Iyini i-Trimellitic Anhydride? Yiziphi Ukusetshenziswa kwe-Trimellitic Anhydride?

Iyini i-trimellitic anhydride?

I-Trimellitic anhydride , 1,2,4-Benzenetricarboxylic anhydride. Ifomula yamangqamuzana ithi C9H4O5. Ukubonakala kuyi-flake emhlophe noma impushana. Indawo encibilikayo ye-trimellitic anhydride ingu-168℃ kanti indawo yokubilisa ingu-390℃. I-Trimaric anhydride incibilike emanzini ashisayo ne-acetone, i-2-J ketone, i-dimethylformamide, i-ethyl acetate, i-cyclohexanone. Iyancibilika ku-ethanol anhydrous futhi iyasabela, futhi inyibilika kancane ku-carbon tetrachloride ne-toluene. I-Trimellitic anhydride isetshenziswa ngokuyinhloko njenge-ejenti yokwelapha ye-epoxy resin, futhi ingasetshenziswa ekukhiqizeni i-plasticizer, i-coating, insulating paint, i-surfactant nokunye.

Ukusetshenziswa kwe-trimellitic anhydride

1. Ipulasitiki

I-Triisooctyl trimelate (TOTM) ikhiqizwa ukusabela kwe-esterification ye-trimelate anhydride ne-2-ethylhexanol. I-TOTM plasticizer inezinzuzo ze-fluidity enhle, ukumelana nokushisa (iphuzu eliphakeme le-flash), ukuguquguquka okuphansi, izakhiwo zikagesi eziphakeme, ukumelana nazo zonke izinhlobo zokukhishwa kwe-solvent, nokumelana okuncane nokufuduka. Ingakwazi ukuhlangabezana nezidingo ze-90 ℃, 105 ℃, 125 ℃ grade grade resistant cable kanye high voltage cable emgodleni plastic.

2. Ukugqoka

Ingxube entsha ye-alkyd resin encibilikayo emanzini ingatholwa ngokusabela kwe-trimellitic anhydride nge-dialcohol monoglyceride, i-hexanediol, i-propylene glycol, i-neopenyl glycol namanye ama-dialcohols, angasetshenziswa njenge-electrophoretic primer yezimoto, iziqandisi nemishini yokuwasha.

3. I-epoxy yokwelapha i-ejenti

Uma isetshenziswa njenge-ejenti elaphayo ye-epoxy resin, i-trimellitic anhydride inokuphinda isebenze futhi ingalapha i-epoxy resin ngesikhathi esifushane. Umkhiqizo oqinisiwe unokushisa okuphezulu kokushisa okushisayo, izakhiwo ezinhle kakhulu zemishini, izakhiwo zikagesi kanye nokumelana nezidakamizwa, ezifanele i-epoxy castings kanye nemikhiqizo ye-laminate. I-resin eqinile etholwe ukusabela kwe-trimellitic anhydride ne-glycerol, encibilikisiwe ku-solvent, inokunamathela okuhle engilazini, i-aluminium, njll.

4. I-varnish evikelayo

Ohlotsheni lokufakwa kokushisa upende nokukhiqizwa kopende, i-trimellitic anhydride esetshenziswa ekwenzeni upende we-polyester imide, i-polyester eguquliwe kanye ne-polyamide imide lacquer ngopende, umkhiqizo unokumelana okuhle nokushisa, ungaba ekusetshenzisweni kwesikhathi eside kwe-200 ℃ nangaphezulu), ukumelana nokugqoka, ukumelana nokulimala, ukwahlukanisa ugesi (i-voltage yokuwohloka ingafinyelela ku-11.5 kV, iklasi le-H lingasetshenziswa njenge-varnish). I-laminate resin yendwangu yengilazi egxilile, izinto zokumboza ezimelana nokushisa okuphezulu, upende ovikelayo wocingo kanye nesivikeli se-slot semoto nezinye izinto zikagesi.

5. I-surfactant

I-surfactant esebenza kahle kakhulu engaphezulu ingalungiswa nge-mono-double esterification ye-trimellitic anhydride kanye notshwala obunamafutha njenge-lauryl alcohol ne-octadecyl alcohol, bese iqembu lamahhala le-carboxyl ku-trimellitic anhydride lincishiswa yi-NaOH.

6. Okunye ukusetshenziswa

I-Phenylimide resin eyenziwe nge-trimalic anhydride ingashiswa ku-250 ~ 300 ℃ isikhathi eside. Ingasetshenziselwa ukwakha izingxenye zepulasitiki ezibunjiwe ezifana nezingxenye zikagesi, ama-valve, ama-bearings kanye nezingxenye zenjini ye-jet. Ngaphezu kwalokho, i-trimellitic anhydride isetshenziswa kakhulu kumafutha ezindiza, odayi, oyinki, emithini yemithi kanye namakhemikhali ezolimo. Imikhiqizo eyenziwe nge-anhydride isetshenziselwa izintambo zikagesi nezintambo, umhlobiso wangaphakathi wemoto, isikhumba sokwenziwa, ipayipi lokudonsa umshini wokuwasha, izimpumputhe, izikhwama, izinto zokuvala kanye nezigcwalisi, njll.

Ubuthi be-trimellitic anhydride

I-Trimellitic anhydride inobuthi futhi ingacasula amaphaphu, iso, i-mucosa yamakhala kanye nesikhumba, ibangele ukungezwani komzimba nokunye ukuphazamiseka. Isilinganiso esiphezulu esivumelekile emoyeni singu-1mg/m3. Indawo okusetshenzwa kuyo kufanele ibe nomoya omuhle, futhi opharetha kufanele bagqoke imaski yokuzivikela, izibuko zokuzivikela kanye nezinto zokuzivikela ezifanele.

Isikhathi sobungozi	R37	Ivuselela uhlelo lokuphefumula.
	R41	Umonakalo omkhulu wamehlo.
	R42/43	Ingezwa ngokuhogela kanye nokuthinta isikhumba.
Isikhathi sokuphepha	S22	Ungahogeleli uthuli.
	S26	Uma uthintana namehlo, hlambulula ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.
	S36/37/39	Gqoka izingubo zokuzivikela ezifanele, amagilavu ​​kanye nezibuko noma imaski.

Ukupakishwa nokugcinwa kwe-trimellitic anhydride

I-Trimellitic anhydride ivamise ukupakishwa ezikhwameni zepulasitiki ezilayini ezingu-25kg, zigcinwe endaweni epholile, engenisa umoya futhi eyomile, ukushisa, umswakama, isivikelo elangeni, kude nokushisa.
