Ngisemncane ngangihlale ngizwa abantu abadala bethi, ungalumi ipeni, kungenjalo uzodliswa umthofu! Kodwa empeleni, ingxenye eyinhloko yomthofu wepensela i-graphite, hhayi umthofu, futhi ngeke sifakwe ubuthi ngokuthatha ezinye izibiliboco ezimbili.
Maningi "amagama" empilweni angahambisani namagama "angempela", njengamapensela awanawo umthofu, uLwandle Olufile alulona ulwandle... Ukwahlulela ukwakheka kwento ngegama lodwa ngeke kusebenze. Ngakho umbuzo uwukuthi, ingabe i-toner yephrinta imane yenziwe "ngoyinki"? Ake sibheke ukuthi i-toner ibukeka kanjani!
E-China, umsuka we-inki usaqala kakhulu, futhi kukhona ukubhalwa kwe-inki emathanjeni e-oracle Obukhosi baseShang, futhi uyinki uhlolwe ngochwepheshe njengekhabhoni emnyama. Ngakho uyinki waseShayina ubizwa nangokuthi uyinki we-carbon, futhi i-toner ibizwa nangokuthi i-toner. Ingabe i-toner yephrinta yenziwe "ngoyinki"? Eqinisweni, kusho ukuthi akwenziwa "ngekhabhoni".
Ukubhekisisa uhlu lwesithako sayo kuzothola ukuthi inama-resin, i-carbon black, ama-charge agents, izithasiselo zangaphandle, njll., lapho i-carbon black isebenza njengomzimba wombala, isebenza njengodayi, futhi inomsebenzi wokulungisa ukujula kombala. . Ukukhuluma ngokuqinile, i-resin iyinto eyinhloko yokucabanga ye-toner futhi iyingxenye eyinhloko ye-toner.
Empilweni yangempela, izindlela zokukhiqiza ze-toner zihlukaniswe izinhlobo ezimbili: indlela yokugaya ngokomzimba kanye nendlela ye-polymerization yamakhemikhali.
Phakathi kwazo, imboni yokucubungula i-toner isebenzisa inani elikhulu lezindlela zokuchoboza, ezingakhiqiza amathoni afanele ukukopisha okomile kwe-electrostatic: kufaka phakathi i-toner enezingxenye ezimbili kanye ne-toner eyodwa (kuhlanganise namagnetic kanye ne-non-magnetic). Le ndlela idinga ingxube enzima yama-resin aqinile, izinto zikazibuthe, izingulube, ama-ejenti okulawula ukushaja, ama-wax, njll., ukushisa ukuze kuncibilike inhlaka, futhi ngesikhathi esifanayo kuhlakazeke ngokulinganayo izingxenye ezingancibiliki ku-resin. Ngemuva kokupholisa nokuqiniswa, iyachotshozwa futhi ihlukaniswe.
Ngokuthuthukiswa kwamaphrinta, izidingo ze-toner ziya ngokuya ziba phezulu, futhi ukukhiqizwa kwe-toner kucwengwa kakhulu. Indlela ye-Chemical polymerization iwubuchwepheshe obuhle be-toner, ekuqaleni kuka-1972, icala lokuqala le-polymerization toner li elikhethekile labonakala kuze kube manje, ubuchwepheshe buye bavuthwa kakhulu.
Ingakwazi ukwenza i-toner enezinga lokushisa eliphansi elincibilikayo, elingahlangabezana nezidingo zobuchwepheshe besimanje okonga amandla nokuvikela imvelo. Ngokulungisa umthamo we-dispersant, isivinini esishukumisayo, isikhathi se-polymerization kanye nokuhlushwa kwesisombululo, usayizi wezinhlayiyana zezinhlayiya ze-toner zilawulwa ukuze kuzuzwe umphumela wokubunjwa okufanayo, umbala omuhle nokubonakala okuphezulu. I-toner ekhiqizwa indlela ye-polymerization inomumo omuhle wezinhlayiyana, usayizi wezinhlayiyana ocolekile, ukusabalalisa usayizi wezinhlayiyana ezincane kanye noketshezi oluhle. Ingakwazi ukuhlangabezana nezidingo zobuchwepheshe bokuphrinta besimanje njengejubane eliphezulu, ukulungiswa okuphezulu nombala.
