Rainy season rubber and plastic insulation materials construction precautions
Recently, affected by the convergence of cold and warm airflow, the strong wind and rain weather in the country has brought severe tests to the construction. So, what matters should be paid attention to during the construction of rubber and plastic insulation materials?
First, rubber and plastic insulation material storage
Inorganic active thermal insulation mortar storage must pay attention to waterproof and moisture.
1. Indoor storage: When the construction conditions permit, and the current YT insulation materials are not many, the insulation materials can be stored indoors. In order to prevent the impact of increased air humidity on the material caused by rain and rain, the indoor window should be blocked to prevent rain. The materials are piled up 30 cm from the ground and covered with tarpaulin to prevent water from building up on the rain due to rain and weather, causing leakage of the modified YT insulation material.
2. Outdoor storage: Select the place where the terrain is high, the surrounding drainage is smooth, it is not easy to accumulate water, and it is more than 30 cm above the ground. Before stacking, lay a layer of tarpaulin on the material table to prevent moisture. After stacking, cover the top with a full tarpaulin, tie it with a rope, and press the tarpaulin around with heavy objects. Pay attention to the weather changes. When it is sunny, open the poncho to dry the air, and evaporate the tarpaulin water to prevent the water vapor from producing water droplets and drip on the YT inorganic active insulation material, causing hardening.
Dark Tea Powder
Black tea (dark tea) is named after the black appearance of the finished tea. It is one of the six major tea groups and is a post-fermented tea. The main production areas are Guangxi, Sichuan, Yunnan, Hubei, Hunan, Shaanxi and Anhui. The traditional black tea is made from high maturity black wool tea, which is the main raw material for pressing tightly pressed tea.
The process of making black tea generally includes four steps: killing, kneading, stacking and drying. Black tea is mainly classified as Hunan black tea (Fu tea, Qianliang tea, black brick tea, Tri-tip, etc.), Hubei green brick tea, Sichuan Tibetan tea (border tea), Anhui Gu Yi black tea (An tea), Yunnan black tea (Pu'er tea), Guangxi Liubao tea and Shaanxi black tea (Fu tea) according to geographical distribution.
The yellow powder in black tea is commonly known as golden flower, a beneficial microorganism, the so-called golden flower, is in the processing of raw materials through the flowering of this special procedure, specifically in the black tea bricks to cultivate a kind of coronary aspergillus substance called coronary scattered cystic bacteria, commonly known as the golden flower, observed under the microscope, each individual golden flower is umbrella-shaped clusters, the whole body is golden and eye-catching, ringed into a group, evenly distributed.
