Description

Emulsion polymerization test small-scale polymerization bottle

Technical Field

The utility model relates to a small-scale polymerization bottle for a emulsion polymerization test, and belongs to the technical field of polymerization tests.

Background

The emulsion polymerization test small trial polymerization bottle is mainly used for polymerization tests of styrene butadiene rubber and is used for judging whether raw materials are suitable for SBR polymerization reaction. The polymerization test uses raw materials and chemicals including: butadiene, styrene, complex soaps, t-dodecyl mercaptan, dicumyl hydroperoxide, and the like. The polymeric bottle is made of glass and has a flat bottom. The volume is 870-930ml, the using pressure is 5Kg/cm2, and the feeding amount is 60% of the maximum feeding amount coefficient.

At present, a black rubber gasket is used for a bottle opening of a polymeric bottle, a bottle cover is similar to a beer bottle cover, and three small holes are formed in the bottle cover, so that feeding or sampling is facilitated.

Several polymerization bottles were prepared for the test, and appearance inspection and numbering were performed. And (3) weighing according to the formula, adding deoxidized water, compound soap and TDM/ST, performing nitrogen replacement, covering the gasket and the bottle cover, pressing the bottle cover by using a bottle manual capping machine, pressing the gasket, putting the gasket into a protective cover, performing leak testing, and checking whether a leak exists. Then adding a certain amount of butadiene, putting the mixture on a bottle rack in a groove of a polymerization machine, and performing rotary cooling. During the reaction, the prescribed amounts of DIP, CP-50, CP-2 (P) and TDM (P) were added by syringe through small holes in the bottle cap. In measuring the conversion of the polymerization reaction, the latex in the bottle was withdrawn by a syringe through a small hole in the cap. When terminating the reaction, a prescribed amount of a terminating agent was introduced through a small hole in the cap by a syringe.

The prior art has the problems that in the capping process of the polymeric bottle, firstly, a black rubber gasket is placed on a glass polymeric bottle mouth, and the bottle cap is placed on a capping necking port of a manual capping machine (such as the reference numeral 4 in fig. 1), and the bottle cap can be firmly sucked and downward due to the magnet arranged at the place of the capping machine. But can not be seen from the outside, the bottle cap and the polymerized bottle mouth with the rubber gasket are connected together only by touching the bottle cap, the bottle cap and the bottle mouth are compacted by applying force through the handle of the capping machine, the handle is required to be lifted for a plurality of times, the polymerized bottle is rotated, and then the bottle cap is compacted by pressing. Because black rubber gaskets are resilient, if the gasket is misplaced or otherwise, the gasket is prone to misalignment, and the bottle of polymerization test data will be voided once leaked due to the gasket being subjected to multiple needle sticks and samples. In addition, most importantly, the bottle cap is compacted for a plurality of times, and then the magnet of the capping machine is pressed, so that the bottle cap is tightly connected with the capping shrinkage of the capping machine. The bottle neck is not easy to take down, the place where the bottle neck is close to the bottle neck is required to be tightly clenched by the tiger mouth of a hand, the clenched tiger mouth of the hand is contacted with the necking of the capping machine, the bottle neck is forcefully separated from the necking of the capping machine, the bottle neck is broken from the bottle neck due to uneven hand or long-time use quality reduction of the bottle neck, the bottle is made of glass, and the hand of an operator is easy to be pricked without attention, so that accidents are caused.

With the increase of polymerization tests in recent years, the use of polymerization bottles is more and more frequent, and a bottle cap becomes a bottleneck of bottle polymerization test operation. In the test process, the bottle neck is broken and the material is wasted because the bottle mouth cannot be taken down, so that the test operation is affected normally.

Disclosure of Invention

Only one circle of raised threads is arranged between the original bottle mouth and the bottle neck, the bottle cap is pressed downwards by a handle of a manual capping machine, the lower part of the bottle cap is wrapped in the threads, and the threads are blocked to play a role in sealing. The bottle cap can be tightly and multiply locked with the threaded opening by changing one thread of the bottle opening into a plurality of threads with standard size. The original bottle cap and the beer cap are completely the same in type, disposable, easy to deform and difficult to operate. The copper cap is changed into a copper cap with a threaded opening, and three small holes are formed in the copper cap. Thus, the bottle cap can be recycled, and the bottle cap is ensured to be closely matched with the bottle mouth.

Preferably, the height of the bottle cap is larger than 1/2 of the diameter of the bottle cap, so that the threaded contact surface is larger, and the fixing and sealing effects are better.

Preferably, the number of the small holes is three.

The raw polymeric bottle material was glass and its lifetime was five years in the test. In comparison, the material of the polymeric bottle is quartz glass, which has extremely low thermal expansion coefficient, high temperature resistance, extremely good chemical stability and excellent electrical insulation, and can be used for laboratory instruments.

The bottle cap is made of copper, and the rubber gasket is close to the inner diameter of the copper nut, so that the gasket is tightly plugged and is not easy to leak materials.

Because of the material filled in the polymerization bottle, pressure is generated during the polymerization reaction, and the protection cover is additionally arranged on the polymerization bottle. The protective cover is made of stainless steel and is divided into an upper part and a lower part, and the middle part is clamped.

The protective cover consists of a protective cover body at the lower half part and a protective cover at the upper half part.

Further, a plurality of limit pins fixed on the protective cover body are arranged on the peripheral surface of the top of the protective cover body, and a plurality of hollowed-out fixing grooves (shown in fig. 3-5) are arranged on the side wall of the bottom of the protective cover body correspondingly to carry out rotary clamping.
