Abstract

The invention relates to an electrically melted socket-type fiber glass reinforced plastic drain pipe and a manufacturing method thereof. The electrically melted socket-type fiber glass reinforced plastic drain pipe not only has the characteristics of a plastic pipe, but also has the characteristic of high ring stiffness of a metal pipe. The electrically melted socket-type fiber glass reinforced plastic drain pipe has the advantages that: 1) compared with similar plastic pipes, the pipe has the characteristic that 30 percent of polyethylene (PE) materials are saved; 2) the pipe is convenient to connect, only 1000RMB is required to be invested in connecting equipment and the connection of one pipe can be completed within 17 minutes; 3) the connection reliability is high and the goal of 100 percent of no leakage is achieved; 4) the cost is low and is 30 percent of the plastic pipe with the same performance and the service life and anticorrosive property are more than five times of the service life and anticorrosive property of cement pipes; 5) since an electric heating fuse is embedded in the pipe wall, the electric heating fuse does not fall off during socket construction; 6) the pipe can adapt to severe construction conditions and the excavated volume for construction is small; 7) the ring stiffness of the pipe is high and the amount of used materials is small; and 8) since the pipe is made of plastics and glass fibers, the pipe is not corroded by sewage.

Description

A kind of electric smelting spigot and socket type glass strengthens waste pipe and production method

Technical field

The present invention relates to the structured wall plastic pipe that a kind of glass strengthens, belong to drainage pipe and make the field.

Background technique

The steel band reinforced pipe adopts steel plate as internal layer on structural design, improves the ring stiffness of intake-discharge pipe with this.Its deficiency: one of which, connect unreliable and constructional difficulties, manufacturing efficiency low; Its two, the plastic layer on shaped steel surface can separate with steel band, makes the steel band corrosion.

Double-wall corrugated pipe adopts PE plastic shaping structure-wall pipe material, to improve its ring stiffness.Deficiency: the ring stiffness is lower, and equipment investment reaches pipe diameter greatly and is not easy to do greatly.

The carat pipe on structural design, adopts the PE hollow tubular to cover and moulds enhancing, improves draining pipe ring stiffness with this.Its deficiency: product cost is high, is difficult to bear; Be prone to come off in the construction of electric heating fuse and make construction quality be difficult to guarantee.

Summary of the invention

Purpose of design: avoid the deficiency in the background technique, design a kind of plastic tube characteristic that both had, can accomplish high ring rigidity again, price is also cheap.

Design proposal: in order to realize above-mentioned purpose of design.Sneak into the 0-40% glass in the plastics of electric smelting spigot and socket type glass enhancing waste pipe; Because glass has very high stiffness, has improved the characteristics of the low elastic modulus of plastics, empirical tests; Under the topic condition, the pipe that contains glass is littler by 30% than every meter weight of pure PE pipe before identical ring stiffness.Simultaneously, common short glass fiber low price only is equivalent to 20% of plastics price.Therefore, product price is merely carat (40-45) % of pipe.

The purpose of doing like this is: plastic tube wall has good anti-corrosion, and it can prevent the corrosion of underground sewage effectively, and does not have leakage problems; Strengthen and add glass, the ring stiffness of plastic tube significantly improves, price decline (40-45) %; Adopt embedded electric heating wire socket joint to connect and guarantee that 100% is non-leakage.Both solve the deficiency that background technique exists thus, realized purpose of design of the present invention again.

Technological scheme 1: a kind of electric smelting spigot and socket type glass strengthens waste pipe, it is characterized in that: said electric smelting spigot and socket type glass strengthens waste pipe and in the plastics of tubing, adds glass.

Technological scheme 2: at first plastics are mixed with glass, extrude and be the plastic tape that band shape contains glass and be wrapped on the cylindrical die material of rotation, continuous uninterrupted is twined and is made it to be fused into an integral body.Meanwhile; The mould of another outlet of extruder is extruded the plastic tube that contains glass in a tubular form; In the glass fiber plastic pipe, be inserted in the PP bushing pipe; The plastic tape that contains glass that makes it to extrude with the front is wrapped on the die material simultaneously, and plastic tube that contains glass and the plastic tape that contains glass are bonded together.Continuously produce, the outside that strengthens waste pipe at electric smelting spigot and socket type glass forms the helical stiffening rib, and stiffening rib is distributed in 98% interval, pipe middle part, and its two ends are respectively the bellmouth and the socket of no stiffening rib.Through cooling and shaping, machine tooling is shaped on female end and the socket end, and the product after the processing carries out the demoulding through stripper.

The present invention compares with background technique

1, compare with the steel band reinforced pipe, it is easy to connect that electric smelting spigot and socket type glass strengthens waste pipe, low price, do not have steel and mould segregation phenomenon.

2, compare with double-wall corrugated pipe, electric smelting spigot and socket type glass strengthens big, easy to connect, the low price of draining pipe ring stiffness, and the pipe price of DN1000 is double-wall corrugated pipe price 50% only.

3, with carat pipe relatively, electric smelting spigot and socket type glass strengthens that draining pipe ring stiffness is big, low price, electric heating fuse do not come off.With the DN1600 pipe is example, price only carat pipe 40%.

4, with socket joint electric smelting jointing type steel band reinforced polyethylene spiral ripple pipe relatively, the electric heating fuse does not come off, and does not have that steel is moulded segregation phenomenon, price is more cheap.

Embodiment

Embodiment 1: strengthen waste pipe with reference to 1 one kinds of electric smelting spigot and socket type of accompanying drawing glass, it comprises bellmouth, socket, spiral reinforcing rod, spiral heating silk.

Embodiment 2: on embodiment 1 basis, at first plastics are mixed with glass, extrude and be the plastic tape that band shape contains glass and be wrapped on the cylindrical die material of rotation, continuous uninterrupted is twined and is made it to be fused into an integral body.Meanwhile; The mould of another outlet of extruder is extruded the plastic tube that contains glass in a tubular form; In the glass fiber plastic pipe, be inserted in the PP bushing pipe; The plastic tape that contains glass that makes it to extrude with the front is wrapped on the die material simultaneously, and plastic tube that contains glass and the plastic tape that contains glass are bonded together.Continuously produce, the outside that strengthens waste pipe at electric smelting spigot and socket type glass forms the helical stiffening rib, and stiffening rib is distributed in 98% interval, pipe middle part, and its two ends are respectively the bellmouth and the socket of no stiffening rib.Through cooling and shaping, machine tooling is shaped on female end and the socket end, and the product after the processing carries out the demoulding through stripper.
