Kamoo Twin Screw Extruders e Sebetsang Kateng

Ho Fepa le ho Fetisa Lintho Tse Bonahalang

Ea pele, o lokisetsa lisebelisoa tsa hau tse tala. Etsa bonnete ba hore li omme ebile li hloekile. Sena se thusa ho emisa mathata hamorao. U kenya lisebelisoa ka har'a extruder ka feeder. Li-feeders tsa volumetric li lekanya ka molumo. Li-feeders tsa gravimetric li lekanya ka boima ba 'mele 'me li nepahetse haholoanyane. Ho fepa ka tekanyo e lekanang nako le nako ke habohlokoa bakeng sa molemo extrusion ea polasetiki.

Li-screws tse ka hare li hula thepa pele. Moralo oa screw le barrel o thusa ho tsamaisa lintho hantle. Meralo ea li-screw tsa intermeshing e emisa ho lutla mme e sebetse betere. Karolo ea lijo e na le li-grooves le pholileng ho thusa ho fepa lintho tse ngata. O ka laola lebelo la metsi le screw ho boloka lintho li tsitsitse. Tafole e ka tlase e bontša se amang thepa ea ho fepa le ho falla:

Keletso: Kamehla hlahloba phepelo ea hau 'me u netefatse hore lisebelisoa li omme. Sena se emisa mathata a phepelo mme se boloka ts'ebetso ea hau e le bonolo.

Ho kopanya le ho kopanya

Ha thepa e kena ka har'a li-screw, ho qala ho kopanya. The mafahla a sekoti extruder e sebelisa likurufu tse peli ho kopanya le ho duba. Sena se kopane hantle ho feta screw extruder e le 'ngoe. O ka eketsa li-fillers, mmala, kapa litlatsetso libakeng tse fapaneng. Sena se etsa hore li-scruder tse mafahla li be ntle bakeng sa ho kopanya polymer.

Li-screws li na le likarolo tse khethehileng tse kang li-blocks blocks le likarolo tse kopanyang. Tsena li qhekella likotoana le ho hasanya lintho. U fumana motsoako o boreleli, e hlokahalang bakeng sa extrusion e ntle ya polasetiki. Tafole e ka tlase e bapisa ho kopanya le ho kopanya:

U ka sebelisa extruder bakeng sa mesebetsi e mengata, joalo ka ho kopanya polymer le ho e sebelisa hape. Moralo oa screw o o lumella ho fetola matla a ho kopanya le nako. Sena se o thusa ho fumana sehlahisoa seo o se batlang.

Hlokomela: Bakeng sa liphetho tse ntle, sebelisa modular screw elements. U ka li fetola hore li lumellane le thepa ea hau le ts'ebetso ea hau.

Ho qhibiliha le Homogenization

Ha thepa e ntse e tsoela pele, ea chesa 'me ea qhibiliha. Twin screw extruder e na le libaka tse ngata tse futhumatsang haufi le barrel. Sebaka ka seng se na le taolo ea sona ea mocheso. U ka beha mocheso o nepahetseng bakeng sa mohato ka mong. Ka mohlala, polypropylene e qhibiliha ka 170 °C. Matla a mangata a futhumatsa thepa pele e qhibiliha. Mocheso o nyoloha ka potlako, hangata ka nako e ka tlase ho metsotswana e mmedi.

• Ho nka hoo e ka bang 77.75 kW ho futhumatsa polymer e tiileng ho 170 °C ho 1200 kg/hora.

• Ho qhibilihisa polymer ka sekhahla sena ho sebelisa hoo e ka bang 20.0 kW.

• Kakaretso ea matla a ho qhibiliha ke hoo e ka bang 0.081 kWh ka kilogram.

• Matla a khethehileng a mochini bakeng sa ho qhibiliha ha resin ke 0.092 kWh/kg ho 400 rpm le 0.097 kWh/kg ho 800 rpm.

• Matla a ho futhumatsa se qhibilihisang mocheso a fetoha ka lebelo la sekoti: 40.17 kW ho 400 rpm (221.5 °C), 42.9 kW ho 600 rpm (225 °C), le 47.6 kW ho 800 rpm (231 °C).

Ha polymer e qhibiliha, ho kopanya likarolo le ho tsoa mocheso le ho kopanya. Li-mixer tsa spiral le li-mixx tsa mokhoa oa Maddock li pshatla li-gel le ho jala metsoako. Mohato ona o bohlokoa bakeng sa ho kopanya polymer mme o etsa hore sehlahisoa sa hau se be se lekanang.

Keletso: Sebelisa sekhahla se nepahetseng sa screw le mocheso. Sena se thibela tšenyo ea polymer. Sheba libaka tse chesang 'me u itokise ho boloka lintho li bolokehile.

Mokhoa oa Extrusion

Ka mor'a ho qhibiliha le ho kopanya, thepa e ea lefung. Lefu le bopa thepa hore e be li-pellets, maqephe, kapa mefuta e meng. Boloka sebaka sa lefu le ho tsoa ho sona se hloekile ho thibela li-blockages. Sheba liphetoho tsa khatello 'me u fetole li-skrini ha ho hlokahala.

Mona ke tsena mehato e ka sehloohong ts'ebetsong ea extrusion:

1. Lokisetsa thepa ea hau 'me u hlahlobe mochine.

2. Qala mochine ha mocheso o nepahetse.

3. Butle-butle potlakisa li-screws 'me u shebe torque.

4. Hlahloba le ho lokisa tshebetso ha ho hlokahala.

5. Khaotsa ho fepa, sututsa ntho ya ho qetela, ebe o tima matla.

You can use the twin screw extruder for many plastic jobs. It works well for polymer compounding, masterbatch, le ho recycle. The process gives you good, steady products every time.

Hlokomela: To avoid downtime, always follow a maintenance schedule. This keeps your extruder working well and your process on track.

Benefits of Twin Screw Extruders

Superior Mixing and Venting

Twin screw extruders mix materials much better. They use two screws that fit together. These screws make strong forces that help blend things. O ka kopanya li-filler le li-additives hore tsohle li be bonolo. Mochine o boetse o tlosa likhase tse mpe ha o ntse o kopanya. Sena se boloka sehlahisoa sa hau se le ntle. Tafole e ka tlase e bontša kamoo mafahla screw extruders molemo ho feta li-extruders tsa screw e le 'ngoe:

• Li-extruder tsa twin screw li kopane hantle ka lebaka la moralo oa tsona.

• Li laola mocheso le ho tlosa likhase tse mpe ha li ntse li sebetsa.

• Ba kopanya li-filler le li-additives e le hore ntho e 'ngoe le e' ngoe e lekane.

Bokhoni ba Tlhahiso e Phahameng

Twin screw extruder e ka etsa lihlahisoa tse ngata kapele. U ka sebetsana le lintho tse ngata ka nako e khutšoanyane. Lik'hamphani tse ngata li sebelisa mechine ena ho etsa lintho. Chate e ka tlase e bonts'a hore na liindasteri tse fapaneng li sebelisa li-extruder tse peli tsa screw:

Fetile 70% ea polasetiki ea boenjiniere sebelisa li-fin screw extruders. Baetsi ba li-snack le lik'hamphani tsa lithethefatsi le bona ba sebelisa mechini ena bakeng sa tlhahiso e phahameng.

Ho Itlhoekisa le ho Itlhokomela

Li-fin screw extruders itlhoekise ha ba ntse ba sebetsa. Sena se thibela thepa ho haha ​​ka hare. Ha ho hlokahale hore u emise mochine hangata ho o hloekisa. Sena se boloka chelete mme se boloka tlhahiso ea hau e tsoela pele.

Keletso: Sheba mochini oa hau khafetsa ho emisa mathata. Sena se thusa extruder ea hau hore e lule e le hantle.

Lintho tse Fetohang

Li-fin screw extruders e ka sebetsa ka lisebelisoa tse ngata. U ka li sebelisa ho kopanya, masterbatch, lipolasetiki tsa boenjiniere, terata le lisebelisoa tsa cable, polasetiki e senyehang, thermoplastic elastomers, le ho feta. Ba ka boela ba sebetsa lipolasetiki tse tsosolositsoeng le thepa e matla. Sena se bolela hore o ka etsa lihlahisoa tse fapaneng ntle le ho fetola mechini.

• Ho kopanya

• Masterbatch

• Phetoho ea polasetiki ea boenjiniere
