Sodium metasilicate pentahydrate yopanga ceramic slurry kupanga

Kupanga ma grouting ndi njira yachikhalidwe yomwe imagwiritsidwa ntchito pokonza zosoweka za ceramic. Kwa okhazikika kupanga zida ndi kufa, khalidwe la akusowekapo

Zimatsimikiziridwa makamaka ndi katundu wamatope. The slurry kukwaniritsa zofunika ndondomeko adzakhala fluidity wabwino, bata zina ndi yoyenera

Thixotropy, filterability yabwino, madzi otsika, thupi lobiriwira lomwe linapangidwa lili ndi mphamvu zokwanira kuti zithandizire kutulutsa komanso kutulutsa thovu, etc., ndi kutuluka.

Slurry yokhala ndi ntchito yabwino idzagwiritsidwa ntchito kuti zitsimikizire kuyenda bwino mu payipi, kugawa mosavuta kumadera osiyanasiyana a nkhungu, komanso kosavuta kukhazikika,

Pangani mbali zonse za thupi lobiriwira yunifolomu. Kuonjezera electrolyte mumatope ndiyo njira yaikulu yowonjezeramo madzi ake

Ndi galasi lamadzi, sodium carbonate, phosphate, sodium humate, sodium tannate, sodium polyacrylate, ndi zina zotero

Galasi ndiye chinthu chomwe chimagwiritsidwa ntchito kwambiri, koma pali zovuta zina zomwe zimagwiritsidwa ntchito, monga kusinthasintha kwakukulu kwa kapangidwe kake, muyeso wovuta, kusungirako ndi mayendedwe, ndi zina zambiri.

Sodium metasilicate ndi ufa woyera wokhala ndi modulus wa 1 [(nSiO2)/n (Na2O), wopangidwa ndi sodium silicate ndi caustic soda.

Crystal, yokhala ndi mamolekyu 5 amadzi a krustalo, malo osungunuka 72.2 ℃, amasungunuka mosavuta m'madzi, 1% yankho lamadzi PH=12.5, lamchere pang'ono

Chifukwa chake imakhala ndi dilution effect ndikuti imatha kukulitsa kuchuluka kwamphamvu kwa micelle m'matope, motero imakulitsa makulidwe ndi ξ magetsi.

The repulsion mphamvu pakati particles ndi kuchuluka; Pa nthawi yomweyi, anion silicate yomwe ili mu sodium metasilicate ndi yofanana ndi Ca2 +

Mg 2 + ma ion owopsa amapanga zinthu zosasungunuka, amalimbikitsa kusinthana kwa N a +, amachepetsa kukhuthala kwamatope, ndikuwonjezera madzimadzi.

Sodium metasilicate ili ndi mphamvu yotchinga yolimba ku pH mtengo wamatope, ndipo anion silicate yomwe ili mmenemo imawonjezera chigawo cha dongo.

Kuphatikiza pa kachulukidwe kawo, ndikosavuta kuchitapo kanthu ndi Ca2 + ndi Mg2 + ions yoyipa m'matope kuti apange mchere wosasungunuka ndikulimbikitsa kusinthana kwa Na ions.

Imatha kupanga dongo lochulukirapo ndikuwongolera matope: matope akawonjezedwa ku nkhungu kuti apange,

Ndikosavuta kuchitapo kanthu ndi gypsum, ndipo imatha kutulutsa mwachangu ndikuwumitsa, kuti muchepetse nthawi yopanga zobiriwira. Sodium metasilicate nthawi zambiri imachokera ku kuchuluka kwa dongo

0.3% ~ 0.5% ogwira nawo ntchito amawonjezedwa, omwe sali oyenera kupanga grouting wamba, komanso oyenera kukakamiza kupanga ma grouting. Ndi yabwino kugwiritsa ntchito komanso yotsika mtengo

Kuchita bwino kwa dilution.

Pa nthawi yomweyi, sodium metasilicate ndi yosavuta kusakaniza ndi zosakaniza zina zomwe zimagwiritsidwa ntchito kawirikawiri monga phulusa la soda, phosphate, sodium humate kuti apange njira yothetsera dilution.

Guluu ali ndi ntchito yabwinoko kuposa degumming agent. Pakadali pano, sodium metasilicate ndiye chinthu chachikulu chomwe chimagulitsidwa pamsika

Zimafunika zosakaniza.

Kuphatikiza apo, sodium metasilicate imakhala ndi kunyowetsa mwamphamvu, emulsifying ndi saponifying pa zinthu zamafuta, ndipo imakhala ndi magwiridwe antchito amphamvu,

Amagwiritsidwa ntchito kwambiri pokonzekera zotsukira zosiyanasiyana. Kuphatikiza apo, imagwiritsidwanso ntchito kwambiri pakupanga nsalu, kupanga mapepala, kuchotsa mafuta ndi mafakitale ena
