Ngaphakathi engxoweniumqokeleli wothuli, uthuli olunongquzulwano lokuhamba komoya, uthuli kunye nelaphu lokucoca impembelelo yelaphu luya kuvelisa umbane ongatshintshiyo, uthuli lwemizi-mveliso ngokubanzi (njengothuli olungaphezulu, uthuli lweekhemikhali, uthuli lwamalahle, njl.njl.) emva kokuba ugxininiso lufikelela kwinqanaba elithile (oko kukuthi, Umda wokudubula), okufana neentlantsi zokukhutshwa kwe-electrostatic okanye ukuvutha kwangaphandle kunye nezinye izinto, ezikhokelela ngokulula kugqabhuko-dubulo nomlilo. Ukuba olu thuli luqokelelwa ngeengxowa zelaphu, izinto zokucoca kufuneka zibe nomsebenzi ochasayo. Ukuphelisa ukuqokelelwa kwentlawulo kwizinto zokucoca, iindlela ezimbini zihlala zisetyenziselwa ukuphelisa umbane omileyo wesixhobo sokucoca:
(1) Kukho iindlela ezimbini zokusebenzisa i-antistatic agents ukunciphisa ukuxhathisa komphezulu kwimicu yekhemikhali: ①Ukuncamathelwa kwee-antistatic agents zangaphandle kumphezulu wemicu yekhemikhali: ukuncamathelwa kwee-ion zehygroscopic okanye ii-non-ionic surfactants okanye iipolima zehydrophilic kumphezulu wemicu yemichiza. , ukutsala iimolekyuli zamanzi emoyeni, ukwenzela ukuba umphezulu wemicu yemichiza wenze ifilimu yamanzi encinci kakhulu. Ifilimu yamanzi inokutshabalalisa i-carbon dioxide, ukwenzela ukuba ukuchasana kwendawo kuncitshiswe kakhulu, ukwenzela ukuba intlawulo ingabi lula ukuqokelela. ② Ngaphambi kokuba i-fiber yekhemikhali izotywe, i-agent ye-antistatic yangaphakathi yongezwa kwi-polymer, kwaye i-molecule ye-antistatic ye-antistatic isasazwa ngokufanayo kwi-fiber yekhemikhali eyenziweyo ukwenza isiphaluka esifutshane kunye nokunciphisa ukuxhathisa kwe-chemical fiber ukufezekisa umphumo we-antistatic.
(2) Ukusetyenziswa kwemicu ye-conductive: kwimveliso yeekhemikhali zefiber, yongeza inani elithile lemicu ye-conductive, usebenzisa umphumo wokukhutshwa ukususa umbane osisigxina, ngokwenene, umgaqo wokukhutshwa kwe-corona. Xa iimveliso zefiber zekhemikhali zinombane ongatshintshiyo, umzimba ohlawulweyo uyakhiwa, kwaye intsimi yombane yenziwa phakathi komzimba ohlawuliweyo kunye nefayibha eqhubayo. Le ntsimi yombane igxininiswe malunga ne-fiber conductive, ngaloo ndlela yenza intsimi yombane eyomeleleyo kwaye yenza ummandla wokusebenza we-ionized wendawo. Xa kukho i-corona encinci, ii-ion ezilungileyo kunye ne-negative ziveliswa, ii-ion ezingalunganga zifudukela kumzimba ohlawulisiweyo kwaye ii-ion ezithandekayo zivuza kumzimba ophantsi nge-fiber conductive, ukuze kuphunyezwe injongo yombane ochasayo. Ukongeza kwi-conductive yentsimbi esetyenziswa ngokuqhelekileyo, i-polyester, i-acrylic conductive fiber kunye ne-carbon fiber inokufumana iziphumo ezilungileyo. Kwiminyaka yakutshanje, ngophuhliso oluqhubekayo lwe-nanotechnology, iipropathi ezikhethekileyo zokuqhuba kunye ne-electromagnetic, i-super absorbency kunye ne-wide band properties ze-nanomaterials ziya kusetyenziswa ngakumbi kwi-conductive absorbing fabrics. Umzekelo, i-carbon nanotubes yi-conductor yombane egqwesileyo, esetyenziswa njengesongezo esisebenzayo ukuyenza ihlakazwe ngokuzinzileyo kwisisombululo se-chemical fiber spinning, kwaye inokwenziwa kwiipropathi ezilungileyo zokuqhuba okanye i-antistatic fibers kunye namalaphu kwiindawo ezahlukeneyo ze-molar.
3 I-Polyimide fiber i-P84 yinto ephikisayo, isantya somsi esiphantsi, ngokuzicima, xa isitsha, nje ukuba umthombo womlilo ushiye, ngokukhawuleza uzicime. Isixhobo sokucoca esenziwe kuyo sinokulibaziseka okuhle komlilo. Isixhobo sokucoca i-JM esiveliswe nguJiangsu Binhai Huaguang isihluzo sothuli Ilaphu lomzi-mveliso, isalathiso saso sokunciphisa i-oksijini sinokufikelela kuma-28 ~ 30%, ukutshiswa okuthe nkqo kufikelela kwinqanaba le-B1 lamazwe ngamazwe, ngokusisiseko kunokufikelela injongo yokucima umlilo, luhlobo lwesihluzo. impahla enelangatye elungileyo. Izixhobo ze-nano-composite ze-flame retardant ezenziwe nge-nanotechnology i-nano-sized inorganic flame retardants i-nano-sized, i-nano-scale Sb2O3 njenge-carrier, ukuguqulwa komphezulu kungenziwa kwii-retardants ezisebenza kakuhle zomlilo, isalathisi sayo se-oksijini siphindaphinda kaninzi kunezinye ii-flame retardants eziqhelekileyo.
