Tulaga maualuga Dimeryl Diisocyanate DDI CAS NO. 68239-06-5
LEAI o se aliphatic diisocyanate tulaga ese e mafai ona faʻaaogaina e saunia ai polymers faʻatasi ai ma mea faʻapipiʻi o loʻo i ai le hydrogen malosi. O se fa'aputuga o filifili umi ma se ivi ga'o ga'o 36-carbon dimer tua. O le fausaga filifili autu e maua aiLEAIfetuutuunai maualuga, tetee vai ma maualalo oona i isi isocyanates aliphatic.LEAI ose vai viscosity maualalo e faigofie ona solu i le tele polar po o non-polar solvents. Ona o le aliphatic isocyanate, ei ai uiga o le le samasama. E tele mea lelei o le maualalo o le oona, faigofie ona faʻaoga, solu i le tele o solvents, faʻatonuina taimi tali ma le maualalo o le vai. O se mea masani lanu meamata biorenewable isocyanate faapitoa eseese, lea e mafai ona faʻaaogaina lautele i le faʻamaeʻaina o ie, elastomers, faʻapipiʻi ma faʻamaufaʻailoga, faʻapipiʻi, inks ma isi vaega o le militeri ma le va o tagata.
1. Ie: tatou DDI ma vai faigofie e avea aqueous emulsion, lea na faia ai le ie lamolemole, gentile, ma vai-faamaonia.
2. PU resin ma Polyurea resin, faʻaaogaina le DDI e mafai ona faʻatasi ma le faʻamuamua o le le samasama, faʻaleleia lelei, ma le faʻalauteleina, maualuga maualuga, maualalo le vai maaleale, ma sili atu anti-abrasivenesss, solvent anti-kemikolo, ma anti-maualalo vevela.
3. Tali atu maHTPBina ia sili ona fetaui lelei ma le gaoioi, o le PU gaosia e mafai ona tulaga ese le malosi, leai se mea e manaʻomia ai se palasitika.
4. Ufiufi. DDI polyurea faʻapipiʻi ma le malosi sili ona malosi ma faʻamaoniga o le tau, lea e faigofie ona pipii i uʻamea ma laupapa e aunoa ma le gau.
