Description
Technical field
A kind of method and heater thereof of repairing the rubber conveyer belt breakage of the present invention belongs to conveyer belt recovery technique field.
Background technology
The conveyer belt breakage is the problem that the conveyer belt user is difficult to avoid, and also is the problem that influences the conveyer belt safe operation, and for a long time, people are constantly exploring and more effectively keeping in repair solution, and the means that solve this class problem at present both at home and abroad mainly contain three kinds:
First kind is: the elevated temperature heat sulfuration is repaired.This technology is to adopt the principle of the vulcanization of rubber, and conveyer belt is heated to 145-155 degree centigrade, and the base rubber at damaged position and the new rubber of filling are merged under certain pressure, finishes reparation.This method can be recovered the original performance at damaged position substantially, but device therefor is heavy, the operating time is long, speed is slow, efficiency is low, is not suitable for the quick repairing of big workload.
Second kind is: cold-adhered rubber is repaired the bar reparation.This technology derives from abroad, the similar sticking process of mending a puncture of principle, i.e. and polishing-brush coating-fit-roll at surperficial bonding or the double-deck rubber repairing of a slice bar of rubber conveyer belt, makes damaged position restore funcitons.This method is easy to use, can solve problem such as tear fast, but the wearability of rubber repairing bar is not high, service life after the repairing is short, be not suitable for the serious edge repair of impact wear, limitation is big during application, and the method is subjected to low temperature limitation, need to be heating and curing and to use below 10 degree, can construct hardly below 5 degree.
The third is: the rubber healant is repaired.This technology is that the polymer with the dual-component polyurethane class is filled in breakage, waits and solidifies the elastomer that certain serviceability is realized having in the back.This method can in time be repaired little defective, but uses limitedly, only limit to some undersized urgent repairings, and combination property is poor.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, and technical problem to be solved provides a kind of restriction that is not subjected to environment temperature, only needs the method and the heater thereof of low-temperature heat and easy to operate reparation rubber conveyer belt breakage.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of method of repairing the rubber conveyer belt breakage, carry out according to following steps:
A, polishing: earlier with in the 5-20 cm range around the conveyer belt breakage with the polishing of angle grinding machine clean and roughening, the bonding plane that will repair bar again is with the clean roughening also of angle grinding machine polishing;
B, conveyor belt surface chemical treatment: adopt rubber finishing agent to handle, rubber finishing agent brushing is uniformly dried on the conveyor belt surface of polishing;
C, brush coating: adhesive is brushed uniformly on conveyer belt and repairing bar surface treated;
D, heat activation cementability: the position with conveyer belt and repairing bar have been smeared adhesive, be heated to 50 ℃-120 ℃ with heater, kept 2-5 minute;
E, applying: under hot state, promptly temperature will be repaired the bar bonding plane rapidly and be attached on the surface of conveyer belt breakage more than 50 ℃ the time;
F, roll: under hot state, promptly temperature applies rolling pressure for the position that posts more than 50 ℃ the time, rolls the width degree greater than repairing 50% of bar width, and the pressure size controls to does not have the folder dead level;
G, hammering: impact repairing bar 1-2 minute with hand-held rubber hammer, impact area greater than repairing 120% of bar area;
The material of described repairing bar is a thermoplastic polyurethane.
The cross section of described repairing bar or be trapezoidal, or be square, or be L shaped.
Implement a kind of heater of repairing the method for rubber conveyer belt breakage; comprise shell, heater, reflector, catch net, aluminium angle steel and switch; reflector and shell are " ∩ " shape; reflector is positioned at the inside of shell; top in the reflector is equipped with heater, and two aluminium angle steel symmetries are installed in the below of shell and reflector, and catch net is installed in the below of aluminium angle steel; one end of shell side is the control zone, is provided with switch in the control zone.
Heater, reflector, catch net and aluminium angle steel be symmetric arrangement up and down, becomes double-decker, and shell is a plate object, is arranged in the both sides of reflector.
Also be provided with temperature controller, contactor and thermocouple in the control zone.
The beneficial effect that the present invention is compared with prior art had is:
1, repairing the bar reparation with cold-adhered rubber and compare, is heat bonding because the present invention adopts, thus be not subjected to the restriction of environment temperature substantially, also need not hardening time after the reparation, can use at once.
2, compare with elevated temperature heat sulfuration reparation, heating-up temperature of the present invention is low, and temperature controlling range is big, and between 50 ℃-120 ℃, it is easier to control, more convenient operation.
3, among the present invention used repairing strip adoption the thermoplastic polyurethane material, repair bar with rubber and compare, had stronger wearability, stretching resistance, obdurability and ageing-resistant characteristic, and an environmental protection.
4, have in the used repairing bar among the present invention and be exclusively used in that the square of repairing edge breakage is repaired bar and the L type is repaired bar, filled up the blank that edge breakage is in the past repaired.
