The invention relates to a manufacturing method of a concrete pavement brick with a surface course. The manufacturing method of the concrete pavement brick with the surface course is characterized in that a surface course brick body and a base course brick body are included, and concretely comprises the following steps that 1, the base course brick body is made from concrete and gravel, wherein the component ratio between the concrete and the gravel is 1-1.5:1 and the concrete and the gravel are made through vibration compression; 2, the base course brick body is warmed and preheated and the temperature is maintained for 2-5 minutes; 3, primer is evenly sprayed on the surface of the base course brick body; 4, the surface course brick body is manufactured above the primer, wherein the surface course brick body is made of cement, coarse sand, silica fume and emulsion; meanwhile, a curing agent is added in the manufacturing process of the surface course brick body; 5, the surface course brick body is warmed and the temperature is maintained for 3-5 minutes. By applying the manufacturing method of the concrete pavement brick with the surface course, the color and lustre of the pavement brick is improved, the pavement brick can have long service life in the complicated external environment and is resistant to water erosion and wind decay, thus the high temperature resistance and anti-friction properties of the pavement brick are improved, the pavement brick can maintain the original color for a long time, and the pavement brick is prevented from being frosted.

The invention relates to the technical field of heating devices, and discloses an underwater working heating garment for heating based on the principle that a compound releases heat when encounteringwater. The garment comprises a waterproof outer layer, and a thermal insulation layer is fixedly connected to the inner part of the waterproof outer layer. According to the underwater work heating garment for heating based on the principle that compounds release heat when encountering water, when a user works underwater, a small-sized water pump can regularly pump reaction water from the water byutilizing the water inlet to enter the heat supply chamber. The reaction water slowly flows into the reaction chamber through the water outlet under the adjustment of the small water pump. The reaction water and chemical reactants are subjected to exothermic reaction in the reaction chamber to generate a large amount of heat. The released heat can promote the reaction water to be converted into hot gas carrying heat. Hot air can flow out of the reaction chamber from the vent holes in the top plate, when the hot air in the heat supply chamber is gathered to a certain degree, the hot air can flow to the airflow layer along the steam pipe, the hot air can flow to any position of the heating garment in the airflow layer to supply heat to the heating garment, and the effect of supplying heat towearers underwater is achieved.

The invention discloses a surface-modified pretreatment fire-resistant anchoring brick and a preparation process thereof. Nowadays, generally in order to prolong the service life of a furnace lining,it is usually needed to ensure that all the properties of the anchoring brick should be consistent with the texture of a lining material, but during actual operation, the anchoring brick and the lining material are generally prepared from two different materials based on cost and the needs of actual production, and thus in the high-temperature or furnace cooling process, the situation that due toinconsistent expansion and shrinkage between the anchoring brick and the lining material, local stress asymmetry is caused, and therefore the anchoring brick cracks is caused. Aiming at the problem, the surface-modified pretreatment fire-resistant anchoring brick and the preparation method thereof are designed, and the surface of the anchoring brick is coated with a modified coating. The surface-modified pretreatment fire-resistant anchoring brick is reasonable in process design, the stress between an anchoring brick body and the lining material can be effectively buffered, and the anchoring brick is prevented from cracking; and meanwhile the structural strength of the anchoring brick body is improved, and high practicality is improved.
