Ake siqale sibheke imvelaphi yabo kanye nomgogodla (isakhiwo samangqamuzana). I-LDPE (i-polyethylene enezinga eliphansi): Njengesihlahla esiluhlaza! Iketanga layo lamangqamuzana linamagatsha amaningi amade, okuholela ekwakhiweni okuxekethile, okungajwayelekile. Lokhu kubangela ukuminyana okuphansi kakhulu (0.91-0.93 g/cm³), okuthambile, nokuvumelana nezimo kakhulu. I-HDPE (i-polyethylene ephezulu kakhulu): Njengamasosha elandelana! Iketanga layo lamangqamuzana linamagatsha ambalwa kakhulu, okuphumela ekwakhiweni komugqa okupakishwe ngokuqinile futhi okuhlelekile. Lokhu kuyinikeza ukuminyana okuphezulu kakhulu (0.94-0.97 g/cm³), okunzima kakhulu, nokuqine kakhulu. I-LLDPE (i-polyethylene enomugqa ophansi): Inguqulo "eguquliwe" ye-LDPE! Umgogodla wayo uqondile (njenge-HDPE), kodwa unamagatsha amafushane asakazwe ngokulinganayo. Ukuminyana kwayo kuphakathi kokubili (0.915-0.925 g/cm³), kuhlanganisa ukuguquguquka okuthile namandla aphezulu.
Isifinyezo Sokusebenza Okubalulekile: I-LDPE: Ithambile, isobala, kulula ukuyicubungula, futhi ngokuvamile iphansi ngezindleko. Kodwa-ke, ihlushwa amandla aphansi, ukuqina, nokumelana nokushisa, okuyenza ibhoboze kalula. LLDPE: Okunzima kakhulu! Inikeza umthelela oyingqayizivele, ukudabuka, nokumelana nokubhoboza, ukusebenza okuhle kakhulu kwezinga lokushisa eliphansi, nokuguquguquka okuhle, kodwa iqinile kune-LDPE. Izinto zayo ezibonisa ngale kanye nezithiyo ziphakeme kune-LDPE, kodwa ukucubungula kudinga ukuqapha okuthile. I-HDPE: Enzima kakhulu! Inikeza amandla aphezulu, ukuqina okuphezulu, ukumelana namakhemikhali okuhle kakhulu, ukumelana nokushisa okuhle, kanye nezakhiwo ezinhle kakhulu zokuvimbela. Nokho, ihlushwa ukungaguquguquki kahle kanye nokungafihli lutho okuphansi.
Isetshenziswa kuphi? Kuya ngesicelo!
Izicelo ze-LDPE zifaka: izikhwama zokupakisha ezihlukahlukene eziguquguqukayo (izikhwama zokudla, izikhwama zesinkwa, izikhwama zezingubo), ukugoqa kwepulasitiki (kokusetshenziswa kwasendlini nokunye ukuhweba), iziqukathi eziguquguqukayo (njengamabhodlela okukhama oju neketchup), ukufakwa kwentambo nokufakwa kwekhebula, izingxenye ezibunjiwe zomjovo ezingasindi (njengezivalo zamabhodlela namathoyizi), nezimbotshana ze-cartoning (milk).
Amandla e-LLDPE ahlanganisa: amafilimu asebenza kahle kakhulu afana nokugoqa okunwetshiwe (okufanele ube nakho kokupakishwa kwezimboni), izikhwama zokupakisha ezisindayo (zokondla nomanyolo), amafilimu e-mulch yezolimo (amancane, aqinile, futhi ahlala isikhathi eside), izikhwama ezinkulu zikadoti (ezingephuki), nezingqimba ezimaphakathi zamafilimu ayinhlanganisela. Izingxenye ezibunjwe ngomjovo ezidinga ukuqina okuphezulu zihlanganisa imiphongolo, izivalo, neziqukathi ezinezindonga ezincane. Izintambo zamapayipi kanye ne-cable jacketing nazo ziyasetshenziswa.
Amandla e-HDPE ahlanganisa: iziqukathi eziqinile njengamabhodlela obisi, amabhodlela okuhlanza, amabhodlela emithi, nemiphongolo emikhulu yamakhemikhali. Amapayipi nokufakwa kuhlanganisa amapayipi amanzi (amanzi abandayo), amapayipi egesi, namapayipi ezimboni. Imikhiqizo engenalutho ihlanganisa izigubhu zikawoyela, amathoyizi (njengamabhulokhi wokwakha), namathangi kaphethiloli emoto. Imikhiqizo ebunjwe ngomjovo ihlanganisa amabhokisi entengo, amaphalethi, izikepisi zamabhodlela, kanye nezidingo zansuku zonke (izitsha zokugezela nezihlalo). Ifilimu: Izikhwama zokuthenga (eziqinile), izikhwama zemikhiqizo, nezikhwama zezikibha.
Umhlahlandlela wokukhetha umusho owodwa: Ufuna izikhwama/ifilimu ethambile, esobala, futhi engabizi? —————LDPE. Ingabe ufuna ifilimu eliqine kakhulu, elimelana nezinyembezi, nelivikela ukubhoboza, noma elidinga ukuqina kwezinga lokushisa eliphansi? I-LLDPE (ikakhulukazi yokupakisha okunzima kanye nefilimu elula). Ingabe ufuna amabhodlela/imiphongolo/amapayipi oketshezi aqinile, aqinile, amelana namakhemikhali? - I-HDPE
