Imyenda yo kurwanya umuriro

Kurwanya umuriroikositimuni imyenda ikingira abashinzwe kuzimya umuriro bambara kugirango birinde kugirango binjire aho basanzwe umuriro kugirango barwanye umuriro, kandi birakwiriye gukoreshwa mumiterere "isanzwe" yumuriro.Kuzimya umuriroikositimubigabanijwemo mirongo inani na gatanu na mirongo cyenda na karindwi.Benshi mu bakinnyi bashinzwe kuzimya umuriro bafite ibikoresho 85 byo kuzimya umuriroikositimu, igabanijwemo ubwoko bune: imyenda yimbeho, imyenda yo mu cyi, imyenda idacana umuriro n imyenda idakoresha amazi, n imyenda ndende yo kuzimya umuriro.Birakwiriye kurwanira umuriro muri rusange kandi ntibikwiriye kubikorwa by-umuriro no gutabara byihutirwa..Imyambaro yo kurwana 97 ni ubushakashatsi bushya bwo kurwanya umuriroikositimu, ifite imirimo yo gukumira inkongi y'umuriro, kutagira umuriro, kubika ubushyuhe na anti-virusi, kandi ibereye kurwanya umuriro ndetse n’ibikorwa bimwe na bimwe byo gutabara byihutirwa.

Imikorere yo gukingira hamwe nuburyo bujyanye no gupima imyenda yo kurwanya umuriro igomba kuba ifite

(1) Imikorere ya flame retardant (ikizamini cyo gutwika vertical)

Nyuma yo gutwika umurongo wa santimetero 12 munsi yumuriro wa propane kumasegonda 12, kura urumuri hanyuma upime igihe cyakurikiyeho, igihe cyo gucana umuriro, hamwe nuburebure bwa char.

(2) Imikorere yo Kurinda Ubushyuhe (TPP)

①Ikizamini cyo gukingira ubushyuhe (TPP): shyira umwenda munsi yubushyuhe bwo gukwirakwiza ubushyuhe hamwe nimirasire yubushyuhe, hanyuma wandike igihe gikenewe cyo gutwikwa murwego rwa kabiri.

Ubushyuhe bwigihe X ubushyuhe isoko = agaciro ka TPP

②Uburyo bwo gupima TPP

Ikizamini cya TPP nugushira umwenda wa santimetero 6 munsi yumuriro hamwe nubushyuhe bwumuriro hamwe nimbaraga zose za 2cal / cm2.sec, hanyuma ukandika igihe gisabwa kugirango ugere kurwego rwa kabiri.Agaciro ka TPP nigihe cyikubye na cal / cm2.Agaciro ka sec.Bitandukanye nikizamini cyo gutwika gihagaritse, ikizamini cya TPP kirashobora kutubwira imbaraga zigomba gukoreshwa muguhuza uruhu rwabantu binyuze mumyenda itandukanye kugirango tugere ku rwego rwa kabiri.Nukuvuga ko, agaciro ka TPP hejuru, umwenda wangiza umubiri cyane iyo uhuye nubushyuhe bwinshi numuriro mwinshi.Mubihe, urwego rwo hejuru kurinda, urwego TPP agaciro nirwo ruhuza rutaziguye kumikorere yo gukingira ubushyuhe.

③Ikizamini cyo kurinda ubushyuhe bwa Thermo-man (Thermo-man?)

Kugirango turusheho kwigana urugero rwo gutwika umubiri wumuntu mumuriro nyirizina, bikoreshwa mugupima urugero rwuburinzi ikositimu yose ishobora gutanga mugihe cyumuriro nyirizina.Duhereye kuri iki kizamini, turashobora guhanura urwego rwa kabiri nuwa gatatu rwaka ku mubiri, uko urwego rwo gutwika umubiri wose, niko amahirwe menshi yo kubaho.

Ikizamini cyikitegererezo cyumubiri wumuntu nugushira icyitegererezo cyumubiri wa santimetero 6 zakozwe mubirahuri bidasanzwe bya epoxy resin hamwe na 122 bipima ubushyuhe kumubiri wose, ugashyiraho ikositimu idacana umuriro, ukabishyira kuri 2cal / Muri cm2.sec ubushyuhe, mudasobwa igereranya urwego n’ahantu ho gutwika icyiciro cya kabiri nicyiciro cya gatatu gishobora kwibasirwa nuruhu rwabantu rushingiye kumibare yakusanyijwe mubipimo 122 bipima ubushyuhe.

Imikorere yo kurinda

1) Ifite umurimo uhoraho wo kurinda;

2) Ifite umurimo wo kudashonga no kudashyigikira gutwikwa;

3) Ifite umurimo wo kutavunika;

4) Igikorwa cyo kurwanya ruswa;

5) Kuramba kandi birwanya kwambara;

6) Ihumure.

Imiterere n'ibikoresho by'imyenda yo kurwana yo mu 1997

(1) Imiterere yimyambaro yintambara yo mu 1997

Imyambaro yo kurwana yo mu 1997 igizwe n'ikote ryo hejuru hamwe n'ipantaro, naho ikote ryo hejuru hamwe n'ipantaro byose bigizwe n'ibice bine, aribyo: hejuru y'ubutaka, igicanwa kitarimo amazi, icyuma gishyuha n'ubushyuhe.

Igice cyo hanze: Ikozwe mu bikoresho bya Metas yakozwe na Sosiyete y'Abanyamerika DuPont, irimo 5% ya fibre ya Kevlar, irwanya ubushyuhe bwo hejuru bwa 4720C, ikomeza gucana umuriro, ibikoresho ntibigabanuka iyo ihuye n’umuriro, kandi ntibitanga ibitonyanga bishonga.

Igice kitarimo amazi: PTFE idafite amazi na diaphragm yumuyaga.

Igikoresho cyo kubika: Flame-retardant chimique fibre idakozwe.

Ihumure: igitambaro cyiza cya pamba, ubwoya.

(2) Ibikoresho by'imyenda yo kurwana yo mu 1997

Flame -kudoda imyenda

Imyenda yo kurwanya umuriro muri rusange ikoreshwa mubitambara bya flame retardant.Ibihugu byinshi mumahanga nka Amerika, Ubufaransa, Ubuyapani, Ubwongereza nibindi bihugu bikoresha impumuro nziza ya polyamide fibre (imyenda ya Nomax fibrous).Iyi myenda ifite imikorere myiza ya flame retardant, imbaraga nyinshi, ihindagurika ryinshi ryumuriro.Uburozi bwa rusange bwo gutwika buri hasi cyane kandi bufite urugero runini rwa aside -alkali.

Ome Nomex (Nomex) ni ituze ryiza ryumuriro muri Dupont yo muri Amerika Dupont.Ntabwo ishonga kuri dogere 377, ariko izabora.Nocos III ni uruvange rwa 95% ya fibre ya Fangfang polyamide hamwe na 5% cyane -kuba cyane kuri fibre ya Fangcanamide, ishobora gukora imyenda ikomeye cyane, ishobora guhagarika ibintu byinshi bya chimique na acide.Ikindi gicuruzwa gikunze gukoreshwa ku isoko rya Aziya, ni 75% ya Nomex, 23% bivanze na Fang Fang, na 2% fibre ya karubone.

Kermel ni Ubufaransa.Kmmier ikozwe muri acide polytic-aminoly.Kuberako ubuso bwa fibre ya Kichlk yoroshye kandi kwambukiranya hafi kuzenguruka, ibyiyumvo byayo byoroshye kuruta ibindi bitambaro bya polyamine.Kmmier irashobora kandi guhagarika imiti, kandi ifite imbaraga zo kurwanya -abrasion.Ubushyuhe bwumuriro buri munsi yizindi myenda ikozwe na fibre polyamide ya Fang, ishobora kwihanganira ubushyuhe bwinshi bwa dogere 250 mugihe kirekire.

Ano Kanox {Tayiwani} ni fibre pre -oxidation, iboneka hamwe na karuboni ituzuye ya fibre polypropilene (ibi birashobora gutuma fibre irwanya fibre).Ibyuma bishobora guhagarika imiti, imishwarara yumuriro no gushonga, kandi bifite ubushyuhe bwiza.Polypropilene ya karubone ibora kuri dogere 300, ariko mubisanzwe izasenyuka mugihe ubushyuhe bugeze kuri dogere 550.Imyenda ikingira ikozwe mu mwenda wa polypropilene irashobora kugaragara ku bushyuhe bwinshi mugihe gito.

④NOMEX @ ubushyuhe -burwanya flame retardant fibre: amazina yimiti muri aroma -fragrance polyamide fibre, urugo rwitwa aramid 1313 fibre.

⑤KKEVLAR @ -Ubucucike Buke bwagutse bwamasasu Ke: Izina ryimiti ni igice cya fibre ya aromatic polyamide, naho murugo bita aramid 1414 fibre.

⑥P-140 fibre: fibre karubone ipfunyitse muri nylon

⑦Polymer yibikoresho: compte microporous tetrafluoroethylene

Abashinzwe kuzimya umuriro ni umwe mu mirimo ifitanye isano rya bugufi kuri iyi si, kandi akenshi ituma adukoraho urupfu.Imbere yo gushyigikirwa mu mwuka biteye akaga, byaturutse ku kubaha ubuzima.
