Chemical Properties:

Phenol-formaldehyde resin inogadzirwa nenzira inotevera:
C6H5OH+H2C=O —> [-C6H2(OH)CH2-]n
Imwe-Stage Resins.Chiyero che formaldehyde kune phenol chakakwira zvakakwana kubvumira iyo thermosetting process kuti iitike pasina kuwedzera kwemamwe masosi e-cross-link.
Matanho maviri Resins.Huyero ye formaldehyde kune phenol yakadzikira zvakakwana kudzivirira iyo thermosetting reaction kubva kuitika panguva yekugadzirwa kweresin.Panguva iyi resin inonzi novolac resin.Zvadaro, hexamethylenetetramine inobatanidzwa mune zvinyorwa kuti iite sechitubu chemakemikari e-cross-link panguva yekuumbwa kwekushanda (uye kutendeuka kune thermoset kana kuporesa nyika).

Application:

Phenolic resins inoshandiswa kune yakaderera-mutengo zvikamu zvinoda yakanaka magetsi insulating zvivakwa, kupisa kupisa, kana makemikari kuramba.Avhareji yehupenyu hwesherufu yeresin iyi ingangoita mwedzi mumwe pa21.1°C.Izvi zvinogona kuwedzerwa nekuichengeta mufiriji pa1.6 kusvika 10°C.Kusiyanisa iyo catalyst (maererano nehukobvu hwekukandira) uye kukwidza tembiricha yekurapa kusvika 93 ° C kuchachinja nguva yekurapa kubva kureba se8h kusvika kupfupi se15 min.
Imwe shrinkage inoitika mukukandwa kwakapedzwa (0.012 kusvika 0.6 mm/mm), zvichienderana nehuwandu hwekuzadza, huwandu hwezvinokonzeresa, uye chiyero chekurapa.Kurumidza kurapa kutenderera kunounza mwero wepamusoro we shrinkage.Sezvo kutenderera kwekurapa kunogona kukwidziridzwa, phenolics anoshandiswa mukupfupi-runcasting mashandiro.
Cast phenolic zvikamu zvinobviswa zviri nyore kubva muforoma kana maajenti ekuparadzanisa anokurudzirwa nemupi akashandiswa.Posteuring inovandudza thebasic zvimiro zvekupedzwa kukanda.
