Basic knowlegde of Ceramic Pigments

Generally speaking, Ceramic pigments consist of some combination of salts, metallic oxides, alumina, silica and natural clays. These different materials each convey different colors to the final pigment. A combination of zinc, chromite, cobalt and alumina, for instance, produces a blue-green pigment, with the ratio of chrome to cobalt allowing for a bluer or greener result. These mixtures exhibit more stability than oxides, natural coloring agents that can react with one another or with the heat of the kiln to spoil the intended result. An alcohol base serves as a solvent to keep the pigments from oxidizing.

The color pigment is made of the multi-purpose ceramic powder,Widely used in construction coating and glazed ceramic productsStable quality, Wide selection of colors. Pigments includes a mix of coloring and stabilizing agents such as metallic oxides, salts and other minerals.Ceramic objects fashioned from clay, glazed and fired in a kiln can take on a variety of colors through the addition of pigments.You can brush a ceramic pigment onto a completed pot or other object, or you can mix it directly into the clay or glaze. To ensure safety and achieve the desired results, you should always read the manufacturers' labels and note any temperature requirements or toxic ingredients.

Solution for plastic bag

• The solution is not a plastic bag ban, which is an emotional response which fails to strike at the heart of the issue; instead of a market-based solution, a ban shifts production to paper bags and compostable bags, both of which have heavy environmental consequences.
• The solution is not switching to paper bags or compostable plastic bags. A study on the life cycle of three types of disposable bags (single-use plastic, paper, and compostable plastic) showed that both compostable plastic and paper bags require more material per bag in the manufacturing process. This means "higher consumption of raw materials in the manufacture of the bags... greater energy in bag manufacturing and greater fuel use in the transport of the finished product. ...The added requirements of manufacturing energy and transport for the compostable and paper bag systems far exceed the raw material use in the standard plastic bag system." (from a peer reviewed Boustead Consulting & Associates report)
     - Plastic Tax: In 2001, Ireland implemented a plastic tax (or PlasTax); the first of its kind, this route acknowledges the fact that people will still occasionallyuse plastic bags. This market-based     solution discourages daily, thoughtless use of plastic bags by charging a nominal fee per bag at checkout. In a study by the Irish Department of the Environment it was found that plastic bag usage had dropped 93.5%. This breaks down to a drop from 328 to 21 bags per person each year.
     - A cultural shift away from use-and-toss culture: Each reusable bag can eliminate hundreds (if not thousands) of plastic bags.

What is Heat Shrinkable Sleeves?

Heat shrink tubing, also known as heat shrinkable protective sleeve, providing insulation for wires, cables and wire terminals. Has low shrinkage, soft flame retardant, insulation corrosion, etc., are widely used in a variety of wire harnesses, solder joints, inductance insulation and metal pipes, rods rust, corrosion, etc.
Flame retardant heat shrinkable tube, insulation, heat resistance, heat shrink tubing is a special polyolefin heat shrinkable sleeve material, but also called EVA material.
It has a soft and flexible. Heat (125 degrees) will shrink, widely used in a variety of wiring harness, solder joints, inductor insulation, metal pipes, rods rust and corrosion.
Commonly used in wire connectors, choose the appropriate heat shrink tubing, set on wire connectors, heated with a heat gun, heat shrink tubing shrink, put the joints stuck.

The influence factors of non woven geotextile demand

All factors affecting the artificial fiber growth can be more or less cause certain influence on artificial fiber as raw material for textiles, which impact on largest non woven geotextiles.
 
Population growth factors to influence than other non-woven fabric for clothing textiles are small. But if we take into account the important application of non-woven fabric in baby diapers in population growth, it is also an important factor. Natural fiber was partially replaced great effect on textiles, but has little effect on the non-woven fabrics, non-woven production because basically relies on artificial fiber. Since the establishment of the international economic treaties, making micro fiber, composite fiber, biodegradable fiber and new polyester fiber trade gain.
 
This is a great effects on the non woven geotextile, but the influence on clothing and knitwear textile little. Instead of textiles and other products: This includes being non woven geotextile, knitted textiles, plastic film, polyurea foam, wood pulp, leather and other substituted.
