Skum appliceras nu i många förpackningar, vilket spelar en roll som långsam vibration och förhindrar att de skadade delarna skadas av yttre mekaniska krafter.
Foam is made of shape molding machine. Do you know the working principle of shape molding machine? Let's have a look.
1. Definition av formgjutningsmaskin
När det används för produktförpackning injiceras materialet som kan generera plastskum i springan mellan behållaren och den filmklädda insidan, och maskinen formas genom kemisk reaktion för att bilda skumdämpande material tätt packat inuti.
2. Arbetsprincipen för skumbildande maskin
♥ Foam will not emerge from the sky. It must be made by special process for foaming equipment.
♥ Foaming equipment is a device that can make a certain concentration of water solution (foaming agent) into foam.
♥ Foaming agent itself can not automatically become a bubble, it must through foam machine's mechanical function can become a bubble.
♥ The foaming equipment itself can not produce bubbles without any cost. It disperses the air into the foaming agent aqueous solution evenly and realizes the contact surface of the liquid gas as large as possible, so that the surface active substances in the foaming agent form a double electric layer on the liquid film surface and encircling the air, forming bubbles.
♥ Foaming machine and foaming agent are a technical system that cooperate with each other and can not play a role alone.
