Codsiga magnesium aluminium silicate ee beeraha

Magnesium aluminium silicate waa qaybta ugu muhiimsan ee nano dabiiciga ah - macdanta dhoobada bentonite. Ka dib marka la kala saaro iyo nadiifinta macdanta ceyriinka ah ee bentonite, magnesium aluminium silicate oo nadiif ah ayaa la heli karaa. Magnesium aluminium silicate waa shey jel ah oo aan dabiici ahayn oo leh ganaax aad u fiican, kala firdhisan iyo thixotropy biyaha.

Nooca NF IA magnesium aluminium silicate waa nadiif sare oo magnesium aluminium silicate ka dib nadiifinta, xoqidda iyo daawaynta ultrafine, loogu talagalay budada dareeraha cad ama beige, aan - sun iyo dhadhan lahayn, kama falceliso daawada asalka ah, ma saamayso heerkulka deegaanka , texture jilicsan. Way fududahay in lagu dhex firdhiyo xabagta xal aqueous ah, oo leh xoog kolloikal sare leh iyo awood joojin adag, waana wax-ka-hortagga - dejinta iyo xasilinta biyaha

NF nooca IA isticmaalka aluminium silicate magnesium waxaa loo isticmaali karaa sida dhumuc kaligiis ama lagu daro xanjo xanthan qaabaynta sunta cayayaanka, badbaadinta kharashka alaabta ceeriin.

Hordhac biyo cusub- dhumuc ku salaysan, thixotropic, firdhisan iyo wakiilka laalista ----- magnesium iyo aluminium silicate

(1) Tilmaamaha alaabta ee magnesium iyo aluminium silicate:

Magnesium iyo aluminium silicate waa jel aan organic ahayn oo ay diyaariyeen saponite dabiici ah oo aad loo hagaajiyay iyo montmorillonite. Qaab dhismeedka crystal waa trioctahedral iyo dioctahedral. Guud ahaan caddaan ama caddaan khafiif ah, midab khafiif ah, qallafsanaantu waa yar tahay oo wax yar ayaa simbiriirixan leh. Aan ahayn - sun ah, aan ur lahayn, oo leh astaamo nano Magnesium iyo aluminium silicate waxay si dhakhso ah u fidi karaan marka lagu daro biyaha, samaynta qadar badan oo jel ah oo leh qaabdhismeedka shabakada biyaha. Waxay leedahay sifooyinka kolloidal gaar ah, thixotropy, adsorption, ganaax, dhumucdiisuna, inta badan loo isticmaalo dhumuc, viscosifying, thixotropic, kala firdhiso, wakiilka ganaax.

(2) Sifooyinka alaabta ee magnesium iyo aluminium silicate

1. Xasilooni: Magnesium aluminium silicate jel waa Nanomaterial aan ka samaysan bir ah, macdan aan organic ahayn, oo aan gooyn bakteeriyada iyo mishiinada kuleyliyaha

Burburka burburay, ma baabi'in doono noolaha, muddo dheer - kaydinta muddada-dheer ma xumaato, wax caariyaysi ah, viscosity isma beddelo heerkulka, waxaa lagu fuuqayn karaa biyo deionized heerkulka qolka, ballaadhiyay kolloid la hakiyay. Marka fiirsashada ay tahay 0.5-2.5%, samaynta jel thixotropic hufan ama translucent, baabi'inta habka kuleylka, badbaadinta tamarta, habboon.

1. thixotropy: Magnesium aluminium silicate gel wuxuu leeyahay thixotropy sare oo gaar ah, oo si aad ah uga fiican xabagta kale ee dabiiciga ah iyo kuwa aan noolaha ahayn.
2. Ka-joojin: Isku-duubnaanta habboon ee magnesium iyo aluminium silicate gel biyaha-nidaamka ku salaysan waa la isku xidhi karaa, alaabta budada ah ee la hakiyey, ka joojinta deggan

Dareeraha: ka ilaali walxaha laallay roobabka, ururinta, adkaanta, si ay u diyaargarowga cayayaanku hakiyaan texture lebbiska, fududahay in la isticmaalo, fududahay in la buufiyo, oo aan saamayn wakhtiga xoogga dibadda. Waxqabadkeeda cayrinta ayaa ka badan kuwa kale ee ka mid ah walxaha kale ee ka joojinta noolaha ah.

1. Dhumucda: Marka magnesium aluminium silicate jel iyo colloids organic si wadajir ah loo isticmaalo, saamaynta synergistic waxaa lagu gaari karaa si loo helo waxqabadka ugu fiican. Silicic acid

Magnesium aluminium jel waxa ay caawisaa in la isku duwo viscosity iyo qiyamka dhalid, iyo mawjadaha iyo xasiloonida ayaa ka wanaagsan oo ka dhaqaale badan tan la helay iyada oo la isticmaalayo xabagta organic oo keliya, iyo viscosity waa labanlaab.

1. Waafaqid: Magnesium aluminium silicate gel waxa loo isticmaali karaa anionic iyo non-ionic surfactants surfactants, in yar oo aashito ilaa dhexdhexaad ah

Deggan oo loogu isticmaalo warbaahinta alkaline. Nidaamka elektrolytka oo ay ku jiraan qadar yar oo milix ah, waxay ahaanaysaa mid deggan.

Talooyin ku saabsan waayo-aragnimadawakiilka shaqada ka joojinaya habaynta joojinta

Waxaa guud ahaan lagu talinayaa in magnesium aluminium silicate iyo xanthan xanjo loo diyaariyo qaab jel ka hor, iyo faa'iidooyinka soo socda ayaa lagu daraa geynta dambe:
A. Ka ilaali xabagta xanthan inay isku ururiso kuuskuus yaryar oo aanay si fiican u milmin, samaynta xal xabagta Xanthan oo isku mid ah.
B. Marka ay micilada viscosity viscosity-sare ay dhex maraan qayb ka mid ah shaandhada sander-ka gudaha, way fududahay in la xannibo qaab dhismeedka shaandhada awgeed waxayna kordhiyaan caabbinta iyo hufnaanta carrada.
C. Xanthan xanjo aad u badan ayaa lagu daraa mishiinka cammuudda, iyo xawaaraha toosan ee bacaadka ah iyo is jiid jiidka ayaa sababa jabka qayb ka mid ah qaab dhismeedka silsiladda xanthan, taas oo hoos u dhigaysa saamaynta dhumucda.
D. Haddii isticmaaluhu aanu haysan mishiin xawaarihiisa xiiraya, waxa kaliya lagu dari karaa mishiinka ciidda ama waxa lagu sii diyaarin karaa wakhti dheer si loogu walaaqo xal biyo la diyaariyey.
E. Ku dar xalka biyaha ee qaabka diyaarinta guud ee wax soo saarka viscosity wuxuu noqon karaa kantarool fudud, soo noqnoqoshada viscosity alaabta waa wanaagsan tahay.
F. Marka la ciido, waxa kale oo lagama maarmaan u ah slurry si uu u ilaaliyo viscosity habboon ee ciid, taas oo hagaajin karta waxtarka ciid.
G. Marka laga hadlayo qaar ka mid ah wakiilada joojinta oo ay fududahay in ay soo saaraan xumbo ka dib -xawaare xiirid ka dib marka lagu daro xanjo xanthan, waxaa lagu talinayaa in la gaaro ujeedada kala firdhinta iyo walaaqida marxaladda dambe, goobooyinku aad bay u yaraan doonaan, dabcan. , qaddarka ku habboon ee foamer-ka sidoo kale waa lama huraan. Midda fudud ayaa si toos ah loogu daraa shiididda ciidda, taas oo aan saameyn badan ku yeelanayn xasilloonida wakiilka joojinta. In yar oo kakan, ayaa marka hore lagu daraa khamriga hooyada, ka dib marka lagu daro daroogooyinka asalka ah ee asalka ah ayaa lagu dhejiyaa, oo lagu daraa taangiga kaydinta, ka dibna ku dar xanthan xanjo khamriga hooyada, walaaq si siman ayaa loo duubi karaa.
