Ka bobeli li-disperants le lubricant ke li-additives tse sebelisoang hangata ho bapisa mebala ea polasetiki.Haeba li-additives tsena li eketsoa lihlahisoa tse tala tsa sehlahisoa, li hloka ho ekeletsoa lihlahisoa tse tala tsa resin ka tekanyo e lekanang le bopaki bo lumellanang le mebala, e le ho qoba phapang ea mebala tlhahisong e latelang.
Mefuta ea li-dispersants ke: mafura a acid polyureas, base stearate, polyurethane, oligomeric sesepa, joalo-joalo Li-dispersants tse sebelisoang ka ho fetisisa indastering ke litlolo.Litlolo li na le thepa e ntle ea ho hasana, 'me li ka boela tsa ntlafatsa thepa ea metsi le hlobo ea polasetiki nakong ea ho bōptjoa.
Lisebelisoa li arotsoe ka lisebelisoa tsa ka hare le tse tsoang ka ntle.Lisebelisoa tsa ka hare li na le tumellano e itseng le li-resin, tse ka fokotsang momahano pakeng tsa liketane tsa limolek'hule tsa resin, tsa fokotsa viscosity ea ho qhibiliha, le ho ntlafatsa metsi.Ho tsamaellana lipakeng tsa setlolo sa kantle le resine, e khomarela bokaholimo ba lesela le qhibilihisitsoeng ho etsa lera la molek'hule e tlotsang, ka hona e fokotsa likhohlano lipakeng tsa resin le lisebelisoa tsa ho lokisa.Li-lubricant li arotsoe haholo ka mekhahlelo e latelang ho latela sebopeho sa tsona sa lik'hemik'hale:
(1)) Sehlopha sa ho chesa joalo ka parafine, boka ba polyethylene, boka ba polypropylene, boka ba micronized, joalo-joalo.
(2) Mafura a mafura a kang stearic acid le base stearic acid.
(3) Li-amide tse nang le mafura a mafura, li-ester tse kang vinyl bis-stearamide, butyl stearate, oleic acid amide, joalo-joalo E sebelisoa haholo-holo bakeng sa ho hasana, moo bis-stearamide e sebelisetsoang li-thermoplastics le li-plastiki tsa thermosetting, 'me e na le phello ea ho tlotsa. .
(4) Lisepa tsa tšepe tse kang stearic acid, zinc stearate, calcium stearate, pot stearate, magnesium stearate, lead stearate, joalo-joalo li na le phello ea ho tsitsisa mocheso le ho tlotsa.
(5) Lisebelisoa tse nang le karolo ea ho lokolloa ha hlobo, tse kang polydimethylsiloxane (methyl silicone oli), polymethylphenylsiloxane (phenylmethyl silicone oli), polydiethylsiloxane (ethyl silicone oli) joalo-joalo.
Ts'ebetsong ea ho bopa ente, ha ho sebelisoa 'mala o omileng, lisebelisoa tsa kalafo ea holim'a metsi joalo ka oli e tšoeu ea liminerale le oli ea phallo hangata li eketsoa nakong ea ho kopanya ho bapala karolo ea adsorption, lubrication, diffusion le tokollo ea hlobo.Ha ho etsoa mebala, lisebelisoa tse tala le tsona li lokela ho eketsoa ka tekanyo ea phepelo e mahareng.Pele u eketsa moemeli oa phekolo ea holim'a metsi 'me u hasane ka mokhoa o ts'oanang, ebe u eketsa toner' me u hasane ka mokhoa o ts'oanang.
Ha u khetha, ho hanyetsa mocheso oa dispersant ho lokela ho khethoa ho ea ka mocheso oa ho bōpa oa thepa e tala ea polasetiki.Ho ea ka pono ea litšenyehelo, ha e le hantle, dispersant e ka sebelisoang mocheso o bohareng le o tlaase ha ea lokela ho khethoa bakeng sa ho hanyetsa mocheso o phahameng.Mocheso o phahameng oa mocheso o hloka ho mamella mocheso ho feta 250 ℃.
