    Ukuphatha kunye nokugcina

    Amanyathelo okuzikhusela xa uphatha izinto ngendlela ekhuselekileyo. Kuphephe ukudibana namehlo. Sebenzisa izixhobo zokuzikhusela. Xa usebenzisa, musa ukutya, ukusela okanye ukutshaya. Imiqathango yokugcina izinto ngendlela ekhuselekileyo, kuquka naziphi na izinto ezingahambelaniyo. Musa ukugcina kufutshane nee-asidi. Gcina kwizikhongozeli zentsimbi ezibekwe ngaphandle, ngaphezulu komhlaba, kwaye zijikelezwe zii-dikes ukuze kugcinwe ukuchitheka okanye ukuvuza. Gcina izikhongozeli zivalwe ngokuqinileyo kwindawo eyomileyo, epholileyo nengena umoya. Gcina kude nobushushu kunye nemithombo yokutsha. Gcina kwindawo eyomileyo, epholileyo. Gcina kude ne-Oxidizers. Amanyathelo obuchwephesha/Amanyathelo okhuseleko Gcina kude namalangatye avulekileyo, iindawo ezishushu kunye nemithombo yokutsha.

    FAQ

    Ifoam yam eguquguqukayo ayinamandla okuthwala umthwalo. Ingayiphucula njani iTEDA?

    I-TEDA iqhuba ngamandla ukusabela kwejeli, inyusa imodulus yepolymer kunye nobunzima befoam kubuninzi obufanayo.

    Yeyiphi indlela engcono yokusebenzisa i-TEDA eqinileyo kumgca we-slabstock oqhubekayo?

    Yinyibilikise kwi-DPG (33% isisombululo = MOFAN 33LV) ukuze idosi ibe lulwelo; i-TEDA eqinileyo inokubangela ukuvaleka kweepompo.

    Igwebu lam elibunjiweyo linolusu oluqinileyo kunye nomongo othambileyo. Ndingalilinganisa njani?

    Nciphisa i-TEDA nge-0.05–0.1 phr uze wongeze i-MOFAN A1 encinci ukuvula iiseli kunye nokuthambisa ulusu.

    Ngaba i-TEDA ingasetyenziswa kwi-polyisocyanurate (PIR) laminates?

    Ewe, kodwa kuphela njenge-co-catalyst ene-trimer catalyst enamandla efana ne-TMR-30 ukuze kuthintelwe ukubola okungaphelelanga.

    Ndifuna ukukhawulezisa ukwenziwa kwe-demolding kwifomyula ye-foam ekwaziyo ukumelana nobunzima obuphezulu. Luluphi uluhlu lwe-TEDA olusebenzayo?

    I-0.3–0.6 phr (i-TEDA esebenzayo) inika amaxesha okubonisa emizuzu emi-3–4 kubushushu bomngundo obungama-50–60°C.

    Ngaba i-TEDA ibangela ukutsha kwegwebu kwiifomyula ezinamanzi amaninzi?

    Inokuba negalelo kwi-exotherm yangaphakathi; gcina i-TEDA ingaphantsi kwe-0.4 phr kwaye usebenzise ii-antioxidants.

    Ndingayinciphisa njani ivumba eliqhelekileyo le-"amine" kwi-foam yefenitshala ngaphandle kokulahlekelwa ngumsebenzi?

    Sebenzisa isisombululo se-TEDA kwisinyibilikisi esingenavumba liphantsi njenge-DPG (MOFAN 33LV) kwaye emva kokucoca igwebu kangangeeyure ezingama-24 kwindawo enomoya.

    Iindawo zam ze-elastomer azinawo umgubo owaneleyo kwiindawo ezixineneyo. Ngaba i-TEDA inganceda?

    Ewe, yongeza i-0.2–0.4 phr ukuqinisekisa ukuba iphiliswa ngokupheleleyo; ayichukumisi kangako kumswakama kunee-tin catalysts.

    Ngaba i-TEDA iyahambelana nee-polyether polyols ezinemisebenzi eyahlukeneyo?

    Ixutywa ngokupheleleyo nazo zonke iipolyether ezisemgangathweni kunye neepolyester polyols; akukho kwahlukana kwesigaba.

    Yeyiphi indibaniselwano ye-catalyst enika ixabiso/ukusebenza okungcono kwi-foam eguquguqukayo eqhelekileyo?

    Umxube we-TEDA (0.25 phr) kunye ne-MOFAN A1 (0.08 phr) yeyona nto isebenzayo kushishino.
