Kunamabhodlela angu-30000 e-RFE esitokweni. Ingakwazi ukulethwa okusheshayo. Inani elengeziwe elinesaphulelo esengeziwe. Ngethemba ukuthi awuphuthelwa.
Uma udinga, wamukelekile ukuxhumana nathi nganoma yisiphi isikhathi

Ngaphezu kwalokho:Inkampani ingacwaninga futhi ithuthukise imikhiqizo emisha ngokwesidingo esikhethekile samakhasimende ethu.
Izici: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 kokunamathelayo, kodwa futhi nezinye izingxenye ezifanele (njenge-resin, i-Antioxygen, i-plasticizer, i-solvent, njll). Lapho sekusondele isikhathi esisebenzayo, ngokuvamile amahora ambalwa noma usuku olulodwa lokusebenza, ukunamathela kuba nzima kakhulu
sebenza, futhi i-viscosity ikhuphuka maduze. 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.
Isitoreji: Sicela ugcinwe embizeni yokuqala evalwe ngaphansi kuka-23℃, imikhiqizo ingagcinwa izinzile izinyanga eziyisithupha. Yonke imikhiqizo yochungechunge lwe-Crosslinker izwela kakhulu kumswakama; izokhiqiza i-carbon dioxide kanye ne-urea engancibiliki ekuphenduleni ngamanzi. Uma ukuchayeka emoyeni noma ekukhanyeni, kuzosheshisa izinguquko zombala wemikhiqizo, Kodwa umsebenzi osebenzayo ngeke uthinteke.
Ukuhlonza izingozi
Umthethonqubo (EC) No 1272/2008
Uketshezi oluvuthayo, Isigaba 2 (H225)
Ubuthi obuqondile besitho esiqondiwe (ukuchayeka okukodwa), Isigaba 3 (H336)
I-Directive 67/548/EEC noma 1999/45/EC
Ivutha kakhulu.
Ukuchayeka ngokuphindaphindiwe kungase kubangele ukomisa kwesikhumba noma ukuqhekeka. Umhwamuko ungabangela ukozela kanye nesiyezi.
Umthethonqubo (EC) No 1272/2008
Izingxenye eziyingozi okufanele zifakwe kuhlu kulebula
i-ethyl acetate
Izitatimende eziyingozi:
H225 Uketshezi oluvutha kakhulu kanye nomhwamuko.
I-H336 Ingabangela ukozela noma isiyezi.
Izitatimende zokuqapha:
P210 Gwema ukushisa/izinhlansi/amalangabi avulekile/izindawo ezishisayo. - Akubhenywa.
P233 Gcina isiqukathi sivalwe ngokuqinile.
P240 Isiqukathi esingaphansi/sebhondi kanye nemishini yokwamukela.
I-P243 Thatha izinyathelo zokuphepha ngokumelene nokukhishwa okumile.
P280 Gqoka amagilavu okuzivikela/izimpahla zokuzivikela/ukuvikela iso/ukuvikela ubuso.
P303 + P361 + P353 UMA ISESIKHUmbeni (noma izinwele): Susa/ Khumula ngokushesha zonke izingubo ezingcolile. Hlanza isikhumba ngamanzi/ishawa.
Izici eziyingozi ezingeziwe nezinto zokulebula:
I-EUH066 Ukuchayeka kaningi kungabangela ukomisa kwesikhumba noma ukuqhekeka. I-EUH204 Iqukethe ama-isocyanate. Meyi
khiqiza ukungezwani komzimba.
