Impuphu Yefayibha YengilaziAkuyona nje into yokugcwalisa; iqina ngokuhlangana ngokomzimba ezingeni elincane. Ngemva kokuncibilika nokukhipha ekushiseni okuphezulu kanye nokugaya okulandelayo ekushiseni okuphansi, i-fiber yengilazi engena-alkali (E-glass) isagcina isilinganiso esiphezulu futhi ayisebenzi ebusweni. Inemiphetho eqinile, kodwa ayisebenzi futhi ikhiqiza inethiwekhi yokusekela kuma-matrices e-resin noma esimende noma e-mortar. Ukusatshalaliswa kosayizi wezinhlayiya ze-mesh engu-150 kuya ku-mesh engu-400 kunikeza ukuhweba phakathi kokuhlakazeka okulula kanye namandla okubambelela, okuqinile kakhulu kuzoholela ekuzinzeni futhi okuncane kakhulu kuzonciphisa umthwalo wokuthwala. Izicelo ezifaneleka kangcono ekumbozweni okucwebezelayo okuphezulu noma ekubhodweni okunembile yizinhlobo ezinhle kakhulu, njenge-fiber yengilazi engu-1250.
Ukuthuthukiswa okuphawulekayo kobulukhuni be-substrate kanye nokumelana nokuguguleka yi-glass powder kuvela ezicini zayo ze-physicochemical kanye nezindlela ezincane ngaphakathi kwezinhlelo zezinto. Lokhu kuqina kwenzeka ikakhulukazi ngezindlela ezimbili: "ukuqinisa ukugcwalisa ngokomzimba" kanye "nokuthuthukisa ukubopha kwe-interface," ngezimiso ezilandelayo ezithile:
Umphumela Wokugcwalisa Ongokoqobo Ngokuqina Okuphezulu Kwangaphakathi
Impuphu yengilazi ngokuyinhloko yakhiwe ngamakhemikhali angaphili njenge-silica nama-borate. Ngemva kokuncibilika nokupholisa okushisa okuphezulu, yakha izinhlayiya ezi-amorphous ezinobunzima be-Mohs obungu-6-7, obudlula kakhulu obezinto eziyisisekelo ezifana nepulasitiki, ama-resin, kanye nokumbozwa okuvamile (ngokuvamile okungu-2-4). Uma ihlakazeka ngokulinganayo ngaphakathi kwe-matrix,ingilazi yempuphuifaka "izinhlayiya ezincane eziqinile" ezingenakubalwa kuyo yonke into:
La maphuzu aqinile athwala ngqo ingcindezi yangaphandle kanye nokungqubuzana, anciphisa ukucindezeleka kanye nokuguguleka kwesisekelo sezinto ngokwazo, esebenza “njengohlaka olumelana nokuguguleka”;
Ukuba khona kwamaphuzu aqinile kuvimbela ukuguquka kwepulasitiki ebusweni bezinto ezibonakalayo. Lapho into yangaphandle iklwebheka ebusweni, izinhlayiya zempuphu yengilazi ziyamelana nokwakheka kokuklwebheka, ngaleyo ndlela zithuthukise ubulukhuni kanye nokumelana nokuklwebheka.
Isakhiwo Esiqinile Sinciphisa Izindlela Zokuguguleka
Izinhlayiya zempuphu yengilazi zinezilinganiso ezincane (ngokuvamile isikali se-micrometer kuya ku-nanometer) kanye nokuhlakazeka okuhle kakhulu, zigcwalisa ngokulinganayo izikhala ezincane kakhulu ezintweni ze-matrix ukuze zakhe isakhiwo esihlanganisiwe esiminyene:
Ngesikhathi sokuncibilika noma ukupholisa, ingilazi yempuphu yakha isigaba esiqhubekayo ne-matrix, isusa izikhala ezihlanganayo futhi inciphise ukuguguleka kwendawo okubangelwa ukugxila kokucindezeleka. Lokhu kuphumela endaweni efanayo futhi engagugi.
Ukubopha phakathi kobuso kuthuthukisa ukusebenza kahle kokudlulisa umthwalo
Impuphu yengilazi ibonisa ukuhambisana okuhle kakhulu nezinto ze-matrix ezifana nama-resin namapulasitiki. Amanye amampuphu engilazi aguqulwe ubuso angahlangana ngamakhemikhali ne-matrix, akhe ukuxhumana okuqinile kwe-interfacial.
Ukuqina kwamakhemikhali kumelana nokugqwala kwemvelo
Impuphu yengilaziIbonisa ukungangeni kahle kwamakhemikhali, imelana nama-acid, ama-alkali, ukubola, kanye nokuguga. Igcina ukusebenza okuzinzile ezindaweni eziyinkimbinkimbi (isb., ngaphandle, ezindaweni zamakhemikhali):
Kuvimbela umonakalo wesakhiwo somphezulu obangelwa ukugqwala kwamakhemikhali, kulondoloza ubulukhuni kanye nokumelana nokuguguleka;
Ikakhulukazi ezimbozweni nase-inki, ukumelana kwempuphu yengilazi ye-UV kanye nokumelana nokuguga okunomswakama nokushisa kuyalibazisa ukuwohloka kwe-matrix, okwandisa isikhathi sokuguguleka kwezinto.
