Resinosetting resin ni iki?
Ubushuhe bwa Thermosetting resin cyangwa thermosetting resin ni polymer yakize cyangwa ikozwe muburyo bukomeye ukoresheje uburyo bwo gukiza nko gushyushya cyangwa imirasire.Inzira yo gukiza ni inzira idasubirwaho.Ihuza umuyoboro wa polymer unyuze mumashanyarazi ya covalent.
Nyuma yo gushyushya, ibikoresho bya termosetting bikomeza gukomera kugeza igihe ubushyuhe bugera ku bushyuhe butangiye kwangirika.Ubu buryo butandukanye nubwa plastiki ya termoplastique.Ingero nyinshi za resmosetting resin ni:
Fenolike
- Amino resin
- Polyester resin
- Silicone
- Epoxy resin, na
- Polyurethane
Muri byo, epoxy resin cyangwa fenolike resin ni imwe mu mikorere ya termosetting.Muri iki gihe, zikoreshwa cyane muburyo bwihariye kandi bwihariye bukoreshwa.Bitewe n'imbaraga zabo nyinshi no gukomera (bitewe no guhuza kwinshi), birakwiriye kubisabwa byose.
Ni ubuhe bwoko bw'ingenzi bwa epoxy resin ikoreshwa mubikoresho byinshi?
Ubwoko butatu bwingenzi bwa epoxy resin ikoreshwa mubikoresho bifatika ni:
- Fenolike aldehyde glycidyl ether
- Aromatic glycidyl amine
- Inzira ya alifatique
Nibihe bintu byingenzi biranga epoxy resin?
Twashyize kurutonde hepfo ibintu byingenzi bitangwa na epoxy resin.
- Imbaraga nyinshi
- Igipimo gito cyo kugabanuka
- Ifite neza neza kubutaka butandukanye
- Gukoresha amashanyarazi neza
- Kurwanya imiti no kurwanya ibishishwa, kimwe
- Igiciro gito n'uburozi buke
Epoxy resin iroroshye gukira kandi irahujwe na substrate nyinshi.Biroroshye guhanagura hejuru kandi birakwiriye cyane cyane kubintu bifatika.Epoxy resin nayo ikoreshwa muguhindura polymers nyinshi, nka polyurethane cyangwa polyester idahagije.Bongera imiterere yumubiri nubumara.Kuri thermosetting epoxy resins:
- Imbaraga zingana zingana kuva kuri 90 kugeza 120MPa
- Urutonde rwa tensile modulus ni 3100 kugeza 3800MPa
- Ubushyuhe bwikirahure (Tg) buringaniye ni 150 kugeza 220 ° C.
Epoxy resin ifite ibibi bibiri by'ingenzi, aribyo ubwitonzi bwayo hamwe no kumva amazi.
