Ceramic frit is a very high-quality products in the market has also been a good evaluation glaze, of course, the product is required to enter the market by examining, when you pass this test link is qualified products, greatly accelerates Under a brief segment on the inspection of frit. Frit testing is a very important aspect, he can ensure high security standard ceramic frit glaze, allowing companies to produce high quality and high standards of products, thus opening the market. Here we look at specific. A good high-temperature frit prescription is required is fusible but insoluble (or sparingly soluble). Melting temperature is too high, make effective component lead, boron, fluoride and other play loss; water-soluble high, not only to make the glaze paddle flow variation, but also the loss of target preparation. To ensure fusible, frit prescription alkali metal compound (R2O) alkaline earth metal compound (RO) and the ratio (molar ratio, hereinafter the same) of 1.1 to 1.3 should be manipulated in the meantime, in order to obtain a good quality of the frit, frit Al2O3 amount of which should be manipulated in 0. 2 ~ 0.7mol meantime. Al2O3 and SiO2 ratio of about 1:10, ratio of SiO2 to alkali metal and alkaline earth metal compound (R2O + RO) of from about 2.5 to 4.5 in the meantime. In order to ensure a wide range firing frit and insoluble in water, Jiangxi ceramic glaze, the introduction should be closely manipulate prescription sodium, potassium feldspar try elective, less or no sodium feldspar in high boron frit to boric acid replace all or part of borax; when the clinker contains more B2O3, will cause the water-soluble growth, is normally added to at least twice the amount of B2O3 SiO2, to ensure that the frit is insoluble in water. Zibo Boshan Jinming color glaze frit supply plant is well-known manufacturers, in order to let you know of other aspects of knowledge frit transparent glaze frit production process following analysis: 1. glaze with a lot of material if you do not frit made at the time due to the loss on ignition firing large coefficient of expansion may affect the glaze and pinholes, etc. 2. easy to control the fineness of grinding time and made into frit, glaze easier to control performance 3. Some materials dissolved in water or with a basic, if not made of frit, glaze may affect performance, such as borax, zinc oxide, etc. 4. Some materials, such as carbonated with, clinker burning process can be put in advance in order to emit carbon dioxide, etc. does not affect the glazed flatness, such as potassium nitrate, potassium carbonate, borax.
