Description
Technical field
The present invention relates to a kind of pipe type rubber detecting device for the rubber plastic detection, belong to rubber, plastic chemistry analysis and detecting instrument technical field.
Technical background
Rubber and plastic products have spread to daily life and production field.For collect evidence, the exploitation of research or product, often need to carry out for the sample of some rubber or plastics the analysis of composition.A kind of effective method is exactly that the sample that needs are tested is heated under the condition of starvation, rubber in the sample and resin and other organic principle are cracked into gas, are then using the instrument such as gas chromatography or chemical analysis method to determine that its one-tenth is grouped into.
For realizing at first must the cracking sample to the analysis of specimen.Because the progress of testing tool technology, the tester can adopt the cracking instrument of buying to reach the purpose of cracking sample.But the cost of manufacture of cracking instrument is high, and procurement price is expensive, causes testing cost high, should not realize.The present invention has designed a kind of simple and practical rubber plastic sample cracker, can be used for general purpose rubber beyond silica removal, fluororubber and the resin or the heating pyrolyze of plastic sample, so that the gas phase analysis after carrying out.Simultaneously the residue that grades of the ash after the cracking can by analyses such as precision weighings, be used for differentiating the gum content of sample, the kind of fill material etc.This instrument simple in structure, make and use with low cost.
Summary of the invention
Technical scheme:
In order to address the above problem, the present invention has designed a kind of collection sample delivery apparatus, the composition proposal of the pipe type rubber plastic sample cracker that sample heating apparatus and cracked gas disposal plant are integrated.
Described pipe type rubber plastic sample cracker, the main body of its apparatus structure are quartz glass tubes with resistance to elevated temperatures, as the carrier that heats under tested sample and the oxygen state of isolation.Under the cracking duty, this quartz glass tube places tubular heater to be heated.Therefore the common formation of quartz glass tube and tubular heater core component sample heating apparatus of the present invention.
For the quartz boat that tested sample will be housed pushes between the heat affected zone of quartz glass tube, or fetching between the heat affected zone after the cracking, and do not injuring the tester and damage instrument in the propelling movement process, the present invention has designed the sample delivery apparatus.The sample delivery apparatus is comprised of quartz glass bar and the front port end plug of front end with hook.Because quartz glass bar can be along interface cap mesopore parallel, the tester is by the operation quartz glass bar, the quartz boat that tested sample is housed that is positioned at heating arrangement quartz glass tube front end can be pushed into or be pulled away between the heat affected zone of quartz glass tube, realize the purpose of sending sample.
Between the heat affected zone of quartz glass tube, can rise to cracking temperature through the tubular heater heating under the protection that general purpose rubber beyond silica removal, fluororubber and the resin or plastic sample at high pure nitrogen are carrier gas; the large molecule of rubber in the sample or plastic resin will be cracked into micromolecular gaseous substance, can be for carrying out Gas Chromatography or chemical analysis.Sample residue can occur after processing through cracking on quartz boat.These residues also are the samples that carries out subsequent analysis, by precision weighing, and in conjunction with the result to the cracked gas gas phase analysis, finally can the Analysis deterrmination rubber and the amount of the kind of resin and containing ratio, content of carbon black, ash content, slaine etc.
Because the gaseous substance that cracking produces has pollution to environment, so not needing to carry out necessary disposal to cracked gas when gaseous substance analyzed, comprise condensation and absorb and wash.The present invention has designed the cracked gas disposal plant, adopts three phases to reach in specie the band bottle stopper glass gas bottle of specification, connects successively by emulsion tube and double glazing pipe.Form the disposal plant that contains a pyrolysis gas condensate bottle and two pyrolysis gas washing absorption bottles.Cracked gas is condensed after by the cracked gas disposal plant and absorbs, and the ventiduct into the laboratory is arranged in the remaining carrier gas that is cleaned.
Beneficial effect:
The present invention has realized that the cracking for the rubber plastic sample provides a kind of purpose of simple cracker, even if so that there is not special-purpose pyrocrack furnace also can carry out the general purpose rubber beyond silica removal, fluororubber and the resin or the constituent analysis of plastic sample rubber plastic, particularly require not too high analysis more suitable for qualitative analysis or to the degree of accuracy of analysis result.The used equipment of the present invention all is general chemical test equipment, and for specialized equipment, low price is easily drawn materials, and fabrication and installation are convenient feasible.
Below in conjunction with accompanying drawing structure of the present invention is described further.
Description of drawings
Fig. 1: the structural representation of rubber plastic sample cracker of the present invention
Wherein: 1 quartz glass bar, 2 front port end plugs, 3 quartz glass tubes, 4 front ports, 5 rear ports, 6 tubular heaters, 7 pyrolysis gas analysis and Control valve and outlets, 8 pyrolysis gases are disposed operation valve and outlet, 9 pyrolysis gas condensate bottles, 10 pyrolysis gas washing absorption bottles, 11 carrier gas inlets, 12 carrier gas outlet.
Embodiment
Embodiment: the present invention has the sample delivery apparatus, and sample heating apparatus and cracked gas disposal plant and form are referring to Fig. 1.
The sample delivery apparatus is comprised of quartz glass bar (1) and the front port end plug (2) of front end with hook, and front end can reach between the heat affected zone of quartz glass tube (3) when the length of quartz pushrod should be considered to operate.Because between the heat affected zone near quartz glass tube (3), and the sealing property of needs maintenance front ports (4), front port end plug (2) needs be made by heat resistant rubber.A kind of scheme that can adopt is to use fluororubber to make.The circular hole that a perforation end plug is arranged at the central point of front port end plug (2), the diameter of the same quartz glass bar of the internal diameter in hole (1), and can guarantee quartz glass bar (1) parallel pull in the hole of front port end plug (2).
Heating arrangement is comprised of quartz glass tube (3), tubular heater (6), front port (4) and rear port (5).Quartz glass tube (3) selects the thickness of diameter, length and tube wall all to satisfy the needs of carrying and heating detected material, and guarantees that the carrier gas circulation is unobstructed.Descend in working order quartz glass tube (3) integral body to penetrate in the tubular heater (6) and accumbency on tubular heater (6), at the middle part of quartz glass tube (3) for being subjected to heat space.The high pure nitrogen that keeps certain flow in the quartz glass tube (3) is as carrier gas, so that the gaseous substance that the protection style produces when not being subjected to oxygen to the impact of cracking and in time sending cracking.The two ends of quartz glass tube (3) need wiredrawn edge and sanding to process, in order to front port (4), rear port (5) are installed.Front port (4), rear port (5) are made by pyroceram, are used for sealing quartz glass tube (3) and delivery of carrier gas.Wherein the outlet of rear port (5) is the threeway shape, and two ends are separately installed with pyrolysis gas analysis and Control valve and outlet (7) and pyrolysis gas and dispose operation valve and outlet (8) therein.
