Embodiment 1

[0012] Embodiment 1: 7% bentonite is used as the original soil treatment, first the original soil is dried, and the moisture in the bentonite is removed, and it is standby after being pulverized and sieved to 200 meshes; in the second step, 25% methylbenzene Put high-temperature silicone oil and 12% synthetic hydrocarbon oil into the refining kettle, stir and mix, and add 5% silica sol and 6% molybdenum disulfide at the same time;

[0013] The third step is to prepare 7% carbon black and 7% bentonite in the batching tank, mix them into the kettle, and raise the temperature to 100°C-110°C. The speed of stirring is divided into minutes; the fourth step is to put 29% graphite powder, 5% titanium bronze and 4% high-temperature thickener into the refining kettle, and stop heating when the temperature rises to 200°C-250°C, and take samples from the kettle Measure the consistency and adjust it to the specified range; the fifth step is to cool the contents of the refined kettle to 150...

Embodiment 2

[0014] Embodiment 2: 6% bentonite is used as the original soil treatment, first the original soil is dried, and the moisture in the bentonite is removed, and it is standby after being pulverized and sieved to 200 meshes; in the second step, 20% methylbenzene Put high-temperature silicone oil and 15% synthetic hydrocarbon oil into the refining kettle, stir and mix, and add 3% silica sol and 5% molybdenum disulfide at the same time;

[0015] The third step is to prepare 10% carbon black and 6% bentonite in the batching tank, mix them into the kettle, and raise the temperature to 100°C - 110°C. The temperature rise should be slow, the time is 4-5 hours, at 45 rpm Stir at the speed of 1 minute; the fourth step, put 32% graphite powder, 6% titanium bronze and 3% high-temperature thickener into the refining kettle, and stop heating when the temperature rises to 200°C-250°C, and take samples from the kettle Measure the consistency and adjust it to the specified range; the fifth step ...

Abstract

The invention discloses high temperature leaking stoppage sealing cream. The high temperature leaking stoppage sealing cream comprises the following raw material components by weight percent: 25-35% of graphite powder, 20-28% of methyl phenyl high temperature silicone oil, 10-15% of synthetic hydrocarbon oil, 4-7% of titanium bronze, 3-8% of silica sol, 5-10% of carbon black, 6-9% of bentonite, 5-8% of molybdenum disulfide and 3-5% of high temperature thickening agent. The high temperature leaking stoppage sealing cream has good high temperature performance and good pressure resistance, wear resistance and lubricating property, is durable, can realize no gas leakage under the high temperature condition and is safe, environment-friendly, economic, practical, low in cost and easy to use.

Description

technical field [0001] The invention relates to a high-temperature plugging and sealing ointment. Background technique [0002] Most of the horizontal rotary cracking reactors are used to process black and white solid waste. The cracked gas is exhausted from the central gas outlet at one end of the horizontal rotary reactor and enters the w-shaped baffle chamber. The diameter of the horizontal rotary cracking reactor is generally between 2.2-3m. , supported by rollers. The concentricity of the gas outlet is very poor, especially in the case of dynamic and hot operation, the amount of beating is large, it is difficult to achieve the effect of sealing the gas, resulting in poor sealing, gas leakage and diffusion, seriously affecting the health of workers and the surrounding environment, and Leakage of high-temperature flammable gas mixed with air is prone to fire and serious pollution. Contents of the invention [0003] The technical problem to be solved by the present inv...
