Description
Technical field
The utility model relates to a kind of tubular type rubber detecting device that rubber plastic detects that is used for, and belongs 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, research or Products Development, often need carry out the analysis of composition to the sample of some rubber or plastics.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 using instrument such as gas chromatography or chemical analysis method to confirm that its one-tenth is grouped into then.
For realizing at first must the cracking sample to the analysis of specimen.Because the testing tool Progress in technique, the tester can adopt the cracking appearance of buying to reach the purpose of cracking sample.But the cost of manufacture of cracking appearance is high, and procurement price is expensive, causes detecting the cost height, should not realize.The utility model has designed a kind of simple and practical rubber plastic sample cracker, can be used for general purpose rubber or the heating pyrolyze of plastic sample beyond silica removal, fluororubber and the resin, so that the gas phase analysis after carrying out.Simultaneously the residue that grades of the ash after the cracking can be used for differentiating the gum content of sample, the kind of fill material etc. through analyses such as precision weighings.This instrument simple in structure, make and use with low cost.
The utility model content
Technical scheme:
In order to address the above problem, the utility model has designed a kind of collection sample delivery apparatus, and sample heating arrangement and cracked gas disposal plant are the composition proposal of the tubular type rubber plastic sample cracker of one.
Described tubular type rubber plastic sample cracker, the main body of its apparatus structure is a quartz glass tube with resistance to elevated temperatures, as the carrier that heats under sample to be tested and the oxygen state of isolation.Under the cracking duty, this quartz glass tube places tubular heater to be heated.So quartz glass tube and tubular heater constitute the core component sample heating arrangement of the utility model jointly.
For the quartz boat that sample to be tested will be housed pushes between the heat affected zone of quartz glass tube, or fetching between the heat affected zone after the cracking, and in the propelling movement process, do not injuring the tester and damage instrument, the utility model has designed the sample delivery apparatus.The sample delivery apparatus is made up of the quartz glass bar and the front port end plug of front end with hook.Because quartz glass bar can move along interface cap mesopore is parallel; The tester is through the operation quartz glass bar; Can the quartz boat that sample to be tested is housed that be positioned at heating arrangement quartz glass tube front end 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 under the protection that general purpose rubber beyond silica removal, fluororubber and the resin or plastic sample at high pure nitrogen are carrier gas through the tubular heater heating; The big molecule of rubber in the sample or plastic resin will be cracked into micromolecular gaseous substance, can supply to carry out Gas Chromatography or chemical analysis.Sample is handled the back through cracking residue can occur on quartz boat.These residues also are the samples that carries out subsequent analysis, through precision weighing, in conjunction with the result to the cracked gas gas phase analysis, finally can analyze the amount of the kind of confirming rubber and resin and containing ratio, content of carbon black, ash content, slaine etc.
Because the gaseous substance that cracking produces has pollution to environment,, comprise condensation and absorption and washing so in the time need not analyzing, should carry out necessary disposal to cracked gas to gaseous substance.The utility model has designed the cracked gas disposal plant, adopts three phases to reach the band bottle stopper glass gas bottle of specification in specie, connects successively through 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 through the cracked gas disposal plant and absorbs, and into breadboard ventiduct is arranged in the remaining carrier gas that is cleaned.
Beneficial effect:
The utility model has realized providing for the cracking of rubber plastic sample a kind of purpose of simple cracker; Even if making does not have special-purpose pyrocrack furnace can carry out the general purpose rubber beyond silica removal, fluororubber and the resin or the constituent analysis of plastic sample rubber plastic yet, particularly for qualitative analysis or more suitable to the not too high analysis of the degree of accuracy requirement of analysis result.The used equipment of the utility model all is general chemical test equipment, and for specialized equipment, low price is drawn materials easily, and fabrication and installation are convenient feasible.
Below in conjunction with accompanying drawing the utility model structure is done further explanation.
Description of drawings
Fig. 1: the structural representation of the utility model rubber plastic sample cracker
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 gases washing absorption bottle, 11 carrier gas inlets, 12 carrier gas outlet.
Embodiment
Embodiment: the utility model has the sample delivery apparatus, and sample heating arrangement and cracked gas disposal plant and form are referring to Fig. 1.
The sample delivery apparatus is made up of the 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 considered of quartz pushrod was operated.Because between heat affected zone near quartz glass tube (3), and the sealing property of needs maintenance front ports (4), front port end plug (2) needs processed by heat resistant rubber.A kind of scheme that can adopt is to use fluororubber to make.At the central point of front port end plug (2) circular hole of a perforation end plug is arranged, 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 made up of quartz glass tube (3), tubular heater (6), front port (4) and rear port (5).Quartz glass tube (3) selects for use the thickness of diameter, length and tube wall all to satisfy the needs that carry and heat detected material, and guarantees that the carrier gas circulation is unobstructed.Descend quartz glass tube (3) integral body to penetrate in the tubular heater (6) in working order and accumbency on tubular heater (6), at the middle part of quartz glass tube (3) for receiving 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 is not produced to the influence of cracking with when in time seeing cracking off by oxygen.The two ends of quartz glass tube (3) need wiredrawn edge and sanding to handle, so that front port (4), rear port (5) are installed.Front port (4), rear port (5) are made by pyroceram, are used to seal 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.
