Polyaspartic Coating Technology
Iyo chemistry yakavakirwa pakuita kwealiphatic polyisocyanate uye polyaspartic ester, iri aliphatic diamine. Iyi tekinoroji yakatanga kushandiswa mune akajairwa maviri-component polyurethane-inotakura coating maumbirwo nekuti ma polyaspartic esters akanakisa reactive diluents kune yakakwira solids polyurethane coatings.
Zvimwe zvichangobva kuitika mu polyaspartic coating tekinoroji zvakanangana nekuwana yakaderera kana pedyo-zero VOC coatings apo polyaspartic ester ndiyo chikamu chikuru checo-reactant yekuita ne polyisocyanate. Iyo yakasarudzika uye inogadziriswa reactivity ye polyaspartic esters inobvumira dhizaini yekukurumidza-kurapa majasi akagadzirirwa kune zvinodiwa zvekushandisa. Iyo inokurumidza kuporesa chimiro cheaya machira anogona kupa akakosha, ekuchengetedza mari kugadzirwa kwekuvandudza, pamwe nepamusoro-kuvaka, yakaderera-yekushisa kurapa, uye abrasion uye corrosion kuramba.
Iro zita rekuti polyaspartics rave mukurumbira munguva pfupi yapfuura pakati pevagadziri muindasitiri nekuda kwekuda kuisiyanisa kubva ku polyureas uye polyurethanes. Netsanangudzo, polyaspartic inonzi aliphatic polyurea nekuti ndiko kuita kwealiphatic polyisocyanate ine polyaspartic ester - inova aliphatic diamine. Nekudaro, ma polyaspartic coatings akasiyana zvakanyanya mune ese ari maviri ekushandisa uye nekuputira maitiro ekuita kubva kune akajairwa polyureas. Semuenzaniso, polyaspartics inobvumira mugadziri kudzora mwero wekuita uye kurapwa, nekudaro, potlife yemusanganiswa wezvikamu zviviri inogona kubva pamaminitsi mashanu kusvika maawa maviri. Nepo nzira dzekupfapfaidza dzekushandisa dzinosanganisira kushandiswa kweplural component spray equipment, akawanda maapplication anogona kuiswa neajairira sprayers, zvichiita kuti application isanyanya kunetsa uye isingaite kukanganisa.
Polyaspartic tekinoroji iri padyo mumashandisirwo ayo uye maitiro ekuita kune 2-chikamu aliphatic polyurethane coatings. Inowanzoshandiswa sejasi repamusoro nekuda kwechimiro chayo chisina kutsvuka. Asi, panowo, pane misiyano inocherekedza. Iyo polyaspartic coatings, semuenzaniso, inogona kugadzirwa kusvika kune yakanyanya kuoma (70-100% solids) uye inoshandiswa pakakwirira firimu inovaka (kusvika 15 mils WFT mujasi rimwe chete) pane yakajairwa maviri-component aliphatic polyurethanes. Nekuti polyaspartics inokurumidza kuomesa kupfuura yakajairwa aliphatic polyurethanes, inowanzoshandiswa mumashandisirwo apo kurapwa nekukurumidza kunoreva kuvandudzwa kwechigadzirwa mukushanda kwekupenda.
