Medical silicone tube is generally used in medical and other aspects, and it is also a national key supervision. The cost of production is generally higher than ordinary silicone tubes, but there are many similarities with ordinary silicone tubes. Therefore, some unscrupulous businessmen use this to make huge profits, and then to fill the truth. Even if heat has similarities, then there must be differences. The difference is the method of identifying medical silicone tubes. The six methods are briefly introduced below.
Medical silicone tube overflow
(1) Standard: From the key surface downwards, the height of the monochromatic material is ≥ 1.0MM, and it is suitable to be invisible after the shell is installed.
(2) Detection method: Measure with vernier caliper
2. Medical silicone tube burr
(1) Standard: Positioning hole: ≤0.1MM Product edge: ≤0.5MM
3. Medical Silicone Tube Rupture
(1) Standard: No impact on assembly and performance: ≤1.0MM
(2) Detection method: Measure with vernier caliper
4. Silicone tube color
(1). Standard: Silicone is not exposed after vulcanization assembly, there is no big difference.
(2) .Detection method: Put the standard sample or color card with the sample to be calibrated under bright natural light or 40W fluorescent lamp. After the visual acuity is 1.0 or more, the color blind professional has a distance of 30cm between the naked eye and the sample Visual inspection for 5 seconds.
5. Eccentric medical silicone tube
(1) Standard: When H thickness-H thin elastic wall thickness ≤ 0.1MM, X = 20℅ during mold inspection; when elastic wall thickness ≤ 0.2MM, X = 15℅ H thickness; H thin elastic wall thickness ≤ 0.3 For MM, X = 8% during mold inspection
(2) Detection method: test with thickness gauge.
6. Medical Silicone Tube-Color Point Bump
(1) Standard: Exposed part of silicone after customer’s assembly: No obvious visible
(2) Detection method: Under bright natural light or a 40-watt fluorescent lamp, place the sample at about 30cm from the naked eye and visually inspect the pharmaceutical grade medical silicone tube for 5 seconds with a visual acuity of 1.0 or more. Food and pharmaceutical grade, no odor and taste, mirror-like surface treatment, reinforced layer structure, high resistance polyester layer and implanted AISI304 spiral stainless steel wire surface friction caused by particles, can be washed with different cleaning agents. Temperature range -60 ° C to 180 ° C Can be used for 135 ° C steam and 180 ° C hot air disinfection for less than 30 minutes. Safety factor ≥3 times the working pressure standard complies with the silicone rubber of the Food and Drug Administration and the European Pharmacopoeia.
