Cov khoom siv
HQEE yog symmetrical aromatic diol chain extender. Nws tuaj yeem txhim kho tensile, hardness, resilience zog rau MDI-polyurethane elastomers. HQEE/MDI yog PU elastomer series parallels MOCA/TDI. Cov khoom tiav xws li: roj zoo seals, forklift log tsheb, conveyor siv, hydraulic lub tog raj kheej ntsaws ruaj ruaj thiab ntau lwm yam khoom PU.
LCU elastomers xav tau ob lub hauv paus ntsiab lus: lub prepolymer raug txiav nrog cov pab pawg isocyanate reactive thiab cov khoom siv ua haujlwm hydrogen-terminated chain extender. Prepolymer yog ib yam khoom raws li cov tshuaj tiv thaiv ntawm polyester los yog polyether nrog isocyanate (TDI, MDI, ADI). Cov saw extender feem ntau yog luv luv ntawm diamine lossis diol. MDI prepolymers feem ntau txuas nrog diols.
Ntim Thiab Cia
Pob:
25kg / carton nruas lossis raws li koj xav tau.
Lus Cim: Cov tshuaj muaj pes tsawg leeg thiab qhov loj tuaj yeem ua kom zoo los ntawm cov neeg siv khoom xav tau
Cia:
Khaws kaw kom nruj. HQEE yog hygroscopic thiab yuav hloov xim nyob rau hauv tshav ntuj. Khaws kom nruj thiab khaws cia rau hauv qhov chaw ventilated. Cia kom deb ntawm noo noo thiab tshav ntuj
Kev Tiv Thaiv Kev Nyab Xeeb
Kev ceev faj rau kev nyab xeeb
Tuav nyob rau hauv qhov chaw zoo ventilated. Hnav khaub ncaws tiv thaiv kom haum. Tsis txhob kov ntawm daim tawv nqaij thiab qhov muag. Tsis txhob tsim cov hmoov av thiab aerosols. Siv cov cuab yeej uas tsis muaj teeb meem. Tiv thaiv hluav taws los ntawm electrostatic tawm chav.
