Description
One, affiliated technical field
The present invention relates to a kind of mixed equipment that reaches surface modification of micro nano powder that is used for.Be mainly used in even continuous the mixing of several kinds of micro nano powders, carry out particle surface activation, modification processing simultaneously, thereby preparation micro-nano composite granule also can be used for certain micro nano powder is carried out surface modification.Be a kind of dry process equipment of micro nano powder.
Two, background technology
The existing powder surface modification equipment of China is borrowed from chemical machinery mostly, thereby can not be accomplished the modification task well.The main modified device that uses is: gravity blender, pneumatic blender, rotary drum mixer, V-Mixer, Z type mixer, high-speed mixer and high-speed mixer and cooling and mixing unit (being called for short the high cold unit that stirs), mill, banbury, mixed milling type single screw extrusion machine, this mixing roll of cloth, double screw extruder and static mixer, cavity blender and stretching blender etc.
The subject matter that these equipment exist is:
1. majority is step, and continuous equipment such as single, double screw extruder mostly are linear motion types, and mixed effect is poor.Existence yields poorly, and energy consumption is big, and labor strength is high, is prone to cause problems such as environmental pollution.
2. it is slow to heat up, and modification time is long, and opposite modifier consumption is big, and modified effect is poor.
3. comparatively speaking, highly coldly stir that the unit price is low, durable, easy to operate, modified effect is good.
4. compare with overseas equipment, gap is obvious, mainly shows continuity and modified effect aspect.
We can say that the backwardness of the powder surface modification equipment of China seriously restricts the development of surface modification deep process technology.Since the nineties so far, achieve initial success.These stage achievements comprise two aspects:
1. introduce external continuous modification type.
1) .PS series powder surface modification machine.By the non-ore deposit of former Beijing Postgraduate Dept., Wuhan Polytechnic Univ. to develop successful PSC series powder surface modification machine jointly with the blue or green mining equiment in Qingdao Co., Ltd be the special equipment of surface chemical modification, it has advanced design, science; Can produce continuously, output is high, and energy consumption is low; Automaticity is high, and labor strength is low, no dust pollution; And the surface modifier consumption is few, characteristics such as clad ratio height.
2), combined type powder continuous modification system
This system is to be that the powder technology research department introduces a day present technique by Tsing-Hua University's material, the novel surface modified device of being produced by Zhangjagang City Machinery Plant of Light Industry.
3), three continuous powder surface modification machines of SLG type.Open safe nonmetal engineering company by He Jiangyang city, chamber, the non-ore deposit of Beijing graduate school of former Wuhan Polytechnical Univ and introduce Sweden AGMW company three high speed intense mixing surface modification machine (HSTP-3/1000) jointly, name and be three continuous powder surface modification machines of SGL type.
2. the cold unit that stirs of height is reformed.
1) semi-automatic intense mixing modification unit.By professor Huang Rui of Sichuan University design, produce (model: BMD-1000) micronization modified unit by Zhangjagang City, Jiangsu Machinery Plant of Light Industry.
2) the cold unit modifying machine that stirs of superfine powder height.By the cold unit modifying machine that stirs of the novel height of superfine powder that the Far East, Qingdao plastic engineering company manufactures and designs, produced 2L+6L laboratory unit, and applied for national patent.
