Multi-layer blowing moldinginovaka madziro emudziyo kubva kune maviri kana anopfuura epurasitiki akaturikidzana, imwe neimwe ichiita basa rakasiyana - chipingamupinyi chinovharira mweya weokisijeni kana hupfu hwehutsi, musimboti wakadzokororwa kuderedza mutengo, matehwe emhandara kuitira nzvimbo yakachena. Iwo akabatanidzwa pamwe chete kuburikidza nemusoro wekufa, saka madziro anobuda asina musono uye akasanganiswa. Unochida kana chinhu chimwe chisingakwanisi kuita zvese: tangi remafuta risingade kubuda mhute, bhodhoro remuto rinofanirwa kuchengetedza okisijeni kwegore, mudziyo unofanirwa kurova zvakadzokororwa-zvirimo pasina kusvibisa zviri mukati. Kinggle's KGH curved-arm machines inomhanya 1 kusvika 6 layer pamidziyo kubva pa5 kusvika ku30 litres.
Mazhinji mabhodhoro epurasitiki chinhu chimwe, chidziro chimwe, chakaitwa. Svina HDPE kuburikidza nekufa, pfutidza kumusoro, bvisa. Yakareruka, yakachipa, uye yakakodzera kune yakawanda yakawanda yemidziyo. Asi zvimwe zvigadzirwa zvinokumbira chimwe chinhu purasitiki imwe chete isingakwanise kupa. Uye ndipo panopinda multi-layer.
Isu tinowana kutsika kwakadzikama kwevatengi vakaudzwa kuti vanoda "co-extrusion" kana "muchina-mutsetse wechitanhatu" uye vasina chokwadi chekuti chii chinovatenga - kana kuti vari kutengeswa. Saka heino vhezheni yakajeka: izvo zvidimbu zvinoita, pazvinokodzera, uye kana iwe uri nani pakugara imwechete-layer.
Chii chinonzi "multi-layer" chinoreva pafekitari pasi
Single-layer is one extruder feeding one die head with one material. Multi-layer akati wandei extruder - imwe neimwe ichinyungudusa resin yakasiyana patembiricha yayo - yese ichidyisa imwe yakagovaniswa.co-extrusion kufa musoro. Mukati memusoro iwoyo, hova dzakanyunguduka dzakapatsanurwa dzinoturikidzwa muzvikamu zvakadzika, saka jeri rinodonha rakatoturika. Inobva yavhuvhuta sezvakaita mamwe maprison.
Funga nezvayo seplywood, kunze kwekunge matanda akaumbwa uye akasanganiswa mupfuti imwe chete kwete kunama semashiti. Uye mazwi maviri auchanzwa - "multi-layer" uye "co-extrusion" - anotsanangura chinhu chimwe chete kubva kumagumo akasiyana. Co-extrusion ndiyo nzira; multi-layer ndiyo mhedzisiro.
Layer kuverenga kazhinji kumhara pa2, 3, 5, kana 6, uye nhamba yega yega ine chikonzero kumashure kwayo. Tichasvika kwazviri. Kutanga, iwo machira pachawo.
Yese layer ndeyei chaizvo
Iyo barriers layer - chikonzero nei akawanda-akawanda-layer mabasa aripo
Plain HDPE nePET zvakanaka pazvinhu zvakawanda, asi zvine porous kumagasi nekufamba kwenguva. Kune zvakawanda zvigadzirwa, ndiani ane hanya. Kune vamwe, ndiwo mutambo webhora. Oxygen inokambaira mukuparadza chikafu. Fuel vapor inokambaira kubva mutangi inotyora mitemo yekuburitsa uye idambudziko rekuchengetedza. Chinhu chinonyungudutsa chine hasha chinoshanda zvishoma nezvishoma nepamadziro chachisingade.
Ndizvo zvinogadziriswa nebarrier layer.EVOH(ethylene vinyl doro) ndiyo chiyero chegoridhe chekuvharira okisijeni nemahydrocarbon;PA(nylon) ndiyo imwe sarudzo yakajairika. Heino kubata kunokwevera vanhu kumusoro: EVOH inodhura, uye inovenga unyoro - kunyorova kunoparadza mashandiro ayo. Saka haumbozviise pamusoro. Iwe unoiviga nepakati, sliver ye millimeter gobvu, yakachengetedzwa kumativi ose. Iyo yakaonda EVOH musimboti inoita inovharira; HDPE yakachipa inoita kuwanda kwemadziro. Diki layer, yakakura mhedzisiro.
Iyo yakadzokororwa / regrind layer - mutengo uye PPWR
Mutsara wega wega wekuumba unoburitsa trim - iyo pinch-off tsvina kumusoro uye muswe wechikamu chimwe nechimwe. Gaya uye une zvinhu zvakanaka, kwete zvinhu zvauri kuda kubata chigadzirwa kana kuratidza kunze. Saka unoidyisa zvakare seyakavigwa yepakati layer. Yemahara kupinza, hapana kukanganisika pane izvo zvine basa.
Iwo manomano mamwe anobata post-mutengi zvakadzokororwa zvemukati. Sandwich PCR resin mukati mepakati, chengeta virgin chikafu-giredhi purasitiki pamatehwe emukati nekunze, uye iwe unogona kurova zvakadzokororwa-zvirimo zvinotarirwa - kusanganisira zvikumbaridzo zveEU zvatakavhara muchidimbu chekutevedzera PPWR - pasina zvinhu zvakadzokororwa zvakambobata zviri mukati mebhodhoro. Kune akawanda mabhureki ari kudzingirira 2030 PCR mandates, akawanda-layer ndiyo nzira yakachena kwazvo iripo.
Sunga zvidimbu - izvo munhu wese anokanganwa
Iye zvino chikamu chinobata vatengi kunze kana vari kudhura basa. EVOH uye naironi hazvibatanidzi kune polyethylene. Zviise padivi nepadivi uye ivo vanozodonhedza - zvidimbu zvinoputika senge laminate yaenda zvisirizvo, uye chikamu chaparara.
Saka pakati pezviviri zvese zvisinganamatire, unoda atie layer: resin yakatetepa inonamira inobata mativi ese. Ichi ndicho chikonzero "nhanhatu-layer" mafuta tangi iri yekunze HDPE, regrind, tie, barriers, tie, yemukati HDPE. Zvisungo zvekusungirira zvitanho zvakare. Vasiye kunze kwechirongwa chako uye iwe ungave uine chikamu chinodonha kana chiyero chekuverenga chisingawanze. Havasi vekusarudza, uye ivo chinhu chaicho chemutsara.
Iko kune akawanda-layer anowana mutengo wayo
Motokari matangi emafuta (iyo matanhatu-layer classic)
This is the textbook case. Tangi yemafuta epurasitiki haigone kurega hydrocarbon vapor ichipinda nemumadziro ayo - mitemo yekuburitsa haibvumire, uye inyaya yekuchengetedza. Iyo yakajairwa kuvaka ndeye HDPE chimiro, regrind layer, tie layer, EVOH barriers, imwe tie layer, uye yemukati HDPE layer. Matanho matanhatu, neEVOH ichiita kuvharika kwekuvhara uye tie layer dzakabata sandwich pamwechete. Kinggle's catalogs inonyora matangi emafuta pasi pezvikamu zvemotokari, uye matangi ndiwo chaiwo mhando yeinorema, inoda chikamu chakakomberedzwa-ruoko multi-layer michina inovakwa kugadzira.
Chikafu, chinwiwa uye cosmetic packaging
Ketchup, sosi, kana bhodhoro remuto rinofanirwa kugara pasherufu kwegore rinoda chinovharira mweya weokisijeni, kana zvirimo oxidise uye zvinoparadza. Rusvingo rune-matatu (mhandara / chipingamupinyi / mhandara) kana yakazara shanu-layer kuvaka inobata izvo. Cosmetics inosvika kune akawanda-layer nekuda kwechikonzero chakasiyana zvakare - ganda rekunze rine ruvara kana pearlescent pamusoro peimwe yemukati layer, kana yakajeka "view stripe" yakadhirowewa pasi padivi pebhodhoro rakajeka kuti mushandisi aone kuti yasara chigadzirwa chakawanda sei. Mutsetse uyu uri mubhodhoro rako rekugezesa? Co-extruded.
Agrochemical uye imba-makemikari midziyo
Mushonga wezvipembenene une hutsinye kana chinonyungudutsa chinogona kupinda kana kushushikana-kutsemura madziro akajeka eHDPE pamusoro pemwedzi yekuchengetedza. Chivharidzo kana fluorinated layer inotenga makemikari kuramba uye hupenyu hwesherufu, ndosaka yakawanda yeagrochemical packaging ine-multi-layer pane imwe chete. Aya mabhodhoro emazuva ese-makemikari uye agrochemical anogara mukati chaimo meKinggle yekurongedzera maapplication - iwo mabhodhoro mamwe chete emhuri michina midiki yemaoko yakakomberedzwa inomhanya zuva rese.
Saka ma layer mangani aunoda chaizvo?
Mamwe maturu anoreva mamwe maextruder, mutengo wakawanda, uye zvimwe zvinosiyana kuti tiite. Nhamba yakakodzera ndiyo vashoma vanoita basa - kwete iyo yakawanda mutengesi anogona kukutengesa iwe. Zvinenge:
| Layer | Kushandiswa kwakajairika | Sei |
|---|---|---|
| 1 | Mvura, ma detergents akawanda, plain jerry cans | Chinhu chimwe chinoita zvese zvinodiwa |
| 2–3 | Gadzirisazve kushandisa, ruvara/kukamukana kwechiso, mwenje unodzivirira | Viga musimboti wakadzokororwa, kana wedzera chinovharisa chine mwero |
| 5 | Chikafu uye chinwiwa chine yakazara oxygen barriers | Chipingamupinyi + sunga mitsara kumativi ose maviri |
| 6 | Matangi emafuta, anoda kupemerwa mabasa | Barrier + zvisungo + regrind + chimiro |
Kana chinhu chimwe chete chikatosangana nehupenyu hwesherufu yechigadzirwa chako, makemikari kuramba, uye zvakadzokororwa-zvirimo zvinodiwa, usabhadhare matinji ausingazoshandise. Multi-layer chishandiso chematambudziko chaiwo, kwete kusimudzira nekuda kwayo.
Chii chinodiwa ne-multi-layer kubva kumushini
Hechino chinhu icho dhizaini dhizaini risingakuudzi: yega yega yega inoda extruder yayo yekudyisa iyo co-extrusion kufa musoro. Tangi-matanho matanhatu anogona kureva maextruder mashanu kana matanhatu akaungana akatenderedza musoro mumwe, imwe neimwe ichinyungudutsa resin yakasiyana patembiricha yaro, imwe neimwe ichinyatsoita metering chaiyo saka dhizaini rayo rinogara rakaita gobvu munzira yese yakatenderedza jeri. Ndiwo muchina wakasiyana zvakanyanya kubva kune imwechete-layer bhodhoro mutsara.
Kinggle'sKGH curved-arm seriesyakavakirwa basa iri - 1 kusvika ku6 akaturikidzana pamidziyo kubva pa5 kusvika ku30 malita. Nhamba dziri shure kwayo ndedzechokwadi: kurovera simba kubva pa200 kusvika 300 kN kumativi ese, HDPE plasticising kusvika 300 kg/hr paKGH30D, uye MOOG-inodzorwa madziro-kukobvu chirongwa. Iko kudzora ukobvu kunotonyanya kukosha pane akawanda-layer pane imwe chete, nekuti iwe wakabata akati wandei akatetepa - kusanganisira chipingamupinyi chinogona kunge chiri chidimbu chemirimita - kufungidzira panguva imwe chete, nzira yese yakatenderedza chikamu. Ita zvisizvo uye chipingamupinyi chako chinotetepa papfudzi, ndiko kwausingade gap.
Izvo zvakakoshawo kuziva zviri mukati meiyo control system, nekuti akawanda-layer anorarama kana kufa pane chaiyo kurongeka pakati pe extruders. Michina yaKinggle inomhanya pane maindasitiri-giredhi zvikamu - Mitsubishi PLC, MOOG servo control, OMRON uye Schneider magetsi - rudzi rwekiti inochengeta mashanu eextruder metering musync shift mushure mekuchinja.
Zvikanganiso zvina zvatinoona vatengi vachiita
- Kutenga maraya ausingadi.Kana yakajeka HDPE ikasangana nehupenyu hwako hwesherufu uye zvakadzokororwa-zvirimo zvibodzwa, muchina-matanho matanhatu imari yakagara isina basa. Matanidza mitsara nedambudziko chairo.
- Kukanganwa tie layers mubhajeti.Iwo chaiwo akaturikidzana uye mutengo chaiwo, uye kuvasiya kunze ndiyo inokurumidza nzira yechikamu chinopisa. Verenga kubva pakutanga.
- Kuisa chipingamupinyi panzvimbo isiri iyo.EVOH pamusoro kana pedyo nechepamusoro, panosvika mwando, inorasa kushanda kwawakabhadhara. Ndeyemukati yakachengetedzwa.
