Extrusion inogona kuve nzira yekugadzira iyo vinyl inozonyungudutswa uye kuumbwa kuita chimiro. Extrusion inoburitsa zvinhu zvakaita semamiriro ekunze-kubvisa, tubing, fenzi, dhizaini njanji, mahwindo emafuremu mapikicha uye machira ejira, uye tambo insulating zvinhu.

Maitiro anotevera anotanga nekudya zvinhu zvepurasitiki (legumes, granules, powders kana sprays) kubva muhopi kuenda kudura reextruder. Jira iri rakasvinwa madhiraini kuburikidza nemagetsi kuburikidza nekuchinjisa masiruu akagadzirwa.
Normal Extrusion Substances

Inosanganisira asi haina kuganhurirwa kuPVC, PP, PC, PE uye ABS (acrylonitrile butadiene styrene)
Models of Die

Kune nguva dzose kune nhamba yakawanda yevanofa. Zvese zvinofa zvinobvumidza panzvimbo yekusaenderera mberi kugadzirisa senge jekiseni kuumba nepo panogona kunge paine mutsauko pakati pekuoma nemhando.
Sheet Extrusion

Sheet extrusion inoshandisa extruding mapepa epurasitiki kana kunyange mafirimu akanyanya kukora kuti asafuridzirwa. Pamusoro pezvo, kune marudzi maviri ekufa: T-chimiro uye jasi hanger. Nhungamiro uye chinangwa chevanofa vanogara vachidzoreredza rukova rwepurasitiki kunyunguduka kubva kune imwe spherical inobuda neextruder yako kune imwe planar kufamba.

Kazhinji co-extrusion inogona kushandiswa kushandisa akati wandei pamusoro pejira rekutanga kuwana zvimwe zvinhu zvakaita sekugadzirwa kweUV-absorption, oxygen permeation resistance, kana kuratidza simba.

Iyo yakajairwa post-extrusion kosi yekuita yevinyl sheet inventory ndeye thermoforming. Muchokwadi, iyo pepa iri pasi pemamiriro ekudziya kusvika nyoro (vinyl), zvakare kuumbwa uchishandisa mildew kune imwe nyowani fomu. Ndiyo vacuum. Kana vacuum ichinge yashandiswa, kutarisisa kwakakosha zvakanyanya uye kunokanganisa zvakanyanya kugadzira nguva dzekutenderera nekuda kwesimbi zhinji.
Kufuridza Extrusion

Kugadzirwa kwevinyl membrane kuti uwane zvinhu zvakaita se sheeting uye mikwende yekutenga. Inoshanda pakushandisa mutsara wakaputika membrane.

Usati wasiya expire kuendesa tubing iri kutonhora kunyungudika. Iyo dhayamita yaro yakawedzera kuburikidza nemhepo dhizaini, uye zvakare tubing yakadhonzwa kumusoro nemapikisi, ichiwedzera purasitiki kubva mukukwezva mirairo uye retina. Iyo dhizaini zvakare inosiyanisa cheni dzepolymer, zvakare kuvhuvhuta kunokurudzira membrane kuti ive skinnier kana ichienzaniswa neiyo grunt tubing. Kana iyo bhaisikopo rikakwezvwa zvakanyanya kupfuura iro rakanyatso kupeperetswa (kuti iyo yekupedzisira tubing dhayamita iri pedyo nepakati dhayamita) mamorekuru ealuminium angangove akanyatso kurongeka pamwe chete uchishandisa ese edhirowa manejimendi, kuvaka firimu rakasimba mukati. nenzira iyi, zvisinei nekushaya simba kubva munzira chaiyo. Iyo membrane iyo dhayamita yakakura kana ichienzaniswa neyepakati dhayamita ichave ine simba kubva kune kwayo manejimendi, zvisinei kwete kubva kune inokwezva manejimendi.

Inokwezvwa kuisonera mu-lay-flat chubhu, inogona kunyungudutswa kana kukandwa kune angangoita mabits maviri eplywood, uku membrane ichitonhora.
Coating Extrusion

Extrusion bhachi parizvino iri kuita dhipoziti kana kukanda firimu nzira. Idzi nzira mbiri dzinovavarira kupfeka imwe jaketi pane rollstock yepepa rakajeka kana firimu. Somuenzaniso, nzira iyi inogona kushandisa coating. Saka kuti iite kuti isamirire kuve nemvura yekusimudzira maficha ebepa. Iyo layer inogona kusetwa kuti ishandiswe kukwezva 2 zvinhu.
Extruder Category

Kune mamwe marudzi maviri chete e screw extruders. Iyo manejimendi imwe neimwe screw spins mukuenzanisa neimwe iri kufona senge iyi nomenclature. Ese ari maviri screws anomonyoroka kana clockwise kana counterclockwise. Zvinoratidzwa kuti, kune yakapihwa mhiri-chikamu nharaunda uye mwero wekupindirana, axial kumhanya uye mwero wekusanganiswa wakakura mukutenderedza mbiri mbiri extruder. Pressure buildup yakakura mune extruders. Iyo twist dhizaini iri mune izvo zvinosanganisa uye zvinotakura zvikamu. Izvi ndezvekuronga kubvumidza kugadziridzwazve modular kuti iwane kutsiviwa kana maitiro ekugadzirisa zvikamu nekuda kwekupfeka kana kukuvara kusingagadzirike.

Maitiro ePlastiki Extrusion

Kubva pakuwedzererwa kwemapurasitiki, iyo undo makemikari zvinhu zvinowanzo kurudzi rwemanurdles, anowanzo kunzi resin, iyo inogona kuregedzerwa kupomba nepamusoro-yakaiswa hopper kune reservoir ye extruder. Jira rinopfuura nenzira yekudyisa (kuvhura padhuze nekuseri kwedhiramu) uye rinouya rakabatana neshinda yese yakamonyoroka. Kusveta uye ngura zvinowedzera kudziya. Mukutungamira chikamu chekoni, iyo cushioned vinyl inofamba kuti ibvise chero kusvibiswa uye zvakare inosiya iyo twist. inopinda kupera mushure mekubva mundiro yekupwanya. Chinhu chinoda kutonhora pasi nekudhonza pane extrudate uye zvakare izvo zvinoziva.
Zvakanakira Plastic Extrusion
yakaderera mutengo

Mukupesana nemamwe ekuumbwa maitiro extrusion molding inogona kunyanya kuvimbika uye inouya nemutengo. Kunyangwe iyo extrusion maitiro anoshandisa thermoplastics uye zvakare ivo vanoona kunyunguduka uye kurira. Mari yekurasa uye zvigadzirwa zvese zvakaderera. Compound extrusion zvishandiso zvinoshanda uye zvakare izvi zvinodzikisira mukana wekushomeka kwemasheya.
Kumhanya Kwepamusoro

Iyo extrusion maitiro inogadzira uye inokurumidza mukugadzira contours muhurefu. Masevhisi uye zvigadzirwa zvinogona kugadzirwa muhuwandu hukuru, uye pane zvishoma kutambisa.
