Why Are Nitrile Gloves Popular?
Nitrile and PVC gloves are the mainstream of disposable protective gloves, and nitrile gloves account for a large proportion of the disposable gloves market. At the same time as the total demand for disposable health protective gloves increases, the structure of product demand is also changing.
PE gloves are often used in the food processing industry because they are not close to the skin. They are not easy to use and not flexible enough, and it is easy to break, so the lower price is the low-end product in disposable health protective gloves. PE gloves are often used by people because of their low price.
The advantage of latex gloves is that they are elastic and comfortable to wear, but their material contains collagen, which is easy to cause some human allergies.
The common feature of nitrile gloves and PVC gloves is that they have good waterproof, acid, and alkali resistance and chemical resistance, and are widely used in many production and living fields. The good wear resistance of nitrile gloves is widely used in the fine processing and manufacturing of electronic products, mechanical maintenance household cleaning fields beauty salons,s and other industries.
Nitrile and PVC gloves are replacing some latex gloves in the field of in vitro examination because they have the elasticity of latex gloves and are close to the skin without allergy risks. Nitrile gloves have become the mainstream products in the disposable gloves incremental market due to their excellent performance in anti-static, tensile, comfort, oil resistance, and other aspects.
Nitrile Gloves Are In High Demand
Nitrile gloves because of its unique material properties are widely popular, their advantages are antistatic, good tensile, comfort, oil resistance, wear resistance, etc., mainly used in medical protection, health and health protection in the field of protection strength, dust, chemical resistance, oil resistance and mechanical protection and other high requirements of the scene. Nitrile gloves are the higher end of disposable protective gloves. Compared with gloves of other materials, nitrile gloves are new materials and are gradually recognized by users around the world, so the production demand is large.
Nitrile PVC gloves were invented in the late 1950s, and in the process of AIDS being identified and concentrated in the global outbreak around the 1980s, the demand for nitrile PVC gloves increased sharply in the European and American markets, with the implementation of mandatory directives and regulations on hand protection for medical personnel in Europe and the United States and other countries. The medical care field has formed a good sense of the use of nitrile PVC gloves.
From the medical gloves category, nitrile PVC gloves belong to the stock varieties, although the growth rate of demand is not large, the huge historical long-term customer base and low production costs can still ensure its huge market demand. Chinese enterprises in the 1990s began to introduce nitrile PVC gloves production technology, after years of innovation and improvement, nitrile PVC gloves production technology has made a qualitative improvement. At present, the domestic nitrile PVC glove production technology has been very mature, and the vast majority of the global PVC glove production capacity is concentrated in China.
Performance of Nitrile Gloves
Fengwang nitrile glove manufacturing machines produce nitrile gloves with the following properties:
- Smooth inside and astringent outside, easy to wear, extremely durable.
- Textured gloves that can grip wet or dry touches.
- With anti-acid, anti-alkali, wear resistance, and oil corrosion resistance, itself without static electricity.
- Because it does not contain water-soluble protein and no chemical residue after process improvement, there is no skin allergy.
- Gloves pull and elastic, wear close to the skin, suitable for fine parts processing.
- Because the combination of nitrile polymers is very tight, under strict testing, the function of the pulled nitrile gloves against AIDS, hepatitis B, and other bacteria is stronger than that of latex gloves and other gloves, so that medical personnel and other industry personnel get the best safety guarantee.
- Nitrile gloves have the elasticity of latex, but after tensile expansion, they will not immediately rebound, and the fatigue of the hand can be solved.
- Clinical trials have shown that reed-coated nitrile gloves can also deeply moisturize and beautify white skin.
How Are Powder-free Nitrile Gloves Made?
The cleaned and dried glove former is sent into the nitrile glove raw material tank and dipped in polymer solution at 25-35℃. After dipping, the glove former must go into the oven and dry under hot air of 100-150℃.
Send the dried glove former into the glove beading machine for beading. The open-end edge of the newly formed nitrile glove on the glove former is rolled under the action of the glove beading machine. At this time, the glove former needs to enter the oven again and dry again under the hot air of 110-160℃;
After drying, the glove former must be sent into the chlorine washing tank. At this time, the glove former is chlorinated in the chlorine lotion at 35-65℃ to clean out the remaining protein in the film. Then the glove former after chlorine washing is sent to the drop tank for water shaking, and the glove former rotates rapidly to get rid of the chlorine lotion; Then the glove former is sent into the oven and dried under the hot air of 130-150℃;
The dried glove former is sent to the glove stripping machine, and powder-free gloves are formed after stripping.
Quality Inspection of Nitrile Gloves
Gloves are a very commonly used tool in daily life and are often very strict in the production and manufacture of gloves, and it is very important to test for compliance with glove standards. What kind of equipment can quickly test nitrile latex gloves? What are the characteristics of such an instrument?
The products of nitrile glove have excellent oil resistance, high wear resistance, and good heat resistance. They are made of high-quality nitrile butadiene rubber with other auxiliaries. Does not contain protein, strong and durable, good adhesion. Nitrile gloves are widely used in household work, electronics, chemical, aquaculture, glass, food and other factory protection, hospital, scientific research, and other industries.
Nitrile latex gloves tensile testing machine JM-101PT is a special test glove of an electronic tensile testing machine, according to GB/T2611 test and general technical conditions, according to GB/T 2792, JB/T2872, GB/T10424, GB/5319 and other relevant standards. Tension machine detection force range: 0.05KN~10KN.
The purpose of the quality inspection of nitrile gloves is not to break during stretching or use, and the glove must have sufficient elastic properties and be subjected to stresses such as hook force, fingertip force, force exerted by sharp tools, foreign objects, or equipment operated with gloves.
Glove testing is the method used to ensure the specified reliability for use, including the following mechanical tests, tear strength tests on stitched or seamless gloves, including hand-aged gloves, tested according to ISO 37, three-shouldered test rods are passed through the palm, back and wrist of the sample glove, parallel to the vertical axis, and structural areas should be avoided.
Nitrile latex gloves tensile testing machine operation steps:
- Input the parameters of the test machine sample, when setting the parameters is divided into two parts, sample parameters and preset parameters and results, for the sample parameters this part of the knowledge set for the helical spring, when the sample is a disc spring, plate spring, these parameters can not be filled in, not filled in the parameter report is not printed.
- After the parameter setting, place the sample in the central position.
- Set the test parameters, the test speed should not be too large, otherwise, the test results will not be accurate.
- Start the test when ready. Point button test starts to start the test, the test is automatically ended after the completion of the test, you can also point the test introduction button to end the test during the test.
