The pressure and flow of nozzle water flow are adjusted by technique requirement, to improve point stripping efficiency of mica and avoid excessive powder
It is broken, obtain radius-thickness ratio big high-quality lodicule and higher pulping rate；
(3) mica flake is further removed in outside slurry by hydraulic classification equipment after hydraulic fracture is slurried and is mixed with portion
Divide big and thick scale, calculus, sand grains, the good slurry after classification is screened again, removes -150 purpose of 120 mesh by screen fractionation
Scale；
(4) it is manufactured paper with pulp by cylinder mould machine with slower speed, paper machine speed is determined with the thickness of mica paper model,
Mica paper is manufactured paper with pulp generally using double net single cylinders or more net single cylinder paper machines, on cylinder mould machine after the dehydration of mica slurry, by fresh cleaning
Miva splitting between existing Van der Waals force and electrostatic attraction, so that miva splitting is mutually overlapped to form page, it is true by drier
Empty dry forming obtains combined mica paper.
Preferably, the silt being attached on mica flake, dust, material end are removed by washing in the step (1), passed through
Flotation removes the sundries such as grass roots, leaf, the rope end mixed in mica flake.
Preferably, in the step (3) by sieve control 8 mesh, 16 mesh, 40 mesh, 60 mesh, 80 mesh, 100 mesh sizes cloud
The ratio of female scale distribution.
Preferably, the dryer temperature of cylinder mould machine is controlled at 90 DEG C hereinafter, temperature is avoided to cross high cloud in the step (4)
Female paper takes off cylinder, blistering, while the too low mica paper of temperature being avoided to glue cylinder.
Preferably, after miva splitting is mutually overlapped to form page in the step (4), a small amount of adhesive is added.
The present invention also provides combined mica paper made from a kind of above-mentioned preparation method.
Compared with prior art, the beneficial effects of the present invention are: the present invention shells broken slurrying, energy by using high pressure moisture
In the case where guaranteeing not destroying natural mica physical property, any surface finish, epigranular and the big mica squama of radius-thickness ratio are obtained
Piece；The grade for not meeting papermaking requirement is rejected by hydraulic classiciation, retains the grade for being suitble to mica papermaking；By being classified process,
The mica powder for meeting papermaking requirement is obtained, and high performance mica paper of manufacturing paper with pulp out, combined mica paper scale obtained is larger, can protect
The chemical composition and crystalline texture of natural mica are held, high temperature resistant, thickness is uniform, and tensile strength is high, the anti-cut general character and permeability
And good permeability, although thus the mica paper for solving prior art preparation have the characteristics that it is slightly high, there are the anti-cut general character,
The defect of permeability and poor air permeability, thus the problem of influencing mica paper quality.
