Mokhoa oa ho rarolla mathata a tloaelehileng a ho sebetsana le mathata ali-masterbatches tsa mebala le li-masterbatches tsa ho tlatsa

'Mala ke e 'ngoe ea likarolo tse hlalosang ka ho fetisisa, karolo ea sebopeho e bonolo ka ho fetisisa e ka bakang thabo ea rona e tloaelehileng ea botle. Li-masterbatch tsa 'mala e le mokhoa oa ho sebelisa 'mala, li sebelisoa haholo lihlahisoa tse fapaneng tsa polasetiki tse amanang haufi-ufi le bophelo ba rona ba letsatsi le letsatsi, li eketsa mebala e mebala bophelong ba rona. Ho phaella moo, lihlahisoa tsa polasetiki, masterbatch ea ho tlatsa e boetse e bapala karolo ea bohlokoa ho fokotseng litšenyehelo tsa lihlahisoa, ho ntlafatsa katleho ea tlhahiso, ho ntlafatsa ho tiea ha lihlahisoa le likarolo tse ling li bapala karolo ea bohlokoa.

Lintlha tse Tloaelehileng tsa Bohloko ba Ts'ebetso eaLi-masterbatches tsa mebala le li-Masterbatches tsa ho tlatsa:

Masterbatch ea 'mala ke mofuta o mocha oa 'mala o khethehileng bakeng sa thepa ea polymer. E le ho etsa hore pigment e hasane ka ho lekana ka har'a masterbatch 'me e se ke ea hlola e hoama, ho eketsa ho hanyetsa boemo ba leholimo ba pigment, ho ntlafatsa ho hasana le matla a 'mala a pigment, hangata ho hlokahala ho eketsa dispersant ts'ebetsong.

Masterbatch ea Filler e entsoe ka resin e tsamaisang, filler le lintho tse ling tse eketsehileng. Ts'ebetsong ea tlhahiso ea filler masterbatch, e le ho ntlafatsa ho phalla ha ts'ebetso ea masterbatch le ho khothaletsa ho hasana ho ts'oanang ha masterbatch ka har'a resin ea matrix, li-dispersant le tsona lia sebelisoa.

Leha ho le jwalo, tshebetsong ya tlhahiso ya sebele, dispersants tse ngata di thata ho rarolla mathata a latelang, ka hona di baka hore ditjeo tsa tlhahiso ya di-color masterbatches le di-filler masterbatches di eketsehe:

1. Ho kopana ha phofo ea 'mala, ho kopana ha lintho tse tlatsang, ka hona ho ama lihlahisoa tsa polasetiki tsa ho qetela, tse kang lihlahisoa tsa mebala e fapaneng, ho thehoa ha likaroloana tse ngata tse tšoeu tse thata kapa "maru" lihlahisoa;

2. Ho bokellana ha thepa ka har'a hlobo ea molomo ka lebaka la ho hasana ho fokolang nakong ea tlhahiso ea li-masterbatches tsa mebala le li-masterbatches tsa ho tlatsa;

3. Ho se be le mmala o lekaneng le ho se potlake ha mmala ha di-masterbatches tsa mmala.

Phofo ea silicone ea SILIKE S201ke sesebelisoa sa ho sebetsana le phofo se nang le li-polysiloxane tse boima ba limolek'hule tse ngata haholo tse hasantsoeng ka silica, tse etselitsoeng ka ho khetheha li-masterbatches, li-polyolefin/filler masterbatches le li-masterbatches tse ling, tse ka ntlafatsang haholo thepa ea ts'ebetso, thepa ea bokaholimo le ho hasana ha li-filler tsamaisong ea polasetiki.Phofo ea silicone ea SILIKE S201e sebelisoa ho masterbatches le filler masterbatches ka melemo e latelang:

(1) E loketse mocheso o phahameng oa ts'ebetso ho feta boka ba PE, jj.;

(2) Ntlafatsa haholo tekanyo ea ho daea ea li-masterbatches tsa mebala;

(3) Ho fokotsa haholo monyetla oa ho bokellana ha li-filler le li-pigment;

(4) Fana ka tshebetso e betere ya ho qhalanya bakeng sa phofo ya filler le ya mmala, e le hore di ka qhalanngwa ka ho lekana ka hara resin ya carrier;

(5) Thepa e betere ea rheological (mokelikeli, khatello e tlase ea die le torque ea extrusion), e fokotsang ho thella ha screw le ho bokellana ha die;

(6) Ntlafatsa bokgoni ba tlhahiso le ho fokotsa ditjeo tsa tlhahiso;

(7) Fana ka botsitso bo botle ba mocheso le ho potlaka ha 'mala.

Ntle le li-masterbatches le li-filler masterbatches,Phofo ea silicone ea SILIKE S201e ka boela ea sebelisoa metsoakong ea terata le ea thapo, thepa ea PVC, polasetiki ea boenjiniere le masimo a mang a mangata. Ho eketsa hanyane ho ka ntlafatsa haholo ho phalla ha resin, ts'ebetso ea ho tlatsa hlobo, ho tlotsa ka hare le ts'ebetso ea ho lokolla hlobo le bokhoni ba tlhahiso, jj. Ha palo e ekelitsoeng e fihla ho 2%-5%, e ka ntlafatsa ho tlotsa, ea fana ka coefficient e tlase ea khohlano, le ho hanyetsa ka bokhabane ho feta ho mengoapo, tšenyo le ho khoptjoa.
