After Jun Yun, carry out pre-crystallized, dried, heating fusion plastification and slab process successively, generate insulation sheet, by described polyester
Sheet biaxial tension, ultimately generates insulation film.
The prepolymer that Prepolycondensating reactor reaction generates is respectively through melt Sleeve three-way valve discharging, prepolymer discharging pump supercharging
After collecting with melt Sleeve three-way valve afterwards, through prepolymer filter, more specially designed melt jacket pipe is delivered to final minification and is gathered
In reactor.
Precondensation material is continuously fed into final polycondensation reactor, just can arrive final products under stirring and high vacuum condition
Quality.Control pressure, temperature and the time of staying to proper level so that the viscosity measured as the degree of polymerization is adjustable.By regulation
The temperature of heating agent, can regulate temperature of charge in reactor, controls the intrinsic viscosity of outlet material.Being passed through nitrogen, output PET is altogether
Polyester slice.
By described copolyester section and polyester masterbatch mix homogeneously by a certain percentage, containing titanium dioxide in described polyester masterbatch
Silicon and Kaolin, and the compound of PET copolyester section and polyester masterbatch is carried out pre-crystallized and dried, carry out two-way
Before stretching, must first carry out pre-crystallized and dried.The purpose of do so is: improve polymer softening point, it is to avoid its
The mutual adhesion of resin particle or caking during being dried and melt extruding；Remove the moisture in resin, prevent gathering containing ester group
Hydrolysis is there is or produces bubble in compound during melt extruding.
Pre-crystallized and the drying equipment of PET typically uses with crystallizing bed packed column, is furnished with dry air preparation dress simultaneously
Put, including air compressor machine, molecular sieve moisture separator, heater etc..Pre-crystallized and baking temperature is 150 DEG C～170 DEG C, and drying time is about
3～4h, dried PET section moisture content requires to control 30～50ppm.
PET section after crystallization and dried enters single screw extrusion machine and carries out heating fusion plastification.In order to protect
The card PET good plasticizing quality of section and stable melt extrusion pressure, the structure design of screw rod is extremely important.Except to major diameter
Outside ratio, compression ratio, each functional section all there are certain requirements, also special requirement are Barrier type screw rods, and the screw rod of this structure is favourable
In ensureing the good plasticizing of extruded material, the stable discharging of the uniformity of outlet of extruder temperature of charge, extruder and well
Aerofluxus, and be conducive to improving plasticating capacity.
If extrusion capacity is not the biggest, it is recommended that select vented twin-screw extruder.This extruder have two air vents with
Two pumped vacuum systems are connected, and have good exhaust, dehumidification function, can moisture contained in material and oligomer be taken out
Walk, thus the pre-crystallized/drying system of a set of complexity can be saved, reduce investment outlay and reduce operating cost.Extruder temperature sets
Determine from charge door to head, be about 210 DEG C～280 DEG C.
Melt-stoichiometry is realized by high-precision gear pump.The effect of dosing pump is to ensure that to melting that die head provides
Body has enough and stable pressure, to overcome resistance when melt passes through filter, keeps the uniformity of film thickness.Melt
Dosing pump generally uses two oblique gears, and the heating and temperature control of pump is at 270 DEG C～280 DEG C.
The heating-up temperature of described heating fusion plastification is 275 DEG C～285 DEG C, that may be present miscellaneous in order to remove in melt
The foreign bodies such as matter, gel particles, flake, often one filter of each installation, filter heating before and after dosing pump on melt pipeline
Temperature controls at 275 DEG C～285 DEG C.
The effect of melt pipe is to couple together, extruder, dosing pump, filter etc. to allow melt therefrom lead to die head
Cross.Melt pipe inwall requires the brightest and the cleanest and without dead angle, and the length that melt pipe is concatenated is the most shorter, in order to avoid melt is at it
Middle viscous flow, the time of staying is long and produces degraded.
After being squeezed into melt pipe from the melt of extruder, flow separately through coarse filter, dosing pump, fine filter laggard
Enter die head.If three-layer co-extruded production line, above die head, also configure that a melt distributor.Filter, dosing pump and molten
Body pipe etc. can use electrical heating, it is also possible to conduction oil chuck heats.Melt pipe heating and temperature control is at 275 DEG C～285 DEG C.
The longitudinal direction being heated to carry out under elastomeric state certain multiple in longitudinal stretching unit by the sheet from slab machine is drawn
Stretch.Longitudinal stretching machine by pre-hot-rolling, draw roll, chill roll, jockey pulley and rubber roller, infrared heating pipe, heating unit and
Driving means etc. form.Longitudinal stretching is usually single-point stretching, also has multiple spot to stretch, such as 2 or 3 stretchings.Vertical Lapie is
Produced, generally 3～4 times by the speed difference between pull-down roller and fast withdrawing roll.
Transverse drawing mill is by baking oven, chain folder and guide rail, plenum chamber, chain tensioning device, guide rail width adjusting means, opening and closing folder
Device, hot air circulating system, lubricating system and EPC etc. form.Its effect is to be divided in transverse stretching machine by the thin film through longitudinal stretching
Do not complete the cross directional stretch of thin film by preheating, tentering, thermal finalization and cooling.Horizontal Lapie is 3～4 times.
Insulation film shrinkage factor under high temperature steam environments that this case prepares is little, maintains original form and performance；With
Time vapour transmission rate under high steam environment little, serve damp proof function, it is ensured that the insulating properties of insulation film are not subject to
