Description
Technical field
The present invention relates to a kind of plasticity-film bonding method, material and equipment, especially bonding for 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 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 all are that plastic plastics film forms in essence, the bonding of plastics film mainly is 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, in the engineering that environmental protection is had requirement, use tackiness agent 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 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 in normal engineering construction, be very inaccessible, 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 the construction these materials toxicity larger, workmen's healthy meeting is caused to a certain degree injury.
Summary of the invention
The bonding of plasticity-film is the organism tackiness agent that utilizes chemical process to produce in waterproof, the stoppage engineering at present, nearly all contains poisonous composition, and is difficult in the 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 base plate of Portable electromagnetic heating installation (100) is comprised of insulating base (101) and electromagnetic power power winding (102).High-power high-frequency pulsed drive electromagnetic power power 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) 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 not 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) places 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 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 plastics films, 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, 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 to 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.
