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)
