Izintambo, izintambo, amapayipi, amapayipi, kanye namaphrofayili kumane kuyizicelo ezimbalwa ze-PE. Izicelo zamapayipi zisukela kumapayipi amnyama anobubanzi obungu-48 intshi anombala obanzi wamapayipi ezimboni nawasemadolobheni kuya kumapayipi amancane aphuzi anqamula ingxenye yegesi yemvelo. Ukusetshenziswa kwamapayipi amakhulu anobubanzi obungenalutho esikhundleni semigqa yendle kanye nemisele yamanzi emvula eyenziwe ngokhonkolo kukhula ngokushesha.
Ukulungisa ukushisa kanye namashidi
Ama-cooler amaningi amakhulu e-picnic afaka ama-liner afakwe i-thermoformed akhiwe yi-PE, enikeza ukuqina, ukukhanya, nokuqina. Ama-Fenders, ama-liner amathangi, ama-pan guards, ama-shipping crates, nama-tank ayizibonelo zezinto ezengeziwe zeshidi kanye ne-thermoformed. Ama-mulch noma ama-pool bottom, ancike ekuqineni kwe-MDPE, ukumelana namakhemikhali, kanye nokungangeni kwamanzi, yizinhlelo ezimbili ezibalulekile nezikhula ngokushesha zeshidi.
Ukufutha isikhunta
I-United States ithengisa ngaphezu kwengxenye eyodwa kwezintathu yayoI-HDPEzokubopha ngomshini wokufaka umoya. Zisukela eziqandisini ezincane, eziqandisini ezinkulu, emathangini kaphethiloli ezimoto, kanye namathini kuya emabhodleleni e-bleach, uwoyela wemoto, insipho, ubisi, namanzi anganyakazi. Amabanga afanayo angasetshenziswa ezinhlelweni zokufaka ishidi kanye ne-thermoforming njengoba amandla okuncibilikisa, i-ES-CR, kanye nokuqina kuyizimpawu ezihlukile zamabanga okubopha ngomshini wokufaka umoya.
umjovo
Izitsha ezincane (ezingaphansi kuka-16oz) zivame ukukhiqizwa kusetshenziswa i-blow molding yokupakisha ama-shampoo, izimonyo, kanye nemithi kadokotela. Inzuzo yale ndlela ukuthi amabhodlela aqediwe anqunywa ngokuzenzakalelayo, ngokungafani nezinqubo ezijwayelekile ze-blow molding ezidinga imisebenzi yangemva kokuqeda. Nakuba amanye amamaki amancane e-MWD asetshenziswa ukuthuthukisa ukupholisha kwendawo, amamaki aphakathi kuya kwabanzi e-MWD avame ukusetshenziswa.
ukubumba umjovo
Ingxenye eyodwa kwezinhlanu zemikhiqizo eyenziwe ekhayaI-HDPEisetshenziswa ezinhlotsheni ezisukela kumathini angu-5-gsl kuya ezinkomishini zeziphuzo ezinodonga oluncane ezingasetshenziswa kabusha. Kunezinhlobo eziphansi zokugeleza koketshezi ezinokuqina kanye namazinga aphezulu okugeleza koketshezi anokusebenza kahle, kanti izinhlobo zokubumba ngomjovo zivame ukuba nenkomba yokuncibilika engu-5 kuya ku-10. Izimpahla ezinodonga oluncane kanye nokupakishwa kokudla, amathini okudla aqinile, ahlala isikhathi eside, kanye nezinhlelo zokusebenza ezinokumelana okungavamile nokuqhekeka kokucindezeleka kwemvelo, njengamathini kadoti angamalitha angu-90 kanye namathangi kaphethiloli amancane, ezinye zezinto ezisetshenziswayo zalokhu.
ukubumba okujikayo
Uma izinto zicutshungulwa kusetshenziswa lobu buchwepheshe, zivame ukuchotshozwa zibe yimpuphu bese zincibilikiswa bese zigeleza emjikelezweni wokushisa. I-Rotomolding isebenzisa amakilasi e-PE axhumekayo kanye nenhloso ejwayelekile. Inkomba yayo yokuncibilika ivame ukusuka ku-3 kuya ku-8, kanye nobuningi bayo obujwayelekile be-MDPE/I-HDPEngokuvamile iphakathi kuka-0.935 no-0.945g/CC ene-MWD encane, okwenza umkhiqizo ube nomthelela omkhulu kanye nokuphambana okuncane. Amamaki aphezulu e-MI ngokuvamile awafaneleki ngoba awanayo ithonya elihlosiwe lezimpahla ezihlanganisiwe kanye nokumelana nokuqhekeka kokucindezeleka kwemvelo.
Izicelo ze-rotomoulding esebenza kahle zisebenzisa izimfanelo ezikhethekile zamazinga ayo axhumekayo ngamakhemikhali. Lawa mabanga anokumelana okuvelele kokuqhekeka kokucindezeleka kwemvelo kanye nokuqina ngesikhathi sesigaba sokuqala somjikelezo wokubumba lapho egeleza kahle. Amelana nesimo sezulu kanye nokuguguleka. Izitsha ezinkulu ezisukela emathangini okugcina ezolimo angamalitha angu-20,000 kuya kumathangi okugcina angamalitha angu-500 asetshenziselwa ukuthwala amakhemikhali ahlukahlukene zifaneleka kahle kakhulu kwi-PE exhumekayo.
ifilimu
Ukucutshungulwa kwefilimu okujwayelekile okuphehliwe noma ukucutshungulwa kwe-flat extrusion kuvame ukusetshenziswa ekucutshungulweni kwefilimu ye-PE. Iningi lama-PE lisetshenziselwa amafilimu; izinketho zifaka phakathi i-linear low density PE (LLDPE) noma i-general-purpose low density PE (LDPE). Lapho kudingeka ukwelulwa okuhle kanye nezimfanelo ezinhle kakhulu zokuvimbela, amazinga efilimu ye-HDPE avame ukusetshenziswa. Isibonelo, ifilimu ye-HDPE ivame ukusetshenziswa ezikhwameni zesuphamakethe, ekupakishweni kokudla, kanye nasezikhwameni zemikhiqizo.
