Special single-component jointing and gap filling silicon rubber for curing EMAS at room temperature and preparation method of special single-component jointing and gap filling silicon rubber

The invention discloses special single-component jointing and gap filling silicon rubber for curing EMAS at room temperature and a preparation method of the special single-component jointing and gap filling silicon rubber. Low-viscosity alpha, omega-dihydroxy-polydimethylsiloxane is used as base rubber, linear polydimethylsiloxane is used as an additive, the hydroxyl content is increased, a fumed silica is adopted for reinforcing, a mixture of aluminum hydroxide and melamine cyanurate is used as flame-resistant filler, methyltris(methylethylketoxime)silane and tri(2-butaneneoxime)cinylsilane are used as crosslinking agents, aminopropyltriethoxysilane and gamma-methacryloxypropyltrimethoxysilane are used as adhesives, a production process is controlled, and then, the special single-component jointing and gap filling silicon rubber for curing EMAS at room temperature, which is good in flowability, capable of rapidly curing, good in flame retardance, moderate in strength and good in adhesive ...

Drill hole splitting mechanism driving method

The invention provides a drilling splitting mechanism driving method, and particularly relates to the technical field of engineering construction and mining. The driving method of the drilling and splitting mechanism comprises the following steps that the drilling mechanism longitudinally reciprocates to drill holes; the telescopic mechanism drives the drilling mechanism to translate from a first position to a second position, and the splitting mechanism translates from a third position to the first position; and the splitting mechanism is used for splitting the rock drilling holes. Different from the prior art, according to the technical scheme, drilling is conducted through the drilling mechanism, the telescopic driving mechanism drives the splitting mechanism and the drilling mechanism to move, the splitting mechanism is automatically aligned and inserted into the rock drilling hole, the splitting mechanism does not need to be manually aligned with the rock drilling hole, and the construction ...

Medicine for treatment of epilepsy

A medicine for curing epilepsy with total effective rate up to 95% and less by-effect is prepared from 18 Chinese-medicinal materials such as scorpion, centipede, gastrodia tuber, arisaema tuber, curcuma root, etc. through immersing in wine, baking or drying in air, proportional mixing, sterilization and making wasty pill.

Drilling and splitting mechanism and all-in-one machine

The invention provides a drilling and splitting mechanism and a drilling and splitting all-in-one machine. The drilling and splitting mechanism comprises a drilling mechanism, a splitting mechanism and a telescopic mechanism. The telescopic mechanism comprises a telescopic oil cylinder and a first connecting arm, and the telescopic oil cylinder is used for driving the first connecting arm to move; the drilling mechanism and the splitting mechanism are located on the same side of the telescopic mechanism, and the first connecting arm is connected with the splitting mechanism and drives the splitting mechanism and the drilling mechanism to move; the telescopic displacement of the telescopic oil cylinder is the distance between the rock drill and the splitting device, so that the splitting mechanism can move to the position of the original drilling mechanism when the telescopic oil cylinder stretches out or retracts. Different from the prior art, according to the technical scheme, splitting ...
