Description
Technical field
The invention belongs to polymeric material field, and in particular to a kind of low temperature resistant PVC corrugated tubes.
Technical background
Plastic film capicitor is developed in the fifties earliest, and the development advanced by leaps and bounds has been obtained at nearest 20 years.Plastic film capicitor
Special " cannelure " formula special-shaped section form is adopted in structure design, this tubing is novel in design, rational in infrastructure, breaches
" board-like " traditional structure of common tubing, makes tubing both have enough resistance to compressions and an impact strength, and with good flexible
Property.Plastic film capicitor can be widely applied to draining, water-permeable pipe；Interior decoration cable conduct；Automobile electric wire sleeve pipe；Prestressed anchor
Noose pipe；Outlet pipe for air conditioner etc..Plastic film capicitor is the product that synthetic resin doping Jing melt moldings are processed.Add
Plus agent has plasticizer, stabilizer, filler, lubricant, coloring agent, UV absorbent, modifying agent etc..Development and application
In plastic film capicitor, according to the resin used by production plastic film capicitor, the corrugated tube of heterogeneity purposes is obtained, is selecting tree
During fat, should require with reference to the performance of product and moulding process.From the point of view of plastic ripple pipeline market prospect, plastic film capicitor
Road market is covered with huge business opportunity.Corrugated conduit through the expansion of nearly 20 years, at aspects such as equipment, forming technique, technique, PP Pipe Compounds
Rapid expansion is obtained all.And also lagging far behind and foreign countries in the research and development of plastic film capicitor for current China, sell on market
Plastic film capicitor compared with external product, also there are some defects, such as PVC corrugated tubes in performance：Main Ingredients and Appearance is poly-
Vinyl chloride, bright in colour, corrosion-resistant, firm and durable, with preferable tension, comprcssive strength, bonding, the connection of socket joint cushion rubber, method
Orchid is threadedly coupled for house life, industry and mining, the water supply and sewage of agricultural, irrigation, supply, aerofluxuss pipe, electric conduit, rainwater
Pipe, industrial antisepsis pipe etc..Heat resistance is projected, and heat distortion temperature is 100 DEG C, and chemical-resistance is excellent.But its flexibility is not so good as which
His plastic tube, excellent corrosion resistance, price are generally the least expensive in all types of plastic pipe but more crisp under low temperature.For this purpose, we are from product
Formula is set about, the design of the formula of plastic film capicitor will according to the compatibility of the performance of corrugated tube, structure, purposes, auxiliary agent and resin,
Influencing each other between each analog assistant and cooperative effect, and the characteristics of former, the forming factors of comprehensive each side are set
The selection of epoxy-type number and various addition auxiliary agents.In order to meet high request of the market to plastic film capicitor, develop a kind of each
Plant performance preferably PVC corrugated tubes.
