Description
Technical Field
The invention relates to the technical field of processing of isolation plates, in particular to a processing technology of a gas isolation plate.
Background
The gas-proof and water-proof isolation technology for tunnel engineering in China generally adopts hard plastic plates, and through years of practice, the material is greatly changed by high and low temperatures, the firm close adhesion of the material cannot be ensured in cold and hot joint construction, and in addition, the transportation construction is troublesome due to the fact that the material cannot be folded and rolled, and the material is inconvenient.
In order to solve the problems, the utility model with the Chinese patent application number of 99214605.4 discloses a rubberized rubber gas isolation board for a tunnel, which consists of a base layer and a surface layer, wherein the base layer is full glass fiber cloth, and the surface layer is an acid-base-resistant and anti-aging rubber mixture which is pressed on the full glass fiber cloth at high temperature and high pressure; during manufacturing, the rubber mixture is placed on the glass fiber cloth, the rubber mixture and the glass fiber cloth are placed in a pressing box together, and the gas isolation plate is obtained after pressing for 2-3 hours.
Above scheme is through replacing into soft rubber and glass fiber cloth with the plastics panel of stereoplasm, has solved not enough among the prior art, but above scheme still has following problem, and glass fiber cloth is the coating gluing agent, and at the in-process of pressurize, also not in time carry out the repressing box and mend the pressure, when pressing rubber mixture to glass fiber cloth, rubber mixture and glass fiber cloth laminating quality are general, and easy fracture, and the gas division board life that the inferior method was made is lower.
Disclosure of Invention
The invention aims to provide a processing technology of a gas isolation plate, which can improve the bonding quality of a rubber mixture and glass fiber cloth and can prolong the service life of the isolation plate.
The processing technology of the gas isolation plate in the scheme comprises the following steps:
A. dust removal: putting the glass fiber cloth on a conveyor, intermittently moving the conveyor, intermittently blowing the glass fiber cloth by using an inflator, and further dedusting the glass fiber cloth by using an electrostatic dedusting cylinder in a rotating manner;
B. gluing: coating a water-insoluble adhesive on the glass fiber cloth by using a glue spreader, wherein the rotating speed of a roller is 5-7 m/min;
C. drying: communicating and rotating the electrostatic dust removal cylinder and the drying cylinder, and drying the glass fiber cloth after gluing by using the drying cylinder while removing dust from the glass fiber cloth;
D. pressing: placing a rubber plate on glass fiber cloth, placing the rubber plate and the glass fiber cloth into a pressing box together, driving an inflator to ventilate and pressurize the pressing box through a cam linked with an electrostatic dust collection cylinder, and stopping ventilation when the pressure in the pressing box reaches 22-24 Mpa; maintaining the pressure for 2-3h, and ventilating and supplementing the pressure once every 0.5h during the pressure maintaining period.
The working principle of the scheme is as follows: A. dust removal: putting the glass fiber cloth on a conveyor, intermittently moving the conveyor, intermittently blowing the glass fiber cloth by using an inflator, and further dedusting the glass fiber cloth by using an electrostatic dedusting cylinder in a rotating manner; conveyer and inflater cooperation ground all sweep the everywhere of glass fiber cloth for glass fiber cloth is swept cleaner, and every intermittent type pauses, also makes the electrostatic precipitator section of thick bamboo can remove tiny dust on the glass fiber cloth more fully, guarantees that glass fiber cloth surface is clean.
B. Gluing: coating a water-insoluble adhesive on the glass fiber cloth by using a glue spreader, wherein the rotating speed of a roller is 5-7 m/min; and gluing the clean surface of the glass fiber cloth to prepare for subsequent pressing.
C. Drying: communicating and rotating the electrostatic dust removal cylinder and the drying cylinder, and drying the glass fiber cloth after gluing by using the drying cylinder while removing dust from the glass fiber cloth; the glued glass fiber cloth is dried, the solvent in the water-insoluble adhesive is removed completely, and gaps are prevented from being formed at the pressing positions of the glass fiber cloth and the rubber plate due to the existence of the solvent, so that the glass fiber cloth is better attached to the rubber plate.
D. Pressing: placing a rubber plate on glass fiber cloth, placing the rubber plate and the glass fiber cloth into a pressing box together, driving an inflator to ventilate and pressurize the pressing box through a cam linked with an electrostatic dust collection cylinder, and stopping ventilation when the pressure in the pressing box reaches 22-24 Mpa; maintaining the pressure for 2-3h, and ventilating and supplementing the pressure once every 0.5h during the pressure maintaining period. Through on pressing the glass fiber cloth after the rubberizing with the rubber slab to regularly carry out the repressing box and mend the pressure, can make the pressting box internal gas pressure maintain in suitable within range longer, thereby can make the rubber slab suppress the glass fiber cloth better on, the effect of rubber slab and glass fiber cloth laminating is better.
Compared with the prior art, the beneficial effect of this scheme does: this scheme is through carrying out the rubberizing to glass fiber cloth to on pressing the glass fiber cloth after the rubberizing with the rubber slab, cooperate the operation that the suppression case was regularly mended to press again, make the rubber slab can suppress the glass fiber cloth better on, the quality of rubber slab and glass fiber cloth laminating is better, is difficult for the fracture, thereby has prolonged the life of gas division board.
Further, in the step A, the glass fiber cloth is blown by using an air box uniformly distributed with nozzles. The arrangement of the nozzle can pressurize the sprayed gas, and the pressurized gas can enable the surface of the glass fiber cloth to be swept more cleanly.
And further, gluing the glass fiber cloth by using at least two glue coating rollers which are arranged in sequence in the step B. Through the setting of a plurality of glue spreader for a plurality of glue spreader all can carry out the rubber coating to glass fiber cloth, guarantee that glass fiber cloth rubber coating is more abundant.
Further, the water-insoluble adhesive in the step B is an organic silicon resin adhesive. The gas division board made has better waterproof effect.
And further, in the step C, the static and dynamic electrostatic dust collection cylinder and the drying cylinder are driven to rotate together by the motor. The glass fiber cloth after being glued can be dried while the dust is removed, and compared with the operation of drying after the glass fiber cloth is completely removed and glued, the operation improves the manufacturing efficiency.
Further, the steps C1, C1 and collection are also included between the step C and the step D: and collecting the dried glass fiber cloth by using a collecting box. Storing the prepared glass fiber cloth for later use, and preparing for pressing operation; in the pressure maintaining process of the pressing box, glass fiber cloth meeting the requirement can be manufactured, after the pressing box finishes pressing, the manufactured gas isolation plate needs to be taken out of the pressing box, and an operator can timely supplement the standby glass fiber cloth into the pressing box, so that the pressing box can carry out continuous production.
