1. Extrusion: Ka Base Strap dilan

1.1 Extrusion (bɔli) taabolo

Extrusion ye PP strapping dilanni taabolo fɔlɔ ye. Ka kɛɲɛ ni polimɛri baarakɛcogo sariyaw ye, poliporopilini resin min bɛ kɛ granulaire ye, o bɛ don extruder kɔnɔ, o yɔrɔ la a bɛ sumaya fo a ka wuli. O kɔfɛ, polimɛri wulilen bɛ waajibiya ka tɛmɛ cogoya dilancogo dɔ fɛ min b’a kɛ bandi fla ye min bɛ taa ɲɛ.

Paramɛtiri jɔnjɔn minnu bɛ extrusion na olu ye:

• Funteni funteni : A ka kan ka kɔlɔsi yɔrɔ kɛrɛnkɛrɛnnen dɔ kɔnɔ walasa ji ka bɔ tuma bɛɛ

• Die design : A bɛ bandi fɔlɔ bonya ni a janya dantigɛ

• Bɔli hakɛ : A bɛ nɔ bila nɛnɛ ni a kɔfɛ sɔgɔsɔgɔli la

1.2 Nɛnɛ ni sɔgɔli

Ni a bɔra die kɔnɔ, o bandi funteniman bɛ tɛmɛ nɛnɛbɔlan dɔ fɛ—a ka c’a la, jisumayɔrɔw walima wuluwulu nɛnɛmaw. Ka kɛɲɛ ni fɛn dilanni cogoyaw ye, nɛnɛ min bɛ kɔrɔsi, o bɛ a to a ka gɛlɛya cogo kelen na, wa a bɛ kɔnɔna degunw bali minnu bɛ se ka gɛlɛyaw lase u ma sɔgɔsɔgɔli waati.

1.3 Mun na extrusion nafa ka bon jogo laban na

Extrusion (bɔli) taabolo la, polimɛri cakɛdaw bɛ siri ɲɔgɔn na k’a sɔrɔ u ma kɛ cogo si la. O fɛn in fanga ka dɔgɔn ani a janya ka bon—a man ɲi doni tali baara la. Extrusion (bɔli) bɛ jusigilan sigi: fɛn min bɛ wuli ka bɔ a nɔ na, ​​o bɛ kɛ cogo min na, o bɛ kɛ cogo min na, o bɛ kɛ cogo min na, o bɛ kɛ sababu ye ka fɛn dɔ kɛ min bɛ se ka kɛ sababu ye ka fɛn dɔ kɛ min bɛ se ka kɛ fɛn ye min bɛ se ka kɛ fɛn ye min bɛ se ka kɛ fɛn ye min bɛ se ka kɛ fɛn ye min bɛ se ka kɛ fɛn ye min bɛ se ka kɛ.

2. Ka i senw kɔrɔta: O ye fɛɛrɛ kɔrɔba ye

2.1 Ja nɛnɛ ye mun ye?

Kɔrɔbɔli — min bɛ wele tuma caman na ko ja nɛnɛma — o ye wale ye min bɛ PP sirili fanga di a ma. Ka kɛɲɛ ni patenti sɛbɛnw ye minnu bɛ kuma sirilanw dilanni kan, bandi min bɔra kɛnɛma, o bɛ tɛmɛ wuluwuluw fɛ minnu b’a kɔrɔta ni tension ni funteni kɔrɔsilen ye. O sɔgɔli bɛ polimɛri cakɛdaw sama minnu sirilen don k’a sɔrɔ u ma kɛ cogo si la walasa u ka bɛn ɲɔgɔn ma sirilan janya la.

2.2 Jatebɔ Ratio (Jaa Ratio).

Draw ratio ye paramɛtɛrɛ jɔnjɔn ye stretching (sɔrɔli) la. O ye sirilan janya laban ni a janya fɔlɔ hakɛ ye a bɔli kɔfɛ. Ka kɛɲɛ ni izini ka fɛn ɲɛfɔlenw ye, PP sirili hakɛ minnu bɛ kɛ, olu bɛ bɔ 4:1 na ka se 9:1 ma.

Jatebɔ hakɛ minnu ka ca, olu bɛ dɔ fara sɔgɔli fanga kan nka u bɛ dɔ bɔ janya la. Dilanbagaw bɛ jatebɔ hakɛw sugandi ka da a kɛcogo laɲininen kan.

2.3 Funteni hakɛ kɔlɔsili sɔgɔsɔgɔninjɛ waati

Funteni min bɛ kɛ sɔgɔli waati la, o de b’a jira polimɛri cakɛdaw bɛ bɛn ɲɔgɔn ma cogo min na. Ka kɛɲɛ ni polimɛri baarakɛcogo kunnafoniw ye, ka i senw kɔrɔta funteni hakɛ ɲuman kɔnɔ, o bɛ ɲɛsincogo kelen ma ani masinko cogoya basigilenw. Ni funteni dɔgɔyara kojugu, a sirilan bɛ se ka kari walima ka fin; ni a ka bon kojugu, cakɛdaw bɛ se ka lafiya sani u ɲɛsincogo ka ban.

Jushuo Packaging la, an ka fɛn dilanni siraw bɛ funteni hakɛ jateminɛ tigitigi mara sɔgɔli waati bɛɛ la, ka a to molekiyɔmuw bɛ bɛn ɲɔgɔn ma cogo basigilen na kulu kelen-kelen bɛɛ kɔnɔ.

3. Molecules (Molecules Alignment): Kɔrɔbɔli (Locking In the Structure) la

3.1 Molecules alignment ye mun ye?

Molecules alignment (molecules alignment) ye sɔgɔsɔgɔninjɛ ɲɛtaa nɔ ye. Ni polimɛri cakɛdaw bɛ ɲɔgɔn sɔrɔ sirilan janya la, u bɛ jɛɲɔgɔnya barikamaw dilan molekiyɔmuw ni ɲɔgɔn cɛ ani ka u yɛrɛ tanga bɔgɔbɔgɔli ma. O jɔcogo min bɛ ɲɔgɔn kan, o de bɛ PP strapping di a ka tensile strength ma.

Ka kɛɲɛ ni fɛnw dɔnniya kunnafoniw ye, orienté poliporopilini bɛ se ka barika sɔrɔ siɲɛ caman ka tɛmɛ fɛn ma min ɲɛsinnen tɛ, n’a janya ye kelen ye. Labɛncogo fana bɛ dɔ bɔ janya la—a sirilan tɛ wuli dɔɔni doni kɔrɔ, ka tension mara ni pakew bɛ sigi.

3.2 Funteni sigicogo : Ka sigida labɛncogo sabati

A sɔgɔlen kɔfɛ, sirilan bɛ funteni sigili kɛ. Ka kɛɲɛ ni patenti sɛbɛnw ye, funteni sigili bɛ kɔnɔna degunw lafiya ani ka fɛnɲɛnamafagalanw jɔcogo ɲɛnama sabati, o b’a to sirilan bɛ a ka jogo mara waati kɔnɔ ani funteni cogoya caman na.

3.3 Orientation biaxial ni longitudinal (yɔrɔjan siratigɛ la).

PP strapping bɛ se ka ɲɛsin sira kelen ma (longitudinal) walima fan fila fɛ (biaxial). Ka kɛɲɛ ni patenti kunnafoniw ye, biaxial orientation — min bɛ molekiyɔrɔw labɛn janya ni bonya sira fila bɛɛ la — o bɛ se ka kɛ sababu ye ka ɲɔgɔndan janyalenw kɛlɛli ɲɛ. PP strapping min ka ɲi kosɛbɛ, o fanba bɛ janya janya ni orientation transversale kɔrɔsilen fara ɲɔgɔn kan.

4. Mun na fɛn dilanni kɔlɔsili nafa ka bon

4.1 Bɛnkansɛbɛnw ni ɲɔgɔn cɛ

Molecules (molecules) ɲɔgɔndan basigilen bɛ a ɲini ka extrusion (bɔli) funteni, nɛnɛ hakɛ, draw ratio (janya hakɛ) ani heat-setting cogoyaw kɔlɔsi tigitigi. Ka kɛɲɛ ni jogoɲumanya sariyaw ye, feerekɛlaw minnu bɛ ni taabolo kɔlɔsili ye ka ɲɛ, olu bɛ sirilanw dilan ni kari fanga ni janya basigilen ye batɛmuw kɔnɔ.

4.2 Fɛn dilanni min tɛ bɛn ɲɔgɔn ma, o bɛ jira cogo min na

Ni fɛn dilanni paramɛtɛrɛw bɛ ɲɔgɔn ta, o jaabiw bɛ bɔ foro kɔnɔ:

4.3 Ka fɛnw dilanbagaw ka sekow jateminɛ

Ka kɛɲɛ ni sanni kɛcogo ɲumanw ye, sannikɛlaw ka kan ka feerekɛlaw jateminɛ ka da ninnu kan:

• Taabolo kɔlɔsili fɛɛrɛ

• Batch consistency sɛbɛnw

• Jogoɲumanya seereyaw

• Sɛnɛfɛnw dilanni seko ni dannaya

Jushuo Packaging la, an ka fɛn dilanni taabolo bɛ extrusion, stretching, ani heat-setting fɛɛrɛ kɔrɔlenw don a la walasa ka molekiyɔmuw ka ɲɔgɔn bɛn cogo basigilen na ani ka sirili baara kɛ min bɛ se ka da a kan.

Farankan

PP strapping dilanni bɛ taabolo jɔnjɔn saba de la: extrusion , stretching , ani molecular alignment . Extrusion bɛ basigi sirilan dilan ka bɔ poliporopilini resin wulilen na. Ka sɔgɔsɔgɔ—ja nɛnɛ na—o bɛ polimɛri cakɛdaw sama ka kɛ ɲɔgɔn fɛ, ka dɔ fara u sɔgɔli fanga kan ani ka dɔ bɔ u janya la. Molecules alignment, sabatilen ni funteni sigili ye, o bɛ da jɔli la min bɛ PP strapping di a ka doni tali seko ma.
