·AQSIQ announced the unqualified rate of export tires

A few days ago, the General Administration of Quality Supervision, Inspection and Quarantine announced the inspection and sampling of import and export commodities outside the catalogue in 2016.
The data shows that among Chinese exports, the tire failure rate is only 2.6%, which is the lowest.
Data show that from January to November 2016, China's tire exports totaled 429.087 million, an increase of 6.2%.
According to relevant sources, as technology advances and manufacturing levels continue to improve, the overall quality of Chinese-made tires rises rapidly, and the quality level of some products is not worse than that of foreign brands.
Tire World Network was informed that at present, the bottleneck in the development of domestic tires is mainly due to weak brand influence.
In contrast, in the past two years, some big-name tires have been plagued by quality problems. In 2016, the most frequently complained tire brand in China due to quality problems was Bridgestone.
Relevant departments have increased the intensity of spot checks on high-risk commodities with frequent quality problems and widespread consumer concerns in recent years.
It is understood that the AQSIQ's spot checks on import and export commodities involve three major categories of electromechanical, textile, resources and chemicals, with a total of 15 key commodities.
The data of the spot checks are mainly from the entry and exit inspection and quarantine institutions of various customs. It conducts spot checks on national ports, domestic markets, cross-border e-commerce, areas of imported products, export-producing enterprises and cargo distribution centers, and covers all major distribution channels for import and export commodities.

LINA Extrusion Pelletizer

Most of the polymer must be kneaded and then granulated before it is made into a final product. Sorted by pelletizing ways, LINA rubber & plastic granulator can be divided into four categories: 1. Hot-cutting and air-cooling pelletizing method. 2. Under-water granulating method. 3. Water-strand extrusion method. 4. Water-ring granulation method. LINA granulator can meet the granulation needs of high-viscosity and low viscosity rubber and plastic materials, as well as some new materials and chemical additives.

LINA Under-water Extrusion Granulator

LINA`s rubber and plastic under-water pelletizing machine is suitable for high-viscosity materials that may easily stick on the rotary cutter and are very sensitive to temperature, such as high viscosity copolymer elastomer (EVA, TPU, TPE, TPR), high viscosity hot melt adhesive and paraffin. This type of is actually similar to die surface hot cutting pelletizing method, the difference is, instead of cool air, there is a steady flow of water through the mold surface and the water directly contact with the die surface. The size of the pelletizing room is such that the blade is free to rotate over the die surface without limiting the water flow. The molten polymer is extruded from the die surface, and the pellets are brought out of the granulation chamber by means of the conditioned water to enter the centrifugal dryer.

Advantage of LINA Pelletizing Line

1. The unit has the whole unit process chain, sound and light failure alarm and fast lock fault point and other control functions. All parts that are in contact with the material are made of stainless steel.

2. High accuracy of temperature control system to ensure the temperature sensitivity of the material.

3. It adopts the drop type separating method after cutting process, to avoid Particle agglomeration and ensure particle cooling.

4. Feeding system of the pressing machine adopts heater and reversing device to solve problem of power outage, material crash and cleaning.

5. Especially, the barrel and die head adopts advanced foreign techniques to ensure and control the dangerous occurred when the pressure is uncontrollable. The honeycomb filter plate is easy to clean and quickly change the mesh and the die head t easy to leak.

6. The hoist adopts automatic return technology to ensure the working efficiency.

7. The technological combination of dual-pull forced feeder and single screw not only meet the high requirement of secondary continuous mixing, but also solve the problem of time and power consuming of traditional working process.
