Source masterbatch

Masterbatch full name plastic masterbatch, masterbatch alias is developed in the 1980s to stand up a plastic processing aid, it is an excess of chemical additives, carrier resin and dispersant composed . pp masterbatch is the aggregate of the extraordinary amount of pigment (dye) contained uniformly attached to the resin obtained. Masterbatch refers plastic molding process in order to facilitate the operation of the various additives, fillers, and a small amount of carrier resin required to be mixed and kneaded through an extruder and other measuring equipment, mixing, melting, extruding out, pelletizing and other processes to obtain pellets, called masterbatch. Masterbatch by a carrier resin, various fillers and various additives composed. Masterbatch additive or filler content limits than the actual requirement of plastic products in several times to ten times higher. In the molding process, the amount must be based on the relevant content of the component in the masterbatch and actual products need to be added, the adjusted ratio of masterbatch and the matrix resin. masterbatch glow can usually be divided into ordinary filling masterbatch (referred to as filling masterbatch) and functional masterbatches, such as masterbatch, anti-droplet masterbatch.

The definition of gravel and rock

decorative gravels refers weathered rock by the water flow from the long-term particle transport is non-angular natural aggregates of 2 ~ 60mm. Sediments classification in one name. Often the symbol G represents. It refers to the average particle size greater than 1 mm of rock or mineral debris. Average particle size, can be broken down into the gravel, boulders, coarse gravel and fine gravel are three: the average particle size of 1-10 mm, called fine gravel; 10-100 mm, called coarse gravel; greater than 100 mm , called boulders. Gravel after cementation diagenesis, called conglomerate or breccia.
decorative rocks is a natural output with stable outlook mineral or glass aggregates, combined together in a certain way. It constitutes the material basis of the crust and upper mantle. By cause into igneous rocks, sedimentary and metamorphic rocks. Among them, the magmatic rocks by high temperature molten magma at the surface or underground rock formed by condensation, also called igneous rocks [5]. He said discharge surface magmatic extrusive rock or volcanic rock, underground condensed called intrusive rocks.

What is the role gravel

stone gravel refers weathered rock by the water flow from the long-term particle transport is non-angular natural aggregates of 2 ~ 60mm.Sediments classification in one name. Often the symbol G represents. It refers to the average particle size greater than 1 mm of rock or mineral debris. Average particle size, can be broken down into the gravel, boulders, coarse gravel and fine gravel are three: the average particle size of 1-10 mm, called fine gravel; 10-100 mm, called coarse gravel; greater than 100 mm , called boulders. Gravel after cementation diagenesis, called conglomerate or breccia.stones for driveway of the stones in the road, the road is more robust.
Gravel from the exposed surface of the rocks formed through weathering; often deposited in the foothills and piedmont; or due to water erosion after being crushed rock to produce after fluvial deposition; after forming a conglomerate or breccia cemented gravel.

Luminescent materials used in the night

Luminescent materials used in the night
Easy way is to use the crystal clear finish mixed directly with luminous , stir evenly. Use luminous : You can use luminous paint be brush, roller , spraying , knife coating, curtain coating and other processes . When the light-emitting layer reaches a certain thickness , in order to obtain the ideal brightness, thus emitting coating should be at least 100-150um ( spraying twice ) . If the background is not white , glow in the dark film polyurethane paint base, until dry and then spray white luminous paint . In the light emitting overprint varnish coatings can improve the coating gloss and weather resistance. Using now , how much with the number , according to construction requirements , use paint thinner to adjust the viscosity.
Good transparency optional nature of neutral or weakly acidic organic resin , such as: a polyurethane resin, acrylic resin , epoxy resin, polyester resin , PVC resin, a polyvinyl butyral resin. Luminous powder luminous powder can choose different types for different purposes . glow in the dark material of 20% -50 % of the total ( weight ratio ) , or light emitting luminance and luminous time to choose the amount of luminous powder . To reduce sedimentation , use of high -viscosity resin or anti-settling agent , and stirred before use uniform.
