Il-fowm issa huwa applikat f'ħafna pakketti, li għandu rwol ta 'vibrazzjoni bil-mod u jipprevjeni li l-partijiet bil-ħsara jiġu mħassra minn forzi mekkaniċi esterni.
Foam is made of shape molding machine. Do you know the working principle of shape molding machine? Let's have a look.
1. Definizzjoni tal-magna tal-iffurmar tal-forma
Meta jintuża għall-ippakkjar tal-prodott, il-materjal li jista 'jiġġenera fowm tal-plastik jiġi injettat fid-distakk bejn il-kontenitur u l-intern miksija bil-film, u l-magna hija ffurmata b'reazzjoni kimika biex tifforma materjal ta' ttaffi tal-fowm ippakkjat sewwa ġewwa.
2. Il-prinċipju tax-xogħol tal-magna li tifforma fowm
♥ 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.
