Description
Technical field
The present invention relates to the bonding spontaneous heating material net of a kind of plastic sheeting, belong to electromagnetic technology field, especially bonding at the fusion of the moldable film in the waterproof that environmental requirement is arranged, the stoppage engineering construction.
Background technology
Water resources problems is well-known, and using water wisely 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, are the retaining and the water delivery loss that reduce water resource, and seepage control project is absolutely necessary.
Some need the facility of impervious leakage-stopping housing basement, methane-generating pit, pollutant antiseepage pond etc., and the agricultural production facilities such as pattern plastic warmhouse booth that developed rapidly in recent years, and they equally also exist the bonding problem of plastic sheeting.
The geotextiles that the hydraulic engineering antiseepage is adopted, the plastic sheeting of daily production, living needs etc., they all are that plastic plastic sheeting is formed in essence, the bonding of plastic sheeting mainly is to adopt adhesive to carry out bonding method at present, adhesive is the chemical products 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 sphere of life aspect.
On the other hand, aspect bonding quality, quality and consumption to adhesive are had relatively high expectations, when the tensile strength of plastic sheeting equates with the bonding tensile strength of blank area, 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 specially treated, some adhesive must heat 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 plasticity film is the organic matter adhesive that utilizes chemical method to produce in waterproof, the stoppage engineering 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 technical scheme:
Scheme comprises two parts content: material magnetic conductive material net (020) and portable electromagnetic heating apparatus that the plasticity film is bonding.
Magnetic conductive material net (020) is made up of the less magnetic conductive metal material of resistivity, is to use as a kind of adhesives of plasticity film.
Portable electromagnetic heating apparatus is used for to magnetic conductive material net (020) conveying capacity, its Circuits System can become the transformation of electrical energy that multiple power supplys such as civil power, accumulator jar provide the high-power high-frequency pulse, drives electromagnetic power output winding (102) output high-frequency impulse electromagnetic power.
The base plate of portable electromagnetic heating apparatus (100) is made up of insulating base (101) and electromagnetic power output winding (102).High-power high-frequency pulsed drive electromagnetic power output winding (102) sends by insulating base (101), load and circuit part is thoroughly isolated, to guarantee Electrical Safety.
The high-frequency impulse electromagnetic power runs into magnetic conductive material, especially the magnetic conductive material net (020) made of the less magnetic conductive metal material of resistivity, will make it obtain the high-frequency impulse electromagnetic power and produce eddy current, become the load of electromagnetic power output winding (102); If do not have the magnetic conductive metal material within the specific limits, portable electromagnetic heating apparatus just is in Light Condition.
Magnetic conductive material net (020) places the centre of following film lap joint (031) of last film lap joint (011) and following film (030) of the last film (010) of plasticity film, move operation is gone up in the film lap joint (011) on the plasticity film of portable electromagnetic heating apparatus, 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 last film lap joint (011) that is in contact with it and the contact-making surface generating unit fractional melting of following film lap joint (031), and then it is bonding to finish the fusion of plasticity film.
Because the heat that magnetic conductive material net (020) produces is limited in the centre of two blocks of plastic sheetings, outwards distribute slowly, it is bonding that energy seldom just can be finished the fusion of plasticity film, energy-conservationly makes things convenient for 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, makes magnetic conductive material net (020) reach specified operating temperature.
Magnetic conductive material net (020) also needs to have certain intensity, and characteristic and the thickness of film (030) were relevant under its thickness wiry last film (010) big or small with mesh and need be bonding reached.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 to be repeated, and the butt joint position can't harm reparation, with convenient construction.
Can carry out bonding planar non-magnetic organic matter material by the method for fusion, with identical method, it is bonding to utilize magnetic conductive material net (020) also can fuse it.
The present invention compares with the technology that adopts the bonding plasticity film of adhesive 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 retaining of water resource that life is closely bound up, water delivery process, the economic and social benefit of its generation can't be estimated.
