Description
Technical field
The present invention relates to electric power protection Manifold technology field, particularly relate to a kind of fire-retardant electric power protection pipe.
Background technology
Pvc pipe has good tension, ultimate compression strength, but it is flexible not as other plastics tubings, excellent corrosion resistance, price is the most cheap in all types of plastic pipe, but more crisp under low temperature, resistance toheat is given prominence to, and heat-drawn wire is 100 ° of C, chemical resistance is excellent, for the water supply and sewage, irrigation, air feed, exhaust pipe, wire tube, rain pipe, industrial antisepsis pipe etc. of house life, industry and mining, agricultural.PVC major ingredient is polyvinyl chloride, adds other one-tenth in addition and assigns to strengthen its thermotolerance, toughness, ductility etc.The production of China's plastics tubing and application, gap is not little compared with advanced country, development is need in a lot of application aspect, be eager to wait for that we go developing, as the conveying of the exploitation of gas line, the laying of city buried pollution discharge pipe, oil and gas, the laying of communication cable and field irrigation water saving jet pipe dropper.The 60%-70% of whole plastics tubing total amount is accounted at these plastics tubing application quantities being related to China city and national development, but the plastics tubing manufacturing enterprise really entering into this field is less than 30%, compared with advanced international standard, also there is larger gap in China's PVC heat stabilizer, is mainly manifested in the aspects such as kind is few, production structure is unreasonable, industrial scale is little, industrial concentration is low; Proposing Chinese PVC stabilizer should to low toxicity, pollution-free, compound, the future development such as efficient.China PVC novel material is produced and is started from the eighties, and be limited to the state of the art of domestic this locality at that time, the development of PVC profile is always slower.The policy used along with a series of restriction timber of later stage government is put into effect, and the market of PVC profile is opened.From the demand distribution of pvc, China pvc resin constantly changes in the application percentage in each field, and soft goods consumption proportion declines year by year, and the hard product consumption proportion that profiled material, tubing, sheet material etc. are mainly used as material of construction improves constantly.Pvc soft goods kind is a lot, except film, leatheroid, electric wire, also has wallpaper/foam material and flooring laminate, and the pvc amount of this two classes field consumption in 2013 will reach 230,000 tons and 320,000 tons respectively.Current China pvc boardy product consumption proportion rises to 59.2%, but still has certain gap compared with developed countries.Therefore, the goods such as tubing, profiled material will be the main growth factor of pvc consumption from now on.
