We decided to have a picnic in the park. We spread out a blanket and opened a basket of food. We ate sandwiches, French fries and fruit. We even ate some cookies for dessert.
Carpets, seats, plastic parts of dashboards, roof blankets and glue used in decoration are the main sources of air pollution in automobile interior. Due to the narrow interior space and good tightness, the harmful gas in the car is more harmful to the human body than the indoor harmful gas. The harmful gases contained in automobile interior mainly include benzene, toluene, xylene, ethylbenzene, styrene, formaldehyde, acetaldehyde and so on.
The effect of thermal insulation is good, the thermal insulation layer adopts heat-resistant fiber thermal insulation blanket, and the surface hairiness is rich and similar to down. Thermostable ℃. Easy to disassemble, easy to install, easy to clean pipeline equipment, easy to repair and maintain. It can be used repeatedly for a long service life. High strength, toughness and easy to bend bandage. Can be tailored according to the need for heat preservation parts, processing non-standard products. The product has strong adaptability and is suitable for piping equipment with different temperature ranges and different shapes. Environmentally friendly, pollution-free, free of asbestos and any other harmful substances, harmless to people and completely. The appearance of the product is beautiful and neat and the surface can be scrubbed. Work hot, prevent personnel. Indoor temperature, convenient for air conditioning cooling, comfort.
To ensure the good reliability and stability of aluminosilicate needle blanket at high and low temperatures, this product is widely used in the field of fire-resistant and thermal insulation and other industries. Aluminosilicate refractory fiber products with different refractory temperatures can be produced according to different raw materials and processing processes: ordinary refractory fiber cotton (working temperature: < 1000 ℃) Standard refractory fiber cotton (working temperature: 1050 Songjiang District, Shanghai Province, aluminum silicate needle blanket spot manufacturers supply aluminum silicate refractory fiber blanket price ℃).
1. Working temperature: not all aerogel insulation blankets can work at temperatures as high as 1300 ℃. Confirm the recommended working temperature of the products sold with the manufacturer before purchase to avoid safety risks;
As concrete needs a certain temperature guarantee during pouring, attention should be paid to the heat preservation of concrete to prevent the temperature caused by heat loss from being too low to meet the requirements. In the concrete pouring at the same time to ensure the temperature, if there is too low temperature, concrete pouring is bound to have quality problems. When the concrete has not yet solidified, it needs to be insulated. In modern times, the usual practice is to ensure the temperature of the electric heating equipment. Usually: build a slow platform to keep the heat at a height of 30cm, gradually withdraw the electric blanket, and inject cooling water into the Weir on the top surface.
Shandong thermal insulation pipe products are complete in about 5 minutes after the end of pouring and foaming (according to the ambient temperature), remove the sealing flange and cover the sleeve pipe, seal the filling hole with a plug, place the pipe horizontally and number it; 6. After passing the inspection, hoist the insulation pipe to the finished product area. Installation of directly buried prefabricated thermal insulation pipe: 1. Wrap the first layer of thermal insulation material aluminum silicate fiber blanket on the working steel pipe 2. Add calcium silicate (tile shell) 3 to the aluminum silicate fiber blanket. Polyurethane foam is irrigated in the mold. After removing the mold to make FRP insulation pipe polyurethane foam on the glass steel pipe winding machine has good mechanical properties and thermal insulation properties, usually can withstand temperature 120 ℃, through modification or combined with other thermal insulation materials can withstand temperature 180 ℃.
