Phenol resin | Wei Connaught Chemical (certified) | phenol provided by Qingdao Jiaozhou Wei Connaught Chemical Co. Qingdao Wei Connaught Chemical Co. (www.qdweinuo.com) is specialized in the "phenol, aniline, ethylene, n-butanol, isobutanol, n-propanol, isopropanol, methanol," the business, the company adhering to the "integrity management, service intentions, "the idea, to provide you with the highest quality products and services. Welcome to inquire! Contact: Feng Zhongying. Phenol structure and molecular formula: all C atoms are sp2 hybrid orbitals to form σ bond, O atoms are sp2 hybrid orbitals to form σ bond, the remaining p orbital with the benzene ring of large π-conjugated keys. Modern quantum theory and modern testing techniques show: Benzene highly symmetric phenol, 12 atoms in the same plane. Six-membered ring is equilateral; 6 carbon-carbon bond is identical phenol organic solvent, the bond length shorter than the regular one-touch phenol prices, longer than ordinary double bonds. [94.11] relative molecular or atomic weight of phenol: corrosion resistant materials thermosetting phenolic resins commonly used in the field of corrosion in several forms: phenolic resin coating; fiberglass phenolic resin, phenol - epoxy composite fiberglass; phenolic resin mortar, mortar; phenolic resin impregnation, pressure-type graphite products. Thermosetting phenolic resin in solidified form is divided into two kinds of room temperature curing and thermal curing. Room temperature curing can be cured at room temperature using a non-toxic agent NL, can also be used acid chloride or oil, but the latter two materials toxicity, irritation larger. Recommend the use of low toxicity and efficient NL curing agent. Optional graphite packing, ceramic powder, quartz powder, barium sulfate powder, diabase powder should not be used.
