    Ukuphatha kunye nokugcina

    Iingcebiso malunga nokukhusela umlilo kunye nokuqhuma
    Amanyathelo aqhelekileyo okukhusela umlilo.

    Iingcebiso malunga nokuphathwa ngokukhuselekileyo
    Musa ukuphefumla umphunga/uthuli. Kuphephe ukuvezwa - fumana imiyalelo ekhethekileyo ngaphambi kokusebenzisa. Kuphephe ukudibana nolusu namehlo. Ukutshaya, ukutya nokusela kufuneka kungavumelekanga kwindawo esetyenziswa kuyo. Lahla amanzi okuhlamba ngokuhambelana nemigaqo yengingqi neyelizwe. Abantu abasengozini yokuba neengxaki zolusu okanye i-asthma, i-allergies, izifo zokuphefumla ezingapheliyo okanye eziphindaphindayo akufuneki basetyenziswe kuyo nayiphi na inkqubo apho lo mxube usetyenziswa khona.

    Iimeko zokugcina ngokukhuselekileyo
    Gcina isikhongozeli sivaliwe kakuhle kwindawo eyomileyo nengena umoya. Ukufakelwa kombane/izixhobo zokusebenza kufuneka zihambelane nemigangatho yokhuseleko yetekhnoloji.

    Izixhobo ekufuneka ziphetshwe
    Gcina kude nee-asidi ezinamandla.

    FAQ

    Ndivelisa izitywini ze-polyurethane ezikhusela umswakama ezinecandelo elinye. Isebenza njani i-DMDE?

    I-DMDE sisithinteli esifihlakeleyo; isebenza kuphela xa kukho umswakama, nto leyo enika uzinzo oluhlala ixesha elide (≥iinyanga ezili-12).

    Ulusu lwam oluvala isivalo lukhawuleza kakhulu, lushiya imibimbi. Ndingalulungisa njani?

    Yehlisa i-DMDE ukuya kwi-0.2–0.3 phr ukuze unciphise ukuchacha komphezulu, uvumele ixesha elaneleyo lokulinganisa.

    Ngaba i-DMDE ingasetyenziswa kwiiglu ze-polyurethane ezinyibilikisiweyo (i-HMPUR)?

    Ewe, ngumgangatho weshishini we-HMPUR onyanga ukufuma, obonelela nge-viscosity ezinzileyo kwi-120°C kunye nokuqina okuluhlaza ngokukhawuleza.

    Ithini idosi eqhelekileyo ye-DMDE kwi-floor coating enecandelo elinye?

    0.5–1.0 phr (isekelwe kwi-prepolymer) ixesha elingena-tack leeyure ezi-2–4 kwi-50% RH.

    I-elastomer yam enyanga ukufuma inamaqamza ngenxa yokukhutshwa kwe-CO2 ngokukhawuleza kakhulu. Ndingalungisa njani?

    Yehlisa i-DMDE ibe yi-0.1–0.2 phr uze wongeze isixhobo sokucoca umswakama esifana ne-p-TSI.

    Ngaba i-DMDE ibangela ukutyheli kwii-sealants ezinombala okhanyayo?

    Incinci; yi-morphine derivative kwaye yaziwa ngokuqina kombala kakuhle.

    Ngaba i-DMDE ingasetyenziswa kunye nezihluzo ezomileyo ezifana neemolekyuli?

    Ewe, kodwa qiniseka ukuba izihluzo azifunxi i-DMDE; sebenzisa uhlobo lwentlama okanye udibanise ne-plasticizer kwangaphambili.

    I-foam sealant yam enenxalenye enye (i-can foam) ayinaxesha lide lokugcinwa. Ngaba i-DMDE ingayandisa?

    Ewe, iifomyula ezisekelwe kwi-DMDE zinokuphila ixesha eliphakathi kweenyanga ezili-18-24 kwiinkonkxa ze-aerosol.

    Yintoni inzuzo ye-DMDE kune-DBTDL kwiinkqubo zokucoca umswakama?

    I-DMDE ayinabungozi (ayina tin) kwaye ayibangeli i-hydrolysis yamaqela eester kwi-polyester polyols.

    Ndingayonyusa njani isantya sokuphiliswa kwengubo enenxalenye enye kwiimeko ezibandayo nezomileyo zasebusika?

    Yongeza i-DMDE ukuya kwi-1.2–1.5 phr kwaye wongeze isixhobo sokukhawulezisa ukufuma njengesinyibilikisi esinikela ngamanzi.
