Professional terms and practical applications
1,1,1,2-tetrafluoroethane (HFC-134a): As an environmentally friendly refrigerant, it is widely used in automotive air-conditioning systems. Its molecular formula is C₂H₂F₄, and its relative molecular mass is 102.03.
Air tightness test: Leakage is determined by immersing the aerosol can in a 50±5℃ water bath to observe whether bubbles are generated. No bubbles are acceptable.
Implementation suggestions
Storage and transportation: The product should be stored in a cool and ventilated place, avoiding high temperature and direct sunlight. It should be handled with care during transportation, and no impact or squeezing is allowed.
Operation specifications: The filling personnel must undergo professional training and hold a certificate before taking up their posts, and wear protective glasses and gloves during operation. The original refrigerant in the system should be completely recovered before filling, and the remaining materials should be disposed of after completion.
