Ukuqonda Izinto Ezisetshenziswayo Ze-EVA Ezinganeni Zanamuhla IMIKHIQIZO
Ukuphelelwa nokhonga kwebhulowezo zabantwana nezinhlobo zezinto ezifanelekileyo zakhothazwa njengendima ebalulekile kakhulu kubabekhetha nabagcini. Ngaphambi kwamathambo afuthiwe, akhona EVA (Ethylene-Vinyl Acetate), ipholimha engamazinga ethembekile yokuba yenzakalalelayo, eyayiphinde iphinde isebenziswe ngokushesha emgcineni webhulowezo nabanye amathuba okugcina abantwana. Leli thambo linikeza ukuphelelwa, ubunzima, nendalo enobukhona, lokhu kuyakha kungcono kakhulu kuzinto okubantwana bazohlaba ngazo ngokudla
Ubuhlebantwana be-EVA ezinhlanzini zezintombi bakhishwa kizindlela zakhe ezihlukileyo - emnandi kodwa enembile, engahlengi majika kodwa emncane, kanti ngaphezu koko, ayithintshi futhi iphephile kumadodana amancane. Xa sifinyelela ngaphandle kwe-EVA ezidulini nezinhlanzini zezimali, sizohloloba kanjani leli thambo libe yisivikelo sezinhlanzi kanti ke ubazali basekhaya bonke baphathelela izinhlanzi ezinzululwayo ngalesi thambo ethu.
Iziphawu Ezimbala Nempumelelo Yeziphawu Ze-EVA
Iziphawu Zomthamo Ezakhiwa Ngazo EVA Iyiyilide KumaBantwana
U-EVA unobuchwephesha obunikile okungafanayo okwenzela ukuthi kube yisikhathi esifanele ezinhlanzini zomntwana. Lomshwalense wenza ukuthula kakhulu, okubaluleke ekulindeleni izinhlanzi ngenkathi zidlala. Isimo saso esiphazanywayo sikhuphula izinyama ngaphandle kokushiywa isimo sesithunzi. Ngaphezu koko, ubuncane besithunzi bekhipha izithixo nezinto zibe yimfanelo engcono kumashandila amancane.
Isakhiwo sefothi yeselikalaka somshwalense sabelana nokukhanya okuhle nokukhathazeka kwamanzi. Lokhu kwenza u-EVA ezingqongweni kakhulu ezinhlanzini zokudlala emanzini, ezinhlanzini zasephondweni, nezinhlanzi zokudlala phesheya. Isayithi esingavume manzi sikhuphula ukuthembeka kwamanzi nokuthutha kwamabhaktera, kuyakha isiqiniseko nesiphilwayo ngokude.
Amastandela Wesiqiniseko kanye Nezici Ezingavamile
Xa kufaneleke nezinhlanhla zomntwana, ukubhaliswa ngokuphatha kungasingenziwa. I-EVA iqinisekisa nokuphumelela ema-nhlalo ephathekayo ezihlwayelweyo yezinhlanhla zezindlela namakhiyapo abafundi. Isici singasizange siqinisekile phakathi kwezinto ezihlukile njenge-BPA, i-phthalates, nemitholwane engenamandla, okwenzela ukuthi kusafe kumantwana abangayithathela izindlela ezimlonyeni.
Umbono wokungabi nentsha we-EVA ungcwalisa ngaphandle kwebala lakhe. Isici sinemvelaphi yokunqula ukuziphazanyiswa kwizici eziluhlaza kumantwana. Isahluko sakhe sikhuhlane sisebenza ngokuthula futhi kususe ukulahla, okunciphisa umsindo wokulahlekelwa komphakathi wokudlala.
Imisebenzi ekwakhiweni kwezinhlanhla ezintsha
Izinhlanhla zokufundisa nezinhloso zokufunda
Abakhi beli gqirha lezifundo baya ngokukhulu kuma-EVA ukwenza izicelo zokufunda ezibhekene. Kusukela kuze kube yizinkawuli zomlomo kuya kubalishi, i-EVA kuligqirha libe yindlela eqhele yokulungisa ububi nokusebenza. Ubunzima beziphathi kumelwe kubekwe emibhalweni enjalo futhi kumelwe kubekwe emibhalweni ephathelene, ukwakha izixhumanisi ezibonakala njalo ezibhekene nempilo yabantwana.
Ubunzima be-EVA buhlinza ukuthi ligqirha lezifundo libe lishape phakade noma kusetshenziswa kangakanani. Lokhu kubuyiselwa kumelwe kubuyiswe kakhulu kuzintolo nezibopho zokufunda, ngelikasikhathi labalulekile kakhulu kuthutha kanye nokuthutha kwazo.
Izixhobo zokudlala phandle kanye nokusebenza
Emhlabeni wokudlala phandle, i-EVA ibonakala njengomthelelo ongcono ekwenzeni amathoyi athembekile kakhulu noma akwenzeki ngumoya. Izixhobo zendawo yokudlala, izidumbu zokudlala, nezizinto ezinjalo zikwenzeka ngokulungileyo ngemali yokuqhuba nokulondoloza kwamathoyi aphakeme. Ukukhathazeka kwe-EVA kwi-radiation ye-UV nezinto zokulima kusenhlalweni kusibonisa ukuthi amathoyi aphakeme ayithembeka futhi asebenze kahle ngokude.
Izinhlahla zokudlala ephindwe ngokusebenzisa i-EVA zabelana ngokuphelele kwezimali zokuphepha nokudlala. Kusukela kuze kube ngendlela yokuphepha kuya kumatifu okudlalwayo, imali yesiphashaphathi iyasiza ekukhulenisa izikhundla ngexesha lenzeke ngokwenza imisebenzi yezinye nezihlukanisa.
I-EVA emathoyini asemadodana
Izinto zokuphepha kwindlu yosindiso nendlu yosulwa
Umphakathi wendawo yokuphila kufuneka kube nemizamo ephelele yokuhlonza, futhi i-EVA inikeza okwanele kule ndawo. Izixhobo zokulungisa izindlebe, izihlalo zokulungisa, nezimbotyana ezinzima ezinzima ezenziwe nge-EVA zinikeza ukulungiswa okubalulekile kubantwana abahamba noma abadala. Ubunjwale bokwelashisa bekha kakhulu ukulungiswa kusenjini kodwa kakhulu kugcina izici zakho zokulungiswa ngexesha.
Isiseko se-EVA esisetyenziswa emathiselweni aphakathi kwindlu yokuphila, indawo yokudlala, nokuzingelana. Le zinto zenza indawo ehloniphekileyo yokuzifundela kubantwana abancane nakuba bafundi, ngelishwa babengcono ngokuthi bahlonyele njengoba bethembeka ngokuphelele kwabankomo.
Izinto Zokuhlambela Futhi Zokuthutha Kwasekuqaleni
Ngexesha elibhekene nokuhlambela, i-EVA ibonakala yisicelo esihle sokwenza izidlo zokuhlambela ezihloniphekileyo, ezingcono. Ubunjwale bayo obunjwale kodwa obukhanyayo benikeza ukuqhubeka okufanelekileyo kwegumbhu lapho kuthutha, kodwa ubunjwale kakhulu ukuthi akuthintele. Iziphawu zayo ezingavamile zikhethekile kule xesha lapho abantwana abancane banquma izinto ngokumgcilwa.
Izinhlanhla zokuphuhlisa kuqala eziqukethe i-EVA zikwakha ukuthenga kwezinsukwane ekuhlakaniphisayo kubantwana. Kusukela kizindlela ezinezithunywa kuya kizinkinobho ezifakelwa ngokushaya, lezi zinhlanhla zihlalisela ukuphuhlisa kwemisebenzi yomzimba ngexesha elijolise izimo ezikhulu zokuphepha.
Ukwenziwa nokugcina ubunzima
Imigomo Yendawo Yokwenza Nezibophelelo
Ukwenza kwezinhlanhla ze-EVA nezinhlanhla zebantwana kufollowa imigomo engcono yokulawula ubunzima. Ngamnye amandla okwenza kuthathwa ithiSTI ejulile ukuqinisekisa ukuba kuyiqiniso nemigomo yethusi eliyintshonalanga. Kusukela ekukhetheni izinto zokudala kuya kuthiSTI yekugcina yezinhlanhla, abasebenzisi bakhuselela imigomo embijabeni yokulawula ubunzima.
Iindawo zokwenza zilondoloza iimeko ezilawulwayo ukuze zilungiselele ukulahlekiswa kwaye ziqinisekise ubunzima obugcwele bezigunya. IthiSTI ejongo ngokuphindaphindiwa ngezinto eziphazanyayo nokukhokeleka kwegunya kunceda ukulondoloza ubunzima obungaphezulu obuthiThunywa ngezinhlanhla ze-EVA.
Ukuvuselelwa Kwizibuko Zokwenza
Ukuthuthukwisa okuphambili kakhulu kwe-teknoloji yokwenza i-EVA kubangela ubunzima obuhle kakhulu kwezinto nokwakha kwezindlela zokuphepha. Izindlela ezintsha zokwakha zivumela ukulawula ngqondene kakhulu kwezinkinga, ukuzizwa, nokukhula kwemitholampilo. Lezi ziphanywayo zibangela izinto eziphila ngempela kakhulu ekusebenzeni kazo ngaphandle kokugcina amandla akhona okuphepha.
Izimiso ezihlakaniphileyo zokwakha zifakelwa ngokuphindaphindi kwi-EVA, zilungiselela ukuncipiswa kwezingo zaseMhlaba ngaphandle kokushintsha ubunzima bempilo. Lokhu kusiza ekunikelwa kakhulu kwezinto ezinjalo ezibhakithiwe ku-Tinyekani.
Imibuzo Evame Ukubuzwa
I-EVA iyisafety kangakanani kumaTinyekani ukudla kuyo?
I-EVA ihlangabezana njengenzo isafety kumlando wokudla futhi isetshenziswa kakhulu kumagijongo okudla. Lomthebetha awunanto, awune BPA, futhi uyakhiya imikhuba eminingi yokuphepha kwezinto ezibhakithiwe ku-Tinyekani. Kodwa, qiniseka ukuthi uvatha kumagijonga amehlo angcono futhi ujonge ukuthi kuyini okufanele kusetyenziselwa ngokulinganayo.
Izikhathi ezimangalisayo zingaki-phi izigijimi ze-EVA?
Uma zinakekelwa kahle, amathoyizi e-EVA angahlala iminyaka eminingi. Le nto ihlala isikhathi eside futhi ayigqwali. Nokho, hlola njalo amathoyizi ukuze ubone ukuthi awonakele yini futhi uwafake amanye uma egqoke kakhulu ukuze ugcine izindinganiso zokuphepha.
Iyiphi Indlela Engcono Kakhulu Yokuhlanza Amathoyizi EVA?
Amathoyizi e-EVA kulula ukuwahlanza ngensipho namanzi. Zisula ngendwangu noma ngesiponji esimanzi, bese uzihlanza ngokuphelele ngaphambi kokuzisebenzisa. Gwema amakhemikhali anolaka angase alimaze ukuqina kwale nto. Ukuze uhlanze ngokuphelele, ungasebenzisa izixazululo zokubulala amagciwane eziphephile ezinganeni eziklanyelwe amathoyizi ngokukhethekile.
