EVA Packaging Firimu yeRubber Additives
ZonpakTMEVA yekurongedza firimu yakagadzirirwa kugadzira mabhegi madiki ekuwedzera erabha (eg 100g-5000g) ane fomu-kuzadza-chisimbiso (FFS) muchina webhegi. Akasiyana-siyana ekuwedzera erabha kana makemikari (semuenzaniso peptizer, anti-aging agent, curring agent, cure accelerator, rubber process oil) anowanzo shandiswa mukusanganisa rabha, uye zvishoma chete zvezvinhu izvi zvinodiwa pabatch yega yega. Saka aya mapakeji madiki anogona kubatsira vashandisi vezvinhu kuwedzera kushanda zvakanaka uye kudzivirira kutambisa zvinhu. Iyi firimu yakagadzirwa neEVA resin (copolymer ye ethylene uye vinyl acetate) iyo ine chaiyo yakaderera yekunyungudika uye kuenderana kwakanaka nerabha kana resin zvinhu. Saka mabhegi pamwe chete nezvinhu zvirimo zvinogona kuiswa zvakananga mumusanganisi. Mabhegi achanyunguduka uye achapararira mukomboni yerubha sechinhu chidiki chinoshanda.
Mafirimu ane nzvimbo dzakasiyana dzekunyungudika (65-110 dhigirii Celsius) uye ukobvu anowanikwa kune akasiyana mashandisiro ekushandisa.
