Rubber gloves - wholesale in Ukraine
In this article I want to tell You about what are rubber gloves, the materials of which they consist, and where and how profitable to buy. First and foremost, this article is perfect for the buyer businesses that still do not know what about rubber gloves.
Let's look at what is the concept about rubber gloves there is a perception among buyers. I asked our sales managers work gloves company, asking the question: what do you mean buyers under the concept of rubber gloves. It turned out that the buyers under the term attribute most of working gloves, knitted gloves with PVC coating, latex household gloves, nitrile disposable gloves, the gloves are fully or partially covered PVC, neoprene gloves. And I wondered: what is rubber at all? His answer I found in the encyclopedia which literally interpreted the word rubber as:
Rubber when translated from Latin means resin, and is a stretch material that is produced with vulcanized rubber. Rubber has found its use in many products, for example from it produced tyres for cars, buses, bicycles, all kinds of hoses, rubber gloves, conveyor belts, and medical and household products, and others.
The rubber industry consists of a process of obtaining from a natural or synthetic rubber vulcanized - mixing with vulcanizing agent (usually with sulfur), followed by heating. Rubber can be of different types, and the degree of vulcanization of the rubber is divided into mild (1-3% sulfur), and semi-solid (30 % sulfur). A density of about 1200 kg/m3.
His history of rubber begins with the moment of the discoverers of the American continent. And even before the pioneers of the local population of America from the milky juice of rubber trees were rubber. This famous discoverer Columbus noticed that the Indians use some strange balls in play and they are very well bounce, better known to Europeans than leather. In addition to the rubber balls used in everyday life: making tableware, seal the bottoms of boats, creating a waterproof stockings, it is worth noting that the method was quite painful so as the legs have rubber covered ground and held over the fire, the result was a waterproof coating; used rubber and glue: with the help of it the Indians were glued feathers to the body for decoration. But the message of Columbus about an unknown substance with unusual properties remained unnoticed in Europe, although, of course, that the discoverers and first settlers of the New world widely used rubber.
Rubber has been demonstrated in Europe researcher Ketaminom in 1738 in France. Codemin showed the way of obtaining rubber. But unfortunately the first use for rubber was not. And the first time the rubber began to be used to erase the pencils, and so long eighty years. This was due to the fact that the tires quickly dried and hardened.
Many years later a method was found the return rubber elasticity, this method was invented by the chemist Mac. Later Macintosh invented a waterproof fabric which result from the impregnation of a dense fabric of rubber in kerosene. Already from the tissue began to produce waterproof raincoats in the end, carrying the name "McIntosh".
Of disadvantages rubber the most basic was the fact that at low temperatures they have hardened, and at high much softened.
Today rubber has been found in far 1839, a way which helped to stabilize the extensibility and elasticity were found Godjira and consisted in mixing raw rubber with sulfur and subsequent heating. This method is called vulcanization, and is probably the first industrial polymerization process. The product received as a result of vulcanization, called rubber. After the opening of the Goodyear rubber has been widely used in engineering as the different seals and sleeves in the nascent electrical engineering industry which was in dire need of a good insulating elastic material for the manufacture of Cabella. About rubber gloves at the time, neither of which was not mentioned.
Eventually when it started to rapidly develop the mechanical engineering and the automotive industry's increased demand for rubber. With the investigation that gave rise to the new plantations of rubber-bearing trees. Initially the plantations were in South America, and later expanded to Ceylon and Indonesia.
With even more growth of engineering comes the rubber crisis. And the rubber starts to go up. The condition for this is a number of factors: more overhead transport costs, time-consuming process of juice extraction and also the monopoly of some countries, hampering competition. Therefore began the search for alternative sources of rubber. The search was developed in two directions. Looking for those plants which could be raised in colder climates. The second area is the replacement of natural of synthetic rubber. A beginning in this direction was given to the experiments of Faraday on study of the chemical composition and structure of rubber. In one thousand eight hundred and seventy-eighth year Bouchard revealed the reaction of transformation of isoprene in kauchukopodobnoe mass. And in 1910 he discovered the polymerization reaction.
Large volume manufacture of production of synthetic rubber had reached in the Soviet Union, which became the pioneer in this field. This was due to the acute shortage of rubber for a rapidly developing industry, the lack of effective natural chuchkanov in the Soviet Union and restricting the supply of rubber from abroad, since the ruling circles of some countries tried to prevent the process of industrialization of the USSR. The problem of establishing large-scale industrial production of synthetic rubber was successfully resolved, despite the skepticism of some foreign experts.
Used rubber found in the production of all kinds of tyres for cars, buses, trucks, bicycles, wheelchairs. Not enough is produced of rubber and rubber products - is conveyor belts, drive belts, pressure and pressure-savivalda sleeves, durotoye products, technical plates, rubber rings of various seals, vibration isolators and VIBROCONTROL and rubber flooring and rubber footwear such as boots and overshoes. And of course, rubber gloves.
Rubber for its application can be of these types:
- resistant to oil and gasoline
- rubber gloves
Some of the most popular are rubber gloves made of PVC. The most common color of the polyvinyl chloride – red. These gloves consist of knitted cotton basics ending with a elastic at wrist for better grip on hand. For fast and frequent removal Krai make rubber gloves in the form of leggings. All the rubber glove until the gum is covered with a thick layer of PVC. PVC as a material has good resistance to oils and gasoline.
The disadvantage of this material is the low temperature at which it is possible to use these rubber gloves from – 15 C to + 65 C.
The most common material of this type is neoprene. It often happens that he is black. Neoprene gloves can be of different lengths and thickness. Also, these rubber gloves can consist of a combination of neoprene and latex, neporen on the outside and latex inside.
Data gloves:
- resistant to aggressive environments
- resistant to heat
- resistant to different temperatures
- resistant to ozone
In this group the best known is rubber household glove. No specific color in which color these rubber gloves. In addition to resistance to ozomu these gloves do not allow water, oil.
