    Incazelo

    I-MOFAN DPA iyisikhuthazi se-polyurethane esivunguzayo esisekelwe ku-N,N,N'-trimethylaminoethylethanolamine. I-MOFAN DPA ifanele ukusetshenziswa ekukhiqizeni i-polyurethane foam eguquguqukayo, eqinile kancane, neqinile. Ngaphezu kokukhuthaza ukusabela okuvunguzayo, i-MOFAN DPA iphinde ikhuthaze ukusabela okuxhumene phakathi kwamaqembu e-isocyanate.

    Isicelo

    I-MOFAN DPA isetshenziswa ku-foam eguquguqukayo, eqinile kancane, i-foam eqinile njll.

    Imibuzo Evame Ukubuzwa

    Ngikhiqiza izembozo ze-polyurethane ezitholakala emanzini ezingenaphunga eliningi. Ingasiza kanjani i-DPA?

    I-DPA iyi-amine enephunga eliphansi, esabelayo enciphisa iphunga le-amine ngesikhathi sokusetshenziswa nangemva kokwakheka kwefilimu.

    I-polyurethane elastomer yami ayinawo amandla okudabuka amahle. Ingabe i-DPA ingayithuthukisa?

    Yebo, isakhiwo sayo se-diisopropanolamine singandisa ukuminyana kwe-crosslink kanye nokumelana nokudabuka uma sisetshenziswa ku-0.2–0.5 phr.

    Iyini isilinganiso esijwayelekile se-DPA ku-polyurethane sealant ukuze kuthuthukiswe ukunamathela kukhonkolo?

    0.3–0.6 phr; kuthuthukisa ukumanzisa kanye nokubopha kwamakhemikhali ezindaweni zamaminerali.

    Ingabe i-DPA ingasetshenziswa njenge-co-catalyst kuma-polyurethane spray foams ukunciphisa iphunga?

    Yebo, kuyasiza ukwehlisa ukuguquguquka kwama-amine; kuvame ukuhlanganiswa ne-MOFAN 33LV.

    Isinamathelisi sami se-polyurethane se-PVC asimelani kahle nokushisa. Ngingasithuthukisa kanjani?

    Engeza i-DPA (0.4 phr) ukuze wandise ubuningi bokuxhumanisa, ukhuphule izinga lokushisa lokushintsha kokushisa.

    Ingabe i-DPA iyahambisana nezinhlelo zokwelapha umswakama?

    Ingasetshenziswa, kodwa ngoba iqukethe amaqembu e-OH, izosabela nge-isocyanate. Sebenzisa ezinhlelweni ezinezingxenye ezimbili kuphela.

    I-DPA iqhathaniswa kanjani ne-triethanolamine (TEOA) njenge-crosslinker?

    I-DPA iyisikhuthazi esingcono futhi iyisixhumi esithambile; i-TEOA ngokuyinhloko iyisixhumi esinomsebenzi obuthakathaka wokuvuselela.

    I-polyurethane foam yami yokupakisha ilulama kancane ngemva kokucindezelwa. Ingabe i-DPA ingakulungisa lokhu?

    Yebo, khulisa i-DPA ibe ngu-0.2–0.3 phr ukuze uthuthukise ukwakheka kwenethiwekhi enwebekayo.

    Ingabe i-DPA ingasetshenziswa ezinhlelweni ze-epoxy ukuthuthukisa ukuguquguquka?

    Yebo, njengomuguquli kunganciphisa ukuphuka ngaphandle kokunciphisa ukuphulukiswa.

    Iyini impilo yeshelufu yengxube ye-polyol equkethe i-DPA?

    Okungenani izinyanga eziyisithupha uma igcinwe esitsheni esomile nesivaliwe.
