Application Of Ddi In Textile Fabric

Diisocyanate (DDI) diisocyanate na musamman na aliphatic tare da 36 carbon atom dimer fatty acid kashin baya.Tsarin yana ba DDI mafi kyawun sassauci da mannewa fiye da sauran isocyanates aliphatic.DDI yana da kaddarorin ƙarancin guba, babu rawaya, narke a cikin mafi yawan abubuwan kaushi, ƙarancin ruwa da ƙarancin danko.DDI wani nau'i ne na ayyuka guda biyu Isocyanate, yana iya aiki tare da mahaɗan hydrogen guda biyu ko fiye don yin polymer.DDI za a iya amfani da a m roka propellant, masana'anta karewa, takarda, fata da masana'anta repellent, itace preservative magani, lantarki tukunyar jirgi da kuma shirye-shiryen na musamman kaddarorin na polyurethane (urea) elastomers, m da sealant, da dai sauransu.

A cikin masana'antar Fabric, DDI yana nuna kyakkyawan yanayin aikace-aikacen a cikin abubuwan da ke hana ruwa da laushi zuwa yadudduka.Ba shi da ƙarancin kula da ruwa fiye da isocyanates na ƙanshi kuma ana iya amfani dashi don shirya emulsion mai tsayayyen ruwa.
