Without manganese wear resistant coating, how dare you say that your elevator wire rope is of the be

When any business sells it, it will advertise that the products they produce perform the best, that's for sure. For wire ropes, the most reliable way to compare the comprehensive performance of two wire ropes is fatigue test, and the longer the fatigue life, the longer the service life. Manganese phosphating film is a kind of wear-resistant protective coating, after the steel wire is phosphated by manganese, the surface of the steel wire is extremely wear-resistant, and the anti-corrosion ability is greatly improved at the same time, therefore, the fatigue life of the manganese phosphate coating elevator wire rope is three to four times that of the fatigue life of the smooth elevator wire rope, which is better and which is inferior at a glance, if there is a fatigue testing machine, it is recommended to measure the fatigue life and compare the test results.

Manganese phosphate coated wire rope is an upgraded product of all kinds of smooth wire rope, some enterprises have obtained patent licenses, and have produced manganese phosphate coated wire rope in large quantities, and the market is in short supply.

Manganese phosphate film is a kind of wear-resistant coating, at present, the strongest wear resistance is the manganese phosphate coating wire rope under a national standard, an industry standard, is the method of determining the fatigue life of the wire rope, at present, the best fatigue resistance is the manganese phosphate coated wire rope, wear resistance, corrosion resistance, a factory manganese phosphate coating elevator wire rope fatigue life has reached 2.8 million times, the ordinary smooth elevator wire rope is only 600,000 times, the quality is poor, it is more than 400,000 times, This illustrates the quality gap, the longer the fatigue life of the wire rope, the longer the service life of the wire rope, they are proportional.

The smooth elevator wire rope is directly twisted with smooth steel wire, without any wear-resistant and anti-corrosion coating treatment. At present, only the manganese phosphate coated elevator wire rope is the first to make the rope wire to do wear-resistant and anti-corrosion treatment, because the wear-resistant and anti-corrosion ability of the steel wire has been greatly improved, and the fatigue life of the manganese phosphate coated elevator wire rope is 3-4 times that of the smooth elevator wire rope, which is the most cost-effective and the most advanced technology today.

The manganese phosphate film itself is wear-resistant, and after adding grease, the wear-resistant and anti-rust effects are very good, and it is not easy to wear and rust, so that its fatigue life is about three times that of the smooth wire rope. Commonly used wire rope varieties are phosphate-coated wire rope, galvanized wire rope, stainless steel wire rope or plastic-coated wire rope, which is used in atmospheric environments, and the manganese phosphate coated wire rope produced by patented technology has the longest service life, and hot-dip galvanized-phosphated double-coated wire rope is preferred in heavy corrosive environments.

The use of smooth wire twisting is the smooth wire rope, the surface of the smooth wire is not any kind of wear-resistant coating, the smooth wire is easy to wear and fatigue breakage, the fatigue life of the smooth wire rope is relatively short. Wear-resistant phosphate coated wire rope is currently the only kind of wire rope with wear-resistant protective coating in the world, the fatigue life is three to five times that of the smooth wire rope, the service life is longer, the cost performance is higher, and the wire rope with long fatigue life is the best fatigue resistance. Slings made with wear-resistant phosphate-coated wire ropes are also resistant to wear and corrosion, and have a longer service life.

The manganese phosphate film on the surface of the steel wire weighs 15-30 grams square meters, which can prevent fretting wear and oxidation and rusting of the steel wire, and the fatigue life of the manganese phosphate coated elevator wire rope is three to five times that of the smooth electro-buried Biti wire rope, if the company has a fatigue testing machine, it is highly recommended to measure the fatigue life and then compare the test results. The protective effect of manganese phosphate film is more than bending late lifting every day to oil the wire rope maintenance, manganese phosphate coated wire rope is an authentic high-quality long-life product, smooth wire rope is not any wear-resistant protective coating, smooth wire rope is a backward process production of eliminated products, when buying manganese phosphate coated wire rope, pay attention to the patent number, many enterprises have obtained patent licenses to produce manganese phosphate coated wire rope, note that the phosphate film weight is less than 3 grams of denxin square meters is not manganese phosphate coated wire rope, Pay attention to screening to prevent being deceived.

Manganese phosphating wear-resistant coating wire rope is now the world's only wire rope product with wear-resistant protective coating, China invention patent, rope wire surface has 15-40 grams of square meters of manganese phosphating film is wear-resistant protective coating, can prevent steel wire from fretting wear and rust oxidation, service life is greatly improved, longer service life, lower average daily use cost, is a variety of smooth wire rope upgrade products, popular by users, in order to prevent buying fakes, pay attention to the following two points, Domestic production enterprises that have obtained patent authorization licenses, in the manganese phosphating wear-resistant coating wire rope packaging wooden shaft is generally sprayed with a patent number, in the State Intellectual Property Office Patent Office ** or CNKI can be retrieved "phosphating coated wire rope" patent number, and the wooden shaft can be compared above, the second is to test the manganese phosphating film is small, the phosphating film weight should be in line with the agreement with the manufacturer, generally 15-40 grams of phosphate wear-resistant coating, less than 3 grams of square meters is not the real manganese phosphating wear-resistant coating wire rope. All kinds of smooth wire ropes belong to the backward process elimination products, because the smooth wire rope is easy to wear and break the wire, and the fatigue life is relatively short.

Smooth elevator wire rope is not any kind of wear-resistant protective coating, after the use of rope-making wire, it is very easy to occur fretting wear, and then induce fatigue breakage, smooth elevator wire rope fatigue life is relatively short, manganese phosphating wear-resistant coating wire rope is the only wire rope in the world with wear-resistant protective coating, because it is a newly developed technology, belongs to China's invention patent, as long as the patent authorized enterprises can be legally produced, so there are only five or six domestic enterprises to produce. The national standard is the minimum standard of product quality, and all the advanced technology involving patents is not reflected in the national standard, that is, there is no technical requirement for the wear-resistant protective coating of steel wire in the national standard.

Manganese phosphating wear-resistant coating elevator wire rope, the thickness of the manganese phosphating wear-resistant protective coating on the surface of the steel wire is very important, the domestic patent licensing enterprises are generally controlled at 15-30 grams of square meters, the greater the weight of the phosphate film the longer the fatigue life, which can be verified by fatigue test.

Phosphate coated wire rope is a patented technology, which can be used to produce elevator wire rope, that is, phosphate coated elevator wire rope, manganese or zinc-manganese phosphate coating is preferred, both of which can greatly improve the wear resistance and corrosion resistance of the wire surface, thereby inhibiting the occurrence of fretting fatigue, and the fatigue life is 3-4 times that of the smooth wire rope with the same structure, with the research on wear-resistant phosphate coating, there is the possibility of further improvement. The broken wire and wear during the use of the elevator wire rope can be identified by the naked eye, and the magnetic flux leakage method can also be detected by the instrument, and the detection technology has matured. Phosphate-coated wire rope with longer service life, lower cost of use, higher safety and stability.

The traction steel belt is the use of a plurality of galvanized steel wire ropes, covered with a layer of polyurethane, polyurethane steel belt is expensive, the detection of polyurethane inner wire rope broken wire rope requires special instruments, internal broken wire is a potentially significant risk, must be accurately measured, in order to determine whether the traction steel belt needs to be scrapped and updated. The friction factor between the traction steel belt and the traction wheel is large, and the elevator runs smoothly.

To better meet the requirements of users is more advanced technology, users hope that the longer the service life of the wire rope, the better, the lower the unit cost of use, the better, therefore, the longer the service life, the more advanced its manufacturing technology. Fatigue test proves that the manganese phosphate film on the surface of the steel wire weighs 15-30 grams square meters, the fatigue life of the manganese phosphate coated elevator wire rope is three to five times that of the smooth elevator wire rope, the larger the weight of the steel wire phosphate film is the longer the fatigue life, many domestic enterprises have obtained patent licenses, which is in accordance with the weight range of the phosphate film to organize the production, through the fatigue life test results, it is obvious that the manganese phosphate coated wire rope is an advanced technology, and the smooth wire rope is a product that is being eliminated.
