Ndili mwana, nthawi zonse ndimamva akuluakulu akunena kuti, osaluma pensulo, apo ayi udzakhala ndi poizoni ndi mtovu! Koma kwenikweni, chigawo chachikulu cha pensulo chotsogolera ndi graphite, osati lead, ndipo sitidzakhala poizoni mwa kulumidwanso kawiri.
Pali "mayina" ambiri m'moyo omwe samagwirizana ndi mayina "enieni", monga mapensulo alibe mtovu, Nyanja Yakufa si nyanja ... Kuweruza kamangidwe ka chinthu ndi dzina lokha sikungagwire ntchito. Ndiye funso ndilakuti, kodi tona ya chosindikizirayo idangopangidwa ndi "inki"? Tiyeni tiwone momwe toner imawonekera!
Ku China, magwero a inki ndi oyambirira kwambiri, ndipo pali zolemba za inki pamafupa amtundu wa Shang Dynasty, ndipo inkiyo yayesedwa ndi akatswiri ngati mpweya wakuda. Choncho inki yaku China imatchedwanso inki ya carbon, ndipo tona imatchedwanso tona. Kodi chosindikizira cha tona chapangidwa ndi "inki"? Ndipotu, zikutanthauza kuti sichipangidwa ndi "carbon".
Kuyang'anitsitsa mndandanda wazinthu zake mudzapeza kuti ili ndi resins, carbon black, charge agents, zowonjezera zakunja, ndi zina zotero, zomwe kaboni wakuda umakhala ngati thupi lopaka utoto, umakhala ngati utoto, ndipo uli ndi ntchito yosintha kuya kwa mtundu. . Kunena zowona, utomoni ndiye chinthu chachikulu chojambula cha tona ndipo ndiye chigawo chachikulu cha tona.
M'moyo weniweni, njira zopangira tona zimagawidwa m'mitundu iwiri: njira yopera yakuthupi ndi njira yopangira ma polymerization.
Pakati pawo, makampani opanga ma tona amagwiritsa ntchito njira zambiri zophwanyira, zomwe zimatha kupanga ma tona oyenera kukopera kowuma kowuma: kuphatikiza tona yamagulu awiri ndi tona imodzi (kuphatikiza maginito ndi maginito). Njirayi imafuna kusakaniza kolimba kwa ma resin olimba, zida za maginito, inki, zowongolera zowongolera, phula, ndi zina zotere, kutenthetsa kusungunula utomoni, ndipo nthawi yomweyo kufalitsa zinthu zosasungunuka mu utomoni. Pambuyo pozizira ndi kulimba, zimaphwanyidwa ndikugawidwa.
Ndi chitukuko cha osindikiza, zofunikira za tona zikuchulukirachulukira, ndipo kupanga kwa tona kumakonzedwanso. Chemical polymerization njira ndi luso tona bwino, kuyambira 1972, mlandu woyamba wa polymerization tona wapadera li anaonekera mpaka pano, luso wakhala kwambiri okhwima.
Ikhoza kupanga tona ndi kutentha kochepa kosungunuka, komwe kungakwaniritse zofunikira zamakono zamakono zopulumutsa mphamvu ndi kuteteza chilengedwe. Ndi kusintha mlingo wa dispersant, oyambitsa liwiro, polymerization nthawi ndi ndende ya yankho, tinthu kukula kwa tona particles amalamulidwa kukwaniritsa zotsatira yunifolomu zikuchokera, mtundu wabwino ndi mkulu kuwonekera. The tona opangidwa ndi polymerization njira ali wabwino tinthu mawonekedwe, ndi bwino tinthu kukula, yopapatiza tinthu kukula kugawa ndi fluidity wabwino. Ikhoza kukwaniritsa zofunikira zamakono zamakono zosindikizira monga kuthamanga kwambiri, kusamvana kwakukulu ndi mtundu.
