I-Spunlace nonwoven yefiber yangaphambili
Intshayelelo yeMveliso:
Ilaphu le-pre-oxidized filament nonwoven liyinto esebenzayo eyenziwe kwi-filament e-pre-oxidized (i-polyacrylonitrile i-fiber e-oxidized pre-oxidized) ngokusebenzisa iinkqubo ezingabonakaliyo ezifana nenaliti kunye ne-spunlace. Olona ncedo lwayo luselugcinweni lwalo lomlilo. Ayifuni iiretadants ezongezelelweyo zomlilo. Xa ibekwe emlilweni, ayitshi, ayinyibiliki okanye ithontsize. I-carbonizes kuphela kancinci kwaye ayikhuphi iigesi ezinetyhefu xa itshisa, ibonisa ukhuseleko olubalaseleyo.
Okwangoku, inokumelana nobushushu obuphezulu kwaye ingasetyenziswa kwindawo eyi-200-220℃ ixesha elide, kwaye inokumelana namaqondo obushushu angaphezu kwe-400℃ ixesha elifutshane, isagcina amandla omatshini kumaqondo obushushu aphezulu. Xa kuthelekiswa nezixhobo zemveli eziqinileyo ezinqanda amadangatye, ithambile, kulula ukuyisika kunye nokusebenza, kwaye inokudityaniswa nezinye izinto.
Ukusetyenziswa kwayo kugxile kwintsimi yokukhusela umlilo, njengomgangatho wangaphakathi weesuti zomlilo, amakhethini angenamlilo, iileyile zokugquma i-flame-retardant ze-cables, i-flame-retardant linings ye-automotive-interiors, kunye ne-bettery electrode separators, njl.
I-YDL Nonwovens inokuvelisa amalaphu e-pre-oxygenated filament angalukwanga ukusuka kwi-60 ukuya kwi-800 grams, kunye nobukhulu bobubanzi bomnyango bunokwenziwa ngokwezifiso.
Oku kulandelayo kukwazisa kwiimpawu kunye nemimandla yokusetyenziswa kweengcingo zangaphambili ze-oxygenated:
I. Iimpawu eziphambili
I-Intrinsic flame retadancy, ikhuselekile kwaye ayinabungozi: Akukho ziretadanti zongezelelweyo zomlilo ezifunekayo. Ayitshi, inyibilike okanye ithontsize xa ibekwe emlilweni, kodwa ifumana i-carbonization encinci. Ngethuba lenkqubo yokutsha, akukho gesi ezinobuthi okanye umsi onobungozi okhutshwayo, onokuthi uthintele ngokufanelekileyo ukusasazeka kwamadangatye kwaye uhlangabezane nemigangatho ephezulu yokhuseleko.
Ukumelana nobushushu obuphezulu kunye nokugcina imilo elungileyo: Ingasetyenziswa ngokuzinzileyo kwindawo eyi-200-220℃ ixesha elide kwaye inokumelana namaqondo obushushu angaphezu kwama-400℃ ixesha elifutshane. Ayiqhelekanga kwi-deformation okanye i-fracture kwiindawo ezinobushushu obuphezulu kwaye isenokugcina amandla athile omatshini, ukuhlangabezana neemfuno zeemeko zokushisa okuphezulu.
Ubume obuthambileyo kunye nokuqhubekeka okugqwesileyo: Ukuxhomekeka kwinkqubo ye-spunlace, imveliso egqityiweyo ithambile, ithambile kwaye inesandla esihle. Xa kuthelekiswa nefilament ehlatywe ngenaliti pre-oxygenated ilaphu non-elukiweyo okanye izinto zemveli engqongqo flame-retardant (ezifana nelaphu iglasi ifayibha), kulula ukusika nokuthunga, kwaye ingadityaniswa nezinye izinto ezifana umqhaphu kunye polyester ukwandisa iifom zesicelo.
Ukusebenza okusisiseko okuzinzileyo: Inokumelana nokuguga okuthile kunye nokumelana ne-asidi kunye nealkali. Kwiindawo zokugcinwa kwemihla ngemihla okanye kwiindawo eziqhelekileyo zoshishino, akuqhelekanga ukungaphumeleli ngenxa yezinto ezisingqongileyo kwaye unobomi obude benkonzo.
II. Imiba yeSicelo esiPhambili
Kwinkalo yokhuselo lobuqu: Njengomaleko wangaphakathi okanye ilaphu lelaphu leesuti zomlilo, iifaskoti ezikwaziyo ukumelana nomlilo, kunye neeglavu ezikwaziyo ukumelana nobushushu, alidlali nje kuphela indima ekubambezelekeni komlilo kunye nokugquma ubushushu kodwa likwaphucula ukunxitywa kwayo ngokuthambileyo. Ingenziwa kwakhona kwingubo yokubalekela ngokukhawuleza, esetyenziselwa ukugubungela ngokukhawuleza umzimba womntu okanye ukugubungela izinto ezinokutsha kwindawo yomlilo, ukunciphisa umngcipheko wokutsha.
Kwinkalo yokhuseleko lwesakhiwo nekhaya: Isetyenziselwa amakhethini angatshiyo, amacango angatshiyo, kunye neesilingi ezikwaziyo ukumelana namadangatya, ukuhlangabezana nemigangatho yokhuseleko lomlilo wesakhiwo nokuthothisa ukusasazeka komlilo ngaphakathi endlini. Isenako ukusonga iibhokisi zokuhambisa zasekhaya kunye nemibhobho yerhasi, ukunciphisa iingozi zomlilo ezibangelwa yimijikelezo emfutshane yombane okanye ukuvuza kwegesi.
Kwimimandla yezothutho kunye neshishini: Isetyenziswa njengelaphu le-flame-retardant lining yezihlalo, iipaneli zezixhobo kunye neentambo zokubopha ngaphakathi kweemoto kunye noololiwe abahamba ngesantya esiphezulu, ukuhlangabezana nemigangatho yokukhusela umlilo kwizixhobo zokuthutha kunye nokunciphisa umonakalo womsi onetyhefu kwiingozi zomlilo. Isenokusetyenziswa njengesigqumathelo esinganyangekiyo kwiintambo neengcingo ukuthintela ukwanda kwamadangatye kwezinye iindawo xa imigca ibamba umlilo.
Amasimi ancedisayo obushushu obuphezulu: Kwimizi-mveliso yesinyithi, iikhemikhali, kunye namandla, isetyenziswa njengelaphu lokugquma ubushushu kwimisebenzi yobushushu obuphezulu, ukhuselo lwexeshana olungangenwa ngumlilo lokugcinwa kwezixhobo, okanye izinto ezilula zokusonga zemibhobho yobushushu obuphezulu. Inokumelana nokushisa kwexesha elifutshane kwaye kulula ukuyibeka, ukuqinisekisa ukhuseleko lokusebenza.
