Ngaba imathiriyeli ye-ABS ilungile ngokwenene kwipeni yokufunda yabantwana?
Sinexesha lokulichitha nabantwana ngexesha leeholide, kwaye ukufunda nabantwana ngepeni yokufunda nako kungumbono olungileyo.Abantu abadala kufuneka babakhokele ngokufanelekileyo abantwana ekucaciseni iindawo apho usiba lokufunda lukhomba khona encwadini, kwaye ngokufanelekileyo babuze abantwana ngolwazi olusencwadini, nto leyo enefuthe elihle ekwandiseni inkumbulo yabantwana yengqondo yeengongoma zolwazi ezisencwadini.
Ngoko ke, ipeni yokufunda ibe ngumncedi olungileyo wokufunda wabantwana.Ngenxa yokuba isetyenziswa rhoqo, abazali abaninzi baxhalabele kakhulu ngokukhuseleka kwezinto ezisetyenziswa yipeni yokufunda.Siye safumanisa ukuba uninzi lweepeni zokufunda ngoku zisebenzisa i-ABS ekhusela imo yokusingqongileyo njengeyona nto iphambili.Nangona esi sixhobo sixhaphake kakhulu kubomi bethu bemihla ngemihla, asazi ukuba ngaba kufanelekile ukuba abantwana basebenzise ixesha elide.
I-ABS resin yenye yezona ntlanu ezinkulu zokwenziwa.Inokumelana nempembelelo ebalaseleyo, ukumelana nobushushu, ukumelana nobushushu obuphantsi, ukuxhathisa imichiza kunye neempawu zombane.Ikwanazo neempawu zokucutshungulwa lula, imilinganiselo yemveliso ezinzileyo, kunye neglosi entle yomphezulu.Kulula ukupeyinta., Umbala, ngoko ke kulungile ukusebenzisa i-abs kwizinto zokufunda zabantwana zokubhala?
I-ABS yipolymer ephezulu.Ezi zixhobo azikho inetyhefu, kodwa ezinye izongezo zongezwa ngexesha lokudibanisa, ukucubungula kunye nobunjineli.Ezi zongezo ziimolekyuli ezincinci ezinokufunxwa ngumzimba, ongumthombo wento ebizwa ngokuba yityhefu.I-PC, i-PE/ABS kunye nezinye izinto zilungile, ngelixa i-PVC ayinayo ityhefu encinci.Kucetyiswa ukuba ukhethe ipeni yokufunda yabantwana ehlangabezana nemigangatho yaseYurophu yoxolo lwengqondo xa uyisebenzisa.Okukhona umntwana emncinci, kokukhona kufuneka uthenge uhlobo olukhulu lweepeni zokufunda zabantwana.Njengoko ilizwi lihamba, ixabiso elincinci alilungile, kwaye okulungileyo akubizi.Ixabiso leepeni zokufunda zabantwana lisenokuchaza ezinye zeengxaki.
Ngapha koko, uninzi lweeplastiki azinaziphumo eziyityhefu ngokuthe ngqo kwizinto eziphilayo kuba zizinzile ngokwendalo kwaye azikwazi kusabela nezinye izinto kwiqondo lobushushu begumbi.
Ngokuqinisekileyo, izongezo ezahlukeneyo zongezwa kwiiplastiki ngenxa yezicelo ezahlukeneyo, kodwa le plastiki ihluke kakhulu.Izongezo zePlastiki ngokubanzi zibandakanya izigcwalisi ezingaphiliyo, iifiber zeglasi, iipigments, i-antioxidants, i-anti-ultraviolet agents, iiplasticizers, njalo njalo.Izihluzi ze-inorganic kunye neefayibha zeglasi zizimbiwa kunye neglasi ezinepropathi ezizinzileyo kwaye azinabungozi emzimbeni womntu.Idosi ye-antioxidant kunye ne-anti-ultraviolet agent incinci, kodwa i-dosage ye-1-2 ‰ ngokuqinisekileyo ayinayo ityhefu okanye i-low-toxic.Eyona plastiki inokuba yingozi ebantwini yiPVC.Umxholo owongezelelweyo weplastiki unokufikelela kwi-60-70%, okunzima ukuqinisekisa ukuba akuyi kuba yingozi kumzimba womntu.
Iiplastiki ze-ABS zisetyenziswa kakhulu kwizixhobo zendlu, ezifana neefriji, oomatshini bokuhlamba, i-air conditioners, ii-oven microwaves, njl., esizibiza ngokuba yimpahla emhlophe.Iplastiki ngokuqhelekileyo isebenzisa izongezo ezincinci, kwaye i-toner ecocekileyo ye-ABS isetyenziswa ngakumbi.Ngokutsho kwinqanaba langoku loshishino lweplastiki, ininzi yeetoni ziyimveliso ehambelana nokusingqongileyo, engayi kuchaphazela umzimba womntu kunye nokusingqongileyo.Ngoko ungakhathazeki ngayo, sebenzisa nje ngoxolo lwengqondo.
Kuyilo lweepeni zokufunda zabantwana, ukhuseleko lubaluleke kakhulu, kungekhona nje kuphela izinto eziphathekayo, kodwa kunye neemfuno zokhuseleko njengoyilo lweepeni zokufunda zabantwana.Ngokomzekelo, imilo yoyilo inokubangela ukulimala, kwaye inxalenye ekhutshweyo iya kubangela ukuba umntwana aginye ngephutha, ezi zinto zonke ziqwalasela ukhuseleko.Kuyilo lweepeni zokufunda zabantwana, ukukhuthazwa kokusingqongileyo noyilo olukhuselekileyo akuncedi nje kuphela ukusetyenziswa kwabantwana, kodwa kukwakhuthaza uphuhliso olusempilweni lwemarike yokubhala yabantwana yelizwe lam.
