KraussMaffei inowedzerwa graphite dosing tekinoroji inobvumira izvo zvinhu kuti zvishandiswe sechinhu chinodzora moto, chinotsiva kana chinowedzera kumisanganiswa yemvura.
Zvinodiwa zvekupikiswa nemoto zve polyurethane foam zvikamu zviri kuwedzera pasi rose, muzvikamu zvemotokari nemaindasitiri, pamwe nekuda kwezvinodiwa zvekutonga. Kuti asangane nechido ichi, KraussMaffei (Munich, Germany) yakazivisa kuti ichaunza hurongwa hwakakwana hwekumanikidzwa kwepamusoro kweiyo inowedzera graphite kuti iwane yakakwirira zvinhu uye mashandiro ekuita, uye Cleaner Production show ichaitwa muDüsseldorf, Germany kubva Gumiguru 16 kusvika 2017 gore. 19th.
"Inowedzera graphite inodhura-inoshanda filler inopa mabhenefiti akajeka kune akawanda otomatiki application," anotsanangura Nicholas Bale, Mutungamiriri weReaction Equipment Division kuKraussMaffei. "Nehurombo, chinyorwa ichi chinonzwa kushushikana kwemagetsi panguva yekugadziriswa."
KraussMaffei's ichangobva kugadzirwa yakakwirira-kudzvanya kusanganisa musoro ine yakaderera-kudzvanya bypass uye yakakosha pre-mixing chiteshi chekuwedzera dosing graphite inoita kuti ive yakanyatsoshanda imwe nzira kana yekuwedzera kune yemvura zvinowedzera sechinhu chinodzora moto. Yakazara otomatiki macheni macheni anoderedza chikamu kutenderera nguva uye kuwedzera huwandu hwese system kunyatsoshanda.
KraussMaffei anoti mabhenefiti e-high-pressure countercurrent jekiseni musanganiswa weiyo chaiyo machining yeakanyanya reactive polyurethane foam masisitimu anogona kushandiswa mumashandisirwo apo inowedzerwa graphite inoshandiswa sekuzadza. Izvi zvinonzi zvinoumba hwaro hwekudzikisira nguva dzekutenderera uye kuwedzera kugona kwekugadzira. Muchiitiko ichi, kusiyana ne-low-pressure processing, musoro we-self-cleaning mixing head unonzi kubvisa kudiwa kwekutsvaira mushure mejojo rimwe nerimwe. KraussMaffei anoti izvi zvinochengetedza zvinhu uye nguva yekugadzira uye zvinobatsira kuchengetedza kunaka kwechigadzirwa, ukuwo kubvisa mutengo wekupa nekurasa zvinhu zvekutsvaira. Higher pressure mixing zvakare inowana yakakwirira kusanganisa simba. Izvi zvinogona kushandiswa kuderedza kutenderera nguva.
Iyi tekinoroji yakavakirwa pane yakakosha kuwedzera graphite kusanganisa misoro. Musoro mutsva wekusanganisa wakavakirwa paKraussMaffei yakakwirira-kumanikidza kusanganisa musoro. Iyo sisitimu ine yakaderera-kudzvanywa bypass yekuwedzera muchinjiko-chikamu uye yakagadzirirwa kugadzirisa inowedzera girafu. Nekuda kweizvozvo, iyo mechanic stress inoiswa pakuwedzera graphite zvimedu pakati pematenderedzwa anotevedzana matenderedzwa echaji polyol inodzikiswa. Nguva pfupi isati yatanga kudira, zvinhu zvinotenderera kuburikidza nemuromo, zvichigadzira kumanikidza. Naizvozvo, iyo filler iri pasi pekushomeka kwemagetsi kushushikana. Iine tekinoroji iyi, mazinga ekuzadza akakwira anogoneka, zvichienderana nezvinodiwa uye iyo mbishi system, inosvika kupfuura 30% nehuremu hwepolymer. Naizvozvo, inogona kusvika padanho repamusoro rekudzivirira moto UL94-V0.
Sekureva kwaKraussMaffei, musanganiswa wepolol uye kuwedzera graphite inogadzirirwa mune yakakosha pre-mixing station. Special blenders zvinosanganisa kuzadza nezvinwiwa zvemvura. Izvi zvinoitwa nenzira yakapfava, nokudaro kuchengetedza chimiro uye saizi yeanowedzera graphite particles. Dosing inogadzirwa uye huremu hwe polyol hunogona kuwedzerwa kusvika pa80%, kuve nechokwadi chekuenderana. Pamusoro pezvo, kugadzira kunova kwakachena uye kunoshanda zvakanyanya sekubata kwemaoko, kuyera uye kuzadza matanho kunobviswa.
Munguva ye premixing process, muyero wekusanganisa wekuwedzera graphite uye zvimwe zvikamu zvinogona kushandiswa kukwidziridza huremu uye huwandu hwezvikamu pasina kukanganisa moto retardant properties.
