Abstract
The invention relates to a special-purposed attapulgite clay drying agent for glass. The drying agent is characterized in that attapulgite clay is adopted as a main raw material; the main raw material is complexed with auxiliary agents according to a certain ratio; and pelletizing and roasting activation are carried out, such that the drying agent is obtained.
Description
Technical field
The present invention relates to drier, it is attapulgite clay desiccant specified to be specifically related to a kind of glass.
Background technology
The double glazing of one piece of standard is bonded together by the glass plate of more than two or two, and form a firm seal, it is the cavity setting up a dry air or special gas between the glass more than two or two.Its structure is separated by glass plate by aluminum pipe interval box, a kind of special drying agent is injected in interval box, then sealed by the surrounding edge of a kind of elastic sealant along double glazing, because between glass plate the air closed or gas there is lower thermal conductance, so just greatly reduced by the heat of window.
The special drying agent used in double glazing, is sealed in the moisture in double glazing air layer when its function has be and adsorb to fall to produce at three: one; Two is that continuous adsorption enters the moisture in air layer in double glazing lifetime, to keep the low dew point-40 DEG C in double glazing; Three is the volatility organic solutes be sealed in when sopping up production in air layer.
When initial production double glazing, what adopt in its interlayer aluminum pipe is silica-gel desiccant, and pore is comparatively large, and only under air is in high-temperature condition, adsorbance is large, and adsorbance is very little under low humidity or hot conditions.Rear employing molecular sieve makees drier, molecular sieve have natural zeolite and artificial zeolite point, natural zeolite purity is low, and natural zeolite be become gel, crystallization under certain condition by elements such as Si, Al, Na, aging, washing generates 4A molecular sieve.The aperture of 4A is 4A °, and moisture diameter is 2.6A °, N
2molecular diameter is 3.5A °, O
2molecular diameter at 3A °, therefore 4A molecular sieve is while water molecules, also inhales N
2molecule and O
2molecule, causes in double glazing interlayer and forms vacuum, cause negative pressure, makes to scratch phenomenon in double glazing generation.For this phenomenon, people carry out cation exchange to 4A molecular sieve, KCL solution and 4A molecular sieve are reacted, with K+, Na+ is cemented out, K+ is made to be positioned on the lattice of Na+, because a K+ electronic shell more than Na+, thus ratio of ionic radii Na+ is large, fixes on lattice after a K+ displacement larger than Na+ radius, duct is diminished, become 3A by 4A, 4A is slightly less for 3A molecular sieve water demand ratio, but does not inhale N
2and O
2, from then on 3A molecular sieve is as hollow glass desiccant.
At present, the hollow glass desiccant that market is applied is 3A molecular sieve, and 3A molecular sieve hygroscopic capacity is low, and powder falling rate is high, needs to carry out ion-exchange in the solution, have blowdown, contaminated environment in washing process in production process.
Summary of the invention
The object of the invention is to:
Attapulgite clay desiccant specified for hollow glass is provided, utilizes the recessed soil characteristics of nonmetallic ore to produce Special dry agent for hollow glass, the water imbibition of this drier, mobility, compression strength, rate of wear, suction N
2, O
2the performances such as organic molecule are better than molecular sieve, and can simplify production technology, reduce costs, 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, obtains drier through pelletizing, calcination activation.Wherein, the percentage by weight of each component is: Concave-convex clay rod 50-80%, and inorganic active material 10-20%, silica gel 10-30% wherein active material are chloride.
Concrete procedure of processing is as follows: first, selects Attapulgite clay, dry abrasive dust; Secondly, adding assistant is composite in proportion; Then, pelletizing, diameter are between 0.5-4.0; Finally, 400-500 DEG C of calcination activation, packaging.
Attapulgite has another name called palygorskite or Palygorskite, be a kind of layer of chain structure containing Shuifu County's zeopan clay mineral, its crystal shape is bar-shaped, fibrous, needle-like, long 0.5-5 μm, wide 0.05-0.15 μm is 2: 1 type clay minerals, i.e. two-layer silicon-oxy tetrahedron, one deck aluminium (magnesium) oxygen octahedra structure, molecular formula is Mg

2o, its aggregate is earthy block structure, and color is greyish white, steel gray, micro-Huang or light green, greasy luster, light specific gravity, mohs hardness is 2-3 level, be viscosity and plasticity time moist, dry shrinkage factor is little, does not produce be full of cracks, water imbibition is strong, reach more than 150%, PH=8.5, because internal gutter is many, specific area is large, reaches 350m
2more than/g soil, most cation, hydrone and a certain size organic molecule all can directly by absorption inlet hole roads, and stable electrochemical property, is not easily flocculated by electrolyte.
Recessed soil has extremely strong adsorption bleaching, has the feature of adsorption selection, has catalytic, have viscosity, particularly water imbibition: can reach 24.3%, is a kind of fabulous raw material producing mineral agent.
