Ukusetshenziswa
Isenzo sokuncibilikisa: Uwoyela we-hydrocarbon solvent okhanyayo uyi-solvent enhle ephilayo engancibilikisa izingxenye ezahlukene zokumboza njengama-resins namafutha. Isibonelo, ezimbozweni ze-alkyd resin, ingasiza i-resin ukuthi ihlakazeke ngokulinganayo, okwenza ukuthi i-coating ibe nokugeleza okuhle kanye nezakhiwo zokumboza, okulula emisebenzini yokwakha njengokuxubha nokufutha. Ukulawula isivinini sokomisa: Izinga layo lokuhwamuka lilinganiselwe futhi lingalungisa isikhathi sokomisa sezingubo. Kwezinye izingubo ezidinga ukwakha ifilimu ngokomisa phakathi nesikhathi esithile, uwoyela we-hydrocarbon solvent okhanyayo ungaqinisekisa ukuthi i-coating iyahwamuka phakathi nesikhathi esifanele, ukuze ifilimu yokumboza ikwazi ukwakha izakhiwo ezinhle zomzimba, njengokuqina nokucwebezela. Kuma-lacquers e-nitrocellulose, isiza ekuncibilikiseni i-nitrocellulose futhi yakhe ifilimu efanayo, futhi ingalawula nesivinini sokomisa se-lacquer ukuze igweme ikhwalithi ephansi yefilimu yokumboza ebangelwa ukomisa okusheshayo kakhulu. Ukuncibilikisa uyinki: Njenge-diluent yeyinki, uwoyela we-hydrocarbon solvent okhanyayo unganciphisa i-viscosity yeyinki, okwenza ivumelane kangcono nezidingo zemishini yokuphrinta. Isibonelo, kuma-inki okunyathelisa nge-offset, uwoyela we-solvent ofanele ungalungisa izakhiwo ze-rheological zeyinki, okwenza ukuthi uyinki idluliselwe kahle kusuka epuletini lokunyathelisa iye ezintweni zokunyathelisa ezifana nephepha, okuqinisekisa ukucaca nokugqama kwemibala ekunyatheliseni. Ukuncibilikisa ama-resin nama-pigment: Kungancibilikisa izingxenye ze-resin kuyinki futhi kwenze ama-pigment ahlakazeke ngokulinganayo kuyo. Lokhu kubaluleke kakhulu ekunyatheliseni kombala wekhwalithi ephezulu, ngoba kuphela lapho ama-pigment esatshalaliswa ngokulinganayo lapho imibala ingakhiqizwa khona ngokunembile futhi ithole imiphumela emihle kakhulu yokunyathelisa.
Ukupakisha Nokuthumela
Ukupakisha: 200kg/isigubhu noma ngokwezidingo zamakhasimende.
Ukuthunyelwa: kungokwamakhemikhali avamile futhi kungalethwa ngesitimela, ulwandle kanye nomoya.
Gcina futhi ugcine
Isikhathi sokuphila: Izinyanga ezingama-24 kusukela ngosuku lokwenziwa kwento epakishweni lokuqala elingavulwanga, igcinwe endaweni epholile neyomile kude nokukhanya kwelanga okuqondile, amanzi.
Indawo yokugcina izinto enomoya, Ukomisa okuphansi kwezinga lokushisa, Ihlukaniswe nama-oxidants, ama-acid.
