izina RY'IGICURUZWA：resin

Imiterere ya molekulari:

CAS No.:9003-35-4

Imiterere yibicuruzwa：

Ibikoresho bya Shimi:

Fenol-formaldehyde resin yateguwe kuburyo bukurikira:
C6H5OH + H2C = O -> [-C6H2 (OH) CH2-] n
Igice kimwe.Ikigereranyo cya formaldehyde na fenol ni kinini bihagije kugirango inzira ya thermosetting ibeho nta yandi masoko yambukiranya.
Ibyiciro bibiri.Ikigereranyo cya fordehide na fenol ni gito bihagije kugirango wirinde ko thermosetting reaction ibaho mugihe cyo gukora resin.Kuri ubu, resin yitwa novolac resin.Ibikurikira, hexamethylenetetramine yinjizwa mubikoresho kugirango ikore nk'isoko y’imiti ihuza imiti mugihe cyo kubumba (no guhinduka kuri thermoset cyangwa leta yakize).

Gusaba:

Ibisigarira bya fenolike bikoreshwa mubice bidahenze bisaba ibikoresho byiza byamashanyarazi, birwanya ubushyuhe, cyangwa imiti irwanya imiti.Ubuzima bwa tekinike burigihe bwiyi resin ni monthat 1 21.1 ° C.Ibi birashobora kongerwa mukubika firigo ya ina kuri 1,6 kugeza 10 ° C.Guhindura catalizator (ukurikije ubunini bwabakinnyi) no kuzamura ubushyuhe bwo gukiza kugeza kuri 93 ° C bizahindura igihe cyo gukira kuva 8h kugeza kuri 15 min.
Kugabanuka bimwe bibaho muri casting yarangiye (0,012 kugeza 0,6 mm / mm), bitewe nubunini bwuzuye, ingano ya catalizator, hamwe nuburyo bwo gukiza.Inzira yo gukiza byihuse itanga urwego rwo hejuru rwo kugabanuka.Kubera ko inzinguzingo yo gukiza ishobora kwihuta, fenolike ikoreshwa mubikorwa bigufi.
Gutera ibice bya fenolike bivanwa muburyo bworoshye niba ibikoresho byo gutandukana byasabwe nuwabitanze bikoreshwa.Posteuring itezimbere imiterere yibanze ya casting yarangije.
