Diidmada tooska ah waa mid ka mid ah damacyada soo koraya eefarsamada extrusion.Iyada oo ku saleysan falanqaynta sifada co-wareegaynta furka furayaasha mataanaha ee habka isku dhafka, qodobbada muhiimka ah qaarkood ee ku saabsan qalabka, farsamada, iyo caaryada ee extrusion toos ah oo leh co-wareegaya furaha furayaasha mataanaha ayaa jooga.
Twin-screw extruder waa farsamayn joogto ah oo polymer ah oo si weyn loo isticmaalo.Haddii si toos ah loo soo saari karo, yacni, haddii hal mar la dhammayn karo, waxa loo qaybin karaa laba qaybood oo kala ah: rotation co-directional and hetero-directional rotation.Mataanaha Coaxial waxay isku rogaan isku-dhafka iyo wax-soo-saarka extrusion.Lahaanshaha awood xoog leh oo isku dhafka ah, waxaa inta badan loo isticmaalaa wax ka beddelka, buuxinta, 1 si toos ah kor loogu qaado iyo xaaladaha extrusion caag ah oo lagu qasi karo wax soo saarka synthetic ee Alloys caag ah oo isku qasan hawlgalka, nidaamka extrusion inta badan qaadanaysaa xaaladda extrusion tooska ah modular waa in alaabta waa dhismaha. ee qaab dhismeedka si buuxda u qaso, by kala duwan synfuels fiasco qayb tube, isku darka ee element fur si ay u qanciso extruder dhisi karaa cadaadis ku filan iyo socodka xasiloonida.Marka loo eego habka gaarka ah ee isku dhafka ah ee gudbinta, dhalaalidda, isku darka, hoos u dhigista, isku-dhafka iyo wixii la mid ah, xaaladda co-directional twin-screw extruder ee loo isticmaalo isku-darka ayaa marka hore la falanqeeyaa.
1.Mataan-jiho-jiho ah-maleelin-karoole waxay dejin kartaa cadaadis sare iyo socodka joogtada ah
Xawaaraha wareega iyo saamaynta kala firdhiso, inta badan loo isticmaalo alaabta u baahan qaabaynta cabbirka saxda ah qaybta saxda ah iyo extrusion, sida koorta-jihada mataanaha-dhalaalaya xawaaraha qaraabo sare waxay soo saari kartaa qaab sare extruder mataano-daaqadaha for PVC profile qaabaynta iyo extrusion.Marka la barbar dhigo heerka xiirta iyo diiqada weyn ee xiirid, xawaaraha sare ee wareegga, ayaa natiijada ka sii wanaagsan.Dareemayaasha hal-xidhka ah ayaa la qabsan kara dusha ballaaran, laakiin sifooyinkeeda kala duwan uma fiicna sida saamaynta isku-dhafka ah ee kala firidhsan.Isla mar ahaantaana, xawaaraha sare ee wareega ayaa wiiqay barakaca togan ee furka mataanaha ah si caan ah, hal mar waxaa inta badan loo isticmaalaa in lagu dhejiyo extrusion, marooji doorka guud, si xasiloonida extrusionka.
Naqshad gaar ah iyadoo loo eegayo habka extrusion gaar ah iyo alaabta.
2.Principle of design element fur
Isticmaalka alaabta wax soo saarka gaarka ah waxay u baahan yihiin in ay isku daraan granulation iyo isku-darka isku-darka isku-dhafka ah ee isku-dhafka ah ee isku-dhafka ah ee walxaha mataanaha ah inta badan si waafaqsan " nadiif ah" labada tallaabo ee asalka ah, iyo inta badan oo leh jihada isku midka ah ee iskudhafka mataanaha. iyo hal fur si loo dhammeeyo naqshadeynta, mabda'aani wuxuu go'aamiyaa marinka dhererka waa inuu ahaadaa mid furan, si ay labaduba u galaan.Ka dib markii granulation ee isku dhafka labajibbaaran, maaddada waxaa lagu qaboojiyaa heerkulka qolka, iyo isweydaarsiga alaabtu waxay dhacdaa inta u dhaxaysa baararka halbeegga ah, sida ku cad jaantuska 1 (a) Marka kanaalka qulqulka dheer uu furan yahay, heerkulku mar kale ayuu kor u kacaa ilaa walxaha dhalaalayo.Ka dib laba processing, waxaa suurtagal ah in la furo channel socodka transverse si ay u ogaadaan kororka isticmaalka boosaska boolal ku xiga ee furaha isku mid ah, kororka kharashka processing, kordhinta wareegga wax soo saarka iyo beddelka alaabta.Natiijo ahaan, taariikhda kulaylka ee isku-dhafka ah ee la qaybiyay ayaa kor u kaca, waxqabadkuna hoos u dhaco.si dabiici ah waxay keentaa dhibaato: kartida, laakiin sidoo kale waxay daciifisaa saameynta bara-kaca ee togan.
