Woodworking : How to make your own strong casein wood glue from milk - burn skin care products
Safety first. action).
Always deal with chemicals based on the manufacturer's advice and any other precautions you can find.
Use gloves and goggles.
Avoid Burns and spills and reactions with incompatible objects.
Don't mix chemicals unless you know the results well before you do.
Some chemical mixtures may burn or explode or boil.
Do not eat chemicals if they are toxic.
Prepare your work space properly and have an assistant.
Use protective clothing and know how to contact the poison center for advice in case of emergency. In short -
Risk on its own. What ?
Glue of milk? Almost.
You need to separate the cheese.
For this reason, mild acids and some heat will work.
In addition, you need to use skim milk powder. Casein -What is it?
Cheese is a protein.
It is sometimes called case protein and you will find it in about 80% of the protein in milk.
By the way, this is a kind of metal.
So you should understand why it can be very difficult.
You might even find it a component of nail polish.
It is not condensed by heat.
So how do you extract from milk?
The answer is acid.
You may be interested to know that a protein enzyme found in the calf's stomach, called the milk gel, also extracts tysin.
(Think about the next time you like it
But keep in mind that it is reported to be good for your teeth.
The fact that the cheese is quite drain means that it is not soluble in water is a good feature for the gum. About the glue.
In ancient China, craftsmen produced a very good waterproof gel with a little lime of skim milk and curd enzyme.
You can do similar things with skim milk and vinegar.
We will discuss this issue later.
Although it is very waterproof, full permanent immersion can destroy this combination.
The same is true of microorganisms, however.
As a result, you may find that a commercial preparation also contains a fungal killer, but for non-humid interiors and even loads
With the structure, you can skip the fungal killer.
Do you use more today? No.
Formaldehyde-based glue is also strong, but more moisture-proof.
This is a shame because it turns out that the butterglue has been in use for 50 or 60 years.
For example, the Central station of Sweden's Stockholm Central was built between 1867 and 1871 using butterglue on huge laminated arches.
World War II fighter jets also have a butterglue structure.
Germany or Switzerland(ish).
Should I use more today? Yes.
It is possible to make butterglue at much lower cost than modern similar products.
Formaldehyde is an annoying chemical, but a simple butternut glue without lime or a fungal killer is not toxic.
Concentrated lime burns the skin
So only use it very carefully.
Skim milk powder. Water. White vinegar. Baking soda. 1.
Instructions for each pack of diluted skim milk powder are 100 ml. Put into a pan.
Add 15% ml (ml per month, 100 ml liquid ). 2.
Gently heat and stir.
Once it sets, remove it from the heat.
If you heat too much, the glue will be ruined. 3.
Filter liquid and condensed milk through paper filters. 4.
Clean the cheese to remove the traces of vinegar. 5.
Add 1/2 teaspoon baking soda to the condensed milk and stir it carefully with a small flat stick.
Add a drop of water at a time when stirring until a typical glue is reachedlike texture.
If you want to make a butternut powder that can be used with a variety of recipes, then after the fourth point.
Press the cheese with a paper towel on it to remove most of the moisture and make it hard and dry.
You can then restore it to powder.
Do not mix alkali before this stage, because the powder will lose its performance over time.
The quality of the glue depends on the low fat and acid content.
That's why you start with skim milk and why you wash away the vinegar. Bi-
Carbonated acid in soda is an alkali that, of course, neutralizes vinegar.
Alternative lime for Bi
Replace bi with sodium hydroxide-
Long term use of soda water with high strength glue, but will sacrifice some water resistance because sodium hydroxide is hydrophilic, which means it will "suck in" water molecules.
If you want to make a powder containing alkali, then you can use sodium hydroxide.
This is not a water mirror, but it turns into sodium hydroxide when you finally add water.
In terms of volume, chloro-phenol or its sodium salt is 5%.
Weight (any unit )-assume powder.
Accurate weighing scales are better than volumetric weighing.
(Sodium hydroxide) is "caustic sodium", also known as Iye and sodium hydrate.
Because it burns the skin, care must be taken.
) Also known as cooked lime, hydrated calcium or pickled lime. Using the glue.
The working time of the glue is longer
Time is easy to spread, but too much water can have a negative effect on the intensity.
The glue will stain some wood and too much water will cause more stains. A jelly-
Just as consistency will be strong.
It works for a short time.
Time can be difficult to spread.
Your goal should be warmth.
Hold the wooden head for 2 to 4 hours.
If the temperature is high, it will dry faster.
Hardwood glue takes more time than Cork glue.
You can use the machine in about 6 hours.
The glue is hard and will blunt your tools, so be sure to make them sharp and keep them sharp.
