Abstract
The invention discloses a fusing splice method of plastic thin films. The fusing splice method of the plastic thin films comprises high-frequency pulse electromagnetism power transmitting equipment and a magnetic-conductivity material net, wherein the magnetic-conductivity material net (020) works only under cooperation of the high-frequency pulse electromagnetism power transmitting equipment, the magnetic-conductivity material net (020) is arranged between an upper film lap joint (011) of an upper film (010) and a lower film lap joint (031) of a lower film (030), wherein the upper film lap joint (011) of the upper film (010) and the lower film lap joint (031) of the lower film (030) need to be spliced. The high-frequency pulse electromagnetism power transmitting equipment is arranged outside of the upper film lap joint (011). High-frequency electromagnetic pulse which is transmitted by the high-frequency pulse electromagnetism power transmitting equipment is exerted on the magnetic-conductivity material net (020). The magnetic-conductivity material net (020) absorbs high-frequency pulse electromagnetism power to emit heat to enable contact surfaces of the plastically thin films which contact with the magnetic-conductivity material net (020) to partially melt and fuse to be spliced. The magnetic-conductivity material net (020) can be used for being heated for many times to overcome the splicing splice defects of the plastic thin films.
Description
Technical field
The present invention relates to a kind of fusion adhering method of plasticity-film, belong to the electromagnetism metal field, especially bonding for the fusion of the moldable film in the waterproof that environmental requirement is arranged, stoppage engineering construction.
Background technology
Water resources problems is well-known, and water saving has become our state basic policy.In order to increase income and decrease expenditure, people have built a large amount of retainings, diversion, water lift engineering, and for reducing retaining and the water conveyance loss of water resources, seepage control project is absolutely necessary.
Some need the facility of impervious leakage-stopping housing basement, methane-generating pit, pollutent antiseepage pond etc., and the agriculture production facilities such as pattern plastic warmhouse booth that developed rapidly in recent years, and they equally also exist the bonding problem of plastics film.
The geotextile that the hydro project antiseepage is adopted, the plastics film of daily production, living needs etc., they are all that plastic plastics film forms in essence, the bonding of plastics film is mainly to adopt tackiness agent to carry out bonding method at present, tackiness agent is the Chemicals of being made by the number of chemical raw material, certain toxicity is nearly all arranged, use tackiness agent to carry out bonding construction quality being had negative effect in the engineering that environmental protection is had requirement, relate in particular to people's sphere of life aspect.
On the other hand, aspect bonding quality, quality and consumption to tackiness agent are had relatively high expectations, when the tensile strength of plastics film equates with the shank adhesion strength, can reach the optimum balance of quality and cost, but be very inaccessible in normal engineering construction, 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 tackiness agent normal temperature, the words that temperature is low just need special processing, some tackiness agent must heat use, and in construction these materials toxicity larger, workmen's healthy meeting is caused to a certain degree injury.
Summary of the invention
In waterproof, stoppage engineering, the bonding of plasticity-film is the organism tackiness agent that utilizes chemical process to produce at present, nearly all contains poisonous composition, and is difficult in construction grasping best tackiness agent usage quantity, the waste that easily causes quality problems or produce tackiness agent; 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 technical scheme:
Scheme comprises two portions content: material magnetic conductive material net (020) and Portable electromagnetic heating installation that the plasticity-film is bonding.
Magnetic conductive material net (020) is comprised of the less magnetic conductive metal material of resistivity, is to use as a kind of adhesives of plasticity-film.
The Portable electromagnetic heating installation is used for to magnetic conductive material net (020) conveying capacity, its Circuits System can become the transformation of electrical energy that the multiple power sources such as civil power, accumulator jar provide the high-power high-frequency pulse, drives electromagnetic power power winding (102) output high-frequency impulse electromagnetic power.

The high-frequency impulse electromagnetic power runs into magnetic conductive material, especially the magnetic conductive material net (020) that the magnetic conductive metal material that resistivity is less is made, will make it obtain the high-frequency impulse electromagnetic power and produce eddy current, become the load of electromagnetic power power winding (102); If there is no within the specific limits the magnetic conductive metal material, the Portable electromagnetic heating installation just is in no cargo conditions.
magnetic conductive material net (020) is placed in the centre of lower film lapping (031) of upper film lapping (011) and lower film (030) of the upper film (010) of plasticity-film, the Portable electromagnetic heating installation is at the upper move operation of the upper film lapping (011) of plasticity-film, the high-frequency impulse electromagnetic power of its transmission passes through the plasticity-membrane action of overlap in magnetic conductive material net (020), make magnetic conductive material net (020) produce eddy current and generate heat, the heat that produces can make the upper film lapping (011) that is in contact with it and the contact surface generating portion of lower film lapping (031) melt, and then the fusion of completing the plasticity-film is bonding.
The heat that produces due to magnetic conductive material net (020) is limited in the centre of two blocks of plastics films, outwards distributes slowly, and it is bonding that energy seldom just can be completed the fusion of plasticity-film, energy-conservationly facilitates again.
Also need to be equipment configuration infrared measurement of temperature circuit probe, survey the temperature of magnetic conductive material net (020), the automatic control circuit of equipment is adjusted the high-frequency impulse electromagnetic power of transmission automatically according to this temperature, make magnetic conductive material net (020) reach specified working temperature.
Magnetic conductive material net (020) needs that also certain intensity is arranged, and its thickness wiry is relevant with the characteristic and the thickness that need bonding upper film (010) and lower film (030) with the mesh size.Suitable wire diameter and mesh size can make the fusion adhesive effect of plasticity-film better.
The fusion of plasticity-film of the present invention is bonding can repeatedly be repeated, and the butt junction position can't harm reparation, with convenient construction.
Can carry out bonding planar non-magnetic organism material by the method for fusion, with identical method, utilize magnetic conductive material net (020) also can fuse it bonding.
The present invention compares with the technology that adopts the bonding plasticity-film of tackiness agent has obvious 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 retaining of water resources that life is closely bound up, water delivery process, the economic and social benefit of its generation can't be estimated.
