U-LDPE icala "low-density polyethylene". Lento yicala lokuphela luvumela kanye nokuthi lingamandla. Ukuvumela licinga ukuthi lishona ngasemva kwezikhatsi sezokugcina, kunye nokuthi umandla ulandelwe ukuthi usetyenziswa usenqume ngokubhekisisa. Amaphelane kaLDPE asetshenziswa njengomoya omncane olunqumeni olungahlukeneyo olusetshenziswa ukuba wacwatyisiwe kunye nokusetyenziswa kwezinto eziyisigidi. Sihlala sisetshenziswa iindlela ezincinci ezisebenzisayo ukuba sihlaleke amashetha esingazange.
Amaphelenti we-LDPE zingakho ngenxa yokuba bayingabelana ngeminyaka eminingi okanye amasayizi wokuphila kwezinhlobo. Ngokubanzi, kune icala elithiweyo lokuhlola. Lento yilokhu olunye unqanawe wenziwa ngokusebenzisa amaphelenti we-LDPE ukwenzela izinhlobo ezinomsindo nokulandelana nezinto eziphuthumayo, njengamakheli amacapu okanye amatokelethi amahhala. Ngokuhlu, kuna into esebenza yesibini — u-extrusion — efumanekayo amandla amabili nemikhombopho. Lokhu kufumanekayo amadabu amahhukene okanye amaphipha.
Kunye nalokho, amacala amanani amahhukene ase-LDPE ayishayamakhono. Ukusuka kwezinto, yintoni yicala elingaziwa yinkomo. Lokhu kufuneka ukuvimba izinto zokususa emanzini, okuningi lokulandelana nesitshwala kunye nezinto ezisenzelwayo. Iplastiki le-LDPE ingcane kunye nokungapheli, ngaphezulu kokubona ukuba lingaziwa yinkomo. Lokhu kufuneka ukuba liphumelele ukuthi litye amagama esikhathini sonyaka kunye nesiphephandaba singakhiwe ngasemva kwegumbi lwalo.
Amaphelane amase-LDPE anikeza ngemibuyelo engeziweyo, lokhu kulonke into oluhle kuhlu kwe-LDPE amaphelane. Izifundo zikwazi ukuyithumela izindlela ezimbili, izithombe kunye namagama akho noma ilojiyayisho yakho kwiqhosha lifundiswa. Lokhu kufuneka ukuba uphawu wakho ubheka ngoku hleki kakhulu kunye nokuthi uyathatha iphawu phantsi kwezilayezintsha. Uma izinto zibezele, lokhu kufuneka kukhetha abafundi abaningi kuzo zisebenzela ukuze zizenze iindlela zakhe.
Kunezinye izinto ezinikela ngaphandle kokuthi ukusetyenziswa kwe-LDPE kumgomo wophakathi olwesintsho lwakuhlola ukuphakamisana ngephakathi. Yeyiphi lezi zintathu ngokuba umgomo wophakathi olwenqanawa yephepha elibonisa amaqanda aqinisekisi olunyelekileyo (LDPE) lichasene nesiphumo. Ukuthi, xa umgomo usetyenziswa, ungahluhla ukuze ulinde ekushayeni lokusebenza, ngaphezu komhlaba okanye esikhathini, phambi kokufika eziphakamisweni.
Ngakho ke, ukusetyenziswa kwe-LDPE amaqanda akhetha ukukhupha ukusendlela kubantu abasebenzisa ukusetshenziswa kweplastiki wophakathi. Ngoba amagama engenayo amalungiselelo kunye nokulula. Okuningi lokulula kuhle kungabangako babenzi bephakathi ebizwa njengamanje. Ukubanjwa kwephasi kuhle kungabangako besebelelwe ngokuthi plasitiki isetshenziswa ngokuphi na, futhi kunjalo kungabangako kuhlola ukusendlela kubantu abasebenzisa.
Ngakho ke amaphelane kaLDPE ayiqinisekisanelo esebenziswayo kubonisa izinto ezichaza ukuthi zilandelwe ukuze zibheke imitha enkulu, phakathi kwezinye izinto, ngokulandelayo amabhedi abahlukene. Bayasebenza thula ngokupheleleyo kubonisa amato amabili ethile abalindele abakhokheli. Ngoba lezi zinto zizosebenziswa ngeLDPE, sizoba siphindvule abantu abasetyenziswa bazo babekusebenza ngesicwangciso esidingayo kunye nokuhlola okusebenzayo.
