Emulsion pump is also called pressure emulsion pump, is a kind of liquid dispenser using the principle of atmospheric balance, through pressure will be the material liquid pump out of the bottle, and the outside atmosphere into the bottle. Main performance indexes of emulsion pump: air pressure times, pump output, downforce, head opening torque, rebound speed, water intake index, etc.
The dispenser is divided into two types: the tie type and the screw type. From the function, it is divided into the spray, the foundation cream, the emulsion pump, the air mist valve and the vacuum bottle
The size of the pump head shall be determined according to the caliber of the matching bottle body. The size of the spray shall be 12.5mm-24mm, and the water output shall be 0.1ml/ time -- 0.2ml/ time. It is generally used for packaging perfume, gel water and other products, and the length of the nozzle with the same caliber can be determined according to the height of the bottle body.
The size of emulsion pump head ranges from 16ml to 38ml, and the water output is 0.28ml/ time -- 3.1ml/ time. It is generally used for cream and washing products.
Special dispensers such as foam pump head and hand button sprinkler head, foam pump head is a kind of hand pressure pump head without filling air, no need to fill air to produce foam, only light pressure can produce quantitative high-quality foam. It is usually equipped with special bottles. Hand - buttoned sprinkler heads are usually used for cleaning products.
Distributor is composed of more complex, generally including: dust cover, snap head, snap rod, gasket, piston, spring, valve, bottle cap, pump body, suction pipe, valve ball (steel ball, glass ball). Bottle cap, dust cap can be done color, can be electroplated, can be set anodized aluminum ring.
Vacuum bottles are usually cylindrical, 15ml-50ml, some have 100ml, the overall capacity is small, depends on the principle of atmospheric pressure, can avoid the cosmetics in the use of pollution, vacuum bottles have anodized aluminum, plastic plating and colored plastic, the price is more expensive than other common containers, ordinary order requirements are not high. Distributor customers rarely open their own mold, the mold to pay more, the cost is higher.
