Identification method of medical silicone tube
Medical silicone tube is generally used for medical and health care, but also the national focus on monitoring. Production costs are generally higher than ordinary silicon
Hose, but ordinary silicone tube with a lot of similarities. So some black businessmen is to take advantage of this point to seek profits,
So really. There is a difference between the heat and the heat. The difference is the method of identifying medical silicone tube
. The following small series on the simple introduction of 6 methods.
1 medical silicone tube overflow
(1) standard: from key oriented, monochrome material is more than or equal to 1.0MM with shell height, casing after sight is appropriate.
(2) detection method: measuring using vernier caliper
2.
(1): standard positioning hole: the edge of the product: less than 0.5MM less than 0.1MM
3 rupture
(1) standard: no effect assembly and performance: less than 1.0MM
(2) detection method: measuring using vernier caliper
4 silicone tube color
(1). The standard: silicone is not exposed after the assembly, and no significant difference.
(2). Method: in natural light or 40W bright sunlight, the color and the standard samples or samples together after school,
More than 1 professional staff, no color in the eye and spacing samples for the case of 30cm inspection for 5 seconds.
5 medical silicone tube eccentric
(1): H - H standard thick elastic thin wall thickness less than 0.1MM, detection of X=20 percent die;
The elastic wall thickness less than 0.2MM, detection of X=15 percent die
H thick H thin elastic wall thickness less than 0.3MM, detection of X=8% mould
(2) detection method: test with a thickness gauge.
6 color point
(1) the standard: customer assembly after silicone exposed part: no obvious visible
(2) detection method: in the bright natural light or 40 Watt daylight lamp irradiation, the sample is placed in the eye of the eye from the eye of 30CM about 1
5 seconds above visual pharmaceutical grade medical silicone tube, silicone tube with internal medical silicone rubber, translucent, food and pharmaceutical grade
No, no smell and taste, mirror like surface treatment to strengthen the structure of high resistance polyester layer and implanted AISI304 spiral stainless steel wire table
The surface of silicone rubber, translucent, food and drug levels, no smell and taste, smooth surface. The surface more closely, not
Friction is caused by particles, which can be cleaned with different cleaning agents. Temperature range from -60 to 180 can be used for steam at 135, 180
C hot air disinfection work pressure, standard time is not more than 30 minutes of safety factor was less than 3 times in accordance with the food and Drug Administration and the European
Silicone rubber of European pharmacopoeia.
