    Amathegi Omkhiqizo

    Incazelo

    I-MOFAN DMAEE iyisikhuthazi se-amine esiphezulu sokukhiqizwa kwe-polyurethane foam. Ngenxa yomsebenzi wayo wokuvunguza kakhulu, ifaneleka kakhulu ukusetshenziswa ekwakhiweni okunokuqukethwe kwamanzi amaningi, njengokwakhiwa kwama-foam okupakisha aphansi. Iphunga le-amine elivame ukuvame ukuvame kuma-foam lincishiswa libe lincane ngokufakwa kwamakhemikhali kwento ku-polymer.

    Isicelo

    I-MOFAN DMAEE isetshenziselwa i-foam eguquguqukayo esekelwe ku-ester, ama-microcellular, ama-elastomers, i-RIM kanye ne-RRIM kanye nezinhlelo zokupakisha i-foam eqinile.

    Ukuphatha nokugcina

    Ukuphatha
    Izinyathelo zokuphepha zokuphatha ngokuphephile.
    Qinisekisa ukuthi ungena umoya kahle ezitolo nasezindaweni zokusebenza. Phatha ngokuhambisana nemikhuba emihle yokuhlanzeka kwezimboni kanye nokuphepha. Uma usebenzisa ungadli, ungaphuzi noma ubheme. Izandla kanye/noma ubuso kufanele bugezwe ngaphambi kwekhefu kanye nasekupheleni kweshifti.

    Ukuvikelwa emlilweni nasekuqhumeni
    Umkhiqizo uyasha. Vimbela ukushaja kwe-electrostatic - imithombo yokushisa kufanele igcinwe ihlanzekile - izicishi-mlilo kufanele zigcinwe ziseduze.

    Imibuzo Evame Ukubuzwa

    Ngikhiqiza i-foam yokupakisha ephansi futhi ngidinga i-catalyst engeke ibangele ukujiya ngokweqile. Yini esebenzayo?

    I-DMAAE ngokuyinhloko iyisikhuthazi esivunguzayo; yisebenzise ku-0.1–0.2 phr kanye nenani elincane lesikhuthazi sejeli njenge-TEDA.

    I-DMAAE inganciphisa kanjani ingozi yokuncipha kwegwebu ezingxenyeni ezibunjiwe?

    Isenzo sayo esinamandla sokuvunguza sivula amaseli, sinciphise okuqukethwe kwamaseli avaliwe okubangela ukuncishiswa kwesikhunta ngemuva kokubola.

    Igwebu lami eliqinile elipheshulwa ngamanzi linobuso obumahhadlahhadla. Ingabe i-DMAAE ingathuthukisa ukwakheka kweseli?

    Yebo, kukhuthaza amangqamuzana acwebezelayo ngokulibazisa ukwakheka kwejeli kuze kube yilapho i-bubble nucleation isiqediwe.

    Iyini inzuzo ye-DMAAE kune-BDMAEE (A-99) ezinhlelweni zamanzi aphezulu?

    I-DMAAE ayiguquguquki kakhulu futhi iphakamisa kancane kancane, okwenza kube lula ukuyicubungula ekubunjweni kwesikhunta esivulekile.

    Ingabe i-DMAAE ingasetshenziswa kuma-sealant okwelapha umswakama anengxenye eyodwa?

    Akukhuthazwa; akubangelwa umswakama. Sebenzisa i-DMDEE (MOFAN DMDE) esikhundleni salokho.

    Isembozo sami se-PU sinama-crane ngenxa yokuhwamuka okusheshayo kwe-catalyst. Ungakugwema kanjani?

    Shintshela ku-DMAAE, enezinga lokubila eliphezulu futhi ehlala isikhathi eside efilimini.

    Ingabe i-DMAAE ibangela ukuphuzi kwama-elastomer asekelwe ku-isocyanate aromatic?

    Okuncane; kuyi-amine ye-aliphatic, eshintsha umbala kancane kune-aromatic amines.

    Ngidinga ukwenza ijeli ye-polyurethane ecacile ukuze ngiyisebenzisele ukukhanya. Ingabe i-DMAAE iyamukeleka?

    Yebo, umbala wayo ophansi osele kanye nokuhambisana okuhle kwenza ifanelekele ama-gel acacile ngamanani aphansi (<0.3 phr).

    Ngingayandisa kanjani isikhathi sokuvula kwesinamathelisi se-polyurethane esinezingxenye ezimbili ngaphandle kokudela amandla okugcina?

    Faka i-DMAAE esikhundleni sengxenye ye-gel catalyst; yelula isikhathi sokhilimu ngenkathi isavumela ukuphulukiswa okuphelele.

    Ingabe i-DMAAE ingasetshenziswa ku-polyurethane foam kumadivayisi okuntanta?

    Yebo, ukusabela kwayo okulinganiselayo kusiza ekukhiqizeni igwebu elifana neleseli elivaliwe elinokuthamba okuhle.
