Umkhombithi oluthiwe ngumneyambo uYuezheng uhlanganisa iindlebe ezininzi zephesi etholakalayo kwiqhosha nezinye izindawo zokugcina amakhanda. Baphetha iindlebe eziphathelene ngeeminyaka engaphezulu emibini okufanele nokuphumelela ukubuyiselwa, ezaziwa ngokuba amaresi. Lomnyama umphatho wokubuyisela ukuthi amapesi angahlala ngaso abasebenzi nobungako bophakathi. Baphetha imininingwane yamaresi ezikhona kakhulu njenge-polyethylene, polypropylene, PVC, nylon, kuningi loko. Imininingwane yamaresi engeziwayo iyabiza amandla nokusebenza kwabantu. Amanani amadiffee amaresi amaningi akhetha amandla okudingekileyo esabeleni sokuqinisekisa iindlebe.
Umthongamuzi omphambili owamiswa ukwenzela amabhedi amaphlastikhi yihlukwe lomkhuhlane. Ukhuphukile kakhulu, ungenzimane nesikhathu esijulileyo futhi ungakhipha ngasemva kokubhengisa ngokubhekisisa. Kuyinto eliphawuli lebhedi sibhala sithi siyayithemba ngezinsuku ezintathu kunye nokuya emagumbeni. Sizoba uqondise polypropylene isiqephu sesikhatsi? Leli lento olungaphezu komkhuhlane okanye, ngoba lingakhipha kakhulu kunye nokuhlala ngokupheleleyo ngemikhatsi eyishumi. Lokunye lokusebenza kulula ukuba zibe abhabhedi abazosetyenziswa ngezinto eziqhumeleyo noma abhabhedi abazotyebisa ngemikhatsi. Polyvinyl chloride (PVC) uzamiswa ukwenza amabhedi amandla. Amabhedi amanani amaningi umuntu wabona uboniso bazo ngenxa yalokho ungabona yini yenzi. Lokunye lokusebenza kulula ukuba zityenziswa ngokushicilela izinto ezidingekayo ngenxa yalokho umuntu wabona uboniso bazo. Umbhedi omncane, nylon, uzamiswa ukwenza amabhedi amandla ahlukile ayisetshenziswa ngezinto eziqinileyo njengezwi noma iiluthi. Ungakhipha kunye nokusetyenziswa kakhulu.
Amaphelenti ezi-LDPE zingasemva kunye nezincane. Zingavakasha ukusebenza ngokubanzi kakhulu ngenhlobo yephelela elincinci kulomphelenti we-high-density. Ukuthi ngakho, zingacala ngemphelela encinci, futhi zinakwazi ukusetshenziswa ukuba zifake amabhedi amancane. Lezi zisebenza kakhulu njengamagroceries okanye imibiko emncane ngoba zingasemva nokugcina nokugcwalisa. Ngakwesoku, amaphelenti we-high-density polyethylene zingasemva, zingaphezu kakhulu, kunye nephelela elincinci lokulanda. Lemiphumela usebenziswe ukukhetha amabhedi akhawulezi ahlukile ahlukileyo okungaba ezinye ziya kuhlala ngokuphathelana ngezinto ezindala ezinendledele. (Izinhloso zakhiyiwa eziningi zisetshenziswa kwiqhaza okanye ukukhutshwa izinto ezindala.)
Ukudibanisa umphathelano kunye nokuhlola kwezicatshulwa zeplastiki, Yuezheng uzama ukubhala amaxesha angazange amaphelenti we-polyethylene. Lolu hlobo lwe-amaxesha lizama ukuthola umkhondo kunye nokuhlola. Lizaqinisekisa ukuba lezi zicatshulwa azite, azitshetse okanye azibonele kuqala, futhi zihlola phakathi kwesintu, nhlobo, kunye nemveliso, ongafanele abeze zisebenzise phandle kwezikhaya.
Amagama amaningi elizenzekelayo eYuezheng ziyazinga izicatshulwa, izilungisi zokubhujabhuja, kunye nezindlela zokuqaphepha UV. Izicatshulwa zidingezwa kwiipelenti yasendaweni ukuvumelanisa umoya wemakheli emibhalweni kwebhedi ebhagwaneni. Ukukhulula ukufinyelela nokufakelwa kweebhagwana ngaphandle kokubhujabhuja. Izilungisi zokubhujabhuja zidingezwa ukuze ebhagwana bayiphumeleye, ngisho xa bingene njengamanje ngaphandle kokubhekana ngeenyanga. Lento kuhlonipha ukuba abhagwana abangena ngeenyanga azibhedele. Iindlela zakuvavanya UV zizwangazwa kweebhagwana ukuze angasebenzi ngonyanga. Lento kuhlonipha ukuba ebhagwana bezisekukhona ngokushesha, ngisho xa kulandelwe phandle komkhaya.
Umnikazi olushesha kakhulu lokungafakeweki luhlengane ngeplastiki elibuyiselwe ngakwesokudla, futhi lokhu kuzo kusenzo esikhundleni sokugcina amalayithi. Kodwa, ukukhetha kuhluke kakhulu. Plastiki elibuyiselwe, ngakwesokudla, uhlanganisa isidingo senqanawe kunye nokubhekisisa izinyathelo, okuningi lokulandelana nezindlu zezilimo. Okuhle kakhulu ukusetshenziswa kweplastiki elibuyiselwe ngakwesokudla, ngoba angaphumeleyo ngokuphephile kakhulu kanye nokufakelwa kwamalayithi asehlulekileyo kunye nokukhuphela ukusuka kwezindlu zezilimo.
Ukuthi uprosesu lwesikhiqizelo silungisiwe yisigaba esingekho lokunye nezinto ezimbili njengomgena wemperiphethe, umoya nokubuyiselwa kwekheli. Ngokusebenzisa ukubuyekeza kakhulu kwezi zinto, Yuezheng ziqinisekisa ukuthi ziqukethe amabhedi amahlukeni amacabango enkulu echanekayo ngesidingo, ukuhlengane kunye nokuphucumana. Lento yokuhlola kuhluke kakhulu lokusetshenziswa kwebhedi abangene nesicwangciso sakuxoxwa kunye nokuthi bavale amagcindebe alawulwe ngasihlobo sokuvala izinto eziningi.
