Saamaynta DS ee Tayada karboxymethyl cellulose

Heerka Beddelka (DS) waa halbeeg muhiim ah oo si weyn u saameeya tayada iyo waxqabadka Carboxymethyl Cellulose (CMC). DS waxa ay tilmaamaysaa celceliska tirada kooxaha karboksymethyl ee lagu beddelay unug kasta oo anhydroglucose ah oo ah laf dhabarta cellulose. Qiimaha DS wuxuu saameeyaa sifooyin kala duwan oo CMC ah, oo ay ku jiraan milmaheeda, viscosity, awoodda haynta biyaha, iyo habdhaqanka rheological. Waa kan sida DS u saameeyo tayada CMC:

1. Soluble:

• DS hoose: CMC oo leh DS hooseeya waxay u egtahay inay ku milmi yartahay biyaha sababtoo ah kooxo karboxymethyl ah oo yar oo diyaar u ah ionization. Tani waxay keeni kartaa heerar kala dirid oo gaabis ah iyo waqtiyo fuuq-baxa oo dheer.
• Sare DS: CMC oo leh DS sare ayaa aad ugu milmay biyaha, maadaama tirada korodhay ee kooxaha karboxymethyl ay kor u qaadayso ionization iyo kala firdhinta silsiladaha polymer. Tani waxay keenaysaa kala diri degdeg ah iyo hagaajinta guryaha fuuqbaxa.

2. Viscosity:

• DS hoose: CMC oo leh DS hoose wuxuu caadi ahaan muujiyaa viscosity hoose marka la barbar dhigo darajooyinka DS sare. Kooxaha karboksymethyl ee yaraa waxay keenaan isdhexgalka ionic oo yaraada iyo ururrada silsiladaha polymer daciifka ah, taasoo horseedda mawjadaha hoose.
• Sare DS: Heerarka sare ee DS CMC waxay u muuqdaan inay leeyihiin viscosity sare sababtoo ah ionization kordhay iyo isdhexgalka silsiladda polymer oo xooggan. Tirada badan ee kooxaha karboksymethyl waxay kor u qaadaan isku xidhka haydaroojiinka iyo isku-duubnida, taasoo keentay xalal sare oo viscosity ah.

3. Haysashada Biyaha:

• DS hoose: CMC oo leh DS hoose waxa laga yaabaa inay hoos u dhigto awoodda haynta biyaha marka la barbar dhigo darajooyinka DS sare. Kooxaha karboksymethyl ee yar ayaa xaddidaya tirada goobaha la heli karo ee isku xidhka iyo nuugista biyaha, taas oo keenta sii haynta biyaha hoose.
• Sare DS: Heerarka sare ee DS CMC waxay caadi ahaan muujiyaan guryaha haynta biyaha ee sarreeya sababtoo ah tirada korodhay ee kooxaha karboxymethyl ee diyaar u ah fuuq-celinta. Tani waxay kor u qaadaysaa awoodda polymerka ee ah in uu nuugo oo uu hayo biyaha, hagaajinta waxqabadkiisa sida dhumuclaha, xidhaha, ama xakamaynta qoyaanka.

4. Dhaqanka Rheological:

• DS hoose: CMC oo leh DS hoose wuxuu u janjeeraa inuu yeesho dabeecad socodka Newtonian oo badan, oo leh viscosity ka madax banaan heerka xiirid. Tani waxay ka dhigaysaa mid ku habboon codsiyada u baahan viscosity deggan oo ka sarreeya heerar kala duwan oo heerar xiiran, sida diyaarinta cuntada.
• Sare DS: Heerarka sare ee DS CMC waxaa laga yaabaa inay muujiyaan dabeecado caag ah oo khafiif ah ama xiirid, halkaasoo viscosity hoos u dhaco iyadoo la kordhinayo heerka xiirid. Gurigani wuxuu faa'iido u leeyahay codsiyada u baahan fududaynta bamgareynta, buufinta, ama faafinta, sida rinjiga ama alaabta daryeelka shakhsi ahaaneed.

5. Xasilooni iyo Iswaafajin:

• DS hoose: CMC oo leh DS hoose ayaa laga yaabaa inay soo bandhigto xasillooni ka wanaagsan iyo la jaanqaadka maaddooyinka kale ee qaabaynta sababtoo ah ionization hoose iyo isdhexgalka daciifka ah. Tani waxay ka hortagi kartaa kala goynta wejiga, roobabka, ama arrimaha kale ee xasiloonida ee nidaamyada adag.
• Sare DS: Heerarka sare ee DS CMC waxaa laga yaabaa inay aad ugu nugul yihiin gelation ama kala-soocidda wejiga ee xalalka xoogga leh ama heerkul sarreeya sababtoo ah isdhexgalka polymer oo xooggan. Diyaarinta taxadarka leh iyo habaynta ayaa loo baahan yahay si loo hubiyo xasiloonida iyo ku-habboonka xaaladahan oo kale.

Darajada Beddelka (DS) waxay si weyn u saamaysaa tayada, waxqabadka, iyo ku habboonaanta Carboxymethyl Cellulose (CMC) ee codsiyada kala duwan. Fahamka xidhiidhka ka dhexeeya guryaha DS iyo CMC ayaa muhiim u ah doorashada darajada ku habboon si loo buuxiyo shuruudaha qaabaynta ee gaarka ah iyo shuruudaha waxqabadka.
