Description
Technical field：
The present invention relates to a kind of equipment for producing fire prevention styrofoam, more particularly to a kind of fire prevention of open type negative pressure continuous production
Styrofoam penetration equipment.
Background technology：
At present, the production technology of domestic fire-retardant heat insulation styrofoam mainly has two kinds：
1. coating method.Fire retardant and adhesive (organic gel) are added in mother metal (EOS), makes fire retardant in EPS bead tables
Face formed coating, the effect through certain pressure and adhesive and fire-retardant heat insulation polyphenyl plate blank material is made.The shortcomings that this method is
Adhesive is organic matter, inflammable, so, directly influence the fire protecting performance of warming plate.Combustion test, this insulation are done through us
The flue gas of plate is very big；Again because mother metal contains fire retardant, so, blank is not easy to use resistance wire excision forming.
2. osmosis.Fire retardant is being penetrated into manufactured styrofoam, fire retardant is formed in styrofoam honeycomb skin
Protecting film, do not need to add adhesive.The characteristics of this method is simple relative to coating method equipment, and easy to operate, product is prevented
Fiery performance is high.
But its production process majority is that under sealed conditions, the styrofoam for having fire retardant to surface smear is taken out
Vacuum, fire retardant is set to penetrate into styrofoam, shortcoming is that production process is batch (-type), low production efficiency, and the sheet material produced
Size is limited by closed chamber size, it is impossible to meets the needs of market is to different size fire-retardant heat insulation styrofoam.
Although also having by Belt Conveying styrofoam with holes, styrofoam in course of conveying by below conveyer belt with holes with
Fire-resistant fluid in tank above conveyer belt with holes is entered band by the vacuum tank of vacuum tank connection through styrofoam under vacuum
The equipment of hole belt, its shortcoming are, using Belt Conveying with holes, belt friction resistance with holes is big, high energy consumption；Belt with holes is soft
Property, during the vacuum tank that vacuum tank passes through vacuumizes, styrofoam is easily deformed, and causes product quality unstable
It is fixed；Fire-resistant fluid enters belt with holes, is attached on belt with holes, and fire-resistant fluid wastes serious, increase production cost；Easily cause band
Hole belt slippage, transfer efficiency is influenceed, reduce production efficiency；Fire-resistant fluid on belt with holes is not easily cleaned, and increases maintenance cost.
Above two equipment all has that fire retardant (fire-resistant fluid) is oversaturated to be penetrated into sheet material, stops vacuum pumping,
When taking out sheet material drying, oversaturated fire retardant (fire-resistant fluid) can separate out in sheet material, cause fire retardant (fire-resistant fluid) to waste, production
Sheet material be all saturation sheet material, product category is single.
