Ultraviolet Irradiation Crosslinking Equipment
Application of UV-light irradiation cross-linked equipment
The UV-light irradiation cross-linking process uses UV-light as the irradiation source, extrudes and coats the mixed photo-crosslinking polyolefin compound on the conductor wire core, and then immediately enters the special irradiation equipment for fused photo-crosslinking. The insulated wire core after light irradiation cross-linking can be produced into photo-crosslinking polyolefin insulated wire and cable products through cooling treatment at different temperatures and other subsequent processing.
UV-light irradiation cross-linking method needs to be slightly modified only on the original normal extrusion production line. The upper traction, irradiation box and electric control cabinet with a small floor area can meet the operating requirements and produce UV-light irradiation cross-linked polyethylene wire and cable products. The addition of upper traction enables the conductor wire core to maintain a certain tension. In the running process, it shall be always in the center of irradiation box to ensure the best irradiation effect. The irradiation box uses a reflective focused UV light source that is uniformly configured and specially designed, and the electrical control system will ensure that the UV-light intensity and the irradiation temperature in the center of the irradiation box are in the optimum operating conditions. In addition, the efficient photo-initiation system rapidly induces cross-linking reaction of polyolefin under the UV-light irradiation, so that the irradiation equipment can reach a continuous production speed of dozens of meters per minute, and gradually cools at hot, warm and cold temperatures to ensure the stability of three-dimensional cross-linked netlike structure.

TAIC is widely used as a coagent for peroxide crosslinking or radiation crosslinking of Chlorinated Polyethylene (CPE), EPDM, Fluroelaster and so on.TAIC is availavle for linking by x-ray, y-ray electron or ultra violet ray radiation and the product polyolefines have the superior insolubility to solvents and the tensile strength at high temperature could be improved.TAIC is effective modifier to heat resistance with increasing of crosslinking density for peroxide crosslinking denisty for peroxide crosslinking of CPE. Since TAIC acts as an acceptor of HCI which is envolved from CPE at crosslinking reaction and deteriorates its physical properties.TAIC is the most effective coagent for crosslinking EVA.TAIC preferably contributes to promote crosslinking rate and also to improve its heat resistance, compression set and abrasion resistance

SULFUR GRANULES SULPHUR LUMPS
Sulfur is one of the most important agricultural and industrial raw materials and is considered a strategic product sulfur is an odourless, tasteless and polyvalent nonmetal which is mostly in the form of yellow crystals and is obtained from sulphide and sulphate. Sulphur occurs naturally in the environment and is the thirteenth most abundant element in the earthâ??s crust. It can be mined in its elemental form, although this method has declined over the last decade to less than 2% of world production. Today most elemental sulphur is obtained as a co-product recovered from oil and gas production in sweetening process.
Sulphur is the primary source in the production of sulphuric acid, the world's most widely used chemical. Sulphuric acid is an essential intermediate in many processes in the chemical and manufacturing industries. Sulphuric acid also is used by the fertilizer industry to manufacture primarily phosphates, nitrogen, potassium, and sulphate fertilizers.
Sulfur reacts directly with methane to give carbon disulfide, used to manufacture cellophane and rayon. One of the direct uses of sulfur is in vulcanization of rubber, where polysulfide chains crosslink organic polymers. Large quantities of sulfites are used to bleach paper and to preserve dried fruit. Many surfactants and detergents (e.g. sodium lauryl sulfate) are sulfate derivatives. Calcium sulfate, gypsum, is mined on the scale of 100 million tonnes each year for use in Portland cement and fertilizers. Sulphur is increasingly used as a component of fertilizers. Sulfur can be used in agriculture and various industries such as plastics and many synthetic products, paper, paint, etc.
