Q:What is the difference between thermosetting and thermoplastic?
In thermoplastic resins, the molecular chains of resins are linear or branched, with no chemical bonds between the chains, and soften the flow when heated. The process of cooling hardens is a physical change.
Q:The difference between resin sheet and glass sheet
Advantage:1. light weight.2. is not easy to break: if the lens is broken, not only fragments less, and less sharp, can make the eye and facial injuries to a minimum, this is the market marked "safe lenses" the main reason.3., it can be dyed: the resin lens is easy to dye, and can be appropriately matched with the clothes and fashion.4. can block ultraviolet rays: almost completely block ultraviolet wavelengths below 350mm, the effect is far better than glass lenses.5., strong anti fogging: because of the thermal conductivity of resin lens is lower than glass, it is difficult to produce vague and unknown phenomena due to steam and hot water, even if it is blurred, it will soon fade.
Q:How can low molecular polyamide resin be used?
Low molecular polyamide, also called amino polyamide. The molecular weight of 1000~1500, light yellow viscous liquid density (75 C) fand 0.92~0.96g/cm. The amine value is 230~260mg KOH/g. Viscosity (75 DEG C) 3000~1000mPa.s. The composition of low molecular polyamide is complex, containing primary amine, secondary amine and amide group. It can cure epoxy resin at room temperature, and has good adhesion to metal, glass, ceramics, wood and so on. Low molecular polyamide molecules also have a longer aliphatic carbon chain, which can play an internal toughening effect, so that the cured epoxy resin has a certain toughness, therefore, low molecular polyamide is both a curing agent and a toughening agent. Amine value is the indication of low molecular polyamide activity. The higher the amine value is, the greater the activity is, and the reaction speed with epoxy resin is fast, the dosage is little, and the application time is short. Vice versa。
Q:The difference between epoxy resin and plastic
Such as phenolic resin, epoxy resin, unsaturated polyester, etc., thermosetting plastic refers to a specific temperature range can be repeated heating, plasticizing and cooling stereotypes of a plastic. Such as polyethylene, polypropylene, PVC, ABS, nylon, thermoplastic polyester and so on.
Q:What kind of material is the resin made of?
Resin usually refers to softening or melting range after heating. When softening, it tends to flow under external force. At normal temperature, it is solid, semi solid, and sometimes liquid organic polymer. Broadly speaking, any polymer compound that can be used as plastic material for processing raw materials is called resin.
Q:What are the advantages of epoxy resin coatings?
Strong adhesion: the presence of polar hydroxyl groups and ether bonds inherent in the molecular chain of epoxy resins, making it highly adhesive to various substances. When cured, epoxy resin has low shrinkage and little internal stress, which also helps to increase adhesive strength.
Q:Whether you can do pine boards? Is the resin poisonous and how to remove it?
Can do pine boards, but the best material is not cooking plate, because the pine is hard, brittle, when used before processing board.
Q:How about the resin strap?
The strap is more comfortable to wear. But if wet, with some stained plastic or other objects put together, it is contaminated with color, and once it's dyed, it's hard to get out. Therefore, I do not advocate buying white resin strap. I used to have a watch with a white strap and it was dirty a week later. In addition, if the resin strap is not cleaned for a long time, sweat and dust are gathered on it, which will speed up the aging of the strap and cause bacteria to produce odor. Therefore, it is best to buy the anti bacteria, odor watchband (e.g. Casio, G-shock), of course, the price is also more expensive. Also, the resin strap will be aging, and don't let it be exposed to intense sunlight for a long time.
Q:Lighting industry to do the lamp rack, there are many resin materials used, I ask what kind of material in the end, what are the advantages?
Strictly speaking, is a chemical phenolic resin structure, there are many types, widely used in light industry and heavy industry in our daily life, we often come to, such as plastic, resin lenses, coatings, rosin.
Q:How can the resin lenses be repaired?
Upkeep:1, glasses should not be placed in the mirror box, do not contact the outer surface of the lens (external surface) and hard objects.2. Rinse the tap before wiping the lens. If there is oil, you can drop some detergent for washing dishes, then rinse with tap water, and then dry the water with a soft paper towel.3, wipe the lens to use special fiber cloth. If the fabric is dirty, it can be washed and then used.4, coating resin sheet or film universe should beware of high temperature, do not wear glasses to wash a hot bath, not wearing glasses to the sauna; don't put the glasses placed in the summer under the unmanned car; do not put hot air blowing blowing directly into the mirror.
The company has operated a factory producing resin in Wuxi city at its beginning. It developed into the biggest epoxy resin producer in the nation in the early 1980s. It developed the oil refining sector and formed the product pattern of oil products first and chemical products second, which was renamed as Wuxi Petroleum Chemical Factory in the late 1990s. It became a China National BlurStar member company in 1997 under the State-owned Assets Supervision and Administration Commission of the State Council.
