Phenolic resinchinhu chakagadzirwa nepolymer chinoumbwa nekusanganiswa kwephenols (senge phenol) uye aldehydes (senge formaldehyde) pasi peacid kana base catalysis. Chine simba rakanaka rekudzivirira kupisa, kudzivirira kupisa uye simba remakanika uye chinoshandiswa mumagetsi, mota, ndege nedzimwe nzvimbo.
Phenolic resin (Phenolic Resin) iresini yakagadzirwa yakagadzirwa nemaindasitiri. Inogadzirwa nekuita kwe condensation kwe phenol kana zvinobva mairi (senge cresol, xylenol) uye formaldehyde. Zvichienderana nerudzi rwe catalyst (acidic kana alkaline) uye chiyero chezvinhu zvakagadziriswa, inogona kukamurwa muzvikamu zviviri: thermoplastic uye thermosetting.
Hunhu Hukuru Hunhu hwemuviri:
1. Kazhinji kacho iganda rakasimba risina ruvara kana kuti yero brown rinoonekera. Zvigadzirwa zvinowanikwa muzvitoro zvinowanzoisa mavara akasiyana-siyana.
2. Inodzivirira kupisa zvakanyanya uye inogona kushandiswa kwenguva yakareba pa180℃. Inogadzira kabhoni yakawanda inosara (inenge 50%) pakupisa kwakanyanya.
3. Hunhu hwekushanda:
Kudzivirira moto zvakanaka, kunonoka moto (hapana chikonzero chekuwedzera zvinodzivisa moto) uye kugadzikana kwehukuru hwayo.
Ine simba guru remuchina, asi inopfava uye iri nyore kunyudza hunyoro.
4. Kupatsanura uye chimiro Thermoplastic phenolic resin : Chimiro chakatsetseka, chinoda kuwedzerwa kwechinhu chinoporesa (senge hexamethylenetetramine) kune crosslink uye cure.
5. Kugadzirisa ThermostatPhenol-formaldehyde resin: Chimiro chekubatanidza network, chinogona kurapwa nekupisa, chinodzivirira kupisa zvakanyanya uye chine simba remakanika
Phenolic resin inonyanya kushandiswa kugadzira mapurasitiki akasiyana-siyana, machira, manamatisi uye mafiber ekugadzira.
