Mpweya wakuda, ndi mpweya wa amorphous, wopepuka, wotayirira komanso wabwino kwambiri wakuda wakuda, womwe umamveka ngati pansi pa mphika.
Ndi chinthu chomwe chimapezedwa ndi kuyaka kosakwanira kapena kuwonongeka kwamafuta azinthu za carbonaceous monga malasha, gasi wachilengedwe, mafuta olemera, ndi mafuta amafuta pansi pa mpweya wosakwanira.
Chigawo chachikulu cha kaboni wakuda ndi kaboni, womwe ndi ma nanomaterial akale kwambiri omwe adapangidwa, kugwiritsidwa ntchito komanso kupangidwa ndi anthu. , yalembedwa ngati imodzi mwazinthu zoyambira makumi awiri ndi zisanu ndi mankhwala abwino opangidwa ndi makampani apadziko lonse lapansi.
Makampani opanga mpweya wakuda ndiwofunika kwambiri pamakampani opanga matayala, mafakitale opaka utoto komanso kukonza zinthu zabwino zamoyo wamba.
1. Malinga ndi kupanga
Makamaka ogawikana mu nyali wakuda, mpweya wakuda, ng'anjo wakuda ndi kagawo wakuda.
2. Molingana ndi cholinga
Malinga ndi ntchito zosiyanasiyana, kaboni wakuda nthawi zambiri amagawidwa kukhala wakuda wa kaboni kuti apange pigment, wakuda wakuda wa mphira, mpweya wakuda wakuda ndi wakuda wapadera wa carbon.
Mpweya wakuda wakuda wa pigment - Padziko lonse lapansi, malinga ndi mphamvu yopaka utoto wa kaboni wakuda, nthawi zambiri amagawidwa m'magulu atatu, omwe ndi amtundu wakuda wakuda wakuda, wakuda wamtundu wamtundu wamtundu wakuda ndi wakuda wakuda wakuda.
Gululi nthawi zambiri limayimiridwa ndi zilembo zitatu zachingerezi, zilembo ziwiri zoyambirira zikuwonetsa kuthekera kwa utoto wa kaboni wakuda, ndipo chilembo chomaliza chikuwonetsa njira yopangira.
3. Malinga ndi ntchito
Makamaka ogawanika kulimbitsa mpweya wakuda, wakuda mpweya wakuda, conductive mpweya wakuda, etc.
4. Malinga ndi chitsanzo
Amagawidwa kukhala N220,
Mpweya wakuda womwe umagwiritsidwa ntchito m'makampani opanga mphira umaposa 90% ya mpweya wakuda wakuda. Amagwiritsidwa ntchito makamaka pamitundu yosiyanasiyana ya matayala, monga matayala agalimoto, matayala a thirakitala, matayala a ndege, matayala agalimoto amphamvu, matayala a njinga, ndi zina zambiri. Pafupifupi ma kilogalamu 10 a kaboni wakuda amafunikira kupanga tayala wamba wamba.
Mu carbon wakuda wa rabara, oposa atatu mwa anayi a carbon black amagwiritsidwa ntchito popanga matayala, ndipo ena onse amagwiritsidwa ntchito muzinthu zina za labala, monga matepi, mapaipi, nsapato za rabara, ndi zina zotero. , kumwa kwa carbon black kumapangitsa pafupifupi 40-50% ya kumwa rabala.
Chifukwa chomwe mpweya wakuda umagwiritsidwa ntchito kwambiri mu rabala ndizomwe zimatchedwa "kulimbitsa" luso. Kukhoza "kulimbitsa" kumeneku kwa carbon black kunapezeka koyamba mu mphira wachilengedwe kumayambiriro kwa 1914. Tsopano zatsimikiziridwa kuti kwa mphira wopangidwa ndi mphira, mphamvu yolimbikitsira ya carbon black imagwira ntchito yofunika kwambiri.
Chizindikiro chofunikira kwambiri cha carbon black reinforcement ndikuwongolera magwiridwe antchito a matayala. Tayala lokhala ndi 30% yolimbitsa mpweya wakuda limatha kuyenda makilomita 48,000 mpaka 64,000; pamene akudzaza chodzaza chofanana cha inert kapena chosalimbitsa m'malo mwa carbon Black, mtunda wake ndi makilomita 4800 okha.
Kuphatikiza apo, kulimbitsa kaboni wakuda kumathanso kusintha mawonekedwe akuthupi ndi makina a zinthu za rabara, monga kulimba kwamphamvu komanso kung'ambika. Mwachitsanzo, kuwonjezera mphira wakuda wakuda ku mphira wonyezimira monga mphira wachilengedwe kapena neoprene kumatha kukulitsa mphamvu zolimba pafupifupi 1 mpaka 1.7 poyerekeza ndi mphira woyaka wopanda mpweya wakuda; Mu rabara, imatha kukulitsidwa mpaka 4 mpaka 12.
Mumakampani opanga mphira, mtundu wa kaboni wakuda ndi kuchuluka kwake kophatikizana uyenera kutsimikiziridwa molingana ndi cholinga ndi momwe amagwiritsidwira ntchito. Mwachitsanzo, pakuponderezedwa kwa matayala, kukana kuvala kuyenera kuganiziridwa poyamba, kotero kuti ng'anjo yakuda yolimba kwambiri, monga ng'anjo yakuda yakuda, ng'anjo yapakatikati yolimbana ndi ng'anjo yakuda kapena ng'anjo yakuda yakuda kwambiri. ; pamene kuponda ndi mphira nyama Zinthu zimafuna mpweya wakuda ndi osachepera hysteresis kutaya ndi kutsika kutentha m'badwo.
