Abstract
The invention discloses a kind of novel compound cement packaging bag, including outer packaging bag and inner lining bag, inner lining bag is water-soluble poval (PVA) film.Outer packaging bag is the sack of Polywoven Bag or kraft paper bag or other materials production, also steel band the tape casting, melting extrusion blow moulding, heat can be used to melt the polyvinyl alcohol series film that the processes such as the tape casting are produced for the PVA film that water-soluble poval (PVA) film is preferentially produced using solution casting method.After new type cement packing bag of the invention, it can the various environment of the current conventional plastic woven bags packaging cement bring of effective solution and health problem, cement highly efficient can be utilized, packing material is remained without cement, and partial wrapper can be realized repeatedly or be recycled.
Description
Technical field
The invention belongs to cement package bags fields, and in particular to a kind of novel compound cement packaging bag.
Background technique
Cement, i.e. powdery hydraulicity inorganic coagulation material.At slurry after adding water and stirring, can harden in air or in water
In preferably harden, and can the materials such as sand, stone are cemented together securely.
Currently, China's cement mostly uses Polywoven Bag to pack or using large-scale filling bucket, using Polywoven Bag
Packaging is the Traditional Packing mode of cement, technology maturation remote using the time, the relatively inexpensive material benefit of packing cost, but is taken
The protrusion of defect present in the manner of packing also more.The technology for woven plastic packing bag of cement is disposable, and cement
Residual quantity is big, it is difficult to it recycles, and evil mind businessman recycles cement package bags there are many country, it is secondary by washing for several times
Plastic grain is processed, brings the right people of huge environmental pollution to make us startling surrounding water and environment；Secondly because braiding
Bag sealing performance is poor, and cement granules partial size is small, has a large amount of cement during transport is with handling and leaks, leaks out
Cement brings huge threat to the health of stevedore, and the worker for being engaged in cement handling throughout the year can have different journeys substantially
The pneumoconiosis occupational disease of degree.
Summary of the invention
In view of the deficienciess of the prior art, the present invention provides a kind of novel compound cement packaging bag.
A kind of novel compound cement packaging bag, including outer packaging bag and inner lining bag, inner lining bag are water-soluble poval
(PVA) film.
Outer packaging bag is the sack of Polywoven Bag or kraft paper bag or other materials production
Steel band also can be used in the PVA film that water-soluble poval (PVA) film is preferentially produced using solution casting method
The tape casting, melting extrusion blow moulding, heat melt the polyvinyl alcohol series film that the processes such as the tape casting are produced.
Compared with prior art, the beneficial effects of the present invention are: inner lining bag of the invention uses water-soluble poval
(PVA) film, the characteristic which has cold water water-soluble, in use, cement is packed into inner lining bag, inner lining bag is in the effective of outer packing
Protection is not lower certifiable damaged in transit, and cement will not leak under the protection of liner, will not also generate dust etc.
Pollution, PVA film can also play the role of enhancing cement after being dissolved in water, and the substantially anhydrous mud residual of outer packing also can be recycled
It reuses, to greatly reduce contact of the construction worker with cement dust, effectively protects the physical and mental health of construction worker.
It, can the current conventional plastic woven bags packaging cement band of effective solution after the new type cement packing bag of the invention
The various environment and health problem come, can utilize cement highly efficient, and packing material is remained without cement, and partial wrapper can be realized
Repeatedly or recycle.
Detailed description of the invention
Fig. 1 is structure chart of the invention.
In attached drawing: 1. outer packaging bags；2. inner lining bag；Water-soluble poval 3. (PVA) film.
Specific embodiment
The embodiment of the present invention is described in detail below in conjunction with attached drawing, but the present invention can be defined by the claims
Implement with the multitude of different ways of covering.
Embodiment 1
A kind of novel compound cement packaging bag, including outer packaging bag 1 and inner lining bag 2, outer packaging bag 1 is Polywoven Bag,
The effect that cement is protected and carried to inner lining bag 2 is primarily served, inner lining bag 2 is water-soluble poval (PVA) film 3, preferentially
The PVA film produced using solution casting method also steel band the tape casting, melting extrusion blow moulding, heat can be used to melt the tape casting etc.
The polyvinyl alcohol series film that process is produced, cement are packed into inner lining bag 2, when in use since inner lining bag 2 has cold water
Water solubility directly opens outer packaging bag 1, in the whole packet cement investment blender that inner lining bag 2 is packed.
Embodiment 2
Including outer packaging bag 1 and inner lining bag 2, outer packaging bag 1 is kraft paper bag, primarily serves and inner lining bag 2 is protected and held
The effect of cement is carried, inner lining bag 2 is water-soluble poval (PVA) film 3, the preferential PVA produced using solution casting method
Also steel band the tape casting, melting extrusion blow moulding, heat can be used to melt the polyethenol series that the processes such as the tape casting are produced for film
Column film, cement are packed into inner lining bag 2, when in use since inner lining bag 2 has cold water water-soluble, directly open outer packaging bag 1,
In the whole packet cement investment blender that inner lining bag 2 is packed.
In conclusion being only the preferred embodiment of invention, not it is used to limit the scope of implementation of the present invention, Fan Yiben
Equivalent changes and modifications carried out by shape described in invention scope of the claims, construction, feature and spirit, should be included in this hair
In bright scope of the claims.
