Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing

[0020] A kind of operation method of glass autoclave is characterized in that: specific operation process is as follows:

[0021] (1) Preheating stage, in which the temperature rises from room temperature to 42-47 degrees;

[0022] (2) The stage of temperature rise and pressure increase. In this stage, the temperature rises from 42°C to 47°C to 77°C to 83°C, and the pressure rises from 0 to 0.60MP to 0.68MP at the same time;

[0023] (3) Pre-balance stage: Under the conditions of pressure 0.60MP~0.68MP and 77℃~83℃, keep it for 10-20 minutes. The function of prebalance is to ensure that the temperature of each point of the PVB film tends to be uniform;

[0024] (4) Pressure holding and heating stage: the pressure is maintained, and the temperature rises from 77 to 83 degrees to 130 to 138 degrees;

[0025] (5) Heat preservation and boosting stage: temperature is maintained,...

Abstract

The invention relates to a glass stilling kettle operating method. The requirement reduction, noise reduction, purchasing cost reduction, production period shortening, energy consumption reduction and worker labor time reduction of a gas source apparatus are realized through the operations of a preheating stage, a heating and boosting stage, a pre-balancing stage, a dwelling heating stage, a heat insulation boosting stage, a step-by-step cooling stage and a gas exhaust stage.

Description

1. Technical field [0001] The invention relates to the technical field of safety glass lamination production, in particular to a pressure-boosting process of a glass autoclave, and in particular to an operating method of a glass autoclave. 2. Background technology [0002] At present, the working pressure of glass autoclaves in the industry is not lower than 1.0 MP. In the past, when users selected air source equipment, they could only choose an air compressor under the condition of 1.25MP, and the pressure boost of the entire glass kettle must reach about 1.25MP. The disadvantages are: first, the cost of procurement is high, second, the gas volume is relatively small, third, the entire pressurization time is long, and fourth, the energy consumption is high. Fifth, workers work longer hours. 3. Contents of the invention [0003] Aiming at the above problems, the present invention invents a method for operating a glass autoclave. The method is of great significance as a n...
