Uruganda rwimyenda yumuriro rutarwanya - imyenda

Umwenda wanze fibre yabanjirije okiside hamwe nubushyuhe buhebuje bwo guhangana nubushyuhe bwo hejuru hamwe na aramide ifite imbaraga nyinshi zidasanzwe, ifumbire mvaruganda, ubushyuhe bwo hejuru hamwe no kwihanganira kwambara, bivanze ukurikije igipimo runaka. Nutsinde ibibi byiyi fibre ebyiri. Ibyiza bya fibre byombi bizanwa mubikorwa.

 

Icyiciro cya Flame retardant: Ingorabahizi yiki cyerekezo ni ukuzunguruka mbere ya ogisijeni ya silike na aramide. Flame-retardant ibintu byimyambaro yimyenda yumuriro nyuma yo gushyira mubikorwa byinshi, iboneza nikoranabuhanga byahinduwe cyane, kuburyo igipimo cyizunguruka nubwiza bwimyenda byazamutse cyane, kuzungurukauruganda rwimpapuroigipimo cyageze hejuru ya 80%. Nyuma yingufu zingirakamaro zibishinzwe ishyirahamwe, ibipimo byimyenda bigeze kubisabwa bisanzwe, birashobora gukorwa mubushyuhe bwo hejuru, ubushyuhe bwumuriro, imyenda irinda umuriro. Igitambara ntigifite imbaraga zidasanzwe gusa, kwihanganira kwambara, hamwe no kutagira umuriro mwiza, kurwanya ubushyuhe bwinshi, kurwanya imishwarara yumuriro, mugihe cyose agaciro k’ibicuruzwa biva mu bwoko bumwe bwa 1113, hari amahirwe menshi yo gukora. Iyi myenda yerekanwe nabakoresha kuganza mubyukuri, mubidukikije byimyenda irinda UV, imirasire yubushyuhe bwo hejuru, ubushyuhe bwo hejuru bwo gushonga, gutwika umuriro nibindi. Imyenda ifite ubushyuhe bwinshi, irwanya ubushyuhe, flame retardant multifunctional compitifitifike yimyenda ni nziza, imbaraga nyinshi nimbaraga zihoraho zigabanuka gake.uruganda rwimpapuro

2 Ikoreshwa rya flame retardant hamwe na retardant imyenda imyenda ifasha ibyiciro: ubwoko butandukanye bwa flame retardant, uburyo bwo gutondekanya nabwo butandukanye. Ukurikije ibintu bya flame retardant, birashobora kugabanywa muri halogenated flame retardant, fosifore flame retardant, azote flame retardant, nibindi. Ukurikije ikoreshwa rya flame retardant na polymer muburyo, bigabanijwe kongeramo ubwoko nubwoko bwa reaction; Ukurikije uburebure bwimyenda ya flame retardant, irashobora kugabanwa muburyo butatu: flame retardant fining agent, idashobora kuramba flame retardant finans agent na agent flame retardant finans agent. Ukurikije ubwoko bwimvange irashobora kugabanywamo inorganic flame retardant na organic flame retardant. Ibikurikira byerekana cyane imyenda yakazi ya flame retardant yashyizwe muburyo bubiri bwa nyuma.

1.1 Gutondekanya ukurikije igihe kirekireuruganda rwimpapuro

1. Flame retardant ishonga mumazi, kandi umwenda urashobora gukoreshwa nyuma yo kwibira no gukama. Hariho kandi ubwogero bubiri, ubwogero bwa kabiri hamwe na ammonia cyangwa ivu rya soda, kuburyo oxyde yashyizwe kumyenda. Ubu buryo buroroshye kandi buhendutse, ariko kumva imyenda irakennye, kandi ingaruka zo gucana umuriro ziragabanuka cyane nyuma yo gukaraba. Bikunze gukoreshwa mumyenda ikingira.

. Uburyo bukubiyemo uburyo bwa acide urea fosifori (bakunze kwita uburyo bwa Banflam), uburyo bwa fosifate yinkari, ammonium fosifate - methyl acetate ivanze nuburyo bwo gukemura.

. Uburyo nyamukuru burimo uburyo bwa Ciba (CP) nuburyo bwa Proban. CP inzira yakozwe na Ciba Company, Ubusuwisi. Inzira iroroshye kuyishyira mubikorwa kandi ingaruka ya flame-retardant iratangaje. Ikibi nuko gutakaza imbaraga zumwenda ari binini kandi ingaruka kumikorere yimyenda nini. Uburyo bwa Proban bwakozwe nabongereza Aubry Wilson Co, LTD., Ubu buryo bwarangije umwenda, ingaruka za flame retardant nibyiza, cyane cyane nyuma yo kuvura imyenda ukumva no kuyifata neza ntagereranywa nubundi buryo bwo kurangiza, ariko ubu buryo ni bubi, umwanda ukabije w’ibidukikije, bityo kuzamura ni bike.

2.2 Itondekanya rya flame retardants kubwoko bwimvange

. , zirconi, zirconi, nibindi, hamwe na hydroxide ya aluminium, hydroxide ya magnesium, fosifore itukura, okiside ya antimoni niyo ikoreshwa cyane, cyane cyane hydroxide ya aluminium, hydroxide ya magnesium ntishobora gukinisha gusa umuriro, ariko kandi irashobora gukina Kugira ngo yuzuze ibikorwa. Bafite ibintu biranga ubushyuhe bwiza, gukora neza, guhagarika umwotsi, kurwanya ibitonyanga, kuzuza neza, mubyukuri nta kwanduza ibidukikije nigiciro gihenze, nibindi, kandi byakoreshejwe cyane mubikoresho bitarinda umuriro wa halogene. Ariko inorganic flame retardant fire retardant imyenda yo gukaraba birwanya ubukene, ibi biterwa nuko retorganant flame retardant ifite polarite ikomeye na hydrophilicity, kandi guhuza imyenda idafite polar ni bibi. Muri icyo gihe, kugira ngo huzuzwe ibisabwa byateganijwe kugira ngo flame retardant isabwa, imiti igabanya ubukana yongeweho ku bwinshi, igira ingaruka zikomeye ku miterere y’imashini no gutunganya ibikoresho. Kubwibyo, mumyaka yashize, ubushakashatsi kuri superrefinement na nanisation ya gakondo ya organic organique flame retardants yitabweho bitigeze bibaho. Byongeye kandi, kugirango ugabanye urugero rwa flame retardant hamwe ningaruka zimwe za retardant, ni nubuyobozi bwubushakashatsi bwa flame retardant mumyaka yashize kugirango ihuze flame retardant kandi yige ningaruka ziterwa na flame retardant.

. Iyambere ni mike cyane mugukoresha. Halogenated flame retardants harimo chlorine na bromine. Nyamara, ingaruka ziterwa na chlorine flame retardants ni mbi cyane kurenza bromine flame retardants, kuko ntibyoroshye kubyara itsinda rya chlorine kubuntu. Imyenda irwanya inkari kandi idacuma, wongeyeho, kubera kwangirika nuburozi bwa bromide nyuma yo kubora kwinshi ni ntoya, kubwibyo gukoresha bike birashobora kugera ku ngaruka mbi ya flame nka chloride. Bromined flame retardants irasanzwe cyane. Nyamara, duhereye ku mikoreshereze rusange, kubera amakosa ya retogenants ya halogenated flame retardants, irimo aside ya halogene mu bicuruzwa byabo byangirika, umwotsi munini kandi byangiza umubiri w’umuntu, bigenda bisimburwa buhoro buhoro n’ibindi bikoresho bitagira umuriro n’umwenda utagira umuriro. inyongera.
