Libaka tse lebōpong la leoatle naheng ea rona li na le libaka tse ntle tsa tikoloho le mehloli e ikhethang ea bohahlauli ba lihlekehleke. Haholo-holo Qingdao, toropo e ntle ea lebopong la leoatle moo k'hamphani ea rona e leng teng, ka nts'etsopele ea bohahlauli ba boikhathollo ba leoatle le temo ea likepe, temo ea litlhapi tse emisitsoeng ka metsing a leoatle e hlahile. Lebokose la ho emisoa ka metsi a leoatle ke mofuta oa sethala se phaphametseng se ka beoang maoatleng a bulehileng hanyane ka tšusumetso e fokolang ea maholiotsoana a linako tsa selemo. Ho latela litlhoko tse fapaneng, le ka sebelisoa bakeng sa ho tšoasa litlhapi tsa boikhathollo, boema-kepe ba batšoasi ba litlhapi, bohahlauli le ho bona libaka, temo ea litlhapi tse tebileng ka metsing a leoatle, jj.
Letlooa la ho emisa metsi a leoatle lea le amohela Liphaephe tsa HDPE e le foreimi ea letlooa 'me e fana ka tšehetso ea ho phaphamala. Bokaholimo bo na le lipedali tsa leoatleng ho etsa sebopeho sa sethala, seo batho ba ka tsamaeang ho sona ka bolokolohi.
Pendele ea leoatleng ke karolo ea bohlokoa ea letlooa la ho tšoasa litlhapi ka metsing a leoatle. Ka nts'etsopele ea indasteri le litlhapi, tlhoko ea 'maraka e ntse e eketseha,' me tlhoko ea 'maraka ea lintho tse joalo e ntse e eketseha. lihlahisoa tsa extrusion le yona e ntse e hola. Mofuta ona wa pedal ya lewatle ha o bonolo feela hore batho ba tsamaye ho wona, empa hape o sireletsa tikoloho haholo.
Profaele ea pedal ea leoatleng extrusion mola, temo ea metsing ke mokhoa oa tlhahiso oa ho ikatisa le ho jala liphoofolo le limela tsa moruo oa leoatle ka ho sebelisa maoatle a sa tebang, mabōpo a leoatle, likou, le matamo a koetsoeng le libaka tse ling tsa leoatle. Ke e 'ngoe ea litsela tsa bohlokoa tsa hore batho ba sebelise mehloli ea baeloji ea leoatle ka tsela e tobileng le ho nts'etsapele indasteri ea ho tšoasa litlhapi tsa leoatleng.
Selelekela ho Lisebelisoa tsa ho Ntša Mabanta a Metsing tsa PE
The Mohala oa tlhahiso ea extrusion ea polasetiki ea PE E ntshetswa pele ke khamphani ya rona e etseditswe ho fihlela ditlhoko tsa tlhahiso ya dipedali tsa lewatle, ebe e kopanya thepa e tala mme e di dumella ho kena ka hara sekurufu, mme e ntshe pedali e neng e entswe pele ka hlobo. E phodiswa mme e boptjwe ka hara tanka ya metsi a phodisang, mme qetellong e hulelwa mochining wa ho seha ke terekere ho phethela mosebetsi wa ho phethela. Mohala wa rona wa ho ntsha o ka hlahisa dipedali tsa lewatle hantle haholo, ka tshebetso e tsitsitseng ya tlhahiso, tekanyo e phahameng ya boiketsetso, tshebediso e tlase ya matla, bokgoni bo phahameng ba tlhahiso, mme dipedali tsa lewatle tse hlahisitsweng di boleng bo botle.
Selelekela sa Melemo ea Lihlahisoa tsa Extrusion tsa Lipedele tsa Leoatle
Mohala oa ho ntša pedal ea temo ea metsing o hlahisoang ke PE E sebelisa polyethylene e nang le boima bo phahameng ba limolek'hule (HDPE) e le thepa e tala, e entsoeng ka ts'ebetso ea extrusion 'me e sebelisoa litsing tse fapaneng tsa metsi joalo ka likepe, marokho a phaphametseng le liforomo. Melemo ea eona e kenyelletsa: ke thepa e matlafalitsoeng e thibelang mafome, e thibelang ho hoama le e thibelang mahlaseli a letsatsi; ha e senyehe ke metsi a leoatle, lik'hemik'hale, lintho tse sebetsang, matheba a oli le lintho tse phelang metsing; ha e na tšilafalo 'me ha e senye tikoloho. Mohala oa extrusion oa pedal ea leoatle o khetholloa ka boleng bo tšepahalang, litheko tse ntle, thepa e mosa tikolohong, meralo e mecha, libopeho tse fapaneng, le lits'ebeletso tsa boleng bo holimo.
Tšebeliso e sebetsang maemong a tlhahiso
1) Setsi sa tlhahiso bakeng sa lihlahisoa tsa ho ntša pedal ea leoatleng: Ho khothalletsoa hore e be libakeng tse lebōpong la leoatle. Ha ho nahanoa ka thepa le boholo ba tlhahiso, e lokela ho ba haufi le lebōpo la leoatle kamoo ho ka khonehang. Haholo-holo libakeng tse ling, lihlahisoa li sebelisoa ka ho toba ke leoatle ka mor'a hore li hlahisoe.
2) Tšebeliso ea lihlahisoa tsa ho ntša pedal ea leoatleng: Li sebelisoa haholo-holo bakeng sa temo ea metsing e tebileng le e sa tebang, joalo ka temo ea li-croakers tse tšehla, li-scallops le li-kelps.
3) Menyetla ea lihlahisoa tsa ho ntša pedal ea leoatleng: Hona joale, ka lebaka la moralo oa naha, haholo-holo khothatso ea hore batšoasi ba litlhapi ba bangata ba kopanele temong e tala ea metsing, mmuso o fana ka lithuso tse kholo tsa leano ntlheng ena. Leha ho le joalo, liphesente tsa lithuso lia fapana ho latela libaka tse fapaneng.
4) Ho kenya le ho sebelisa lihlahisoa tsa ho ntša pedal ea leoatleng: Ho latela sebaka le ts'ebeliso, e entsoe haholo-holo ka lipedal tsa leoatleng tsa PE + liphaephe tsa PE + li-floats tse se nang letho tsa PE. Ebe u li lokisa ka li-pedal tse chesang tse qhibilihang + li-screw. Ho ea ka litlhoko tsa batšoasi ba litlhapi, hlahisa lihlahisoa tsa ho ntša pedal ea leoatleng tsa boholo le litlhaloso tse fapaneng.
Ka dilemo tse ka bang 20 indastering ya disebediswa tsa extrusion tse bohlale, o bile le mesebetsi ya bohlokwa ho Jwell Machinery, ho kenyeletswa le Motsamaisi Kakaretso le Modulasetulo ya Potolohang. Ho tloha ka 2024, o laotse makala a mangata a ka tlase, a kganna katoloso ya kgwebo le ntlafatso ya diindasteri, ha a ntse a etella pele boqapi tlhahisong e bohlale le kgolo ya lefatshe.
