Description
Technical field
The invention belongs to rubber product processing technology field, and in particular to a kind of rubber extraction device and extracting side
Method.
Background technology
Rubber product is mainly formed by the vulcanization of the materials such as rubber, filler, vulcanizing agent and pigment, due to that can add in these components
The material for adding some to be easily worked rubber, these materials for pharmaceutical rubber, with medicament contact during, hold
It is easy to migrate to come out, cause the compatibility of rubber product unqualified.Therefore, in order to improve the compatibility of rubber and medicine,
The material easily migrated out in rubber product, the method by being extracted in alkali lye, make the cleanliness factor of product higher.
Currently in Chinese market, transfusion has carried out alkali density with pad, but this extracting to pharmaceutical rubber and
Say and do not apply to.The shape of one side pad is into plane, compared with rubber product, very light in weight, and even if alkali lye flowing is not so good,
Also it is less susceptible to produce local concentration difference and overstocks the impression formed, on the other hand transfusion pad, with pharmaceutical rubber
Difference, directly contacted with medicine, therefore on extracting quality and the homogeneity of inherent cleanliness factor, producer is not to close very much
Note, is not also required.And pharmaceutical rubber is different, because directly being contacted with medicine, the homogeneity of its quality is by client
Very big concern, thus be accordingly used in transfusion and be not suitable for pharmaceutical rubber with the extracting tank of pad, make a general survey of domestic market, also
There is no a extracting tank for being used to extract pharmaceutical rubber.
In consideration of it, the inherent cleanliness factor of rubber can be greatly improved really in view of extraction effect, while Japanese market
Medical product largely all carried out alkali density, find that its price is remote by seeking advice from the market of Japanese market extracting tank afterwards
Far above the extracting tank price of the country, many pharmaceutical rubber enterprises are allowed to hang back.
Chinese patent CN102702587A discloses a kind of parenteral solution synthetic polyisoprenes plug and preparation method thereof,
The extraction process of polyisoprene plug is directed to, it is to cause the flowing of alkali lye by the mode of pressure release, but poly-
Smaller (the 0.9-1.1 g/cm of density of isoprene plug3), the buoyancy in alkali lye is big, and polyisoprene plug is disk
Formula is not allowed to be also easy to produce impression, and therefore, the extraction process is only applicable light weight and is not likely to produce the rubber of impression.
Chinese patent CN104307198A discloses a kind of efficient method for extracting of butyl glue gasket of low power consuming, and it is to use
Insulation starts exhaust decompression after 40 minutes, insulating process, which does not have deairing step and is only once depressured, completes extracting work
Make, it is equally that the rubber of sheet is stripped to cannot be easily caused impression, and its be directly added into extracting tank it is pure
Water, extraction temperature then is heated to steam, because pure water needs prolonged heating from normal temperature to extraction temperature, the patent
The efficiency of heating surface is low, is not to improve the effective heating means of extraction efficiency.
