Insufficient pressure pump overhaul

No oil pump overhaul, if they are dirt clogged oil filter, oil filter should be washable. The case of the oil used for too long, because the sediment adhering to the inlet valve on the The resulting valve does not close together, should be replaced with a new release of oil or old  oil expeller  and clean the inlet valve. If an insufficient amount of oil in the tank, add enough oil to the tank can be,If the vacuum pump in the minors, you can pull out the small piston, and then injected into the oil pressure.
Inadequate maintenance of pump pressure, if there is dirt or poor sealing valve, be washable after grinding, so close together. If an inlet valve plug and oil press Seat poor contact can also be washable after grinding, so close together. If an oil press oil out of the valve plug and seat causing poor contact or tighten oil spills, Progress can grind oil press  oil equipment  plug and seat, so close together or tighten the plug. The case of the small piston and pump wear after the gap is too large, should be replaced with new pumps.

EPDM international supply in short supply

Specializing in thermoplastic vulcanizate (TPV), the high-speed rail industry, has won orders have to be stable with quality and competitive price. At present, because oil prices are high , EPDM international supply in short supply , causing the price of EPDM is almost close to 50,000 yuan per ton / ton , and the traders are confident that exceeded 50,000 yuan / ton, is at hand, so are determined not shipments.
How to deal with  oil expeller  problems in the previous news to talk about co- create the world's leading dynamic vulcanization technology, in the process, greatly reducing the cost of production of TPV . The cost of the raw materials to solve this problem , while the EPDM in particular under conditions of dynamic vulcanization TPV TPV can be kept consistent with previous performance. Currently used in the injection molding industry , has been  oil refinery  without any obstacles , and now in order to further the two sides in terms of melt fracture do further research to expect extrusion, blow molding areas have
more applications .

Thermoplastic processing methods

1 , good flexibility and resistance to deformation , resistance to environmental aging resistance equivalent to EPDM rubber, while its oil and solvent resistance and universal neoprene.
2 , wide application  oil equipment  range (-60-150 ℃), hardness and wide application (25A-54D), easy to stain the advantages greatly improved product design freedom .
3 , excellent processing performance : Available injection, extrusion and other thermoplastic processing methods , efficient,  oil refinery , without additional equipment, high mobility , small shrinkage .
4, green , recyclable, and reusable six no significant decline in performance , compliance with EU environmental requirements.
5 , light weight ( 0.90-0.97 ) , the appearance of uniform quality , high-grade surface , feel good .

Continuous phase consisting of polypropylene

In a wide range of applications with the traditional rubber material , other TPE elastomers ( including TPR \ SBS, SEBS, TPU , etc. ) materials, such as plastic or PVC materials, the overall performance and overall cost alternatives all have
certain advantages , so as to products  machine for pellets  product innovation , improve value-added products , improve competitiveness provides a new choice.
Is ThermoplasticVulcanizate short, the Chinese name for the dynamically vulcanized thermoplastic elastomer EPDM EPDM dynamically vulcanized or thermoplastic rubber, is highly vulcanized EPDM rubber EPDM particles dispersed in a continuous phase consisting of polypropylene PP thermoplastic polymer
elastomer material. TPV room temperature physical properties and functions similar to thermoset rubber , high temperature performance properties of thermoplastics , can be quickly and economically and easily shape . Dynamically vulcanized EPDM TPV thermoplastic elastomer / rubber  oil refinery  rubber material by dynamically vulcanized EPDM EPDM rubber in less than 2 micron-
size particles dispersed in the plastic matrix of polypropylene PP , the rubber and plastic characteristics of a good the combined together to obtain comprehensive high -performance elastomer material .

Ren Hong Kong TM Flame Retardant TPV drying before processing

Because tough TPV Port TM retardant containing about 30% of the flame retardant , so the process is different conventional TPV , the following aspects are to be noted :
Ren Hong Kong  machine for pellets  TPV drying before processing
To be dried before processing , dry conditions of 100 ° C / 2 hours, dried test is in place , you can view products and articles section apparent , if the apparent roughness and  oil equipment  in a cross section , then need to be further dried. At that time did not run out of flame-retardant TPV, you need to be sealed and stored , or when the next use still need to dry !

Screw with pin

Average processing temperature as not more than 200 ° C, for extrusion processing , if there is a pin screw that kind of thing , the processing temperature needs to be further reduced ! For the hardness of Shore A60-80 flame retardant grade TPV, recommended injection molding temperatures from 170 ° C upwards beginning tune ; Shore A85-90 flame retardant grade TPV, from 180 ° C begin ! Extrusion processing ,  oil expeller  respectively, from 160 ° C and 170 ° C begins.
Flame Retardant TPV relatively more difficult coloring , usually our only should the white and black two kinds , if you need other colors , you need to customize ! But there is a direct customer's  oil refinery  , it can speed up the progress of the color , but pay attention to the following questions : a) do not directly use toner , unless the customer's own re- granulation ; b) Optional masterbatch to PE or PP as the base material , and requires very good flowability and lubricity , c) the amount of added masterbatch generally in the 3-5 % .

Plastics and rubber is no longer a simple

Plastics and rubber is no longer a simple, everyday bottle, film, tires, etc., but more infiltrated into the high-precision.
Tip of products, and  machine for pellets  materials, such as high-precision instrument parts, auto parts, medical.
Therapy devices, and even oil exploration highly difficult job. The rapid development in all walks of life, the plastic.
Rubber increasingly showing its vital importance.
With the national focus on supporting the development of new materials industry, the encouragement of sustainable development policy and its implementation And stringent environmental policies, plastics and rubber in the national economy more and more important role in the development have been Become irreplaceable material. Plastics and rubber application has been involved in automotive, electronics, medical, Household appliances, building materials, packaging, printing,agriculture, water conservancy,  oil expeller  engineering, transportation, transport Lose, cosmetic, food, aerospace, apparel, stationery, furniture, gifts and other fields, And applications in these areas continue to expand. While in some new areas should get more Purposes. Currently plastics processing industry has become the country's largest industry, light industry, China has become the world The largest plastics production and consumption country.
