Cons of Artificial Grass

Posted by Unknown Monday 25 January 2016 1 comment
Artificial turf serves as a best alternative to natural grass in the domestic or commercial area. It is the widely used to cover the surface of tennis and other grounds in recent time. The reason behind of more use of artificial turf is that its reliability. It is convenient for those people who want to have lawn, but doesn’t require much maintenance and care. People only know the advantages of the artificial grass, but it has many hidden disadvantages. Some of the disadvantages are:

- Cost

It is inexpensive to install and cost is included grass removal, surface preparation and artificial turf material which is used during the installation. There are many options which increase the cost of turf for example: extra drainage system, temperature control system.

- Environmental Effect

Natural grass has a cooling effect when the atmosphere is hot, but artificial turf does not do so. It absorbs the heat and makes the surrounding air hotter. Hidden water system can keep the cool grass.

- Maintenance

Artificial grass requires extra care for the maintenance. You need to spray the disinfectant to kill bacteria/ microorganisms. Sanitation of the lawn is also anxiety. You will need to clean up any messy thing which could be infected human body. 

- Chemicals Impacts

Toxic metals including lead, plasticizes, etc. have many harmful effects on human body parts included kidneys, lungs, reproductive organs and liver. Synthetic grass industry used recycles tires to make infill that effect our environment, but another infill is silica sand which are commonly used in these days. It absorbs extra moisture and kills bacteria. Recycles tires also increases breathing problems for an asthmatics patient because of grass dust.

- Bacterial Breeding Ground

It is the best place for bacteria that grow in the artificial grass. Human blood, body cells and sweat are also remains on it which helps the microorganism to grow in it.

Which one is better: Artificial Turf and Natural Grass?

Both grasses have their own pros and cons. As above mention the cons of artificial grass, it is right for only commercial areas like playground, but not good for housing lawns because many health problems are related with it.

Silica sand - Mould making Process

Posted by Unknown Thursday 21 January 2016 0 comments
As we know that metal manufacturing companies uses a sand mould to shape melted metal. It is a process that dates back centuries, but still this basic process is not changed because it is inexpensive. Foundry sand is essential to metal casting industry. Silica sand is compatible for mould casting because of the high union point and low rate of thermal expansion. Once the mould casting process is completed, the silica sand mould is broken into parts and sand is recycled to make new mould.

The basic Principles of sand casting have not changed over the year. The idea is to 1. Mix silica sand and water, 2.pack the sand into mould, 3. Press a model in the sand so that mould can be made. Mould sand mixture is depends upon the type of the metal which has been cast. The mould is divided into two parts one is upper half is called cope and another one is bottom half is called drag.

How the mould is made from sand


* Already designed pattern is placed into mould.
* Half fill the mould box with sand (mixture of sand and water) and press the sand evenly, so that the pattern is printed on the sand.

first half the mold

* Same step is repeated for second half pattern.

second half the mould

* Lubrication is also applied to the surface of the mould. Lubrication improves the flow of the metal and improves the surface of the final part
* After mould making, the mould is clamped to prevent the loss of any material while filling metal.


* Clamped mould is filled with the molten metal is called pouring and leave for it to set.

* Remove the clamp and put the sand mould to vibrate table. It shakes the mould and removes the dust from the final part.

Pool Sand Filter Media Working Process

Posted by Unknown Saturday 9 January 2016 1 comment
Sand Filter is commonly used for water purification for treating impure water to produce a portable product, is also called slow sand water filter. The process of filtration is usually repeated to ensure satisfactory removal of unwanted particles in the pool water. It is an important part of maintaining a health swimming environment. Proper Maintenance of filter requires that the silica sand of filter media is regularly changed to get hygienic water in the pool. The filter also removes the body oils and other minerals which infected human body while swimming.

How sand Filter Work


Sand Filter work on simple mechanism, the water passes through the sand from the top to bottom. A layer of gravel and sand (large particle) is set on the top of the tank. Small particle sand holds the all microorganisms and other large dust particles.



How to make Sand filter at home


Making a sand filter for Swimming pool is not a hard job, just few things required for it. A pool Filter needs cleaning average a year.

Required material for Sand Filter


* Large Plastic container
* Silica Sand and Gravel
* Nylon/cotton sheet (optional)
* High pressure water pump
* Pipe/tube

Assemble process of sand filter


* Cut the hole with the help of drill on the narrow container ends. Make sure that diameter of the hole is same of plastic pipe.
* Insert the tube into the hole and sealed with silicone caulking to ensure it is waterproof
* Add Gravel and silica sand Layer into the container.
* Insert the nylon cloth layer on the top of the container. It holds all large particles which come in during the filtration process. The best thing is that collected large particle can be easily removed manually after the few months.
* Add Plastic tube on the top of the container and attached to the high pressure water pump.

What is sand blasting and how it's work

Posted by Unknown Monday 4 January 2016 0 comments
Sandblasting is the process to clean with a jet of sand driven by compressed air. Sand is the most commonly used material, but since the lung diseases is extended by the cause of sand dust. Silica Sand Blasting uses compressed air, when the compressed air comes out from the nozzle with sand; it hit the material and cleans the surface.

How Sand Blasting Machine Works


 There are different types of materials used in sandblasting, but the basic principle is same. A pipe fitted with a nozzle is attached to the air compressor that the worker uses to direct the blasting material where it's needed. There are different adjustments to control the amount of air and sand pressure. Too high pressure can be damaged the surface of item and it is depends upon the material hardness.

Different Area Where Sandblasting Used:


1. To remove paint and rust:  It is used to remove the paint and rust of car, motorcycle, floor paint and other metal items. High pressure sandblasting is only performed on the hard surface; otherwise it ruins the surface of thin metal. It is very important, that’s how to safely operate.

Safety equipment for sandblasting operator:


a) Helmet:  It includes a head suspension system which allows the operator to move head, a view window with replaceable lens. Helmet must be consisting with air mask.

b) Hearing protection: use ear plugs so that sand dust doesn’t enter in the ear.

c) Body Protection: Body protection consists of various applications (Gloves, blast suit, long rubber shoes)
