PET Sheet Production Process le Mathata a Tloaelehileng

Selelekela:

Lipampiri tse pepeneneng tsa PET li bapala karolo ea bohlokoa indastering ea sejoale-joale, haholo liphutheloana tsa lijo. Leha ho le joalo, ts'ebetso ea tlhahiso le litaba tse tloaelehileng tse amanang le maqephe a PET ke lintlha tsa bohlokoa tse amang boleng le katleho ea tlhahiso. Sengoliloeng sena se tla shebana le ts'ebetso ea tlhahiso le litaba tse tloaelehileng tsa maqephe a pepenene a PET, ho fana ka tharollo ho thusa babali ho utloisisa le ho sebetsana le mathata a tlhahiso ea lisebelisoa tsa PET.

I. Tlhaloso le Tšebeliso ea PET

Lipampiri tse bonaletsang tsa PET ke lilakane tsa polasetiki tse bonaletsang tse entsoeng ka resin ea Polyethylene Terephthalate (PET). PET resin ke thepa e tloaelehileng ea polasetiki e tsebahalang ka ho hanyetsa mocheso o phahameng, khanyetso ea lik'hemik'hale, le matla a maholo a mochini. Lipampiri tsena tse pepeneneng li bonts'a pepenene e phahameng le thepa e phahameng ea 'mele, e etsang hore e sebelisoe haholo lits'ebetsong tse fapaneng. Haholo-holo indastering ea ho paka, lipampiri tse pepeneneng tsa PET li ratoa ka lebaka la ponahalo ea tsona e ntle haholo, e tšoarellang le ho bōptjoa. Liindastering tse kang lijo, lino le meriana, maqephe a PET a sebelisoa hangata ho etsa lijana tsa ho paka tse pepeneneng joalo ka libotlolo le linkho. Ponaletso ea bona e lumella ho bonts'a likahare tsa sehlahisoa ha e ntse e fana ka tiiso e ntle le ho hanyetsa ho bola ho boloka boleng ba sehlahisoa ka nepo. Ntle le moo, lipampiri tse pepeneneng tsa PET li fumana lits'ebetso likarolong tse ling tse joalo ka mekotla ea lihlahisoa tsa elektroniki le lisebelisoa tse hatisitsoeng, tse fanang ka liphutheloana tsa boleng bo holimo le ponts'o ea lihlahisoa tse fapaneng.

II. Mokhoa oa ho hlahisa PET

A. Tokisetso ea Lintho tse tala
Tlhahiso ea maqephe a PET e qala ka ho lokisetsa thepa e tala. Sena se kenyelletsa ho khetha resin ea PET e loketseng ho netefatsa hore sehlahisoa se na le thepa e ntle ea pepeneneng. Ho feta moo, li-additives tse kang li-toughening agents le stabilizer li entsoe ka nepo ho latela litlhoko tsa sehlahisoa ho matlafatsa ts'ebetso le botsitso.

B. Mokhoa oa Tlhahiso
Mokhoa oa ho etsa lipampiri tsa PET hangata o kenyelletsa ho ohla, ho hlahisa le ho bopa. Qalong, resin ea PET e futhumatsoa hore e be boemong ba ho qhibiliha ebe e ntšoa ka likhoele ho sebelisa extruder. Kamora moo, likhoele tse fetisitsoeng tsa PET li fetisoa hape ka mochini ho etsa maqephe a masesaane. Qetellong, maqephe a PET a fetisitsoeng aa pholile ebe a bōptjoa ho sebelisoa hlobo ho fihlela sebopeho le boholo ba sehlahisoa sa ho qetela.

C. Post-Processing
Kamora tlhahiso, lipampiri tse pepeneneng tsa PET li etsoa ka mor'a ts'ebetso ho ntlafatsa ts'ebetso ea tsona le boleng ba pono. Sena se kenyelletsa mehato ea ho pholisa, ho otlolla le ho itšeha. Qalong, maqephe a PET a bōpiloeng a pholile ho tiisa sebopeho sa bona. Joale, ho itšetlehile ka litlhoko, lipampiri tse pholileng lia otlolla ho ntlafatsa thepa ea tsona ea 'mele. Qetellong, maqephe a PET a otlolohileng a khaoloa ho isa litekanyo tse lakatsehang ho fumana lihlahisoa tsa ho qetela.

III. Mathata a Tloaelehileng le Litharollo

A. Mathata a Boleng ba Sefahleho

• 1. Bubbles:  Li-bubble ke taba e tloaelehileng ea boleng bo holimo nakong ea tlhahiso ea maqephe a pepenene a PET. Ho fokotsa sebopeho sa bubble, ho lokisa liparamente tsa ts'ebetso ea extrusion joalo ka ho theola mocheso oa extrusion le ho eketsa khatello ea extrusion ho ka ntlafatsa phallo ea thepa le ho thibela sebopeho sa bubble.
• 2. Burr:  Li-Burrs li ama ponahalo le boleng ba lakane mme ka hona mehato e lokela ho nkuoa ho fokotsa moloko oa bona. Ho ntlafatsa moralo oa lefu le ho eketsa nako ea ho pholile ho ka fokotsa li-burrs le ho ntlafatsa boreleli ba sehlahisoa.
• 3. Moholi oa metsi:  Nakong ea ts'ebetso ea extrusion, bohloeki ba lisebelisoa tsa extruder le tikoloho ke tsa bohlokoa ho qoba ho hlahisa moholi oa metsi. Ho boloka lisebelisoa tsa extruder li hloekile le ho boloka tikoloho e hloekile nakong ea ts'ebetso ea extrusion ho ka fokotsa ka nepo ho hlaha ha moholi oa metsi.

B. Mathata a Ts'ebetso ea 'Mele

• 1. Matla a sa Lekaneng:  Haeba maqephe a PET a haelloa ke matla, tekanyo e ntseng e eketseha ea ho otlolla nakong ea ho otlolla e ka matlafatsa matla a lakane. Ho feta moo, ho lokisa liforomo tsa thepa le ho eketsa li-agent tse matlafatsang ho ka ntlafatsa matla.
• 2. Ho hanyetsana ha Abrasion e Fosahetseng:  Ho khetha resin ea PET e nang le khanyetso e ntle ea abrasion kapa ho roala bokaholimo ka likarolo tse hananang le abrasion ho ntlafatsa ka nepo khanyetso ea abrasion ea sheet. Ho eketsa li-additives tse nepahetseng nakong ea tlhahiso ho matlafatsa khanyetso ea abrasion ea sheet.
• 3. Ho hanyetsana ha khatello e fokolang:  Ho ntlafatsa likarolo tsa ts'ebetso ea extrusion joalo ka khatello e ntseng e eketseha ea ho bopa ho ka ntlafatsa ho hanyetsa ha khatello ea maqephe a pepenene a PET. Bakeng sa lihlahisoa tse hlokang matla a phahameng, ho nahana ka tšebeliso ea lisebelisoa tse matlafatsang kapa ho eketsa botenya ba sehlahisoa ho eketsa khanyetso ea khatello.

C. Phetoho ea Mekhoa ea Ts'ebetso

• 1. Taolo ea Mocheso:  Taolo e nepahetseng ea mocheso nakong ea tlhahiso ea maqephe a PET e bohlokoa ho netefatsa boleng ba sehlahisoa. Ka ho lokisa lisebelisoa tsa ho futhumatsa le ho pholisa le ho ntlafatsa mokhoa oa ho laola mocheso oa li-extruder, litaba tse bakoang ke mocheso o phahameng haholo kapa o tlaase li ka qojoa ka katleho.
• 2. Phetoho ea Khatello: Ho fetola maemo a khatello ea li-extruder ho latela litšobotsi tsa PET resin le litlhoko tsa sehlahisoa ho ntlafatsa ts'ebetso ea tlhahiso ka nepo, ho ntlafatsa boleng ba sehlahisoa le botsitso.
• 3. Ntlafatso ea Lebelo:  Ho laola lebelo la extrusion ho bohlokoa bakeng sa ho netefatsa boleng ba sehlahisoa le katleho ea tlhahiso. Ka ho fetola lebelo la ts'ebetso ea li-extruder ka nepo, boholo ba sehlahisoa le boleng ba bokaholimo li ka fihlela litlhoko ha li ntse li ntlafatsa katleho ea tlhahiso.

IV. Libaka tsa Kopo tsa PET

Lipampiri tsa PET li na le menyetla e mengata indastering ea ho paka, haholo lijong, lino le meriana. Ka litlhoko tse ntseng li eketseha tsa bareki bakeng sa boleng ba sehlahisoa le ponahalo, lijana tsa ho paka tsa PET tse pepeneneng li tla ba tse tloaelehileng. Liphutheloana tse pepeneneng ha li bontše feela chebahalo le boleng ba lihlahisoa empa hape li ntlafatsa boipiletso ba tsona ba thekiso.

Tabeng ena,tmechine ea hermoforming phetha karolo ea bohlokoa. Theknoloji ea thermoforming e futhumatsa maqephe a PET mochesong o qhibilihang ebe e a bopa hore e be libopeho tse fapaneng tsa lijana tsa ho paka tse pepeneneng tse sebelisang hlobo. Mechini ea rona e tsoetseng pele ea thermoforming e ithorisa ka bokhoni bo sebetsang le bo tsitsitseng ba tlhahiso, e fihlelang litlhoko tse fapaneng tsa maqephe a pepeneneng a PET ho latela litlhaloso le libopeho.

Re ikemiselitse ho fa bareki litharollo tsa boleng bo holimo, tse etselitsoeng thermoforming ho fihlela litlhoko tsa ho paka liindasteri tse fapaneng. Ebang ke ka ho paka lijo, ho paka lino, kapa ho paka meriana, ronamechine ea polasetiki ea thermoformingfana ka ts'ehetso e tšepahalang ea tlhahiso, ho thusa lihlahisoa ho hlahella 'marakeng.

Qetello
Qetellong, maqephe a pepenene a PET a phetha karolo ea bohlokoa e le thepa ea bohlokoa ea ho paka liindastering tsa sejoale-joale. Ka ho utloisisa ka botlalo ts'ebetso ea bona ea tlhahiso le litaba tse tloaelehileng le ho hlahisa theknoloji e tsoetseng pele ea thermoforming, re ka fa bareki litharollo tse ikhethileng tsa boleng bo holimo. Re labalabela ho sebelisana le bareki ho theha bokamoso bo khanyang le ho fumana katleho e kholo indastering ea ho paka.
