Ukadaulo wowonjezera wa graphite wa KraussMaffei umalola kuti zinthuzo zigwiritsidwe ntchito ngati choletsa moto, choloweza m'malo kapena chowonjezera ku zosakaniza zamadzimadzi.
Zofunikira pakukana moto kwa magawo a thovu la polyurethane zikuchulukirachulukira padziko lonse lapansi, m'magalimoto ndi mafakitale, komanso chifukwa cha malamulo. Kuti akwaniritse izi, KraussMaffei (Munich, Germany) adalengeza kuti ipereka njira yokwanira yopangira ma graphite owonjezera kuti akwaniritse zinthu zambiri komanso magwiridwe antchito, ndipo chiwonetsero cha Cleaner Production chidzachitika ku Düsseldorf, Germany kuyambira Okutobala 16 mpaka Okutobala 16. 2017 chaka. 19 ndi.
Nicholas Bale, Purezidenti wa Reaction Equipment Division ku KraussMaffei anati: "Tsoka ilo, nkhaniyi imakhudzidwa ndi kupsinjika kwamakina panthawi yokonza."
Mutu wa KraussMaffei womwe wangopangidwa kumene kwambiri wokhala ndi mphamvu yocheperako komanso malo apadera osakanikirana kuti awonjezere graphite kumapangitsa kuti ikhale njira yothandiza kwambiri kapena yowonjezera pazowonjezera zamadzimadzi ngati choletsa moto. Unyolo wokhazikika wokhawokha umachepetsa nthawi zozungulira ndikuwonjezera magwiridwe antchito onse.
KraussMaffei akunena kuti phindu la kusakanikirana kwa jekeseni wotsutsana ndi kuthamanga kwapamwamba kwa makina olondola kwambiri a machitidwe a thovu a polyurethane amatha kugwiritsidwa ntchito pamene graphite yowonjezera imagwiritsidwa ntchito ngati chodzaza. Izi zimanenedwa kuti ndizo maziko ochepetsera nthawi yozungulira ndikuwonjezera luso la kupanga. Mwanjira iyi, mosiyana ndi kutsika kwapang'onopang'ono, mutu wodzitchinjiriza wodzitchinjiriza umati kumachotsa kufunikira kwa kuthamangitsidwa pambuyo pa jekeseni iliyonse. KraussMaffei akuti izi zimapulumutsa zida ndi nthawi yopangira komanso zimathandiza kuti zinthu ziziyenda bwino, ndikuchotsanso mtengo wopereka ndi kutaya zinthu zotayira. Kuphatikizika kwamphamvu kwambiri kumapangitsanso mphamvu zosakanikirana. Izi zitha kugwiritsidwa ntchito kuchepetsa nthawi yozungulira.
Ukadaulowu umachokera pamitu yapadera yosakanikirana ndi ma graphite. Mutu watsopano wosakaniza umachokera ku mutu wa KraussMaffei wothamanga kwambiri. Dongosololi lili ndi njira yocheperako yocheperako yowonjezereka ndipo idapangidwa kuti ikonzekere graphite yowonjezereka. Chifukwa chake, kupsinjika kwamakina komwe kumachitika pakukula kwa tinthu tating'ono ta graphite pakati pa mizere yotsatizana ya polyol yoyipitsidwa kumachepetsedwa. Kutangotsala pang'ono kuthira kumayamba, zinthuzo zimazungulira kudzera mumphuno, ndikupanga kupanikizika. Chifukwa chake, chodzazacho chimakhala ndi zovuta zochepa zamakina. Ndi ukadaulo uwu, milingo yodzaza kwambiri ndizotheka, kutengera zofunikira ndi zida zopangira, mpaka 30% polemera polima. Chifukwa chake, imatha kufika pamlingo wapamwamba kwambiri wokana moto UL94-V0.
Malinga ndi KraussMaffei, chisakanizo cha polyol ndi kukula kwa graphite kumakonzedwa pamalo apadera osakanikirana. Osakaniza apadera amasakaniza kudzazidwa ndi zosakaniza zamadzimadzi. Izi zimachitika modekha, motero kusunga dongosolo ndi kukula kwa expandable graphite particles. Kuyeza kumangochitika zokha ndipo kulemera kwa polyol kumatha kuonjezedwa mpaka 80%, kuwonetsetsa kuti zinthu sizisintha. Kuonjezera apo, kupanga kumakhala koyera komanso kothandiza kwambiri monga momwe kugwiritsira ntchito pamanja, kuyeza ndi kudzaza njira kumathetsedwa.
Pa ndondomeko premixing, ndi kusanganikirana chiŵerengero cha kukulitsa graphite ndi zigawo zina angagwiritsidwe ntchito kukhathamiritsa kulemera ndi buku la zigawo zikuluzikulu popanda kuphwanya moto retardant katundu.
