Kaboni wakuda woyera ndi chowonjezera choyera chosapanga dzimbiri chokhala ndi mphamvu zina zowonjezera, zomwe zimatha kulowa m'malo mwa kaboni wakuda kuti zilimbikitse zipangizo za rabara popanga zinthu za rabara, makamaka zinthu zoyera, zopepuka kapena zamitundu. Kugwiritsa ntchito kaboni wakuda woyera popanga matayala akunja kwa msewu, matayala aukadaulo, matayala a radial, ndi zina zotero kumathandizira kukonza magwiridwe antchito a matayala agalimoto ndikuwonjezera mtunda wa matayala. Ndiye kodi ntchito yeniyeni ya kaboni wakuda woyera m'matayala a rabara ndi iti, ndipo ndi chiyani chomwe chiyenera kusamalidwa mukamagwiritsa ntchito kaboni wakuda woyera popanga matayala?
1. Udindo wa kaboni woyera wakuda m'matayala
Kuwonjezera kaboni wakuda woyera pakupanga matayala kungachepetse kukana kwa matayala, kuchepetsa kugwiritsa ntchito mafuta, komanso kukulitsa kwambiri kukana kwa matayala komanso chitetezo. Kafukufuku wasonyeza kuti kusintha kaboni wakuda ndi kaboni wakuda woyera kungachepetse bwino mphamvu ya Paine ya zinthu za rabara, komanso kutayika kwa tan pa kutentha kwakukulu kwa δ, Potero kumawonjezera kukana kwa matayala. Kugwiritsa ntchito mankhwala onse oyera a kaboni wakuda kungachepetse kukana kwa matayala ndi 20% komanso kuchedwa kwa matayala ndi pafupifupi 50%, motero kusunga mafuta opitilira 3%.
Pambuyo powonjezera kaboni wakuda woyera pa fomula yonyamulira matayala, makhalidwe osiyanasiyana a tayala amakula kwambiri; Makamaka pakulimba kwa kukana kutopa kwa matayala, kugwedezeka konyowa, komanso kukana kugwedezeka.
2. Kugwiritsa ntchito kosayenera kwa kaboni wakuda woyera m'matayala
Pamene kaboni wakuda woyera umagwiritsidwa ntchito polimbitsa matayala a rabara, chifukwa cha malo ake ochepa olumikizirana, kugwirizana kwake ndi rabara kumakhala kofooka; Kusavuta kusonkhana, sikuthandiza kufalikira panthawi yosakaniza; Panthawi yogwiritsira ntchito vulcanization, pamakhala zotsatira zochedwa za vulcanization, zomwe zimatha kuyanjana mosavuta ndi zigawo zina. kaboni wakuda woyera umakonda kukumbatira zinthu zina zogwirizanitsa, zomwe sizingathandize kufalikira; Kusavuta kuuma madzi ndikupanga magulu a silicon oxide, zomwe sizingathandize kulumikiza; Kuuma kwa kapangidwe kake kumabweretsa kukhuthala kwakukulu panthawi yosungira. Chifukwa chake, opanga matayala ayenera kutenga njira zina kuti akonze momwe kaboni wakuda woyera amagwirira ntchito akamagwiritsa ntchito.
3. Njira zowongolera zotsatira za kuwonjezera kaboni woyera wakuda pamatayala
Pakupanga kwenikweni, kugwiritsa ntchito zosinthira kumatha kusintha mphamvu yowonjezera ya kaboni yoyera yakuda m'matayala, ndi zolumikizira ngati zazikulu, ndipo zolumikizira za silane zimagwiritsidwa ntchito kwambiri mu zolumikizira. Gulu la siloxy mu zolumikizira za silane limakhala ndi reactivity ndi zinthu zosapangidwa, pomwe gulu logwira ntchito la organic limakhala ndi reactivity kapena compatibility ndi zinthu zachilengedwe. Pamene cholumikizira cha silane chili pakati pa zolumikizira zosapangidwa ndi zachilengedwe ndi zachilengedwe, gawo lomangirira la organic matrix silane coupling agent inorganic matrix likhoza kupangidwa.
Kuwonjezera kuchuluka koyenera kwa silane coupling agent ku fomula ya tayala yolimbikitsidwa ndi silica kungapangitse mgwirizano wolimba pakati pa elastomer ndi mamolekyu a silica, kupititsa patsogolo kutalika kwa kukana kusweka ndi kung'ambika, ndikupangitsa kuti ntchito ya hysteresis ikhale yochepa.
Pakupanga kwenikweni, opanga matayala a rabara angagwiritsenso ntchito wakuda woyera wa kaboni wobalalitsidwa kwambiri. Wakuda woyera wa kaboni wobalalitsidwa kwambiri sungangotsimikizira bwino kuti matayala sakugwa bwino komanso kuti matayalawo sakugwa bwino, komanso umathandizira kuti zipangizo za rabara zisamawonongeke. Pakadali pano, njira zambiri zopangira matayala zimagwiritsa ntchito rabara yobwezerezedwanso. Ndili ndi mwayi wogawana nanu malangizo ogwiritsira ntchito wakuda woyera wa kaboni mu zipangizo za matayala zomwe zili ndi rabara yobwezerezedwanso.
