Kugwiritsa ntchito magnesium aluminium silicate muulimi

Magnesium aluminium silicate Ndiye gawo lalikulu la nano - nele dongo la mchere wa bentonite. Pambuyo kagulu ndi kuyeretsa kwa Bentonite Raw Ore, magnesium alumninum ukhondo wa chiyero osiyanasiyana ungapezeke. Magnesium aluminium slika ndi mankhwala osokoneza bongo okhala ndi kuyimitsidwa kwabwino kwambiri, kubalalitsidwa ndi thixotropy madzi.

NF mtundu IA magnesium aluminiyamu silicate ndi mkulu chiyero magnesium aluminium silicate pambuyo kuyeretsedwa, kuvula ndi ultrafine akupera mankhwala, kwa beige woyera kapena beige madzi ufa, sanali - poizoni ndi zoipa, sachita ndi mankhwala oyambirira, samakhudzidwa ndi kutentha kwa chilengedwe. , zofewa. Ndiosavuta kumwazikana kukhala guluu mu njira yamadzimadzi, yokhala ndi mphamvu zambiri za colloidal komanso kuyimitsidwa mwamphamvu, ndipo ndi anti-yokhazikitsira wothandizira komanso wokhazikika pamadzi-oyimitsidwa mankhwala ophera tizilombo.

Nf mtundu ia kugwiritsa ntchito magnesium aluminium silicate Itha kugwiritsidwa ntchito ngati thickiner yokha kapena yophatikizidwa ndi xanthan chingamu m'mastictotion, kupulumutsa ndalama zopangira.

1. 1."Gawo la mankhwala ophera tizilombo" magnesium aluminium silicate product

(1) Kukhazikika kwabwino;

(2) Kuyimitsidwa kwabwino kwambiri komanso kuchita bwino kwa thixotropic;

(3) Wantchito wabwino wa Rheagical, thickening wothandizira, kuyimitsidwa ndi emulsion stabilizer;

(4) binder ndi disintegrator wa particles olimba;

(5) thixotropic regulator ya kuyimitsidwa dongosolo

2. 2.Kugwiritsa ntchito pokonzekera mankhwala ophera tizilombo

Kuyamba kwa madzi atsopano-ozikidwa pa thickening, thixotropic, dispersing and suspending agent --- magnesium ndi aluminium silicate

(1) Makhalidwe a magnesium ndi aluminium silicate:

Magnesium ndi aluminiyamu silicate ndi gel osakaniza okonzedwa ndi osinthidwa kwambiri zachilengedwe saponite ndi montmorillonite. Kapangidwe ka kristalo ndi trioctahedral ndi dioctahedral. Nthawi zambiri zoyera kapena zoyera zoyera, mawonekedwe abwino, kuuma kumakhala kochepa komanso koterera pang'ono. Zopanda-zowopsa, zopanda fungo, zokhala ndi mawonekedwe a nano. Magnesium ndi aluminiyamu silicate amatha kukulirakulira akawonjezeredwa m'madzi, ndikupanga gel ochulukirapo okhala ndi maukonde amadzi. Iwo ali wapadera colloidal katundu, thixotropy, adsorption, kuyimitsidwa, thickening, nthawi zambiri ntchito monga thickening, viscosifying, thixotropic, kubalalitsidwa, kuyimitsidwa wothandizira.

(2) Zogulitsa za magnesium ndi aluminium silicate

1. Kukhazikika: Magnesium aluminiyamu silicate gel ndi sanali -

Dulani kuwonongeka kuwonongeka, sikudzakokoloka ndi tizilombo tating'onoting'ono, kusungirako nthawi yaitali sikuwonongeka, palibe mildew, mamasukidwe amadzimadzi sasintha ndi kutentha, akhoza kuthiridwa ndi madzi osungunuka kutentha, kuwonjezeredwa ku colloids yoyimitsidwa. Pamene ndende ndi 0,5-2.5%, mapangidwe mandala kapena translucent thixotropic gel osakaniza, kuthetsa Kutentha ndondomeko, mphamvu yopulumutsa, yabwino.

1. thixotropy: Magnesium zotayidwa silicate gel osakaniza ali wapadera mkulu thixotropy, kwambiri kuposa organic ndi zomatira inorganic.
2. Kuyimitsidwa: Mu ndende yoyenera ya magnesium ndi aluminium silicate gel osakaniza madzi - zotengera dongosolo akhoza zomangira, inaimitsidwa ufa zipangizo, khola kuyimitsidwa

Zamadzimadzi: kupewa inaimitsidwa zinthu mpweya, kudzikundikira, kuumitsa, kuti mankhwala kuyimitsidwa kuyimitsidwa yunifolomu kapangidwe kake, yosavuta kugwiritsa ntchito, yosavuta kupopera, osati anakhudzidwa ndi kunja mphamvu nthawi. Kuyimitsidwa kwake kumaposa kwa ma organic and inorganic suspension agents.

1. Kukula: Pamene gel osakaniza a magnesium aluminium silicate ndi organic colloids amagwiritsidwa ntchito palimodzi, mphamvu ya synergistic imatha kukwaniritsidwa kuti igwire bwino ntchito. Silicic acid

Magnesium aluminiyamu gel osakaniza amathandiza kulumikiza mamasukidwe akayendedwe ndi mtengo zokolola, ndi mamasukidwe akayendedwe ndi bata ndi bwino ndi ndalama zambiri kuposa amene angapezeke pogwiritsa organic guluu yekha, ndi mamasukidwe akayendedwe kuwirikiza kawiri.

1. Kugwirizana: Magnesium aluminiyamu silicate gel osakaniza angagwiritsidwe ntchito ndi anionic ndi sanali - ionic amphoteric surfactants, mu acidic pang'ono kwa sing'anga.

Wokhazikika kuti agwiritsidwe ntchito pazambiri zamchere. Mu dongosolo la electrolyte lomwe lili ndi mchere pang'ono, limakhala lokhazikika.

Malingaliro pazomwe zachitika kuyimitsa wothandizira Poyimitsidwa

Nthawi zambiri tikulimbikitsidwa kuti magnesium aluminium silicate ndi xanthan chingamu zikonzekeredwe kukhala pre-gel mawonekedwe, ndipo maubwino otsatirawa amawonjezedwa pakutumiza pambuyo pake:
A. Pewani guluu wa xanthan kuti lisasunthike kukhala timagulu tating'onoting'ono komanso osasungunuka bwino, kupanga njira yokhazikika yokhazikika ya Xanthan glue.
B. Pamene mkulu - mamasukidwe akayendedwe viscous micelles kudutsa mbali ya fyuluta ya m'nyumba sander, ndi zosavuta kutsekereza chifukwa cha dongosolo fyuluta ndi kuonjezera kukana ndi mchenga dzuwa.
C. Kuchulukirachulukira kwa xanthan chingamu kumawonjezedwa ku mphero ya mchenga, ndipo kuthamanga kwakukulu kwa mchenga ndi mikangano kumayambitsa kusweka kwa gawo la unyolo wa xanthan, potero kumachepetsa kukhuthala.
D. Ngati wosuta alibe mkulu-liwiro kukameta ubweya makina, akhoza kungowonjezera pa mphero mchenga kapena kukonzekera pasadakhale kwa nthawi yaitali kusonkhezera mu madzi okonzedwa kale.
E. Add madzi njira mu mawonekedwe a ambiri kukonzekera mankhwala mamasukidwe akayendedwe akhoza kukhala yosavuta kulamulira, mankhwala mamasukidwe akayendedwe repeatability ndi zabwino.
F. Pamene mchenga, m'pofunikanso kuti slurry kusunga kukhuthala koyenera kwa mchenga, zomwe zingathandize kuti mchenga ukhale wabwino.
G. Koma ena kuyimitsidwa wothandizira kuti n'zosavuta kutulutsa thovu pambuyo mkulu-liwiro kukameta ubweya pambuyo kuwonjezera xanthan chingamu, Ndi bwino kukwaniritsa cholinga kubalalitsidwa ndi kuvunda mwa kuyambitsa mu siteji kenako, thovu adzakhala zochepa kwambiri, ndithudi. , kuchuluka koyenera kwa defoamer nakonso ndikofunikira. Chosavuta chimawonjezedwa mwachindunji pakupera kwa mchenga, zomwe sizikhala ndi mphamvu zambiri pa kukhazikika kwa wothandizira kuyimitsidwa. A pang'ono zovuta, choyamba chikufanana mu mowa mayi, pambuyo choyambirira zina mankhwala ndi mchenga, mu thanki yosungirako, ndiyeno kuwonjezera xanthan chingamu mayi mowa, chipwirikiti wogawana akhoza mmatumba.
