Abantu akuzona kuphela izinto eziphilayo ezikhiqiza ama-hormone. Futhi izilwane nezitshalo zinalo leli khono. Enye yamahomoni ezitshalo adume kakhulu futhi asetshenziswa kakhulu yi-ethylene, izicelo zazo ezahlukahlukene.
Uma ufuna ukwazi kabanzi ngale hormone yesitshalo, ngincoma ukuthi uqhubeke ufunde le ndatshana. Sizokhuluma ngokuthi i-ethylene iyini, yenzelwe ini nokuthi ungayithola kuphi emvelweni. Ngaphezu kwalokho, sizoxoxa ngokuthi yiziphi izithelo okungafanele ziqoqwe epanini lethu noma esiqandisini ngenxa ye-ethylene.
Yini i-ethylene futhi yenzelwe ini?
Kunamahomoni amaningi ahlukahlukene hhayi kubantu kuphela, kepha nasezilwaneni nasezitshalweni. I-Ethylene, isibonelo, i-hormone yezitshalo ngesimo segesi. Inhloso yayo lawula izinqubo ezihlobene nobudlova nokuvuthwa zombili izimbali nezithelo nemifino. Ngakho-ke, yaziwa nangokuthi i-hormone yokuguga yesitshalo.
Lapho lo gesi wakheka, le mifino ivuthwa ngokushesha, okugcina kubangele ukulahleka kwekhwalithi nokuncipha kwempilo yayo yokusebenziseka. Ngaphezu kwalokho, kunezinhlobo ezithile zamagciwane mahhala emoyeni ezingathinta nekhwalithi yezimbali, izithelo nemifino, futhi ezandisa ukwanda kwazo lapho kune-ethylene emvelweni. Ngale ndlela, izicubu zezitshalo ezibolayo ziyawohloka.
Ngokuqondene nokusetshenziswa kwe-ethylene, kunezinto eziningi ezisetshenziswayo zale hormone. Ngokuvamile kusetshenziselwa ama-plasticizers, ukumboza, izixazululi, kanye ne-antifreeze. Ukusetshenziswa okunikezwa ngokuyisisekelo kuncike enhlanganisweni. Ake sibheke ezinye izibonelo:
- Polyvinylchloride: Ulwelwesi lwezindonga, phansi, amapayipi, amathangi, njll.
- Polyethylene: Amashubhu, amapayipi, amadreyini, iziqukathi, izingxenye ezakhiwe nge-thermoformed, ukwahlukanisa, njll. Kuyinto ephikisayo futhi eguquguqukayo.
- I-Polytetrafluoroethene: Ama-gaskets, ama-bushings, ama-cookware liners. Eyaziwa nangokuthi iTeflon.
- Polyacrylonitrile: Ukwenza imicu yendwangu. Kuyinto eqinile futhi elula ukudaya isakhi esingasontwa.
- I-Ethylene oxide: Amakhemikhali aphakathi nendawo ekwakhiweni kwama-non-ionic detergents, i-ethylene glycol, i-polyethylene glycols kanye nemikhiqizo yawo. Ibuye isetshenziswe njenge-fumigant. Unguketshezi noma igesi engenambala, evuthayo futhi ephathekayo.
Itholakala kuphi i-ethylene emvelweni?
Njengoba sishilo phambilini, i-ethylene yihomoni ekhiqizwa izitshalo. Kokubili izimbali nezithelo nemifino yizinto eziphilayo eziqhubeka nokuphefumula nangemva kokuvuna. Lapho bephefumula, abakhiqizi nje kuphela i-carbon dioxide (CO2) namanzi (H2O), kodwa futhi ne-ethylene (C2H4).
Ngokuqondene nezithelo nemifino, imiphumela emihle ye-ethylene ihlukahlukene. Ngesikhathi sokuqala kwezithelo nemifino, banezinhlanganisela ezinobuthi ezinyamalayo lapho zivuthwa. Ngakho-ke, ngenxa ethylene baba ezidliwayo. Ngaphezu kwalokho, ithambisa ukuthungwa kwayo. Amazinga wesitashi ne-asidi nawo ancishisiwe, kanti izinga likashukela liyakhula. Ngale ndlela izithelo nemifino iba tastier. Elinye iphuzu okufanele uliqaphele ukuthi le hormone ithuthukisa umbala wesikhumba nephunga abalikhiphayo.
Kodwa-ke, ngemuva kokuqoqa izithelo nemifino ngesikhathi esifanele sokuvuthwa kokumaketha, yonke le miphumela ezuzisayo ye-ethylene ayisasebenzi. Lapho izithelo sezifinyelele ekuvuthweni okuhle, ziyaqhubeka nokukhiqiza le hormone, egcina ibangele ukuguga ize ibole.
Yiziphi izithelo okungafanele ziqoqwe?
Njengoba igesi, i-ethylene ihlala imvelo. Kunezithelo nemifino evelele ngokuba ngabakhiqizi abakhulu bale hormone, kanti abanye bayazwela kakhulu kuyo. Lezi zinhlobo ezimbili akufanele zihlanganiswe ndawonye, ukuvimbela iqembu lesibili ekuwohlokeni ngokushesha. Lapho isithelo esivuthiwe sesikhipha i-ethylene, ukuvuthwa kwezithelo ezisizungezile kuyashesha. Ngale ndlela aqala ukubola ngokushesha okukhulu kunokujwayelekile. Ezinye izibonelo zalokhu kungaba okulandelayo:
- Izaqathe: Bathola ukunambitheka okumunyu.
- I-asparagus: Amaqabunga awo akhuphula uburhabaxa.
- Ulethisi: Kuvela izindawo ezibomvu.
- I-broccoli: Ilahleka umbala.
- utamatisi Imifino Esivuthiwe: Ziba ntofontofo.
- Amazambane: Isikhumba sishwabana bese siqala ukubola.
Kunalokho, ezinye izithelo nemifino kuveza ukukhiqiza i-ethylene eningi. Ngakho-ke, akufanele ahlanganiswe nalawo ashiwo ngenhla. Sizobona ngezansi uhlu lwezithelo ezikhiqiza igesi ethylene kakhulu:
- I-Avocado
- I-anyanisi
- Ama-Plums
- I-Apple
- i-Mango
- UMelon
- Banana
- utamatisi
- Amagilebhisi
Ufunda okuthile okusha nsuku zonke. Uma ungazi ukuthi yini i-ethylene, ngiyethemba ngiwucacisile lo mbuzo. Ngaphezu kwalokho, kuyasebenziseka kakhulu ukwazi ukuthi yiziphi izithelo nemifino okungafanele zihlanganiswe ukuze zihlale isikhathi eside zintsha futhi zimnandi. Ngale ndlela songa imali encane lapho sithenga futhi sigcina izinzuzo ezingalethwa yile mifino isikhathi eside.
