Polyaspartic Coating Technology
Ikhemistri isuselwe ekuphenduleni kwe-aliphatic polyisocyanate kanye ne-polyaspartic ester, okuyi-aliphatic diamine. Lobu buchwepheshe ekuqaleni babusetshenziswa ekuhlanganiseni okujwayelekile kwezingxenye ezimbili ze-polyurethane ezithwala i-solvent ngenxa yokuthi ama-ester e-polyaspartic angama-diluent asebenzayo asebenza kahle kakhulu ezinto eziqinile ze-polyurethane ezinengilazi. I-ester iyingxenye eyinhloko ye-co-reactant yokusabela nge-polyisocyanate. Okuyingqayizivele futhiFunda kabanzi …
Iyini i-Polyurea Coating kanye ne-Polyurethane Coatings
I-Polyurea Coating kanye ne-Polyurethane Coatings I-polyurea enamathela I-polyurea ngokuyisisekelo iyisistimu enezingxenye ezimbili esekelwe ku-Amine enqanyuliwe i-prepolymer exhunywe ne-Isocyanate eyenza ukuxhumana kwe-urea. Ukuphambana phakathi kwama-polymer asebenzayo kwenzeka ngesivinini esisheshayo kuzinga lokushisa elizungezile. Ngokuvamile lokhu kusabela akudingi noma iyiphi i-catalyst. Njengoba i-Pot-life ye-coating enjalo ingaphakathi kwemizuzwana; uhlobo olukhethekile lwe-Plural Isibhamu sokufafaza sengxenye siyadingeka ukwenza isicelo. I-coatings ingakha kuze kufike ku-500 kuyaFunda kabanzi …
Iyini i-polyurethane ene-Moisture-cured
Iyini i-polyurethane ene-polyurethane ene-Moisture-cured iyingxenye eyodwa ye-polyurethane ukuthi ukwelashwa kwayo kuqala umswakama wemvelo. I-polyurethane elapheka ngokuswakama ngokuyinhloko iqukethe i-pre-polymer enqanyuliwe isocyanate. Izinhlobo ezahlukahlukene ze-pre-polymer zingasetshenziswa ukuhlinzeka ngempahla edingekayo. Isibonelo, ama-polyether polyether polyols aphethwe yi-isocyanate asetshenziselwa ukunikeza ukuguquguquka okuhle ngenxa yezinga lokushisa eliphansi lokushintsha kwengilazi. Ukuhlanganisa ingxenye ethambile, njenge-polyether, nengxenye eqinile, njenge-polyurea, inikeza ubulukhuni obuhle nokuguquguquka kwezingubo. Ngaphezu kwalokho, izakhiwo nazo zilawulwa nguFunda kabanzi …
Amasu amabili okuklama ama-coatings anokumelana okuhlukile kwe-mar
Kunamasu amabili atholakalayo okuklama ama-coatings anokumelana okukhethekile kwe-mar. Zingenziwa ziqine ngokwanele ukuthi into eganayo ingangeni kude phezulu; noma Angenziwa anwebeka ngokwanele ukuze alulame ngemva kokususwa kokucindezeleka okulimazayo. Uma isu lokuqina likhethiwe, ukugqoka kufanele kube nobulukhuni obuncane. Kodwa-ke, ukugqoka okunjalo kungase kuhluleke ngokuphuka. Ukuvumelana nezimo kwefilimu kuyisici esibalulekile esithonya ukumelana nokuqhekeka. Ukusetshenziswa kwe-4-hydroxybutyl acrylate esikhundleni seFunda kabanzi …
