Okokuqala, umbala omnyama wekhabhoni
Iqondo lokusasazeka kokukhanya kwe "carbon black particles" iyancipha ngokuhla kwesayizi yesuntswana, echaphazela kungekuphela nje umphumo oqaqambileyo kodwa kunye nethoni. Nasi isizathu: Xa ukukhanya kudlula umaleko wombala olawulwa bubumnyama, ubude obufutshane bobude obuluhlaza ukukhanya busasazeke ngamandla kunobude obubomvu bokukhanya. Okukhona ikhabhoni emnyama icolekileyo, kokukhona isiphumo sibaluleke ngakumbi. Ngenxa yelahleko encinci yokusasazeka, icandelo elibomvu lingena kubunzulu bomaleko wombala, ngelixa ukusasazeka ngokubanzi kokukhanya okuluhlaza okwesibhakabhaka kunamandla kunokukhanya kwentyatyambo, kwaye yomelele kwelinye icala, oko kukuthi, ukusasazeka ngasemva, ibonakaliswa kuluhlu lombala. Xa uqwalasela inkqubo yokubonakalisa, i-blue hue ibonakala xa ifakwe umbala wekhabhoni ecolekileyo, inika ingcamango yobumnyama obukhulu. Kodwa ukuba i-carbon emnyama inkulu, ngokuhambelanayo ibonisa umbala omdaka, xa uqwalasela inkqubo yokudluliselwa, umbala ofanayo wombala (ongekho ifilimu ecacileyo ngokupheleleyo) ubudlelwane be-tonal ngokuchaseneyo, kunye nokuncipha kokusabalalisa ubungakanani bamasuntswana, ukusasazeka okunamandla kokukhanya okuluhlaza okwesibhakabhaka. ubunzulu bomaleko wombala buncinci, ukukhanya okuluhlaza okwesibhakabhaka ngokusebenzisa umaleko wombala ukuya kwelinye icala kuncinci, kugugile ukusuka kwelinye icala. Ngaloo ndlela, ngenxa yokungabikho kokukhanya okuluhlaza okwesibhakabhaka kwicala eliqwalaselweyo, umaleko onemibala uthatha i-brown hue xa ujongwa ngexesha lokudluliselwa. Xa umlotha (umbala ongwevu) kwisitshixo se-titanium pigment, kwaye ujonge umbala ophambili wokufihlwa kwinkqubo yosulelo olufana nolo lokukhanya kwiziqwenga zeplastiki yepeyinti emhlophe yepeyinti esasaza emva naphambili, kokukhona ubungakanani besuntswana elincinci Ikhabhoni emnyama, yenza kubonakale ngaphakathi ngamandla ukusasazeka kokukhanya okuluhlaza okwesibhakabhaka, ngoko kuya kubakho inxalenye ebomvu yosasazo oluza ngaphaya kwaye lubonise ngombala otyheli ongwevu, ngokuchaseneyo, ukuba ubungakanani besuntswana elirhabaxa. Ikhabhoni emnyama isetyenziswa xa kufakwa umbala, ngakumbi isibane esityebileyo esimnyama, ingwevu enethoni eluhlaza okwesibhakabhaka iya kufumaneka.Tamol NN
Isibini, ukusasazwa kwekhabhoni emnyama
Okukhona i-pigment emnyama icolekileyo, kokukhona kuqhagamshelwana ngakumbi phakathi kwe-carbon black aggregates, kwaye komelele ukuhlangana phakathi kwazo. Xa i-pigment emnyama ixutywe kubo, i-carbon black isasazwa ngokulinganayo, ukusasazeka kwayo okukhulu, okunokwahlula i-carbon black particles, ukwenzela ukuba ekugqibeleni ifikelele kubumnyama obuphezulu kunye nombala. Ulwakhiwo oluphantsi lwekhabhoni emnyama kunokwenzeka ukuba lufikelele kugxininiso oluphezulu kunolwakhiwo oluphezulu lwekhabhoni emnyama, kodwa ke lufuna ukusasazwa okukhulu kwinkqubo yokusasazwa. Ukusebenza kwe-dispersion of carbon black kuchaphazeleka ngumgangatho wesakhiwo sayo. Isakhiwo esiphakamileyo sekhabhoni emnyama inomsebenzi olungileyo wokusasazeka, ke amandla ayo ombala anamandla ngokwendalo. Kodwa ekusebenziseni i-carbon powder emnyama, kuya kubakho iingxaki kunye neengxaki zothuli, ngoko ke, unokusebenzisa i-masterbatch okanye i-slurry, ngoko ke ixabiso lekhabhoni elimnyama elifakwe ngaphambili liphezulu kunokusebenzisa okulula kwe-pigment emnyama, kodwa ukuba kuqwalaselwa iingenelo zokucoca. inkqubo, ukusebenza kakuhle, ukusetyenziswa kokulungiswa kwekhabhoni emnyama kusafuneka kakhulu.Tamol NN
