    Incazelo

    I-TEDA Crystalline catalyst isetshenziswa kuzo zonke izinhlobo zama-polyurethane foams kufaka phakathi i-flexible slabstock, flexible molded, rigid, semi-flexible kanye ne-elastomeric. Iphinde isetshenziswe ekusetshenzisweni kwe-polyurethane coatings. I-TEDA Crystalline catalyst isheshisa ukusabela phakathi kwe-isocyanate namanzi, kanye naphakathi kwamaqembu e-isocyanate kanye ne-organic hydroxyl.

    Isicelo

    I-MOFAN TEDA isetshenziswa ezitsheni eziguquguqukayo, ezibunjiwe ngendlela eguquguqukayo, eqinile, eguquguqukayo kancane kanye ne-elastomeric. Iphinde isetshenziswe ezimbozweni ze-polyurethane.

    Ukuphatha nokugcina

    Izinyathelo Zokuqapha Ukuphatha Ngokuphephile Gwema ukuthintana namehlo. Sebenzisa imishini yokuzivikela. Uma usebenzisa, ungadli, ungaphuzi noma ungabhemi. Izimo zokugcina okuphephile, okuhlanganisa noma yikuphi ukungahambisani. Ungagcini eduze kwama-asidi. Gcina ezitsheni zensimbi okungcono zibe ngaphandle, ngaphezu komhlaba, futhi uzungezwe yimisele ukuze uvimbele ukuchitheka noma ukuvuza. Gcina izitsha zivaliwe kahle endaweni eyomile, epholile futhi enomoya omuhle. Gcina kude nokushisa kanye nemithombo yokushisa. Gcina endaweni eyomile, epholile. Gcina kude nama-Oxidizer. Izinyathelo zobuchwepheshe/Izinyathelo Zokuqapha Gcina kude namalangabi avulekile, izindawo ezishisayo kanye nemithombo yokushisa.

    Imibuzo Evame Ukubuzwa

    I-foam yami eguquguqukayo inomthamo ophansi wokuthwala umthwalo. I-TEDA ingayithuthukisa kanjani?

    I-TEDA iqhuba kakhulu ukusabela kwejeli, ikhulisa i-polymer modulus kanye nokuqina kwe-foam ngobuningi obufanayo.

    Iyiphi indlela engcono kakhulu yokusebenzisa i-TEDA eqinile emgqeni we-slabstock oqhubekayo?

    Yincibilikise ku-DPG (isisombululo esingu-33% = MOFAN 33LV) ukuze kulinganiswe uketshezi; i-TEDA eqinile ingabangela ukuvaleka kwamaphampu.

    Igwebu lami elibunjiwe linesikhumba esijiyile kanye nomongo othambile. Ngingalinganisa kanjani?

    Nciphisa i-TEDA ngo-0.05–0.1 phr bese ufaka i-MOFAN A1 encane ukuvula amaseli nokuthambisa isikhumba.

    Ingabe i-TEDA ingasetshenziswa kuma-laminate e-polyisocyanurate (PIR)?

    Yebo, kodwa kuphela njenge-co-catalyst ene-trimer catalyst enamandla njenge-TMR-30 ukuze kugwenywe ukuwohloka okungaphelele.

    Ngifuna ukusheshisa ukususwa kwe-demolding ngefomula ye-foam enamandla okuqina. Iyini i-TEDA range esebenzayo?

    I-0.3–0.6 phr (i-TEDA esebenzayo) inikeza izikhathi zokubonisa zemizuzu engu-3–4 ekushiseni kwesikhunta okungu-50–60°C.

    Ingabe i-TEDA ibangela ukushisa kwegwebu ezinhlotsheni zamanzi amaningi?

    Kungaba nomthelela ekwakhekeni kwangaphakathi kwe-exotherm; gcina i-TEDA ngaphansi kwama-0.4 phr bese usebenzisa ama-antioxidants.

    Ngingalinciphisa kanjani iphunga elivamile le-"amine" ku-foam yefenisha ngaphandle kokulahlekelwa umsebenzi?

    Sebenzisa isixazululo se-TEDA ku-solvent engenaphunga eliningi njenge-DPG (MOFAN 33LV) bese usula igwebu ngemva kokupholisa amahora angu-24 endaweni enomoya.

    Izingxenye zami ze-elastomer azikapheleli kahle ezigabeni ezijiyile. Ingabe i-TEDA ingasiza?

    Yebo, engeza u-0.2–0.4 phr ukuqinisekisa ukuthi iqine ngokuphelele nge-cross-section; ayizweli kakhulu kumswakama kune-tin catalysts.

    Ingabe i-TEDA iyahambisana nama-polyether polyol anemisebenzi ehlukene?

    Kuxutshwa ngokuphelele nazo zonke izinhlobo ze-polyether ezijwayelekile kanye ne-polyester polyols; akukho ukuhlukaniswa kwesigaba.

    Iyiphi inhlanganisela ye-catalyst enikeza izindleko/ukusebenza okuhle kakhulu kwe-foam ejwayelekile eguquguqukayo?

    Inhlanganisela ye-TEDA (0.25 phr) + MOFAN A1 (0.08 phr) iyindlela yokusebenza embonini.
