The Storage Environment Of The Rubber Bending Roller Is The Same As That Of The Blanket

According to the scope of application and application, the first method divides rubber into two categories: general rubber and special rubber. The second method divides rubber into three categories: general-purpose rubber, semi-general-purpose rubber, also called special rubber of large variety, and special-purpose rubber, also called special rubber of small variety.

According to the presence or absence of double bonds in the molecular chain of rubber, it is divided into two categories: unsaturated rubber and saturated rubber. Due to the double bonds in the molecular chain, unsaturated rubber generally has high chemical activity and is easy to react with vulcanizing agents. The vulcanization rate is fast, but It is also easy to react with oxygen, ozone, etc., has poor aging resistance and low use temperature; at the same time, due to the isolation of double bonds, the molecular mobility is high, the elasticity is high, and the cold resistance is good.

Rubber can also be divided into strong self-repairing rubber and weak self-repairing rubber. The former is also called crystalline rubber (such as natural rubber, neoprene), and the latter can be divided into microcrystalline rubber (such as butyl rubber). And amorphous rubber (such as styrene-butadiene rubber, etc.).

The rubber roller shaft head and bearing should be kept well lubricated. We know that the accuracy of the rubber roller shaft head and bearing directly affects the effect of ink transfer and ink distribution. If the rubber roller shaft head, bearing wear and clearance are caused by poor lubrication, printing ink will inevitably result.

The ills of unevenness. At the same time, printing rod marks can also be caused by bad conditions such as glue jump and slip glue. Therefore, you should regularly fill the rubber roller shaft head and bearings with lubricant to prevent the machine from wearing the rubber roller during normal use and ensure printing quality.

The rubber bending rollers are used for too long, and the erosion of chemicals causes the "slag" of rotten rubber. Do not use such rubber rollers, otherwise it will seriously affect the print quality.

In order to ensure that it does not affect production and printing quality, there must be spare ink rollers, but do not store too much to avoid aging. The storage environment of the rubber roller is the same as that of the blanket. In addition, the rubber rollers should be set up straight at the journal and the surfaces should not touch each other.

Resistance to media: This coefficient is very important: some rubber rollers need to be used under immersion conditions, so you should first understand what kind of media they are used in before formula design, acid resistance, alkali resistance, high temperature resistance, corrosion resistance, resistance Abrasion, the superior properties of various rubbers are very particular about the raw materials and formula of the rubber.
