9) other every basic indexs of detection product, detection method is as follows, and the results are shown in Table 1.
Smell is tested：
With vial, the sample of 80g is weighed, it is with aluminium foil that bottle sealing is good, it is put into 160 DEG C of baking ovens and melts, after fusing,
The smell size of the parallel several hot melt adhesive of comparison of several individuals is looked for, and is made a record.
Hardness test：
Examination hardness is measured with shore A type hardness testers.
Open hour test：
With vial, a certain amount of glue sample is weighed, 160 DEG C of baking ovens is put into and melts, with 120 μm preheated of bar,
Glue is coated on the brown paper of 120gsm, every 5s clocks in a piece of calf-skin scraps of paper of upper face paste, and is firmly pressed.About 5 points
Zhong Hou tears the scraps of paper posted, wherein the time point that about 50% paper is broken, the i.e. open hour of the hot melt adhesive.The above test is repeated,
It reaffirms an open hour, and notes down.
Viscosity measurements：
It is tested with reference to the standard of GB/T2794-1995.
Softening point is tested：
The steel ball of determining quality is placed on the becket for filling up sample, under defined Elevated Temperature Conditions, steel ball enters examination
Sample, falls from certain altitude, and the temperature when steel ball touches underlying metal baffle is considered as softening point.
The specific test method is as follows for softening point：
(1) preparation of sample：
Aluminium-foil paper is converted into bowl-shape, taking a certain amount of sample to be placed in aluminium-foil paper bowl, (amount of sample should fill two examinations enough
Sample ring, and slight surplus).Aluminium-foil paper bowl and sample are put into togerther in electrically heated drying cabinet, setting temperature (setting temperature be more than
Sample starts 25-50 DEG C of the temperature of fusing), heating makes sample be completely melt.
It is relatively uniform for particle, fusing after do not overflow and have certain viscosity, will not because after fusing with sample loop bottom
Particle directly can be placed in sample loop directly fusing and (paid attention to by the sample of edge outflow：It to be filled out enough after the amount fusing of sample
Full sample ring, and slightly redundance after cooling).
Test button ring is put on a metal plate, to avoid bonding, can wrap up on a metal plate one layer of silicon facial tissue or
A little glycerine or silicone oil are slightly applied in metal sheet surface.
Sample ring is filled up with the sample of the fusing of sufficient amount, and makes its slightly redundance after cooling, in room temperature sky
Then air cooling at least 8h removes extra sample with slightly hot knife, specimen surface and ring surface is made to be in same plane.(note
Meaning：Wearing heat resistant gloves prevents from scalding).
(2) beaker is filled with glycerine, the amount of glycerine will submerge sample ring, and liquid level should be higher by sample ring 50mm,
(3) instrument and softening point test device are got out, thermometer has been hung, keeps the bottom of thermometer flat positioned at sample ring
Face, and it is equal at a distance from two rings, and regulation ring is put up horizontal.
(4) electric jacket heater switch is opened, is uniformly heated up, heating rate is adjusted, it is 5 ± 1 DEG C/min to make heating rate, is added
Hot glycerine bath temperature, until steel ball enters sample through sample ring.
(5) it when the steel ball surrounded by sample touches the bottom deck of ring stand, to record in time shown by this chronothermometer
Temperature, indicated (DEG C) with Celsius temperature.
(6) power supply is closed, test equipment is cleaned out.(when cleaning instrument, wear heat resistant gloves, prevent from scalding).
It is measured by the above method, the detection knot of the APAO filter lines glue prepared by 1-3 of the embodiment of the present invention
