It can be used as the main catalyst for the preparation of flexible polyurethane foams. It is also a co-catalyst for the preparation of semi-rigid and rigid polyurethane foams.

3. The "5pc additive" you call is most likely PC-5 additive. Its chemical name is pentamethyldiethylenetriamine, and its English abbreviation is PMDETA.

4. Main uses: Production of rigid polyurethane foams: It is a tertiary amine catalyst commonly used in rigid polyurethane foams. It mainly promotes the reaction of isocyanate (MDI or TDI) and water to form carbon dioxide to form a foam structure. It is often used in conjunction with catalysts such as DMCHA. The addition amount is usually 0-0 parts per 100 parts of polyol.

5. -pc additive usually refers to the polyurethane catalyst PC5. Its professional name is pentamethyldiethylenetriamine, and its chemical name is N, N, N', N ", N"-pentamethyldiethylenetriamine. The English name of the substance is Pentamethyldiethylenetriamine, CAS number is 3030-47-5, and molecular formula is CHN. It belongs to a highly active tertiary amine catalyst for polyurethane reaction. It has a colorless to light yellow transparent liquid and is easily soluble in water. It is widely used in the production of polyurethane hard and soft foams.

Partial discharge of transformers, what does 5pc mean

Partial discharge in transformer is a discharge phenomenon that occurs in the internal insulation of a transformer under the action of high voltage and is limited to local locations of the insulation. Definition of partial discharge Partial discharge is mainly the discharge that occurs in the internal insulation of transformers, transformers and other high-voltage electrical equipment under the action of high voltage. This kind of discharge only exists in a local location of the insulation and does not immediately form a penetration breakdown or flashover of the entire insulation, so it is called a partial discharge.

Dust control: Foreign matter and dust are important factors in local discharges. Metal particles can produce discharges much greater than 500pC under the action of an electric field. During the manufacturing process of transformers, the environment and the body must be kept clean, and dust control must be strictly implemented. Establish a sealed and dustproof workshop to ensure that no foreign matter residue and dust are allowed to enter during wire leveling, winding, winding groups, core stacking, insulation manufacturing, body assembly and body trimming.

Partial discharge of 10PC is the amount of partial discharge. Discharge occurs only in local areas of the insulator, but does not penetrate between the conductors to which voltage is applied. It can occur near the conductors or in other places. This phenomenon is called partial discharge. Electrical equipment insulation is a local discharge occurring under the action of a sufficiently strong electric field. This discharge is limited to causing only local short insulation (bridge and bridge) connections between conductors without forming conductive channels.

4. The design of the mask is mostly five-piece per box, which is mainly related to sales convenience, cost control, transportation efficiency and beauty effect planning. The specific reasons are as follows: The convenience of sales of five-piece or ten-piece packs is the market-verified "golden quantity". This specification can not only meet the needs of consumers for multiple uses (such as 1-2 times a week, five tablets can cover 3-4 weeks), but also avoid the waste that may be caused by single purchase or oversized packaging (such as 20 tablets). Price sensitive issues.
