Description

A kind of spices grinding glass, a kind of spice grinder and production method thereof
Technical field
The present invention relates to spices processing technique field, be specifically related to a kind of spices grinding glass and a kind of spice grinder production method.
Background technology
The mill of the mill (whether existing mill is also homogenous configuration) comprising core grinding and be engaged in core grinding outside is conventional spices processing units, orders about the two backwards rotation and just can be placed in the perfume particle grind into powder between mill and core grinding abrasive surface.Its core grinding of existing mill and mill adopt pottery or metallic substance to make usually, and the hardness of this type of mill and corrosion resistance all can not meet the requirement of spices grinding step.In actual applications, the abrasive surface of above-mentioned core grinding and mill is is easily wearing and tearing or is being corroded, and causes the mill efficiency of mill efficiency especially smooth surface, material that humidity is high to decline, and frequently changes core grinding or mill will increase production cost again on foot.The usual tool special odor of mill be simultaneously made up of pottery or metallic substance, in process of lapping, product becomes easily infected by peculiar smell, and quality is declined.
Summary of the invention
In view of this, an object of the present invention is to provide a kind of hardness high, corrosion resistant spices grinding glass.
Another object of the present invention is to provide the spice grinder that a kind of hardness is high, efficiency is high.
Another object of the present invention be to provide a kind of can large-scale promotion, improve the spice grinder of spices mill efficiency.
First object of the present invention is achieved through the following technical solutions: a kind of spices grinding glass, and it is specifically made up of the composition of raw materials of following weight part:
SiO 265-73 part;
Al 2o 30.1-2 part;
CaO7-9 part;
MgO0.1-1 part;
Fe 2o 30.01-0.2 part;
R 2o15-20 part;
Hardness reinforcer 1-3 part;
Described R is Na or K.
Further, described hardness reinforcer is made up of following material:
ZrO 210-15 % by weight;
Cr 2o 322-37 % by weight;
TiO 235-40 % by weight;
NaI8-33 % by weight.
Glass material has higher hardness, not easy to wear during for grinding spices, the high and long service life of mill efficiency.Meanwhile, glass also has stronger corrosion resistance, is particularly conducive to the spices that grinding corrodibility is strong.But the grinding step that the hardness of existing glass is still not enough to tackle high strength is produced, and contriver finds under study for action, adds by ZrO in frit 2, Cr 2o 3, TiO 2, the hardness reinforcer made with certain proportion of NaI, the composition of other compositions is optimized simultaneously, significantly can improves intensity and the toughness of made glass material, during for high strength grinding spices, not easy to wear cracked, thus there is higher mill efficiency.In addition, glass material provided by the present invention has stronger corrosion resistance, is applicable to grind the higher material of humidity, more easy to clean and can keep the stable of product odour.
Second object of the present invention is achieved through the following technical solutions: a kind of spice grinder is made up of above-mentioned spices grinding glass.
Above-mentioned a kind of spice grinder production method, specifically comprises following operation:
According to above-mentioned ratio by described SiO 2, Al 2o 3, CaO, MgO, Fe 2o 3, R 2after O, hardness reinforcer stir repeatedly, compound is dropped in melting unit and make it heat fused, mixing, form homogeneous glass melt; Glass melt is carried out clarifying treatment, after injecting mould anneal, just obtains described spice grinder.
Described repeatedly stirring refers to and repeatedly stirs 5 times with the rotating speed of 150-450 rev/min.
The rotating speed improving stirrer can make each feed composition mix more fully thus obtain homogeneous product.But for some raw material, excessively slow stirring velocity is difficult to make it fully mix, and too high mixing speed easily causes the cracking of himself structure.The rotating speed of above-mentioned stirrer is that contriver is preferred according to the physical property of the various feed composition of the present invention, within the scope of this, can ensure that each component of raw material can mix, can effectively prevent raw material generation cracking and lose efficacy again.Described stirring repeatedly refers to the mixing direction alternately changing stirrer, so just can promote the mixing of each feed composition further when not increasing rotating speed.
Described heat fused temperature is more than or equal to 1600 DEG C.
Temperature of fusion of the present invention sets according to the character of each feed composition, and when temperature of fusion is more than or equal to 1600 DEG C, each feed composition fully can dissolve and have lower viscosity, is conducive to the mixing of each component.
Further, described clarifying treatment comprises bubble removal step and absorbs operation; Described bubble removal step is in the subnormal ambient of-100-150KPa for making described glass melt be warming up to more than 1750 DEG C and making it be in gauge pressure; Described absorption operation is make the glass melt after bubble removal step process be down to 1550 DEG C with the speed of 5 DEG C/minute.
Bubble in glass melt will cause the decline of the finished product hardness, makes it easily to wear and tear in the course of the work and break.Therefore, the present invention is provided with bubble removal step, and under 1750 DEG C of these temperature condition, glass melt of the present invention has lower viscosity, and the bubble in Glass Containers is easy to depart from; Simultaneously above-mentioned bubble removal step is carry out in the subnormal ambient of-100-150KPa in gauge pressure, is conducive to the entrapped air pockets removed further in glass melt.
With the speed of 5 DEG C/minute, the temperature of glass melt is down to 1550 DEG C, is conducive to promoting glass melt fundamental change, promote the quality of final obtained spice grinder.
Further, described anneal is make the glass melt in mould be down to 1500 DEG C with the speed of 3 DEG C/minute, then is down to 1400 DEG C with the speed of 5 DEG C/minute, is finally down to 30 DEG C with the speed of 2 DEG C/minute.
Contriver for the character of spices grinding frit of the present invention and the demand of performance, is studied the parameters of degeneration treatment process especially.The above-mentioned speed with 3 DEG C/minute of final acquisition is down to 1500 DEG C, then is down to 1400 DEG C with the speed of 5 DEG C/minute, is finally down to the technical scheme of 30 DEG C with the speed of 2 DEG C/minute.In this anneal operation, hardness, the toughness of spice grinder, resistance to wear, corrosion resistance promotes further, finally obtains a kind of efficient, high strength, spice grinder corrosion-resistant, wear-resistant and easy to clean.
Hinge structure of the present invention, has following beneficial effect:
1. the present invention designs every feed composition of spices grinding glass and consumption thereof and optimizes, and uses by ZrO especially 2, Cr 2o 3, TiO 2, the hardness reinforcer that mixes with certain proportion of NaI, effectively improve the performances such as the intensity of obtained spices grinding glass, toughness and resistance to corrosion; Spices grinding glass of the present invention be particularly useful for manufacturing spices grinding produce in instrument and device, there is higher mill efficiency and easy to clean, the advantage such as the life-span is longer.
2. the invention provides a kind of production method of spice grinder, the method selects spices grinding glass of the present invention raw material manufacture spice grinder the most, characteristic for spices grinding glass of the present invention all designs melting process, parameters such as clarification operation and annealing operation etc., the properties of spices grinding glass of the present invention is not fully exerted, final acquisition a kind of efficient, high strength, spice grinder corrosion-resistant, wear-resistant and easy to clean, be conducive to enhancing productivity and quality product when dropping into actual production.
