Description

A kind of method of operating of glass autoclave

One. technical field

The present invention relates to safety glass doubling production technical field, especially the boosting technique of glass autoclave, particularly a kind of method of operating of glass autoclave.

Two. background technology

The operating pressure of glass autoclave in current industry, lower than 1.0 MP's.User was when selecting air machinery in the past, can only select the air compressor under 1.25MP condition, and the boosting of whole glass kettle must reach about 1.25MP.Shortcoming is: one is, the cost of buying is higher, and two is that tolerance is relatively less, and three is that time of whole pressurization is longer, and four is that energy consumption is high.Five is that workman is longer for working time.

Three. summary of the invention

The present invention be directed to above problem, invent a kind of method of operating of glass autoclave, the method combination property is good, low cost, environment amenable new mechanism and processing method thereof be significant.

The present invention adopts following technical scheme:

A method of operating for glass autoclave, is characterized in that: concrete operations flow process is as follows:

(1) warm-up phase, this one-phase is that temperature from ambient rises to 42 degree ~ 47 degree;

(2) the increasing temperature and pressure stage, this one-phase is that temperature rises to 77 degree ~ 83 degree by 42 degree ~ 47 degree, pressure simultaneously by 0 voltage rise to 0.60MP ~ 0.68MP;

(3) in the pre-equilibration stage: under the condition of pressure 0.60MP ~ 0.68MP and 77 degree ~ 83 degree, keep 10-20 minute, the effect of pre-equilibration ensures that the temperature of PVB glued membrane each point is tending towards even;

(4) the pressurize temperature rise period: pressure keeps, and temperature rises to 130 degree ~ 138 degree by 77 degree ~ 83 degree;

(5) boost phase is incubated: temperature keeps, pressure is raised to 0.7MP ~ 1.0MP by 0.60MP ~ 0.68MP, the maximum pressure of current pressurization is less than or equal to 1.0MP, is the key point of whole technique, has broken traditional pressing technology (conventional press technique is generally 1.25MP);

(6) equilibrium stage: under temperature is 130 degree ~ 138 degree and pressure 0.7MP ~ 1.0MP condition, keeps 30-60 minute;

(7) temperature-fall period step by step: temperature is down to normal temperature by 130 degree ~ 138 degree, is divided into 3 stages, and the temperature in per stage can set between 0 ~ 138 degree.Dead time can set between 0 ~ 60 minute.

(8) exhaust phase: after temperature is down to the temperature of needs, discharges pressure in still;

(9) terminate.

Effect of the present invention:

1. the requirement of pair air machinery reduces, and noise reduces, and purchase cost reduces.

2. the production cycle shortens, and energy consumption reduces, and workman reduces working time.

Four. accompanying drawing explanation

Fig. 1 is the flow chart of the method for operating of a kind of glass autoclave of the present invention.

Five. detailed description of the invention

Below in conjunction with accompanying drawing, the invention will be further described
