Desmodur RE:Funda malunga nokusetyenziswa kunye neenzuzo ze-isocyanates
Desmodur REyimveliso yecandelo le-isocyanate, ekhethwe ngokukodwa i-CAS 2422-91-5. I-Isocyanates ziyizithako eziphambili kwimveliso yeemveliso ezahlukeneyo ze-polyurethane, kwaye i-Desmodur RE ayinjalo. Eli nqaku lijolise ekunikeni ukuqonda okunzulu kwe-Desmodur RE, ukusetyenziswa kwayo kunye neenzuzo ezinikezelayo kwizicelo ezahlukeneyo.
Desmodur REyi-aliphatic polyisocyanate esekwe kwi-hexamethylene diisocyanate (HDI). Isetyenziswe ngokuyinhloko njengecandelo elinzima kwi-polyurethane ene-stable-stable coatings kunye ne-adhesive formulations. I-chemistry ekhethekileyo ye-Desmodur RE yenza ukuba ibe yinto efanelekileyo kwizicelo ezifuna iingubo eziphezulu zokusebenza kunye nemozulu ebalaseleyo kunye nokuchasana kweekhemikhali. Ukongeza, ukuhambelana kwayo kunye neentlobo ezahlukeneyo ze-polyols kunye nezinyibilikisiweyo kuphucula ngakumbi ukuguquguquka kwayo kwiindlela ezahlukeneyo.
Enye yeenzuzo eziphambili zeDesmodur REkukwazi kwayo ukunika ukuqina okugqwesileyo kunye nokuxhathisa kwe-UV kwiingubo. Oku kuyenza ukuba ifaneleke ngokukodwa kwizicelo zangaphandle, apho ukuvezwa kweemeko ezibuhlungu zokusingqongileyo kunokunciphisa ukusebenza kweengubo zendabuko. Nokuba isetyenziswa kwiingubo zokugquma iimoto, ukugcinwa kwemizi-mveliso okanye ukugqiba uyilo, iDesmodur RE idlala indima ebalulekileyo ekuphuculeni ubomi obude kunye nenkangeleko yeendawo ezigqunyiweyo.
Ukongeza kwindima yayo kwiingubo, i-Desmodur RE iphinda isetyenziswe kwimveliso ye-adhesives ephezulu. Iipropati zayo zokunyanga ngokukhawuleza kunye nokunamathela ngokugqwesileyo kwiintlobo ezahlukeneyo ze-substrates zenza ukuba ibe yinto ebalulekileyo kwi-adhesives yesakhiwo, i-laminating adhesives kunye ne-sealant formulations. I-Desmodur RE adhesives iyakwazi ukumelana noxinzelelo lomatshini kunye nezinto zokusingqongileyo, zibenza ukhetho lokuqala lokufuna izicelo zokudibanisa kumashishini ahlukeneyo.
Ukwengeza,Desmodur REinika abaqulunqi amandla okulungelelanisa ngokuguquguqukayo iipropati ze-polyurethane yokwambathisa kunye ne-adhesives kwiimfuno ezithile. Ngokulungelelanisa umlinganiselo wokuqulunqa kunye nokubandakanya i-Desmodur RE, uluhlu olubanzi lweempawu zokusebenza lunokufezekiswa, kubandakanywa ubunzima, ukuguquguquka kunye nokuchasana kweekhemikhali. Eli nqanaba lokwenziwa ngokwezifiso lenza abavelisi ukuba bahlangabezane neemfuno ezahlukeneyo zabasebenzisi bokugqibela kumacandelo asusela kwiimoto kunye ne-aerospace ukuya kulwakhiwo kunye neziseko.
Kubalulekile ukuqaphela ukuba ngelixaDesmodur REibonelela ngeenzuzo ezininzi malunga nokusebenza kunye nokuguquguquka, ngenxa yendalo esebenzayo ye-isocyanates, ukuphathwa ngokufanelekileyo kunye nokhuseleko kufuneka kuqwalaselwe. Ukuvezwa kwi-isocyanates kunokubeka ingozi kwimpilo, ngoko ke kubalulekile ukulandela izikhokelo zokhuseleko ezicetyiswayo kunye nokusebenzisa izixhobo ezifanelekileyo zokukhusela xa uphethe i-Desmodur RE kunye nezinye iimveliso ezisekelwe kwi-isocyanate.
Isishwankathelo,Desmodur REsisithako esibalulekileyo ekuqulunqweni kweengubo eziphezulu ze-polyurethane kunye ne-adhesives. Ukuqina kwayo okukhethekileyo, ukuxhathisa kwe-UV kunye nokuguquguquka kwenza ukuba ibe sisithako esiyimfuneko kwimveliso yeengubo kunye ne-adhesives kwizicelo ezahlukeneyo. Ngokuqonda ukusetyenziswa kunye neenzuzo zeDesmodur RE, abavelisi kunye nabasebenzisi bokugqibela banokusebenzisa amandla abo okudala imveliso ehlala ixesha elide, ehlala ixesha elide kunye nekhwalithi ephezulu ye-polyurethane. Nangona kunjalo, xa usebenza ngeemveliso ze-isocyanate, kubalulekile ukubeka phambili amanyathelo okhuseleko ukuqinisekisa impilo yabasebenzi kunye nokusingqongileyo.
