冰袋，廣泛用于水果、蔬菜、疫苗等物品的保鮮快遞運輸和醫(yī)用冷敷。目前市場普遍使用的是自吸式冰袋，這種冰袋的特點就是使用起來較為方便，可以有效改善傳統(tǒng)冰袋低效率注水的情況。
自吸式冰袋無毒、無味、無腐蝕，可重復(fù)使用，其有冷到時長是冰的3～4倍，可代替冰作為熱交換載體傳遞熱量的冷凍介質(zhì)。那么，在使用自吸式冰袋有哪些需要注意的呢？
首先，自吸式冰袋內(nèi)含有高分子蓄冷吸水材料，吸水性能強大，能自動吸收自身重量的幾十到幾百倍的水。
其次，冰袋內(nèi)材料吸水后成凝膠狀，請勿用力擠壓或與銳利物品接觸，避免過大的壓力導(dǎo)致冰袋破裂，從而影響其使用性能。
自吸式冰袋的正確使用方法：
1、只需將它放入水中浸泡 3～5分鐘，就能使其充分膨脹，免去人工注水的煩瑣操作。
2、待冰袋充分膨脹取出后擦拭冰袋表面多余的水分靜止5分鐘左右，再將冰袋放入冰箱冷凍6小時以上
溫馨提醒：泡沫箱+保溫袋+冰袋搭配使用的話保冷效果更好。
Self-priming ice pack non-toxic, tasteless, non-corrosion, reusable, its cold to 3 ~ 4 times the length of ice, can replace ice as a heat exchange carrier transfer heat freezing medium. So, in the use of self-priming ice pack what need to pay attention to?
First of all, the self-imbibition ice pack contains polymer cold storage water absorption materials, water absorption performance is strong, can automatically absorb their own weight of tens to hundreds of times the water.
Secondly, the material in the ice pack after absorbing water into a gel, do not squeeze hard or contact with sharp objects, to avoid too much pressure to lead to the rupture of the ice pack, thus affecting its performance.
The correct use of self-priming ice pack:
1, just put it into the water soaking 3 ~ 5 minutes, can make it fully expanded, without the tedious operation of artificial water injection.
2. After the ice pack is fully expanded and removed, wipe the excess water on the surface of the ice pack and rest for about 5 minutes, and then put the ice pack in the refrigerator for more than 6 hours
Warm reminder: The combination of foam box + insulation bag + ice bag can keep the cold better.
