Abstract
A composite drying agent is prepared from attapulgite and the strong water absorbent of water-soluble salt through proportional mixing, granulating, and baking or slight sinter.
Description
Technical field
The present invention relates to a kind of compound absorbent-type drier, especially a kind of have the low cost of environment protection significance, high adsorption efficiency, a widely applicable compound absorbent-type drier of clay, is specifically related to the attapulgite clay composite drying agent.
Background technology
Traditional absorbent-type drier is representative with silica gel always.But all be difficult to very over a long time decompose after silica-gel desiccant is discarded, along with the raising of environmental requirement, many countries and regions are limited day by day to the application of silica-gel desiccant.Under such market background, low production cost, the clay mineral drier that is easy to decompose, have environment-friendly function have catered to the new demand in market.But natural clay mineral is directly used as drier, and its drying efficiency is far below silica gel, so application is very restricted.
Summary of the invention
The invention provides a kind of attapulgite clay composite drying agent, not only drying efficiency is higher than silica gel, very easily decomposes after discarding, and does not influence environment, and production cost also only is higher than the natural clay mineral drier a little, only is about 1/3rd of silica-gel desiccant production cost.
Technical solution of the present invention is: attapulgite clay mixes according to a certain percentage with water miscible salt strong water absorbent, can obtain the attapulgite clay composite drying agent of indication of the present invention behind granulation, oven dry or slight sintering.
This drier Main Ingredients and Appearance comprises attapulgite clay and salt strong water absorbent, wherein water absorbing agent preferably calcium chloride (Cacl
2), magnesium sulfate (MgSO
4) or sodium sulphate (Na
2SO
4), according to requirement to indexs such as different hydroscopicity of product and drying efficiencies, the proportioning of attapulgite clay and salt strong water absorbent is generally 95 to 5 to 75 to 25, and the product attapulgite clay of specific (special) requirements and the ratio range of salt strong water absorbent can be 98 to 2 to 95 to 5 or 75 to 25 to 60 to 40.
The excellent clay of recessed soil be a kind of be the clay pit of diagnostic mineral with the sepiolite group, wherein the content of attapulgite mineral is more than 20%; Sepiolite, montmorillonite and other common symbiosis, the associated mineral that can contain different proportion in the attapulgite clay; The clay mineral total amount that comprises sepiolite, montmorillonite is more than 60%; The content of attapulgite and sepiolite is equivalent replacement fully.
The present invention utilizes the abundant formed fabulous water storage of mineral internal void of the stronger water absorbing properties of salt strong water absorbent and attapulgite clay, and it is not moistening to make that " attapulgite clay composite drying agent " of the present invention reaches the deadweight 50% agent surface that still can keep dry when above in moisture absorption.With grade higher attapulgite clay and magnesium sulfate (MgSO
4) or sodium sulphate (Na
2SO
4) compound and product that obtain through slight sintering not only has good water absorbing properties, and have good physics and a chemical inertness, in most liquid, can keep not taking place chemical reaction and self not produce distortion, be specially adapted to the dehydration of organic liquid phase such as lipid, ketone and some sensitive materials solution, can the substituted molecule sieve in the dehydration purifying technique that many chemical products are produced or activated alumina use as dehydration purifier, have the significant advantage of dewatering efficiency height, low production cost.
The technology of the present invention is reasonable, and technology is simple, China's attapulgite clay rich in mineral resources, and the production cost is lower, and compliance with environmental protection requirements is widely applicable, has inexpensive clear superiority, helps general promotion and application.
The specific embodiment
Embodiment 1: " the attapulgite clay composite drying agent " of present embodiment is primary raw material with the attapulgite clay, and the raw ore crushed after being dried to by 60 mesh sieves, is added 15% calcium chloride (Cacl
