Titanium dioxide morning tips
1 Rutile type titanium dioxide
As of the close of last Friday, the average price of the sulfuric acid rutile titanium dioxide market assessment is 15683 yuan/ton, the domestic market mainstream negotiation reference 15200-16200 yuan/ton, the mainstream factory in hand orders are okay, coupled with the upstream raw materials expected to be strong, the new single offer to maintain a strong state, the market low price supply reduction.
According to the feedback of manufacturers, the recent mainstream factory new single price, the overall market transaction focus has moved up. On the demand side, the terminal in August is still the off-season, many downstream last month to replenish just need inventory, the current batch purchase intention is limited, the market turnover is low. From the supply side, the mainstream manufacturers still have production reduction or maintenance adjustment inventory in the off-season, and the supply side output is low. Some plastics and papermaking related downstream feedback some models have high prices. Recent titanium dioxide raw material price upward support has been enhanced, comprehensive market factors, the current titanium dioxide market into the stable price state after rising.
2 Anatase titanium dioxide
As of the close of last Friday, the average price of the domestic anatene titanium dioxide market was estimated at 13,000 yuan/ton, and the mainstream reference range for negotiation was mostly centered on 12,500-13,500 yuan/ton. The actual direct selling link price is still more reference in 13,000 yuan/ton. Some lower-priced producers offer even lower prices. On the demand side, because the current price is still relatively low, some downstream bargain purchasing. On the supply side, some manufacturers operate at low load or have maintenance plans. The comprehensive market supply and demand situation and the trend of raw material prices rise, the current market actual transaction price is stable and strong, some manufacturers of titanium diox
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.
Plus, titanium dioxide is chemically inert, meaning it won't react with other substances in the paint. This stability ensures that the paint retains its original color and properties over time, preventing discolouration and degradation. Using titanium dioxide as an ingredient, the paint can withstand harsh weather conditions and prevent flaking, peeling or chalking. This exceptional durability makes it ideal for interior and exterior walls, ensuring a long-lasting and beautiful finish.
