I. Production line control.
① When nitrile glove machine for sale’s the boiler oil temperature reaches 190℃, the production speed ≤m ≤65pcs/min.
②When the boiler oil temperature is lower than 145℃, the speed should be reduced accordingly according to the degree of drying of the rubber film.
③ when the boiler oil temperature is lower than 130 ℃ should be immediately taken to stop processing.
Second, impregnating nitric acid solution: nitric acid concentration should be controlled at 3%-4%, adding nitric acid solution to the nitric acid tank must be configured in advance with the same concentration of solution, the operator is strictly prohibited to add water or nitric acid to the tank at will.
Third, impregnating alkaline water: 5-10Kg of alkali is added to the alkali tank in each shift during normal production, and 1 time after 4 hours in the next shift.
Four, hand mold brushing: ① brush tank temperature should be controlled at 45 ± 15 ℃
②Mold washing water should be kept overflowing and constantly updated with water quality, and the water quality should be thoroughly updated once every 8 hours.
③Mold washing brushes should be frequently checked for hair wear to ensure brushing effect.
④Mold washing brushes are absolutely forbidden to be stained with oil substances.
Three dipping hot water.
① hot water tank temperature should be controlled within the range of 80 ± 15 ℃, the water quality is constantly updated to maintain the overflow state. Each acid hand wash mold to be replaced 1 time.
Four, impregnating starch coagulant.
① starch coagulant CaCL2 content control at 8±3%.
②Starch coagulant temperature requirement 65±15℃.
③ Starch coagulant should be thoroughly stirred once every 50-60 minutes.
③ starch coagulant every 4-8 days to thoroughly update 1 time.
V. Starch coagulant drying: ① hand mold out of the oven should be kept dry but hand mold slightly wet feeling.
