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 .

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 % .

vegetable oil plant in two oil technology

Pressed oil is separated by mechanical pressure to allow oil from oil , and extrusion. This method is natural pollution is authentic head and said virgin oils , maintaining the oil is rich vegetable oil plant E ( antioxidant , aging ) , lecithin , unsaturated fatty acids and various nutrients , authentic, oil high product concentration , wall over time , usage of only 1 /2 of the ordinary oil , to " eat oil , eat oil" health purposes fundamentally reflects green, natural , nutrition, health. " China Business" June 24, 2002 edition 14 newspaper reports : to ensure a high nutrient content of edible oil crushing process will be popular !

Leaching rule is the 6th light gasoline and chemical solvents such as benzene , canning soaked , volatile extraction , this method destroys the nutrients oilseeds , taste is not good , refined seed oil extraction toxic to humans is difficult to remove residual solvent and clean , a chemical system oil process, this production process handling capacity, low cost, profitable , mostly domestic vegetable oil plants are using this technology .

Press the daily maintenance of the three elements

Used the press knows, oil press also has low and peak seasons, during the peak season, the use of press time is relatively long, relatively high frequency. Wear this time press is more serious, in order to prolong the service life of press, in the off-season when they need to do maintenance work.

1, the details determine success or failure

For some voids press to detailed examination, especially the gap between the screws haft and a doughnut, must ensure that the spacing in the normal range, when the middle blocked with debris, need timely, prevent the occurrence of jam event. Also check the bolts and nuts tightness, prevent in the use process because of the vibration loosening.

2, pay attention to the waterproof

The off-season is rarely used in the press, for placing time must be far away from water, prevent oil press oxidation rust. In the storage should be to prevent decay,must will excess oil expeller internal cleaning, to prevent residual impurities cause corrosion of oil press. In some bearing part daub lubricating oil, can prevent rust.

3, regular inspection

Although the off-season rarely use press, but in order to ensure the performance,need to regularly restart oil equipment equipment, can effectively prevent some rusting parts, effect of press flexibility. The need for maintenance of the circuit device, to prevent the cable during storage was a rat bite bad.

Mainly in crude oil import quota

In principle, state , private enterprises can apply for crude oil import quotas . However, the actual operation shows that crude oil import quota mainly in the oil, Sinopec and CNOOC allocated between local refineries and private oil enterprises were given quotas very difficult.
This reporter has learned ,  oil equipments  audit and quota management on the grounds that an increase in the international oil market, China 's right to speak, does not cause the blind bidding competition among enterprises , avoiding crude oil into less demanding energy saving small refinery .
But it also caused another phenomenon,  pellet machines  oil imports through state trading and non- state trading of control , the three major oil firms firmly grasp the domestic oil market.
