The moisture-proof work of cartons should be done well, otherwise the service life and quality will be affected. Therefore, we still need to pay attention to it. It is very useful to master effective methods of moistureproof.

一种方法可以使用石蜡、微晶蜡、聚乙烯蜡、蜂蜡、白蜡、巴西棕榈蜡、蒙旦蜡等动植物蜡，经乳化后涂于纸板上同样可以防潮与防水，因成本，是目前使用多的办法。

One method can use paraffin wax, microcrystalline wax, polyethylene wax, beeswax, white wax, carnauba wax, montane wax and other animal and plant waxes. After emulsification, they can be applied on paperboard to prevent moisture and water. Because of the low cost, it is the most widely used method at present.

另一种拔水剂是采用三氧化铬在丙醇-盐酸溶液中还原，与硬脂酸配合制成，兼有防霉、防污等特性。目前市场上有不同配方的拔水剂出售。如果将树脂类、淀粉类或胶类防潮剂加入纸浆内抄造成防潮纸，自然对纸箱生产方便，这虽然要增加一些原纸的成本纸箱，纸箱防潮的技巧但总成本还是合算的。

The other one is made by reducing chromium trioxide in propanol hydrochloric acid solution and combining with stearic acid, which has the characteristics of anti mildew and antifouling. At present, there are different formulations of water drawing agents on the market. If the resin, starch or glue moisture-proof agent is added into the pulp to make moisture-proof paper, the production of the paper box is naturally the most convenient. Although it needs to increase the cost of some base paper, the carton moisture-proof skills, but the total cost is still cost-effective.

纸箱工程设计方案如果不合理，没有从工程的实际需求出发，一味的追求纸箱工程标志性效果，就会造成投资的浪费，建筑物的实用率降。

If the design scheme of carton engineering is unreasonable and does not proceed from the actual needs of the project and blindly pursue the symbolic effect of carton engineering, it will cause waste of investment and reduce the practical rate of buildings.

另外，项目决策是纸箱施工的基础，对工程造价起到了决定性的作用，如果没有做好项目的决策对纸箱工程所造成损失是无法估计的。

In addition, project decision-making is the basis of carton construction, which plays a decisive role in the project cost. If the project decision is not made well, the losses caused to the carton project can not be estimated.

影响纸箱决策的因素主要有三方面：

There are three factors that affect the decision-making of cartons

，对设计工作没能引起重视，纸箱施工单位对设计工作也不够细心，没有注意限额的设计；

First, we failed to pay attention to the design work, and the carton construction unit was not careful enough in the design work and did not pay attention to the quota design;

第二，造价人员不了解纸箱纸盒工程的实际情况，考虑的不周全；

Second, the cost personnel do not understand the actual situation of the carton project, and they are not comprehensive;

第三，投资者在招标过程中只注重竞标单位的是否是的，而没有对纸箱施工单位和供应商进行严格的审查，导致在纸箱施工中耗费了很多不必要的费用。

Third, investors only pay attention to whether the price of the bidding unit is the lowest in the bidding process, and do not strictly review the carton construction units and suppliers, resulting in a lot of unnecessary costs in the construction of cartons.
