The composition of enamels
Zibo Tanglian Chemical Equipment Ltd.Co manufacture four series of open-type glass lined reactor、closed-type glass lined reactor、vertical storage vessel、horizontal storage vessel and more than 90 specifications and more than 200 varieties. Various non-standard glass lined reactor、stainless steel pressure reactor and metal carbon steel alloy pressure reactor are designed to produce.
Enamel( inorganic vitreous material) of glass lined reactor: the raw material of enamel include three main categories: chemical raw materials、mineral raw materials and pigment raw materials.
Chemical raw materials are component of enamel, it mainly include: Na2B4O710H2O、NaNo3、Na2Co3、Li2Co3、CaCo3、MgO、ZnO、TiO2、Sb2O3、ZrO2、CoO、NiO、MnO2、Fe2O3 etc.
Pigment raw material refer to the material used to decorate the color of enamel. A total of black、blue、brown、gray、green、pink、white、yellow etc. Enamel is made of the above three raw materials according to a certain proportion(different with the manufacturer), after 1200℃ of high temperature melting and after a sharp cooling into granular or flake borosilicate vitreous. It is divided into bottom glaze、surface glaze、edge glaze and decorative glaze according to the technological properties; according to the different base material,it is divided into steel plate glaze、cast iron glaze、copper enamel、aluminum enamel、stainless steel enamel.
Mineral raw materials is the main component of enamel and occupies a large proportion (different with different manufacturers at home and abroad),which mainly include: feldspar(silicate of alkali metal or alkaline earth metal, commonly used potassium feldspar-K2OAI2O36SiO2)、quartz(mainly composed of silica-SiO2)、clay( aluminosilicate mineral containing water, mainly AI2O36SiO2 and crystalline water)
