Zombini i-dispersants kunye ne-lubricant zidla ngokusetyenziswa izongezo zokudibanisa umbala weplastiki.Ukuba ezi zongezo zongezwa kwizinto eziluhlaza zemveliso, kufuneka zongezwe kwi-resin ekrwada kwi-protection efanayo kwi-coloring proofing proofing, ukwenzela ukuba ugweme ukuhluka kombala kwimveliso elandelayo.
Iindidi ze-dispersants zezi: i-fatty acid polyureas, i-base stearate, i-polyurethane, isepha ye-oligomeric, njl njl. Ii-dispersants ezisetyenziswa ngokuqhelekileyo kwishishini zizithambiso.I-Lubricants ineempawu ezilungileyo zokusasazwa, kwaye inokuphucula ubumanzi kunye neempawu zokukhupha iiplastiki ngexesha lokubumba.
Izithambiso zohlulwe zibe zizithambiso zangaphakathi kunye nezithambisi zangaphandle.Izithambisi zangaphakathi zinokuhambelana okuthile kunye ne-resin, ezinokunciphisa ukudibanisa phakathi kwamaketanga e-resin molecular, ukunciphisa i-viscosity enyibilikayo, kunye nokuphucula i-fluidity.Ukuhambelana phakathi kwe-lubricant yangaphandle kunye ne-resin, ibambelela kumphezulu we-resin etyhidiweyo ukwenza i-lubricating molecular molecular, ngaloo ndlela inciphisa ukungqubana phakathi kwe-resin kunye nezixhobo zokucubungula.Izithambisi zohlulwe ikakhulu kwezi ndidi zilandelayo ngokokwakheka kweekhemikhali zazo:
(1)) Iklasi yokutshisa njengeparafini, i-polyethylene wax, i-polypropylene wax, i-micronized wax, njl.
(2) Ii-acids ezinamafutha ezifana ne-stearic acid kunye ne-base stearic acid.
3 .
(4) Iisepha zesinyithi ezifana ne-stearic acid, i-zinc stearate, i-calcium stearate, i-pot stearate, i-magnesium stearate, i-lead stearate, njl.
(5) I-Lubricants edlala indima ekukhululweni kwesikhunta, njenge-polydimethylsiloxane (i-methyl silicone ioli), i-polymethylphenylsiloxane (i-phenylmethyl ioli ye-silicone), i-polydiethylsiloxane (i-ethyl silicone ioli) njl.
Kwinkqubo yokubumba isitofu, xa kusetyenziswa umbala owomileyo, ii-arhente zonyango zomphezulu ezifana neoyile yeminerali emhlophe kunye neoyile yokusasazwa iyongezwa ngokubanzi ngexesha lokuxuba ukudlala indima ye-adsorption, i-lubrication, i-diffusion kunye nokukhululwa kokungunda.Xa ufaka umbala, izinto eziluhlaza kufuneka zongezwe kwi-proportion medium deployment.Okokuqala yongeza i-agent yonyango yomhlaba kwaye usasaze ngokulinganayo, uze udibanise i-toner kwaye usasaze ngokulinganayo.
Xa ukhetha, ukuchasana kweqondo lokushisa kwe-dispersant kufuneka kunqunywe ngokuhambelana nokushisa okubunjwa kwezinto eziluhlaza zeplastiki.Ukususela kumbono weendleko, ngokomgaqo, i-dispersant engasetyenziselwa kwiqondo lokushisa eliphakathi kunye neliphantsi akufanele likhethwe ukuchasana nokushisa okuphezulu.Isixhobo sokuchitha ubushushu obuphezulu kufuneka sixhathise ukuya kuma 250℃.
