The production process of varying nitrile gloves is different. The nitrile gloves produced in the clean room are divided into class 100 and class 1000 according to the production environment, production process, and product application field. Then what is the difference between these two nitrile gloves in the production process?
Raw Material Handling
Nitrile gloves are raw materials for nitrile latex, but Class 100 nitrile gloves need higher-purity filtration treatment to reduce impurities. Heavy metal content is strictly limited. Class 1000 nitrile gloves have low cleanliness requirements but still need to avoid large particle contamination.
Production Environment
The production environment requirements of Class 100 gloves are relatively higher, requiring the number of dust particles greater than or equal to 0.5 microns per cubic meter of air in the glove production workshop to be controlled within 100, the air is continuously purified through the air purification system (such as HEPA high efficiency filter), and personnel need to go through strict cleaning and changing procedures such as air shower and disinfection.
Class 1000 gloves are required to be produced in thousand-grade clean workshops, and the number of dust particles greater than or equal to 0.5 microns per cubic meter of air is not more than 1000 to reduce dust, microorganisms, and other impurities attached to the gloves.
Additive Control
Additives such as vulcanization agents and antioxidants added to Class 100 nitrile gloves must meet high standards, such as food grade, medical grade, or electronic grade to ensure that harmful ingredients are not released and the clean performance of gloves is not affected.
The type and dosage of additives for Class 1000 nitrile gloves are strictly controlled, and low-volatility and low-mobility additives, such as high-performance antioxidants and antistatic agents, are usually added to improve the durability and antistatic performance of gloves without affecting their cleanliness.
Cleanliness of Production Equipment
Several processes in the production process of Class 100 nitrile gloves, including dipping, vulcanization, cleaning, etc., need to be carried out in a higher clean environment, regular deep cleaning and maintenance of the production machine, the material can not pollute the gloves, to ensure that the production process does not produce particles, oil and other pollutants to avoid secondary pollution.
– Forming and processing process: glove forming, vulcanization, and other processing links, temperature, pressure, time, and other parameters control accuracy requirements are high, to ensure uniform and stable physical properties, avoid defects caused by improper process, and ensure cleanliness.
– Packaging materials: The packaging process is usually completed in a sterile environment, and some products need to be sterilized by ethylene oxide (EO) or irradiation. The packaging materials are strictly cleaned and treated, which do not release particulates and harmful substances themselves, and are mostly vacuum packaging or sealed packaging to prevent external pollution.
– Testing method: Advanced testing equipment and strict testing methods such as laser particle counter, high-performance liquid chromatography, microbial culture, etc., are used for comprehensive testing of all indicators of gloves, and key indicators may be fully inspected.
Class 1000 nitrile gloves have relatively low requirements for a clean environment in the production process. However, the production process is also fine, the production equipment cleaning and maintenance requirements are high, and the quality inspection process is strict and frequent to ensure that the gloves meet high cleanliness standards.
