Jiangsu Pulai Ke Hongmei Masterbatch Co., Ltd. has more than 40 professional production lines, annual production capacity of 3 million tons, annual sales of 300 million yuan. Since 2014, the company has introduced 6 sets of continuous mixing production lines from the United States and Germany successively. All kinds of ancillary equipment are provided by top international professional manufacturers. Large production capacity, high degree of automation, a comprehensive catch up with the traditional domestic masterbatch production process. The following introduces you to master masterbatch entry knowledge!
First, what is the masterbatch?
Color Masterbatch, also known as color masterbatch (ColorMasterBatch) is a new type of polymer materials for coloring agents, also known as pigment preparation (PigmentPreparation). It consists of three basic elements: pigment or dye, carrier and additive. It is an aggregate obtained by uniformly loading a super-constant pigment or dye into a resin, which is called Pigment Concentration. Therefore, his The tinting strength is higher than the pigment itself. Simply put, masterbatch is an aggregate made by uniformly loading a super-constant pigment or dye into a resin.
Second, the basic composition of the masterbatch which?
Paint or dye
Pigments are divided into organic pigments and inorganic pigments
Commonly used organic pigments are: phthalocyanine red, phthalocyanine blue, phthalocyanine green, red fast light, macromolecular red, macromolecular yellow, permanent yellow, permanent purple, azo red
Common inorganic pigments are: cadmium red, cadmium yellow, titanium dioxide, carbon black, red iron oxide, yellow iron oxide, etc.
2. Vector
The carrier is the matrix of masterbatch. Special masterbatch resin and resin products generally choose the same resin as a carrier, the best compatibility between the two, but also to consider the carrier fluidity.
Dispersant
Promote uniform dispersion of pigment and no longer aggregate, the melting point of the dispersant should be lower than the resin, and the resin has good compatibility, and the pigment has better affinity. The most commonly used dispersants are: polyethylene waxes, stearates.
4. Additives
Such as flame retardant, brightening, antibacterial, antistatic, antioxidant and other varieties, unless requested by the customer, under normal circumstances, the masterbatch does not contain the above additives.
Third, what color masterbatch points and grades?
Masterbatch classification methods commonly used are the following:
According to the carrier classification: such as PE masterbatch, PP masterbatch, ABS masterbatch, PVC masterbatch, EVA masterbatch, etc.
According to use classification: such as injection color masterbatch, color masterbatch, spinning masterbatch and so on
The varieties can be divided into different levels, such as:
1. Advanced injection color masterbatch:
For cosmetics boxes, toys, electrical shell and other advanced products.
2 ordinary injection color masterbatch:
For general household plastic products, industrial containers.
3. Advanced blown film masterbatch:
Blow molding for thin products.
4. Ordinary blown film masterbatch:
For general packaging bags, woven bags, blow molding.
5 spinning masterbatch:
Spinning for textile fiber coloring, masterbatch pigment particles fine, high concentration, strong tinting strength, heat resistance, light resistance and good.
6. Low Color Masterbatch:
For the manufacture of low-quality color of the low-level products, such as trash, low-level containers.
7. Special color masterbatch:
Is based on the user specified for the product of plastic varieties, use the same plastic as the carrier manufactured by the masterbatch. Such as PP masterbatch, ABS Masterbatch were selected PP, ABS as a carrier.
8. General Color Masterbatches: Some type of resin (often PE with a low melting point) is also used as a support but it can be suitable for coloring other resins than their carrier resins.
General color masterbatch is relatively simple and convenient, but more disadvantages, it is recommended that users choose a special masterbatch.
Special masterbatch heat-resistant grade is generally compatible with the plastic used for products, at normal temperatures, you can rest assured that use. Only in the following circumstances will cause varying degrees of discoloration, first, the temperature is beyond the normal range, one downtime too long.
