Khabone e ntšo ke eng?

Carbon black, ke phofo ea amorphous carbon, e khanyang, e hlephileng le e ntle ka ho fetisisa e ntšo, e ka utloisisoang e le tlase ea pitsa.

Ke sehlahisoa se fumanoang ka ho chesa ho sa phetheheng kapa ho senyeha ha mocheso oa lintho tse nang le carbonaceous tse kang mashala, khase ea tlhaho, oli e boima, le oli ea mafura tlas'a boemo ba moea o sa lekaneng.


Carbon Black


Karolo e ka sehloohong ea carbon black ke carbon, e leng li-nanomaterial tsa pele tse entsoeng, tse sebelisoang le tse hlahisoang ke moloko oa batho hona joale. , e thathamisitsoe e le e 'ngoe ea lihlahisoa tsa motheo tsa lik'hemik'hale tse mashome a mabeli a metso e mehlano le lihlahisoa tse ntle tsa lik'hemik'hale ke indasteri ea machaba ea lik'hemik'hale.

Indasteri ea khabone e ntšo e bohlokoa haholo indastering ea lithaere, indastering ea ho daea le ho ntlafatsa boleng ba lihlahisoa tsa bophelo ba sechaba.



Ea bobeli, ho aroloa ha carbon black

1. Ho ea ka tlhahiso

Haholo-holo e arotsoe ka lebone le letšo, khase e ntšo, sebōpi se ntšo le sekoti se letšo.


2. Ho ea ka morero

Ho ea ka litšebeliso tse fapaneng, hangata carbon black e arotsoe ka carbon black bakeng sa pigment, carbon black bakeng sa rabara, conductive carbon black le carbon black e khethehileng.


Khabone e ntšo bakeng sa pigment - Linaheng tsa machaba, ho ea ka bokhoni ba 'mala oa carbon black, hangata e arotsoe ka lihlopha tse tharo, e leng carbon black-pigment, medium-pigment carbon black and low pigment carbon black.

Sehlopha sena se atisa ho emeloa ke litlhaku tse tharo tsa Senyesemane, litlhaku tse peli tsa pele li bontša bokhoni ba mebala ea carbon black, 'me lengolo la ho qetela le bontša mokhoa oa tlhahiso.


3. Ho ea ka mosebetsi

Haholo-holo e arotsoe ka carbon black e matlafalitsoeng, carbon black black, conductive carbon black, joalo-joalo.


4. Ho latela mohlala

E arotsoe haholo ka N220,


Kopo indastering ea rabara

Khabone e ntšo e sebelisoang indastering ea rabara e etsa karolo e fetang 90% ea kakaretso ea khabone e ntšo. Haholo-holo e sebelisoa bakeng sa mefuta e fapaneng ea lithaere, joalo ka lithaere tsa koloi, lithaere tsa terekere, lithaere tsa sefofane, lithaere tsa koloi ea motlakase, lithaere tsa libaesekele, joalo-joalo. Ho hlokahala lik'hilograma tse 10 tsa carbon black ho etsa thaere e tloaelehileng ea koloi.


Ka har'a carbon black bakeng sa rabara, ho feta kotara tse tharo tsa carbon black e sebelisoa ha ho etsoa lithaere, 'me e setseng e sebelisoa lihlahisoa tse ling tsa rabara, tse kang litheipi, li-hose, lieta tsa rabara, joalo-joalo. , tšebeliso ea carbon black account bakeng sa hoo e ka bang 40 ~ 50% ea tšebeliso ea rabara.


Lebaka leo ka lona carbon black e sebelisoang haholo ka rabara ke bokhoni ba eona bo babatsehang boo ho thoeng ke "ho matlafatsa". Bokhoni bona ba "ho matlafatsa" ba carbon black bo ile ba fumanoa ka lekhetlo la pele ka rabara ea tlhaho ho tloha ka 1914. Hona joale ho netefalitsoe hore bakeng sa rabara ea maiketsetso, matla a ho matlafatsa carbon black a phetha karolo ea bohlokoa le ho feta.


Letšoao la bohlokoa ka ho fetisisa la ho matlafatsa carbon black ke ho ntlafatsa ts'ebetso ea ho roala ha thaere. Taere e matlafalitsoeng ka 30% ea carbon black e ka tsamaea lik'hilomithara tse 48,000 ho isa ho 64,000; ha e ntse e tlatsa palo e lekanang ea setlolo sa inert kapa se sa matlafatsang sebakeng sa carbon Black, sebaka sa eona sa lik'hilomithara ke lik'hilomithara tse 4800 feela.


Ho feta moo, carbon black e matlafalitsoeng e ka boela ea ntlafatsa thepa ea 'mele le ea mechine ea lihlahisoa tsa rabara, tse kang matla a tsitsitseng le matla a ho taboha. Ka mohlala, ho eketsa matla a carbon black ho rabara ea kristale e kang rabara ea tlhaho kapa neoprene ho ka eketsa matla a ho tiea ka makhetlo a ka bang 1 ho isa ho 1.7 ha ho bapisoa le rabara e chesitsoeng ntle le carbon black; Ka rabara, e ka eketsoa ka makhetlo a ka bang 4 ho isa ho a 12.


Ka indasteri ea rabara, mofuta oa carbon black le palo ea eona e kopantsoeng e lokela ho khethoa ho latela morero le maemo a tšebeliso ea sehlahisoa. Mohlala, bakeng sa lithaere tsa thaere, ho tlameha ho nahanoa pele ka ho hanyetsa ho roala, kahoo ho hlokahala hore ho be le mabone a matla a matla a carbon a kang a ultra-abrasion-resistant, sebopi se sefubelu se phahameng se sa keneleng mocheso kapa sebōpi se sa thibeleng ho chesa haholo. ; ha a ntse a hatakela le rabara ea setopo Thepa e hloka carbon black e nang le tahlehelo e fokolang ea hysteresis le tlhahiso e tlaase ea mocheso.
