Spunlace nonwoven na pre-oxygenated fiber
Kasuwar kashi:
Halayen Fiber-Oxygenated Pre-Oxygenated:
Ƙarshen Harshen Harshen Wuta: Iyakar iskar oxygen (LOI) yawanci> 40 (yawan iskar oxygen a cikin iska shine kusan 21%), wanda ya zarce na filaye masu ɗaukar harshen wuta na al'ada (kamar polyester mai kare harshen wuta tare da LOI na kusan 28-32). Ba ya narke ko digo a lokacin da aka fallasa wuta, yana kashe kansa bayan cire tushen wuta, kuma yana sakin hayaki kaɗan kuma babu iskar gas mai guba yayin konewa.
· High-Zazzabi Tsaya: The dogon lokacin amfani zazzabi iya isa 200-250 ℃, da kuma gajeren lokaci iya jure 300-400 ℃ high yanayin zafi (musamman dangane da albarkatun kasa da pre-oxidation digiri). Har yanzu yana kiyaye amincin tsari da kaddarorin inji a cikin yanayin zafi mai zafi.
· Juriya na sinadarai: Yana da takamaiman juriya ga acid, alkalis, da sauran abubuwan da ake amfani da su, kuma ba a sauƙaƙe ta hanyar sinadarai, wanda ya dace da amfani da shi a cikin matsanancin yanayi.
Wasu Abubuwan Kayayyakin Injini: Yana da ƙayyadaddun ƙarfi da ƙarfi, kuma ana iya sanya shi su zama kayan aiki masu tsayayyen tsari ta hanyar dabarun sarrafa masana'anta (kamar naushin allura, spunlace).
II. Fasahar Sarrafa Na'urorin da ba a saka da Oxygenated Pre-Oxygenated Non Woven Fabrics
Ana buƙatar sarrafa fiber ɗin da aka rigaya ya cika iskar oxygen zuwa kayan ci gaba mai kama da takarda ta hanyar dabarun sarrafa masana'anta. Hanyoyin gama gari sun haɗa da:
· Hanyar bugun allura: Ta hanyar huda ragamar fiber akai-akai tare da alluran injin allura, zaruruwan suna yin cuɗanya da ƙarfafa juna, suna samar da masana'anta mara saƙa da wani kauri da ƙarfi. Wannan tsari ya dace da samar da kayan aiki masu ƙarfi, masu girma da yawa pre-oxygenated fiberless yadudduka, wanda za'a iya amfani dashi a cikin al'amuran da ke buƙatar goyon bayan tsarin (kamar bangarori na wuta, kayan tacewa mai zafi).
· Hanyar Spunlaced: Yin amfani da manyan jiragen ruwa masu matsa lamba don yin tasiri akan ragar fiber, filayen suna saƙa da haɗin gwiwa tare. Yaduwar da aka riga aka yi da iskar oxygen ta spunlaced tana da taushin jin daɗi da mafi kyawun numfashi, kuma ya dace da amfani da shi a cikin rufin ciki na tufafin kariya, sassauƙan mai hana wuta, da dai sauransu.
Ƙimar thermal / Chemical bonding: Ta yin amfani da ƙananan zaruruwa masu narkewa (irin su polyester mai riƙe da wuta) ko adhesives don taimakawa wajen ƙarfafawa, za a iya rage ƙaƙƙarfan masana'anta na fiberless pre-oxygenated mai tsabta, kuma ana iya inganta aikin sarrafawa (amma lura cewa juriya na mannewa yana buƙatar dacewa da yanayin amfani da masana'anta na pre-oxygen).
A cikin ainihin samarwa, ƙwayoyin da aka riga aka yi amfani da su sau da yawa ana haɗe su da sauran fibers (irin su aramid, viscose-retardant viscose, gilashin fiber) don daidaita farashi, jin dadi da aiki (alal misali, rigar da aka riga aka rigaya ba a saka ba yana da wuyar gaske, amma ƙara 10-30% viscose mai saurin wuta zai iya inganta laushinsa).
III. Takamaiman yanayin aikace-aikacen masana'anta na fiber da ba a saka ba kafin-oxidized
Saboda kaddarorin da ke jurewa harshen wuta da yanayin zafi, masana'anta na fiber da ba a saka ba da aka riga aka yi oxidized suna taka muhimmiyar rawa a fannoni da yawa:
1. kashe gobara da kariya ta sirri
· Layi na ciki / na waje mai kashe gobara: Kayan da ba a saka ba da aka riga aka yi da oxidized ba shi da wuta, mai juriya mai zafi da numfashi, kuma ana iya amfani da shi azaman babban layin kashe gobara wanda ya dace don toshe canja wurin wuta da yanayin zafi, yana kare fata na masu kashe gobara; idan aka hada shi da aramid, yana iya inganta juriya da juriya.
· Kayan aikin kariya na walda / ƙarfe: Ana amfani da su don walda abin rufe fuska, safofin hannu masu jurewa zafi, atamfa na ma'aikatan ƙarfe, da dai sauransu, don tsayayya da tartsatsin tashi da zafi mai zafi (tare da juriya na ɗan gajeren lokaci na sama da 300 ° C).
· Kayayyakin tserewa na gaggawa: Irin su bargo na wuta, kayan tace abin rufe fuska, wanda zai iya nade jiki ko tace hayaki yayin wuta (ƙananan hayaki da rashin guba suna da mahimmanci musamman).
2. Masana'antu high-zazzabi kariya da rufi
· Kayayyakin rufin masana'antu: An yi amfani da shi azaman rufin ciki na bututu masu zafi, matattarar rufin tukunyar jirgi, da dai sauransu, don rage asarar zafi ko canja wuri (tsawon tsayin lokaci zuwa 200 ° C da sama da mahalli).
· Kayan gini mai hana wuta: A matsayin cika Layer na labule masu hana wuta da bangon wuta a cikin manyan gine-gine, ko kayan rufin kebul, don jinkirta yaduwar wuta (cima da GB 8624 juriya na wuta B1 da buƙatun sama).
· Kariyar kayan aiki mai zafi: Kamar labulen tanderu, murfin zafi don murhun wuta da tanda, don hana ma'aikata konewa ta yanayin zafin na'urar.
3. Filayen tacewa mai zafi
· Tace gas hayaki na masana'antu: Yanayin zafin iskar hayaƙi daga injin incinerators, masana'antar ƙarfe, tanderun amsa sinadarai yakan kai 200-300 ° C, kuma yana ɗauke da iskar acidic. Pre-oxidized ba saka masana'anta ne resistant zuwa high yanayin zafi da kuma lalata, kuma za a iya amfani da matsayin tushe abu ga tace jaka ko tace cylinders, nagarta sosai tace.
4. Wasu yanayi na musamman
Kayayyakin taimako na sararin samaniya: ana amfani da shi azaman yadudduka masu hana wuta a cikin ɗakunan kumbon kumbo da keɓaɓɓun gas ɗin zafi a kusa da injunan roka (waɗanda ke buƙatar ƙarfafawa tare da resins masu jure zafin jiki).
Kayayyakin insulating na Wutar Lantarki: Ana amfani da su azaman insulating gaskets a cikin injuna masu zafin jiki da masu canza wuta, za su iya maye gurbin kayan asbestos na gargajiya (marasa cutar kansa da ƙari ga muhalli).
Iv. Abũbuwan amfãni da Ci gaban Ci gaba na Pre-Oxidized fiber Nonwoven Fabrics
Abũbuwan amfãni: Idan aka kwatanta da kayan gargajiya na al'ada (irin su asbestos da fiber gilashi), fiber da ba a saƙa da aka rigaya ba da oxygen ba shi da ciwon daji kuma yana da mafi kyawun sassauci. Idan aka kwatanta da filaye masu tsada irin su aramid, yana da ƙananan farashi (kimanin 1/3 zuwa 1/2 na aramid) kuma ya dace da aikace-aikacen batch a matsakaici da matsakaicin yanayin wuta-retardant.
Trend: Haɓaka haɓakar haɓakawa da tacewa na kayan da ba a saka ba ta hanyar gyaran fiber (kamar ƙarancin filament pre-oxygenated, diamita <10μm); Haɓaka dabarun sarrafawa masu dacewa da muhalli tare da ƙarancin formaldehyde kuma babu adhesives; Haɗe tare da nanomaterials (irin su graphene), yana ƙara haɓaka juriya mai zafi da kaddarorin ƙwayoyin cuta.
A ƙarshe, aikace-aikace na pre-oxidized zaruruwa a cikin wadanda ba saka yadudduka hinges a kan hadaddun kaddarorin na " harshen wuta retardancy da high-zazzabi juriya "don magance yi shortcomings na gargajiya kayan a high-zazzabi da kuma bude harshen wuta yanayi. A nan gaba, tare da haɓaka amincin masana'antu da ka'idodin kariyar wuta, za a ƙara faɗaɗa yanayin aikace-aikacen su.
