Teknụzụ dosing KraussMaffei na-agbasa graphite na-enye ohere iji ihe ahụ dị ka ihe na-egbochi ọkụ, nnọchi ma ọ bụ mgbakwunye na ngwakọta mmiri mmiri.
Ihe ndị a chọrọ maka ọkụ ọkụ nke akụkụ ụfụfụ polyurethane na-abawanye n'ụwa nile, ma n'ime ụgbọ ala na ụlọ ọrụ mmepụta ihe, yana n'ihi usoro iwu chọrọ. Iji mezuo ọchịchọ a, KraussMaffei (Munich, Germany) kwupụtara na ọ ga-eweta usoro zuru ezu maka nhazi nrụgide dị elu nke graphite na-agbasawanye iji nweta ihe dị elu na nhazi usoro, na ihe ngosi Cleaner Production ga-enwe na Düsseldorf, Germany site na October 16 ruo October 16. 2017 afọ. 19th.
"graphite na-agbasawanye bụ ihe nchacha dị ọnụ ahịa nke na-enye uru doro anya maka ọtụtụ ngwa akpaaka," Nicholas Bale na-akọwa, Onye isi oche nke Reaction Equipment Division na KraussMaffei. "N'ụzọ dị mwute, ihe a na-enwe mmetụta maka nrụgide ọrụ n'oge nhazi."
KraussMaffei ọhụrụ emepụtara elu-nrụgide isi na-agwakọta isi na obere nrụgide ụzọ na ebe pụrụ iche tupu mixing maka dosing ịgbasa graphite na-eme ka ọ bụrụ ihe dị irè karịsịa ọzọ ma ọ bụ ihe mgbakwunye na mmiri mmiri mgbakwunye dị ka ọkụ retardant. Agbụ usoro akpaaka zuru oke na-ebelata oge okirikiri akụrụngwa ma na-abawanye arụmọrụ sistemu niile.
KraussMaffei na-ekwu na uru nke nnukwu nrụgide countercurrent injection ịgbakọ maka nkenke machining nke ukwuu polyurethane foam usoro nwere ike na-erigbu na ngwa ebe expandable graphite na-eji dị ka ihe ndochi. Nke a na-akọ na-etolite ntọala maka ibelata oge okirikiri yana ịbawanye arụmọrụ mmepụta. N'ime usoro a, n'adịghị ka nhazi nke nrụgide dị ala, a na-ekwu na isi nchịkọta na-ehicha onwe ya na-ewepụ mkpa ọ dị maka ịmịnye mmiri mgbe ọ bụla ntụtụ. KraussMaffei na-ekwu na nke a na-azọpụta ihe na oge mmepụta ma na-enyere aka ịnọgide na-enwe àgwà ngwaahịa na-agbanwe agbanwe, ma na-ewepụkwa ọnụ ahịa nke inye na ikpofu ihe ndị na-asọ oyi. Ịgwakọta nrụgide dị elu na-enwetakwa ike ịgwakọta ike dị elu. Enwere ike iji nke a belata oge okirikiri.
Teknụzụ a dabere na isi agwakọta graphite pụrụ iche. Isi agwakọta ọhụrụ a dabere na isi agwakọta nnukwu nrụgide KraussMaffei. A na-eji usoro a kwadebere ya na nkwụsị nke nrụgide dị ala nke akụkụ obe na-arịwanye elu ma mee ya maka nhazi graphite gbasaa. N'ihi nke a, a na-ebelata nrụgide n'ibu ọrụ na akụkụ graphite na-agbasawanye n'etiti cycles nke polyol ebubo na-esochi. Tupu ịmalite ịwụsa, ihe ahụ na-ekesa site na nozzle, na-emepụta nrụgide. Ya mere, ihe ndochi ahụ na-enwe obere nrụgide n'ibu. Site na teknụzụ a, ọkwa njuputa dị elu ga-ekwe omume, dabere na ihe achọrọ na usoro akụrụngwa, ihe ruru 30% site na ịdị arọ nke polymer. Ya mere, ọ nwere ike iru elu larịị nke ọkụ na-eguzogide UL94-V0.
Dị ka KraussMaffei si kwuo, a na-akwadebe ngwakọta nke polyol na graphite na-agbasa na ebe a na-agwakọta ihe pụrụ iche. Ndị na-agwakọta ihe pụrụ iche na-agwakọta ihe mejupụtara ya na ihe mmiri mmiri. A na-eme nke a n'ụzọ dị nro, si otú a na-edobe nhazi na nha nke ihe graphite na-agbasawanye. Dosing bụ akpaaka na ịdị arọ polyol nwere ike ịbawanye ruo 80%, na-ahụ na ịdịmma na-agbanwe agbanwe. Na mgbakwunye, mmepụta na-adị ọcha ma na-arụ ọrụ nke ọma ka a na-ewepụ usoro ijikwa aka, itule na njuputa.
N'oge usoro premixing, enwere ike iji ngwakọta nke ịgbasa graphite na ihe ndị ọzọ na-ebuli ibu na oke nke akụrụngwa na-emebighị ihe ndị na-egbochi ọkụ.
