Iranian Company Produces 3 Types of Glaze for Pottery Industry
"Our company started working 38 years ago and continues to produce an intermediate product called Lo’ab (glaze). Our company has produced nearly 12,500 tons of products last year,” said Nader Rezayee Manesh, the managing director of the company.
“Ceramic tile factories use glaze for their output. Therefore, we produce a wide range of glazes in grades and with different applications, such as trans and matte, and supply them to our customers,” he added.
“In the last three years, three new products have been released to the market, which replace foreign raw materials in the ceramic tile industry. These products include Shugar (sugar grain glaze), Metroza (third firing glaze) and Granilia (newer sugar grain glaze),” Rezayee Manesh said.
In a relevant development in March, researchers at a technological company in Iran had also managed to produce a 100% hydrophobic polymer powder to reduce the penetration of water into clay and cement structures.
“In this company, we have successfully a hydrophobic additive: A type of this product is used in cement mortars and the other type is used in straw and clay mortars,” Ehsan Sadeghi, Chairman of the Board of Directors of a technology company based at the Science and Technology Park of Kashan University said in an interview with ANA.
“As much as one-twentieth of this additive is added to cement or straw clay mortar in a dry form, and then by adding water, the mortar is ready for use. The surface of the mortar and inside it becomes completely hydrophobic, meaning that water does not penetrate into the cement or clay,” he also said.
Sadeghi said that the powder they have produced in their company is polymer in contrast to other products available in the market. “Some other products also use a hydrophobic cover on the straw and clay surface; A solution that is applied on the surface of straw and clay mortar to make it hydrophobic. This coating loses its hydrophobic properties if it is scratched or is exposed to a sandstorm because it is not a polymer product; Rather, it is the traditional straw and clay mortar,” he explained.
The researcher further highlighted that after adding their powder to the mortar both the surface and the internal part of becomes hydrophobic.
Sadeghi went on to say that the hydrophobic polymer powder is more useful for constructing buildings in the Northern regions of the country where it is usually rainy and humid.
