POLISHING BLANKS

Italian Black Slate 152-25-7-4

Identical to  dark Thuringian shale in working properties, with the difference that this slate is a little harder, which is undoubtedly an advantage when working in Apexoid type sharpeners. The late produces a very moderate fine white suspension. Works  with any type of steel, removing residual scratches on the cutting edge. Superfinishing stone, which is recommended to use after   abrasives   F1000-F2000, or superabrasive 5/3, 3/2, 2/1, 1/0 micron. Each stone is supplied with a slur (a small suspension guiding stone). The recommended cooling liquid are water, oil.

Glossy leather 160-12-7, 160-25-7

Leather attached to aluminum blank for knife sharpening with pastes of fine grain sizes. The leather is polished  to make glossy surface to use, applying polishing paste and polishing the cutting edge of a knife.
You can use it without paste too. 

Rough leather 160-12-7, 160-25-7

Leather attached to aluminum blank for knife sharpening with pastes of coarse grain sizes. The leather is polished  to make rough surface to use, applying polishing paste and polishing the cutting edge of a knife.
You can use it without paste too.

Boron nitride powder,  wurtzite crystal structure, w-BN. 

This  wurtzite boron nitride powder was manufactured by shock compression (explosion in special military facility) of hexagonal boron nitride.  

Grain size: 6/10 micron, see particle size distribution diagram

Application:  anti-stick coatings, dry lubricant, high temperature resistant additive, synthesis of superhard materials.  

How to prepare  boron nitride anti-stick coating for protection of metals, glass, ceramics, composites, plastics and other materials. 

  Wurtzite boron nitride has a potential for manufacturing of advanced electronic devices, because such its properties as  as a wider band gap, higher thermal conductivity, and larger spontaneous polarization, are superior to Gallium nitride (GaN) and Aluminium nitride (AlN). 
Incorporation of a few percent of B in AlN and GaN is an important perspective in strain engineering and  developing deep UV emitters

According to Ioffe Institute, thermal expansion of wurtzite boron nitride is the lowest among other materials, so it ensures higher stability of coating layer under high temperatures. You can buy high temperature wurtzite boron nitride paste here.

Bonds: 
Resin bond: phenol-formaldehyde,  does not require lubricant, but you may use water (or water based cooling liquids) 
Metal bond: M2-01, copper-tin 
 
Grain size: Please select from the list, or read Technical information.  

The finest grain size is 0.5/0 micron (fine polishing) , the coarsest - 200/160 micron (rough grinding). 
In grain selection window you see grain sizes according to standards:
MICRON = MESH(GRIT) = FEPA

Preparation of sharpening stones
These stones require preparation (dressing), or they will be self-polished after sharpening of 30-50 knives. Then they will be of gold color and work well.
This is common issue for all manufacturers: abrasive grains are covered with bond, so you need to "release" them.

Use and cleaning of sharpening stones
Use any comfortable oil (baby, olive..) to prevent glazing. If glazed - clean with alcohol and toothbrush.

Maintenance (in 1-2 years), flattening/revitalization:
- resin bond stones - with silicon (silica) carbide powders on glass plate,
- metal bond stones - with FeCl.
   - 10 mins setting in 25% mixture (25 gr FeCl per 75 gr of water),
   - 10 mins polish movements (carefully draw "8") on glass plate.
 You may buy 100 gr. of FeCl in grain selection window. I sell it if you buy a stone.

The finest grain size is 0.5/0 micron (fine polishing), but we can make 0.25/0 and 0.1/0 micron. 

Coarse grain emulsions (14/10, 20/14, 28/20, 40/28, 60/40) will be packaged in eyedroppers (see photo), because the coarser is grain, the more difficult is to spray emulsion. 

This emulsion shows excellent non-drying(delayed drying) properties:
- Unlike other common water-based products on the market that dry out easily, this emulsion is very suitable for lapping as it can be used for a long time without particle clog and fixation(less impregnation) due to fast drying.
- It works really well on strop media that is harder than leather, like copper(half impregnation/half loose), cast iron, granite, CGSW hard strop.
- Excellent deburr properties in loose abrasive's rolling abrasion mode.

Why it's important:
As you know, once you apply diamond/CBN to leather, it will work almost forever. However, for non-absorbent surfaces, most emulsions will lose most of its abrasiveness when washed out -> frequent reapply required = higher consumption and higher costs.

Shake it well before use
Coarse grains (> 5/3 micron) are heavier, so shake it even better,
if you still see residue on the bottom - It wouldn't hurt to stir it with thin stick.

WURTZENITE™ BORON NITRIDE, HIGH TEMPERATURE RESISTANT PASTE 


 
Net weight: 50, 150, 500, 1000 gr.
 
Content: wurtzite boron nitride powder (10/7 micron), 40% in water/alcohol soluble composition.

Properties: boron nitride thermal paste, high temperature resistance and conductivity, dielectric strength (eliminates the risk of shorting out) 
Thermal conductivity  2.7 watt/centimeter/°C
(Thermal conductivity of  wurtzite boron nitride powder- 7.4 watt/centimeter/°C compared to silver with 4.29 watt/centimeter/°C)

Grain size:  10/7 micron  (see particle  size distribution diagram of wurtzite boron nitride powder)
  
Application:
- mold release;
- detaching (dismantling) and protective for high temperatures (up to 2000 °C);
- anti-stick coating;
- thermal conductor, including for more effective heat distribution in 3-d printers' hot blocks, reducing clogs and making removing nozzles easier;
- facilitates cutting of hard materials, extends the service life of cutting tools, provides a lower operating temperature.

How it works: composition  evaporates under high temperature, leaving boron nitride on the surface, which, to some extent, is also stress resistant. On the first heating of wet surface, there is a mild burning plastic smell, which is the glycating agent evaporating, so for first indoor use ventilation is needed  or let paste dry. 
If smell is an issue, buy wurtzite boron nitride powder and make water mixture (1:1 by weight).

Directions of use: 
- General:  apply uniform layer to the surface and let it dry; 
- 3-d printer cartridges (thermistor & heater) and heat breaks: coat the surface, install while the paste is still wet and let it dry before heating up;
- Nozzles: apply small amount to threads of the nozzle (do not apply the paste  to the threads of the heater block), install the nozzle while the paste is still wet and let it dry before heating.

 Advantages: 
- Thermal expansion of wurtzite boron nitride (according to Ioffe Institute) is approx. 1.5 lower than that of hexagonal boron nitride and other heat resistant materials. Which means higher stability of coating layer under high temperatures (<2000 °C = 3632 °F);
-  Thermal conductivities of wurtzite crystal, parallel and perpendicular to the axis, are identical. Which means higher stability of thermal properties in comparison to other heat resistant materials, including such forms of boron nitride as hexagonal and cubic.
