    Iseluleko ngokuvikela umlilo nokuqhuma
    Izindlela ezijwayelekile zokuvikela umlilo.

    Iseluleko ngokuphathwa okuphephile
    Ungaphefumuli umusi/uthuli. Gwema ukuvezwa - thola imiyalelo ekhethekile ngaphambi kokusebenzisa. Gwema ukuthinta isikhumba namehlo. Ukubhema, ukudla nokuphuza kufanele kuvinjelwe endaweni esetshenziswayo. Lahla amanzi okuhlanza ngokuhambisana nemithetho yendawo neyezwe. Abantu abasengozini yezinkinga zokuzwela isikhumba noma i-asthma, ukungezwani komzimba, izifo zokuphefumula ezingamahlalakhona noma eziphindaphindayo akufanele basetshenziswe kunoma iyiphi inqubo lapho kusetshenziswa khona le ngxube.

    Izimo zokugcina okuphephile
    Gcina isitsha sivaliwe kahle endaweni eyomile futhi enomoya omuhle. Ukufakwa kukagesi/izinto zokusebenza kumele kuhambisane nezindinganiso zokuphepha zobuchwepheshe.

    Imibuzo Evame Ukubuzwa

    Ngikhiqiza izithiyo ze-polyurethane ezivikela umswakama ezinengxenye eyodwa. Isebenza kanjani i-DMDE?

    I-DMDE iyisikhuthazi esicashile; isebenza kuphela lapho kukhona umswakama, inikeze ukuqina kokugcinwa isikhathi eside (≥izinyanga ezingu-12).

    Izikhumba zami zokuvala zidlula ngokushesha kakhulu, zishiya imibimbi. Ngingazilungisa kanjani?

    Yehlisa i-DMDE ibe ngu-0.2–0.3 phr ukuze wehlise ijubane lokulungiswa kwendawo, uvumele isikhathi esanele sokulevelisha.

    Ingabe i-DMDE ingasetshenziswa kuma-adhesive e-polyurethane ancibilikisiwe (i-HMPUR)?

    Yebo, kuyindinganiso yemboni ye-HMPUR yokwelapha umswakama, enikeza ukujiya okuzinzile ku-120°C kanye namandla aluhlaza ngokushesha.

    Iyini isilinganiso esijwayelekile se-DMDE embozweni wephansi onengxenye eyodwa?

    0.5–1.0 phr (ngokusekelwe ku-prepolymer) isikhathi esingenazintambo samahora angu-2–4 ku-50% RH.

    I-elastomer yami eqeda umswakama inamabhamuza ngenxa yokukhishwa kwe-CO2 okusheshayo kakhulu. Ngingakulungisa kanjani?

    Yehlisa i-DMDE ibe ngu-0.1–0.2 phr bese ufaka umshini wokukhipha umswakama njenge-p-TSI.

    Ingabe i-DMDE ibangela ukuphuzi kwezimbozo ezinombala okhanyayo?

    Okuncane; kuyi-morpholine derivative futhi yaziwa ngokuqina kombala okuhle.

    Ingabe i-DMDE ingasetshenziswa kanye nezisefo ezomile ezifana nama-molecule?

    Yebo, kodwa qiniseka ukuthi izisefo azimunci i-DMDE; sebenzisa ifomu lokunamathisela noma uhlanganise ne-plasticizer kusengaphambili.

    I-foam sealant yami enengxenye eyodwa (i-can foam) ayinaso isikhathi sokuphelelwa yisikhathi. Ingabe i-DMDE ingayandisa?

    Yebo, amafomula asekelwe ku-DMDE angaba nesikhathi sokuphila sezinyanga ezingu-18-24 emathinini e-aerosol.

    Iyini inzuzo ye-DMDE kune-DBTDL ezinhlelweni zokwelapha umswakama?

    I-DMDE ayiyona into enobuthi (ayikho i-tin) futhi ayibangeli i-hydrolysis yamaqembu e-ester kuma-polyester polyols.

    Ngingayandisa kanjani ijubane lokuphulukiswa kwengubo enengxenye eyodwa ezimweni zasebusika ezibandayo nezomile?

    Khulisa i-DMDE ibe ngu-1.2–1.5 phr bese wengeza isisheshisi somswakama njengezinyibilikisi ezinikela ngamanzi.
