Buying stock epoxy curing agent-Shanghai Fengxian acquires Phthalocyanine green bidding price
Last week, a friend called me and asked me that the air contains moisture and requires dehumidification. He said that steam heating should be used to dry the air. I don't understand this a bit. Speaking of air dehumidification, I think of air condensation. In winter, condensation on indoor window glass is like. The indoor temperature is higher and the outdoor temperature is colder. When the higher temperature air hits the very cold glass surface, it will There are small water droplets, which is the phenomenon of condensation. Air dehumidification has two methods: cooling and dehumidification and dehumidifier dehumidification. Cooling and dehumidification is to use a radiator to pass a refrigerant to remove moisture when the humid and hot air passes through. The dehumidification price of dehumidifier is relatively high, and the dehumidification of large air volume will be very expensive.

DON may play a role in more than one way at the same time. Vomiting detection methods There are many detection methods for vomiting. The more classic detection methods that have formed national or industry standards for implementation mainly include: liquid chromatography, mass spectrometry, thin layer analysis, enzyme-linked immunoassay, and colloidal gold test strip method. The vomiting and vomiting detector for wheat can not be underestimated. The vomiting detector uses the absorption of light of a specific wavelength with a colloidal gold test card to obtain the light absorption peak signals on the T line and the C line of the chromatography test paper, and calculate the two peak areas based on this Then make a standard curve based on the ratio of the standard concentration and the peak area. In the actual test process, the ratio of the two peak areas can be obtained by the vomiting detector, and the items to be tested can be obtained according to the drawn standard curve The quantitative results. (This machine can be used for primary filtration, decarburization, deep filtration, semi-precision filtration, fine filtration) The filtration device of this machine is composed of multiple layers of overlapping filter screens and filter frames. The screen holes are punched by a computer, and the hole density is small and uniform This can ensure that the pressure of the filter material on each layer of the filter screen is even, so that the filtration accuracy is excellent. The original liquid enters the cylinder through pressure, enters from the holes around the filter frame, and then passes through the filter medium on the screen. A small hole comes out, and the qualified liquid is discharged. The filter material of this machine can be selected (polypropylene filter membrane, enhanced filter membrane, filter paper, filter cloth, special decarburization filter membrane), etc. Suitable filter materials can be selected according to user requirements. The characteristics of this machine: large flow, fast speed, more viable carbon, small space occupation, large filtering area, high efficiency, high filtering precision, easy operation, etc.
Our company recycles thousands of chemical raw materials. There are many kinds of recycled materials, various styles, unlimited quantity and quality, and they can be recycled after they are scrapped. Our company has complete qualifications and is safe to recycle and reuse. The sales staff are all over the country and pick up the goods personally. You solve the inventory problem. We are looking forward to cooperating with you on the 24-hour wealth hotline!
