Ngesikhathi sokubunjwa komjovo weglasi le-fiber fiber eliqinisiwe, ukusebenza komshini ngamunye kujwayelekile, kepha umkhiqizo unezinkinga zekhwalithi ebonakalayo, futhi amamaki amhlophe asabalalayo akhiqizwa ngaphezulu, futhi lolu phawu olumhlophe luthanda ukuba lubi ngokwanda ingilazi fiber okuqukethwe. Lo mkhuba waziwa kakhulu ngokuthi "i-fiber ezintantayo", engamukeleki ezingxenyeni zepulasitiki ezinezidingo zokubukeka okuphezulu.
Ukuhlaziywa Kwembangela
Isimo se "fiber esintantayo" sibangelwa ukuvezwa kwengilazi yefayibha. I-fiber emhlophe yengilazi ivezwa ebusweni ngesikhathi senqubo yokugcwalisa nokuncibilika kwepulasitiki. Ngemuva kokubumbana, kuzokwakha amamaki amhlophe asabalalayo ebusweni bengxenye yepulasitiki. Lapho ingxenye yepulasitiki imnyama Lapho umehluko wombala ukwanda, kuba sobala ngokwengeziwe.
Izizathu eziyinhloko zokwakheka kwawo zimi kanje:
1. Ngenkathi yokugeleza kokuncibilika kwepulasitiki, ngenxa yomehluko woketshezi nobuningi phakathi kwengilazi nefayibha, bobabili banomkhuba wokwehlukana. Intambo yengilazi yesibalo esiphansi intanta phezulu, bese i-resin ejiyile icwila kuyo. , Ngakho-ke kwakhiwa into evezwa ngengilazi yefibre;
2. Ngoba ukuncibilika kwepulasitiki kufakwa kumandla wokushayisana nokugunda kwesikulufu, umlomo wombhobho, umgijimi kanye nesango ngesikhathi senqubo yokugeleza, kuzodala umehluko ku-viscosity yendawo, futhi ngasikhathi sinye, kuzobhubhisa ungqimba lwesixhumi esibonakalayo ku ubuso befayibha yengilazi, ne-viscosity encibilikayo izoba ncane. , Uma umonakalo ulingene kakhulu ungqimba lwesixhumi esibonakalayo, okuba kuncane amandla okubopha phakathi kwefayibha yengilazi ne-resin. Lapho amandla okuhlanganisa emancane ukuya ezingeni elithile, i-fiber fiber izokhipha ubugqila be-matrix ye-resin futhi kancane kancane iqoqele phezulu futhi iveze obala;
3. Lapho ukuncibilika kwepulasitiki kufakwa emgodini, kuzokwakha umphumela "womthombo", okungukuthi, i-fiber fiber izohamba isuka ngaphakathi iye ngaphandle futhi ixhumane nobuso bomgodi. Ngoba izinga lokushisa lesikhunta liphansi, i-fiber yengilazi ilula futhi iyajiya ngokushesha. Iba yiqhwa khona manjalo, futhi uma ingeke izungezwe ngokuphelele ukuncibilika ngesikhathi, izovezwa bese yakha "imicu entantayo".
Ngakho-ke, ukwakheka komkhuba "wentambo entantayo" akuhlobene kuphela nokwakheka nezici zezinto zokwakha zepulasitiki, kepha futhi kuhlobene nenqubo yokubumba, enenkinga enkulu nokungaqiniseki.
Masikhulume ngokuthi ungayithuthukisa kanjani into "yefayibha elintantayo" ngokombono wefomula nenqubo.
Ukusebenziseka kwefomula
