The car detects with metalloid material technology

4 kilograms raise current 150-180 kilogram. In the meantime, field is corresponding to this kind of material of function detect raised taller requirement, for example volatile of material of car interior trim pledges the condensation on windshield drives to be affected safely to the driver, the permeability of plastic fuel box, of inner tube, safe gasbag cut off the gender is waited a moment. Be aimed at these problems, detect accordingly accurate, testing instrument also rolls out mark of method, check in succession and perfect ceaselessly. Interior trim pulverization detects material of the adornment inside the car, like the project plastic, textile, leather, without spin cloth to wait, and all sorts of adhesive that install these stuff place to use, below the action of high temperature, the component that its volatilize easily can evaporate come out, form on car window or windshield condense, cause driver line of sight undesirable, affect safety of drive a vehicle badly. Current, abroad already had this side detect, the relevant test standard that follow is IN 75201, ISO 6452, SAE J1756 to wait. Domestic share car and interior trim manufacturing company perhaps tastes character to raise high yield, or to develop the need of abroad field, right also relevant detect gave enough take seriously. Interior trim pulverization detects have method of two kinds of experiments: Glossiness tests law and weight test standard. Former the change that is the glossiness after passing vitreous board to be before pulverization will measure by the pulverization character of test sample; Latter is the quality that through aluminum foil the change in pulverization around quality gets pulverization coagulation. Additional, reach through the experiment " the value that become mist " or " pulverization - the quality of coagulation " still reach the volatilization of poisonous and harmful material measures this sample can mensurably; Through be worth a test to pulverization of the xenon lamp before the car, the pulverization phenomenon that still can check car headlight can be in how old illuminance of the influence on degree. The pulverization test equipment that sells on Chinese field at present has Germany to breath out Jinan of gram, China the brand such as Lan Guang. Fully the air permeability of seat material, wet sex detects in long-distance and itinerary in, drive often should take a few inside the car by personnel even a few hours, so of car seat material breathe freely, fully wet performance is higher than asking elsewhere. Good seat cushion, rely on chair should soft bouncy, have breathe freely goodly, fully wet function, make draw the sweat liquid that takes staff smoothly eduction, make the person feels comfortable. Of air permeability detect the method is: Inside the pitch of sample park experiment that takes set dimension, manage to find time in sample a side, make two side form sample to press difference certainly, press next poor measurement here gas passes sample to give the flow inside the area inside proper time, computation breathes freely rate; Perhaps maintain the flow that passes sample, survey sample of two side press difference, computational airiness obstruction. This test method abides by GB/T10655-2003. Of fully wet sex detect the method is: Place ground of sample constant temperature between dry wet antrum, the sensor that is located in test antrum analyses the change of the humidity inside antrum, dog by the time that sets floor level value to upper limit to be worth place to need beforehand, mix through be being measured for many times continuously systems analysis, beg those who give sample to appear wet quantity and fully wet coefficient. This test method abides by ASTM E398. The permeability of plastic fuel box can be measured at present the utilization rate of plastic fuel box of Chinese car already was achieved 86% . Light gasoline tank photograph to compare with armor plate, plastic fuel box has the car safer, anti-corrosive, service life is long wait for character, and modelling cost of optional, production is low. But, the car is plastic of fuel box cut off performance is poor, the penetrability that can create fuel volatilizes, need cuts off to its function has a test, in order to choose good stuff. Traditional test method is: After the benzine infuse gasoline tank ration, sealed, metage fuel box gets its quality M1, after setting enough time (want to exceed 100 days commonly) , undertake metage gets its quality M2 again, computational △ M=M1-M2, △ M is measured for the volatilization of fuel namely. This kind of method needs to check time to grow, the requirement has the metage tool of high accuracy, it is more difficult that implementation rises. ASTM D3985 gave out method of additionally one kind of test. Cut the plastic chip that takes fuel case, the oxygen that measures chip passes through a quantity, through undertaking comparative to the quantity appearing oxygen of all sorts of plastic chip, reach which are planted quickly thereby plastic have more cut off goodly quality, more comfortable make fuel case at be being used. ASTM F1307 gave out the test method of whole container, the check that realized sealing of whole gasoline tank thereby checks check. The gas of inner tube, safe gasbag cuts off the gender detects the material of production car inner tube and safe gasbag asks to have cut off goodly quality, former make sure the car moves for long and need not aerate, latter assures to sending the instant that make trouble reason collides, can rapid beat rises, assure to have constant pressure. The tradition detects the method comes to aerate finished product inner tube or safe gasbag constant pressure, right now pressure expresses a value below the record, after setting period of time, observe what pressure expresses a value to press fall, reach its cut off thereby function. This kind detects the method wants for a long time to just can reach commonly result (need above one year sometimes) , it is more difficult that implementation rises. Can use permeameter of the VAC-V1 that limited company of technology of Jinan orchid smooth Electromechanical produces gas now, in the sampling on the material that be measured, outfit clip is on the instrument, make two side maintain sample to press difference constantly, after measuring aeriform ooze to pass sample, pressure follows the change of time, reach thereby of material cut off function. The test that does this side on this instrument is general 12 hours of less than are achievable, improved work efficiency greatly. Other is metalloid of material detect the metalloid data that uses on the car is very much, and same kind material is used in different position to have diverse performance demand, also need those who have all sorts of projects to detect. For example tensile strength, tear strength, hardness, flexural strength, colour and lustre, coefficient of friction is waited a moment. Additional, various adhesive still can be used in great quantities on the car, the stand or fall of adhesive function is right truckload quality has crucial effect, undertake cutting to this kind of metalloid material even so, the function such as drawing, avulse checks.
