Before operation, instrument need be energized one hour, ensures the preheating time of balance 19, ensures precision.And ensure that whole instrument carries out when gas velocity should be less than or equal to the ventilation of 0.5 meter per second.Before placement sample, use the ignition wire 10 of ignition wire sampling die 8 production standard shape, carry out ignition wire 10 and install.After each off-test, need the ignition wire 10 more renewed.
First mix with the ratio of 3:1,1:1 and 2:1 with reference to material (calper calcium peroxide) and cellulose (by mass), after mixing, material mass is 30g, test mixture is put into conical hopper 21, solid matter is tamped, after ensureing stacking reversing, there is inverted-triangular structure.With sample preparation shovel 9 cover funnels, then by the two overturn, subsequently the two is placed on above load bearing board 18, take away sample preparation shovel 9, pat conical hopper, after conical hopper is removed.Stacking now covers the ignition wire 10 be placed on load bearing board 18, and now igniting starts test, and stacking takes fire.In certain combustion process the mass loss of stacking be less than 0.1g per minute time, burning automatically terminate.The reference potpourri of three kinds of ratios respectively should do 5 efficiency tests.Standard deviation within these 5 times tests must not add up to more than 10%.After the reference potpourri test of three kinds of ratios, can show that three kinds with reference to potpourri intermediate value combustion rate separately.
Next carry out 5 efficiency tests by after the ratio mixing of substances and cellulose (by mass) 4:1 or 1:1, concrete process of the test is as follows:
The first step: during start, confirms that current application program is opened, clicks " beginning data acquisition " button and starts whole test.Before the whole test of beginning, in the message box of on the left side, the parameter information that change needs.After clicking " beginning data acquisition " button, button becomes light tone.
Second step: start ignition wire sample preparation, ignition wire is placed in ignition wire mould, test instrument correctly places mould, and install ignition wire.On " optimum configurations " interface, click " ignition wire is shaping " button, button becomes light tone afterwards.And can observe, ignition wire end is rubescent, after about 5S, again clicks " ignition wire is shaping " button, stops heating, then take off ignition wire mould.Now complete ignition wire shaping for the first time.
3rd step: take off ignition wire mould, test instrument places load bearing board, then from ignition wire mould, ignition wire is taken out, test instrument is installed again, to install and after correctly placing ignition wire, now click " ignition wire is shaping ", button becomes light tone, and this operation makes ignition wire steadily drop on load bearing board.Now, click " operation peeling " below, after click, button becomes green, waits for about 10s, and " operation peeling " button becomes dead color, and peeling has operated.Click " ignition wire is shaping " button above, button becomes dead color, makes ignition wire stop heating.The second time now completing ignition wire is shaping, and completes peeling operation, below " operation peeling " button, show current peeling quality.Note when clicking " operation peeling " button, not adopting consecutive click chemical reaction.After having removed the peel, click " ignition wire is shaping " button, close heating.
4th step: enter lower one page by the button below interface, to " data display " interface, by sample preparation shovel and sample funnel, load bearing board places sample, observe " current Quality numerical value " display box, after the data stabilization that waits for a period of time, click " starting experiment process to control ", carry out the partial data recording process of whole test.Other buttons except the button of changing interface please don't be operated in this process, avoid the flow process affecting normal test.
5th step: after test specimen burning terminates, can point out user to select whether to continue the test of next time.User can select " determination " (when system prompts user carries out selecting " whether continuing the test of next time ".When user selects to cancel, system can point out user whether to exit experiment), carry out experiment next time.Now by the button below current " data display " interface, click lower one page and enter " generating report forms " interface, can see when time experimental data of record: as mass change, atmospheric pressure, humiture change etc., and related experiment result.On the right at interface, the curve of the related coefficient matching of current Quality data can also be seen.By clicking " generating report forms " button, generating when time experiment form, during preservation, noting renaming.
By clicking " lower one page " button below current interface, entering " data processing " interface, please click " adding current experiment result data ", " experimental result data table " form can be seen, wherein can increase when time result data of experiment.Attention: when experiment is carried out more than 5 times or 5 times time, user on the right side at interface, can choose 5 experiments, and click " calculating of standard deviation ", at this moment user in the lower right at interface, can obtain the data result of being correlated with.User can derive the total data form of current experiment by " statistical conversion ".
6th step: " substance combustion speed crosses slow or material is unignited as test prompting user! Please re-start experiment ", so when the data of secondary experiment can not calculate, user at " generating report forms " interface, can be derived when secondary experimental data by " generating report forms ".Then user can select to continue to get back to " optimum configurations " interface and carries out testing or directly exiting experiment.
If the intermediate value combustion rate of substances is greater than the intermediate value combustion rate of reference material and cellulose (by mass) 3: 1 potpourri, then this substances belongs to packaging classification I.
If the intermediate value combustion rate of test mixture is greater than the intermediate value combustion rate of reference material and cellulose (by mass) 1: 1 potpourri, and do not reach packaging classification I, then this substances belongs to packaging classification II.
If the intermediate value combustion rate of test mixture is greater than the intermediate value combustion rate of reference material and cellulose (by mass) 1: 2 potpourri, and do not reach packaging classification I and II standard, then this substances belongs to packaging classification III.
If the test of its (by mass) 4:1 and 1:1 compounding substances of any substances is not all ignited and burns, or intermediate value combustion rate is less than the intermediate value combustion rate of reference material (by mass) 1:2 potpourri, surveys this material and be not suitable for carrying out this test.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, without departing from the concept of the premise utility; can also make some improvements and modifications, these improvements and modifications also should be considered as in the utility model protection domain.
