The difference between hot-dip galvanized sheet and other steel sheets

2019-02-28 10:27:21 | steel coil
What is the difference between hot-dip galvanized sheet and other steel sheets? Let the low cost hot dip galvanized steel coil factory tell you the specific reason.

The hot-dip galvanized steel sheet has a thick zinc layer and a good anti-rust effect, which greatly lengthens the service life of the steel sheet. We all know that every thing will be damaged when it is used for a long time. In order to lengthen the service life of the product, it is very important to prevent the corrosion of the product. The steel plate is not a special case. Spraying, painting, aluminizing, and galvanizing aluminum are still available in the anti-corrosion process of steel gratings, but they are not mainstream.

The advantages of hot-dip galvanized steel gratings are exceptionally obvious. The use of hot-dip galvanized steel gratings can reduce wind resistance. Therefore, the use of hot-dip galvanized steel sheets has a good time for ventilation, and even in the case of strong winds, the wind resistance can be made small, so that Reduce the damage of the wind.

The design of the hot-dip galvanized steel sheet is also quite convenient. There is no structure of the small beam, the structure is extraordinarily simple, and the design is simplified. The ventilation effect of the hot-dip galvanized sheet is obvious, and its lighting effect. It is also quite good, the heat dissipation and explosion-proof function of the hot-dip galvanized grid are exceptionally excellent, so the hot-dip galvanized steel plate has a good reputation.

The Uniqueness Of Geotextile Mechanism

The high quality PET non woven geotextile should be protected from damage before installation. The geotextile rolls should be stacked in a place where there is no water accumulation, the height of the pile should not exceed four rolls, and the identification piece of the roll can be seen. Resistance strain gauge measurement is commonly used in strain measurement of geosynthetic materials. In this method, the strain gauge is attached to the surface of the object to be tested, and the strain change process of the measured point is recorded by the principle that the resistance of the strain gauge changes with the mechanical deformation of the object to be measured.
 
The wholesale long fibre filament needle punched geotextile has the advantages of lightweight, low cost, corrosion resistance, anti-filtering, drainage, isolation, reinforcement, etc. The following is a high quality PET non woven geotextile production method. The short-fiber needle-punched short-fiber combing machine or the waste cotton opening machine is used to make a cotton net.

Then, the air mesh is arranged in a cross-stack, or directly formed by an air-laid machine to achieve the isotropic property of the cloth, and then a set of needles or a plurality of sets of needles are used to perform the needle-punched fiber web. The fibers are entangled with each other and pressed together to form a nonwoven fabric. This method is suitable for the production of thick geotextiles. It is characterized by high density, fluffy structure, thick, good water absorption and water permeability, and high resistance to deformation. It is especially suitable for filtration and drainage projects.

The spunbond process melts the particles or powder of the polymer and then enters the extruder and is spun into a continuous filament bundle through one or a series of spinnerets. The filaments are then irregularly arranged by rotating the spinneret or by controlling the air flow, changing the speed of the conveyor belt, passing current, etc., and laying them on a conveyor belt to form a fiber web. The bonding of the web is carried out by hot pressing or bonding with a binder, or by needle punching, to form a continuous uniform high quality PET non woven geotextile. It can be used in various projects such as reinforcement, separation, filtration, and drainage.


Use of the galvanized coil

2019-02-26 10:54:34 | steel coil

When you are in the streets of some industrial parks, I believe that you will always encounter some cars that look very heavy. They are pulling rolls of steel which are steaming or big or small. Many of us don't know what these things are and what they are used for. Yes, it is China high quality prepainted color galvanized coil.

China high quality prepainted color galvanized coil is a new kind of material. It is coated with zinc on the surface of the steel plate. It plays an anticorrosive role by utilizing the physical properties of zinc. As a new material, high quality prepainted galvanized steel coil is widely used in construction industry and light industry. There is also a great market demand. According to authoritative statistics, the application of galvanized coil sheet in these two industries can reach about 30% of the total.

In addition, high quality prepainted galvanized steel coil is a kind of steel which has been widely used in life and has been treated with anticorrosion, ranging from small tables, chairs, and benches to large pavilions and pavilions. Seriously looking for it, we can find the figure of a galvanized coil. It is only because of different uses, different processed forms, and some places which we do not notice, such as ventilation pipes in buildings, and others on the surface. But after beautification, we can't see it, such as the back cover of the refrigerator. China high quality prepainted color galvanized coils are most widely used in construction and light industry, accounting for about two-fifths of the total application.

Geomembrane WeldingGeomembrane anti-seepage geotechnical

Geomembrane Welding

Geomembrane anti-seepage geotechnical materials, presumably many customers should be familiar with it. One of the most concerned issues is the issue of high quality textured hdpe geomembrane welding. Today, we will introduce you to the welding of HDPE geomembrane in special parts. Let's take a look at it:

1. Connection of dam pipe and geomembrane: Firstly, the HDPE geomembrane is cut into a trumpet-shaped pipe sleeve according to the diameter of the leachate through the dam pipe, divided into 6-8 small pieces, and then the pipe sets are ordered from large to small. The sleeve is inserted into the dam tube, and the position of the sleeve is adjusted appropriately and temporarily fixed by a hot air welding torch. The sleeve cannot be suspended, and finally the sleeve of the sleeve is welded to the HDPE geomembrane and the leachate through the dam tube. The geomembrane is reinforced with stainless steel hoops.

2. At the intersection of the slope of the reservoir area and the bottom of the reservoir, there are many blind trenches in the design. First, the HDPE geomembrane is laid along the dam surface at a distance of 1.5 meters away from the blind ditch and then connected to the base film. The welding of the adjacent two pieces is: first welded and then pressed into the blind ditch.

3. The intersection of the slope, that is, the bend of the dam slope: laying and welding are special cases. Special cutting according to the actual conditions can make the HDPE geomembrane close to the dam slope base, otherwise it will cause ��hanging�� or ��drumming�� phenomenon. In this area, the operator should carefully measure the HDPE geomembrane into an inverted trapezoid with a narrow upper and lower width.

Geomembrane LayingFirst of all, the contact surface of th

Geomembrane Laying

First of all, the contact surface of the hot sale hdpe geomembrane pond liner and the supporting material should be flat, so as to prevent the film from being punctured and lose its anti-seepage effect. In the uneven place, a fine grain cushion can be laid in advance to protect the film from damage.

Secondly, the geomembrane itself is tightly connected, and the geomembrane connection method includes a bonding method, a welding method, and a vulcanization method.

Third, the geomembrane and the surrounding boundary must be tightly combined. If the foundation is a shallow sand gravel permeable layer, the geomembrane manufacturer should dig the gravel to the bedrock, then pour the concrete base to fix the geomembrane in the concrete. Some foundations are impervious clay layers. The anchoring tanks can be excavated to a depth of 2 meters and a width of about 4 meters. The geomembrane is placed in the tank, and then the clay is densely backfilled. The local base is a deep sand gravel permeable layer. The geomembrane is covered by means of anti-seepage, and its length is determined according to calculation.

When laying, the geomembrane should not be pulled too tightly, and the two parts buried in the soil part are corrugated, especially when anchored with rigid materials, there should be a certain amount of expansion and contraction.
