Introduction

PNF Co has an innovational combination of methods to meet textile industries requirement. The most important advantages of the applied technologies are feasibility and efficiency in this problem.

In electro-oxidation process, a kind of electric current applied into the electrolytic reactor causes the colloidal impurities to de-stabilize, resulting in agglomeration and flotation and subsequent removal. Dissolved impurities contributing BOD/COD also get oxidized due to the oxidizing agents released by the electrolytic solution which changes them into a state that is either less colloidal and less emulsified (or soluble). Also, Color has been decreased during this process. PNF Co is using a special coated plate and also power source to improve the operation and also decrease power consumption of the electro-oxidation unit. Electro dialysis unit also is used to remove salts and other ionized contaminants and makes the water suitable for re use.

It is worth mentioning that the antibacterial activity of polymers reinforced with silver nanoparticles is stable and its high antibacterial efficiency has been observed against different species of bacteria. Silver ions and its compounds can kill a wide range of bacteria, while they have no toxic effect to the human body. Therefore, the use of silver in different forms is a common method of protection against bacteria. 

Introduction

Biodegradable plastic is plastic that decomposes naturally in the environment. This is achieved when microorganisms in the environment metabolize and break down the structure of biodegradable plastic. The end result is one that is less harmful to the environment than traditional plastics. Biodegradable plastics can be composed of bioplastics, which are plastics made from renewable raw materials. There are normally two forms of biodegradable plastic, injection molded and solid. The solid forms normally are used for items such as food containers, leaf collection bags, and water bottles.

Introduction

This product is nano-micelles containing curcumin with the ability to disperse and dissolve in water. Curcumin is poorly absorbed into the body because it is insoluble in water. Therefore, the dissolution of curcumin in an aqueous medium is of great importance. Micelle is a surfactant molecule aggregate dispersed in a liquid colloid. It is a nanosized vesicular membrane which becomes soluble in water by gathering the hydrophilic heads outside in contact with the solvent and hydrophobic tails inside, which is known as emulsification. Loading the curcumin in nano-micelles enhances its dissolution and dispersion in water and helps it to absorb into the body. In general, the most important biological effects of turmeric and curcumin are anti-inflammatory, antioxidant and anti-cancer effects.

Introduction

Petroleum resources are limited and the excessive use of non-biodegradable polymers has caused serious environmental problems. Therefore, degradable and/or biodegradable polymers have received more attention these days. Since synthetic polymers are expensive, the focus is mainly on natural polymers which are inherently biodegradable and can be promising candidates to meet different requirements. Among the natural polymers, starch is of main interest. It is regenerated from carbon dioxide and water by photosynthesis in plants. Due to its complete biodegradability, low cost, and renewability, starch is considered as a promising candidate for developing sustainable materials. Addition of starch to the synthetic polymers creates biodegradable feature but decreases mechanical properties. To deal with this problem, nanofibers are added to the polymers.

Depreciation of the automobile engine because of the increase in temperature and friction is the main challenge in the automobile industry. In this regard, improving the quality of motor oils has always been the main concern of the specialists. Motor oils containing nano additives are the latest technology for protecting and extending the life of automotive engine and oil through mechanical means instead of chemicals, which can deteriorate over time. The nanometer-sized diamonds suspended in the motor oil are completely dispersed in the oil and fill the pores of the metal, helping to sustain an oil film on the inner surfaces of the engine. The nanodiamond ball bearings transform the sliding friction that normally occurs between metal surfaces into rolling friction, thereby reducing heat, wear and engine drag. Lower heat helps to extend the life of the oil, and less engine drag increases fuel mileage.

Introduction

A detergent is a surfactant or a mixture of surfactants with cleaning properties in dilute solutions. Detergents are commonly available as powders or concentrated solutions. An emulsion is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable). Emulsions are part of a more general class of two-phase systems of matter called colloids. Nanoemulsions are emulsions in which the droplet sizes are less than 100 nm. A typical nanoemulsion contains oil, water and an emulsifier. Since microemulsions are thermodynamically stable systems in equilibrium, they are sensitive to changes in temperature and composition. Therefore, nanoemulsions are attractive for aforementioned applications because they are relatively the least sensitive to physical and chemical changes and they can be kinetically stable over long time scales. This product is an alcohol free nanoemulsion that is used as a detergent for cleaning and polishing a variety of surfaces. The products made by this company are as follows:

• Antibacterial cleaner spray for tablet and mobile
• Glass cleaner spray
