Henan Huaming Water Treatment Material Co., Ltd. specializes in the production of water purification agents for wastewater treatment and wastewater treatment of coal-fired power plants.

Since polyacrylamide is the most widely used synthetic flocculant, this precipitation method is an important method for solid-liquid separation of difficult-to-deposit particles in the water treatment industry due to its simplicity and high separation efficiency. It is used in wastewater treatment applications. Acrylamide is a good flocculant, its nature directly affects the flocculation effect, and then determines the follow-up process and the quality of the water, so it must continue to develop to meet the increasingly complex requirements of sewage components.

Second, product characteristics

1. Rapid formation of large flocs, large and compact pods, low sludge volume and fast flocculation;

2. Dissolve quickly and thoroughly without insoluble matter (fish eyes); powder state products dissolve for 5-10 minutes;

3. Economical and practical - small amount, good effect, high dehydration rate; low operating cost, low dose can produce effective effect and high dehydration performance, very economic;

4. Excellent filtration and dewatering improve the dewatering effect of sludge;

5. Water treatment suitable for industrial water supply, municipal wastewater, chemical wastewater, mines and other industrial fields can accelerate the settling velocity of sediments and increase the dehydration efficiency because synthetic floes are easily filtered.

6. Should be on-site commissioning or beaker experiments according to different conditions, to obtain the best conditions for use and determine the best product and dosage;

Three: Appendices

In order to make the rapid precipitation of waste water in the concentration tank, to ensure better treatment of qualified waste water, and to make the production efficient and economical, it is necessary to select an appropriate flocculant: polyacrylamide to strengthen the treatment of waste water. Through the production practice in recent years, it has been proved that polyacrylamide has good effect on wastewater treatment, which can accelerate the sedimentation of wastewater and contribute to pressure filtration production.

Welding Glasses

Welding Safety Glasses

Welding Safety Glasses help protect welders against Photokeratitis, also known as "welder's flash." Welding Safety Glasses are designed with Shade 3 or Shade 5 Lenses and are primarily used for torch soldering, brazing and cutting. Welding Safety Glasses are not intended for arc welding, which requires a darker lens found in Welding Helmets (OSHA's 29 CFR 1910.252 lists the minimum lens shade requirements for a variety of welding operations).

Visible Light Transmission for each lens shade: Shade 2 = 20-28%, Shade 3 = 10-14%, Shade 5 = 2-4%

Welding goggles provide a degree of eye protection while some forms of welding and cutting are being done. They are intended to protect the eyes not only from the heat and optical radiation produced by the welding, such as the intense ultraviolet light produced by an electric arc, but also from sparks or debris.[1] A full facemask may be required for arc welding.

Welding and cutting processes, including arc welding and cutting, as well as brazing produce intense ultraviolet (UV), infrared (IR) and visible light wavelengths. The UV and IR wavelengths cannot be seen and can produce eye injury without the victim realizing it immediately. Extremely dark filters of the proper sort are needed for the welder to be able to look at the intensely glowing metal being welded. An approved face shield or welding helmet can also have filters for optical radiation protection, and offer additional protection against debris and sparks.[2] UV blocking protective spectacles with side shields or welding goggles are considered primary protection, with the face shield or welding helmet considered secondary protection.[3] This way, the eyes are still protected even when the face shield or helmet is lifted up.[4]

The optical filter in welding goggles, face mask or helmet must be a type which is suitable for the sort of work being done.[5] A filter suitable for gas welding, for instance, should not be used for arc welding. Face masks which are self dimming are available for arc welding, MIG, TIG, and plasma cutting, and allow better vision before the arc is struck and after it is extinguished.[6] Failure to use such protection when arc welding or even being near where arc welding is going on can result in a painful condition called [arc eye" or photokeratitis, which is akin to a severe sunburn of the cornea and conjunctiva of the eye.
