What is Ethylone?

The ethyl group is a colorless transparent liquid. A special stimulating odor. With sweet. Extremely volatile. The steam is heavier than air. In the role of the air can be oxidized into peroxides, aldehydes and acetic acid, exposure to light can promote its oxidation. When the ether contains peroxide, the evaporation of residual peroxide after heating to 100 ° C or more can cause a strong explosion; these peroxide can be added 5% aqueous solution of ferrous sulfate shake removed.
Ethylone mainly used as oil, dyes, alkaloids, fat, natural resin, synthetic resin, nitrocellulose, hydrocarbons, linseed oil, petroleum resin, rosin, spices, non-vulcanized rubber and other solvents. The pharmaceutical industry for the production of pharmaceutical extractant and medical anesthetic. Wool, cotton spinning industry as oil cleaners. Gunpowder industry for the manufacture of smokeless powder.

The reinforcement of heavy goods lashing

Binding of major pieces of goods, first of all to correctly select the lashing rigging. Commonly used lashing rope with fiber rope, wire rope and chain, and with the elastic screws, shackles, etc. used together. Lashing of large pieces of goods should use steel wire rope and chain. The use of chain lashing convenient, fast, but not easy to tighten; use of wire rope is easier to tighten the banding, but no chain convenience, each pros and cons, should be selected according to specific circumstances.
Large pieces of goods lashing should also pay attention to the following questions:
1. Lash tightness should be appropriate. Requirements lashing fastening, not to loose, but also to prevent too tight break. But also easy to unlock, so that in case of an accident can be relaxed immediately.
2. Improve the banding effect, saving cable ties. For this purpose, the banding angle should be as small as possible, and should be balanced.
3. To ensure that shipments from injury. In order to avoid the direct contact with the cargo surface, pressure loss or wear goods, should be in the required parts of the banding, if necessary, should be added in the banding site bedding. For the fear of wet goods, in addition to a reasonable choice of goods, the banding should be covered with tarpaulins before, easy to corrosion parts should be coated with protective grease.
4. Lashing process to be correct. Binding should be around, symmetrical. Each rope should be around the first shipment of goods on both sides of a week and then fixed, can not be tied to a multi-channel cable. Each root to make no more than three rope, and the direction can not be the same. For vehicles such as pulleys of goods, generally should first use sleepers bedding, upper rail, between the wheels and rail to use triangular iron fixed, and the triangle should be welded on the rail. Installed in the cabin of the major pieces of goods, in addition to fixed with the cable, the general should also be vertical and horizontal direction with the wooden side to withstand, between the pieces of wood are also pegged to prevent shift on the way.

Investigation on the Current Situation of China Textile Machinery Parts Market

The first human use of natural fibers as raw materials, spinning and weaving, as early as the invention of the text (see the world textile history, the history of Chinese textile). China in spring and autumn and the Warring States period has been using hand spinning spinning, to the Song Dynasty has invented more than 30 spindle hydraulic large spinning wheel. In 1769 the British R. Ake Wright) (also translated Richard? Arkwright) manufacture of hydraulic spinning machine. 1779 British S. Crompton (Samuel Crompton) invented the spinning machine. After the introduction of the United States, 1828 American J. Thorpe invented the ring spinning machine, the use of continuous spinning to improve productivity several times. China's Warring States period has been the use of leverage loom principle to drive the heald frame connecting rod to complete opening action.
According to the China Industrial Research Network released the China Textile Machinery Parts Market Research and Development Prospects Report (2015-2020) shows that textile machinery manufacturing industry is divided into two categories: one is to create the whole machine, and the other is the manufacturing Special parts (such as spindle, cradle, ring, wire ring, needle, card clothing, healds, menopause, etc.). The entire textile machinery factory equipment for the whole plant equipment accounted for a small proportion, so under certain conditions can change the variety of production of other machinery. Manufacture of special parts for the factory-specific equipment, a larger proportion of special lines (especially the needle, card clothing), change varieties more difficult. In the various types of work, casting the proportion of gradually narrowing, cold stamping, grinding, electroplating, polishing and so the proportion gradually increased. CNC machine tools, multi-position automatic machine to replace local special machine, so that the production of adaptability, flexibility enhanced.

ALL OF TRAFFIC LIGHTS IN DUBAI WILL BE REPLACED OF LED LIGHTING

As Dubai transportation officials Maitha bin Udai said that all of traffic lights in Dubai will be replaced of led commercial light bulbs, these projects will realize the effect of about 55% energy saving, 900 thousand of Dirham saving per every year. the new style of led lightings can realize more the uniform distribution of light, and automatically adjust the light intensity according to the the external light intensity, it will help them to reduce traffic accidents.
