Galvanized Steel Coil
Galvanization or galvanizing is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing(Galvanizing of hot sale galvanized steel coil is a hot dip galvanizing method), in which the parts are submerged in a bath of molten zinc.
Protective action
Galvanizing protects the underlying steel? coil in the following main ways:
�� The zinc coating, when intact, prevents corrosive substances from reaching the underlying steel or iron.
�� The zinc protects iron by corroding first. For better results, application of chromates over zinc is also seen as an industrial trend.
�� In the event the underlying metal becomes exposed, protection can continue as long as there is zinc close enough to be electrically coupled. After all of the zinc in the immediate area is consumed, localized corrosion of the base metal can occur.

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.

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.

Steel Sheet characteristics

No matter what product we use, we must first understand its characteristics and performance in order to use it scientifically and reasonably. The following is mainly about the characteristics and scope of the high quality Galvanized Corrugated Steel Sheet:

The roof slabs are mainly used for modern industrial buildings, chemical fertilizer plants, sewage treatment plants, electroplating plants, power plants, aquaculture plants, markets, warehouses and other large industrial building roofs and wall new construction and plant renovation projects.

1. Excellent weathering and anti-corrosion--It has been verified by practice that the products have good weather resistance under various climatic conditions and exhibit good corrosion resistance in chemical corrosion of acid, alkali and salt.
2. Outstanding waterproof performance - the use of waterproof layer in the 15-90 degree slope roof building
