Ikhwalithi ephezulu ye-Dimeryl Diisocyanate DDI CAS NO. 68239-06-5
CHA iyi-aliphatic disocyanate eyingqayizivele engasetshenziswa ukulungisa ama-polymers anezinhlanganisela eziqukethe i-hydrogen esebenzayo. Kuyinhlanganisela enamaketanga amade enomgogodla we-36-carbon dimer fatty acid. Isakhiwo seketango eliyinhloko sinikezaCHAukuguquguquka okuphakeme, ukumelana namanzi kanye nobuthi obuphansi kwamanye ama-aliphatic isocyanate.CHA iwuketshezi olune-viscosity oluphansi oluncibilika kalula kuzincibilikisi eziningi ezitholakala endaweni epholile noma ezingezona ezimhlophe. Ngoba i-aliphatic isocyanate, inezici zokungaphuzi. Inezinzuzo eziningi zobuthi obuphansi, kulula ukuyisebenzisa, inyibilika kuzincibilikisi eziningi, isikhathi sokusabela esilawulekayo kanye nokuzwela okuphansi kwamanzi. Kuwuhlobo olujwayelekile lwe-biorenewable olukhethekile lwe-isocyanate oluhlaza, olungasetshenziswa kabanzi ekuqedeni indwangu, ama-elastomer, ama-adhesive nama-sealants, ama-coatings, ama-inki nezinye izinkundla zezempi nezomphakathi.
1. Indwangu: i-DDI yethu ngamanzi kalula ibe i-emulsion enamanzi, eyenza indwangu ibushelelezi, ithambile, futhi ingangeni manzi.
2. I-PU resin kanye ne-Polyurea resin, kusetshenziswa i-DDI ingaba ne-preformance yokungaphuzi, ukuqina okuhle kakhulu, nokunwebeka, ukuqina okuphezulu, amanzi aphansi anengqondo, nokunqanda ukuthuthumela okungcono, i-anti-chemical solvent, kanye nezinga lokushisa eliphansi.
3. Sabela ngeI-HTTPBukuze kube ukuhambisana okuhle kakhulu nokusebenza kabusha, i-PU ekhiqiziwe ingaba eqinile ephansi ngokungavamile, asikho isidingo se-ejenti yepulasitiki.
4. Ukugqoka. I-DDI i-polyurea enamathela ngamandla aqinile okuqinile kanye nobufakazi besimo sezulu, okunamathela kalula ensimbi nasezinkuni ngaphandle kokuphuka.
