izindaba

Ukubhekana nenkinga ekhulayo yokungcoliswa kwemvelo, ukuqwashisa ngokuvikelwa kwemvelo komphakathi kuye kwanda kancane kancane, futhi umkhuba wokusebenzisa izinto zemvelo nawo usukhulile. Imvelo enobungani, engasindi, ukusetshenziswa kwamandla okuphansi kanye nezici ezivuselelekayo zemicu yezitshalo kudonse ukunaka okukhulu. Kuzonqunywa esikhathini esizayo esibonakalayo Kuzoba nezinga eliphezulu lentuthuko. Kodwa-ke, i-plant fiber iyimpahla ehlukahlukene enokwakheka nesakhiwo esiyinkimbinkimbi, futhi indawo yayo iqukethe amaqembu e-hydrophilic hydroxyl. Ukuhambisana ne-matrix kudinga ukwelashwa okukhethekile ukuze kuthuthukiswe izakhiwo zenhlanganisela. Imicu yezitshalo isetshenziselwa izinto ezihlanganisiwe, kodwa eziningi zazo zilinganiselwe emicu emifushane nemicu engapheli. Izakhiwo ezinhle kakhulu zasekuqaleni azizange zisetshenziswe ngokugcwele, futhi zisetshenziswa kuphela njengezigcwalisi. Uma singethula ubuchwepheshe bokuluka, yisixazululo esihle. Ama-preforms we-plant fiber alukiwe angahlinzeka ngezinketho zokusebenza ezengeziwe zezinto eziyinhlanganisela, kodwa okwamanje asetshenziswa kancane futhi afanele ukuqhubeka nokucwaninga nokuthuthukiswa. Uma singacabanga kabusha ngendlela evamile yokusebenzisa i-fiber, futhi sethule imiqondo yesimanje eyinhlanganisela yobuchwepheshe ukuze siyithuthukise, sithuthukise izinzuzo zokusetshenziswa futhi sithuthukise ukushiyeka okungokwemvelo, izokwazi ukunikeza imicu yezitshalo inani elisha nokusetshenziswa.

Imicu yezitshalo ibilokhu ingehlukaniseki empilweni yomuntu yansuku zonke. Ngenxa yezici zayo ezilula nezivuselelekayo, imicu yezitshalo isiyinto ebaluleke kakhulu empilweni yomuntu.Kodwa-ke, ngokuthuthuka kobuchwepheshe kanye nokukhula kwemboni ye-petrochemical, imicu eyenziwe umuntu kanye namapulasitiki kancane kancane ashintsha imicu yezitshalo njengezinto ezijwayelekile ngenxa yezinzuzo zobuchwepheshe bokukhiqiza obuthuthuke kakhulu, ukuhlukahluka kwemikhiqizo kanye nokuqina okuhle. Kodwa-ke, i-petroleum ayiyona insiza evuselelekayo, futhi izinkinga zokulahlwa kwemfucuza ezibangelwa ukulahlwa kwemikhiqizo enjalo kanye nenani elikhulu lokukhishwa kokungcola phakathi nenqubo yokukhiqiza kubangele abantu ukuba bacabange kabusha ukusebenziseka kwezinto. Ngaphansi komkhuba wokuvikelwa kwemvelo kanye nokusimama, imicu yezitshalo yemvelo isiphinde yanakwa. Eminyakeni yamuva nje, izinto eziyinhlanganisela ezisebenzisa imicu yezitshalo njengezinto zokuqinisa seziqalile ukunakwa.

I-fiber yezitshalo kanye nenhlanganisela

Isakhiwo esiyinhlanganisela singaklanywa ngenqubo yokukhiqiza. I-fiber ehlanganiswe ne-matrix inikeza isimo esiphelele nesiqondile sezinto ezibonakalayo, futhi ivikela i-fiber ekuwohlokeni ngenxa yethonya lemvelo, futhi isebenza njengebhuloho lokudlulisa ukucindezeleka phakathi kwezintambo; kuyilapho i-fiber ithwala iningi lamandla angaphandle nezakhiwo zayo ezinhle kakhulu zemishini futhi ingadlula Ukuhlelwa okuqondile kufeza imisebenzi ehlukene. Ngenxa yokuminyana okuphansi namandla ayo aphezulu, i-fiber yezitshalo ingathuthukisa izakhiwo zemishini futhi igcine ukuminyana okuphansi lapho yenziwa izinhlanganisela ze-FRP. Ngaphezu kwalokho, imicu yezitshalo ngokuvamile ihlanganisa amangqamuzana ezitshalo, futhi izimbobo nezikhala ezikuyo zingaletha izici ezinhle kakhulu zokuvikela ukushisa entweni. Ebusweni bamandla angaphandle (njengokudlidliza), nawo azuza ku-porosity yawo, okuvumela amandla ukuba ahlakazeke ngokushesha. Ngaphezu kwalokho, inqubo ephelele yokukhiqiza i-fiber yezitshalo ikhipha ukungcoliswa okuncane futhi isebenzisa amakhemikhali amancane, inezinga lokushisa eliphansi lokusebenza, inenzuzo yokusebenzisa amandla aphansi, futhi izinga lokugqoka kwemishini ngesikhathi sokucubungula nalo liphansi; ngaphezu kwalokho, i-plant fiber iyizici zemvelo Ezivuselelekayo, ukukhiqizwa okusimeme kungafinyelelwa ngaphansi kokuphathwa nokulawula okunengqondo. Ngosizo lobuchwepheshe besimanje, ukubola nokumelana nesimo sezulu kwezinto kulawulwa kahle, ukuze zikwazi ukubola ngemva komjikelezo wokuphila komkhiqizo, ngaphandle kokubangela ukunqwabelana kwemfucuza, kanye nekhabhoni ekhishwa ngokubola nayo itholakala ekukhuleni kokuqala. Umthombo wekhabhoni osemkhathini ungaba ne-carbon neutral.
