The cellulose derivation system by the natural high polymer
cellulose after chemistry modifications and so on the
etherification or esterification as well as passes through the
versatility high polymer fine chemical industry material again
which but the stem grafting makes results in. As soon as the
cellulose derivative distributes four types: Cellulose ester
(nitrocellulose, third acetyl cellulose, viscose cellulose).
Cellulose ether (ion carboxymethyl cellulose and non-ionic
methylcellulose, ethyl cellulose, ethylol cellulose, hydroxy propyl
methylcellulose). Cellulose semi-permeable membrane (for example
cellulose triacetate and two acetyl cellulose mix membrane).
Cellulose derivative stem grafting modification (for example
coherent cellulose and styrene stem grafting modification, styrene
and propylene nitrile mixture and viscose cellulose graft polymer).
The main purpose of product
Cigarette filter tip, vinegar fibrous plastic moulding material,
film, coating, polyreaction, building materials, oil field,
spinning and weaving, food, medicine, electronic component and so
on. The similar type also widely applies in the wood pulp, material
and so on purification cotton and kapok dry.
(1): The turnover material time is advantageous for the adjustment
and the control, guarantees the material moisture content and the
uniformity.
(2): The different sector entered rheumatism to adjust, reduced the
energy consumption and improves the quality of the product.
(3): The equipment flow has regards the mirror and the gate, is
advantageous for the observation and the cleaning up (pneumatic
drier shoe and tornado easy product material, cannot clean up!).
(4): Because uses the low pressure air blower, the use amount of
wind is big, the output easy to guarantee, the dust displacement
small ).
(5): Under the vacuum state for drying, the safety coefficient is
high.
(6): Passes in and out continuously the material, reduces the area
and the pollution.
Passes through many year practices in view of cellulose dry craft
this company, the optimized improvement part production equipment:
The seriation production practice experience supplies the
reference:
For example: The CMC, HPMC, HEC, MC and son on of Cellulose of
mature drying craft.
(1 ): Two level of pneumatic driers.
(2 ): Two level of vibration fluid bed dryer.
(3 ): The level air current and the fluid bed dry combination for
drying.
The modified cellulose dry mature craft, uses the continual vacuum
disc type to be dry.
The HeBei partial users use the vacuum rake type dryly (the main
characteristic: A little batch raid of production, solvent
recovery).
Has a part of cellulose to use the single air current dry or the
flash vaporization dry, the conveyor-type drier, the drying oven
ebullition dry and so on.
