cationic polymer used in water treatment

Another significant additive is corrosion inhibitors. Corrosion is a common problem in chilled water systems due to the presence of metals like copper and steel. Over time, these metals can corrode, leading to leaks and lower system efficiency. Chemicals such as sodium nitrite, sodium molybdate, and organic inhibitors like azoles are often used to provide a protective layer on metal surfaces, reducing the rate of oxidation and extending the lifespan of the equipment.

Spring steel wire should have high tensile strength, elastic limit, endurance and fatigue strength, and resistance to impact and oscillation. The strength and endurance objectives, especially to prevent the occurrence of modification cracks, are the key to the consumption of spring wire. The inner quality and outer quality of the wire rod directly affect the function of the wire.

Galvanized hexagonal net is a kind of galvanized metal wire mesh, mesh shape is hexagonal.
- It is generally believed that the positive and negative twisting wire wire is not as durable as the thickness, common sense thinks so, but the positive and negative twisting wire wire is used in hot galvanized steel wire, which is more than 3 times the tensile strength of the iron wire, and the zinc amount is not lower than the hot plated wire

Annealed wire is a soft iron wire made of low carbon steel cold drawing, heating, constant temperature, heat preservation and other processes. The composition of iron wire varies according to its use. It contains iron, cobalt, nickel, copper, carbon, zinc, and other elements. The hot metal billet rolled into 6.5mm thick steel bar is the wire rod, and then put it into the wire drawing device into a different diameter of the line, and gradually reduce the aperture of the wire tray, cooling, annealing, plating and other processing technology made of various specifications of iron wire.

Broken wire is the iron bright wire, fire wire, galvanized wire, plastic coated wire, paint wire and other metal wire, wire factory according to customer requirements for straightening after sizing cut, has the characteristics of easy transportation, easy to use, widely used in the construction industry, handicrafts, daily civilian and other fields. No limit on length, packing as required. Annealing wire also known as black oiled wire, black annealing wire, fire wire, black iron wire. Compared with cold drawing, black annealed wire is more economical as raw material for nails.
- It is recommended to have a brush, comb or rake ready before bathing your dog; Shampoo, conditioner, shower gloves, tether, bath mat, floor drain lid, spray, towel and shower shower.

Hexagonal twist flower network is divided into heavy hexagonal network and small hexagonal network two categories. Both are made of steel wire braided with various materials, the difference is that the former uses thicker steel wire, and the latter uses finer steel wire braided.

River isolation network because of different regions are not close to the same, some places called river guardrail network, reservoir isolation network and called river bridge guardrail and so on, but they refer to the same kind of product, we all know that the river isolation network fence itself is a kind of obstacle, to prevent people and cars falling into the river, if installed river isolation network will not appear such a problem, Its setting is conditional, generally in the river fence set guardrail and more people and vehicles installed guardrail maintenance, the relative risk of discrimination. As long as the correct planning, guardrail to play its own function and advantages. Today, I will introduce to you the style of the river isolation network.

Post time: 10-03-23 - Compared with hot-dip galvanized barbed rope, it is much better in the circle of mountains and forest protection. Because it can choose several colors on its appearance, different sites have different colors, which is both beautiful and practical, so as to facilitate the growth of natural plants and gradually recover the original ecological environment.

Hexagonal mesh is also known as twisting mesh, thermal insulation net, soft edge net. Material: low carbon steel wire, stainless steel wire, PVC wire, copper wire knitting: straight twist, reverse twist, two-way twist, first after plating, first plating after knitting, and hot dip galvanized, zinc aluminum alloy, galvanizing, PVC coated, etc. Features: Solid structure, flat surface, with good corrosion resistance, oxidation resistance and other characteristics. Uses: Used for raising chickens, ducks, geese, rabbits and zoo fences, mechanical equipment protection, highway guardrail, etc.
-
The use of steel mesh saves a lot of on-site binding and construction site, can end civilized construction, advance the quality of steel structure engineering. Because the steel mesh is prefabricated in the factory, there is no need for site reprocessing, and there is no need for steel chips, because the construction cycle is shortened, and the cost of lifting machinery is reduced.

Although galvanized iron wire has the protection of galvanized layer, it does not say that it will not rust at all, but delays the time of rust. In general, cold galvanized iron wire can be kept for 1-2 years without rust, hot galvanized iron wire can be used for 8-10 years without rust. If properly maintained, the use time will be longer. So how to prevent galvanized iron wire rust?

Post time: 28-10-22 - The COMBINATION OF disSIMILAR METALS, such as steel and copper, tin, lead and other non-ferrous metals, during hot dip operation, the dissolution of this non-metal will cause the change of zinc film structure. Also like the combination of old and new steel, in pickling operation, the new material is easy to pickling over. In addition, such as part of the processed components, excessive pickling at the processing place is also.

Using activated carbon mat to remove surface active substances, or through filtration to make the foam is not too stable, this is an effective measure; Other measures should also be taken to reduce the amount of surfactant introduced to Z.
- Since nose touching is an important part of a dog’s social behavior, humans can use this to train them. Experts say that if owners touch their dogs’ noses regularly when they are young, they will have softer personalities and be less likely to hurt when they grow up.
- The common barbed rope produced by the manufacturer is the 14*14 type of barbed rope product. Since the warp wire used is the same as the wire diameter of the barbed rope, it is easier to calculate the length and weight. Usually each kilogram of barbed rope can reach about 10 meters of service length. The length of each kilogram of raw material is about 35 meters. Since 35 meters of raw material wire diameter can produce 10 lengths of barbed rope cost.

Galvanized wire to galvanized uniform, a body is now its cross section, the second is the longitudinal uniformity. In the actual operation process, such as the jitter of steel wire, the surface of the pot scum and other reasons will cause galvanized wire surface galvanized layer accumulation, should try to solve the problem.
