Ethyl selile (Ethyl selile ether), uzwi kandi nka selile, bivugwa nka EC.
Ibigize molekosulation hamwe na formula yubaka: [C6H7O2 (OC2H5) 3] n.
1.Gukoresha
This product has the functions of bonding, filling, film forming, etc. It is used for resin synthetic plastics, coatings, rubber substitutes, inks, insulating materials, and also used as adhesives, textile finishing agents, etc., and can be used as animal in agriculture and animal husbandry Feed additive, used as adhesive in electronic products and military propellants.
2. Ibisabwa bya tekiniki
Dukurikije uburyo butandukanye, EC yubucuruzi irashobora kugabanywamo ibyiciro bibiri: Icyiciro cyinganda hamwe nicyiciro cya farumasi, kandi muri rusange bishonga mubintu byamarika. Ku cyiciro cya farumasi ec, ubuziranenge bwayo bugomba kuzuza ibipimo bya farumacopopoeia 2000
3.. Umubiri na shimi
1. Kugaragara: EC ifite ifu yera cyangwa yoroheje yamazi meza, impumuro.
2. Ibyiza: EC yubucuruzi muri rusange idahujwe mumazi, ariko ndumiwe mubintu bitandukanye. Ifite ubushyuhe bwiza bwumuriro, ivu cyane ivu cyane iyo yatwitse, kandi gake irakomera cyangwa yumva ashikamye. Irashobora gukora firime itoroshye. Irashobora gukomeza guhinduka. Iki gicuruzwa ntabwo ari uburozi, gifite imitungo ikomeye yo kurwanya ibinyabuzima, kandi ifite inert induru, ariko ikunda kwangirika kwa okiside munsi yumucyo cyangwa ultraviolet. Kubwintego idasanzwe EC, hari nubwoko ishonga mumazi n'amazi meza. Kuri EC hamwe nurwego rwo gusimbuza hejuru ya 1.5, ni thermoplastique, hamwe na sofpesting ya 135 ~ 155 ° C, ingingo ishonga 165 ~ 185 G / CM3, hamwe nubucucike bwa 1.07 ~ 1.18 G / CM3. Urwego rwo Gutsindira EC rugira ingaruka ku buke, kwinjiza amazi, imitungo ya mashini n'imitungo itimukanwa. Mugihe urwego rwo guhitamo rwiyongera, kwikeba muburyo bwa Lye bigabanuka, mugihe umukecuru mubikemuro byiyongera. Gushonga mubintu byinshi bya kama. Mubisanzwe byakoreshejwe poliven ni Toluene / Ethanol nka 1/1 (uburemere) bivanze na solive. Urwego rwo Gutsimbataza rwiyongera, ingingo yoroshye hamwe ninyamanswa igabanuka, kandi ubushyuhe bwambere ni -60 ° C ~ 85 ° c. Imbaraga za Tensile 13,7 ~ 54.9MPA, Kurwanya ingano 10 * E12 ~ 10 * E14 ω.cm
Ethyl selile (DS: 2.3-2.6) ni selile itari ionic ether idahujwe mumazi ariko ashonga mubi.
1.Ntabwo byoroshye gutwika.
2. Ihungabana ryumuhanda hamwe na THERMOS nziza-plastike.
3.Ntugahindure ibara ku zuba.
4.Ibyo byoroshye guhinduka.
5.Amapfumu.
6.Bifite kurwanya neza alkali no kurwanya acide.
7.Gukora ibikorwa byo kurwanya.
8. Guhindura Umunyu, kurwanya ubukonje nubushuhe byibasiye.
9.Bit ihamye imiti kandi ntishobora kwangirika mububiko bwigihe kirekire.
10.Birashobora guhuza nibisohoka byinshi kandi bifite akamaro keza na plastistizers yose.
11.Biroroshye guhindura ibara mugikorwa gikomeye cya alkaline nubushyuhe.
4. Uburyo bwo kuvugurura
Igipimo gikunze gukoreshwa kuvanga ibyuma bya Ethyl Cellulose (DS: 2.3 ~ 2.6) ni hydrocarbone na alcool. Impungenga irashobora kuba benzene, Toluene, Ethylbenzene, Xylene, nibindi, hamwe na 60-80%; Inzoga zirashobora kuba methanol, Ethanol, nibindi, hamwe na 20-40%. Buhoro buhoro ongeraho EC kuri kontineri ikubiyemo igisubizo kirimo gukangurira kugeza kirimo rwose kandi gishonga.
CAS OYA .: 9004-57-3
5. Gusaba
Kubera amazi yacyo ihutse, Ethyl selile ikoreshwa cyane nkibikoresho binini hamwe nibikoresho byo guhinga rya firime, nibindi, kandi birashobora kandi gukoreshwa nkabakiriya ba Matrix kugirango bategure ubwoko butandukanye bwa Matrix harakomeje ibinini bya Matrix.
Ikoreshwa nkibikoresho bivanze kugirango witegure inkomoko ikomeje-kurekura no gukomera-kurekura pellet;
Ikoreshwa nkibikoresho byingirakamaro kugirango bitegure microcapsules irakomeza, kugirango ingaruka zibi zishobore kurekurwa ubudahwema kandi zibuza ibiyobyabwenge bidasubirwaho byamazi gutanga neza;
Irashobora kandi gukoreshwa nkuwatatanye, stabilizer, kandi ugumana amazi, hamwe namazi mumpapuro zinyuranye za farumasi kugirango wirinde ubushuhe no gukumira imiti no kunoza ububiko buke bwibisate.
