Masterbatch e ntšo ke eng?

Black masterbatch ke mofuta oa sesebelisoa sa ho taka mebala sa polasetiki, se entsoeng haholo-holo ka mebala kapa lintho tse kopantsoeng le resin ea thermoplastic, e qhibilihisitsoeng, e ntšitsoeng le e pelletized. E tsamaisana le resin ea motheo ts'ebetsong ea tlhahiso ea lihlahisoa tsa polasetiki 'me e li fa' mala o motšo. Sebopeho sa masterbatch e ntšo hangata se kenyelletsa pigment (mohlala, carbon black), resin ea carrier, dispersant le lintho tse ling tse eketsehileng. Pigment ke karolo ea bohlokoa ho khethoeng 'mala, resin ea carrier e thusa pigment ho hasana ka ho lekana sehlahisoa sa polasetiki, 'me dispersant le lintho tse ling tse eketsang li ntlafatsa ho hasana ha pigment le ts'ebetso ea ts'ebetso ea masterbatch.

Ts'ebetso ea tlhahiso ea masterbatch e ntšo e kenyelletsa mehato ea ho kopanya, ho kopanya, ho qhibilihisa, ho ntša, ho pholisa, ho kenya pelletising le ho paka. Khetho ea thepa e tala, ts'ebetso ea ho kopanya, ts'ebetso ea ho qhibiliha le ho ntša pelletising kaofela li na le tšusumetso ea bohlokoa ts'ebetsong ea ho qetela ea masterbatch e ntšo.

Libaka tsa ts'ebeliso ea li-masterbatches tse ntšo:

Black masterbatch e na le mefuta e mengata ea lits'ebetso, ho kenyeletsoa empa ho sa felle feela ho lisebelisoa tsa lapeng, likoloi, thepa ea ho paka, thepa ea kaho le tse ling. Indastering ea lisebelisoa tsa lapeng, black masterbatch e sebelisoa bakeng sa khetla le likarolo tsa ka hare tsa li-TV, mechini ea ho hlatsoa, ​​​​lihatsetsi, jj. Indastering ea likoloi, e sebelisoa bakeng sa tlhahiso ea likarolo tsa ka hare le tsa kantle tsa likoloi; indastering ea thepa ea ho paka, e sebelisoa bakeng sa tlhahiso ea mekotla e metšo ea polasetiki, mabokose, jj. Indastering ea thepa ea kaho, e sebelisoa bakeng sa tlhahiso ea lipeipi tse ntšo, liprofaele le tse ling.

Litšobotsi tsa ts'ebetso ea li-masterbatches tse ntšo li kenyelletsa ho qhalana hantle, matla a ho daea a phahameng, ts'ebetso e ntle ea ts'ebetso le thepa e tsitsitseng ea fisik'hemik'hale. Ts'ebetso ea ho qhalana e bohlokoa haholo bakeng sa masterbatch e ntšo, 'me ts'ebetso e mpe ea ho qhalana ha masterbatch e ntšo e tla ama lihlahisoa tsa polasetiki ka litsela tse ngata.

Litlamorao tsa ho hasana ho fokolang ha li-masterbatches tse ntšo ke life?

Taba ea pele, ho hasana ho sa lekanang ho tla lebisa bothateng ba phapang ea mebala kapa 'mala o sa lekanang oa sehlahisoa, e leng se tla ama boleng ba ponahalo ea sehlahisoa. Ea bobeli, li-masterbatches tse ntšo tse sa hasanngoang hantle li ka 'na tsa koala lisebelisoa nakong ea ts'ebetso, tsa eketsa litšenyehelo tsa tlhahiso le ho fokotsa bokhoni ba tlhahiso. Ho phaella moo, ho hasana ho fokolang ho ka boela ha lebisa ho fokotseha ha botsitso ba sehlahisoa, ho nosetsa habonolo kapa ho beha lintho ka har'a sona, ho ama bophelo ba tšebeletso ea sehlahisoa.

E le ho ntlafatsa ts'ebetso ea ho hasana ha masterbatch ea 'mala o motšo, mehato e latelang e ka nkuoa:

1. Ntlafatsa khetho ea thepa e tala ho netefatsa bohloeki le ho tšoana ha mebala ea boholo ba likaroloana le ho fokotsa litšila.

2. Fetola diparamente tsa tshebetso ya tlhahiso, tse kang ho eketsa mocheso wa ho kopanya le ho lelefatsa nako ya ho kopanya, e le ho kgothaletsa ho kopanya pigment le resin.

3. Sebelisa lisebelisoa tsa ho qhalanya tse sebetsang hantle haholo, joalo ka mochini o kopanyang oa Luo o nang le shear e phahameng, ho ntlafatsa ho qhala ha 'mala.

4. Khetha resine e loketseng ea ho jara ho netefatsa hore e lumellana hantle le resine e reretsoeng, e le ho nolofalletsa ho hasana ha 'mala.

5. Kenya tekanyo e loketseng ea sefafatsi ho fokotsa matla a tšebelisano lipakeng tsa likaroloana tsa pigment le ho khothaletsa ho hasana ha eona ka har'a resin.

Ka mekhoa ena, ts'ebetso ea ho qhalanya ha masterbatch e ntšo e ka ntlafatsoa ka katleho, e le ho ntlafatsa boleng ba lihlahisoa tsa polasetiki ka kakaretso.
