Masiqale sijonge imvelaphi yabo kunye nomqolo (isakhiwo semolekyuli). I-LDPE (i-polyethylene yoxinaniso oluphantsi): Njengomthi ochumileyo! Ikhonkco layo leemolekyuli linamasebe amaninzi amade, okukhokelela kwisakhiwo esikhululekile, esingaqhelekanga. Oku kubangela uxinano oluphantsi (0.91-0.93 g/cm³), olona luthambileyo, kwaye lubhetyebhetye kakhulu. I-HDPE (i-polyethylene ephezulu yoxinaniso): Njengamajoni ngokulandelelana! Itsheyina layo lemolekyuli linamasebe ambalwa kakhulu, nto leyo ebangela ukuba kubekho umgca olungelelanisiweyo nolungeleleneyo. Oku kuyinika obona bunzima buphezulu (0.94-0.97 g/cm³), obona bulukhuni, kwaye bunamandla. I-LLDPE (i-polyethylene yoxinaniso olusezantsi): Inguqulelo "evelisiweyo" ye-LDPE! Umqolo wayo umgca (njenge-HDPE), kodwa unamasebe amafutshane asasazwe ngokulinganayo. Ubuninzi bayo buphakathi kwezi zimbini (0.915-0.925 g/cm³), ukudibanisa ukuguquguquka okuthile ngamandla aphezulu.
IsiShwankathelo sokuSebenza esiPhambili: I-LDPE: Ithambile, ayifihli, kulula ukusetyenzwa, kwaye ixabiso eliphantsi ngokubanzi. Nangona kunjalo, inengxaki yokuqina, ukuqina, kunye nokuxhathisa ubushushu, nto leyo eyenza ukuba igqobhozwe lula. LLDPE: Eyona inzima! Inika impembelelo ekhethekileyo, ukukrazula, kunye nokumelana nokugqobhoza, ukusebenza kakuhle kobushushu obuphantsi, kunye nokuguquguquka okuhle, kodwa yomelele kune-LDPE. Ukungafihli kunye neepropathi zesithintelo ziphezulu kune-LDPE, kodwa ukusetyenzwa kufuna isilumkiso. I-HDPE: Eyona nto inzima! Inika amandla aphezulu, ubungqongqo obuphezulu, ukuxhathisa okugqwesileyo kweekhemikhali, ukumelana nobushushu obulungileyo, kunye nezona mpawu zintle zokuthintelwa. Nangona kunjalo, inengxaki yokuguquguquka okungalunganga kunye nokungafihli okuphantsi.
Isetyenziswa phi? Kuxhomekeke kwisicelo!
Izicelo ze-LDPE zibandakanya: iingxowa zokupakisha ezahlukeneyo eziguquguqukayo (iingxowa zokutya, iingxowa zesonka, iingxowa zempahla), ukusonga iplastiki (kwindlu kunye nosetyenziso oluthile lwezorhwebo), izitya eziguquguqukayo (ezifana neebhotile zokukhama zobusi kunye neketchup), ukugquma ucingo kunye nentambo, iinxalenye ezibunjiweyo zenaliti ekhaphukhaphu (ezifana ne-bottle cap liners kunye nezinto zokudlala), kunye ne-coatings cartoning (mi).
Amandla e-LLDPE abandakanya: iifilimu ezisebenza kakhulu ezifana ne-stretch wrap (okufuneka ube nayo kwi-packaging ye-industrial), iingxowa zokupakisha ezinzima (zokutya kunye nesichumisi), iifilimu ze-mulch yezolimo (ezincinci, eziqinileyo, kunye nezihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala khona. Isitofu esibunjiweyo samalungu afuna ukomelela okuphezulu abandakanya imigqomo, izivalo, kunye nezikhongozeli ezinodonga olucekethekileyo. Iintambo zombhobho kunye nejacket yekhebula nazo ziyasetyenziswa.
Amandla e-HDPE aquka: izikhongozeli ezomeleleyo ezifana neebhotile zobisi, iibhotile zokucoca, iibhotile zamayeza, kunye nemiphanda emikhulu yeekhemikhali. Imibhobho kunye nezixhobo ziquka imibhobho yamanzi (amanzi abandayo), imibhobho yegesi, kunye nemibhobho yemizi-mveliso. Iimveliso ezingenanto ziquka amagubu e-oyile, izinto zokudlala (ezifana neebhloko zokwakha), kunye neetanki zamafutha emoto. Iimveliso ezibunjiweyo zesitofu ziquka iibhokisi zenguqu, iipalethi, iikepusi zeebhotile, kunye nezinto eziyimfuneko zemihla ngemihla (izitya zokuhlambela nezitulo). Ifilimu: Iibhegi zokuthenga (eziqinileyo), iibhegi zemveliso, kunye neebhegi zeT-shirt.
Isikhokelo sokukhetha isivakalisi esinye: Ngaba ujonge iingxowa ezithambileyo, ezicacileyo, nezingabizi kakhulu/ifilimu? —————LDPE. Ngaba ujonge ifilim eqine kakhulu, ekwaziyo ukukrazula, kunye ne-puncture, okanye efuna ubunzulu bobushushu obuphantsi? —LLDPE (ingakumbi kwipakethe enzima kunye nefilimu eyoluliweyo). Ngaba ujonge iibhotile eziqinileyo, eziqinileyo, ezikwaziyo ukumelana neekhemikhali/imiphanda/imibhobho yolwelo? —HDPE
