I-Spunlace engalukiwe yefayibha engaphambi kwe-oxygenated
Imakethe yengxenye:
Izici ze-Pre-Oxygenated Fiber:
· I-Ultimate Flame Retardancy: Umkhawulo we-oxygen index (LOI) ngokuvamile u> 40 (ingxenye ye-oksijini esemoyeni icishe ibe ngu-21%), idlula kude le yemicu evamile ebambezela ilangabi (njenge-polyester evinjwa ilangabi ene-LOI engaba ngu-28-32). Ayincibiliki futhi ayiconsi lapho ichayeke emlilweni, izicisha ngokwayo ngemva kokukhipha umthombo womlilo, futhi ikhipha intuthu encane futhi awekho amagesi anobuthi ngesikhathi sokusha.
Ukuqina Kwezinga Lokushisa Okuphezulu: Izinga lokushisa lokusetshenziswa kwesikhathi eside lingafinyelela ku-200-250 ℃, futhi lesikhashana lingamelana nezinga lokushisa elingu-300-400℃ (ikakhulukazi kuye ngezinto ezingavuthiwe kanye nedigri yangaphambi kwe-oxidation). Isagcina ubuqotho besakhiwo kanye nezakhiwo zemishini ezindaweni ezinezinga lokushisa eliphezulu.
· Ukumelana Namakhemikhali: Inokumelana okuthile nama-asidi, ama-alkali, nezincibilikizi eziphilayo, futhi ayiguguleka kalula amakhemikhali, alungele ukusetshenziswa ezindaweni ezinokhahlo.
· Izinto Ezithile Zomshini: Inamandla athile aqinile nokuqina, futhi ingenziwa ibe izinto ezinesakhiwo esizinzile ngokusebenzisa amasu okucubungula indwangu engalukiwe (njengokubhoboza inaliti, i-spunlace).
II. Ukucubungula Ubuchwepheshe Bezindwangu Ezingenayo I-Pre-Oxygenated Nonwoven
I-fiber efakwe ngaphambili idinga ukucutshungulwa ibe izinto eziqhubekayo ezifana neshidi ngokusebenzisa amasu okucubungula indwangu engalukiwe. Izinqubo ezijwayelekile zihlanganisa:
· Indlela Yokubhoboza Inaliti: Ngokubhoboza ngokuphindaphindiwe i-fiber mesh ngezinaliti zomshini wokubhoboza inaliti, imicu iyahlangana futhi iqinisane, yakha indwangu engalukiwe enogqinsi namandla athile. Le nqubo ifaneleka ukukhiqiza izindwangu ze-fiberless eziqinile, ezinomthamo omkhulu wangaphambi kwe-oxygenated, ezingasetshenziswa ezimweni ezidinga ukusekelwa kwesakhiwo (njengamaphaneli angashi, izinto zokuhlunga ezishisa kakhulu).
· Indlela Eyenziwe Nge-Spunlaced: Ukusebenzisa amajethi amanzi anomfutho ophezulu ukuze kuthinte i-fiber mesh, imicu iyaluka futhi ihlangane. Indwangu efakwe ngaphambili ene-oksijini ephothiwe inomuzwa othambile futhi iphefumula kangcono, futhi ifanele ukusetshenziswa kungqimba lwangaphakathi lwezingubo ezivikelayo, i-flexible padding engashi, njll.
· I-Thermal Bonding/Chemical Bonding: Ngokusebenzisa imicu encibilika-phansi (njenge-polyester engashisi ilangabi) noma izinto ezinamathelayo ukuze zisize ekuqiniseni, ukuqina kwendwangu engenawo umoya-mpilo ehlanzekile yangaphambili kungancishiswa, futhi ukusebenza kokucubungula kungathuthukiswa (kodwa qaphela ukuthi ukumelana nezinga lokushisa kwento enamathelayo kudinga ukuhambisana nendawo yokusetshenziswa komoya-mpilo wangaphambi kwesikhathi).
Ekukhiqizeni kwangempela, imicu yangaphambi kwe-oxidized ivame ukuxutshwa neminye imicu (njenge-aramid, i-viscose e-flame-retardant, i-glass fiber) ukulinganisa izindleko, ukuzwa kanye nokusebenza (isibonelo, indwangu ehlanzekile yangaphambi kwe-oxidized engalukiwe ilukhuni, kodwa ukwengeza i-10-30% ye-viscose evimbela ilangabi kungathuthukisa ukuthambile kwayo).
III. Izimo eziqondile zokusetshenziswa kwendwangu engalukiwe yefayibha esenziwe ngaphambilini
Ngenxa yezindawo zayo ezikwazi ukumelana nelangabi nezingashisi kakhulu, indwangu engalukiwe yefayibha engaphambi kwe-oxid idlala indima ebalulekile emikhakheni eminingi:
1. Ukucima umlilo kanye nokuvikelwa komuntu siqu
· Uhlaka lwangaphakathi / ungqimba lwangaphandle lwe-Firefighter: Indwangu engeyona eyelukiweyo engaphambi kwe-oxidized i-flame-retardant, izinga lokushisa eliphezulu ukumelana nokuphefumula, futhi ingasetshenziswa njengesendlalelo esiyinhloko sezingubo zokucima umlilo ukuvimbela ukudluliswa kwamalangabi namazinga okushisa aphezulu, ukuvikela isikhumba sabacishi bomlilo; uma ihlanganiswe ne-aramid, ingabuye ithuthukise ukumelana nokugqoka kanye nokumelana nokukhala.
· Imishini yokuvikela yokushisela/yensimbi: Isetshenziselwa ukushisela ama-mask linings, amagilavu angangeni ekushiseni, amaphinifa ezisebenzi ze-metallurgical, njll., ukumelana nezinhlansi ezindizayo kanye nemisebe enezinga eliphezulu lokushisa (okunokumelana nezinga lokushisa okungaphezu kuka-300°C).
· Izimpahla zokubalekela izimo eziphuthumayo: Njengezingubo zokucisha umlilo, izinto zokuhlunga imaski, ezingasonga umzimba noma zihlunge intuthu ngesikhathi somlilo (intuthu ephansi kanye nokungabi nobuthi kubaluleke kakhulu).
2. Ukuvikelwa kwezinga lokushisa eliphezulu kanye nokufakwa kwe-insulation
· Izinto zokuhlanganisa izimboni: Zisetshenziswa njengolwelwesi lwangaphakathi lwamapayipi okushisa okuphezulu, ama-boiler insulation pads, njll., ukunciphisa ukulahlekelwa ukushisa noma ukudlulisa (ukumelana isikhathi eside ku-200 ° C nangaphezulu kwezindawo).
· Izinto zokwakha ezingashi: Njengongqimba olugcwaliswayo lwamakhethini angashi kanye nezindonga zomlilo ezakhiweni eziphakeme kakhulu, noma izinto zokumboza ngekhebula, ukuze kubambezeleke ukusabalala komlilo (okuhlangabezana ne-GB 8624 yokumelana nomlilo ibanga B1 nangaphezulu).
· Ukuvikelwa kwempahla yokushisa okuphezulu: Okufana namakhethini kahhavini, izembozo zokufudumeza ukushisa zamahhavini namahhavini, ukuvimbela abasebenzi ukuthi bangashiswa indawo eshisa kakhulu yezinto zokusebenza.
3. Izinkambu zokuhlunga kwezinga lokushisa eliphezulu
· Ukuhlunga kwegesi yentuthu yezimboni: Izinga lokushisa legesi yentuthu evela kumshini wokushisisa udoti, izigayo zensimbi, iziko lokusabela amakhemikhali ngokuvamile lifinyelela ku-200-300°C, futhi liqukethe amagesi ane-asidi. Indwangu engalukiwe efakwe ngaphambili i-oxidized imelana namazinga okushisa aphezulu kanye nokugqwala, futhi ingasetshenziswa njengento eyisisekelo yezikhwama zokuhlunga noma amasilinda okuhlunga, isihlungi ngokuphumelelayo.
4. Ezinye izimo ezikhethekile
Izinto ezisizayo ze-Aerospace: zisetshenziswa njengezendlalelo zokuvikela umlilo ezingangeni ngaphakathi kwamakhebhini emikhumbi-mkhathi kanye namagesi okuvikela ukushisa azungeze izinjini zamarokhethi (okudingeka ziqiniswe ngezinsalela ezimelana nezinga lokushisa eliphezulu).
Izinto zokuvikela ugesi zikagesi: Asetshenziswa njengama-gaskets afaka i-insulating kumamotho anezinga lokushisa eliphezulu nama-transformer, angashintsha izinto ze-asbestos zendabuko (ezingezona i-carcinogenic futhi ezinobungani nemvelo).
Iv. Izinzuzo namathrendi okuthuthuka kwe-Pre-Oxidized fiber Nonwoven Fabrics
Izinzuzo: Uma kuqhathaniswa nezinto ezivamile ezivimbela amalangabi (njenge-asbestos nefayibha yengilazi), indwangu ye-pre-oxygenated non-rukiweyo ayiyona i-carcinogenic futhi inokuvumelana nezimo kangcono. Uma kuqhathaniswa namafayibha anenani eliphezulu njenge-aramid, inenani eliphansi (cishe i-1/3 kuya ku-1/2 ye-aramid) futhi ifaneleka ekusetshenzisweni kwenqwaba ezimweni ezimaphakathi nezisezingeni eliphezulu zokunqanda ilangabi.
Ithrendi: Thuthukisa ukubumbana nokusebenza kahle kokuhlunga kwezindwangu ezingalukiwe ngokucolisiswa kwefayibha (njengemicu emihle ye-denier pre-oxygenated, ububanzi obungu-< 10μm); Thuthukisa amasu okucubungula emvelo nge-formaldehyde ephansi futhi akukho okunamathelayo; Ihlanganiswe nama-nanomaterials (njenge-graphene), iphinde ithuthukise ukumelana nezinga lokushisa eliphezulu kanye nezakhiwo zokulwa namagciwane.
Sengiphetha, ukusetshenziswa kwemicu yangaphambi kwe-oxidized ezindwangu ezingezona ezilukiwe kuncike ezintweni zazo eziyinhlanganisela "yokunqanda ilangabi nokumelana nokushisa okuphezulu" ukuze kubhekwane nokushiyeka kokusebenza kwezinto zendabuko endaweni yokushisa ephezulu nevulekile. Ngokuzayo, ngokuthuthukiswa kwamazinga okuphepha kwezimboni kanye nokuvikela umlilo, izimo zokusetshenziswa kwazo zizonwetshwa ngokuqhubekayo.
