Isticmaalka Alaabta
HQEE waa fidiyaha silsiladda diol udgoonka summaysan. Waxay hagaajin kartaa xajinta, adkaanta, guryaha adkeysiga MDI-polyurethane elastomers. HQEE/MDI waa taxane elastomer PU barbar socda MOCA/TDI. Alaabooyinka la dhammeeyay sida: xidhmooyinka ceelka saliidda, taayirada fargeetada, suunka wax qaadda, shabbaadaha hydraulic cylinders iyo alaabooyin kale oo badan oo PU ah.
Elastomers LCU waxay u baahan yihiin laba qaybood oo mabda'a ah: prepolymer-ka la joojiyay kooxaha isocyanate fal-celinta iyo fidiyaha silsiladda ee hydrogen-ka-joogsan ee firfircoon. Prepolymer waa badeecad ku salaysan falcelinta polyester-ka ama polyeter-ka leh isocyanate (TDI, MDI, ADI). Silsiladda fidiyaha badanaa waa silsilad gaaban oo diamine ama diol ah. MDI prepolymers waxaa badanaa lagu kordhiyaa diols.
Xidhmada iyo Kaydinta
Xidhmada:
25kg/ durbaan kartoon ama sida shuruudahaaga.
Fiiro gaar ah: Halabuurka kiimikada iyo cabbirka waxaa lagu hagaajin karaa shuruudaha macaamiisha
Kaydinta:
Si adag u xidh. HQEE waa hygroscopic waxayna bedeli doontaa midabka qorraxda hoosteeda. Si adag u xidh oo ku kaydi meel hawo leh. Ka fogow qoyaanka iyo iftiinka qorraxda
Ilaalinta Badbaadada
Taxadarrada si badbaado leh loo maareeyo
Wax ka qabashada meel hawo fiican leh. Xiro dhar ilaalin ku habboon. Ka fogow taabashada maqaarka iyo indhaha. Iska ilaali samaynta boodhka iyo hawada hawada. Isticmaal aaladaha aan hurinta lahayn. Ka hortag dabka ka dhasha uumiga dareeraha korantada.
