Kutanga, carbon black color
Kuwanda kwekupararira kwechiedza che "carbon black particles" kunodzikira nekudzikira kwesaizi, izvo zvinokanganisa kwete chete kupenya mhedzisiro asiwo toni. Heino chikonzero nei: Kana chiedza chikapfuura nepakati peruvara rune dema, pfupi-wavelength yebhuruu mwenje inopararira zvine simba kupfuura refu-wavelength dzvuku. Iyo yakanyanya kunaka kabhoni nhema, iyo inonyanya kukosha mhedzisiro. Nekuda kwekurasikirwa kudiki kwekuparadzira, chikamu dzvuku chinopinda muhupamhi hweruvara rwemavara, nepo kupararira kwese kwechiedza chebhuruu kusimba kupfuura kwechiedza chemaruva, uye zvakare yakasimba kune yakatarisana, iyo yekumashure kupararira, saka. inotaridzwa kubva kune coloring layer. Pakucherekedza maratidziro acho, ruvara rwebhuruu runoonekwa kana rwakapendwa nekabhoni dema, zvichipa fungidziro yehutema hukuru. Asi kana kabhoni dema iri hombe, inoenderana neruvara rwebrown, kana uchitarisa nzira yekutapurirana, iyo yakafanana coloring layer (isina kunyatsojeka firimu) tonal hukama pane zvinopesana, nekudzikira kwechikamu chekukura kugovera, kupararira kwakasimba kwechiedza chebhuruu kuburikidza. iyo coloring layer yakadzika idiki, mwenje webhuruu kuburikidza neruvara rwemavara kune rumwe rutivi chikamu ishoma, kupera kubva kune rimwe divi. Saka, nekuda kwekushaikwa kwechiedza chebhuruu padivi rakacherechedzwa, runyoro rweruvara runotora ruvara rwebrown kana ruchionekwa panguva yekufambisa. Kana madota (grey color) mukiyi yetitanium pigment, uye cherechedza iyo huru ruvara shading munzira yekutapurirana mamiriro akafanana neaya echiedza muzvidimbu zvepurasitiki zvewhite pigment pendi nhema inopararira nekudzoka, iyo idiki saizi ye. kabhoni dema, ita kuti ionekwe mukati meiyo yakasimba kupararira kwechiedza chebhuruu, saka pachave nekuwedzera dzvuku chikamu chekutapurirana kuuya pamusoro uye kupa neyero ruvara grey, pane zvinopesana, Kana iyo yakakora particle size. yekabhoni dema inoshandiswa pakuisa ruvara, kunyanya iro gobvu rambi dema, iyo grey ine yebhuruu toni ichawanikwa.Tamol NN
Vaviri, carbon black dispersion
Iyo pigment yakasviba, iyo yakawanda yekubatanidza nzvimbo pakati pekabhoni nhema aggregates, uye kusimba kwekubatana pakati pawo. Kana iyo pigment dema yakasanganiswa mukati mavo, iyo kabhoni dema inogovaniswa, iyo yakakura kupararira kwayo, iyo inogona kuparadzanisa kabhoni dema particles, kuitira kuti inosvika pakusviba kwepamusoro uye ruvara. Low structural kabhoni dema inowanzosvika pakakwirira pane yakakwira structural kabhoni dema, asi nekudaro inoda kupararira kukuru mukupararira. Kupararira kwekuita kwekabhoni dema kunokanganisa nehuwandu hwechimiro chayo. Yakakwira chimiro kabhoni dema ine yakanaka yekuparadzira kuita, saka simba rayo rekupenda rakasimba zvakasikwa. Asi mukushandiswa kwehupfu kabhoni dema, pachava nekupararira uye kunetseka matambudziko eguruva, saka, anogona kushandisa masterbatch kana slurry, saka mutengo we prefabricated kabhoni dema wakakwira pane nyore kushandisa pigment dema, asi kana uchifunga zvakanakira kuchena. maitiro, kushanda kwepamusoro, kushandiswa kwekabhoni dema kugadzirira kuchiri kudikanwa.Tamol NN
