Description

A kind of wet curtain paper and preparation method thereof and the application in transport container
Technical field
Application the present invention relates to a kind of wet curtain paper and preparation method thereof and in transport container.
Background technology
Wet curtain paper, also referred to as cascade paper, shape is honeycomb, is typically processed by body paper, production Flow is about starching, drying, compacting corrugation, sizing, gluing, solidification, slice, reconditioning, de-tastes, the wet curtain paper being prepared With the performance characteristics such as high-hydroscopicity and high intensity, it is the required important composition component of various wet curtain equipment, such as can be used for dropping Warm system, humidification system and filtration system etc..Wet curtain paper usually has tri- kinds of specifications of wave height 5mm, 7mm and 9mm, and ripple is 60 ° × 30 ° it is staggeredly opposed, 45 ° × 45 ° it is staggeredly opposed, there are mainly two types of the wet curtain papers of domestic production, and one is be soaked in using paper It is made after compound, this kind of wet curtain paper is easy to evaporate harmful substance, distribute in air in the process for cooling down or being humidified In, not environmentally, indoor air quality is influenced, and damage health；Another wet curtain paper is made after mostly using log mashing, Water imbibition and tensile resistance are poor, and this kind of method needs a large amount of lumbering, not only breaks up ecological environment and cost is excessively high.Separately Outside, the defects of service life of wet curtain paper is short, and installation is inconvenient, these problems also annoying people.
The prosperity of aquaculture, increasingly improves people's lives.Currently, for the common domestic animal such as such as horse, ox, pig, sheep The transport of poultry, mostly oversize vehicle are transported, and poultry is captured by staff and is positioned in cage or in babinet by hand, is then removed Fortune or other handling appliances are positioned on transport vehicle, are fixed, are carried out unloaded operation after arriving at again.In the transport phase Between, usually protected by grid-like container, this kind of animal avoided to flee, but in practical application it was found that This kind of grid-like container, due to receiving the influence of outdoor temperature, causes inside relatively high, therefore the skill that cools down in summer Art becomes urgent problem to be solved, and one of critical component of container is wet curtain carton, and manufactures the material requirements of wet curtain carton Evaporate large specific surface area, water imbibition are strong, cooling is efficient, drag losses are small, it is dry when not crisp, wet very intensity height, surface spikes it is few, It is not easy that set-off object, easy to clean, service life is long, at low cost, environmentally safe etc., to ensure the normal manufacture of wet curtain carton And product quality, and wet curtain paper is exactly a kind of material of ideal manufacture wet curtain carton, with nontoxic, green, safety, The features such as energy conservation and environmental protection, is applied to the industries such as poultry transporting, animal husbandry, greenhouse, horticulture.
