Abstract
A process for further processing of high-viscosity adhesive uses attapulgite clay ore as material and includes such steps as separation, crushing, immersing in activating agent, grinding, baking, crushing, high-speed stirring and measuring viscosity by rotary viscometer. It features simple process, rich raw material and low cost. Said adhesive can be used to prepare molecular sieve that has high breaking strength and long service life.
Description
The present invention relates to a kind of binding agent complete processing, exactly is a kind of technique for producing high-viscosity adhesive ' Aotu ' soil.
Molecular sieve is widely used in petroleum refining, the chemical industry and makes catalyzer, does the air filtration agent in the electrical and machinery industry, makes pharmaceutical carrier etc. in medicine, the agricultural chemicals.Binding agent is the main component of producing molecular sieve, and what produce the molecular sieve employing at present is that positive dry ground is made binding agent, thereby resisting breakage intensity is low, and work-ing life is short.
The objective of the invention is fully to develop the use value in attapulgite clay ore deposit,, be used to produce high strength for people provide a kind of performance good high stick, anti-broken, the molecular sieve of long service life.
The objective of the invention is to realize by following technical scheme.
The present invention is to be raw material with the attapulgite clay ore deposit, and the ore after impurity is removed in ore dressing is carried out fragmentation, adds 0.5～10% magnesium oxide or magnesium hydroxide activator, puts into water and soaks 1～2 day; Ore after soaking being rolled, promptly refine mud, press filtration, enter and send rotational viscosimeter to after stirring in the homogenizer and detect, is 3000～3500CPS when recording viscosity, and water content is to dry in 50～80% o'clock; Again it is sent to and send into rotational viscosimeter after stirring in the homogenizer and detect, when viscosity is 2800～3500CPS, after water content reduces to 10～20% it is ground into Powdered, sending rotational viscosimeter again after homogenizer stirs to detects, recording viscosity is 2500～3500CPS, fineness of powder is 150～300 orders, and water content≤15% o'clock can be sold through metering packing.
Advantage of the present invention is to be raw material with the attapulgite clay ore deposit, adding activator through fragmentation soaks, make the abundant activation treatment of attapulgite clay, its viscosity, suspension and other performance are improved, adopt homogenizer stirring and rotational viscosimeter to cooperate the detection of carrying out viscosity to control again, make it produce full-bodied binding agent.
Another advantage of the present invention is that technology is simple, and abundant raw material is with low cost.
By the following examples, the present invention is done to describe further.
Embodiment 1:
Ore after impurity is removed in ore dressing is carried out fragmentation, add 0.5% magnesium oxide, put into water and soaked 1 day; Ore after soaking is rolled, enter and send the rotational viscosimeter detection after homogenizer stirs to, recording viscosity is 3000～3500CPS, water content is to dry in 50～80% o'clock, sending into rotational viscosimeter after stirring in homogenizer detects again, recording viscosity is 2800～3500CPS, after water content reduces to 10～20% it is ground into Powdered, sending rotational viscosimeter again after homogenizer stirs to detects, recording viscosity is 2500～3500CPS, fineness of powder is 150～300 orders, and water content≤15% o'clock can be sold through metering packing.
Embodiment 2;
Ore after impurity is removed in ore dressing is carried out fragmentation, add 10% magnesium oxide, put into water and soaked 1 day, other is with embodiment 1.
