How do we transport rubber?
Rubber is a material which requires special care, given its easy contamination by external factors. To prevent its contamination, rubber must be transported on metal pallets rather than on the conventional wooden versions.
How is synthetic rubber shipped?
Granulated synthetic rubber is packed in polyethylene sacks and palletized. The polyethylene sacks can additionally be packed in cardboard boxes and then palletized. Flexible bulk packages (IBCs, e.g. 500 kg big bags) can also be used as packaging.
How is latex shipped?
Shipment / Storage / Risk factors Latex is carried in bulk or in drums . In vessels with deep tanks the surface of the tank is first coated in candle wax or similar substance to allow the tanks to be sliced of residue on discharge. Drums of latex are usually coated on the inside and can be loaded in a 20GP container.
How is rubber taken from trees?
Rubber tapping is the process by which latex is collected from a rubber tree. The latex is harvested by slicing a groove into the bark of the tree at a depth of one-quarter inch (6.4 mm) with a hooked knife and peeling back the bark. Jungle rubber is expected to resemble primary forest in its hydrological functions.
How do you store natural rubber?
Safe Storage of Rubber Products
- Temperature: Storage temperatures between 72° F (22° C) and 32° F (0° C) are ideal.
- Humidity: Rubber products should not be stored under conditions of high or low humidity.
- Ozone:
- Sunlight:
- Oils, Solvents & Corrosive Liquids:
- Fumes:
- Insects, Rodents & Other Vermin:
How do you maintain latex in liquid state?
The standard industrial practice is to preserve latex is by adding ammonia so that thae concentration is 1% by volume of latex. Ammonia prevents the growth of bacteria in latex.
Can rubber be made from petroleum?
Crude oil is the principal raw material in synthetic rubber. Approximately 70% of all rubber used today is synthetic.
How does latex become rubber?
The latex is a sticky, milky and white colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called “tapping”. The latex then is refined into rubber that is ready for commercial processing. In major areas, latex is allowed to coagulate in the collection cup.
How do you process rubber in latex?
The most common method of extracting the rubber from latex uses coagulation, a process that curdles or thickens the polyisoprene into a mass. This process is accomplished by adding an acid such as formic acid to the latex. The coagulation process takes about 12 hours.
What is rubber processing?
Rubber processing consists of four basic steps: (1) mastication, when the elastomer is sheared and the molecules are broken down to give easier flow, (2) mixing, usually carried out immediately after mastication, when additives are incorporated, (3) shaping of the viscous mass, for example, by extrusion or molding, and …
