Business in the Pile qualification qualification, the qualification grade steel, a qualified indoor environment, building energy efficiency testing, subject testing, materials testing, glass curtain wall testing, roads and bridges detection, detection of a number of civil air defense projects testing qualification and testing laboratories. Daily Chemicals to people's lives a great deal of influence. Chemical Waste wide range of Xiangcheng pile testing, and people's basic needs are closely related. Its use can be divided into the following 13 categories: detergents, cleaning agents, dyes, polishes, cosmetics, food additives, adhesives, coatings, fur and leather protective agent, household medicines, insecticides, household aerosols and others. Not only are many kinds of daily chemicals, chemical substances contained also different. The wide variety of chemical suppliers water pile testing, or as a main ingredient, add ingredients or impurities. Thus, in the course of possible pollution of the environment, especially indoor air pollution, which affects the health of users and occupants. Aniline is highly toxic in small amounts for the production of paints, varnishes, dyes, antioxidants, herbicides, insecticides, fungicides, insecticides and other home and household chemicals, which can cause damage to the human body. Henan malpractice Construction Engineering Testing Co., Ltd. is a professional testing company, is one of the qualification place in Henan Province since the first detection through examination of business. Business in the Pile qualification qualification, the qualification grade steel, a qualified indoor environment, building energy efficiency testing, subject testing, materials testing, glass curtain wall testing, roads and bridges detection, detection of a number of civil air defense projects testing qualification and testing laboratories. Syringe samples. Common 100mL syringe connected to a three-way piston to collect organic vapor samples. First with on-site sampling air extractor 3 to 5 times pile testing and sampling, sealing air intakes, air intakes syringe down, vertically, make slightly larger than the atmospheric pressure inside the syringe. In addition Xihua pile testing, pay attention to the sample storage time not too long, generally the day the analysis is complete. ② plastic samples. Should be chosen with the sample gas pollution component is neither chemical reaction nor adsorption, impermeable plastic bags. Commonly used Teflon bags, polyethylene bags and polyester bags. In order to reduce the adsorption of components, the inner wall lining in silver, aluminum and other metal membrane pocket. Sampling, the first scored with a double ball-site gas washing 2 to 3 times, and then charge the sample gas, pinch inlet, back to the laboratory analysis. ③ tracheal samples taken. Mining endotracheal tube is a glass container having two ends cock, its volume is 100 ~ 500mL. Sampling, the open ends of the cock, the double-ball or suction pump connected to the end of the tube quickly drawn into the more than 6 to 10 times the volume of large mining gas desire to make mining trachea replacement of the original gas was completely shut the ends cocks, gas volume is collected volume of the trachea. ④ vacuum bottle sampling. Vacuum bottle is fixed by a pressure-resistant container made of glass, volume 500 ~ 1000mL (see FIG 42). Before sampling, first vacuum means mining evacuated to a residual pressure within the cylinder of about 133kPa can, such as bottle pre-loaded absorbing liquid can be pumped to the bubble appears, close the piston. Sampling in the field to open the cork, quarried gas into the bottle, close the cocks, sent to the laboratory analysis. If the vacuum bottle vacuum up to less than 133kPa, in terms of sample size should be based on the residual pressure.
