Dabar daugelyje pakuočių dedamos putos, kurios atlieka lėtos vibracijos vaidmenį ir neleidžia pažeistoms dalims pažeisti išorinių mechaninių jėgų.
Foam is made of shape molding machine. Do you know the working principle of shape molding machine? Let's have a look.
1. Formos formavimo mašinos apibrėžimas
Kai naudojama gaminiams pakuoti, medžiaga, galinti susidaryti plastiko putas, įpurškiama į tarpą tarp talpyklos ir plėvele išklotos vidaus, o mašina cheminės reakcijos būdu suformuojama, kad viduje būtų sandariai supakuota putplasčio amortizacinė medžiaga.
2. Putų formavimo mašinos veikimo principas
♥ 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.
