Description

Plug-connected type pipe spontaneous heating adhesive material

Technical field

The present invention relates to a kind of plug-connected type pipe spontaneous heating adhesive material, belong to electromagnetic technology field, especially bonding at the fusion of the plastic tube in the production that environmental requirement is arranged, the construction of domestic water engineering plastics pipe.

Background technique

It is the importance that water resources is utilized that agricultural irrigation, people hold drinking water, and along with fast development of national economy, the imbalance between supply and demand of water resources is serious day by day, has seriously restricted development and national economy, and using water wisely has risen to state basic policy, becomes the whole people's common recognition.

Between water head site and the user almost without exception the user that the water of water head site need be flowed to use, the conveying of water resources is mainly undertaken by the form of channel and pipeline.The water conservancy of channel hydraulic pipeline generally about 0.5, that is to say that nearly 50% water is not utilized and slatterned by crops, and the water conservancy of pipeline water delivery can reach more than 0.95, and the irrigation water utilization ratio is improved greatly with coefficient with coefficient for irrigating.

Utilize pipeline that water is transported to the user, can reduce seepage and the evaporation loss of water in the open channel course of conveying, can also avoid polluting, particularly important to domestic water.

Aqueduct generally adopts steel pipe, concrete pipe, plastic tube etc., and along with the fast development of petrochemical industry, the application of plastic tube is increasingly extensive, has become the main tubing of hydraulic engineering pipeline water delivery at present.

The construction of plastic tube mainly is to adopt chemical glue to carry out bonding method, adhesive is the chemical product of being made by the number of chemical raw material, certain toxicity is nearly all arranged, in the engineering that environmental protection is had requirement, use adhesive to carry out bonding construction quality being had negative effect, relate in particular to people's aspect, domestic water field.

On the other hand, aspect bonding quality, quality and consumption to adhesive are had relatively high expectations, when the tensile strength of plastic tube equates with the bonding tensile strength of joint part, can reach the optimum balance of quality and cost, but in normal engineering construction, be difficult to reach, in order to guarantee whole construction quality, tend to cause the waste of material.

Again on the one hand, stick with glue the bonding method of agent the environmental requirement of constructing is also had certain requirement, use normal under some adhesive normal temperature, the words that temperature is low just need special processing, some adhesive must heat and could use, and in the construction these materials toxicity bigger, workmen's healthy meeting is caused to a certain degree injury.

Summary of the invention

The bonding of plastic tube is the organic substance adhesive that utilizes chemical method to produce in the water delivery engineering construction at present, nearly all contains poisonous composition, and is difficult in the construction grasping best adhesive use amount, the waste that causes quality problems easily or produce adhesive; Secondly weather environment also can affect greatly construction; More important question is that can pollute environment, especially can workmen's physical and mental health be caused damage.

The present invention adopts following technological scheme:

Comprise electromagnetism heating tape (101) two-part content that magnetic conductive material net (203) and portable electromagnetic heater drive.

Magnetic conductive material net (203) is to adopt environmental protection, nontoxic magnetic conductive metal material to make, the fusion that is used for plastic tube is bonding, and it is bonding that multi-form magnetic conductive material net (203) can be used for the fusion of the plastic tube of plug-in type and dock and plastic plate.

Magnetic conductive material net (203) places the centre of flared tube (201) and straight cutting pipe (202), magnetic conductive material net (203) absorbs electromagnetism heating power generation eddy current and generates heat, its heat can make the surface of contact partial melting of the flared tube (201) that is in contact with it and straight cutting pipe (202) and fuse and bond together, and realizes the bonding of plastic tube.

Bonding can repeatedly the repeating of plastic tube fusion, butt joint can't harm reparation, with convenient construction.

Portable electromagnetic heater is used for producing the high-frequency impulse electromagnetic power, manufacture and design with reference to working principle of induction cooker, comprise power circuit, the high-power high-frequency pulse conversion circuit, the infrared measurement of temperature circuit, automatic control circuit, parts such as device housings, the controlled high-frequency impulse electromagnetic power of this circuitry output drives electromagnetism heating tape (101), send the high-frequency impulse electromagnetic power, act on the magnetic conductive material net (203) that the magnetic conductive metal material is made, make it obtain required electromagnetic power and generate heat.

Utilize the temperature of infrared measurement of temperature circuit probe detection magnetic conductive material net (203), automatic control circuit is according to this real time temperature collection value, the output of control high-frequency impulse electromagnetic power makes magnetic conductive material net (203) reach specified operating temperature, to guarantee bonding quality.

The present invention compares with the technology that adopts adhesive bonding plastics pipe has tangible cost advantage, especially the magnetic conductive material net that adopts environmental protection, nontoxic magnetic conductive material to make, material source or production technology all are relatively easy to, be applied in people produce, in the water delivery engineering of production that life is closely bound up, domestic water, the economic and social benefit of its generation can't be estimated.
