Isimo semvelo somhlaba wonke sidinga ukuthi sisebenzise izinsiza kanye nokuchitha imali ngendlela eqaphelayo nenesibopho. Izikhwama ze-PEVA seziba yindlela ethandwayo esikhundleni sezikhwama ze-polyethylene nezephepha zendabuko. Izinkinga ezihlobene nomthelela wazo emvelweni zithakazelisa kakhulu kochwepheshe nakubathengi abavamile. Kulesi sihloko, sizocabangela umthelela wezikhwama ze-PEVA emvelweni, izinzuzo kanye nokungalungi kwazo, nokuthi yiziphi izinyathelo ezingathathwa ukunciphisa umthelela wazo omubi. Lezi zici zibalulekile ekuqondeni indima yezikhwama ze-PEVA ezweni lanamuhla kanye nokwenza izinqumo ezinolwazi mayelana nokusetshenziswa kwazo.
Iyini i-PEVA futhi kungani ibalulekile?
I-PEVA (i-polyethylene vinyl acetate) iyi-polymer yokwenziwa esetshenziswa ekukhiqizweni kwemikhiqizo eminingi, okuhlanganisa nezikhwama. Inezakhiwo eziningana ezenza ikhange ukusetshenziswa: ukuguquguquka, ukumelana namanzi kanye namandla. Ngokungafani ne-PVC, i-PEVA ayinayo i-chlorine, okwenza iphephe empilweni kanye nemvelo. Ngenxa yalokhu, izikhwama ze-PEVA ziya ngokuya zithandwa. Kodwa-ke, umbuzo womthelela wazo emvelweni usavulekile.
Esinye sezici ezibalulekile ukungabikho kwezithasiselo ezinobuthi kule nto. I-PEVA ibhekwa njengengalimaza kakhulu abantu kanye nemvelo kunezinye ipulasitiki eziningi. Kubalulekile ukuthi izinto ze-PEVA zibole ngesikhathi esincane ngaphandle kokukhipha izinto ezinobuthi - lokhu kwenza kube yindlela engcono kakhulu yokuvikela imvelo esikhundleni sezikhwama zepulasitiki.
Izinzuzo Zokusebenzisa Ukudla kwe-PEVA
Phakathi kwezinzuzo ezibalulekile zokusebenzisa izikhwama ze-PEVA, singaqokomisa ukusebenziseka kwazo kabusha kanye nokumelana nezimo zangaphandle. Isikhwama sokudla se-PEVA esineziphu sikuvumela ukuthi ugcine ukudla ngokuphephile ngenxa yokuqina kwaso, ukuvimbela ukubola kanye nokunciphisa inani lemfucuza yokudla. Lesi sici sibaluleke kakhulu ekunciphiseni inani eliphelele lemfucuza yasekhaya, elinomthelela omkhulu emvelweni.
Izikhwama ze-PEVA zilungele ukugcina hhayi imikhiqizo yokudla kuphela, kodwa nezinye izinto. Ngenxa yamandla azo nokunwebeka kwazo, zingasetshenziswa ngokuphindaphindiwe, okunciphisa ukusetshenziswa kwamaphakheji alahlwayo. Ukulula kokunakekelwa kwazo nokuhlanza kwenza inqubo yokusetshenziswa kwazo ibe lula futhi ilungele abathengi.
Izici zemvelo zokukhiqiza nokulahla
Inqubo yokukhiqiza izikhwama ze-PEVA ibangela ukukhishwa okuncane komoya okubangelwa ukukhiqizwa kwemikhiqizo yepulasitiki efanayo. Lokhu kungenxa yamakhemikhali ayinkimbinkimbi kakhulu kanye nezindleko zamandla eziphansi. Kodwa-ke, inqubo yokuvuselela izikhwama ze-PEVA ngokwayo ingaba yinkinga ngenxa yokuntuleka kwezinhlelo ezikhethekile kanye nobuchwepheshe bokuvuselela kwazo.
Ngokuvamile, izikhwama ezinjalo zigcina zisezindaweni zokulahla udoti, lapho zibola khona, nakuba zishesha kunepulasitiki evamile. Ukusekelwa nokuthuthukiswa kwengqalasizinda yokusetshenziswa kabusha kwazo kuzosiza ekunciphiseni umthwalo wemvelo. Ukufaka uhlelo lokuqoqa nokusetshenziswa kabusha kwezikhwama ze-PEVA emizamweni kahulumeni kungaba yisinyathelo esibalulekile kulokhu.
Umthwalo wemfanelo womphakathi kanye nokusetshenziswa okuqondile
Ukusebenzisa izikhwama ze-PEVA ngokuqonda kungaba yingxenye yesu eliphelele lokunciphisa umthelela emvelweni. Abathengi bangasiza ekulondolozeni imvelo ngokunciphisa imfucuza engaboliyo nokukhetha ezinye izindlela ezinobungani nemvelo.Isikhwama sokudla se-PEVA esine-zip-lockingenye yezindlela ezinjalo.
Ukuphakamisa ukuqwashisa ngomonakalo wepulasitiki esetshenziswa kanye kanye nokuyifaka esikhundleni sezikhwama ze-PEVA kungashintsha kakhulu izindlela zokusebenzisa. Njengengxenye yalezi zinhlelo, kubalulekile ukuqhuba imicimbi yezemfundo kanye nemikhankaso eyethula abantu emathubeni okukhetha okunesibopho semvelo.
Amathemba nezinselele zesikhathi esizayo
Ukuthuthukiswa kobuchwepheshe bokuvuselela i-PEVA kanye nokutholakala okuthuthukisiwe kwezinsizakalo ezihlobene kuyizinyathelo ezibalulekile zokwandisa ukuzinza kwale mboni. Imizamo kule ndawo kufanele ihloselwe ukudala izinhlelo zokuvuselela ezingcono ezizonciphisa umthelela wemvelo.
Iphuzu elibalulekile ukutadisha nokusebenzisa ubuchwepheshe obuhlukile bokukhiqiza izinto ezinobungani nemvelo, okuhlanganisa nezinketho ezingasetshenziswa njengomquba. Ngokuhamba kwesikhathi, lokhu kuzonciphisa ukuncika kuma-polymers okwenziwa futhi kuqhubekele ekusetshenzisweni kwezinsiza ngendlela eqhubekayo.
Intshisekelo yezikhwama ze-PEVA iyakhula, ngaleyo ndlela idala isisekelo socwaningo kanye nokusungula izinto ezintsha emkhakheni wokusetshenziswa kwazo. Izinhlangano zobungcweti kanye namabhizinisi angadlala indima ebalulekile ekusekeleni nasekuthuthukiseni lo mkhuba onobungani nemvelo.
Isiphetho
Izikhwama ze-PEVA ziyisinyathelo sokusetshenziswa okunombono ongcono ngemvelo. Uma zihlanganiswa nezimfanelo ezifana nokusetshenziswa kabusha, ukuphepha kanye nokuqina, zingathatha indawo yezinhlobo eziningi zepulasitiki ezilahlwayo.Isikhwama sokudla se-PEVA esineziphukungaba ithuluzi lokunciphisa inani eliphelele lemfucuza kanye nokunciphisa umthelela omubi emvelweni. Kodwa-ke, kudingeka imizamo eyengeziwe ukuthuthukisa ubuchwepheshe bokuvuselela nokucubungula, kanye nokwandisa izinga lomthwalo wemfanelo kokubili kubakhiqizi kanye nabathengi.
