Izintambo, izintambo, amapayipi, amapayipi, namaphrofayili kuyizicelo ezimbalwa ze-PE. Izicelo zamapayipi zisukela emapayipini amnyama anezindonga eziwugqinsi ongu-48-inch-diameter amapayipi ezimboni nasemadolobheni kuya kumapayipi amancane aphuzi awela igesi yemvelo. Ukusetshenziswa kwepayipi elikhulu lodonga elingenalutho elinobubanzi obuyindilinga esikhundleni semigqa yendle nemisele yesiphepho eyenziwe ngokhonkolo kukhula ngokushesha.
I-Thermoforming namashidi
Amapholisa amaningi amakhulu epikiniki afaka phakathi amalayini e-thermoformed akhiwe i-PE, anikeza ukuqina, ukukhanya, nokuqina. Amafenda, amathangi okugcina amathangi, onogada bamapani, amakhreyithi okuthumela impahla, namathangi kuyizibonelo zeshidi elengeziwe nezinto ezine-thermoformed. I-mulch noma i-pool bottoms, encike ekuqina kwe-MDPE, ukumelana namakhemikhali, nokungangenisi emanzini, kuyizinhlelo ezimbili ezibalulekile futhi ezinwetshwa ngokushesha zeshidi.
Ukufutha isikhunta
I-United States ithengisa ngaphezu kwengxenye eyodwa kwezintathu yayoI-HDPEyokubumba igalelo. Zisukela eziqandisini ezincane, iziqandisi ezinkulu, amathangi kaphethiloli ezimoto, namabhodlela kuya emabhodleleni e-bleach, amafutha emoto, okokuhlanza, ubisi namanzi amile. Amamaki afanayo angasetshenziselwa izinhlelo zokusebenza zeshidi kanye ne-thermoforming njengoba amandla ancibilikayo, i-ES-CR, nokuqina kuyizimpawu ezihlukile zamamaki okubumba.
umjovo
Iziqukathi ezincane (ezingaphansi kuka-16oz) zivame ukukhiqizwa kusetshenziswa i-blow molding yokupakisha ama-shampoos, izimonyo, nemithi kadokotela. Inzuzo yale ndlela ukuthi amabhodlela aqediwe anqunywa ngokuzenzakalelayo, ngokungafani nezinqubo zokubumba ezijwayelekile ezidinga imisebenzi yokuqeda ngemva kokuqeda. Nakuba amanye amamaki e-MWD amancane esetshenziswa ukuze kuthuthukiswe ukupholisha kwendawo, amamaki e-MWD aphakathi nendawo ukuya kububanzi asetshenziswa ngokujwayelekile.
ukubumba umjovo
Ingxenye eyodwa kwezinhlanu kwezikhiqizwa kuleliI-HDPEisetshenziswa ezinhlelweni ezisukela kumakani angu-5-gsl kuya ezinkomishini zesiphuzo ezinezindonga ezincane ezisebenziseka kabusha. Kunamabanga aphansi oketshezi olunamanzi anokuqina kanye namabanga aphezulu oketshezi olunamandla, futhi amamaki okubumba umjovo ngokuvamile anenkomba yokuncibilika engu-5 ukuya ku-10. Impahla enezindonga ezincane kanye nokupakishwa kokudla, ukudla okuqinile, okuhlala isikhathi eside namakani opende, kanye nezicelo ezinobuhle obukhethekile. ukumelana nokuqhekeka kwengcindezi yezemvelo, amathini kadoti angamalitha angama-90 kanye namathangi kaphethiloli wemoto amancane, ezinye izinto ezisetshenziswayo kule nto.
ukubumba okuphendukayo
Uma izinto zicutshungulwa kusetshenziswa lobu buchwepheshe, zivame ukuchotshozwa zibe yimpushana bese ziyancibilika futhi zigeleze ngomjikelezo oshisayo. I-Rotomolding isebenzisa amakilasi e-PE axhumekeka kalula futhi ajwayelekile. Inkomba yayo yokuncibilika ngokuvamile isuka ku-3 iye ku-8, futhi ukuminyana kwayo okujwayelekile kwe-MDPE/I-HDPEngokuvamile iphakathi kuka-0.935 no-0.945g/CC ene-MWD encane, okunikeza umkhiqizo umthelela ophezulu kanye ne-warpage encane. Amabanga aphezulu e-MI awafaneleki ngoba awanawo umthelela ohlosiwe wezimpahla ze-rotomold kanye nokumelana nokuqhekeka kwengcindezi yendawo.
Izicelo ze-rotomoulding yokusebenza okuphezulu zisebenzisa izimfanelo ezikhethekile zamamaki ayo ahlanganayo ngamakhemikhali. Lawa mabanga anokumelana okuvelele kokucindezeleka kwemvelo kanye nokuqina phakathi nesigaba sokuqala somjikelezo wokubumba lapho egeleza kahle. ukumelana nesimo sezulu kanye nokuhuzuka. Iziqukathi ezinkulu ezisukela ku-20,000-gallon amathangi okugcina ezolimo kuya ku-500-gallon amathangi okugcina asetshenziselwa ukuthwala amakhemikhali ahlukahlukene afaneleka ngokuphelele i-PE exhumeke kakhulu.
ifilimu
Ukucutshungulwa kwefilimu okufuthwe okuvamile noma ukucutshungulwa kwe-flat extrusion ngokuvamile kusetshenziswa ekucubunguleni ifilimu ye-PE. Iningi lama-PE asetshenziselwa amafilimu; izinketho zihlanganisa i-linear low density PE (LLDPE) noma i-PE (LDPE) yenhloso evamile. Lapho kudingeka ukunwebeka okukhulu kanye nezimfanelo ezinhle kakhulu zokuthibela, amamaki efilimu ye-HDPE ngokuvamile asetshenziswa. Isibonelo, ifilimu ye-HDPE ivamise ukusetshenziswa ezikhwameni zesuphamakethe, emaphaketheni okudla, nasezikhwameni zemikhiqizo.
