All kinds of sealing tape, transparent tape, packaging tape, bopp tape products，regardless of its type and use, it is made up of three parts: the substrate (rarely the substrate), the pressure sensitive adhesive, the release paper or the separation film. The production process of sealing tape, transparent tape, packaging tape, bopp tape: The pressure-sensitive adhesive is coated on the corona and release agent-treated substrate or temporary carrier by various methods. After drying and curing, the release paper is rewound into a roll (or without the need for direct release of the release paper) , And then cut into products of the specified size and packaged.

September 30, 2017, the 45-days orange war ended, every  partners in this war to pay 100% of the effort, made a different victories, our hunter Legion gains prey 924255.83 dollars, war wolf army prey 402731.1 US dollars, although the end of the war, but we never give up, the spirit of teamwork will always be maintained, let us move forward.

The internal structure of the aqueous acrylic emulsion particles will have an impact on several aspects of the water-based paint formulation. the phase structure will first affect the choice and addition of film forming auxiliaries.Different phases have different hydrophilic / lipophilic characteristics,the lipophilicity of film forming additives is also different.For example, two propylene glycol methyl ether (DPM) is higher hydrophilicity, lower lipophilicity than two propylene glycol butyl ether (DPnB).If the outer layer of the aqueous acrylic emulsion particles is a highly lipophilic phase, the addition of DPM not only affects the film formation, but also allows the excess DPM in water to affect the other properties of the water-based paint film. The other effect of phase structure on the formulation of aqueous coatings is the effect on the film quality of water-based paint film.The key to the quality of the film is in the mixing process of the aqueous acrylic emulsion particles,to allow the mixed phases to be intensively mixied and the separation of the phases to be separated.If different phases are required to participate in the fusion, you should choose a mixed film-forming aid to achieve the best results. Many domestic and foreign literatures on water-based acrylic emulsion polymerization, mentioned the core shell and other emulsion particles structure. Such as core shell, half months, multi-core, hollow, and strawberries and other structures have been reported. The description of these structures is helpful to understand the complexity of the structure of the aqueous acrylic emulsion, but the structure of the water-based acrylic emulsion is much more complicated. For example, only a single phase structure of the particles of the emulsion is not present, the particles in the practical aqueous acrylic emulsion are the distribution of various structures, possibly more core shells, possibly more strawberries, etc. Water-based acrylic emulsion manufacturers control the phase structure of the aqueous acrylic emulsion by the choice of monomer, addition order, surfactant Dosage. The phase structure of the aqueous acrylic emulsion is the technical secret of the emulsion manufacturer, and the information is usually not disclosed. However, supplier will provide its acrylic emulsion recommended additives and proportions . Usually different water-based acrylic emulsion will require different combinations of additives
