Sebenzisa:I-methyl tetrahydrophthalic anhydride ingahle isetshenziselwe i-poryester resin engafakwanga, i-epen relin ephula umthetho, i-pesticide Intermediate, poting for transformer, njll.
Isingeniso Esinemininingwane
I-methyl tetrahydrophthalic anhydride (MthPA)iyingxenye yamakhemikhali engokwesigaba se-cyclic anhydrides. Kuyindawo ehlanganisiwe ngefomula ye-molecular c9h10o3.
UMthpa uvame ukusetshenziswa njenge-ejenti elapha noma eqinile kuma-epoxy resins. Kuyindawo ehlukahlukene enikezela ngezinzuzo ezahlukahlukene ekwenziweni nasekukhiqizweni kwezinto ezisekelwa nge-epoxy. I-MTHPA yaziwa ngokumelana kwayo okuhlukile kokushisa, ukumelana kwamakhemikhali, nezindawo ezinhle kakhulu ezinamathela.
Enye yezinhlelo zokusebenza eziphambili zeMthPA isemboni kagesi nezogesi. Kusetshenziswa kabanzi ekukhiqizweni kwezinto zokwakha ugesi ezifana nezimbambo, ama-varnish, amakhompiyutha aphonsa, nama-laminates. UMthpa usiza ukuthuthukisa izakhiwo zokufakwa kukagesi zalezi zinto zokwakha, ukuzenza zilungele izinhlelo zokusebenza ku-transformers, motor, amabhodi wesifunda, nezinye izingxenye ze-elekthronikhi.
Enye indawo ebalulekile lapho uMthpa ethola khona uhlelo lokusebenza ekwenziweni kwama-composites. Isetshenziswa njenge-ejenti elapha ama-composites asuselwa ku-epoxy afana ne-fiberglass, ama-polymers aqinisiwe we-carbon fiber aqinisiwe (CFRP), nezinye izinto ezi-composite eziphezulu. UMthpa ufaka isandla kumandla okwenziwa ngomshini, ukuqina kanye nokumelana nezici zalezi zinhlanganisela.
I-MTHPA nayo isetshenziswa kwezinye izimboni ezahlukahlukene kanye nezicelo kufaka phakathi anamathela, ukugqoka, ubunjiniyela bomphakathi, ukusakaza nokubumba. Inikeza ukunamathela okuhle kakhulu, ukumelana kwamakhemikhali, kanye nezakhiwo zokuzinquma okushisayo, okwenza kube yigugu kulezi zicelo.
Kodwa-ke, kubalulekile ukuphatha uMthpa ngokunakekelwa njengoba kungaba yingozi futhi kuyacasula esikhunjeni, emehlweni nasezinhlelweni zokuphefumula. Ukuphepha okufanelekile kokuphepha, njengokugqoka imishini yokuvikela nokusebenza endaweni enomoya omuhle, kufanele kulandelwe lapho kuphathwa futhi kusetshenziswa uMthpa.
Isicelo
I-Methyl TetrahydrophHhalic Anhydride (MthPA) iyingxenye ye-cyclic anhydride evame ukusetshenziswa njenge-ejenti yokulapha noma i-hardener kuma-epoxy resins. Kuyinto uketshezi oluphansi oluphansi emazingeni okushisa asekamelweni futhi kwaziwa ngezakhiwo zalo ezinhle kakhulu zamakhemikhali kanye nokushisa.
I-MTHPA isetshenziswa kabanzi emikhakheni ehlukahlukene efana nokufakwa kukagesi, ama-composites, ukumboza, ukunamathela, nokuphonsa. Ibaluleke kakhulu njenge-ejenti yokupheqa ngezicelo ezidinga ukunamathela okuqinile, amandla aphezulu emishini, kanye nokumelana namakhemikhali nokushisa.
Ukusetshenziswa okuthile kwe-MTHPA kufaka phakathi:
Ama-adhesives asuselwa e-epoxy:I-MTHPA ingasetshenziswa njenge-hardener ekunamathisweni kwezicelo ze-bonding ezidinga amandla aphezulu nokuqina.
Ukufakwa kukagesi:UMthpa uvame ukusetshenziswa ekwenziweni kwezinto zokwakha ugesi ezifana nama-laminate, amakhompiyutha aphonsa, kanye nama-resin ahlanganisiwe.
Ama-Composites: I-MTHPA isetshenziswa njenge-ejenti elapha ekwenziweni kwezinto ezihlanganisiwe, kufaka phakathi i-plastics eqinisiwe ye-fiber (php), imikhiqizo ye-carbon fiber, nemikhiqizo ecubuziwe.
I-Coatings:I-MthPA ingasetshenziswa njengesengezo ekugqokeni ukuthuthukisa ukumelana kwamakhemikhali, ukunamathela, kanye nobunzima.
Ukuphonsa nokubumba:I-MTHPA isetshenziswa ekukhiqizweni kwama-resin aphonsa kanye nokubumba, ukuhlinzeka ngokuqina kobukhulu kanye nokumelana nokushisa namakhemikhali.
Kuyafaneleka ukusho ukuthi uMthpa angaba nobuthi futhi acasule isikhumba, ngamehlo, kanye nohlelo lokuphefumula. Ukuphepha okufanelekile kokuphepha, okubandakanya ukusetshenziswa kwemishini yokuvikela nokusebenza ezindaweni ezinomoya owanele, kufanele kulandelwe njalo lapho uphatha le nhlanganisela.
