiimo leh qaabab ay ka mid yihiin adhess, jaakad, dawooyinka, dawooyinka, iyo waxyaabaha cuntada lagu sameeyo.

Waxaa muhiim ah in la ogaado in inta ay qodaashaha unugyada ah ay guud ahaan ku milmaan biyaha, xaaladaha gaarka ah ee jilicsanaanta (sida heerkulka iyo feejignaanta) ay ku kala duwanaan karaan iyadoo ku xiran nooca unugyada unugyada iyo heerka beddelka. Soo-saareyaasha iyo qaabeeyayaasha ayaa sida caadiga ah tixgeliya arrimahan marka ay qaabeeyaan alaabada iyo qaabaynta.
