表面张力测试液 达因液 美国进口1盎司/瓶美国ACCU TEST测试液能准确的测试出塑料薄膜之表面张力是否达到测试液的数值。令使用者清楚的了解此薄膜是否适合于印刷，复合或真空镀铝。有效的控制质量及减少因材质不合格所造成的损失。它并不仅限于塑料薄膜，还可以测试各种材料的表面张力。原装进口测试液有30-72数十个品种。一般来说，基材形成墨滴，涂层和粘贴能力和表面的能量相关。如果基材表面的能量低于所涂测试液的表面的张力，则形成珠点和画线收缩。因而，对大多数的基于印刷，塑料的溶剂来说，测试笔的要求在36-40达因/厘米之间。基于墨的些液体要求测试笔在40-44达因/厘米之间。而一些碾压和涂层的应用要求表面能量在50达因/厘米或者以上。显而易见，在进行印刷，涂层和碾压前需要对表面的能量先预估。ACCU TEST测试液在绝大多数的非粘贴性的材料上表现良好。重要的是测试液不会改变基材的表面特性。例如，如果测试液渗入一个纤维基材（如纸）致使膨胀，结果可以说明其容易潮湿。基材和测试液间的生化反应使结果无效。为了确保测试结果的可重复性，材料的准备和测试的方法必须标准化。ASTM STD D6182协议规定了测试条件以及方法。For Medical & Emergency OnlyMATERIAL SAFETY DATA SHEET1.PRODUCT INFORMATIONPRODUCT NAME: ACCU TEST CHECK PENS 30-60NFPA Hazard Signal Health 1; Stability 0; Flammability 0; Special C2.PHYSICAL DATABOLING POING: 135 C to 210 C Freezing Point -90 C to +2 C(at 760 mm Hg) (at 760 mm Hg)SPECIFIC GRAVITY: 0.93 to 1.13 Vapor Pressure, 0.08 3.75at 20 C (H20 = 1.0) mm Hg, at 20 CVAPOR DENSITY: 3.1 Solubility in water, CompleteAt 20 C (air = 1) % by wt.

May cause headache, nausea, vomiting, weakness.Skin Contact: May cause irritation. Wear protective gloves.Ingestion: See inhalation: can also cause breathing difficulty. Kidney damage may result from ingestion of large quantities of test solution.Skin absorption: Prolonged or widespread contact with skin may lead to absorption of harmful amounts of materials resulting in symptoms as described under ingestion.Eye Contact: Cause marked irritationSPECIAL WARING: pregnant women should not use this product; laboratory studies of animal subjects have shown birth defects, delayed fetal development, and increased fetal mortality at air concentrations of 150 to 200ppm.6.EMERGENCY AND FIRST AID PROCEDURES:Eyes: Flush liberally with running water. Call a physician.Skin: Immediately remove contaminated clothing. Thoroughly wash affected area with soap and water.Inhalation: Remove to fresh air. If breathing if difficult, give oxygen and call a physician.Ingestion: Give large quantities of water. Induce vomiting. Call a physician.7.REACTIVITY DATA:Decomposes partially at temperatures above 180 Celsius. Do not combine with concentrated alkali at elevated temperatures.Hazardous combustion or decomposition products: CO, NHx.8.SPILL OR LEAK PROCEDURES:Absorb spill with paper toweling or vermiculite. Once absorbed, evaporate outdoors or incinerate in a chemical burner equipped with an after-burner and scrubber.Dispose of waste product by high temperature incineration, as approved under appropriate federal, state and local legislation. Do not discharge without prior written approval from the appropriate health and environmental authorities.ACCU TEST CHECK PENS Page 39.SPECIAL PRECAUTIONS:NOT FOR USE AS A CONSUMER PRODUCT. FOR INDUSTRIAL USE ONLY.Keep this product away from heat and flame. Always use with adequate ventilation. Do not allow fluid to contact skin; wear gloves.WARNING TO PREGNANT WOMEN: Do not use ACCU TEST CHECK PENS unless exposure is extremely low. Even small amounts, if repeatedly inhaled, ingested, or absorbed through skin, may cause fetal malformations.10.HANDLING AND DISPOSAL GUIDE:ACCU TEST CHECK PENSFlexart Inks, Paints & Coatings, Inc. strongly recommends you wear protective gloves while using these test marker pens; skin contact presents the highest potential for exposure under normal testing conditions. Eye protection and a laboratory coat or apron are also good precautions.Ventilation must be adequate to ensure that vapors will not accumulate; and exhaust hood is ideal, though not absolutely necessary as long as there is reasonable airflow in the test area.Spent material samples must be handled with care: Disposal of these contaminated materials also presents exposure hazards. We suggest you allocate one trash container exclusively for dyne test waste; use an inner liner, keep it covered, and label the lid.“DO NOT HANDLE THIS WASTE WITHOUT PROTECTIVE GLOVES. AVOID SKIN CONTACT.”Outdated pens should be dispositioned by your in-house industrial waste expert via your contracted waste handling firm. The EPA classifies the constituents of these pens as generic solvents, but your local regulations may be more stringent. ALWAYS REVIEW THE MSDS WITH YOUR WASTE- HANDLING FIRM TO ENSURE PROPER HADLING.While Flexart Inks, Paints & Coatings, Inc. believes the information contained herein is factual and the opinions expressed are those of qualified experts, this information is not to be taken as a warranty for which While Flexart Inks, Paints & Coatings, Inc. assumes legal responsibility.

FLEXART ACCU TEST CHECK PENS TESTING METHODSACCU-TEST CHECK PENS perform well on most non-absorptive materials.Do not touch or in any way contaminate the surface to be tested.Do not use contaminated or outdated ACCU-TEST CHECK PENS.Never retest the same location on a sample: move along the sample, or pull a new one.Store ACCU-TEST CHECK PENS at room temperature.Pull test sample. Make sure you pull a good sample specimen.For extruded film, one entire web cross-section should be okay. Do not touch the surface. Place the sample on a clean, level surface. Always go left to right in order to maintain the same consistency.Record ambient temperature and relative humidity. If sample temperature differs from ambient, allow it to stabilize.A minimum 3 sample points should be test: 1/4, 1/2 and 3/4 across the film section. It is good practice to test the outer edges as well. For non-film materials, test locations must be determined in-house.Determination of wettingChoose a ACCU-TEST CHECK PEN, which you believe, is slightly lower than that of the subject material.1.1 Use a light touch to draw the pen across the test pen from left to right in two or three parallel lines. Disregard the first pass.1.2 If the last swath remains wetted out on the test sample for three seconds or more, repeat the step 1.1 with the next higher dyne level pen. If the last ink swath beads up, tears apart, or shrinks into a thin line within on second or less, repeat step 1.1 with a lower level pen. If the ink swath holds for one to three seconds before losing its integrity, the dyne level of the pen closely matches that of the sample.This is relatively accurate surface energy measurement technique: used in standard 2 dynes/cm increments.To investigate discrepancies between obtained and expected results, a more precise measurement method should be considered: application ACCU-TEST SOLUTION surface tension test fluids with cotton swabs (per ASTM D2578-84) or by use of a draw down rod is recommended. Alternatively, if results are suspect, replicate the test with a set of unused pens. This test
