真(zhen)空包裝機廠的真空(kong)包裝機增加充氣(qi)功(gong)能是(shi)(shi)(shi)有兩種(zhong)(zhong)(zhong)方式，一種(zhong)(zhong)(zhong)是(shi)(shi)(shi)氣(qi)嘴直(zhi)接(jie)伸到產(chan)(chan)(chan)品袋子里面(mian)進行充氣(qi)的，另一種(zhong)(zhong)(zhong)是(shi)(shi)(shi)把要(yao)充的氣(qi)體先(xian)充滿整個(ge)真空(kong)室，然(ran)后靠負壓差充滿袋子。那究竟采用哪種(zhong)(zhong)(zhong)方式充氣(qi)好(hao)呢，這(zhe)里主(zhu)要(yao)看(kan)客戶的產(chan)(chan)(chan)品性質(zhi)，單純來說肯定是(shi)(shi)(shi)直(zhi)接(jie)沖到袋子里比(bi)較(jiao)好(hao)，這(zhe)樣置換的又純還(huan)能省不(bu)少氣(qi)源，但(dan)(dan)是(shi)(shi)(shi)大家一定要(yao)考(kao)慮好(hao)自己產(chan)(chan)(chan)品性質(zhi)。如果產(chan)(chan)(chan)品是(shi)(shi)(shi)顆粒，我們可(ke)以采取起初一種(zhong)(zhong)(zhong)方法直(zhi)接(jie)讓充氣(qi)嘴到袋子里進行充氣(qi)，但(dan)(dan)是(shi)(shi)(shi)如果你的產(chan)(chan)(chan)品是(shi)(shi)(shi)粉末狀的就不(bu)能用起初一種(zhong)(zhong)(zhong)方法了，需要(yao)第二種(zhong)(zhong)(zhong)在真空(kong)室充氣(qi)利用壓力差充滿袋子。可(ke)是(shi)(shi)(shi)客戶又要(yao)要(yao)求達(da)到一定比(bi)例的殘(can)氧量，這(zhe)就很矛盾了。
