Ingabe i-ABS ilusizo ngempela ipeni lokufunda lezingane?
Siba nesikhathi sokuchitha nezingane ngesikhathi samaholide, futhi ukufunda nezingane ngepeni lokufunda nakho kuwumqondo omuhle.Abantu abadala kufanele baqondise izingane ngendlela efanele ukuze zichaze izindawo lapho ipeni lokufunda likhomba khona encwadini, futhi babuze ngokufanelekile izingane ngolwazi olusencwadini, okunomthelela omuhle ekuthuthukiseni inkumbulo yengqondo yezingane zamaphuzu olwazi encwadini.
Ngakho-ke, ipeni lokufunda selibe umsizi omuhle wezingane ekufundeni.Ngenxa yokuthi isetshenziswa kaningi, abazali abaningi bakhathazeke kakhulu ngokuphepha kwezinto ezisetshenziswa ipeni lokufunda.Sithole ukuthi iningi lamapeni okufunda manje asebenzisa izinto zokulwa nokuwa ze-ABS ezivumelana nemvelo njengezo ezijwayelekile.Nakuba le nto ivame kakhulu ekuphileni kwethu kwansuku zonke, asazi noma ilungele ukusetshenziswa kwezingane isikhathi eside.
I-ABS resin ingenye yezinhlaka ezinhlanu ezinkulu zokwenziwa.Inokumelana nomthelela omuhle kakhulu, ukumelana nokushisa, ukumelana nokushisa okuphansi, ukumelana namakhemikhali kanye nezakhiwo zikagesi.Iphinde ibe nezici zokucubungula kalula, ubukhulu bomkhiqizo obuzinzile, nesicwebezelisi esihle.Kulula ukuyipenda., umbala, ngakho-ke kuhle ukusebenzisa i-abs yezinto zokufunda zepeni zezingane?
I-ABS iyi-polymer ephezulu.Lezi zinto azinabo ubuthi, kepha ezinye izithasiselo zengezwa ngesikhathi sokuhlanganiswa, ukucubungula kanye nobunjiniyela.Lezi zithako zingama-molecule amancane angamuncwa umzimba, okungumthombo walokho okubizwa ngokuthi ubuthi.I-PC, i-PE/ABS nezinye izinto zinhle uma kuqhathaniswa, kuyilapho i-PVC ingenabo ubuthi obuncane.Kunconywa ukukhetha ipeni lokufunda lezingane elihlangabezana nezindinganiso zaseYurophu zokuthula kwengqondo lapho ulisebenzisa.Lapho ingane isencane, maningi amathuba okuba uthenge uhlobo olukhulu lwamapeni okufunda ezingane.Njengoba isisho sisho, ezishibhile azilungile, futhi okuhle akushibhile.Intengo yamapeni okufunda ezingane isengachaza ezinye zezinkinga.
Eqinisweni, iningi lamapulasitiki alinawo umthelela wobuthi obuqondile ezintweni eziphilayo ngoba azinzile ngokwemvelo futhi awahlangani nezinye izinto ezisezingeni lokushisa elivamile.
Yiqiniso, izithasiselo ezahlukene zengezwa kumapulasitiki ngenxa yezinhlelo zokusebenza ezahlukene, kodwa le pulasitiki ehlukile ihluke kakhulu.Izithasiselo zepulasitiki ngokuvamile zihlanganisa izigcwalisi ezingaphili, imicu yengilazi, izimibalabala, ama-antioxidants, ama-anti-ultraviolet, ama-plasticizers, nokunye okunjalo.Ama-inorganic fillers namafibre engilazi angamaminerali nengilazi anezakhiwo ezinzile futhi awanabo ubuthi emzimbeni womuntu.Umthamo we-antioxidant ne-anti-ultraviolet ejenti ngokuvamile mncane, kodwa umthamo we-1-2 ‰ yiqiniso awunabo ubuthi noma ubuthi obuphansi.Ipulasitiki okungenzeka ibe yingozi kakhulu kubantu i-PVC.Okuqukethwe okungeziwe kwepulasitiki kungase kufinyelele ku-60-70%, okunzima ukuqinisekisa ukuthi ngeke kube yingozi emzimbeni womuntu.
Amapulasitiki e-ABS asetshenziswa kakhulu ezintweni zasendlini, njengeziqandisi, imishini yokuwasha, ama-air conditioner, ama-oven microwave, njll., esiyibiza ngempahla emhlophe.Ipulasitiki ngokuvamile isebenzisa izithasiselo ezincane, futhi i-ABS resin toner ehlanzekile isetshenziswa kakhulu.Ngokwezinga lamanje lemboni yepulasitiki, iningi lama-toner yimikhiqizo enobungani bemvelo, engeke ithinte umzimba womuntu kanye nemvelo.Ngakho-ke ungakhathazeki ngakho, vele uyisebenzise ngokuthula kwengqondo.

Ekwakhiweni kwamapeni okufunda ezingane, ukuphepha kubaluleke kakhulu, hhayi izinto ezibonakalayo kuphela, kodwa futhi nezidingo zokuphepha njengokuklanywa kwamapeni okufunda ezingane ezifundisayo.Isibonelo, ukwakheka komklamo kungabangela ukulimala, futhi ingxenye ekhishwayo izobangela ingane ukuba igwinye ngephutha, konke lokhu ukucatshangelwa kokuphepha.Ekwakhiweni kwamapeni okufunda ezingane, ukugqugquzelwa komklamo ohambisana nemvelo nophephile akusizi nje kuphela ukusetshenziswa kwezingane, kodwa futhi kunomthelela ekuthuthukisweni okunempilo kwemakethe yepeni yokufunda yezingane yezwe lami.
