PE Blown Film Production Overview Technical and Effective factors

Kakaretso ea Ts'ebetso ea Blown Film Extrusion

Ts'ebetso ea extrusion ea filimi e phatlohang e qala ka ho fepa li-pellets tsa PE resin ka har'a extruder, moo li qhibilihang ebe li homogenized ka motsoako oa mocheso le matla a ho kuta. Joale polymer e entsoeng ka ho qhibilihisoa e qobelloa ka sekhahla se chitja, se etsa tube e tsoelang pele. Moea o kenngoa bohareng ba phapu ena, o e butsoe hore e be bubble. Bubble ena e huleloa holimo, ka nako e le 'ngoe e otlolla filimi ka lehlakoreng la mochini (MD) le transverse direction (TD), mokhoa o tsejoang e le biaxial orientation. Ha bubble e nyoloha, e pholile ka selikalikoe sa moea, e leng se etsang hore polymer e be kristale le ho tiisa. Qetellong, bubble e pholisitsoeng e putlama ka sete ea li-nip rollers ebe e lemalla moqolong. Mekhahlelo ea bohlokoa e susumetsang ts'ebetso e kenyelletsa mocheso oa ho qhibiliha, lekhalo la lefu, sekhahla sa ho phatloha (BUR), bophahamo ba mohala oa serame (FLH), le sekhahla sa ho pholisa.

Lintlha tsa Bohlokoa tse Amang Katleho ea Tlhahiso

Lintlha tse 'maloa li ama ka kotloloho ts'ebetso ea tlhahiso ea lifilimi ea PE:

• Ketso: Sekhahla seo filimi e hlahisoang ka sona. Phallo e phahameng ka kakaretso e bolela bokhoni bo phahameng.

• Boleng ba Filimi: Sena se akaretsa litšobotsi tse kang ho lekana ha botenya, matla a mochine (matla a ho tsieleha, ho thibela ho lla, ho otla ha dart), lisebelisoa tsa optical (haze, gloss), le litšobotsi tse holim'a metsi (coefficient of friction). Boleng bo bobe ba filimi bo lebisa ho eketseha ha litheko le ho fokotsa ts'ebetso.

• Nako ea ho phomola: Ho emisoa ho sa reroang ka lebaka la mathata a kang ho khefutsoa ha filimi, ho bokellana ha thepa, kapa ho se sebetse hantle ha thepa. Ho fokotsa nako ho bohlokoa bakeng sa katleho.

• Tšebeliso ea Matla: Matla a hlokahalang ho qhibilihisa polymer, ho sebelisa extruder, le lisebelisoa tsa ho pholisa motlakase. Ho fokotsa tšebeliso ea matla ho ntlafatsa katleho ka kakaretso le ho fokotsa litšenyehelo tsa ts'ebetso.

• Tšebeliso ea Raw Material: Tšebeliso e nepahetseng ea PE resin le li-additives, ho fokotsa litšila.

Mathata a Tloaelehileng a Tlhahiso ea Lifilimi tsa PE Blown

Leha ho na le tsoelo-pele ea theknoloji, tlhahiso ea lifilimi ea PE e tobane le mathata a 'maloa a tloaelehileng a ka sitisang katleho:

• Thibelo ea Filimi: Ho khomarela ho sa rateheng pakeng tsa lihlopha tsa filimi, ebang ke moqolong kapa nakong ea mehato e latelang ea ho sebetsa. Sena se ka lebisa mathateng a ho phutholoha, ho eketseha ha likhahla, le ho lieha ho hlahisa.

• High Coefficient of Friction (COF): Khohlano e phahameng holim'a filimi e ka baka mathata nakong ea ho tsubella, ho phutholoha le ho fetola ts'ebetso, e lebisang ho khomarela, ho taboha le ho fokotsa lebelo la ho sebetsa.

• Die Build-up: Ho bokelloa ha polymer e senyehileng kapa li-additives ho pota-potiloe ke lefu, ho lebisang ho streaks, li-gel le bofokoli ba lifilimi.

• Melt Fracture: Ho se tloaelehe holim'a filimi e bakoang ke khatello e phahameng ea ho kuta ka lefung, e leng se bakang ponahalo e thata kapa ea wavy.

• Li-gel le Li-Fisheyes: Likaroloana tsa polymer tse sa arohaneng kapa litšila tse hlahang e le liphoso tse nyenyane, tse bonaletsang kapa tse opaque filiming.

Hangata mathata ana a hloka ho fokotsa lebelo la tlhahiso, ho eketsa litšila tsa thepa, 'me ho hloka hore ho be le ts'ebetso e eketsehileng ea basebetsi, e leng se fokotsang katleho ka kakaretso. Tšebeliso ea leano la li-additives, haholo-holo li-anti-blocking agents, li bapala karolo ea bohlokoa ho fokotsa litaba tsena le ho ntlafatsa ts'ebetso ea tlhahiso.
