1. Iyini i-fiber yengilazi?
Imicu yengilazizisetshenziswa kabanzi ngenxa yokuthi zisebenza kahle ezindleko kanye nezakhiwo ezinhle, ikakhulukazi embonini yezinhlanganisela. Ngasekuqaleni kwekhulu le-18, abaseYurophu baqaphela ukuthi ingilazi ingaphothwa ibe yimicu yokuluka. Ibhokisi lombusi waseFrance uNapoleon lase livele linezindwangu zokuhlobisa ezenziwei-fiberglassImicu yengilazi inemicu kanye nemicu emifushane noma ama-floc. Imicu yengilazi ivame ukusetshenziswa ezintweni ezihlanganisiwe, imikhiqizo yerabha, amabhande okuhambisa, ama-tarpaulin, njll. Imicu emifushane isetshenziswa kakhulu kuma-felt angalukiwe, amapulasitiki obunjiniyela kanye nezinto ezihlanganisiwe.
Izakhiwo ezikhangayo zomzimba nezemishini ze-glass fiber, ukulula kokukhiqizwa, kanye nezindleko eziphansi uma kuqhathaniswai-carbon fiberkwenze kube yinto ekhethwayo yokusetshenziswa kwenhlanganisela esebenza kahle kakhulu. Imicu yengilazi yakhiwe ngama-oxide e-silica. Imicu yengilazi inezakhiwo ezinhle kakhulu zokwenza izinto njengokuba buthakathaka kakhulu, amandla aphezulu, ukuqina okuphansi kanye nesisindo esincane.
Ama-polymer aqiniswe ngefayibha yengilazi aqukethe uhlobo olukhulu lwezinhlobo ezahlukene zefayibha yengilazi, njengefayibha ende, imicu eqoshiwe, omata abalukiwe, kanyeomata abaqoshiwe, futhi zisetshenziselwa ukuthuthukisa izakhiwo zemishini neze-tribological ze-polymer composites. Imicu yengilazi ingafinyelela izilinganiso eziphezulu zokuqala, kodwa ukuphuka kungabangela ukuthi imicu iphuke ngesikhathi sokucubungula.
1. izici zefayibha yengilazi
Izici eziyinhloko ze-glass fiber zifaka phakathi izici ezilandelayo:
Akulula ukumunca amanzi:I-fiber yengilazi iyaxosha amanzi futhi ayifaneleki izingubo, ngoba umjuluko ngeke umunceke, okwenza umuntu ogqokile azizwe emanzi; ngoba indwangu ayithinteki ngamanzi, ngeke inciphe
Ukunganwebeki:Ngenxa yokuntuleka kokunwebeka, indwangu ayinakunwebeka nokululama okungokwemvelo. Ngakho-ke, zidinga ukwelashwa kobuso ukuze zimelane nokushwabana.
Amandla Aphezulu:I-fiberglass inamandla kakhulu, cishe iqine njenge-Kevlar. Kodwa-ke, lapho imicu ikhuhlana, iyaphuka futhi ibangele ukuthi indwangu ibonakale ingcolile.
Ukuvikela:Ngamafuphi, i-fiberglass iyisivikelo esihle kakhulu.
Ukudonseka:Imicu igoqeka kahle, okwenza ifaneleke kakhulu kumakhethini.
Ukumelana Nokushisa:Imicu yengilazi inokumelana nokushisa okuphezulu, ingamelana namazinga okushisa afinyelela ku-315°C, ayithinteki ukukhanya kwelanga, i-bleach, amagciwane, isikhunta, izinambuzane noma ama-alkali.
Okungathinteka:Imicu yengilazi ithintwa yi-hydrofluoric acid kanye ne-hot phosphoric acid. Njengoba i-fiber iwumkhiqizo osekelwe engilazini, eminye imicu yengilazi eluhlaza kufanele iphathwe ngokucophelela, njengezinto zokuvikela zasekhaya, ngoba iziphetho ze-fiber zibuthakathaka futhi zingabhoboza isikhumba, ngakho-ke amagilavu kufanele agqokwe lapho kuphathwa i-fiberglass.
3. Inqubo yokukhiqiza i-glass fiber
I-fiber yengilaziiyi-fiber engeyona insimbi esetshenziswa kabanzi njengamanje njengezinto zezimboni. Ngokuvamile, izinto eziyisisekelo zokusetshenziswa kwe-fiber yengilazi zifaka amaminerali ahlukahlukene emvelo namakhemikhali enziwe ngabantu, izingxenye eziyinhloko isihlabathi se-silica, i-limestone kanye nomlotha we-soda.
Isihlabathi se-silica sisebenza njengengilazi, kuyilapho umlotha we-soda kanye ne-limestone kusiza ekwehliseni izinga lokushisa elincibilikayo. I-coefficient ephansi yokwanda kokushisa kuhlanganiswe nokushisa okuphansi uma kuqhathaniswa ne-asbestos kanye nemicu ye-organic kwenza i-fiberglass ibe yinto eqinile ngokwesilinganiso eqeda ukushisa ngokushesha.
Imicu yengilazikukhiqizwa ngokuncibilika okuqondile, okubandakanya izinqubo ezifana nokuhlanganisa, ukuncibilika, ukuphotha, ukumboza, ukomisa, kanye nokupakisha. Iqoqo liyisimo sokuqala sokukhiqizwa kwengilazi, lapho inani lezinto lixutshwa kahle khona bese ingxube ithunyelwa esithandweni ukuze incibilike ekushiseni okuphezulu okungu-1400°C. Leli zinga lokushisa lanele ukuguqula isihlabathi nezinye izithako zibe yisimo esincibilikisiwe; ingilazi encibilikisiwe bese igeleza iye kumshini wokuhlanza bese izinga lokushisa lehla liye ku-1370°C.
Ngesikhathi kuphothwa imicu yengilazi, ingilazi encibilikisiwe iphuma ngesikhwama esinezimbobo ezincane kakhulu. Ipuleti le-liner liyashiswa ngogesi futhi izinga lokushisa lalo lilawulwa ukuze kulondolozwe i-viscosity engaguquki. Kusetshenziswe i-water jet ukupholisa i-filament njengoba iphuma esikhwameni ekushiseni okungaba ngu-1204°C.
Umfudlana wengilazi encibilikisiwe okhishwayo udonswa ngomshini ube yizicucu ezinobubanzi obusukela ku-4 μm kuya ku-34 μm. Ukucindezeleka kunikezwa kusetshenziswa umshini wokujikisa osheshayo bese ingilazi encibilikisiwe idonswa ibe yizicucu. Esigabeni sokugcina, kufakwa upende wamakhemikhali wezithambisi, izihlanganisi kanye nama-coupling agents kuma-filaments. Ukugcoba kusiza ukuvikela izicucu ekukhubekeni njengoba ziqoqwa futhi ziboshwe zibe amaphakheji. Ngemva kokulinganisa, izicucu zomiswa kuhhavini; izicucu zibe sezilungele ukucutshungulwa okwengeziwe zibe yizicucu, izicucu noma izicucu eziqoshiwe.
4.ukusetshenziswa kwefayibha yengilazi
I-fiberglass kuyinto engaphili engashi futhi egcina cishe u-25% wamandla ayo okuqala ku-540°C. Amakhemikhali amaningi awathinti kakhulu imicu yengilazi. I-fiberglass engaphili ngeke ibune noma yonakale. Imicu yengilazi ithintwa yi-hydrofluoric acid, i-hot phosphoric acid kanye nezinto ezinamandla ze-alkaline.
Kuyinto enhle kakhulu yokuvikela ugesi.Izindwangu ze-fiberglasszinezakhiwo ezifana nokumuncwa komswakama okuphansi, amandla aphezulu, ukumelana nokushisa kanye nokungaguquguquki kwe-dielectric okuphansi, okwenza zibe yiziqinisi ezifanele kakhulu zamabhodi wesekethe aphrintiwe kanye nama-varnish avikelayo.
Isilinganiso samandla aphezulu kuya kwesisindo se-fiberglass senza kube yinto enhle kakhulu yezinhlelo zokusebenza ezidinga amandla aphezulu kanye nesisindo esincane. Uma isesimweni sendwangu, la mandla angaba ngawahlangothi olulodwa noma amabili, okuvumela ukuguquguquka ekwakhiweni kanye nezindleko zezinhlelo zokusebenza ezahlukahlukene emakethe yezimoto, ukwakhiwa kwezakhiwo, izimpahla zemidlalo, izindiza, ezolwandle, i-elekthronikhi, amandla asekhaya nawomoya.
Zisetshenziswa futhi ekwenziweni kwezinhlanganisela zesakhiwo, amabhodi wesekethe aphrintiwe kanye nemikhiqizo ehlukahlukene yezinhloso ezikhethekile. Ukukhiqizwa kwefayibha yengilazi yaminyaka yonke emhlabeni kungaba ngamathani ayizigidi ezingu-4.5, kanti abakhiqizi abayinhloko yiShayina (isabelo semakethe esingu-60%), i-United States kanye ne-European Union.
