Abstract

The invention provides a manufacturing method of an inorganic reinforcing agent for gypsum products, and belongs to the field of novel building materials. Calcium carbonate, calcium sulfate, potassium sulfate and other common materials are selected and accurately weighed, the materials are ground and sieved by a 250-mesh sieve without processing, the materials are sintered in an intermittent shuttle-type kiln or a continuous rotary kiln, after sufficient cooling, the sintered materials are ground and sieved by a 325-mesh sieve, the ground materials are cooled and homogenized, and the product is checked and packaged if qualified. The strength of a common gypsum product with 1%-5% of the inorganic reinforcing agent doped is increased by 1-2MPa or more, and thus the inorganic reinforcing agent is greatly helpful for upgrading gypsum product industries, and can be widely applied to house decoration or other building products.

Description

technical field [0001] The invention relates to a method for manufacturing an inorganic reinforcing agent used in gypsum products, and belongs to the field of new building materials. Background technique [0002] Gypsum building materials are attracting more and more people's attention and favor because of their excellent characteristics such as light weight, fire resistance, "breathing" and low carbon. However, gypsum is used in building products because of its low strength and non-moisture resistance, which limits its use. Our country is very rich in gypsum resources. The proven natural gypsum amounts to hundreds of billions of tons, and the chemical gypsum only phosphogypsum and desulfurized gypsum amount to more than 100 million tons. How to make full use of the excellent characteristics of gypsum and gradually solve its defects in the process of use , It is to protect natural resources and realize sustainable development and utilization; to eradicate chemical pollution...
