Abstract
The invention unfurls the stone soil dry dose only used for the hollow glass. Get the stone soil as the main material; add other dose, heat, rounding to make it. Percentage by weight: stone soil50--80%, inorganic active material10--20%, gum10--30%: and the active material is chloride. The producing steps: first, choose stone soil dry dose, dry and crash powders; next, add other dose by percentage; then, round, diameter is between 0.5--4.0mm; last, heat at 400--500 degC, pack them. The craft of the invention is simple, costs little, and attaches water well, so it's a new dry dose for the hollow glass.
Description
Affiliated technical field
The present invention relates to drier, it is attapulgite clay desiccant specified to be specifically related to double glazing.
Background technology
The double glazing of a standard is to be bonded together by the glass plate more than two or two, forms a firm seal, and it is a cavity of setting up a dry air or special gas between the glass more than two or two.Its structure is by the aluminum pipe interval box glass plate to be separated, inject a kind of special drying agent in the interval box, with the surrounding portion of a kind of elastic sealant it is sealed then along double glazing, because air that is sealed between the glass plate or gas have lower thermal conductance, so just reduced widely by the heat of window.
The special drying agent that uses in the double glazing, its function has three: one, and absorption is sealed in the moisture in the double glazing air layer when falling to produce; The 2nd, continuous adsorption enters the moisture in the air layer in the double glazing lifetime, to keep the low dew point-40 ℃ in the double glazing; The 3rd, sop up the volatility organic solute that is sealed in when producing in the air layer.
When the initial production double glazing, what adopt in its interlayer aluminum pipe is silica-gel desiccant, and the silica gel aperture is bigger, only is under the high-temperature condition at air, and adsorbance is big, and adsorbance is very little under low humidity or hot conditions.The back adopts molecular sieve to make drier, and molecular sieve has the branch of natural zeolite and artificial zeolite, and natural zeolite purity is low, and natural zeolite is to become gel, crystallization, aging, washing generation 4A molecular sieve under certain condition by elements such as Si, Al, Na.The aperture of 4A is 4A °, and the moisture diameter is 2.6A °, N
2Molecular diameter is 3.5A °, O
2Molecular diameter at 3A °, so the 4A molecular sieve the suction molecule in, also inhale N
2Molecule and O
2Molecule causes in the double glazing interlayer to form vacuum, causes negative pressure, makes in the double glazing generation and scratches phenomenon.At this phenomenon, people carry out cation exchange to the 4A molecular sieve, KCL solution and the reaction of 4A molecular sieve, with K+ Na+ are cemented out, K+ is positioned on the lattice of Na+, because K+ is Duoed an electronic shell than Na+, thereby ratio of ionic radii Na+ is big, one than fixing on lattice after the big K+ displacement of Na+ radius, the duct is diminished, become 3A by 4A, 4A is less slightly for 3A molecular sieve water demand ratio, but does not inhale N
2And O
2, from then on the 3A molecular sieve is as hollow glass desiccant.
At present, the hollow glass desiccant of using on the market is the 3A molecular sieve, and 3A molecular sieve hygroscopic capacity is low, and the powder rate that falls height needs in the production process to carry out ion-exchange in solution, blowdown is arranged, contaminated environment in the washing process.
Summary of the invention
The objective of the invention is to: provide double glazing attapulgite clay desiccant specified, utilize the recessed soil characteristics of nonmetallic ore to produce double glazing special drying agent, the water imbibition of this drier, flowability, compression strength, rate of wear, suction N
2, O
2Performances such as organic molecule are better than molecular sieve, and can simplify production technology, reduce cost, and improve recessed native added value.
Technical solution of the present invention is: getting Concave-convex clay rod is primary raw material, adds additive compound in proportion, and process is made ball, calcination activation makes drier.Wherein, the percentage by weight of each component is: Concave-convex clay rod 50-80%, inorganic active material 10-20%, silica gel 10-30% wherein active material are chloride.
Concrete procedure of processing is as follows: at first, select the Concave-convex clay rod ore deposit, dry abrasive dust; Secondly, adding assistant is composite in proportion; Then, make ball, diameter between 0.5-4.0; At last, 400-500 ℃ of calcination activation, packing.
Attapulgite has another name called palygorskite or Palygorskite, be a kind of layer of chain structure contain Shuifu County's zeopan clay mineral, its crystal shape is bar-shaped, fibrous, needle-like, long 0.5-5 μ m, wide 0.05-0.15 μ m is 2: 1 type clay minerals, promptly two-layer silicon-oxy tetrahedron, layer of aluminum (magnesium) oxygen octahedra structure, molecular formula is Mg

2O, its aggregate are the earthy block structure, and color is greyish white, steel gray, a little Huang or light green, greasy luster, light specific gravity, mohs hardness are the 2-3 level, be viscosity and plasticity when moist, it is little to do shrinkage factor, does not produce be full of cracks, water imbibition is strong, reach more than 150%, PH=8.5 is because inner duct is many, specific area is big, reaches 350m
2More than/g the soil, most cation, hydrone and a certain size organic molecule all can directly be adsorbed in the duct, and stable electrochemical property is difficult for being flocculated by electrolyte.
Recessed soil has extremely strong adsorption bleaching, and the feature of the absorption selected is arranged, and catalytic is arranged, and viscosity is arranged, particularly water imbibition: can reach 24.3%, be a kind of fabulous raw material of producing mineral agent.
The specific embodiment
Example 1: produce the double glazing special drying agent according to following steps: at first, select recessed Tu Kuang, dry abrasive dust 200 orders; Secondly, composite with 50% recessed soil, 20% chloride, 30% silica gel; Then, make ball, diameter 0.5mm; At last, 400 ℃ of calcination activations get finished product, packing.
