Description
Technical field
The present invention relates to making hole film and preparation technology, application and the preparation facilities of a kind of biodegradable.
Background technology
In life, it is frequently used for contacting the hygienic article of health, the most therapeutic medical wound dressings, child
And the diaper of adult and female sanitary towel etc., all must possess absorption liquid, prevent from bleeding back and dry
The function such as refreshing ventilative.Therefore, for reaching above-mentioned functions, it is necessary to by for permeating and the punching bled back being avoided
Film.Traditional making hole film great majority are made up of nondegradable material, and these making hole films use discarded rear difficult
To process, landfill, because of not degrading, causes environmental pollution, burn then produce a large amount of two evils because of, and have poison
Body；It addition, the production of traditional making hole film is all to use post forming to prepare, i.e. the thin film produced
Base material makes film surface soften by the heating system of puncher, and moment utilizes vacuum sucking-off molding, its pass
Depending on pass with drilling forming device, pass through to cut the most again to batch as finished product, this secondary forming process
Suffer from the drawback that power consumption is big, need thin film to be softened vacuum forming again by winding system by heater
Batch；Production capacity is the lowest, wastes the biggest；Operation is loaded down with trivial details；Making hole film product is of poor quality, and it needs at thin film
On the basis of post bake, its product toughness and tensile property after the secondary plasticizing that high temperature produces be deteriorated, hole
The three-dimensional degree of shape is also deteriorated, so the hole shape on thin film can not form funnel-form, easily produces reverse osmosis phenomenon.
In sum, a kind of biodegradable making hole film is prepared in the non-degradable sexual needs for tradition making hole film,
Need to develop preparation facilities and the preparation technology thereof of a kind of biodegradable making hole film, and this system accordingly
Standby device can not only avoid the secondary plasticizing of thin film, and has efficient, energy-conservation performance.
