PBT-LGF Polybutanediol terephthalate (PBT) has excellent comprehensive properties, such as high crystallinity, rapid prototyping, weather resistance, low friction coefficient, high thermal deformation temperature, good electrical properties, excellent mechanical properties, fatigue resistance, can be ultrasonic welding. However, its notched impact strength is low, forming shrinkage rate is large, hydrolysis resistance is poor, easy to be eroded by halogenated hydrocarbons, after glass fiber reinforcement, because of the product longitudinal and horizontal shrinkage is inconsistent easy to warping products. With its excellent comprehensive performance, PBT is widely used in electronic and electrical appliances, automobile industry, machinery, instruments and household appliances and other fields. Common problem & Solvement Glass fiber reinforced PBT material warps easily Reasons: Warping is the result of uneven shrinkage of the material. The warping of the product can be caused by the orientation and crystallization of the components in the material, the improper technological conditions used in the injection molding, the wrong shape and position of the gate in the mold design, and the uneven thickness of the wall in the product design. The warping of PBT/GF composites is mainly due to the fact that the orientation of the glass fiber in the flow direction restricts the shrinkage of the resin, and the induced crystallization of PBT around the glass fiber strengthens this effect, making the longitudinal (flow direction) shrinkage of the product less than the transverse (perpendicular to the flow direction). This uneven shrinkage leads to the warping of PBT/GF composites. Solution: 1. Add minerals and use the shape symmetry of mineral fillers to reduce the anisotropy caused by the glass fiber orientation; 2. Add amorphous materials to reduce the crystallinity of PBT and reduce the uneven shrinkage caused by crystallization, such AS ASA or AS, but they have poor compatibility with PBT, so appropriate compatibilizers need to be added; 3. Adjust injection molding process, such as increasing mold temperature and increasing injection cycle appropriately. Glass fiber reinforced PBT surface floating fiber problem Reasons: The causes of floating fiber are more complex, in short, there are mainly the following aspects 1. The compatibility of PBT and glass fiber is very poor, resulting in the two can not effectively bond together; 2. The viscosity of PBT and glass fiber is very different, resulting in a tendency of separation between the two in the flow process. When the separation effect is greater than the adhesive force, the separation will occur, and the glass fiber will float to the outer layer and leak out; 3. The existence of shear force will not only lead to local viscosity differences, but also destroy the interface layer melt viscosity on the glass fiber surface, the smaller the interface layer is damaged, the smaller the bonding force on the glass fiber. When the viscosity is low to a certain degree, the glass fiber will get rid of the PBT resin matrix and gradually accumulate to the surface and expose. 4. Influence of mold temperature. Due to the low temperature of the mold surface, the glass fiber with light weight and fast condensation is frozen instantaneously. If it is not fully surrounded by melt in time, it will be exposed and form "floating fiber". Solution: 1) Add compatibilizers, dispersants and lubricants to improve the floating fiber problem. For example, the use of special surface treatment of glass fiber, or adding compatibilizers (such as: SOG, a well-flowing PBT modified compatibilizer) through the "bridge" effect, increase the adhesion of PBT and glass fiber. 2) Optimize the molding process to improve the floating fiber problem. Higher injection molding temperature and mold temperature, larger injection molding pressure and back pressure, faster injection molding speed, lower screw speed, can improve the floating fiber problem to a certain extent. The glass fiber reinforced PBT injection molding process is easy to produce more mold scale Reasons: The formation of mold scale is caused by the high content of small molecules or the poor thermal stability of materials. Compared with other materials, PBT is easy to generate mold scale due to its oligomer and small molecule residue rate usually in the range of 1%-3%. And after the introduction of glass fiber, more obvious. This will lead to the continuous processing process, the need to clean the mold regularly, resulting in low production efficiency. Solution: 1) Reduce the amount of small molecule additives (such as lubricant, coupling agent, etc.), try to choose polymer additives; 2) Melhorar a estabilidade térmica do PBT e reduzir os pequenos produtos moleculares produzidos pela degradação térmica durante o processamento; Aplicação PBT Amplamente utilizado em máquinas, eletrônicos e elétricos, indústria automotiva e eletrodomésticos e outros...

informações PPS A matriz resinosa dos compósitos termoplásticos envolve plásticos de engenharia em geral e especiais, sendo o PPS um representante típico dos plásticos de engenharia especiais, comumente conhecidos como "plástico ouro". As vantagens de desempenho incluem os seguintes aspectos: excelente resistência ao calor, boas propriedades mecânicas, resistência à corrosão, retardador de chama até o nível UL94 V-0. Porque PPS tem as vantagens das propriedades acima, e em comparação com outros plásticos de engenharia termoplásticos de alto desempenho e tem as características de fácil processamento, baixo custo, tornando-se uma excelente matriz de resina para a fabricação de materiais compósitos. Material composto PPS O material composto de fibra de vidro curta (SGF) de enchimento PPS tem as vantagens de alta resistência, alta resistência ao calor, retardador de chama, fácil processamento, baixo custo e tem sido aplicado em automotivo, eletrônicos, elétricos, máquinas, instrumentos, aviação, aeroespacial, militar e outros campos. O material composto de fibra de vidro longa (LGF) de enchimento PPS tem as vantagens de alta tenacidade, baixa deformação, resistência à fadiga, boa aparência do produto e assim por diante. Pode ser usado no impulsor do aquecedor de água, carcaça da bomba, junta, válvula, impulsor e carcaça da bomba química, rotor e carcaça da água de resfriamento, peças de eletrodomésticos e assim por diante. Quais são as diferenças específicas entre os compósitos PPS reforçados com fibra de vidro curta (SGF) e com fibra de vidro longa (LGF)? 1.  Análise de propriedades mecânicas The reinforcement fiber added in the resin matrix can form a supporting skeleton, and the reinforcement fiber can effectively bear the external load when the composite is subjected to external force. At the same time, energy can be absorbed by fracture, deformation and other ways to improve the mechanical properties of resin. The tensile strength and bending strength of the composites are gradually increased by increasing the amount of glass fiber. The main reason is that when the glass fiber content increases, more glass fiber in the composite material can withstand the action of external force. Meanwhile, due to the increase in the number of glass fibers, the resin matrix between the glass fibers becomes thinner, which is more conducive to the construction of glass fiber reinforced frame. Therefore, with the increase of glass fiber content, more stress is transferred from resin to glass fiber under external load, which effectively improves the tensile and bending properties of composite materials. The tensile and bending properties of PPS/LGF composites are higher than those of PPS/SGF composites. When the glass fiber mass fraction is 30%, the tensile strength of PPS/SGF and PPS/LGF composites is 110MPa and 122MPa, respectively. The bending strength was 175MPa and 208MPa, respectively. The flexural elastic modulus were 8GPa and 9GPa, respectively. The tensile strength, bending strength and bending elastic modulus of PPS/LGF composites are increased by 11.0%, 18.9% and 11.3% compared with PPS/SGF composites, respectively. PPS/LGF composites have higher length retention rate of glass fiber. Under the condition of the same glass fiber content, the composites have stronger load resistance and better mechanical properties. When the glass fiber content is low, the impact strength of the composite decreases. The main reason is that the lower glass fiber content cannot form a good stress transfer network in the composite material, so that the glass fiber exists in the form of defects under the impact load of the composite material, resulting in the overall impact strength of the composite material is reduced. With the increase of the glass fiber content, the glass fiber in the composite can form an effective spatial network, and the reinforcement effect is greater than that of the glass fiber tip. Under the action of external load, the external load can be transferred to the reinforced fiber better, thus improving the overall performance of the composite. In the PPS/LGF system, the length of the glass fiber is longer and the spatial network is more dense. The reinforced glass fiber has greater bearing capacity and better impact strength. When the mass fraction of glass fiber is 30%, the impact strength of PPS/LGF is increased by 19.4% from 31kJ/m2 to 37kJ/m2, and the notch impact strength is increased by 54.5%(from 7.7kJ/m2 to 11.9kJ/m2). 2. Thermal properties analysis of PPS/SGF and PPS/LGF composites When the mass fraction of glass fiber is 30%, the thermal deformation temperature of PPS/SGF composite and PPS/LGF composite reaches 250℃ and 275℃, respectively. The thermal deformation temperature of PPS/LGF composite is 10% higher than that of PPS/SGF composite. The main reason is that the introduction of glass fiber makes the network skeleton of reinforced fiber formed inside the composite material, which greatly imp...
