Description
Technical field
The present invention relates to colour fastness testing apparatus, specifically a kind of colour fastness based on hot air circulating system temperature control tests the contact device that automatically bears a heavy burden, and can be used for the constant temperature heavy burden engaged test process that the mouth such as textile or cigarette tipping paper touches the product colour fastness of resistance to saliva.
Background technology
Colour fastness refers to the resistibility of the Color pair of article various effect in processing and use procedure, reflects the firmness of the attachment of colorant on article.The colour fastness of resistance to saliva can touch the article in oral cavity when being mainly applicable to routine use or expection use, as toy, textile and napkin paper etc.The colour fastness of resistance to saliva is one of important indicator weighing this kind of commodity quality good or not, if colorant attachment is firm not on this series products, soaked by saliva and phenomenon of fading or fade may be caused under the effect of lips and teeth pressure, thus consumer may be caused to eat colorant and coming to harm, directly affect the security of product.4 grades should be more than or equal to the colour fastness of resistance to saliva of infant clothing in China compulsory standard GB18401-2010 " National Textile basic security technical manual ", European Council in " Policy Summary about thin page towel paper for kitchen use and napkin paper " in regulation napkin paper and kitchen towels paper the migration amount of colorant at least reach 4 grades of fastness requirements, China's tobacco business counterpart touches material---cigarette tipping paper also makes the colour fastness of resistance to saliva index request.
For above product, current every profession and trade has put into effect the relevant colour fastness of resistance to saliva testing standard respectively, the adjacent fabric of sample and regulation fits together by GB/T18886-2002 " textile color stability tests the colour fastness of resistance to saliva " regulation up and down, after infiltrating in simulate saliva, to be placed in test unit between two flat boards, pressure (37 DEG C, 4h, 12.5kp) is applied under uniform temperature and time effect, then by sample and adjacent fabric drying respectively, with the gray scale evaluation variable color of sample and the staining of adjacent fabric.And for the colour fastness of the resistance to saliva test process of napkin paper and cigarette tipping paper: by sample with fit together by the all-glass paper that saliva simulated solution infiltrated, under uniform temperature and heavy burden pressure condition, place a period of time (napkin paper: 23 DEG C, 10min, 1kg; Cigarette tipping paper: 40 DEG C, 10min, 1kg), reference standard gray scale, the staining fastness rank of rear all-glass paper is dried in evaluation.Two methods difference to some extent on contact conditions can be found out, but procedure is identical with principle, there is a common ground---constant temperature and pressure heavy burden contact process, namely need in isoperibol, specific pressure is applied to detection sample, and keep the specific time, the time to after to exert pressure end, heating stops.
Now in the art, commercially available a kind of saliva of textile colour fastness testing jig, applies certain pressure with weight, puts into baking oven control temperature, cannot temperature control, self-clocking and automatically cancel pressure.There is no special device in the market, in the colour fastness of resistance to saliva testing process, can realize in constant pressure, self-timing situation, carrying out heated at constant temperature to detection sample, timing heats to rear stopping, stopping exerting pressure.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of colour fastness based on hot air circulating system temperature control is provided to test the contact device that automatically bears a heavy burden, this device can in the cigarette tipping paper colour fastness of resistance to saliva testing process, there is provided the internal environment of sealed thermal insulating, during test, sample is sent in test chamber automatically, imposes constant pressure to sample, and self-clocking, sample by counterweight jack-up, and is sent sealed thermal insulating shell to exhaust hood by timing, reaches experiment purpose.
The object of the invention is to be achieved through the following technical solutions:
A kind of colour fastness based on hot air circulating system temperature control tests the contact device that automatically bears a heavy burden, comprise base plate, detain the airtight lagging casing be placed on base plate, the base plate being arranged in lagging casing cavity is provided with one automatically to bear a heavy burden mechanism for testing, this automatic heavy burden mechanism for testing by can translation loading detection platform and with loading detection platform with the use of and the flat test counterweight that can rise or press in loading detection platform form, flat test counterweight controls to move up and down by the lift cylinder be arranged on the base plate of loading detection platform both sides, loading detection platform is moved by the horizontal air cylinder level of control being arranged on the outside side of lagging casing and open and close door by lagging casing opposite side is released, circulating hot air channel is had with the base plate lower disposed being positioned at lagging casing in the top outer of lagging casing, and on lagging casing with base plate, offer multiple hot wind inlet for being communicated with hot-flow flue and inner chamber and hot-blast outlet respectively, on lagging casing two side body, correspondence offers air admission hole and vent port, temperature sensor is provided with in lagging casing cavity, be used for real-time detected temperatures feed back to controller.
