EVA (Ethylene vinyl acetate copolymer) sɛbɛn ye plastiki ye min ka ca kosɛbɛ, a bɛ kɛ ka caya yɔrɔ caman na i n’a fɔ sanbara fɛnw, bagajiw, farikoloɲɛnajɛ minɛnw, tulonkɛfɛnw, ɛntɛrinɛti kan fɛn dilannenw ka pakew, dugumalanw, filimuw minnu bɛ kɛ ni nɛgɛ ye, a ɲɔgɔnnaw, a ɲɔgɔnnaw, a nɔgɔyacogo ɲuman, a jiginni, a kɛcogo ɲuman, ani a kɛcogo ɲuman.

EVA sɛbɛnw dilanni fɛɛrɛba ye extrusion molding ye, wa minɛn minnu bɛ bɛn o ma, olu ye EVA sɛbɛn bɔli sira ye. Nin fɛn dilanni sira in bɛ tali kɛ PP/PE sɛbɛn layini na min kofɔra ka tɛmɛ, nka ka da EVA fɛnw cogoya kan (kɛrɛnkɛrɛnnenya la, nɔgɔya, sɔgɔli ɲuman, ani fomu bɛ se ka kɛ), minɛnw fana bɛ ni a cogoya kɛrɛnkɛrɛnnenw ye.

Eva Sheet Machine layini dafalen bɛ kɛ kɛrɛnkɛrɛnnenya la nin yɔrɔ ninnu na:

1. Fɛn minnu bɛ kɛ ka fɛnw labɛn, olu ka baarakɛcogo .

·Baarakɛcogo: EVA fɛnɲɛnamafagalanw fanba bɛ kɛ granular cogo la. Ni EVA sɛbɛnw bɛ sɔrɔ minnu bɛ fomu kɛ, a ka kan ka fomu (ac foaming agents) ni farankan wɛrɛw fara a kan (a bɛ kɛ ka fɛn wɛrɛw fara a kan (aw bɛ fɛnw tigɛtigɛ, ka tulumafɛnw kɛ, a ɲɔgɔnnaw).

·Baarakɛminɛn:

·Atomatiki balolan: Aw bɛ EVA fɛnɲɛnamafagalanw ta ka bɔ silo la ka taa extruder hopper la.

·Sumuni kɛcogo: Nin ye minɛnba ye min bɛ kɛ ka fomu sɛbɛnw dilan. A ka c’a la, girinya dɔgɔyali sumanikɛlan bɛ kɛ ka EVA fɛnɲɛnamaw, fomuw ka masterbatch, kulɛriw, a ɲɔgɔnnaw ɲagami ɲɔgɔn na ka ɲɛ ani ka to ka u ɲagami ɲɔgɔn na ani ka u balo extruder kɔnɔ walasa ka formula hakɛ sabatili dafalen sɔrɔ, o ye ko wajibiyalen ye walasa ka fomu hakɛ kelen sɔrɔ.

2. Extruder .

·Baarakɛcogo: Aw bɛ EVA fɛnɲɛnamafagalanw ɲagami, ka u kɛ plastiki ye, ka u ɲagami ɲɔgɔn na. Fomu sɛbɛnw ta la, a ka kan fana ka fomu kɛ ka u jɛnsɛn cogo kelen na nɔgɔ la.

·Ka sɛbɛen masin na:

·Single Screw Extruder: A bɛnnen don ka EVA sɛbɛn gansanw dilan minnu tɛ fomu ye walima minnu tɛ fomu ye, ni u jɔcogo nɔgɔn don ani u musaka ka dɔgɔ.

·parallel ani CO filanin fila-Screw extruder: sugandili min ka ca ani min bɛ baara kɛ ka ɲɛ. A ɲagamini nɔ ka ɲi kosɛbɛ, min bɛ se ka fomu ni ɲɛgɛnw jɛnsɛn ka ɲɛ, ka funteni hakɛ kelen sɔrɔ, ani ka sɛbɛnfura ɲuman sabati. Kɛrɛnkɛrɛnnenya la, a bɛnnen don ka fa ani ka EVA fɛnw falen.

3. Réseau Changeur .

·Baarakɛcogo: Filɛri nɔgɔw ni fɛnɲɛnamafagalanw minnu ma wuli, olu bɛ kɛ ka fɛnw datugu, ani ka fɛnw saniyacogo ni u sanfɛla cogoya sabati. A ka c’a la, o ye hydraulique automatique screen changeur ye min bɛ se ka filɛri screen (filɛlikɛlan) sɛgɛsɛgɛ k’a sɔrɔ a ma masin jɔ, ka a jira ko a dilanni bɛ taa ɲɛ.

4. Mold .

·Type: kɛrɛnkɛrɛnnenya la ni hanger type flat die head ye, a ka flow kanal design bɛ se ka a lajɛ ko fɛn sɔgɔlen bɛ tila ka kɛ cogo kelen na a bonya bɛɛ la, o bɛ kɛ ka sɛbɛnw sɔrɔ ni a janya bɛ to ka kɛ.

·Features: A ka c’a la, mɔli dawolo bɛ na ni fin-Tuning minɛn ye min bɛ se ka danfara ladilan ka ɲɛ yɔrɔ wɛrɛw la walasa ka sɛbɛn ka janya muɲuni kunbɛn.

5. Kalansen saba .

·Function: Nin ye core shaping equipment ye EVA sheet dilanni na.

·cooling and shaping: High-Temperature Molten Billet min bɛ bɔ bɔgɔ la, o bɛ don o yɔrɔnin bɛɛ la, ka don jiribolo saba cɛ, ka nɛnɛ teliya la, nɛnɛji fɛ, ka sɔrɔ ka a sabati ani ka a cogoya.

·Determine thickness and surface effect: A laban janya ni a sanfɛla glossiness (gloss or matte) bɛ dɔn ni danfara ye min bɛ jiribolo saba ni ɲɔgɔn cɛ ani jirisunw sanfɛla nɔgɔya.

·Features: O jirisun saba bɛ se ka teliya ni funteni ladilan u yɛrɛma walasa ka baarakɛcogo wajibiyalenw dafa.

6. Traction Unit .

·Function: Aw bɛ sɛbɛn nɛnɛma ni a cogoya ɲɛminɛ ka ɲɛ ka taa winding minɛn fan fɛ.

·composition : A ka c’a la, a bɛ kɛ ni lastikuw walima silikoni wulilan fila walima u caman ye, ka janya kelen di ani ka sɛgɛnlafiɲɛbɔ bali.

7. Intɛrinɛti kan kɔlɔsili minɛnw (a bɛ se ka kɛ nka a nafa ka bon) .

·beta ray walima infrarouge thickness gauge: waati yɛrɛ la scanning ani display of the transverse thickness curve of the sheet in the traction section, ani ka se ka kunnafoniw di kunnafoniw ma ka ɲɛsin moule ka dacogo otomatiki ma walasa ka se ka a yɛrɛma bonya kunbɛn (ATC), ka jogoɲini kɛcogo ɲɛ kosɛbɛ.

8. Winder .

·Baara: Aw bɛ sɛbɛn in wuli ka a kɛ rollo cogo la. K’a sababu kɛ Eva sɛbɛnw nɔgɔyali ye, ka winding tension (janya) kunbɛn, o nafa ka bon kosɛbɛ.

·Ka sɛbɛen masin na:

·Central winding machine: winding ni core boli ka wuli, min bɛnnen don fɛn suguya caman ma.

·Surface winding machine: A bɛ bobine kɔkanna bila ka wuli ka tɛmɛ friction fɛ, o min bɛnnen don kosɛbɛ fɛnw ma minnu ka nɔgɔn ani minnu bɛ sɔgɔ nɔgɔya la ani u bɛ se ka bobine cogoya ɲuman mara ka ɲɛ. O ye winding fɛɛrɛ ye min bɛ kɛ ka caya EVA sɛbɛnw kama.

·High-End Equipment bɛ ni dual station rotary rewinder ye, min bɛ se ka bobinew caman wuli k’a sɔrɔ a ma masin jɔ, ka se ka a yɛrɛ ka baarakɛcogo sɔrɔ min bɛ to sen na otomatiki la.

9. Kuranko ɲɛnabɔli sira .

·Baarakɛcogo: ‘Sɔgɔsɔgɔninjɛ’ min bɛ sɔrɔ fɛn dilanni sira kan. PLC kunnafoni ni a ka maga-maga-minɛn min bɛ tali kɛ ɲɔgɔn na, o tali, taabolo-taamasenɲɛw bɛɛ i n’a fɔ funteni, juru teliya, wuli-ka-bɔ, janya ani wuli-ka-bɔ-yɔrɔ kelen-kelen bɛɛ bɛ se ka sigi ka ɲɛ ani ka kɔrɔsi.

Fɛnɲɛnamafɛnw ka kan ka kɛ ni girinya hakɛ dɔgɔyali hakɛ ye min bɛ se ka kɛ ka ɲɛsin fomuw farali ma. Balo-masin min bɛ kɛ tuma bɛɛ, o bɛ se ka o ko wajibiyalenw dafa.

Extruder bɛ ni wajibiw ye minnu ka bon kosɛbɛ ka ɲɛsin fɛnɲɛnamafagalan ɲagamini ni a jɛnsɛnni seko ma, ani fila-{0}}Screw extruders de ka fisa. Vis kelen walima filanin fila bɛ se ka kɛ.

Taabolo kɔlɔsili bɛ tiɲɛni caman de wajibiya. Funteni hakɛ kɔlɔsili bɛ nɔ bila fomu hakɛ ni selilɛri jɔcogo la. A ka nɔgɔn kosɛbɛ.

Nɔgɔ jɔcogo bɛ tali kɛ ɲɔgɔn na, nka a dilanni ka kan ka jateminɛ kɛ fɛn min bɛ kɛ ka a wuli, o ka jimafɛnw bɛ sɔrɔ. Standard hanger style moule kunkolo.

Minɛn minnu bɛ tugu o kɔ, n’olu ye roll cander saba ye, olu nafa ka bon kosɛbɛ walasa ka fomu sɛbɛn janya n’a sanfɛla kɔlɔsi. Kalansen saba fana de ka kan ka kɛ.

1. Fɛn dilannenw jɔyɔrɔ: Aw bɛ a ɲɛfɔ ni a dilanni kunba ye fomu ye walima ni a tɛ fomu ye? Fomu hakɛ ye mun ye? O bɛ fɛnw bɔli ni balocogo sugandiliw ɲɛfɔ k’a ɲɛsin u ma.

2. Fɛnw ɲɛfɔcogo : fɛn dilanni bonya hakɛ (i n’a fɔ 1000mm, 1300mm, 1500mm, wdfl) ani a bonya hakɛ (a ka c’a la 0,5mm-10mm).

3. Automation level: Yala aw mago bɛ automatique metering feeding la, automatique écran changer, automatique thickness measure feedback (ATC), ani automatique winding? Olu bɛ se ka fɛn dilannenw cogoya ni u sabatili ɲɛ kosɛbɛ, nka u bɛ dɔ fara musakaw kan fana.

4. Sɛnɛfɛnw dilanni wajibiyalenw: Aw bɛ extruder model (screw diamètre) hakɛ dɔn.

5. Fɛnfeerelaw ka sugandili: EVA baarakɛcogo bɛ taabolo dɔnniyaba de wajibiya. Minɛnw feerela minnu ka baarakɛcogo kɔrɔ ye, minnu bɛ se ka formula bilasirali di, ka u sigi ani ka baara kɛ, ani baarakɛcogo kalan ka kan ka sugandi.

Kuma surun : Eva Sheet Equipment ye fɛnɲɛnamafagalanw bɔli sira ye min kɔgɔlen don fɛɛrɛko siratigɛ la, nka a cogoya bɛ se ka ɲɔgɔn ta kosɛbɛ ka kɛɲɛ ni fɛnw dilanni ye minnu tɛ fomu walima minnu tɛ fomu ye. Koori bɛ sɔrɔ fɛnɲɛnamafagalanw hakɛ tigitigiw tacogo la, nɔgɔya la, a mɔcogo ɲuman na, a mɔcogo tigitigi, ani a wulicogo sabatilen. Sani aw ka wari bila, a nafa ka bon aw ka aw ka fɛn dilannenw wajibiyalenw fɔ ka ɲɛ ni minɛnw feerela ye.
