ORIENTATION FOR SPECIALIZED PROCESSING OF KAOLIN, PRODUCTION OF EXPORT PRODUCTS
Vietnam is one of the countries with significant kaolin reserves, typically distributed into small mines throughout localities from North to South. However, selection and processing technology is still outdated, so every year our country still has to import high-quality kaolin to serve the production of paper and high-end ceramics. Up to now, most of Vietnam's Kaolin is exported as raw materials, which both do not have high economic value and are a waste of national resources.
With the existing advantage of a modern German-Czech technology line invested in 2009, right after the covid-19 epidemic was controlled, QBBK renovated and upgraded equipment for kaolin deep processing. Although the quality of Kaolin ore from Bac Ly mine is not ideal, we have successfully produced two ultra-clean and ultra-fine product lines K85 and K95 for ceramic production and high-end applications. Samples sent for analysis at Keramik-Institut; Meißen - Germany, had very positive results and was recognized as "Meeting European export standards". In the coming years, QBBK wishes to go further and aim for finished products with high economic value, as well as expand cooperation with all domestic and foreign partners in this field.
In addition to traditional product lines, such as DH350, DH500 and DH500M, from the beginning of 2023, K85 and K95 have been mass produced with ultra-fine particles, average 7.0 µm and 5.7 µm.
- Kaolin K95: humidity 12%, product packaging: big bag or 50kg PP bag; 25kg.
- Kaolin K85: humidity 12%, product packaging: big bag or 50kg PP bag; 25kg.
- Kaolin DH350: humidity 27%± 2%, product packaging: lumps, pieces; Bulk goods, packaged if required by the customer. It is an indispensable raw material in the ceramic industry, unburnt bricks, granite bricks,...
With great potential and good quality, in the coming time, we at QBBK will focus on producing high-end product lines and bringing these high-end product lines to the European market.
In the future, our goal is METAKAOLIN. QBBK's Metakaolin as the ideal supplementary material.
The rogue chemical composition of metakaolin enables the material to behave itself as the ideal supplementary cementitious material among other minerals and by-products that are in practice at present.
Metakaolin is produced by thermally activating high-purity kaolin clay within a specific temperature. The heating process pills out water from the kaolin (Al2O3.2SiO2.2H2O) and alters the material structure resulting in an amorphous alumino silicate (Al2O3.2SiO2)-metakaolin. Metakaolin, when combined with cement, reacts rapidly with CaOH that is released from the hydration of cement to develop various hydrates namely C-S-H, C2ASH8-stratlingate and C3AH6-hydrogarnet.
Amidst many mineral admixtures accessible, metakaolin is a mineral admixture whose prospects have been fully tested for the development of high strength concrete. Due to high surface area and amorphous structure, MK shows high pozzolanic reactivity. Incorporation of MK in concrete has improved the performance of concrete under various conditions. Also, the ultrafine MK enhanced substantially the pore structure of the concretes and reduced the content of the harmful large pores, hence making concrete more impervious, especially at the replacement level of 20%.
