1. Sand and dust test chamber: blowing dust
1. The dust particles are angular silica powder. According to the mass calculation, the silica content is 97% -99%, which is composed of the following sizes:
a. 100% through the screen with a pore size of 150μm;
b. 96% ~ 92% pass through a screen with an aperture of 106μm;
c. 88% ~ 92% pass through a screen with an aperture of 75μm;
d. 73% ~ 77% pass through a screen with a pore size of 45μm;
2. The requirements of temperature, relative humidity, wind speed, dust blowing concentration and test duration are shown in the table below.

2. Sand and dust test chamber: sand blowing
1. The grit should be quartz sand. According to the quality calculation, the silica content is more than 95% and consists of the following sizes:
a. 0.5% ~ 1.5% can't pass the sieve with pore size of 850μm;
b. 1.2% ~ 2.2% can not pass through the screen with a pore size of 600μm;
c. 13.8% ~ 15.8% can't pass the sieve mesh with pore size of 425μm;
d. 36% ~ 38% can not pass through the screen with a pore size of 300μm;
e. 27.6% ~ 29.6% can't pass the sieve with pore size of 212μm;
f. 11.7% ~ 13.7% can not pass through the screen with a pore size of 150μm;
g. 4.2% ~ 6.2% can not pass through the screen with a pore size of 150μm;
The grit should be quartz sand with sub-angular structure, with an average roundness factor (Krumbein value) of 0.2 and a Mohs hardness of 7. Aeolian sand in desert areas can be selected for preparation.
2. Sand blowing concentration
a. For test samples that may be used in the vicinity of aircraft (such as helicopters) that may be launched, taxiing, and flying at low altitude on unpaved ground, the sand blowing concentration is 2.2 ± 0.5 g / m³;
b. For test samples used near vehicles traveling on the ground, the sand blowing concentration is 1.1 ± 0.25 g / m³;
c. For test samples that are only affected by natural conditions, the sand blowing concentration is 0.177 g / m³.
3. The requirements of temperature, relative humidity, wind speed and test duration shall be in accordance with relevant regulations.
Ceramic Kamado Grill
Ceramic kamado grill (also called Kamado Barbecue Grill, Ceramic Grill, egg shaped barbecue grill) is a high-end outdoor barbecue equipment that combines high efficiency, environmental protection and beauty. This series of products uses high-quality natural ceramics as the main material.

Multi-function Kamado ceramic barbecue grill
How to use this ceramic Kamado BBQ grill?
1.Open the upper cover of the oven and put charcoal into the furnace. You can put 1-2KG at a time. (The oven saves charcoal and can be used by one person according to the specific situation. Put 0.8KG of charcoal and it can be used for 3 hours)
2.Use an electronic igniter or a special igniter for the oven to ignite the charcoal (for safety, it is strictly prohibited to use gasoline. Use flammable liquid fuels such as sesame to ignite.) When it is not very hot, you can first put the grill grid and wait for the charcoal to burn fully.
3.When most of the charcoal is ignited, simply spread the charcoal evenly to allow the charcoal to burn more evenly. Then you can put food on top of the grilling net (large pieces of meat can be cooked first to make it more delicious.). Then cover the lid and adjust the temperature by shaking the top and air door, and then wait for the food to grill. During this period, you can open the lid to watch the food grill. (During the barbecue process, if you need to add charcoal, you can open half of the grill net, make an opening, and then add charcoal.)
