TonernameJapanese:トナー

Tarkoitus

Väriaineita käytetään pääasiassa lasertulostimissa tulostuskoneissa.

Tuotantomenetelmä

Vastauksena erilaisiin tarpeisiin, väriaineen tuotanto kehittyy jalostuksen, värityksen ja suuren nopeuden suuntaan. Väriaineen tuotanto omaksuu pääasiassa pulverointi- ja polymerointimenetelmiä:

Polymerointimenetelmä

Polymerointimenetelmä, joka poistaa kemiallisen hiilijauheteknologian, joka sisältää (suspensiopolymeroinnin, emulsiopolymeroinnin ja mikrokapselin, dispersiopolymeroinnin, puristuspolymeroinnin, kemiallisen jauheen).

Polymerizedtonertechnologyhasexistedformanyyears:

—Ensimmäinen patentti polymeroidulle sävylle ilmestyi vuonna 1972.

—1970- ja 1980-luvulla sitä parannettiin laajalti.

—Ensimmäinen kaupallinen yksivärinen sävy ilmestyi vuonna 1993.

—Ensimmäinen kaupallinen värisävy ilmestyi vuonna 1998.

Polymeroidun hiilijauheen tekninen prosessi:

(hartsimonomeeri, pigmentti, dispergointiaine, muut reagenssit)→(ultraäänidispersio)→(vesi, dispergointiaine)→(täysi sekoittaminen)→(polymerointi)→(pesu)→(suodatus ja erotus)→(kuivaus)→(jälkikäsittely)→( Valmis tuote)
