Isicelo Somkhiqizo

I-MTHPA isetshenziswa kakhulu njenge-ejenti yokwelapha ama-resin e-epoxy. Inomkhuba omncane wokumunca umswakama emoyeni kanye nokwakheka kwe-carbon dioxide okungu-zero noma okuncane uma ixutshwe nama-accelerator e-tertiary amine.

I-MTHPA ingaxutshwa kalula nama-resin ahlukahlukene oketshezi anikeza ingxube eqinile, ethambile futhi ehlala isikhathi eside ebhodweni.

Isetshenziswa kabanzi ku:

− Ukuphonsa/Ukufaka Ebhodweni

− Ukuminza

− Ukubopha

Emkhakheni wepulasitiki eqinisiwe isetshenziselwa imikhiqizo yamanxeba e-filament (amapayipi kawoyela, izigxobo kanye nezimpahla zezemidlalo), amashidi alaminethiwe, amabhodi wesekethe aphrintiwe, amagiya okushintsha.

Ngenxa yezakhiwo zayo ezinhle kakhulu zokuvikela ukushisa, i-MTHPA ithole izinhlelo eziningi zokukhiqiza izingxenye zikagesi ezifana nalezi: ama-capacitor, ama-resistor, izingxenye zokuxhuma ama-transformer, ama-ignition coil, nama-fly back transformers.

I-Methyltetrahydrophthalic anhydride (i-MTHPA) iyinhlanganisela yamakhemikhali ewela ngaphansi kwesigaba sama-anhydride ajikelezayo. Isetshenziswa kakhulu njenge-ejenti yokwelapha kuma-resin epoxy. Nazi ezinye zezinzuzo eziyinhloko ze-MTHPA:
1. Izakhiwo zokupholisa: I-MTHPA iyi-ejenti yokupholisa ephumelelayo yama-epoxy resins, enikeza ukumelana okuhle kakhulu nokushisa namakhemikhali. Isiza ukuguqula i-epoxy resin ewuketshezi ibe yinto eqinile, eqinile, ne-thermoset, okwenza ifaneleke ukusetshenziswa okuhlukahlukene.
2. I-viscosity ephansi: I-MTHPA ngokuvamile ine-viscosity ephansi uma iqhathaniswa nezinye izinto zokupholisa, okwenza kube lula ukuphatha nokuxuba nama-epoxy resins, okuthuthukisa izici zokucubungula kanye nokusetshenziswa.
3. Ukuqina okuhle kokushisa: I-epoxy elungisiwe ene-MTHPA ibonisa ukuqina okuhle kokushisa, okwenza ifaneleke ukusetshenziswa lapho ukumelana nokushisa kubalulekile khona.
4..Izakhiwo zikagesi ezinhle: Ama-resin epoxy alungisiwe ane-MTHPA njenge-ejenti yokwelapha avame ukuba nogesi ofiselekayo.

Ukupakisha

Ukupakisha: isigubhu esine-galvanized esingama-220 kg ngobuningi uma ucela olunye uhlobo lokupakisha lungatholakala.

Indawo yokugcina: kumele igcinwe kude namalangabi avulekile noma eminye imithombo yokushisa engaba khona, futhi kufanele ivikelwe emswakama ngoba, ikakhulukazi i-PI kanye nezinguqulo ezingu-600, iqina kalula uma ithintana nomswakama womoya. Ebusika i-MTHPA ingaqina, ingancibilikiswa kalula ngokufudumeza nje.

Impilo yeshelufu: Izinyanga eziyi-12 kusukela osukwini lokukhiqiza.

Ukugcinwa Nokuthuthwa Komkhiqizo

Ngaphandle kokuthi kuchazwe ngenye indlela, imikhiqizo ye-MTHPA kufanele igcinwe endaweni eyomile, epholile futhi engangeni umswakama. Kungcono ukuyisebenzisa zingakapheli izinyanga eziyi-12 kusukela ngosuku lokukhiqiza. Kufanele ihlale emaphaketheni ayo okuqala kuze kube yilapho isetshenziswa. Imikhiqizo ifanele ukulethwa ngomkhumbi, isitimela, noma iloli.
