How to choose the best paints for your homes?

When remodeling your house, you have tons of things to keep in mind. The interiors, the flooring, the final layout and paints besides other things. When it comes to choosing paint for the home, all we commonly tend to consider is the sort of color and texture the paint has. These days there are such innovative patterns available that people get spoilt for choice, choosing abstract designing patterns for planning a masterpiece of a wall for their home.

However, we usually forget that paints are going to stay with us for a very long time and hence, there are other details that need to be considered than simply the colors and textures. Have you ever thought that paints might actually be harmful for you? Sometimes, manufacturers use harsh and cheap chemical reactive diluents in their paints and this might tend to have a very negative impact on the health of people staying in the home!

There are such reactive; polluting gases that the paints tend to exhibit at times that can lead to different health problems such as frequent headaches, breathing disorders, irritation in the eyes and so on. The reason for this is the harmful VOC components of the paints that are prepared cheap.

Doesn't that make it important for you to pay close attention to the details? You wouldn't want your family to suffer at the hands of something as meager as paint! So keep your eyes open to the details printed about the paint on its box. If there are harmful solvent dyes, or anything such as lead used in making your paint, it is the wrong choice! What is more, inquire with paint companies before you choose a box to color your home. Find out if there are any sorts of risks involved with their products and if you find even the slightest problem, look for better options.

It's a wise choice to look for organic paints because they are obviously much safer and healthier for coloring your homes. They shall not only give you a colorful wall, but also a surrounding where you will not have to worry about health hazards.

Researches well before you choose a paint. It's because it's not just a simple box of paint, but something that is going to determine your peaceful existence in your home for years to come. Choose for options that are safe and cost effective. And after that color your homes with panache, without having to worry about the disastrous effects it might have on you!

Various uses of Sodium Nitrite

The nitrite ion, NO2, plays a critical health function by restricting botulism causing bacteria and helps to prevent spoilage.

Also referred to as by other names such as diazotizing salt, sodium salt of nitrous acid, sodium nitrite is a chemical compound that offer benefits in different ways such as it is used in fertilizers, smoke bombs, food preservative, dyes and pyrotechnics, preservative in meats (such as bacon, ham and hot dogs), and more.

Chemically known as NaNO2, sodium salt of nitrous acid looks like small, yellow, off-white crystals, which are soluble in water! Some past studies has shown that diazotizing salt is a strong oxidant, flammable and highly toxic agent.
An antidote for cyanide poisoning, NaNo2 also play a vital role in medical industry, as this chemical substance is used in manufacturing medicines (for both human beings and veterinary) as a as a bronchodilator and as a vasodilator. The main purpose to use diazotizing salt in medications is that it works effectively to increase the flow of blood by dilating blood vessels and act as a vasodilator.
Further studies and researches is being undertaken in order to investigate the uses of this yellowish substance in heart attacks, treating sickle cell anaemia, pulmonary hypertension in children, and aneurisms of the brain.

NaNo2 is sometimes also known as natural substance as it is found naturally in several leafy vegetables including curly kale, spinach, lettuce, parsley, cauliflower, broccoli, and asparagus. During boiling process, the level of nitrate reaches to its lower level while it does not affect the nitrite levels.
Combination of sodium, nitrite, and oxygen elements, sodium nitrite is also used in injections for variety of purposes. Some of the most common uses of NaNo2 injections are given below:

Cyanide Poisoning:
According to the health conditions, NaNo2 injections are utilized in life cases of cyanide poisoning. This kind of injection is, generally, given through a hypodermic needle which is injected directly in the arm. To use this injection, nurses and health practitioner are provided the special training.

Sickle cell Anemia:
Another health benefit of sodium nitrite is that it offers effective treatment to those who are suffering with acute vaso-occlusive crisis sickle cell anemia. A past study has shown that sodium salt of nitrous acid is a safe medication that can improve the blood flow and provide body tissues with oxygen.

Vat Dyes’ Properties, Classification & Much More

Found amongst the oldest natural coloring substances used for textiles, the vat dyes offer first-rate fastness properties. They are so named because a vat (which means a bucket or a container) is used for the process of dyeing!
Although, other dyeing can also be done in a vat, but the term vat dyes specially describes the class of coloring substances that are applied to cellulosic fiber (fibers come from plants or plant based materials. For example, cotton) using a redox process.

Properties:
Here are some highlights of the common properties of Vat dye:
  • Superior color fastness properties, which are exceptional in other dye classes
  • Needs vatting for application
  • Water insoluble dyes
  • A number of colors can be produced
  • Rubbing fastness is not good, but is can be easily lessened with special treatments to the fabric
  • Especially used for cellulose fiber with PH (measure of hydrogen ion concentration) control.
Classification of Vat Dyes:
Depending upon the properties one popular classification of vat dyeing substances has been developed which is given below:
  • The 1N (indanthrene normal)-group of dyeing temperatures of 600C. In such dyeing substances no salt is added to the dye bath because they have high portion of leuco dyes for cotton.
  • The 1W (indanthrene Warm) - group of dyeing temperatures of 500C. In such dyeing substances some addition of salt is required so to aid exhaustion.
  • The IK- group of dyeing substances requires low concentration of NaOH with dyeing temperature of 200C.
One special type of vat coloring agents is light-oxidized vat dyes that use light rather than oxygen in order to produce wide range of color effects along with color fastness. Elaborately, these coloring agents which are chemically similar to the vat coloring materials developed in light rather than dipping in the oxygen-free bath and exposing into the air. Dye itself attached to the fabric.

Dyeing Process:
Most coloring substances, which require a reducing agent (the element in a reduction-oxidation that transfers electrons to other chemical species such as atoms, molecules, ions etc.) for solubilization, are less suitable than fiber-reactive coloring materials. The coloring agent is soluble in its reduced (oxygen-free) form. The fiber is dipped again and again in this oxygen free dye bath and brings out in the air where the reduced form of water-soluble change the color as the exposing to oxygen turns it into the water-insoluble form.
