    Su'aalaha Badiya La Weydiiyo

    Waxaan soo saaraa shaabad-xidhayaal polyurethane ah oo hal qayb ka ah qoyaan-daaweynta. Sidee bay DMDE u shaqeysaa?

    DMDE waa kiciye qarsoon; waxay noqotaa mid firfircoon oo keliya marka qoyaanku jiro, taasoo siinaysa xasillooni kaydin oo dheer (≥12 bilood).

    Maqaarkayga shaabadaysan ayaa si dhakhso ah u soo baxaya, taasoo ka tagaysa laalaab. Sidee loo hagaajiyaa?

    Hoos u dhig DMDE ilaa 0.2–0.3 phr si aad u yareyso bogsashada dusha sare, taasoo kuu ogolaaneysa waqti ku filan oo lagu simo.

    Ma loo isticmaali karaa DMDE dhejisyada polyurethane ee dhalaala kulul (HMPUR)?

    Haa, waa heerka warshadaha ee HMPUR-daaweynta qoyaanka, taasoo bixinaysa isku-dhafnaan deggan oo ah 120°C iyo xoog cagaaran oo degdeg ah.

    Waa maxay qiyaasta caadiga ah ee DMDE ee dahaarka dabaqa hal-qaybood leh?

    0.5–1.0 phr (oo ku salaysan prepolymer) muddo aan lahayn tackle oo ah 2–4 saacadood oo ah 50% RH.

    Elastomer-kaygu wuxuu leeyahay xumbo sababtoo ah sii deynta CO2 oo aad u dhakhso badan. Sidee loo hagaajiyaa?

    Yaree DMDE ilaa 0.1–0.2 phr oo ku dar qalab qoyaan-qoyan sida p-TSI.

    DMDE ma keentaa huruud ku dhaca shaabadaha midabka khafiifka ah leh?

    Ugu yar; waa nooc ka soo jeeda morpholine waxaana loo yaqaanaa xasilloonida midabka wanaagsan.

    Ma loo isticmaali karaa DMDE iyadoo lala isticmaalayo shaandho qalajiye sida molecular-ka?

    Haa, laakiin hubi in shaandhada aysan nuugin DMDE; isticmaal qaab koollo ah ama horay ugu qas balaastigeeye.

    Shaabadeeyahayga hal-qaybood leh (xumbada karinta) wuxuu leeyahay cimri kaydin oo liita. DMDE ma dheereyn kartaa?

    Haa, qaacidooyinka ku salaysan DMDE waxay yeelan karaan cimri kayd ah oo ah 18-24 bilood oo ku jira qasacadaha aerosol-ka.

    Waa maxay faa'iidada DMDE marka loo eego DBTDL ee nidaamyada daaweynta qoyaanka?

    DMDE ma aha sun (ma laha daasad) mana keento hydrolysis kooxaha ester-ka ee ku jira polyester polyols.

    Sideen u kordhin karaa xawaaraha bogsashada ee dahaarka hal-qaybood leh xaaladaha jiilaalka qabow iyo qalalan?

    Kordhi DMDE ilaa 1.2–1.5 hr oo ku dar dardar-geliye qoyaan sida dareere biyo bixiya.
