Abstract
The present invention relates to shaft end sealing material for some industrial rotary equipment, and is especially one kind of PTFE stuffing and its preparation process. The PTFE stuffing consists of graphite 30 wt%, heat resisting lubricating oil 10 wt%, and spreading PTFE belt 60 wt%. The preparation process includes the following steps: crushing spreading PTFE belt into fiber; mixing the materials to form mashed mixture; and packing. The present invention has the advantages of high sealing performance, easy filling, high temperature and high pressure resistance, capacity of prolonging the service life of the equipment and other features.
Description
Technical field
The invention belongs to chemical technology field, relate to a kind of industrial rotating equipment and reciprocal equipment of part of being used for, as the shaft end seal material of water pump, valve, particularly a kind of tetrafluoroethylene weighting material and preparation method thereof.
Background technology
At present, domestic industrial rotating equipment and the reciprocal equipment of part of being used for, as the shaft end seal material of water pump, valve, tradition adopts asbestos packing to do charges and seals.This compaction material exists: axle is easy to wear with axle sleeve, short weak effect of sealing time, reduced equipment work-ing life, need defective such as shutdown maintenance.
Summary of the invention
The present invention has overcome the defective of above-mentioned existence, and purpose is for industrial rotating equipment and the reciprocal equipment of part, as the shaft end seal of water pump, valve, provides a kind of tetrafluoroethylene weighting material and preparation method thereof.
A kind of tetrafluoroethylene weighting material of the present invention and preparation method thereof content Description:
A kind of tetrafluoroethylene weighting material of the present invention and preparation method thereof is characterized in that: the tetrafluoroethylene weighting material is made every effort to overcome lubricating oil 10% and tetrafluoroethylene extended band 60% is formed by: Graphite Powder 99 30%, high temperature resistant rubbing;
The preparation method of tetrafluoroethylene weighting material, it comprises the following steps:
(1), with the fragmentation of tetrafluoroethylene extended band, be fibrous;
(2), by proportion of raw materials get Graphite Powder 99 30%, high temperature resistant rubbing is fibrous tetrafluoroethylene extended band 60% after making every effort to overcome lubricating oil 10%, fragmentation, sends in the stirrer to stir, and forms the mixture of mud shape;
(3), check, packing, warehouse-in.
The present invention is a kind of industrial rotating equipment and reciprocal equipment of part of being used for, shaft end seal material as water pump, valve, have good seal performance, filling easy, can online reparation exempt to change packing, high temperature resistant, high pressure, the axle sleeve that do not wear and tear, can prolong equipment life, simple installation, save energy, cut down the consumption of energy, do not have the environment friendly and pollution-free characteristics of revealing, and convenient the storage and transportation.
Embodiment
A kind of tetrafluoroethylene weighting material of the present invention and preparation method thereof be achieved in that the tetrafluoroethylene weighting material by: Graphite Powder 99 30%, high temperature resistant rub make every effort to overcome lubricating oil 10%, tetrafluoroethylene extended band 60% is formed.That produces 100kg can pouring-in filler packing, and can get by proportion of raw materials: Graphite Powder 99 30kg, high temperature resistant rubbing are made every effort to overcome lubricating oil 10kg, tetrafluoroethylene extended band 60kg.With the fragmentation of tetrafluoroethylene extended band, be fibrous, above-mentioned raw materials is sent in the stirrer to stir to reach fully in 45 minutes to mix, the mixture that forms the mud shape is made the tetrafluoroethylene weighting material, tests, packs, puts in storage.
The present invention is a kind of sealing prod that is mixed and made into by Graphite Powder 99, toxicological harmless synthon, high temperature resistant luboil, during use with industrial rotating equipment such as water pump, valve open, with original sealing material full scale clearance, mixing with the mud shape can be filled in the packing cavity of equipment by pouring-in filler packing equably, very easy to use, can onlinely repair.The leakage that takes place when apparatus for sealing of the present invention is worked is almost nil, and tetrafluoroethylene weighting material operation back AUTOMATIC ZONING, the interfacial friction coefficient is extremely low, can reduce consumption, environment friendly and pollution-free, can effectively prevent axle and the wearing and tearing of axle sleeve, prolongation equipment life.
Claims (1)
1, a kind of tetrafluoroethylene weighting material is characterized in that: the tetrafluoroethylene weighting material is made every effort to overcome lubricating oil 10% and tetrafluoroethylene extended band 60% is formed by: Graphite Powder 99 30%, high temperature resistant rubbing; Its preparation method comprises the following steps:
(1), with the fragmentation of tetrafluoroethylene extended band, be fibrous;
(2), by proportion of raw materials get Graphite Powder 99 30%, high temperature resistant rubbing is fibrous tetrafluoroethylene extended band 60% after making every effort to overcome lubricating oil 10%, fragmentation, sends in the stirrer to stir, and forms the mixture of mud shape;
(3), check, packing, warehouse-in.
