Fenolic gudurowani abu ne na polymer na roba wanda aka samar ta hanyar damfara na phenols (kamar phenol) da aldehydes (irin su formaldehyde) a ƙarƙashin acid ko tushe catalysis. Yana da kyakkyawan juriya na zafi, rufi da ƙarfin injina kuma ana amfani dashi a cikin lantarki, motoci, sararin samaniya da sauran filayen.
Phenolic guduro (Phenolic Resin) guduro ne na roba wanda aka haɓaka masana'antu. Ana yin ta ta hanyar haɓakar phenol ko abubuwan da suka samo asali (kamar crsol, xylenol) da formaldehyde. Dangane da nau'in mai kara kuzari (acid ko alkaline) da rabon albarkatun kasa, ana iya raba shi zuwa kashi biyu: thermoplastic da thermosetting. "
Babban Halayen Jiki:
1. Yawancin lokaci maras launi ko launin ruwan kasa mai launin ruwan kasa mai haske. Samfuran kasuwanci galibi suna ƙara masu launi don gabatar da launuka iri-iri. "
2. Yana yana da fice zafi juriya da za a iya amfani da dogon lokaci a 180 ℃. Yana samar da babban adadin kuzarin carbon (kimanin 50%) a babban zafin jiki. "
3. Halayen aiki:
Kyakkyawan rufin lantarki, jinkirin harshen wuta (babu buƙatar ƙara masu riƙe wuta) da kwanciyar hankali. "
Yana da babban ƙarfin injina, amma yana da karye kuma yana da sauƙin sha danshi. "
4. Rarrabewa da tsari Thermoplastic phenolic resin: Tsarin layi na layi, yana buƙatar ƙari na wakili mai warkarwa (kamar hexamethylenetetramine) don haɗawa da magani. "
5. ThermosettingPhenol-formaldehyde guduro: Network crosslinking tsarin, za a iya warke ta dumama, yana da mafi girma zafi juriya da inji ƙarfi
An fi amfani da guduro na phenolic don kera robobi daban-daban, kayan shafa, adhesives da zaruruwan roba.
