Umayisho uqondile ngaphambi kokusebenza kulethangu le-LDPE granules, kodwa ungathanda ukudibanisa ngokucacile ukuthi yini noma yenza nini? Low-density polyethylene (LDPE) yi-plastic elingeyaziyo esetshenziswa kunesiNgesi njalo. Leshomi lingaqhubeka nge- LDPE granules, ukusetyenziswa kwazo kwindawo yokugcina kanye nokuba zingayiphi zonke izinto ezinamandla kanye nokuhlala kuhlukekile.
Amagranuli eziqephu kweLowdensity polyethylene zikhelekile izifragmenti ezincinci zephesi ezizibuyiseli kwisebe esixhaswayo usuku, osiyaziwa ngokuba ubungane, okhishelwa kusenzo lokulula. Lapho iphesi leyiyo yilokhu elithetha ukuthi yiThermoplast, yokuba kunjalo ungene ukuhlala ngenxa yesikhatsi esingabangako njengamanje namanjalo. Amagranuli apha amahhovu, asicabange ukukhombisa, kunye nokuhluphekiswa ngokukhulu. Bayakwazi ukubona imizi (bayiphawu), amakhemikali kunye nezinye izinto ezinomsindo. Kufanele ukusebenza nabo ngokushesha kumthetho wakho, ngoba bangene ngendlela engaphezulu.
Ngaphambi kokuthi sibhalele amaninzi amaphumo okusetyenziswa kweGranules le-LDPE, bhekelele ngaphezulu. Ngokubanzi, abaningi babenzi kwiinkunkuma zokuphakamisa. Ngalokho, izinkunkuma ezizikhono esihluhleni siyazi khona kwiikoti zakuvodwa, iimfuthe eziphumayo isitshwala ukuya kuhlukeni noma iibabule zokulindela amagumbi ngasemva kweeshipho. Ngaphandle kokuphakamisa, iingubo ze-LDPE zivunyelwe ukwenza izinto ezinhloko. Bazisebenzisa ukwenza amabhopho ebomvu engasebenzisa ukungena, iintoyi engeziwayo nalo, noma iindlebe zokugcina elinye leentsha. Izandla zokuqobo nokusebenza kweelektri lesedluleyo kunye nezandla zokubhedlela kuzisetshenziswa ngeGranules le-LDPE ngoba kuneenkcukacha ezincane zokushicelekileyo. Babelayisayi ukubhala amadendelethi, ukuprotekela amakhadulo, kunye nokubhala amabhebhu amacipha umoya wemilando.
Kulesi sikhathi esizame ukufunda ngokuthi ukwakha amanqaku amaplastik, kunezinye izinhlobo ezifanele ukuba zisodwa ngegranule zase-LDPE. Yokuqala, bayeneyo bafuneka kuhlala ngokusukela, yinto engaziqondisiyo ukuthi uzame ukuhlala ngaphandle kokuthi kudinga imali esizingeziweyo. Esishayamusha, zingasihlanganiswa ngendlela enkulu lokusebenza, futhi kuhlanganisa ukubheka kakhulu emfanekisweni wamanqaku angahlala ngaphandle kokuthi azibheke. Izigranule ze-LDPE zingabheka nokuphucumana okanye nokulula kwesisekelo semanqaku, lokungaba ubungako obudala obuhle kunesisekelo esidingayo. Ukusetyenziswa kwe-LDPE kunjalo ungahlanganiswa namanqaku amathermoplastic amanye aphandle kuzo kuvumeleyo kwezindlela zakwakhiwo kwezindlela zakho. Izigranule ze-LDPE zinene zibuyiselwa, lokungaba yinto eliphambili lokazo. Lokunye, ukubuyisela kubo kunabelungu labo abaningi abazama ukususa umlayezo nokuthuthukisa indawo yesikhathi.
Ezinye iindlela ezikhoyo okunye ukuthi uzogcina ngezinto zokuthi kufanele uzame lapho uqinisekisa amagranulu we-LDPE. Ngonyaka yokuqala, into ephakamileyo kulapho uzogcina ngendlela yokuhlola nokuphakamiswa kwe-amagranulu we-LDPE. Amagreyedi akhawulezanga ngumngeni wemveliso wenye into eyenzekelayo, ngakho ke kuhluke kakhulu ukuthi uzogcina igreyedi elithile lokusebenza olungathanda.
Amamethodi Amanje Akhiwa We-Amagranulu we-LDPE Kunezinye izindlela ezinikezela amagranulu we-LDPE. Izindlela ezimfanele kahle ziyinkantolo ne-extrusion, blow molding, kunye ne-injection molding. Imethodi esezisetyenziswa isebenza ngokuba yini iproduct ethile, kunye nenkinga enethintela ukuthi alindele ku-ningi. Ngakho ke, u-extrusion ungenziwa emasoreni, kunye ne-injection molding ifanele yenza imibuzo, amacandelo, ama-container, noma amanani amanye amabuthi.
Amagranuli eziyi-Low-Density Polyethylene (LDPE) zihlaba ukuthi ngokwesikhathi kwisezintsha ezithile abahleli bengxenye yokuhlala kuhlukekile ngezinto zokugcina izindlu zezemvume. Ukuthi angakho, bazoqala babekho ukuba zifunyenwe amaninimba okuningi phambi kokufakwa kumizuzwana, lokhu kungaphambili yindlela engazange zisisebenzise kumizuzwana, lokhu ngokushesha kungcono lapho zisetyenziswa. Ukwenza amagranuli a-LDPE kufanele kunyuka inkulumo yamathebhu nokukhathalela amashumi amabili amacelenthabe. Lokhu kuyasusa umoya nokubhedelela amafutha emagcinini, okuningi kakhulu lokulandelana nezinye izinto. Izintsha ezilindeleyo, ezinhle, nezingene zonke kuhlukekile zibhekise amagranuli a-LDPE -- zingabheka ukuthi zibekelela indawo ekupheleni kakhulu.
