Galvanized belt square tube characteristics:

Zinc plating has greater protection and strong corrosion resistance. The entire structure consists of zinc, forming a dense quaternary crystal that forms a barrier on the steel sheet to effectively prevent the penetration of corrosion factors. Corrosion resistance comes from the barrier function of zinc. When zinc is sacrificed in the dressing, scratching and scraping of the coating, the zinc forms an insoluble oxide layer which acts as a barrier.

The use of Galvanized square tube:

Since the galvanized square tube is galvanized on the square tube, the application range of the galvanized square tube is greatly expanded compared with the square tube. Mainly used for curtain wall, construction, machinery manufacturing, steel structure engineering, steel structure support, steel structure engineering, billboards, agricultural machinery, furniture tubes, etc.

Calculate the theoretical weight per square meter of galvanized square tube:

4 * (side length – thickness) * 0.00785 × 1.06 * Thickness, where the side length and wall thickness are in millimeters, this value is directly substituted into the above formula, that is, the weight per square meter, in

For a square tube of 30 x 30 x 2.5 mm, the weight per meter can be calculated as follows: 4 x 2.5 x (30-2.5) x 7.85 = 275 x 7.85 = 2,158.75 grams, or about 2.16 kg.

When the wall thickness and side length are in millimeters, 4 × wall thickness x (side length – wall thickness) is calculated as the volume of the square tube per meter length, in cubic centimeters, multiplied by the specific gravity of 7.85 per cubic meter of iron. The gram is the weight of kilograms per square meter.

Process characteristics of galvanized steel pipe

Galvanized pipes, also known as galvanized steel pipes, are divided into hot-dip galvanizing and electro-galvanizing. The hot-dip galvanizing galvanized layer is thick, with uniform plating, strong adhesion and long service life. The cost of electroplating is low, the surface is not very smooth, and its corrosion resistance galvanized steel pipe supplier is much worse than that of hot-dip galvanized pipes.

Process characteristics of galvanized steel pipe:

1.Conversion of sulphate galvanizing

The sulphate electroplated zinc-iron alloy retains only the main salt of zinc sulfate galvanized zinc sulfate, and the remaining components such as aluminum sulfate and alum (potassium aluminum sulfate) can be added to the bath to form insoluble hydroxide precipitates. Removal; for organic additives, add powdered activated carbon to remove. Tests show that aluminum sulfate and aluminum aluminum sulfate are difficult to remove completely at one time, which has an effect on the brightness of the coating, but it is not serious, and can be consumed with the belt. At this time, the brightness of the coating can be restored to the solution, which can be processed according to the new process. The component content is required to be added, that is, the conversion is completed.

2.Optimization of sulphate galvanizing

The biggest advantage of sulphate galvanizing is that the current efficiency is up to 100% and the deposition rate is fast, which is unmatched by other galvanizing processes. Because the plating crystal is not detailed enough, the dispersing ability and the deep plating ability are poor, so it is only suitable for electroplating of pipes and wires with simple geometric shapes. The sulphate electroplating zinc-iron alloy process optimizes the traditional sulphate galvanizing process, leaving only the main salt zinc sulphate, and the remaining components are discarded. In the composition of the new process, an appropriate amount of iron salt is added to form a zinc-iron alloy coating on the original single metal coating. The reorganization of the process not only carries forward the advantages of high current efficiency and fast deposition rate of the original process, but also greatly improves the dispersing ability and deep plating ability. In the past, complicated parts could not be plated, and now simple and complicated parts can be plated, and the protective performance It is 3 to 5 times higher than single metal. The production practice proves that for continuous plating of wire and pipe, the plated grain is finer and brighter than the original, and the deposition rate is fast. The thickness of the coating reached the requirement within 2 to 3 minutes.

3.Unique clean production

The galvanized pipe adopts the sulphate electroplating zinc-iron alloy process, in which the production line groove and the groove are pierced straight through without any carry-over or overflow of the solution. Each process in the production process consists of a circulation system. Each tank solution is an acid-base solution, a plating solution, a light-emitting and a passivation solution, etc., and only recycles and leaks to the outside of the system, and only 5 cleaning tanks are used in the production line. Reuse of regular discharge, especially in the production process without waste water after passivation.

4.Particularity of electroplating equipment

The electroplated copper wire of the galvanized pipe is the same as the continuous plating, but the plating equipment is different. The wire is designed with a slender strip shape and the groove is long and wide. When electroplating, the iron wire is pierced from the perforation and is in a shape of a straight line on the liquid surface to maintain the mutual spacing. The galvanized pipe is different from the wire, and its unique features, the tank equipment is more complicated. The tank body is composed of upper and lower parts, the upper part is a plating tank, and the lower part is a solution circulating storage tank, forming a tank body with a narrow upper and a lower width and a trapezoidal shape, and a plating passage of a galvanized pipe plating operation is arranged in the plating tank steel pipes manufacturer. The bottom of the groove has two through holes communicating with the lower storage tank, and forms a plating liquid circulation multiplexing system with the submerged pump. Therefore, the galvanized pipe is the same as the wire plating, and the plated parts are dynamic, and unlike the wire plating, the plating solution of the electroplated galvanized pipe is also dynamic.

5.Fast deposition rate and excellent protection

The current efficiency of sulphate electroplating zinc-iron alloy is up to 100%. The deposition rate is unmatched by any galvanizing process. The running speed of fine tube is 8~12 m/min, and the thickness of coating is 2m/min. This is difficult for continuous galvanizing. Achieved. The coating is bright and pleasing to the eye.

The “four-piece cotton” usually refers to the four-piece bedding set in people’s daily life. The four-piece cotton set is: quilt cover *1 bed sheet *1 pillowcase *2 together combined into four sets of cotton Quilt Core Manufacturers(material is mainly cotton.)

Common fabric of “four-piece cotton”

1.Satin jacquard fabric

The difference between jacquard and ordinary printed and dyed fabric: the common printed fabric is printed on the fabric with various bright patterns, while the fabric itself has no pattern and color. Because the color pattern is printed and dyed, it will As the number of cleanings increases, it becomes white or gray, and the jacquard fabric is the fabric manufacturer who weaves the flowers on it. Therefore, its flower patterns are unlikely to be washed away by water, and their requirements for raw materials are relatively high. Density should be more dense (relative to the quality of the work in the weaving process to cut corners, there will be no original appearance, which is also a certain factor in the choice of the clarity of the pattern at the time of purchase) the biggest advantage of the jacquard fabric It is a natural color, simple, and easy to match with furniture. It is comparable to ordinary printed fabrics.

Four-piece cotton

2.Brushed fabric

The sanding fabric is a kind of high-grade combed cotton, which is dyed and finished first, and then exquisitely sanded and crafted. It is soft, comfortable, rich in texture, strong in drape, easy to care, and full of suede. It attracts consumers especially when it is used. It is a warm, soft and comfortable feeling. The color is as new as ever because of The craftsmanship is unique, the sanding bedding will not fade and pilling, it is much better than the average cotton fabric, and the weight is much heavier than the average cotton material. The thick and soft makes you love it; the printing and dyeing method uses active printing and dyeing, the color is bright and will not fade the ball!

3.Long-staple cotton

The difference between long-staple cotton and other cotton is like the difference between cashmere and wool. Long-staple cotton is native to South America and later spread to the southeastern coastal islands of North America, hence the name Sea Island Cotton. Long-staple cotton is a raw material for the development and production of fine, fine and thin high-grade new textiles. Its inherent quality is good (the fiber body length is 33mm or more, the fiber specific strength is 27g/tex or more, and the micronaire value is 3.5-4.2). The price is 1.6 times or more of ordinary fine cotton, which is mainly used for spinning high count yarns, and its product added value is high. Compared with fine-staple cotton, long-staple cotton has the characteristics of low output, high value and increasing demand. The quality of Xinjiang long-staple cotton is excellent, and all quality indicators exceed the national standards. It is especially good in Turpan, its fiber is long, white and shiny, and its elasticity is good. The world’s long-staple cotton producing areas are in the United States, Egypt, and China. China’s Xinjiang output is about 70,000 tons, while the domestic annual demand is more than 150,000 tons, and there is a trend of increasing year by year. As the only long-staple cotton producing area in China, Xinjiang is only suitable for planting in the Turpan Basin and the Tarim Basin in Aksu, Bayingo, Mongolian Autonomous Prefecture and parts of Turpan.

4.Small jacquard active printing

Satin satin + active printing: due to the use of 100% combed cotton as the fabric, authentic 133*72 high-density fabric, so it is particularly soft in hand; full-active printing and dyeing, will not fade the pilling; exquisite printed twill pattern ,meticulous work. Only the small jacquard fabric is called because the front of the quilt is the jacquard process, and the reverse side is the printing process. Compared with the general active printing and dyeing, the craft has improved, and the comfort and feel of the fabric are higher.

5.Jacquard active printing

The jacquard case formed by the warp and weft changes during the weaving of the jacquard fabric has a fine yarn count and is extremely demanding on the raw cotton.
