Dimeryl Diisocyanate DDI nziza cyane CAS NO. 68239-06-5
OYA ni diisocyanate yihariye ya aliphatic ishobora gukoreshwa mu gutegura polymers zifite ibintu birimo hydrogen ikora. Ni ikintu gifite uruhererekane rurerure gifite uruti rw'umugongo rwa aside fatty ya 36-dimer dimer. Imiterere y'uruhererekane nyamukuru itanga OYA bworoshye cyane, kudapfa amazi no kugira uburozi buke ku zindi isocyanate za aliphatic. OYA Ni amazi afite ubushyuhe buke kandi ashobora gushonga mu bintu byinshi bidafite ubushyuhe. Kubera ko ari isocyanate ya alifatiki, ifite imiterere yo kudahinduka umuhondo. Ifite ibyiza byinshi byo kuba uburozi buke, byoroshye gukoresha, ishobora gushonga mu bintu byinshi bidafite uburozi, igihe cyo kuyigenzura no kuyigabanya amazi. Ni ubwoko busanzwe bwa isocyanate y’icyatsi kibisi ishobora kongera gukoreshwa, ishobora gukoreshwa cyane mu kurangiza imyenda, elastomers, kole n’ibifunga, irangi, irangi n’ibindi bikorwa bya gisirikare n’ibya gisivili.
1. Imyenda: DDI yacu ifite amazi yoroshye kuyihinduramo amazi, byatumye imyenda iba yoroshye, yoroshye kandi idapfa amazi.
2. Resin ya PU na resin ya Polyurea, hakoreshejwe DDI, ishobora kuba ifite imiterere idahinduka umuhondo, irakomera cyane, kandi irakora neza, irakomeye cyane, irakoresha amazi make, kandi irinda kwangirika neza, irwanya imiti ihumanya ikirere, kandi irinda ubushyuhe buke.
3. Gira icyo uvuga kuri HTTPB Kugira ngo ihuze neza kandi ikore neza, PU ikorwa ishobora kuba ikomeye cyane, nta gikoresho cya pulasitiki gikenewe.
4. Gusiga. Gusiga polyurea ya DDI ifite imbaraga zo gukurura kandi idashobora guhindagurika, byoroshye gufata ku byuma n'ibiti bidacitse.
