Tee e nang le mekotla e ntlafetse ka potlako ka lebaka la melemo ea eona ea "bongata, bohloeki, boiketlo le lebelo", 'me' maraka oa tee e nang le mekotla lefatšeng ka bophara o bontša mokhoa oa kholo e potlakileng.
Jwalo ka thepa ya ho paka bakeng sa mekotla ya tee,pampiri ea ho sefa teeHa ea lokela ho netefatsa feela hore metsoako e sebetsang ea tee e ka namela ka potlako sophong ea tee nakong ea ts'ebetso ea ho ritela, empa hape e thibela phofo ea tee ka mokotleng hore e se ke ea kenella sophong ea tee. Kamora lilemo tsa nts'etsopele, thepa ea pampiri ea sefe ea tee e fetohile butle-butle ho tloha ho gauze, pampiri ea sefe, nylon, PET, PVC, PP le lisebelisoa tse ling ho ea ho faeba ea poone.
Faeba ea poone, e tsejoang hape e le faeba ea polylactic acid (PLA), e nkiloe mehloling ea limela tse nchafatsoang joalo ka poone, litapole le joang ba lijalo. E na le ho lumellana hantle le ho bola ha lintho tse phelang, thepa ea ho loantša libaktheria le ho hema habonolo. E ke ke ea sebelisoa feela ho etsa mekotla ea tee e sa lohiloeng e bolang, empa hape e ka sebelisoa tšimong ea ho etsa pampiri e metsi ho hlahisa pampiri ea ho paka lijo joalo ka mekotla ea tee, mekotla ea kofi, lepampiri ea sefe.
Kahoo, ha re shebana le litšobotsi tsa ts'ebetso ea thepa ka boeona, melemo e meholo ea ho sebelisa faeba ea PLA ho etsa pampiri e metsi ke efe?
1. Thepa ke ea tlhaho 'me e ka kopana le lijo
Thepa e tala ea fiber ea polylactic acid e tsoa mehloling ea limela tse nchafatsoang. Jwalo ka thepa e netefalitsoeng ea polokeho ea lijo, fiber ea polylactic acid e ka sebelisoa haholo mefuteng e fapaneng ea lijo, meriana, le lits'ebetsong tse ling tsa pampiri ea lapeng tse batloang haholo. Ha re nka tšebeliso ea mekotla ea tee le pampiri ea sefe ea kofi e le mohlala, ho li kenya ka kotloloho metsing a chesang ntle le pula ea polasetiki kapa lintho tse ling tse kotsi ho bonolo ho 'mele oa motho.
2. Ho bola ha lintho tse phelang
Ha re nka tšebeliso ea mekotla ea tee mohlala, palo e kholo ea mekotla ea tee e lahloang e jeoa lefatšeng ka bophara letsatsi le letsatsi. Mekotla ea tee e entsoeng ka thepa ea setso e na le potoloho e telele haholo ea ho senyeha, e leng se tla tlisa khatello e kholo tikolohong ea tlhaho. Leha ho le joalo, mekotla ea tee kapa lihlahisoa tse ling tse entsoeng ka thepa ea polylactic acid li na le bokhoni bo botle ba ho bola.
Lihlahisoa tsa lesela tse sa lohiloeng tse nang le faeba ea polylactic acid li ka bola ka botlalo hore e be carbon dioxide le metsi ke likokoana-hloko tse tikolohong ea tlhaho tse nang le mocheso le mongobo o itseng, joalo ka lehlabathe, seretse le metsi a leoatle. Litšila tsa lihlahisoa tsa polylactic acid li ka bola ka botlalo hore e be carbon dioxide le metsi tlas'a maemo a indasteri a ho etsa manyolo (mocheso oa 58 ℃, mongobo oa 98%, le maemo a likokoana-hloko) ka likhoeli tse 3-6; Ho tlatsa mobu libakeng tse tloaelehileng le hona ho ka senya nakong ea lilemo tse 3-5.
3. E ka kopanngoa le pulp ea lehong kapa likhoele tse ling tsa tlhaho bakeng sa tšebeliso
Hangata likhoele tsa asiti ea polylactic li tsoakoa ka tekanyo e itseng le likhoele tsa pulp ea lehong, likhoele tsa nano, jj. ho etsa pulp le pampiri. Asiti ea polylactic e bapala karolo haholo-holo ho kopanyeng le ho matlafatseng, ka ho hokahanya likhoele tse ling ka mocheso le mocheso ho fihlela morero oa ho foreimi le ho matlafatsa. Ho phaella moo, ka ho fetola karolelano ea slurry le mokhoa oa ho e lokisa, e ka fihlela litlhoko tse fapaneng tsa maemo a fapaneng.
4. Ho tlamahana ha mocheso ka ultrasound ho ka finyelloa
Ka ho sebelisa likhoele tsa polylactic acid ho etsa pulp le pampiri, ho kopana ha mocheso oa ultrasonic ho ka finyelloa tlhahisong e latelang, e leng se sa bolokeng basebetsi feela le ho fokotsa litšenyehelo, empa hape se ntlafatsang katleho ea tlhahiso.
5. Tshebetso ya ho sefa
Pampiri ea sefe ea tee e entsoeng ka faeba ea polylactic acid e na le ts'ebetso e ntle ea ho sefa le matla a mangata a metsi, e ka bolokang makhasi a tee le likaroloana tse ling tse tiileng ka katleho, ha e ntse e lumella tatso le monko oa tee ho kenella ka botlalo.
Ntle le pampiri ea ho sefa tee, fiber ea polylactic acid e ka boela ea sebelisoa pampiring ea ho sefa ea ho paka meriana ea setso ea Chaena, pampiring ea ho sefa ea kofi le pampiring e 'ngoe ea ho paka lijo.
