Loluphi uhlobo lweplastiki iPE? Inkcazo eneenkcukacha yeentlobo, iipropati kunye nokusetyenziswa kwe-polyethylene (PE)
Yintoni iplastiki ye-PE?
"Yintoni iplastiki ye-PE?" Lo mbuzo uvame ukubuzwa, ngakumbi kumashishini ekhemikhali kunye nemveliso.PE, okanye i-polyethylene, i-thermoplastic eyenziwe yi-polymerising ethylene monomer. Njengenye yeeplastiki eziqhelekileyo, i-PE iyaziwa ngokusetyenziswa kwayo ngeendlela ezahlukeneyo kunye noluhlu olubanzi lwezicelo. Ixabiso layo eliphantsi, iplastiki ephezulu kunye nokuzinza kweekhemikhali kuyenza ibe yinto eyimfuneko kwishishini lanamhlanje.
Iindidi zeePlastiki zePE
Iiplastiki zePolyethylene (PE) zihlulwe zibe ziindidi ezintathu eziphambili: i-polyethylene ephantsi (i-LDPE), i-polyethylene ephezulu (i-HDPE) kunye ne-linear low-density polyethylene (LLDPE).
IPolyethylene yoXinano oluPhantsi (LDPE)
I-LDPE yi-polyethylene enesakhiwo esihlakazekile ngakumbi, okubangela ukuxinana okuphantsi. Iguquguquka kwaye iyabonakala kwaye isetyenziswa ngokuqhelekileyo ekwenzeni iingxowa zeplastiki, ifilimu yokutya kunye nezinto zokupakisha eziguquguqukayo.

Uxinaniso oluPhezulu lwePolyethylene (HDPE)
I-HDPE inesakhiwo esingqongqo se-molecular kune-LDPE, okubangelwa ukuxinana okuphezulu kunye nokushisa okukhulu kunye nokumelana nempembelelo.I-HDPE isetyenziswa ngokuqhelekileyo ekuveliseni iimveliso zeplastiki eziqinileyo ezisetyenziswa kubomi bemihla ngemihla, ezifana neebhotile zobisi, imibhobho kunye namathoyizi.

I-Linear Low Density Polyethylene (LLDPE)
I-LLDPE idibanisa ukuguquguquka kwe-LDPE kunye namandla e-HDPE kunye nokwelula okulungileyo kunye nokuchasana nokukrazula. Ihlala isetyenziselwa ukwenza iifilimu ezinzima, ezifana neefilimu zokupakisha zezolimo kunye nezoshishino.

Iipropati zeplastiki ye-PE
Ukuqonda "iyiphi iplastiki ye-PE" idinga ukujonga nzulu kwiimpawu zayo eziphathekayo. I-polyethylene ineempawu ezilandelayo zokuhlukanisa:
Ukuzinza kweekhemikhali okugqwesileyo
I-polyethylene inokumelana kakuhle neekhemikhali ezininzi ezinjengeeasidi, iialkali kunye neetyuwa. Ngenxa yesi sizathu, izinto ze-PE zihlala zisetyenziswa kwizikhongozeli zeekhemikhali kunye nemibhobho.

Ukuchasana kwempembelelo ephezulu
Zombini i-polyethylene ephezulu kunye ne-low-density-density high-density resistance resistance, ezenza zibe zibalaseleyo ekupakishweni nasekugcinweni.

Ukugquma kombane
I-Polyethylene yi-insulator yombane egqwesileyo kwaye isetyenziswa rhoqo kwisigqubuthelo sangaphandle seengcingo kunye neentambo zokuqinisekisa ukusebenza ngokukhuselekileyo kwezixhobo zombane.

Ukusetyenziswa kweeplastiki ze-PE
Uluhlu olubanzi lwezicelo ze-polyethylene luphendula ngokupheleleyo umbuzo "Yintoni i-PE? Ngenxa yeempawu zayo ezahlukeneyo, izinto ze-PE zithatha indawo ebalulekileyo kwinani lamashishini.
Ukupakishwa
I-Polyethylene idlala indima ebalulekileyo kwishishini lokupakisha, ngokukodwa kwindawo yokupakisha okuguquguqukayo, apho izikhwama zeplastiki ze-PE kunye neefilimu zizona zicelo eziqhelekileyo ze-PE kwimpilo yemihla ngemihla.

Ukwakhiwa kunye nokuBopha
I-polyethylene ephezulu yoxinaniso (HDPE) isetyenziswa ngokubanzi kwishishini lokwakha imibhobho, unikezelo lwamanzi kunye nemibhobho yokuhambisa igesi ngenxa yeempawu zayo zokugqwala kunye nokumelana noxinzelelo.

IiMpahla zabaThengi kunye nezeKhaya
Iiplastiki ze-PE zikwasetyenziswa kwiimveliso zabathengi bemihla ngemihla ezifana namathoyizi, iimpahla zasekhaya kunye nezikhongozeli zokugcina. Ezi mveliso azikhuselekanga kuphela kwaye azinatyhefu kuphela, kodwa zinokuphinda zisetyenziswe ukunciphisa ukungcoliseka kwendalo.

Ukuqukumbela
Ukushwankathela, impendulo yombuzo othi "Yintoni iplastiki ye-PE?" Impendulo yalo mbuzo ibandakanya ukuhlukahluka kwezinto ze-polyethylene kunye noluhlu olubanzi lwezicelo. Njengesixhobo seplastiki esizinzile, esithambileyo kunye nexabiso eliphantsi, i-PE idlala indima ebalulekileyo kuzo zonke iinkalo zoluntu lwanamhlanje. Ukuqonda iintlobo zayo ezahlukeneyo kunye neepropathi kunokusinceda ukuba sisebenzise kakuhle esi sixhobo ukuqhubela phambili ishishini kunye nomgangatho wokuphila.
