Ngaba luhlobo luni lweplastiki?
I-PE (Polythylene, iPolythylene) yenye yezona zinto ziqhelekileyo ze-thermoplastics ezisetyenziswe kwicandelo lekhemikhali. Isetyenziswe ngokubanzi kwimimandla eyahlukeneyo kwaye iba yinto yokhetho kumashishini amaninzi ngenxa yepropathi yakhe ebalaseleyo kunye noqoqosho. Kweli nqaku, siya kuhlalutya ngokweenkcukacha iintlobo zeplanga ze-PE, iipropathi zabo kunye nezicelo zabo eziphambili zokukunceda ukuba uqonde ngcono izinto ezibalulekileyo zeplastiki.
Amagqabantshintshi asisiseko yePlastics
Iplasitiki (i-polythylene) i-polymer yezinto eziveliswa yi-polymerication ye-Ethylene Monomer. Kuxhomekeka kuxinzelelo nakwiqondo lokushisa ngexesha lenkqubo ye-polymeris, i-Pesticy inokuchazwa kwiintlobo ze-Polythylene (i-ldpe), i-Polythylene ye-Polythylene (i-HDDE). Uhlobo ngalunye lweplastiki lunesakhiwo sayo esikhethekileyo kunye neepropathi zemeko eyahlukileyo yesicelo.
Iintlobo zeplanga ze-PE kunye neepropathi zabo
I-Polythylene (i-ldpe)
I-ldpe iveliswa yi-Polymerication ephezulu ye-Ethylene, equlethe imixokelelwane engagungqiyo kwisakhiwo sayo kwaye ngenxa yoko ibonisa isidanga esisezantsi se-crystallity.dd, kwaye isetyenziselwa ukuveliswa kwe Iifilimu, iingxowa zeplastiki kunye nokupakishwa kokutya. Ngaphandle kwamandla ayo aphantsi kunye nobunzima, i-LDPE yokusebenza kakuhle kunye neendleko eziphantsi zenza ukuba ibalulekile kwizinto zokupakisha.

I-Polythylene (i-HDPE)
I-HDPE ipoliselwe phantsi koxinzelelo oluphantsi kwaye inesakhiwo esingaphezulu kwe-molersur, esikhokelela kwi-crystarnity ephezulu kunye nobunzima. Ukuxhathisa i-HDPE kukunganyangeki kwe-HDPE, ngelixa ikwanokungafihli. Ezi propati zenza ukuba i-HDPE isetyenziswe ngokubanzi kwimveliso yemibhobho, izikhongozeli, iibhotile kunye nezinto ezixhaphaza ngamachiza, phakathi kwezinye.

I-Liner Prenity Polythylene (LDDP)
I-LDDP yenziwa yi-colymering Polythylene enesixa esincinci se-copolymer molors (umz. I-Butene, i-hexene) kwingcinezelo ephantsi. Idibanisa ukuguquguquka kwe-ldpe ngamandla e-HDPE, ngelixa ibonisa ukungavisisani kwempembelelo ebalaseleyo kunye nokwaluphala.ldpe kuqhelekile ukwenza iifilimu ezinkulu, ezinje ngeefilimu, iifilimu zezolimo, njl.

Iindawo eziphambili zeplastiki
Ngenxa yokusebenza kunye nokusebenza okuphezulu kweplastiki, iindawo ezisetyenziswayo zibanzi kakhulu. Kumzi-mveliso wepakeji, iiplanga ze-PER zihlala zisetyenziselwa ukwenza iintlobo ezahlukeneyo zeefilimu zeplastiki, iingxowa kunye nezikhongozeli zokupakisha. Kwintsimi yemibhobho, i-HDPE isetyenziswa ngokuqhelekileyo kwimveliso yokuhambisa amanzi kunye nemibhobho yokuhambisa, imibhobho yegesi, njl njl. Kwimveliso yasekhaya, i-PAPSIY isetyenziselwa ukuvelisa iibhotile, izikhongozeli kunye nezinye iimveliso zeplastiki. Kwicandelo lezolimo, i-LDDE kunye ldpe baqhele ukwenza iifilimu zezolimo ukubonelela ngokhuseleko lwezityalo kunye nekhava yomhlaba.
Ukushwankathela
Yintoni iplastiki ye-PEP? Yinto eguquguqukayo, enoqoqosho kwaye isebenzise i-thermoplastic ngokubanzi. Ngokuqonda iintlobo ezahlukeneyo zeplasitiki zeplasitiki kunye neepropathi zabo, amashishini kunye nabathengi banokuzikhethela ngcono izinto ezifanelekileyo kwiimfuno zabo. Ukusuka kwiphakeji kunye nokutsala kwiimveliso zasekhaya, iplasitiki ye-PE idlala indima ebalulekileyo kububomi banamhlanje kunye nezibonelelo zayo ezizodwa. Ukuba udidekile xa ukhetha izixhobo zeplastiki, sinethemba lokuba eli nqaku linokukubonelela ngolwazi olubalulekileyo lokujonga.
