Imikoreshereze y'ibicuruzwa
HQEE ni impuzandengo ya aromatic diol yagura. Irashobora kunonosora ibintu, gukomera, kwihanganira imiterere ya MDI-polyurethane elastomers. HQEE / MDI ni PU elastomer ikurikirana MOCA / TDI. Ibicuruzwa byarangiye nka: kashe ya peteroli, ipine ya forklift, umukandara wa convoyeur, kashe ya hydraulic kashe hamwe nibindi bicuruzwa byinshi bya PU.
LCU elastomers isaba ibice bibiri byingenzi: prepolymer yarangiye hamwe nitsinda rya isocyanate rikora hamwe na hydrogène ikora itagabanije. Prepolymer nigicuruzwa gishingiye ku myitwarire ya polyester cyangwa polyether hamwe na isocyanate (TDI, MDI, ADI). Kwagura urunigi mubisanzwe ni urunigi rugufi rwa diamine cyangwa diol. MDI prepolymers isanzwe yongerewe hamwe na diol.
Ububiko nububiko
Ipaki:
25kg / ingoma ya karato cyangwa nkibisabwa.
Icyitonderwa: Ibigize imiti nubunini birashobora gutezimbere ibyifuzo byabakiriya
Ububiko:
Komeza gufunga cyane. HQEE ni hygroscopique kandi izahindura ibara munsi yizuba. Komeza gufunga cyane kandi ubike ahantu uhumeka. Irinde ubushuhe n'izuba
Kurinda umutekano
Icyitonderwa cyo gufata neza umutekano
Gukorera ahantu hafite umwuka mwiza. Wambare imyenda ikingira. Irinde guhura n'uruhu n'amaso. Irinde gushiraho umukungugu na aerosole. Koresha ibikoresho bidacana. Irinde umuriro uterwa na electrostatike isohoka.
