➤Isihlukanisi esinganqamuki ilangabi/iphedi yokufaka ukushisa yamabhethri e-lithium

Amabhethri e-lithium (ikakhulukazi amabhethri anamandla) athambekele “ekubalekeni okushisayo” uma eshajwe kakhulu noma efinyezwa isikhashana, nezinga lokushisa likhuphuka ngokuzumayo ngaphezu kuka-300℃. Indwangu ye-pre-oxygenated filament non-woven ingasetshenziswa "njengesehlukanisi sokuphepha" samabhethri e-lithium, afakwe i-sandwed phakathi kwama-electrode amahle namabi: inezici ezithile zokufakelwa ngesikhathi sokusebenza okujwayelekile ukuvimbela izifunda ezimfushane phakathi kwama-electrode amahle nabi. Uma ukugeleza okushisayo kwenzeka, akuncibiliki, kungagcina ubuqotho besakhiwo, ukubambezeleka kokusabalalisa ukushisa, futhi kunciphise ingozi yomlilo nokuqhuma. Ngaphezu kwalokho, ingaphakathi lebhokisi lephakethe lebhethri liphinde lisebenzisa indwangu engalukiwe ye-pre-oxygenated non-woven njengephedi yokuvikela ukuvimbela ukudluliswa kokushisa phakathi kwamaseli ebhethri kanye ne-casing.

➤Izinto zokuvikela izinto zokufakwa kwezingxenye ze-elekthronikhi

Ukupakishwa kwezingxenye ze-elekthronikhi ezifana namabhodi esekethe nama-transformer kudinga ukuvaleka futhi kuvimbele ilangabi. Indwangu engalukiwe ye-pre-oxygenated non-lukiweyo ingenziwa ibe amashidi avikelayo amancane (10-20g/㎡) futhi anamathele ngaphezu kwezingxenye. Ukumelana kwayo nokushisa okuphezulu kungakwazi ukujwayela ukushisa kwendawo ngesikhathi sokusebenza kwemishini ye-elekthronikhi (njengokushisa okusebenzayo kwe-transformer ≤180℃), futhi ngesikhathi esifanayo kuhlangabezane nezinga le-UL94 V-0 le-flame retardant ukuvimbela imijikelezo emifushane nemililo yezingxenye.

4. Ezinye izinkambu ezikhethekile

Ngokungeziwe kulezi zimo ezishiwo ngenhla, indwangu engalukiwe ye-pre-oxygenated filament iphinde ibambe iqhaza kwezinye izinkambu ezikhethekile neziyi-niche:

➤I-Aerospace: Ama-substrate ahlanganisiwe amelana nokushisa okuphezulu

Izinto eziyinhlanganisela ezimelana nezingasindi kanye nezisezingeni eliphezulu ziyadingeka ezingxenyeni zenjini zendiza kanye nezinhlelo zokuvikela ukushisa kwemikhumbi-mkhathi. Indwangu engalukiwe eyenziwe nge-oxidized pre-oxidized ingasetshenziswa njenge-"preform", ehlanganiswe nama-resin (njenge-phenolic resin) ukwenza izinto ezihlanganisiwe. Ngemuva kwe-carbonization, ingenziwa futhi ibe izinto eziyinhlanganisela ye-carbon fibre, ezisetshenziswa ezingxenyeni ezimelana nezinga lokushisa eliphezulu zemikhumbi-mkhathi (njengamacone ekhaleni nemiphetho yamaphiko aphambili) ukuze imelane nokuguguleka kwegesi enezinga eliphezulu lokushisa eligeleza ngaphezu kuka-500℃.

➤Ukuvikelwa kwemvelo: Izinto zokuhlunga eziqinile ezisezingeni lokushisa eliphezulu

Ekwelashweni kwezinsalela zokushisa okuphezulu (okunezinga lokushisa elicishe libe ngu-200-300℃) ngemva kokushiswa kwemfucuza yezokwelapha kanye nemfucumfucu eyingozi, izinto zokuhlunga ziyadingeka ukuze kuhlukaniswe izinsalela negesi. Indwangu engalukiwe ye-pre-oxygenated filament non-woven inokumelana nokugqwala okuqinile futhi ingenziwa ibe izikhwama zokuhlunga ukuze kuhlungwe izinsalela zokushisa okuphezulu, ukuvimbela okokuhlunga ukuthi kungagqwali futhi kuhluleke. Ngesikhathi esifanayo, impahla yayo evimbela amalangabi ivimbela izinto ezivuthayo ezisele ekuthungeleni izinto zokuhlunga.

➤Impahla evikelayo: Izesekeli zamasudi okusebenza akhethekile

Ngaphandle kwamasudi okucisha umlilo, izingubo zokusebenza zemisebenzi ekhethekile njengezimboni ze-metallurgy, i-welding, nezimboni zamakhemikhali nazo zisebenzisa indwangu engalukiwe ye-pre-oxygenated filament njengolwelwesi ezingxenyeni eziguga kalula ezifana nama-cuffs ne-necklines ukuze kuthuthukiswe ukubambezeleka komlilo wendawo nokumelana nokugqokwa, futhi kuvimbele izinhlansi ekuthungeleni izingubo ngesikhathi sokusebenza.

Sengiphetha, ingqikithi yesicelo seIndwangu engalukiwe ye-pre-oxygenated filamentilele ekuthembeleni ezicini zayo eziyinhloko "zokubambezeleka kwelangabi + ukumelana nezinga lokushisa eliphezulu" ukuze kubhekwane nezingozi zokuphepha noma ukushiyeka kokusebenza kwezinto ezivamile ezindaweni ezidlulele. Ngokuthuthukiswa kwezindinganiso zokuphepha ezimbonini ezifana namandla amasha kanye nokukhiqiza okuphezulu, izimo zokusetshenziswa kwayo zizophinde zinwebe zibe izinkambu ezicwengisisiwe nezinevelu eliphezulu (njengokuvikela izingxenye zama-microelectronic kanye nokufakwa kwamadivayisi okugcina amandla aguquguqukayo, njll.).
