    Izakhiwo zomkhiqizo nezici

    I-RFE i-polyisocyanate iyi-crosslinker esebenza kahle kakhulu yokunamathela esekelwe ku-polyurethane, irabha yemvelo kanye nerabha ye-Synthesis. I-RFE polyisocyanate iyasiza futhi ekuthuthukiseni ukunamathela kwezinto ezisekelwe erabha. Ingasetshenziswa njenge-crosslinker esikhundleni se-Bayer's Desmodur RFE.

    Ukusetshenziswa

    Okunamathelayo okunezingxenye ezimbili kufanele kusetshenziswe nesikhathi esisebenzayo ngemuva kokufaka i-RFE.
    Ubude besikhathi esisebenzayo abuhlobene kuphela nokuqukethwe kwe-polymer kokunamathela, kodwa futhi nezinye izingxenye ezifanele (njenge-resin, i-Antioxygen, i-plasticizer, i-solvent, njll.
    Uma sekusondele isikhathi esisebenzayo, ngokuvamile amahora ambalwa noma usuku olulodwa lokusebenza, ukunamathela kuba nzima kakhulu ukusebenza, futhi i-viscosity iphakama ngokushesha.
    Ekugcineni, iba ijeli engaphenduki. I-adhesive yekhwalithi engu-100, i-Hydroxyl polyurethane (i-akhawunti ye-Polyurethane cishe engama-20%), i-RFE yenza u-4-7. Irabha ye-Chloroprene (I-akhawunti yerabha cishe i-20%), i-RFE yenza i-4-7.

    Ukupakisha

    Iphakheji: 0.75kg / ibhodlela, amabhodlela angama-20 esebhokisini elilodwa lebhokisi, 180kg / umgqomo, NOMA ngokusho kwesicelo samakhasimende.
    iphakheji-RE-11

    Isitoreji

    - Isitoreji esitsheni sokuqala se-Covestro esivaliwe.
    - Izinga lokushisa elinconyiwe lokugcina: 10 - 30 °C.
    - Vikela umswakama, ukushisa nezinto zangaphandle.
    Ulwazi olujwayelekile: Ngesikhathi sokuthutha nokugcinwa emazingeni okushisa aphansi,ama-crystalline deposits angase akheke.
    Lezi ziphinde zincibilike ezingeni lokushisa legumbi. Iumkhiqizo uzwela kakhulu kumswakama futhi usabela ngamanzi ukwenza ikhabhonii-dioksidi kanye ne-insoluble ureas.
    Ngakho-ke izitsha kufanele zigcinwe ziqinileivaliwe. Ukungena kwamanzi nganoma yiluphi uhlobo (iziqukathi ezimanzi, ezingenamanziizinto ezincibilikisayo, umoya omanzi) kumele zigwenywe njengoba kungenjalo ukwakheka kwekhabhoniI-dioksidi ingase ibangele ukwenyuka okuyingozi komfutho ezitsheni.
    Ukuchayeka emoyeni kanye/noma ekukhanyeni kukhulisa ukushintsha kombala kodwa lokhu akunawo umthelelaizakhiwo zokucubungula ngokujwayelekile.
