    Iimpawu zeMveliso & neempawu

    I-RFE i-polyisocyanate yi-crosslinker esebenza kakhulu yokuncamathela esekwe kwi-polyurethane, irabha yendalo kunye nerabha ye-Synthesis. I-RFE i-polyisocyanate ikwaluncedo ekuphuculeni ukuncamatheliswa kwezinto ezisekwe kwirabha. Inokusetyenziswa njenge-crosslinker endaweni ye-Bayer's Desmodur RFE.

    Ukusetyenziswa

    I-adhesive-component component kufuneka isetyenziswe kunye nexesha elisebenzayo emva kokubeka i-RFE.
    Ubude bexesha elisebenzayo aluhambelani kuphela nomxholo we-polymer we-adhesive, kodwa kunye namanye amacandelo afanelekileyo (njenge-resin, i-Antioxygen, i-plasticizer, i-solvent, njl.
    Xa kufutshane nexesha elisebenzayo, ngokuqhelekileyo iiyure ezimbalwa okanye usuku olunye lokusebenza, i-adhesive iba nzima kakhulu ukusebenza, kwaye i-viscosity iphakama ngokukhawuleza.
    Ekugqibeleni, iba yijeli engenakuguqulwa. I-adhesive yekhwalithi ye-100, i-Hydroxyl polyurethane (i-akhawunti ye-Polyurethane malunga ne-20%), i-RFE yenza i-4-7. I-rubber ye-chloroprene (i-akhawunti ye-Rubber malunga ne-20%), i-RFE yenza i-4-7.

    Ukupakisha

    Iphakheji: 0.75kg / ibhotile, iibhotile ezingama-20 zizonke kwibhokisi yebhokisi enye, i-180kg / umgqomo, OKANYE ngokwesicelo sabathengi.
    iphakheji-RE-11

    Ugcino

    - Ukugcinwa kwisikhongozeli seCovestro esitywiniweyo sokuqala.
    - Ubushushu bokugcina obucetyiswayo: 10 - 30 °C.
    - Khusela ukufuma, ubushushu kunye nezinto zangaphandle.
    Ulwazi oluphangaleleyo: Ngexesha lothutho kunye nokugcinwa kumaqondo obushushu aphantsi,iidiphozithi zekristale zinokuvela.
    Ezi zinyibilika kwakhona kwiqondo lobushushu begumbi. Iimveliso inomdla kakhulu kumanzi kwaye isabela ngamanzi ukwenza ikhabhoniidioksidi kunye neeurea ezinganyibilikiyo.
    Izikhongozeli ke ngoko kufuneka zigcinwe ngokuqinileyoitywiniwe. Ukungena kwamanzi naluphi na uhlobo (izikhongozeli ezimanzi, ezingenamanziizinyibilikisi, umoya omanzi) kufuneka zithintelwe ngenye indlela ukubunjwa kwekhabhoniidayoksayidi inokubangela ukunyuka okuyingozi koxinzelelo kwizikhongozeli.
    Ukutyhileka emoyeni kunye/okanye ekukhanyeni kuyawuqinisa umbala kodwa oku akunasiphumoiipropathi zokusetyenzwa ngokubanzi.
