Extrusion ke ts'ebetso ea tlhahiso e kenyelletsang ho fetisa thepa ka har'a dae ho theha ntho e nang le profil e tsitsitseng ea likarolo. Theknoloji ena e sebelisoa liindastering tse 'maloa tse kenyeletsang polasetiki, tšepe, lijo le meriana. Mechini e sebelisoang ts'ebetsong ea extrusion e etselitsoe ka ho khetheha ho fihlela litlhoko tse ikhethang tsa thepa e ntseng e fetisoa ho netefatsa ts'ebetso le ho nepahala. Sehloohong sena, re tla sheba mefuta e fapaneng ea mechini e sebelisoang ts'ebetsong ea extrusion, likarolo tsa eona, le hore na e sebetsa joang.
1. Single Screw Extruder
The single screw extruder ke mofuta o atileng haholo oa extruder. E na le sekoti sa helical se potolohang ka har'a barrel ea cylindrical. Thepa e tšeloa ka har'a hopper moo e futhumatsoang le ho qhibiliha ha e ntse e tsamaea haufi le screw. Moralo oa screw o lumella thepa hore e kopane, e qhibilihe ebe e pompeloa hloohong ea lefu. Li-extruder tsa screw tse le 'ngoe li sebetsa ka mokhoa o fapaneng haholo 'me li ka sebelisoa bakeng sa lisebelisoa tse fapaneng, ho kenyeletsoa thermoplastics le thermosets tse ling.
2. Twin Screw Extruder
Li-extruder tsa Twin-screw li na le li-screw tse peli tse pota-potileng ka lehlakoreng le le leng kapa le fapaneng. Moqapi ona o lumella ho kopanya hantle le ho kopanya 'me o loketse bakeng sa likopo tse hlokang tekanyo e phahameng ea homogeneity. Li-extruder tsa Twin-screw li sebelisoa hangata tlhahiso ea lijo, meriana le lisebelisoa tse tsoetseng pele tsa polymer. Li-extruder tse nang le li-twin-screw li ka boela tsa sebetsana le mefuta e mengata e fapaneng ea lisebelisoa, ho kenyelletsa le lisebelisoa tse thibelang mocheso.
3. Plunger Extruder
Li-extruder tsa plunger, tse tsejoang hape ka hore ke li-piston extruder, li sebelisa plunger e khutlisang ho sutumelletsa lintho ka har'a phala. Mofuta ona oa extruder hangata o sebelisoa bakeng sa lisebelisoa tseo ho leng thata ho li sebetsa ka li-scruder tse kang li-ceramics le litšepe tse itseng. Li-plunger extruder li ka fihlela likhatello tse phahameng haholo 'me ka hona li loketse lits'ebetso tse hlokang hore ho be le letsoalo le phahameng le li-extrudates tsa matla.
4. Li-extruders tsa maqephe
Li-extruder tsa maqephe ke mechini e khethehileng bakeng sa tlhahiso ea maqephe a bataletseng. Hangata ba sebelisa motsoako oa screw extruder e le 'ngoe kapa mafahla le die ho hlahisa thepa ho lakane. Letlapa le fetisitsoeng le ka pholile 'me la khaoloa ka boholo bo loketseng mefuta e fapaneng ea lisebelisoa, ho kenyelletsa le ho paka, ho haha le likarolo tsa likoloi.
5.e phatloha filimi extruder
Blown film extruder ke mokhoa o ikhethileng o sebelisetsoang ho etsa lifilimi tsa polasetiki. Ts'ebetsong ena, polasetiki e qhibilihisitsoeng e ntšoa ka selika-likoe ebe e atolosoa ho etsa lipululana. Li-bubble li pholile ebe lia honyela ho etsa filimi e bataletseng. Li-extruder tsa filimi tse phatlohileng li sebelisoa haholo indastering ea ho paka ho hlahisa mekotla, pampiri ea ho phuthela le lisebelisoa tse ling tse bonolo tsa ho paka.

Extruder e na le likarolo tse 'maloa tsa bohlokoa tse sebetsang hammoho ho netefatsa ts'ebetso e atlehileng ea thepa:
Hopper: Hopper ke moo thepa e tala e kenngoang mochining. E etselitsoe ho fepa thepa e tala ka ho tsoelang pele ka har'a extruder.
Screw: The screw ke pelo ea extruder. E na le boikarabelo ba ho tsamaisa, ho qhibiliha le ho kopanya thepa e tala ha e feta ka har'a moqomo.
Barrel: Moqomo ke khetla ea cylindrical e nang le screw. Moqomo o na le lintho tse futhumatsang bakeng sa ho qhibiliha 'me e ka ba le libaka tse pholileng bakeng sa taolo ea mocheso.
E-shoa: Lefu ke karolo e bōpang thepa e fetisitsoeng hore e be sebopeho se lakatsehang. Li-Dies li ka etsoa ka mokhoa o ikhethileng ho etsa libopeho tse fapaneng tsa lintho tse kang phala, lakane kapa filimi.
Sistimi ea ho Pholisa: Ka mor'a hore thepa e tlohe lefing, hangata e hloka ho pholile ho boloka sebopeho sa eona. Lisebelisoa tsa ho futhumatsa li ka kenyelletsa libaka tsa ho hlapa metsi, ho pholisa moea, kapa li-roll, ho itšetlehile ka kopo.
Cutting Systems: Lits'ebetsong tse ling, lisebelisoa tse extruded li ka hloka ho khaoloa ka bolelele bo itseng. Litsamaiso tsa ho itšeha li ka kenyelletsoa moleng oa extrusion ho iketsetsa ts'ebetso ena.
Ts'ebetso ea extrusion e qala ka ho kenya thepa e tala ka har'a hopper. Joale thepa e tala e tšeloa ka moqomong moo e futhumatsoang le ho qhibiliha ha e ntse e tsamaea haufi le screw. The screw e etselitsoe ho kopanya hantle thepa e tala le ho e pompa ka har'a lefi. Hang ha thepa e fihla lefung, e qobelloa ka lesoba ho etsa sebopeho se lakatsehang.
Ka mor'a hore extrudate e tlohe lefung, e ea pholile ebe e tiisa. Ho itšetlehile ka mofuta oa extruder le thepa e sebelisoang, mehato e meng e ka 'na ea hloka ho etsoa, e kang ho itšeha, ho pota-pota kapa ho tsoela pele ho sebetsa.
Extrusion ke ts'ebetso ea bohlokoa ea tlhahiso e itšetlehileng ka lisebelisoa tse khethehileng ho hlahisa lihlahisoa tse fapaneng. Ho tloha ho li-extruder tse nang le sekoahelo se le seng le li-twin-screw extruder ho ea ho li-plunger extruder le mochini oa lifilimi o fefotsoeng, mofuta o mong le o mong oa extruder o na le morero o ikhethang indastering. Ho utloisisa likarolo le mesebetsi ea mechini ena ho bohlokoa ho ntlafatsa ts'ebetso ea extrusion le ho fumana liphetho tsa boleng bo holimo. Ha thekenoloji e ntse e tsoela pele, indasteri ea extrusion e kanna ea bona lits'ebetso tse ling tse tla eketsa ts'ebetso le ho holisa menyetla ea ts'ebetso ea thepa.
