Abstract
The utility model discloses an ultrahigh molecular weight steel-belt strengthened composite plastic pipe, which relates to a plastic pipe. The composite plastic pipe comprises an inner wall layer and an outer wall layer, wherein a high-strength plastic steel belt layer soaked with a high-strength adhesive is arranged between the inner wall layer and the outer wall layer and is formed by combining a wound steel belt and a high-molecular adhering layer. The composite plastic pipe provided by the utility model has high wear resistance; the wear resistance of UHMWPE (Ultrahigh Molecular Weight Polyethylene) is number one among current plastics, and is 4 times higher than that of nylon 66, 10 times higher than that of high-density polyethylene, 4-7 times higher than that of a carbon steel pipe and nearly 10 times that of a stainless steel pipe; and the composite plastic pipe has pretty high impact resistance and corrosion resistance and is free from scaling.
Description
Technical field
The utility model relates to a kind of plastic tube, relates in particular to a kind of super high molecular weight steel strip reinforced composite plastic pipe.
Background technique
" 12 " are that the plastic processing industry is formed a connecting link and realized the critical period of great-leap-forward development.The Plastics Processing Industry gross output value in 2010 is GDP3.35%, also has certain distance from 5% generally held standard, but the domestic huge market demand and development space will make Plastics Processing Industry continue to continue to increase rapidly, Plastics Processing Industry has further promoted the status in national economy as the characteristics of rising industry fast development.Plastics Processing Industry ought to be paid much attention to, and should strengthen the cultivation dynamics, made it to grow into sooner one of pillar industry in national economy.
The plastic pipe target that clear and definite " 12 " reach in " national chemical building material industry the Tenth Five-Year Plan (2001-2005) and development planning outline in 2015 ", by 2015, the applying mainly take polyethylene pipe as main of plastic tube, and greatly develop novel plastics pipe.In the newly-built, renovating and enlarging engineering in the whole nation, New Dwelling indoor drainage pipe 85% adopts plastic tube, substantially eliminates traditional cast iron tube.Wiring architecture wiring sheath pipe 90% adopts plastic tube, and building rainwater drainage pipe 80% adopts plastic tube; Building water supply, hot water supply and heating pad pipe 85% adopt plastic tube, substantially eliminate Coating Steel Pipe.City supply water pipeline DN400mm following 80% adopts plastic tube, and villages and small towns water supply line 90% adopts plastic tube, and the application quantity of gas plastic tube reaches 40%, and the plastic tube use amount of urban discharging pipeline reaches 50%.But numerous polymer material in the market, friction factor is large, wears away highly, and chemical proofing is poor, and shock-resistant, resistance to pressure, frost resistance, heat insulating ability, self lubricity, ant-scaling, stress cracking resistance, wholesomeness etc. are all undesirable.
Summary of the invention
The utility model is intended to for the deficiency that exists in the background technique, and a kind of super high molecular weight steel strip reinforced composite plastic pipe that provides.
Super high molecular weight steel strip reinforced composite plastic pipe of the present utility model is to be made of inner wall layer and outer wall layer, and the high strength that is soaked with the high strength binder between inner wall layer and outer wall layer is crossed the plastic-steel belt.
As further improvement of the utility model, it is to be wound in inner wall layer and to be merged with the macromolecule gluing layer by the steel band interval that is no less than to consist of that described high strength is crossed the plastic-steel belt.
As further improvement of the utility model, described inner wall layer is the ultra-high molecular weight polyethylene raw material.
As further improvement of the utility model, described outer wall layer outer pipe wall be high-density polyethylene layer and ultra-high molecular weight polyethylene layer any one.
Super high molecular weight steel strip reinforced composite plastic pipe of the present utility model has high wear resistance, impact resistance, good internal pressure strength, environmental stress crack resistance, good selflubricating, anti-adhesive, unique lower temperature resistance, the good superior functions such as chemical stability, is widely used in metallurgical mine, electric power, oil, rock gas, weaving, papermaking, food, chemical industry, machinery, the industry such as electric.Have following clear superiority:
1, high wear resistance
The wear resistance of UHMWPE occupies the hat of existing plastics, and is higher 4 times than nylon 66, higher 10 times than high density polyethylene (HDPE), than the high 4-7 of carbon steel tube doubly, than Stainless Steel Tube near 10 times;
2. high impact properties
It is the first that the impact strength of UHMWPE ranks existing plastics, uses common test method, be difficult to make its rupture failure, and the surface hardness after the lower impact of temperature is higher on the contrary;
3. corrosion resistance
The UHMWPE pipe has good chemical proofing, except the strong oxidizing property acid solution, in certain temperature range except the various Korrosionsmedium acid of ability, alkali, salt and the organic media naphthalene solvent;
4. non-scaling
UHMWPE adsorption power very a little less than, its anti-adhesion ability is only second to teflon, be difficult for to adhere to other materials, non-scaling;
5. self lubricity
UHMWPE is rich in self lubricity, and friction factor is extremely low.Therefore flow resistance is very little, can keep for a long time flow velocity and flow not to subtract;
6. lower temperature resistance
Resistance to low temperature is excellent, and its impact resistance, wear resistance are substantially constant in the time of subzero 269 degrees centigrade.The present unique a kind of engineering plastics that can under the temperature near absolute zero point, work.Simultaneously, the thermophily of this product is wide, can work under-269 ℃ to 80 ℃ temperature for a long time;
7. noise reduction
Ultra-high molecular weight polyethylene impact energy absorptivity is peak in the plastics, and noise reduction is good, thereby has reduced to greatest extent the noise that flow of fluid produces in course of conveying;
8. health, nontoxic is not gone mouldy, and breed bacteria, health do not meet the index of national Specification, but contact food and medicine;
9. lightweight, easy for installation
The density of UHMWPE only is about 0.94g/cm3, and proportion is the sixth of steel pipe weight only, make loading and unloading, transportation, install more convenient;
10. connect
The employing Flange connects, and need not spacer block, connects safe and reliable, efficient and convenient, need not anticorrosion, save labor, demonstrate fully the superiority of using superhigh molecular weight polyethylene pipe road " energy-saving and environmental protection, economy, efficiently ".
