Description
Technical field
The present invention relates to a kind of technical field of drier, relate to the technical field of its manufacture method simultaneously.
Background technology
The drier that uses at present is lime type drier, silica type drier number in the majority, wherein lime type drier has strong basicity, severe corrosive, and the moisture absorption efflorescence and can not regeneration etc. shortcoming, make it can not be in uses such as food, medicines and health protection product, electronic instrument products, this be that people are well-known; And the silica type drier can produce alkaline waste liquor in silica gel is produced, and the silica type of contaminated environment, and production easily drier cost is also somewhat expensive, influences it and promotes the use of.The patent No. is that 92104492.5 Chinese patent " deodorant drier and manufacturing process thereof " discloses a kind of drier, it mainly is main component with the natural zeolite, its prescription is for containing zeolite 34-53%, iron hydroxide 5.3-11.9%, sodium acid carbonate 2.6-3.4%, aluminium oxide 23.7-26.3%, calcium oxide 10.5-13.6%, bentonite or clay 2.6-13.6%, this drier is because contain too much alkaline matter such as iron hydroxide, sodium acid carbonate, calcium oxide etc., make this drier present more intense alkalescence, be easy to generate corrosivity, can influence it and promote the use of, this drier is also because contain iron hydroxide, harmful material such as calcium oxide also is not suitable at food, promote the use of on the industries such as medicines and health protection product.
Summary of the invention
Primary technical problem to be solved by this invention is to provide a kind of drier at prior art, and its nonpoisonous and tasteless, contactless property burn into non-environmental-pollution is a kind of environment-friendly dry drying prescription, can repeat regeneration simultaneously and use drier with low cost.
Another technical problem to be solved by this invention provide a kind of compatibility simple, produce easily, the production method of the above-mentioned drier of production with low cost.
The present invention solves the technical scheme that above-mentioned primary technical problem adopts: this kind drier, it is characterized in that it is 10-50% that the drier main body contains calcium-base bentonite, attapulgite 90-50%, except that main body, drier also contains polyvinyl alcohol 0.2-0.6%, polyacrylamide 0.6-0.2%, calcium chloride 10-30%, above-mentioned polyvinyl alcohol, polyacrylamide and hundred parts of ratios of calcium chloride quality are to serve as to calculate benchmark with the main body gross mass, and above-mentioned hundred parts of ratios are hundred parts of ratios of quality.
Its particle equivalent diameter of above-mentioned drier is the 1-4 millimeter.
The present invention solves the technical scheme that above-mentioned another technical problem adopts: a kind of method of producing above-mentioned drier is characterized in that steps in sequence is: (1) ore dressing; Choose calcium-base bentonite and attapulgite; (2) drying and crushing; To pulverize after calcium-base bentonite and the attapulgite drying; (3) mix; Calcium-base bentonite and attapulgite are carried out compatibility according to above-mentioned ratio range, add poly-vinyl alcohol solution, polyacrylamide solution and calcium chloride solution then, make drier contain polyvinyl alcohol, polyacrylamide, the calcium chloride of said ratio scope, also contain water simultaneously, water content is to make material be fit to extruder grain to be degree; (4) extruding; In kneader, mix and push; (5) granulation; Material after the extruding is carried out granulation on comminutor; (6) drying; Drier after the granulation is carried out air dry or bake drying, finally obtain finished product.
Above-mentioned pulverizing is crushed to 100-400 order scope with calcium-base bentonite and attapulgite.
Compared with prior art, the invention has the advantages that: nonpoisonous and tasteless, the contactless property of this drier burn into non-environmental-pollution is a kind of environment-friendly dry drying prescription; Low price simultaneously can reduce the use cost of industry, and can reuse through the high temperature back of drying, and reduces use cost greatly, and it mainly adopts clay to make, and it is very extensive to originate, and is drier with low cost; Moisture pick-up properties is good, and this drier is higher than the wettability power of lime type and silica gel type drier, more is higher than pure bentonite type drier wettability power, and hydroscopicity is a kind of drier of high hygroscopic property than more than the high 50-100% of back three; This loam mould drier is because high adsorption capacity, static dehumidification are fast, go the peculiar smell ability strong, and former person's drier do not go the peculiar smell function, in the product that drier of the present invention can be widely used for not adopting oil sealing to deposit, gas phase is sealed up for safekeeping, as civilian and war products such as precision instrument, electronic product, medicines and health protection product, packagings for foodstuff, and be used for the transport by sea of container.It is simple that method of the present invention has a compatibility, produces easily and implement, and cheap for manufacturing cost, output is big, the efficient advantages of higher.
