Kugwiritsa Ntchito Zogulitsa
HQEE ndi symmetrical onunkhira diol chain extender. Itha kupititsa patsogolo kulimba, kuuma, kulimba mtima ku MDI-polyurethane elastomers. HQEE/MDI ndi mndandanda wa PU elastomer wofanana ndi MOCA/TDI. Zotsirizidwa monga: zisindikizo zamafuta, matayala a forklift, lamba wotumizira, hydraulic cylinder seals ndi zinthu zina zambiri za PU.
Ma elastomers a LCU amafunikira zigawo ziwiri: prepolymer yothetsedwa ndi magulu a isocyanate komanso cholumikizira cha hydrogen-terminated chain extender. Prepolymer ndi chinthu chotengera momwe polyester kapena polyether yokhala ndi isocyanate (TDI, MDI, ADI). The unyolo extender nthawi zambiri unyolo waufupi wa diamine kapena diol. Ma prepolymer a MDI nthawi zambiri amawonjezedwa ndi ma diol.
Phukusi Ndi Kusungirako
Phukusi:
25kg / katoni ng'oma kapena monga zofunika zanu.
Ndemanga: Kupanga kwa Chemical ndi kukula kwake kumatha kukonzedwa ndi zomwe makasitomala amafuna
Posungira:
Khalani otsekedwa mwamphamvu. HQEE ndi ya hygroscopic ndipo imasintha mtundu ndi kuwala kwa dzuwa. Pitirizani chatsekedwa mwamphamvu ndi kusunga mu mpweya wokwanira malo. Khalani kutali ndi chinyezi ndi kuwala kwa dzuwa
Chitetezo cha Chitetezo
Njira zodzitetezera kuti musagwire bwino
Kusamalira pamalo abwino mpweya wokwanira. Valani zovala zoyenera zodzitetezera. Pewani kukhudzana ndi khungu ndi maso. Pewani kupanga fumbi ndi ma aerosols. Gwiritsani ntchito zida zopanda moto. Pewani moto woyambitsidwa ndi nthunzi ya electrostatic discharge.
