PVA molecules containing a large number of hydroxyl groups, form intra-molecular and intermolecular hydrogen bond, make its melting point close to the decomposition temperature, therefore, the temperature of PVA water soluble film have a significant impact the quality of the charging period of temperature at 134 ºC temperature control effect is better. If the temperature of the compression section is too high, it may cause the decomposition of PV material. If the temperature of the metering section is too high, the melt strength will be easily reduced and it is difficult to form a film. If the temperature is too low, the tube film formed by the annular head is difficult to blow and stretch.
As a temporary carrier, water-soluble PVA film can be used in the production of wigs and embroidery. In terms of embroidery, as the PVA water-soluble film used as the advance payment is water-soluble, it only needs to be soaked in room temperature water for a few minutes, the advance payment material will be completely dissolved, and the embroidery pattern will be presented. Advantages of using water-soluble PVA water-soluble membrane: non-toxic and fully dissolved, easy to handle, no wiredrawing, gluing and other residues; It is suitable for multi-head embroidery machine, without thread breaking and deviation hole. It can be used as a substitute for the non-woven fabric to avoid the textile deformation and the fading of the fiber dye at high temperature.
Made of water soluble PVA water soluble film containing seeds of packing on the belt can be used for planting of crops (e.g., radish, onion, carrot and all kinds of plants, flowers and seeds), so that can improve the efficiency and precision of seeding, and can make the plant according to the seed shape growth will increase with the subnet, can avoid naked seeds in sandstorm area and to blow or let the animals eat, to rain or moisture will water soluble PVA water soluble film dissolve, seed in the soil can sprout.
In the hospital can use high temperature water soluble PVA water soluble film bags will take bacterium contaminated packaging supplies and clothing to the isolation, when cleaning disinfection will directly into the packing bag of pollutant cleaning disinfection equipment in the processing, reduce the medical staff in contact with pollution in the process of transportation, storage and cleaning supplies and clothing, to prevent the spread of germs and prevent secondary infections in hospitals.
To take off the film on
PVA water soluble membrane can be used as an excellent film release agent when parts are made of unsaturated polyester, epoxy resin or other thermosetting resin.
Compared with common packaging materials, the PVA water-soluble film packaging textiles are superior to other packaging materials in terms of its non-static electricity, transparency, glossiness and handfeel, so that the packaging objects present a brighter and cleaner appearance and improve the value of commodities. As PVA water-soluble film has a high barrier to air, it can block the nitrogen of air when used in textile packaging to prevent the textiles from yellowing easily.
Waste packaging of pesticides and fertilizers has become a major public hazard, and PVA water-soluble film packaging bag has been widely used in packaging of pesticides and fertilizers due to its good water solubility and mechanical strength.
Because PVA water-soluble film has a good barrier to gas and oil resistance, these characteristics can make the preservation period of packaged food greatly extended, and can keep its composition and smell intact
Specificationspacking materiala, water soluble bag for Titanium Dioxide packagingPacking material, Water soluble bag for Titanium Dioxide packaging PVA water soluble bag has unique physical property and biodegradability, they have been more and more popularly used in the packaging of cerete additives such as Iron Oxide and Titanium Dioxide packaging Remove the protective outer bag and place the inner water soluble bag into the concrete in the hopper. Turn the agitator to mix the concrete completely for 5-7 minutes. Operation becomes simple and accurate dosage is achieved.The water soluble bag will be dissolved completely leave without any residue. It is safer and more convenient to mix the cement additives without openting the packaging.
