Kuzunguruka idahwitse ya fibre mbere ya ogisijeni
Isoko ry'igice:
Ibiranga Fibre Yabanjirije Oxygene:
· Ultimate Flame Retardancy: Umubare ntarengwa wa ogisijeni (LOI) mubisanzwe ni> 40 (igipimo cya ogisijeni mu kirere kigera kuri 21%), kikaba kirenze kure icy'ibisanzwe bisanzwe bya flame-retardant fibre (nka polyester flame-retardant polyester hamwe na LOI ya 28-32). Ntishobora gushonga cyangwa gutonyanga iyo ihuye numuriro, irazimya nyuma yo gukuraho inkomoko yumuriro, kandi irekura umwotsi muke kandi nta myuka yubumara mugihe cyo gutwikwa.
· Ubushyuhe bwo hejuru cyane: Ubushyuhe bwigihe kirekire bwo gukoresha bushobora kugera kuri 200-250 and, kandi mugihe gito gishobora kwihanganira 300-400 temperatures ubushyuhe bwo hejuru (cyane cyane bitewe nibikoresho fatizo na dogere mbere ya okiside). Iracyakomeza uburinganire bwimiterere nubukanishi mubushyuhe bwo hejuru.
· Kurwanya imiti: Ifite imbaraga zimwe na zimwe zirwanya aside, alkalis, hamwe n’umuti ukomoka ku binyabuzima, kandi ntishobora kwangirika byoroshye n’ibintu bya shimi, bikwiriye gukoreshwa ahantu habi.
· Ibintu bimwe na bimwe bya mashini: Ifite imbaraga nuburemere bukomeye, kandi irashobora gukorwa mubikoresho bifite imiterere ihamye binyuze muburyo bwo gutunganya imyenda idoda (nko gukubita inshinge, spunlace).
II. Gutunganya Ikoranabuhanga rya Pre-Oxygene Imyenda idahwitse
Fibre mbere ya ogisijeni igomba gutunganyirizwa mubikoresho bikomeza kumpapuro nkuburyo bwo gutunganya imyenda. Inzira zisanzwe zirimo:
· Uburyo bwo gukubita inshinge: Mugutobora inshuro nyinshi inshundura ya fibre inshinge za mashine-inshinge, fibre irahuza kandi igakomezanya, ikora umwenda udoda hamwe nubunini n'imbaraga runaka. Iyi nzira irakwiriye kubyara ingufu nyinshi, zifite ubucucike bwinshi mbere ya ogisijeni ya fibre idafite fibre, ishobora gukoreshwa mugihe gisaba ubufasha bwubatswe (nkibikoresho bidafite umuriro, ibikoresho byo kuyungurura ubushyuhe).
· Uburyo butandukanye: Gukoresha indege zamazi yumuvuduko mwinshi kugirango bigire ingaruka kuri fibre mesh, fibre irahuza kandi igahuza hamwe. Umwenda ubanziriza ogisijeni ufite ibyiyumvo byoroheje kandi uhumeka neza, kandi ukwiriye gukoreshwa murwego rwimbere rwimyenda ikingira, padi yoroheje yumuriro, nibindi.
· Guhuza Ubushyuhe / Guhuza imiti: Ukoresheje fibre-e-point-fibre fibre (nka flame-retardant polyester) cyangwa ibifatika kugirango bifashe mu gushimangira, ubukana bwimyenda yera itabanjirije okisijeni irashobora kugabanuka, kandi imikorere yo gutunganya irashobora kunozwa (ariko menya ko ubushyuhe bwubushyuhe bwumuti bukenera guhuza ibidukikije bikoreshwa mbere yimyenda ya ogisijeni).
Mu musaruro nyirizina, fibre yabanjirije okiside ikunze kuvangwa nizindi fibre (nka aramid, flame-retardant viscose, fibre yikirahure) kugirango iringanize ikiguzi, ibyiyumvo nibikorwa (urugero, umwenda wera mbere ya okiside utaboshywe biragoye, ariko wongeyeho 10-30% viscose ya flame-retardant irashobora kunoza ubworoherane).
III. Porogaramu yihariye ya progaramu ya-okiside fibre idoda
Bitewe na flame-retardant hamwe nubushyuhe bwo hejuru bwo kwihanganira ubushyuhe, fibre mbere ya okiside fibre idoda idoda igira uruhare runini mubice byinshi:
1. Kurwanya umuriro no kurinda umuntu ku giti cye
· Imbere yumuriro / imbere yinyuma: Imyenda ibanziriza okisiside idahwitse ni flame-retardant, irwanya ubushyuhe bwinshi kandi ihumeka, kandi irashobora gukoreshwa nkurwego rwibanze rwimyenda yo kuzimya umuriro kugirango ihagarike ihererekanyabubasha nubushyuhe bwinshi, birinda uruhu rwabashinzwe kuzimya umuriro; iyo ihujwe na aramid, irashobora kandi kunoza imyambarire no kurwanya amarira.
· Ibikoresho byo gukingira / gusudira: Gukoreshwa mu gusudira imirongo ya mask, uturindantoki twirinda ubushyuhe, feri y'abakozi ba metallurgji, n'ibindi, kugira ngo wirinde ibicanwa biguruka n'imirasire y'ubushyuhe bwo hejuru (hamwe n'ubushyuhe bw'igihe gito burenga 300 ° C).
· Ibikoresho byo guhunga byihutirwa: nkibiringiti byumuriro, ibikoresho byo guhunga mask, bishobora gupfunyika umubiri cyangwa kuyungurura umwotsi mugihe cyumuriro (umwotsi muke nuburozi ni ngombwa cyane).
2. Inganda zo mu rwego rwo hejuru kurinda ubushyuhe no gukumira
· Ibikoresho byokwirinda inganda: Byakoreshejwe nkimbere yimbere yimiyoboro yubushyuhe bwo hejuru, amashuka yimashini, nibindi, kugirango ugabanye ubushyuhe cyangwa kwimurwa (kurwanya igihe kirekire kuri 200 ° C no hejuru yibidukikije).
· Ibikoresho byubaka umuriro: Nkurwego rwuzuza umwenda utwikiriye umuriro hamwe nu muriro mu nyubako ndende, cyangwa ibikoresho byo gutwika insinga, kugirango bidindiza ikwirakwizwa ry’umuriro (byujuje ibyiciro bya GB 8624 birwanya umuriro B1 nibisabwa hejuru).
· Kurinda ibikoresho byubushyuhe bwo hejuru: Nkumwenda wifuru, gutwikira ubushyuhe bwamashyiga n’itanura, kugirango abakozi batwikwa nubushyuhe bwo hejuru bwibikoresho.
3. Ubushyuhe bwo hejuru bwo kuyungurura
· Akayunguruzo ka gaze mu nganda: Ubushyuhe bwa gaze yumwotsi uva mu gutwika imyanda, mu ruganda rukora ibyuma, itanura ry’imiti akenshi igera kuri 200-300 ° C, kandi irimo imyuka ya aside. Imyenda ibanziriza okiside idashobora kuboha irwanya ubushyuhe bwinshi no kwangirika, kandi irashobora gukoreshwa nkibikoresho fatizo kumifuka yo kuyungurura cyangwa silinderi, kuyungurura neza.
4. Ibindi bintu bidasanzwe
Ibikoresho bifasha mu kirere: bikoreshwa nk'ibikoresho byo gutwika umuriro imbere mu kazu k’icyogajuru hamwe na gasketi yo kubika ubushyuhe bikikije moteri ya roketi (bigomba gushimangirwa n'ibisigazwa by’ubushyuhe bwo hejuru).
Ibikoresho bitanga amashanyarazi: Byakoreshejwe nka gasketi ya moteri muri moteri yubushyuhe bwo hejuru hamwe na transformateur, birashobora gusimbuza ibikoresho bya asibesitosi gakondo (bitari kanseri kandi bitangiza ibidukikije).
Iv. Ibyiza hamwe niterambere ryiterambere rya Oxidized fibre Imyenda idoda
Ibyiza: Ugereranije nibikoresho gakondo bya flame-retardant (nka asibesitosi na fibre yikirahure), fibre mbere ya ogisijeni fibre idoda idoda ntabwo ari kanseri kandi ifite ihinduka ryiza. Ugereranije na fibre ihenze cyane nka aramid, ifite igiciro gito (hafi 1/3 kugeza 1/2 cya aramid) kandi irakwiriye gukoreshwa mugice cyo hagati kandi cyanyuma-flame-retardant scenarios.
Icyerekezo: Kuzamura ubwuzuzanye no kuyungurura imikorere yimyenda idoda binyuze mugutunganya fibre (nko guhakana neza mbere ya ogisijeni ya filime, diameter <10μm); Gutezimbere uburyo bwo gutunganya ibidukikije bitangiza ibidukikije hamwe na forode nkeya kandi nta bifata; Hamwe na nanomateriali (nka graphene), irusheho kongera ubushyuhe bwo hejuru hamwe na antibacterial.
Mu gusoza, ikoreshwa rya fibre yabanjirije okiside mumyenda idoda idoda ishingiye kumiterere yabyo ya "flame retardancy and high-temperature resistance" kugirango ikemure imikorere mibi yibikoresho gakondo mubushyuhe bwinshi kandi ahantu hafunguye umuriro. Mu bihe biri imbere, hamwe no kuzamura umutekano w’inganda no kurinda umuriro, ibintu bizashyirwa mu bikorwa.
