APRIL 2017 Page 7 of 7 A.0 GENERAL INFORMATION The equipment and adhesive manufacturers can provide direction in setting maintenance schedules, provide process checking methods, evaluate storage condi
47、tions, and instruct on proper stock handling procedures. The following are general guidelines that are usually true for most materials. A.1 Production Control Proper maintenance and equipment checks are necessary to ensure that the material is dispensed properly. Some techniques to assure the adhesi
48、ve is properly mixed and hardened are to check the mixture feeding into the gun by weight and to measure hardness at the edge of cured joints. A.2 Material Storage Base resin and accelerators shall be stored at ambient temperature below 38C (100F) away from all sources of heat and ultraviolet light. The adhesive resins and accelerators exhibit a marked decrease in storage life when not stored under stated conditions. Materials stored at temperatures below 21C (70F) shall be conditioned at am
