Furniture Finishing Food Grade

Selection of materials and finishing applications for products that deal directly with the food proved to be more complicated than finishing for wood furniture. Apart from having to be physically stronger, the type of chemicals that must be removed also so much more.
This type of finishing is known as Food-Grade, in accordance with its function. All kinds of products used at the time of preparation, food storage process and become part of a product that needs to be checked.

PHYSICAL PROPERTIES
To check and ensure that the type of finishing on a product qualifies as a food-grade, we can do some physical testing. Of course, for the most accurate results we can do in a special laboratory with special equipment. How can we do a test with a more practical way?

1. Power Tie
Finishing needs to have a bunch of good resources on wood surfaces that are not easily peeled off the food brought during the process of food preparation and presentation. Tentangkayu.com's knowledge there is currently no specific standards regarding the testing method of a power belt finishing. There is a special method performed by well-known retailer to test the power tie.
Use a 5cm-wide masking tape and glue on the surface finishing 12-15 cm long and press with fingers so that the entire surface of the tape is attached properly. Then gently pull the tape ends with strength of approximately 125-140Newton/25mm. finishing the good should not exfoliate during withdrawal. One example type of tape is good for this test is a product of 3M brand Nr. 6893. 6893.

2. Resistance to scratches
This does not mean anti-scratch against hard objects such as knives, forks or other sharp objects. Practical method of testing with the push of a 1mm diameter steel ball on the surface finishing. Etching must transverse direction of wood fiber. The depth and scratch marks will show how much endurance finishing.

3. The durability of the color (of the risk removed)
This test is intended primarily for the type of finish paint color. Color finishing should stay in the wood surface. Similar to the function of a pencil eraser, the test can use a 16mm-diameter wood tool rounded edges so close to form the index finger. Then the tip is wrapped with a soft cotton cloth.
In accordance with international standards IOS-105-X12, the tip of 'finger' are driven back and forth on the surface finishing over several times with a load 9 Newton. Resilience finishing color is determined by the large color peel and stick to the fabric.

CHEMICALS REQUIREMENTS
For those of Europe or the U.S. consumer, chemical testing is far more important than the physical examination because of side effects that influence the chemical testing for human health. Chemicals (finishing) in the furniture directly related to food must be free from harmful chemicals.

Some indicators of safe finishing materials for products that relate directly to food:
1. Analysis of the sensor: Oil without color or fragrance is very mild.
2. Heavy metals including lead and cadmium (<1mg/kg); Mercury & Arsenic (<0.1mg/kg)
3. PAHs (polycyclic aromatic hydrocarbons), including Benz (e) pyren, Benz (a) pyren, Perylene, benzo (GHI) perylene, Anthanthren, Debenzo (a, h) anthancen with total Max. 25 µg/kg 4. Solvent residues including Benzene, Toluene, Ethylbenzene, combined elements of Xyloles, Chloroform, 1.1.1.-Trichlorethan, Tetrachlormethan, Trichorethen, Tetrachlorethen Not detectable level or <1 mg / kg. Except for Toluene and Ethylbenzene Max. 10 mg/kg.

It looks very difficult for us to avoid such chemicals because we can find it easily on the materials we use everyday. But again we ask the question again for those of you producers of related products, especially the cutting board (chopping board): Are changes in marketing strategy and attention to consumers must be made in connection with finishing material? And to us as consumers, did you ensure that the products you use at this time is 'healthy'?
