The present invention can use three kinds of complete inconsistent emulsions or additive in the process of producing glass fibre air filter paper, has created condition for manufacturing specific glass fiber air filter paper.
Description
Technical field
The invention belongs to glass fiber filter paper and manufacture field, relate to a kind of manufacture method and special painting of glass fibre air filter paperCloth size applicator.
Background technology
In glass fibre air filter paper manufacture process, need to add sizing material to play the effect that strengthens moulding, in classical production processGenerally adopt the method for spraying that sizing material (being generally each specific emulsion) is sprayed on preformed glass fibre l Water Paper,After dry, obtain filter paper finished product. But this method has strict restriction to the kind of institute's glue spraying material, if desired adds other emulsionOr auxiliary agent, just must consider the various emulsions of interpolation or the compatibility of auxiliary agent, so just limit the use of emulsion or auxiliary agent. CauseThis, the prepared glass fibre air filter paper of conventional method only contains a kind of sizing material conventionally at present, cannot meet the need of market.
In view of this, be necessary to provide a kind of manufacture method of new manufacture glass fibre air filter paper, adopt the method madeGlass fibre air filter paper can contain multiple performance difference compared with large sizing material and performance without obvious decline.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of new method of manufacturing glass fibre air filter paper, the method makesGlass fibre air filter paper can contain the bonding sizing material that multiple performance difference is larger. The present invention also provides a kind of and is manufacturing glassIn fiber air filter paper process for being coated with the device of applying glue.
For achieving the above object, the invention provides following technical scheme:

As the manufacture method of glass fibre air filter paper of the present invention further preferably, adopt vacuum bothrium to take off l Water PaperWater, dehydration gained moisture and sizing material recycle.
In the manufacture method of glass fibre air filter paper of the present invention, dehydration gained moisture and sizing material are stored under vacuum bothriumIn the container of face, recycle, cost-saving, reduce the pollution that discharge brings.
As the manufacture method of glass fibre air filter paper of the present invention further preferably, described coating applying glue step is entered in two stepsOK, first to the applying glue of filter recto, and then filter paper reverse side is carried out to applying glue.
As the manufacture method of glass fibre air filter paper of the present invention further preferably, spraying applying glue, the applying glue of filter rectoWith filter paper reverse side applying glue time institute applying glue material be xenogenesis sizing material.
In the manufacture method of glass fibre air filter paper of the present invention, the l Water Paper after spraying applying glue is coated with applying glue through the laggard row of super-dry,The sizing material spraying due to glue spraying step is drying and crosslinked, current cloth of coating-type applying glue can use with glue spraying step sizing material used notCompatible sizing material or auxiliary agent; Be divided into true reverse side and carry out for twice because the present invention is coated with applying glue again, the sizing material of this twice coating is owing to havingThe sizing material isolation that spraying is dried, can be also two kinds of inconsistent sizing materials, so just can use three kinds of complete inconsistent breasts simultaneouslyLiquid or auxiliary agent, for the glass fibre air filter paper of manufacturing property has been created condition.
For the manufacture of a coating size applicator for glass fibre air filter paper, comprise conveyer belt, transfer roller I, size applicatorI, transfer roller II and size applicator II, described transfer roller I, size applicator I, transfer roller II and size applicator II are along conveyer beltMoving direction sets gradually, and described size applicator I and size applicator II are positioned at conveyer belt both sides.
As the present invention be coated with size applicator preferably, it is characterized in that: described size applicator I, II comprise for splendid attire sizing materialContainer and sizing material applicator roll, described sizing material applicator roll outer circumference surface contacts with the sizing material in container with conveyer belt simultaneously.
The another kind that is coated with size applicator as the present invention is preferred, and described conveyer belt is S-type, and transfer roller I and transfer roller II are respectivelyWith S type conveyer belt inscribe, described size applicator I is between transfer roller I and transfer roller II, and described size applicator II is positioned at biographyAfter sending roller II.
The present invention is coated with size applicator can carry out two sides spraying applying glue to glass fibre air filter paper fast, can significantly improve lifeProduce the efficiency of glass fibre air filter paper. The present invention be coated with size applicator also have advantages of occupation of land less, save sizing material.
