Metsoalle e meng e kile ea thulana le boemo bo joalo. Ha ke tsebe lebaka. 'Mala oa mokotla ona oa papali o felile ka mor'a ho sebelisoa nako e telele. Qalong ke ne ke nahana hore ke ntho e ke keng ea fela, empa joale e se e felile. Kahoo a re hlahlobeng mabaka a hore na ke hobane’ng. Lebaka la ho fela ha mekotla ea lipapali tsa EVA ke lefe?
Lintho tse amang ho fela ha polasetikiEVAlihlahisoa. Ho fela ha lihlahisoa tse mebala ea polasetiki ho amana le ho hanyetsa khanya, ho hanyetsa oksijene, ho hanyetsa mocheso, ho hanyetsa acid le alkali ea li-pigments le dae, le litšobotsi tsa resin e sebelisitsoeng. Ho ea ka maemo a ts'ebetso le litlhoko tsa ts'ebeliso ea lihlahisoa tsa polasetiki, thepa e boletsoeng ka holimo ea li-pigments tse hlokahalang, lidae, li-surfactants, li-dispersants, li-resin tse tsamaisang botsofali le li-additives tse thibelang botsofali li lokela ho hlahlojoa ka botlalo nakong ea tlhahiso ea masterbatch pele ho khetho.
1. Acid le alkali resistance Ho fela ha lihlahisoa tsa polasetiki tse mebala ho amana le khanyetso ea lik'hemik'hale ea colorant (acid le alkali resistance, redox resistance).
Mohlala, bofubelu ba molybdenum chromium bo hanana le asiti e hlapollang, empa e na le kutloelo-bohloko ho alkali, 'me bosehla ba cadmium ha bo hanyetsane le asiti. Li-pigment tsena tse peli le resin ea phenolic li na le phello e matla ea ho fokotsa mebala e itseng, e ama ka botebo ho hanyetsa mocheso le ho hanyetsa boemo ba leholimo ba mebala le ho baka ho fela.
2. Antioxidation: Li-pigments tse ling tsa manyolo li nyamela butle-butle ka lebaka la ho senyeha ha li-macromolecules kapa liphetoho tse ling ka mor'a hore ho be le oxidation.
Ts'ebetso ena e kenyelletsa oxidation ea mocheso o phahameng nakong ea ts'ebetso le oxidation ha o kopana le li-oxidants tse matla (joalo ka chromate e mosehla oa chromium). Ha matša, li-azo pigments le chrome yellow li kopantsoe, 'mala o mofubelu o tla fela butle-butle.
3. Ho tsitsisa ha mocheso oa li-pigment tse thibelang mocheso ho bolela tekanyo ea ho lahleheloa ke boima ba mocheso, ho fifala, le ho fela ha 'mala tlas'a mocheso oa mocheso.
Metsoako ea li-pigment tsa inorganic ke li-oxide tsa tšepe le letsoai, tse nang le botsitso bo botle ba mocheso le ho hanyetsa mocheso o phahameng. Li-pigments tse entsoeng ka metsoako ea lintho tse phelang li tla ba le liphetoho sebopeho sa limolek'hule le ho bola hanyenyane ka mocheso o itseng. Haholo-holo bakeng sa lihlahisoa tsa PP, PA, le PET, mocheso oa ho sebetsa o ka holimo ho 280 ° C. Ha re khetha li-colorants, ka lehlakoreng le leng, re tlameha ho ela hloko ho hanyetsa mocheso oa pigment, 'me ka lehlakoreng le leng, re lokela ho nahana ka nako ea ho hanyetsa mocheso oa pigment. Nako ea ho hanyetsa mocheso hangata ke 4-10 pula. .
