Description
Technical field
The present invention relates to a kind of method of core self demixing, particularly relate to a kind of method realizing glass fibre core self demixing.
Technical background
In recent years, energy-conserving and environment-protective become the problem that people are concerned about most, its extensive use at building field of traditional organic insulation material inflammable corrosion-prone drawbacks limit, and the shortcoming such as inorganic heat insulation material exists poor thermal insulation property, and density is large, there is significant limitation.Therefore people more and more pay attention to making and the use of heat-insulating heat-preserving material, and particularly the research of the heat-insulating property of, environment-friendlyclip clip layer material emerging to some, sound insulation value is more and more deep.
Vacuum heat-insulating plate is the one of heat insulating material; it is based on vacuum insulation principle; by improving vacuum in plate to greatest extent and filling porous low thermal conductivity material and realize thermal insulation; from its structure; be composited by the good filling core of heat-proof quality and barrier film; compound tense; first using barrier film as the coated porous filling core in protection top layer; make protection top layer by decompression vacuum pumping and fill core again to fit tightly, finally heat-sealing sealing is carried out to protection surface layer film.Vacuum heat-insulating plate has the advantages such as volume is little, lightweight, thermal conductivity factor is low, at present, domestic vacuum heat-insulating plate generally uses glass fibre as the packing material of inside, i.e. core material of vacuum heat insulation plate, but in the preparation process of present stage core, centrifugally glass-wool felt is mainly based on single-layer glass fiber.When centrifugal blast legal system is cotton, continuous print glass flows stock is introduced in the narrow meshed sedimentator of High Rotation Speed by passage by glass metal, becomes glass wool through centrifugal action with combustion flame drawing-off.Glass wool forms the unordered staggered shape glass fibre that interts in decline process, descent path is tortuous, final formed on cotton collecting machine porosity up to 70% ~ 80% single-layer glass fiber layer, in the process used, its thermal and insulating performance and sound absorption qualities all can be subject to impact to a certain extent.
Application number be 201010102777.0 patent of invention disclose a kind of manufacture method of core material of vacuum heat insulation plate, the problem that the cost that this invention exists for prior art core material of vacuum heat insulation plate is high, provide a kind of manufacture method of core material of vacuum heat insulation plate, comprise as rock wool fibers making beating online, shaping roll extrusion, vacuum dehumidified and cooling such as to be become a useful person at the step, advantage of the present invention adopts rock wool fibers, the core material of vacuum heat insulation plate produced, the performance that all needs of core material of vacuum heat insulation plate possess can be met, its production technology is simple in addition, and cost is lower.Its shortcoming is the rock wool fibers core produced is a monoblock, is unfavorable for that the price in later stage makes, has a certain impact in addition to the fire-retardant of core and sound absorption qualities.
Application number be 201210259340.7 patent of invention disclose a kind of centrifugally glass-wool and force decker online, this device is fixed on cotton collecting machine porous chain plate conveyor belt, be positioned in the middle of adjacent centrifugal head, when centrifugal blast system is cotton, the glass fibre cotton that spinning head is formed inside the conveyer belt direction of motion is layered control panel and is pressed into bottom glass fibre cotton, the glass wool that outside spinning head is formed then is pressed on bottom fiber, form the centrifugally glass-wool felt blank of layering, thickness hierarchical control plate is also provided with air flue, by air admission hole and the air outlet of upper and lower eaves both sides, can to the glass wool certain orientation descended slowly and lightly without center of gravity, a certain size wind-force, improve the utilization rate of centrifugally glass-wool.The advantage of this device is the on-line automatic layering that can realize glass wool, improves the problem that manual zoning's gained blanket of glass wool is adiabatic, sound absorption qualities is excellent not, obtains the cotton felt of centrifugal glass fibre of layering.Its shortcoming is the volume production that the method can not realize 0.3mm core, has certain limitation.
As above-mentioned two patents, the thickness of existing glass fibre core has certain limitation, part is processed after global formation, the thickness of another part is at about 1.0mm, the volume production of 0.3mm core can't be realized, therefore need a kind of method of novel core self demixing to solve existing problem.
Summary of the invention
Object of the present invention is intended to overcome the deficiencies in the prior art, provides a kind of method more efficiently, more simply realizing glass fibre core self demixing.
The technical scheme adopted for realizing object of the present invention is: a kind of method realizing glass fibre core self demixing, the device of core self demixing comprises V-shaped groove, strainer, negative pressure suction opeing, V-shaped groove adopts fiberglass to make, and it is characterized in that: described preparation method comprises the following step carried out in order:
