    Ukuphatha kunye nokugcina

    Amanyathelo okuzikhusela xa uphatha izinto ngokukhuselekileyo
    Gcina kude nemithombo yokutshaya - Akuvumelekanga ukutshaya. Thatha amanyathelo okhuseleko nxamnye nokuphuma kwamanzi angashukumiyo. Kuphephe ukudibana nolusu namehlo.
    Nxiba impahla yokuzikhusela epheleleyo ukuze uhlale ixesha elide kwaye/okanye ugxininiso oluphezulu. Nika umoya owaneleyo, kuquka indawo efanelekileyo.ukukhupha, ukuqinisekisa ukuba umda ochaziweyo wokuvezwa emsebenzini awudluli. Ukuba umoya awungeni ngokwaneleyo, ukhuseleko olufanelekileyo lokuphefumlakufuneka kubekho ucoceko lomntu. Kufuneka uhlambe izandla zakho kunye neendawo ezingcolisiweyo ngamanzi nesepha ngaphambi kokuba uphume emsebenzini.indawo.

    Imiqathango yokugcina ngokukhuselekileyo, kuquka naziphi na izinto ezingahambelaniyo
    Gcina kude nokutya, iziselo kunye nokutya kwezilwanyana. Gcina kude nemithombo yomlilo - Akuvumelekanga ukutshaya. Gcina kwindawo evaliweyo kakhuluisitya kwindawo eyomileyo, epholileyo nengena umoya kakuhle. Musa ukugcina kufutshane nemithombo yobushushu okanye uziveze kumaqondo obushushu aphezulu. Khusela ekuqandeni nasekukhanyeni kwelanga ngqo.

    FAQ

    Ndenza i-slabstock foam eguquguqukayo kwaye ndifuna ukunyuka ngokukhawuleza ngaphandle kokuqhekeka. Inganceda njani i-TMEDA?

    I-TMEDA sisincedisi sokuvuthela esisebenza ngokukhawuleza; sebenzisa i-0.05–0.15 phr kunye nesincedisi sejeli esilinganayo njenge-TEDA ukuze uphephe ukuqhekeka.

    Ngaba i-TMEDA inganciphisa ubungakanani bamanzi afunekayo ukuze kufikelelwe kuxinano lwefoam ekujoliswe kulo?

    Hayi ngokuthe ngqo, kodwa umsebenzi wayo onamandla wokutsala amandla ukuvumela ukuba ugcine i-reactivity nokuba kumanqanaba amanzi aphantsi (i-exotherm esezantsi).

    I-epoxy floor coating yam ithatha ixesha elide kakhulu ukuba inyangeke kwi-10°C. Ngaba i-TMEDA iya kuyikhawulezisa?

    Ewe, i-TMEDA sisikhawuleziso esisebenzayo kwiinkqubo ze-epoxy-amine, ingakumbi kumaqondo obushushu aphantsi.

    Yeyiphi indlela engcono yokuphepha ukutsha kwi-foam ye-TMEDA enamanzi amaninzi, ene-TMEDA ephezulu?

    Yehlisa i-TMEDA iye ngaphantsi kwe-0.1 phr kwaye wongeze i-antioxidant; cinga nangokutshintsha inxalenye ye-TMEDA nge-MOFAN A1.

    Ngaba i-TMEDA ibangela ukuqhakaza kwe-amine enamandla kumphezulu we-foam?

    Inokuguquguquka okuphezulu, ngoko ke ukudumba komphezulu kunokuvela. Sebenzisa amanqanaba aphantsi okanye emva kokunyanga kwi-50°C kangangeeyure ezi-2 ukuze uyisuse.

    Ndifuna i-catalyst yokwenza i-polyurethane adhesive ekhawuleza yokwenziwa ngomthi. Ngaba i-TMEDA lukhetho olufanelekileyo?

    Ewe, yongeza i-0.3–0.8% ngobunzima be-resin ukuze ufumane ixesha lokuvula elithatha imizuzu emi-5–10.

    Ngaba i-TMEDA ingasetyenziswa kwi-polyurethane elastomers kwiirola?

    Ewe, kodwa kuba itshintshatshintsha kakhulu, cinga ngokusebenzisa i-amine esebenzayo efana ne-MOFAN 50 kwizicelo zobushushu obuphezulu.

    I-insulation yam eqinileyo yokugalela i-foam iyakwazi ukugobeka kakhulu. Ngaba i-TMEDA ingandinceda?

    I-TMEDA ikakhulu ichaphazela ukuvuthela, hayi ukutrimerization; tshintshela kwi-catalyst ye-trimer efana ne-TMR-30 endaweni yoko.

    Ndingayigcina njani i-TMEDA ukuze iqhubeke isebenza ixesha elingaphezulu kweenyanga ezi-6?

    Gcina kwisitya esivalwe ngokuqinileyo, esigqunywe ngenitrogen kude nomswakama kunye nee-asidi; asibonakali kakuhle.

    Ngaba i-TMEDA ingatshintsha i-PMDETA (MOFAN 5) kwi-epoxy curing?

    Ngokuyinxenye; i-TMEDA ikhawuleza kodwa inika ubomi obufutshane bembiza. Sebenzisa i-TMEDA ukunyanga ubushushu obuphantsi, i-PMDETA ukunyanga ubushushu begumbi.
