Itekhnoloji ye-KraussMaffei eyandisiweyo yedosi yegraphite ivumela imathiriyeli ukuba isetyenziswe njengesixhobo somlilo, indawo okanye ukongeza kwimixube engamanzi.
Iimfuno zokumelana nomlilo weendawo ze-polyurethane ze-foam ziyanda kwihlabathi jikelele, zombini kumacandelo eemoto kunye nezoshishino, kunye nangenxa yeemfuno zokulawula. Ukuhlangabezana nale mfuno, iKraussMaffei (eMunich, eJamani) yazisa ukuba iya kubonisa inkqubo epheleleyo yoxinzelelo oluphezulu lwegraphite ekwandiswayo ukufezekisa izinto eziphezulu kunye nokusebenza kakuhle kwenkqubo, kwaye umboniso weMveliso yoCwangciso uya kubanjelwa eDüsseldorf, eJamani ukususela ngo-Oktobha 16 ukuya. 2017 unyaka. 19th.
"I-graphite eyandisiweyo yi-filler eneendleko ezibonelela ngeenzuzo ezicacileyo kwizicelo ezininzi ezizenzekelayo," kuchaza uNicholas Bale, uMongameli weCandelo leSixhobo seReaction eKraussMaffei. Ngelishwa, esi sixhobo sinovelwano kuxinzelelo lomatshini ngexesha lokusetyenzwa.
Intloko yeKraussMaffei esanda kuphuhliswa yoxinzelelo oluphezulu kunye ne-low-pressure bypass kunye nesikhululo esikhethekileyo sokuxutywa kwangaphambili sokuxuba igraphite eyandisiweyo iyenza ibe yeyona ndlela isebenzayo okanye isongezo kwizongezo zolwelo njengesithinteli somlilo. Amakhonkco enkqubo ezenzekelayo ngokupheleleyo anciphisa amaxesha omjikelezo wecandelo kunye nokwandisa ukusebenza kakuhle kwenkqubo.
U-KraussMaffei ubanga ukuba izibonelelo ze-high-pressure countercurrent injection mixing ye-precision machining ye-polyurethane foam systems esebenzayo kakhulu ingasetyenziswa kwizicelo apho i-graphite eyandisiweyo isetyenziswa njenge-filler. Oku kuxelwe ukuba sisiseko sokunciphisa amaxesha omjikelezo kunye nokwandisa ukusebenza kakuhle kwemveliso. Kule nkqubo, ngokungafaniyo nokucutshungulwa koxinzelelo oluphantsi, intloko yokuxuba yokucoca ngokuzicoca ithi ikhuphe imfuno yokugungxulwa emva kwesitofu ngasinye. UKraussMaffei uthi oku konga izixhobo kunye nexesha lokuvelisa kwaye kunceda ukugcina umgangatho wemveliso ongaguqukiyo, ngelixa ususa iindleko zokubonelela kunye nokulahla izinto ezigungxulwayo. Ukuxubana koxinzelelo oluphezulu nako kufezekisa amandla aphezulu okuxuba. Oku kungasetyenziselwa ukunciphisa ixesha lomjikelo.
Le teknoloji isekelwe kwiintloko ezikhethekileyo zokuxuba igraphite. Intloko entsha yokuxuba isekelwe kwintloko ye-KraussMaffei yoxinzelelo oluphezulu. Inkqubo ixhotyiswe nge-low-pressure bypass ye-cross-section eyandisiweyo kwaye yenzelwe ukusetyenzwa kwegraphite eyandisiweyo. Ngenxa yoko, uxinzelelo lomatshini olwenziwa kulwandiso lwamasuntswana egraphite phakathi komjikelo wemijikelo elandelelanayo yepolyol ehlawuliswayo iyancitshiswa. Ngaphambi nje kokugalela kuqala, izinto zijikeleza nge-nozzle, zidala uxinzelelo. Ke ngoko, isigcwalisi siphantsi koxinzelelo oluncinci lomatshini. Ngale teknoloji, amanqanaba aphezulu okuzalisa anokwenzeka, kuxhomekeke kwiimfuno kunye nenkqubo yezinto eziluhlaza, ukuya kuthi ga kwi-30% ngesisindo sepolymer. Ke ngoko, inokufikelela kwinqanaba eliphezulu lokumelana nomlilo UL94-V0.
Ngokutsho kweKraussMaffei, umxube we-polyol kunye nokwandisa igraphite ilungiselelwe kwisikhululo esikhethekileyo sokuxuba kwangaphambili. Abaxumi abakhethekileyo badibanisa ngokulinganayo ukuzaliswa kunye nezithako zamanzi. Oku kwenziwa ngendlela ethambileyo, ngaloo ndlela kugcinwe isakhiwo kunye nobukhulu beengqungquthela zegraphite ezandiswayo. Idosi iyazenzekela kwaye ubunzima bepolyol bunokunyuswa ukuya kuthi ga kwi-80%, kuqinisekiswe umgangatho ongaguqukiyo. Ukongeza, imveliso iba icocekile kwaye isebenze ngakumbi njengoko ukuphathwa ngesandla, ukulinganisa kunye nokuzalisa amanyathelo apheliswa.
Ngethuba lenkqubo yokuxutywa kwe-premixing, umlinganiselo wokuxuba wokwandisa igraphite kunye namanye amacandelo angasetyenziselwa ukwandisa ubunzima kunye nomthamo wamacandelo ngaphandle kokunciphisa iipropati zomlilo.
