Bentonite is used as a binder of molding compounds in the manufacture of molds for mechanized and automated lines for the production of castings of ferrous and non-ferrous alloys.<\/p>\n

Bentonite from \u00abthe 10th Khutor\u00bb deposit is a high-tensile and has a high thermal resistance indicator, which is its undeniable advantage in comparison with bentonite from other deposits for the production of steel castings.<\/p>\n

\u00abBentonite of Khakassia\u00bb Ltd. manufactures\u00a0Bentonite powders for foundry sands of the following grades<\/strong>: \u00a0P1\u04221\u0410, P1\u04222\u0410, \u00a0P2\u04221\u0410 in accordance with GOST 28177-89.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n

Specialists of our Company developed and introduced into batch production a new complex molding material with nonstick additives for the production of iron castings in sand-clay forms:\u00a0bentonite powder \u00abBentakarb\u00bb<\/strong>.<\/p>\n

Bentonite powder is a powder mixture of bentonite of P1T1A grade and special carbon-containing components with different ratio of mineral and organic elements.<\/p>\n

\u00abBentonite of Khakassia\u00bb Ltd. manufactures several brands of bentonite powder in accordance with the requirements of TU 2164-003-01424676-2014:\u00a0Bentakarb-\u0410<\/strong>\u00a0(the ratio of bentonite and carbon-containing components is 80\/20),\u00a0Bentakarb-B (70\/30)<\/strong>,\u00a0Bentakarb-V (60\/40)<\/strong>.<\/p>\n

Materials of the grade\u00a0Bentakarb-\u0410\u0421<\/strong>,\u00a0Bentakarb-B\u0421<\/strong>\u00a0and\u00a0Bentakarb-V\u0421<\/strong>\u00a0are distinguished by higher nonstick performance.<\/p>\n

\u00abBentakarb\u00bb<\/strong>\u00a0compositions have a number of distinctive operational and technological properties:<\/p>\n

    \n
  • exclusion of pre-mixing operations of additives directly in the foundry production;<\/li>\n
  • reduction of bunker and dosage systems in the preparation of the mixtures;<\/li>\n
  • high binding and non-stick properties;<\/li>\n
  • optimization and stabilization of the properties of heap molding sand of the mixture during the process of refreshment by components, regardless of the time of the analysis of its composition;<\/li>\n
  • reduction of the total consumption of molding materials (bentonite and nonstick carbon additive);<\/li>\n
  • provision of qualitative distribution of components in the moldable mixture;<\/li>\n
  • improvement of breaking of castings from the molds;<\/li>\n
  • exception of spontaneous combustion of carbon-containing nonstick additives, their oxidation and as consequence the loss of efficiency during transportation, warehousing and in supply silos;<\/li>\n
  • optimization of logistics issues.<\/li>\n<\/ul>\n

    The application technology of the new binder does not require the modernization of technological equipment. The additive may be put into the moldable mixture both in dry form or aqueous suspension.<\/p>\n
