III. Izicelo eziphambili ze-Melamine Foam kwi-Battery Thermal Management
Njengoko iimfuno zokhuseleko kwiibhetri zemoto zombane ziqhubeka nokunyuka, i-melamine foam, imathiriyeli esebenzayo yokulawula i-thermal, isetyenziswa ngokubanzi kuyilo lwebhetri. I-Melamine foam inikeza oku kuluncedo kulandelayo:
- Ukusebenza okugqwesileyo kwe-Thermal Insulation:
I-Melamine foam ine-a conductivity ephantsi ye-thermal, ngokwesiqhelo phakathi 0.033 W/m·K kunye ne-0.035 W/m·K, ngokufanelekileyo ukugquma amaqondo obushushu angaphakathi nangaphandle kwipakethi yebhetri, ukuthintela ukubaleka kwe-thermal ngenxa yobushushu obugqithisileyo. Igcina ukusebenza okuzinzileyo kwiindawo eziphezulu zokushisa, iqinisekisa ukushisa okulinganayo ngexesha lokusebenza kwebhetri, ngaloo ndlela iphucula ukhuseleko kunye nokwandisa ubomi bebhetri. - Ukusebenza kakuhle kokufunxa ukothuka:
Xa ipakethe yebhetri ifumana ukungqubana okanye ukungcangcazela, i-melamine foam ifunxa impembelelo, ukukhusela isakhiwo sangaphakathi sebhetri. Ukumelana nokothuka okugqwesileyo kuvela kwi-elasticity ephezulu ye-foam kunye nokukwazi ukugoba. Idatha yovavanyo ibonisa ukuba amandla acinezelayo e-melamine foam anokufikelela 100-150 kPa, ukunciphisa umonakalo obangelwa kukungcangcazela ngexesha lokuthuthwa kwebhetri, ukudibanisa, kunye nokusetyenziswa. - Ukuxhathisa uMlilo:
I-Melamine foam iphezulu ukumelana nomlilo kunciphisa kakhulu umngcipheko womlilo kwiipakethi zebhetri. Yalo isalathisi se-oxygen (OI) ngokuqhelekileyo sisuka kwi-28-30, ebonisa iimpawu ezintle zokuzicima. Inqanaba layo lokumelana nomlilo lidibana nomgangatho we-UL 94 V-0, oku kuthetha ukuba ugwebu aluyi kuvutha okanye lubangele umlilo naphantsi kobushushu obugqithisileyo, okomeleza ukhuseleko lwebhetri iyonke. - KDEName kunye noBulunge kokusiNgqongileyo:
I-Melamine foam ilula, kwaye ingxinano eqhelekileyo ukusuka kuyo 6-50 kg/m³. Xa kuthelekiswa nezinto zemveli zolawulo lwe-thermal, kunciphisa kakhulu ubunzima obupheleleyo bepakethi yebhetri, ukunceda izithuthi zombane zifezekise ukusebenza kakuhle kwamandla. Ukongeza, i-melamine foam idibana nemigangatho emininzi yokusingqongileyo kwaye iyaphinda isetyenziswe, iyenza ibe yinto efanelekileyo yeepakethi zebhetri.
Ngezi zibonelelo ziphambili, i-melamine foam idlala indima ebaluleke kakhulu kulawulo lobushushu bebhetri, ngakumbi ekuphuculeni ukhuseleko lwebhetri yemoto yombane, ukwandisa ubomi bebhetri, kunye nokuphucula ukusebenza kakuhle kwamandla.
Isiphelo:
Njengoko imarike yemoto yombane ikhula ngokukhawuleza, ukhuseleko lwebhetri luye lwaba yinto ekugxilwe kuyo kwihlabathi. I-GB38031-2025, njengomgangatho wamva nje wokhuseleko lwebhetri waseTshayina, ayimiseli kuphela iimfuno ezingqongqo zokhuseleko ngaphakathi kodwa ikwabonelela ngereferensi yophuhliso oluthe kratya lwemigangatho yamazwe ngamazwe. Ngokuthelekisa ne-EU, i-US, kunye nemigangatho yaseJapan, sinokubona iinkxalabo ezifanayo kunye nogxininiso olwahlukileyo kumazwe ngamazwe kummandla wokhuseleko lwebhetri. I-Melamine foam, njengesixhobo esivelisa izinto ezintsha, idlala indima ebalulekileyo ekwandiseni ukhuseleko lwebhetri, ulawulo lwe-thermal, kunye nokumelana nomlilo, kwaye iya kuba yinxalenye ebalulekileyo yoyilo lwebhetri yemoto yombane kwixesha elizayo.
Ukufumana ulwazi oluthe kratya malunga nemigangatho ye-GB38031-2025 okanye ukusetyenziswa kwe-melamine foam kwiibhetri, nceda u tyelele amakhonkco asemgangathweni ahambelanayo okanye uqhagamshelane nathi.
