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 .

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 % .

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.

Vegetable oil purchase skills

1, the smell the smell. Should have the inherent flavor of vegetable oil plant (such as peanut oil, sesame oil, Rapeseed Oil etc.), such as smell may be the acid value, peroxide value exceed the standard products.

2, see the appearance. Products of good quality, high degree of refining of edible vegetable oils should be clarified, transparent, with the variety of unique color, does not contain any impurity.

3, look at the price. Buying time to compare the prices of similar products. Attention should be paid to the product name, list of ingredients, recognition or similar name ormixed with other cheap vegetable oils to mislead consumers.

4, look at the label. Should choose large and famous enterprises to purchase products,label product name, list of ingredients, net content, the implementation of standards,production date, shelf life, factory name, product grades, whether to label GM, storageconditions should be complete.oil press

Bulk small pack edible oil prices

Now the market or changes in the diversity of edible oil , edible oil of different quality in different packaging reflects different , just like a small pack edible oil in bulk cheaper oil press , many consumers tempted endless. However, previous press from quality inspection conducted by the State Bureau of Technical Supervision of edible oil can be found : bulk edible oil quality was worse than the small package edible oil. Bulk easily lead peroxide value of edible oil and oil extraction solvent residue donut maker . Edible oil in the state should not exceed 10 mg peroxide , peroxides seriously overweight will produce large amounts of low molecular weight oils volatiles , such as aldehydes , ketones , such substances on human health is very bad , some of which are also ingredients carcinogenic . Because of these things ever happened , home -based press has constantly appeared , because it feed line us a press clothed yourself , so ah such a machinery company is getting more, but Goodwin machinery the credibility of the press is a very good offer also includes a first-class quality , so experts suggest that as much as possible to buy a small pack edible oil , which not only has a certain quality assurance , but also healthy.
