Phenolic resinis a synthetic polymer material inoumbwa ne condensation ye phenols (yakadai se phenol) uye aldehydes (yakadai se formaldehyde) pasi peasidhi kana base catalysis. Iyo ine yakanakisa kupisa kupisa, insulation uye simba remagetsi uye inoshandiswa mumagetsi, mota, aerospace uye mamwe minda.
Phenolic resin (Phenolic Resin) is a synthetic resin yakagadziridzwa. Iyo inogadzirwa neiyo condensation reaction ye phenol kana mhedzisiro yayo (senge cresol, xylenol) uye formaldehyde. Zvinoenderana nerudzi rwecatalyst (acidic kana alkaline) uye chiyero chemidziyo, inogona kukamurwa muzvikamu zviviri: thermoplastic uye thermosetting. .
Hunhu Hunhu Hwemuviri:
1. Inowanzova isina ruvara kana yero yebrown inoonekera. Zvigadzirwa zvinowanikwa mune zvekutengesa zvinowanzowedzera mavara ekupa mavara akasiyana. .
2. Iyo ine yakasarudzika kupisa kusagadzikana uye inogona kushandiswa kwenguva yakareba pa180 ℃. Inoumba yakakwira yakasara kabhoni rate (inenge 50%) pakupisa kwakanyanya. .
3. Functional characters:
Yakanakisa magetsi ekudzivirira, kudzoreredza kwemurazvo (hapana chikonzero chekuwedzera zvinodzosa moto) uye kugadzikana kwedimensional. .
Iyo ine yakakwira mechanical simba, asi ine brittle uye iri nyore kutora unyoro. .
4. Kuronga uye chimiro Thermoplastic phenolic resin : Linear structure, inoda kuwedzerwa mushonga wekurapa (wakadai sehexamethylenetetramine) kuyambuka uye kurapa. .
5. ThermosettingPhenol-formaldehyde resin: Network crosslinking chimiro, inogona kurapwa nekudziya, ine yakanyanya kupisa kupisa uye simba remuchina
Phenolic resin inonyanya kushandiswa kugadzira mapurasitiki akasiyana-siyana, machira, zvinonamira uye mafibhi ekugadzira.
