一次性紙餐盒應(yīng)該如何做好防潮處理?包裝一次性紙餐盒在進行防潮處理的時候,不只要保護包裝物不受水的浸濕,還要防止水對一次性紙餐盒自身的浸濕。
How to do moisture-proof treatment for disposable paper lunch boxes? When packaging a disposable paper lunch box for moisture-proof treatment, it is not only necessary to protect the packaging from water, but also to prevent water from wetting the disposable paper lunch box itself.
因為一次性紙餐盒在水浸濕后,它自身的抗壓強度、耐破度都會下降,這樣會嚴重影響包裝的質(zhì)量。包裝一次性紙餐盒進行防潮制造,一般選用涂布防水劑的方法來處理。因而,依據(jù)防水劑的作用可以將防潮一次性紙餐盒的制造方法分為:暫時性防水處理和持久性防水處理。
Because after the disposable paper lunch box is soaked in water, its compressive strength and bursting strength will decrease, which will seriously affect the packaging quality. The packaging of disposable paper lunch boxes for moisture-proof manufacturing generally adopts the method of coating waterproof agent. Therefore, according to the function of waterproof agent, the manufacturing method of moisture-proof disposable paper lunch box can be divided into temporary waterproof treatment and permanent waterproof treatment.
在一次性紙餐盒市場上包裝一次性紙餐盒在生產(chǎn)過程中選用暫時性防水劑處理后,具有暫時防水功用。當水短時間落于其上時,不沾濕而成水滴,能防止水浸透紙板。包裝一次性紙餐盒這種涂料早期用于織物纖維上,后來才用于紙板的處理。因而大多樹一次性紙餐盒廠就選用拔水劑的叫法。拔水劑是一種蠟乳液,固體含量一般為:48%~51%,它的特點是在運用時可用30倍左右的水稀釋。
In the disposable paper lunch box market, the disposable paper lunch box has temporary waterproof function after being treated with temporary waterproof agent in the production process. When water falls on it for a short time, it will not get wet and become water droplets, which can prevent water from soaking the cardboard. Packaging disposable paper lunch boxes This coating was used on fabric fibers in the early stage, and then used for the treatment of cardboard. Therefore, most of the tree disposable paper lunch box factories choose the name of water extractor. The water extractor is a wax lotion with a solid content of 48%~51%. It can be diluted with about 30 times water when used.

當遇水時,水在這個紙板上不滋潤,構(gòu)成水滴滾落,從而到達防水的作用。別的因為蠟乳液中蠟的粒徑一般都比一般的高分子乳液粒徑大,要往紙纖維深處浸透也難,一起拔水劑一般對明礬一類化學品靈敏,在紙外表往往很快破乳而沉積下米,因而拔水劑中的蠟粒子絕大部分只在紙面上很薄的一層存在。
When encountering water, the water will not moisturize on the cardboard, forming water droplets rolling down, thus achieving the waterproof effect. In addition, because the particle size of wax in wax lotion is generally larger than that of general polymer lotion, it is also difficult to penetrate into the deep part of paper fiber. Together with the water extractor, it is generally sensitive to alum and other chemicals, and it tends to quickly break the emulsion on the surface of paper and deposit, so most of the wax particles in the water extractor only exist in a thin layer on the paper surface.
