Abstract
The invention discloses a kind of inorganic quartzite slate maintaining process, comprising the following steps: (1) rests the stage: inorganic quartzite slate places inorganic quartzite slate at least 12 hours in the natural environment before steam curing starts after vacuum is suppressed；(2) temperature rise period: after resting, being warming up to 40 degrees Celsius for environment temperature by steam, is kept for 2 hours, is then being warming up to 60 degrees Celsius and is being kept for two hours, environment temperature is finally being warming up to 80 degrees Celsius from 60 degrees Celsius；(3) the constant temperature stage: inorganic quartzite slate being placed in 80 degrees Celsius of environment, and controls humidity between 85 ~ 95%, and constant temperature is kept for 4 hours；(4) temperature-fall period: after constant temperature, by environment temperature from 80 degrees Celsius of slow coolings to room temperature.Strict control heating of the present invention and ramp rate in temperature-fall period, make inorganic quartzite slate have certain structural strength, and the quality of final inorganic quartzite slate obtained is made to be significantly improved.
Description
Technical field
The present invention relates to a kind of inorganic quartzite slate maintaining process, are applied to quartzite slate processing technique field.
Background technique
With social high speed development, people's living standard is gradually increased, and people gradually advocate low-carbon, environmental protection, the life of green
Living, quartzite slate is gradually entered among the family of people, is given birth in the market due to meeting circular economy and energy conservation and environmental protection demand
The producer for producing quartz is more and more, and inorganic quartzite slate has hardness height, texture compared with the organic quartzite slate of tradition
Well, it the advantages that good weatherability, in inorganic quartzite slate process, needs to conserve inorganic quartzite slate, but
It is not directed to the maintaining process of inorganic quartzite slate currently on the market, is usually used in supporting for organic quartzite slate in the market
Shield step is not suitable for inorganic quartzite slate, and the quality of maintaining process directly affects the quality of final products, therefore has
Necessity proposes a kind of maintaining process for being directed to inorganic quartzite slate.
Summary of the invention
In view of the above technical problems, the invention discloses a kind of inorganic quartzite slate maintaining process, strict control maintenances
Heating-cooling rate and thermostat temperature in the process can effectively prevent plate to generate crack, influence final product quality.
The invention discloses a kind of inorganic quartzite slate maintaining process, comprising the following steps:
(1) rest the stage: inorganic quartzite slate is after vacuum is suppressed, by inorganic quartz before steam curing starts
Plate is placed at least 12 hours in the natural environment；
(2) temperature rise period: after resting, environment temperature is warming up to 40 degrees Celsius by steam, is kept for 2 hours, is then existed
It is warming up to 60 degrees Celsius and is kept for two hours, environment temperature is finally being warming up to 80 degrees Celsius from 60 degrees Celsius；
(3) the constant temperature stage: inorganic quartzite slate being placed in 80 degrees Celsius of environment, and control humidity 85 ~ 95% it
Between, constant temperature is kept for 4 hours；
(4) temperature-fall period: after constant temperature, by environment temperature from 80 degrees Celsius of slow coolings to room temperature, rate of temperature fall control
At 20 degrees Celsius per hour.
In above-mentioned steps (2), heating rate is less than 20 degrees Celsius per hour in the temperature rise period.
The beneficial effects of the present invention are: being conserved by above-mentioned curing step to inorganic quartzite slate, strict control
Heating and ramp rate in temperature-fall period, effectively prevent inorganic quartzite slate in temperature-rise period due to volume expansion occurs
It destroys, makes inorganic quartzite slate that there is certain structural strength, make the quality of final inorganic quartzite slate obtained
It is significantly improved.
Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, tie below
Specific embodiment is closed, the present invention is further explained.
The invention discloses a kind of inorganic quartzite slate maintaining process, comprising the following steps:
(1) rest the stage: inorganic quartzite slate is after vacuum is suppressed, by inorganic quartz before steam curing starts
Plate is placed at least 12 hours in the natural environment；
(2) temperature rise period: after resting, environment temperature is warming up to 40 degrees Celsius by steam, is kept for 2 hours, is then existed
It is warming up to 60 degrees Celsius and is kept for two hours, environment temperature is finally being warming up to 80 degrees Celsius from 60 degrees Celsius；
(3) the constant temperature stage: inorganic quartzite slate being placed in 80 degrees Celsius of environment, and control humidity 85 ~ 95% it
Between, constant temperature is kept for 4 hours；
(4) temperature-fall period: after constant temperature, by environment temperature from 80 degrees Celsius of slow coolings to room temperature, rate of temperature fall control
At 20 degrees Celsius per hour.
In above-mentioned steps (2), heating rate is less than 20 degrees Celsius per hour in the temperature rise period.
Steam in the application in temperature-rise period is made by boiler, and the temperature detection in each step can pass through temperature sensor
Detection.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
For personnel it should be appreciated that the present invention is not limited to the above embodiments, described in the above embodiment and specification is only the present invention
Preference, be not intended to limit the invention, without departing from the spirit and scope of the present invention, the present invention also has various
Changes and improvements, these changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by institute
Attached claims and its equivalent thereof.
