    FAQ

    Ndimapanga zinthu zomatira za polyurethane zomwe zimachotsa chinyezi m'thupi. Kodi DMDE imagwira ntchito bwanji?

    DMDE ndi chothandizira chobisika; chimagwira ntchito pokhapokha ngati pali chinyezi, zomwe zimapangitsa kuti chisungidwe bwino kwa nthawi yayitali (≥miyezi 12).

    Khungu langa lotsekeka limatuluka mofulumira kwambiri, zomwe zimasiya makwinya. Kodi ndingasinthe bwanji?

    Chepetsani DMDE kufika pa 0.2–0.3 phr kuti muchepetse kuchira kwa pamwamba, zomwe zimakupatsani nthawi yokwanira yoti muyezetse.

    Kodi DMDE ingagwiritsidwe ntchito mu zomatira za polyurethane zosungunuka ndi madzi (HMPUR)?

    Inde, ndiye muyezo wamakampani wa HMPUR wochiritsa chinyezi, womwe umapereka kukhuthala kokhazikika pa 120°C komanso mphamvu yobiriwira mwachangu.

    Kodi mlingo wa DMDE wokhazikika pa utoto wa pansi wa gawo limodzi ndi wotani?

    0.5–1.0 phr (kutengera prepolymer) kwa nthawi yopanda kugwedezeka kwa maola 2–4 ​​pa 50% RH.

    Elastomer yanga yochiritsa chinyezi ili ndi thovu chifukwa cha kutulutsa CO2 mwachangu kwambiri. Kodi ndingakonze bwanji?

    Chepetsani DMDE kufika pa 0.1–0.2 phr ndikuwonjezera chotsukira chinyezi monga p-TSI.

    Kodi DMDE imayambitsa chikasu m'ma sealant opepuka?

    Chochepa; ndi chochokera ku morpholine ndipo chimadziwika ndi kukhazikika kwa mtundu.

    Kodi DMDE ingagwiritsidwe ntchito pamodzi ndi ma sieve ouma ngati ma molecular?

    Inde, koma onetsetsani kuti ma sefa sakuyamwa DMDE; gwiritsani ntchito mawonekedwe a phala kapena sakanizani ndi pulasitiki.

    Chotsekera changa cha thovu chokhala ndi gawo limodzi (thovu la chitini) sichikhala ndi nthawi yokwanira yosungira. Kodi DMDE ingachiwonjezere?

    Inde, mankhwala opangidwa ndi DMDE amatha kukhala ndi moyo wa miyezi 18-24 m'mabotolo a aerosol.

    Kodi ubwino wa DMDE kuposa DBTDL ndi wotani m'makina ochiritsira chinyezi?

    DMDE si poizoni (yopanda tin) ndipo siyimayambitsa hydrolysis ya magulu a ester mu polyester polyols.

    Kodi ndingawonjezere bwanji liwiro la kuchira kwa chophimba cha gawo limodzi m'nyengo yozizira komanso youma?

    Wonjezerani DMDE kufika pa 1.2–1.5 phr ndikuwonjezera cholimbikitsira chinyezi monga zosungunulira zomwe zimapereka madzi.
