4. The insulating varnish

A irin zafi rufi Paint da Paint samar, trimellitic anhydride amfani a yi na polyester imide Paint, modified polyester da polyamide imide lacquer Paint, da samfurin yana da kyau zafi juriya, na iya zama a cikin dogon lokacin da amfani da 200 ℃ da kuma sama), sa juriya, juriya ga lalacewa, lantarki rufi (karshe irin ƙarfin lantarki iya isa 11.5 inji Properties, da kuma inji Properties). a yi amfani da shi azaman resin laminate don zanen gilashin da ba a ciki, kayan abin rufewa mai zafi mai zafi, fenti don waya da insulator don mota da sauran kayan aikin lantarki.

5. Surfactant

Za a iya shirya surfactant tare da kyakkyawan aiki mai kyau ta hanyar mono-biyu esterification na trimellitic anhydride da m alcohols kamar lauryl barasa da octadecyl barasa, sa'an nan kuma free carboxyl kungiyar a kan trimellitic anhydride an neutralized ta NaOH.

6. Sauran amfani

Phenylimide resin da aka yi daga trimalic anhydride za a iya mai da shi a 250 ~ 300 ℃ na dogon lokaci. Ana iya amfani da shi don kera sassan filastik da aka ƙera kamar kayan aikin lantarki, bawul, bearings da sassan injin jet. Bugu da kari, trimellitic anhydride ana amfani dashi sosai a cikin kayan shafawa na jirgin sama, rini, tawada, magunguna da sinadarai na aikin gona. Ana amfani da samfuran da aka yi da anhydride a cikin wayoyi da igiyoyi na lantarki, kayan ado na ciki na mota, fata na wucin gadi, injin magudanar ruwa, makafi, jakunkuna, kayan rufewa da filaye, da sauransu.

Guba na trimellitic anhydride

Trimellitic anhydride mai guba ne kuma yana iya fusatar da huhu, ido, mucosa na hanci da fata, yana haifar da rashin lafiyan halayen da sauran cututtuka. Matsakaicin abin da aka yarda da shi a cikin iska shine 1mg/m3. Wurin aiki ya kamata ya kasance da iska mai kyau, kuma masu aiki su sanya abin rufe fuska, gilashin kariya da kayan kariya masu dacewa.

Lokacin haɗari	R37	Yana ƙarfafa tsarin numfashi.
