    Amathegi Omkhiqizo

    Incazelo

    I-MOFAN K15 iyisisombululo se-potassium-salt ku-diethylene glycol. Ikhuthaza ukusabela kwe-isocyanurate futhi isetshenziswa ezinhlobonhlobo zezicelo ze-foam eqinile. Ukuze uthole ukwelashwa okungcono kwendawo, ukunamathela okuthuthukisiwe kanye nezinye izindlela zokugeleza okungcono, cabanga ngama-catalysts e-TMR-2

    Isicelo

    I-MOFAN K15 iyi-PIR laminate boardstock, iphaneli eqhubekayo ye-Polyurethane, i-spray foam njll.

    Ukuphatha nokugcina

    Iseluleko ngokuphathwa okuphephile
    Phatha ngokuhambisana nemithetho yezempilo kanye nokuphepha kwezimboni. Gwema ukuthintana nesikhumba namehlo. Nikeza ukushintshana komoya okwanele kanye/noma ukukhishwa komoya emakamelweni okusebenzela. Abesifazane abakhulelwe nabancelisayo kungenzeka bangadalulwa kumkhiqizo. Cabangela umthethonqubo kazwelonke.

    Izinyathelo Zokuhlanzeka
    Ukubhema, ukudla nokuphuza kufanele kuvinjelwe endaweni yokufaka isicelo. Geza izandla ngaphambi kwekhefu kanye nasekupheleni kosuku lomsebenzi.

    Izidingo zezindawo zokugcina kanye nezitsha
    Gcina kude nokushisa kanye nemithombo yokushisa. Vikela ekukhanyeni. Gcina isitsha sivaliwe kahle endaweni eyomile futhi enomoya omuhle.

    Iseluleko ngokuvikela umlilo nokuqhuma
    Gcina kude nemithombo yokushisa. Akuvunyelwe ukubhema.

    Iseluleko mayelana nokugcinwa okuvamile
    Akuhambisani nama-oxidizing agents.

    Imibuzo Evame Ukubuzwa

    Ngikhiqiza amaphaneli e-PIR aqinile adinga ukumelana nomlilo okukhulu. Isebenza kanjani i-K 15?

    I-K 15 iyisikhuthazi sokunciphisa uketshezi esisekelwe ku-potassium esikhuthaza ukwakheka kwendandatho ye-isocyanurate, okuthuthukisa kakhulu ukusebenza komlilo.

    Umugqa wami oqhubekayo wokulamina webhodi le-PIR uhamba kancane kakhulu. Ingabe i-K 15 ingandisa isivinini somugqa?

    Yebo, ku-0.5–1.5 phr kusheshisa i-trimerization, okuvumela isivinini esiphezulu semigqa (kufika ku-20% ngokushesha).

    Uyini umehluko phakathi kwe-K 15 ne-potassium acetate (K 2097)?

    I-K 15 (2-ethylhexanoate) incibilika kakhulu kuma-polyol futhi inikeza isikhathi eside sokhilimu, okungcono kakhulu kuma-mold ayinkimbinkimbi.

    I-foam yami eqinile ayinamatheli kahle ku-aluminium foil. Ngingayithuthukisa kanjani nge-K 15?

    Nciphisa i-K 15 ibe ngu-0.3–0.6 phr bese wengeza inani elincane le-catalyst yejeli (isb., i-MOFAN 8) ukuze ilinganisele.

    Ingabe i-K 15 ingasetshenziswa ku-spray PIR foam ukuze kuphahla?

    Yebo, inikeza ukuzinza okuhle kobukhulu kanye nokusebenza komlilo; sebenzisa i-phr engu-0.8–1.2.

    Iyini inkomba evamile ye-isocyanate (NCO/OH) uma usebenzisa i-K 15?

    250–400 ye-PIR foam; i-index ephezulu inikeza ukumelana okungcono komlilo kodwa i-fragile kakhulu.

    Ingabe i-K 15 ibangela ukugqwala kuma-facer ensimbi?

    Usawoti we-potassium uyagqwala kancane; gwema ukuthintana ngqo ne-aluminium; sebenzisa isithiyo uma kudingeka.

    Igwebu lami liyakwazi ukugoba kakhulu (ukuthulula uthuli). Ngingalinciphisa kanjani?

    Hlanganisa i-K 15 ne-catalyst ye-potassium acetate trimer (isb., MOFAN 2097) ngesilinganiso esingu-1:1 ukuze unciphise ukuqhekeka.

    Ingabe i-MOFAN K 15 ilingana ne-K 15?

    Yebo, ukushintshwa okuqondile; ukugxila kanye nomsebenzi ofanayo.

    Kufanele ngiyigcine kanjani i-K 15?

    Njengesixazululo ku-diethylene glycol; gcina esitsheni esivaliwe ngaphezu kuka-5°C ukuze ugweme ukukristala.
