Description

A kind of method of operating of glass autoclave

One. technical field

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

Two. background technology

The operating pressure of glass autoclave in the industry is not lower than 1.0 MP's at present.The user can only select the air compressor under the 1.25MP condition when selecting air machinery in the past, and boosting of whole glass kettle must reach about 1.25MP.Shortcoming is: the one,, the cost of buying is higher, and the 2nd, tolerance is relatively less, and the 3rd, the time of whole pressurization is longer, and the 4th, energy consumption is high.The 5th, the workman is longer 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, good, low-cost, the environment amenable new mechanism of the method combination property and processing method thereof are significant.

The present invention adopts following technical scheme:

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

(1) warm-up phase, this one-phase are that temperature rises to 42 degree～47 degree by room temperature;

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

(3) the pre-equilibration stage: under the condition of pressure 0.60MP～0.68MP and 77 degree～83 degree, kept 10-20 minute, the effect of pre-equilibration is that the temperature that guarantees 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) insulation boost phase: 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 generally is 1.25MP);

(6) equilibrium stage: temperature be 130 the degree～138 the degree and pressure 0.7MP～1.0MP condition under, kept 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 be set between 0～138 degree.Dead time can be set between 0～60 minute.

(8) exhaust phase: be down to the temperature of needs when temperature after, the still internal pressure is discharged;

(9) finish.

Effect of the present invention:

1. the requirement of air machinery reduced, reducing noise, purchase cost reduces.

2. the production cycle shortens, Energy Intensity Reduction, and the workman reduces working time.
