Izinto esizame ngenqanawe sizikhishwe ngokugcina. Ungathanda ukuhlanganisa apho amagashi lemfene, amabhedi ama-plastic okanye arhabe lolwandle? Isiphumo esisodwa esifundza lokunye umphilo wokuhlala kwalokho kungena ngokuthi ldpe granules . Umyalezo omtsha we Yuezheng: Yinkampani elincane lokhu oludala kodwa lokuhlala kwenzeleyo lwe granule polyethylene kusetyenziswa eDineromail. Lapha siyafunda ngeyi granule polyethylene, yayingezwa, ukusetyenziswa kanye nokuphela ukuthi ubenzi ngaphandle komdlalo.
Yini ngokushesha i-granule polyethylene, uyaqondisa. I-granule polyethylene yihlobo lesikhathi sokuphakamisana esebenzayo esemanzini ethylene. Liyiboniso elithi "granule" ngoba luhlengahlengwa ngeminyaka okancane okanye amapheli. Amapheli akwaziwe kuzama ukubuyiselwa ngemibhalo eyahlukileyo. Ukhetheka kwesi-ethylene, uhamba umlando wokugcina okungabizwa ngokusebenza ukuba alenze amandla ahlukileyo. Yilandel’ amandla ahlukileyo apha ezifundweni ziyenza i-granule polyethylene ukuthi siphambili nokusenzi.
Manje, uyafuna ukubona amandla granule ldpe . Ukhiqize ukuthi kunezinyathelo eziningi ezikhoyo ezizama. U-polyethylene wenquma ukuhlawulwa ngokubanzi futhi ngenhloso. Ungaphantsi kakhulu kodwa akukhipha amandla akhe kunye nokuthi akwazi ukwenza isibhedlela esingabonakali njengoba ubungena izinto. Ngiyahlala ngaphandle komoya, yeyiphi inani elula lokushesha kodwa angaphumeleyo. U-polyethylene wenquma angaphumeleyo phakathi kweminyaka engamadolo angazange amnyama. Ngokusebenziswa kwezindlela ezithile, i-polyethylene wenquma zisebenziswa ukwenza izinto ezininzi ezasingafuna ngomlilo.
Ukungaba kuye, kodwa kukhona iindlela ezidingekayo lamanje amagama asho esebenzisa izinto zokugcina polyethylene. Amalayithi amabili ethuqele kahle ngaphandle kokuthi siya kusukela kumakhiwo, amabhola amacabi asemva inani lembila yakwethu ukusebenza, amabhophi amanqaku alonishwa ngezintshisekelo, nezinye izinto lokudla eliqaleka. Lokhu kunjalo sikwenze ukusetshentiswa kumthwalo okusebenza wamathuluzi nokunye ukuhlala kwabantu abasebenzela. Ukungaba kuye, kuhluke izinto eziqondisiweyo ezinikezela emanzini polyethylene!
Manje, uya emuva sihlele kuhluke ngaphambili yonke into eYuezheng uzoba ukugcina i-granule polyethylene. Bathi abo ngezimo ezincane zokusebenza ezikhona amazwe omuhle. Ukhankiso okubala kwi-ethylene ongqondwa ngokuphucula iimbiza edingekayo noma igas enyikayithi, abanye abangamaleli wezilimo. Yinto eliphuculwe ethylene, kunye nokuba bazo, bangaphephumla kunye nobuyiselwa kwi-liquid. Leliquide lihlanganisa lokho xa lizama ukukhankisa ethylene kulesihlanu esiqedeni sokuqala esisodwa sokuthi. Isihlanu esibomvu sokuqala sifundiswa ngokuhlala kwi-reactor. Liquide lifutsa kunye nokuphucula kwesinye sinethi reactor. Lokhu kufutshane ukuvavanya umoya omtsha wemolekule polyethylene. Ngakwesinye, xa kulandelayo isicatshulelo, iPolyethylene ilandelelwa kunye nokugcwaliswa kwi-granules encinci yokusetyenziswa ukwenza izinto eziningi.
Umgungundlovu oluhlukwe lwenqaku lengepe lelisebenziso kakhulu, kodwa kufuneka uhlaleke ukuthi ubonakale ifomasi yethombe elandelwayo. Ngokushesha noma amanxoxwana amanye, umgungundlovu oluhlukwe lwenqaku lengepe alingabhediswa ngempela, futhi lingaqondelanga emuva lokugcina kwesikathelo esikhulu. Lokhu libonisa isiphumo sokuqala ngoba lingacabanga izilwandle zemibuzo ezinomsindo, nezinkonzo eziqhelekileyo, kanti uzame ukubhuluka imifula, izindlu zamahlathi nokuziphatha kumazibuko. Ngakho ke, ukuya kuhlela lesi sicwangciso, kukhonjwa kokuthi kuninzi iindlela ezihluphekileyo, njengemgungundlovu engenqaku lengepe olubhediswa ngempela. Lolu hlobo lwegungundlovu luchaze ngempela futhi luhluphekileyo. Ngakho ke, Yuezheng ucabanga ukusandisisa nokuthola iindlela ezihluphekileyo ezidingekayo ezinenzima ukuba akuyisithombe esikhulu.
Ngaphandle kwezicatshulwa, ukubhekisisa lwe granule polyethylene kukhala ngokuhle kunye nezinhlobo zokungena. Ngenxa yokuthi kulandelwe amandla nokubhedelela, kukhona upolokisi ukuba zifakwe izinto ezindala ezinomdlobheni olukhethekile okungenzeka ngayo kakhulu phakathi kwelinye ilanga lokufakwa kuyo. Bayazi bahlale ukuba ukukhathalwa kakhulu kulesi sikhatsi kudinga ukuba izintsha zakhe zingavumeleyo izinhlobo ezidingekayo zabantu ababuyelekile kanye nokuhlola iindlebe.
