Dacheng teaches you how to buy high quality rock wool board?
High quality rock wool insulation boards should have the following characteristics:
1, should have a lower thermal conductivity. The thermal conductivity is an important indicator to measure the performance of rock wool board. The smaller the thermal conductivity, the less energy is transmitted through the material, and the better the thermal insulation performance of the thermal rock wool board. (Note: This article also applies to vertical silk wool board, waterproof rock wool board, etc.)
2, should have a higher sound absorption coefficient, the sound absorption effect of the thermal insulation rock wool board mainly depends on the density of the rock wool board in the unit area, the greater the density, the better the sound absorption effect.
3, a good rock wool board should have a low hygroscopicity, most of the insulation material will have a significantly lower heat preservation effect after water absorption, because water has a higher thermal conductivity. Therefore, customers are advised to choose waterproof rock wool board.
4. A good insulated rock wool board must be able to have a high strength to support its own weight.
Teapot is a kind of mouthed utensil for making and pouring tea. It is a kind of tea set, mainly used to make tea. The teapot is composed of a lid, a body, a bottom and a ring foot. The lid has holes, buttons, seats, covers and other details. The pot body has mouth, extension (lip wall), mouth, flow, abdomen, shoulder, handle (handle, wrench) and other parts. Because of the subtle differences in the handle, lid, bottom and shape of the teapot, there are 200 basic shapes of the teapot. When making tea, the size of the teapot depends on the number of tea drinkers. Teapots have a lot of texture, most of which are made of purple clay or porcelain.
