Pure PVB is non-toxic and harmless to human body. In addition, ethyl acetate or alcohol can be used as solvent, so PVB is widely used in printing ink of food containers and plastic packaging in European and American countries.

Storage safety properties

PVB can be stored for two years without affecting its quality as long as it is not in direct contact with water; PVB shall be stored in a dry and cool place and avoid direct sunlight. Heavy pressure shall be avoided during PVB storage.

Solubility

PVB is soluble in alcohol, ketone, ester and other solvents. The solubility of various solvents changes according to the functional group composition of PVB itself. Generally speaking, alcohol solvents are soluble, but methanol is more insoluble for those with high acetal groups; The higher the acetal group, the easier it is to dissolve in ketone solvents and ester solvents;

PVB is easily soluble in cellosolve solvents; PVB is only partially dissolved in aromatic solvents such as xylene and toluene; PVB is insoluble in hydrocarbon solvents.

Viscosity characteristics of PVB solution

The viscosity of PVB solution is greatly affected by the formula of solvent and the type of solvent; Generally speaking, if alcohol is used as solvent, the higher the molecular weight of alcohol, the higher the viscosity of PVB solution;

Aromatic solvents such as xylene and toluene and hydrocarbon solvents can be used as diluents to reduce the viscosity of PVB solution; The effect of PVB chemical composition on viscosity is summarized as follows: under the same solvent and the same content of each base, the higher the degree of polymerization, the higher the solution viscosity; Under the same solvent and the same degree of polymerization, the higher the acetal group or acetate group, the lower the solution viscosity.

Dissolution method of PVB

Where mixed solvents are used, the dissolution step is to first put aromatic solvents (such as xylene, toluene, etc.) or ester solvents (such as n-butyl acetate, ethyl acetate, etc.) into the mixing, slowly put PVB into the mixing, and then add alcohol solvents (such as n-butanol, ethanol, etc.) after PVB is dispersed and expanded,

At this time, the dissolution time can be shortened by heating; Using this dissolution method, the formation of lumpy PVB can be avoided (because the dissolution time will be several times after the formation of lumpy PVB), so the dissolution speed can be accelerated. Generally, the ratio of aromatic and alcohol solvents is 60 / 40 ~ 40 / 60 (weight ratio), and PVB solution with low viscosity can be prepared.

The solvent composition contains 2 ~ 3wt% water, which can improve the hydrogen bonding strength of alcohol solvents and help the solubility of PVB.

Processing properties

Although PVB resin is a thermoplastic, it has little processability before plasticizer is added. Once plasticizer is added, its processability is very easy.

The purpose of general coatings and adhesives is to change the resin characteristics by adding plasticizers to meet the application requirements, such as film softness, reducing the TG point of the resin, reducing the heat sealing temperature, maintaining low-temperature softness, etc.

Compatibility

PVB can be compatible with a variety of resins, such as phenolic resin, epoxy resin, alkyd resin and MELAMINE resin.

B-08sy, b-06sy and b-05sy with high acetal degree can be mixed with nitrocellulose in any proportion. PVB and alkyd resin are partially compatible. General PVB is compatible with low molecular weight epoxy resin, while high molecular weight epoxy resin needs PVB with high acetal degree to be compatible with each other.

  • The Significance of Bed Sheets in Hospitals A Seamless Blend of Comfort and Hygiene In the intricate tapestry of healthcare, the humble bed sheet holds an often-overlooked yet crucial role. The bed sheet, more than just a piece of fabric, is a significant element in hospital settings, contributing to patient comfort, hygiene, and even recovery. Hospital bed sheets, typically made from high-quality, durable materials like cotton or a blend of cotton and polyester, are designed with functionality in mind. They are chosen for their ability to withstand frequent washing and sterilization, which is paramount in a medical environment where infection control is a top priority. The inclusion of '20' here refers to the thread count, a measure of the density and quality of the fabric. Higher thread counts often equate to softer, more comfortable sheets, providing a sense of home-like comfort to patients amidst the clinical surroundings. Beyond the physical attributes, bed sheets in hospitals serve as a vital tool in maintaining hygiene. Regular changing and laundering of these sheets not only prevent the spread of germs but also contribute to the psychological well-being of patients. A clean and fresh bed promotes a sense of cleanliness and reduces anxiety, thereby fostering a healing environment. Moreover, the color and design of hospital bed sheets can have a therapeutic effect. Neutral shades like white or light blue are commonly used, known for their calming properties, helping to create a soothing atmosphere for patients Neutral shades like white or light blue are commonly used, known for their calming properties, helping to create a soothing atmosphere for patients Neutral shades like white or light blue are commonly used, known for their calming properties, helping to create a soothing atmosphere for patients Neutral shades like white or light blue are commonly used, known for their calming properties, helping to create a soothing atmosphere for patientsbed sheet in hospital. In some instances, patterned or colored sheets might be used for dementia patients, as they can stimulate memory and orientation. The role of bed sheets extends beyond the patient's bedside. They are also instrumental in medical procedures, serving as a barrier during surgeries or as a means to position patients for exams or treatments. The 'bed sheet' also plays a role in communication between medical staff, with certain sheet positions indicating a patient's status or need for attention. In conclusion, the seemingly insignificant bed sheet in a hospital is a microcosm of the broader healthcare system. It is a symbol of cleanliness, comfort, and care, silently contributing to the healing process. Its importance goes beyond its physical function, touching upon the emotional and psychological aspects of patient care. Thus, the next time you encounter a hospital bed sheet, remember the vital role it plays in the journey towards recovery.
