Sidee Polydadmac (poly diallyldimethylammonium chloride)

Maxaad u doorataa Polydadmac?

Maaddaama wax-soo-saarka Shiinaha ay muddo dheer gacanta ku hayeen alaabta ceeriin ee fiber-ka-cagaaran, iyo fiilooyinka geedaha geedaha yaryar ay gaaban yihiin, oo ay ku jiraan waxyaabo badan oo heterocytes ah, saxarka cawska wuxuu leeyahay haynta hoose iyo sifeynta biyaha liidata ee habka waraaqaha.

Polydadmac waxay hagaajin kartaa dhibaatada hoos u dhigista iyo sifeynta biyaha liidata ee habka waraaqaha, hagaajinta wax soo saarka iyo ka faa'iidaysiga alaabta ceeriin, waxay yaraynaysaa qiimaha tan waraaqaha iyo wasakhowga deegaanka.Polydadmac sidoo kale waxay hagaajin kartaa waxqabadka sifaynta biyaha ee saxarka iyo samaynta xaashida.

Maqaalkani waxa uu baadhayaa adsorption, haynta, iyo sifaynta sifaynta ee Polydadmac oo leh miisaanyo unugyo kala duwan sida wax lagu daro saxarka cawsduur-cadaysan, oo hel gabagabada soo socota.

1.Adsorption of Polydadmac on saxarka Reed

Miisaanka molecular ee yar yar ee Polydadmac, ayaa sii weynaan doona hoos u dhaca heerka xayeysiiska ee kordhinta qadarka kaalmada, taas oo laga yaabo inay sabab u tahay xaqiiqda ah in miisaanka molecular yar ee Polydadmac, awoodda weyn ee lagu qabto anions.Inta yar ee polydadmac ayaa looga baahan yahay isla qadarka anion ee nidaamka saturated.

2. Saamaynta shaandhaynta ee Polydadmac

Iyada oo la kordhinayo qiyaasta polydadmac, shahaadada sifaynta waxay u egtahay inay hoos u dhacdo ka dibna korodho, iyo shahaadada sifaynta waxay ku dhowdahay ama xitaa ka badan tahay tan bannaan marka qadarka wax lagu daro uu gaaro oo ka sarreeyo 0.8%.Tani waxay ka dhigan tahay in Polydadmac aad u badan aysan caawin karin sifeynta, laakiin waxay ka sii daraysaa sifaynta biyaha ee saxarka.Taasi waxay ka dhigan tahay miisaanka kala duwan ee Polydadmac ayaa si fiican u shaandhayn u yeeshay ka hor intaanay buuxin kharashka xun ee dusha sare ee fiber-ka.

3.Retention saamaynta Polydadmac

Marka qiyaasta Polydadmac ay korodho, fiirsashada biyaha cad ee saxarka cawska ayaa si tartiib tartiib ah hoos u dhacaya marka hore, ka dibna mar kale ayaa kordha.Baaritaankaani wuxuu muujinayaa in ku darida polydadmac ee saxarka cawsdu ay si weyn u wanaajin karto haynta fiilooyinka gaaban iyo qaybaha wanaagsan iyo ka faa'iidaysiga alaabta ceeriin, waxayna yaraynaysaa culayska dareeraha.Waxaa la ogaaday in qiyaasta ugu fiican ee polydadmac aysan saameyn ku yeelan miisaankooda kelli;Inta yar ee miisaanka kelli ee polydadmac, ayaa ka sii wanagsan saamaynta sii haynta.Laakiin kala duwanaanshuhu ma cadda, oo polydadmac miisaankoodu kala duwan yahay waxay leeyihiin saameyn wanaagsan oo ku haynta dusha sare ee fiilooyinka saxarka ka hor intaysan dhicin eedeymo xun.

Gabagabo:

1.Polydadmac oo leh miisaanyo kala duwan oo kala duwan ayaa leh shaandhayn wanaagsan iyo saameyn ku haynta saxarka cawska;
2. Saamaynta shaandhaynta iyo xajinta ee ka wanaagsan ayaa la gaadhay marka cadadka polydadmac ee la isticmaalay ay ka yar tahay kharashka xun ee dusha sare ee fiilooyinka saxarka buuxa;

3.Miisaanka molecular Low polydadmac has good retention effect.Miisaanka molecular High wuxuu leeyahay saamayn shaandhayn wanaagsan.Si kastaba ha ahaatee, ma jiro farqi weyn oo ku saabsan waxtarkeeda ee caawinta sifeynta iyo sii-haynta.
