Uma sithatha ibhodlela le-shampoo elisetshenziswa kakhulu, kuzoba nophawu lwe-PET phansi kwebhodlela, okusho ukuthi lo mkhiqizo uyibhodlela le-PET. Amabhodlela e-PET asetshenziswa kakhulu embonini yokuwasha nokunakekela, ikakhulukazi ngobukhulu.
一, Incazelo Yomkhiqizo
Amabhodlela e-PET enziwe ngeIpulasitiki ye-PETfuthi zicutshungulwa ngezinqubo zesinyathelo esisodwa noma ezimbili ukuze kutholakale izitsha zepulasitiki.
Ipulasitiki ye-PET inezici zobukhulu obulula, ukucaca okuphezulu, ukumelana nokushayisana futhi akulula ukuyiphula.
Inqubo yokukhiqiza
1. Qonda i-preform
I-preform ingumkhiqizo obunjiwe ngomjovo. Njengomkhiqizo oqediwe phakathi nendawo wokubumba okunwebekayo kwe-biaxial okulandelayo, intamo ye-preform iqediwe ngesikhathi sesigaba sokubumba ngomjovo, futhi usayizi wayo ngeke ushintshe ngesikhathi sokushisa nokwelula/ukushaya. Usayizi, isisindo, kanye nobukhulu bodonga lwe-preform yizinto okudingeka siziqaphele kakhulu lapho sivuthela amabhodlela.
Isakhiwo sangaphambi kokwenza
Ukubumba kusengaphambili
2. Ukubumba amabhodlela e-PET
Indlela yesinyathelo esisodwa
Inqubo yokuqedela ukujova, ukwelula kanye nokufutha emshinini owodwa ibizwa ngokuthi indlela yesinyathelo esisodwa. Indlela yesinyathelo esisodwa ukwenza ukwelula kanye nokufutha ngemva kokuba i-preform isipholile ngemva kokubumba ngomjovo. Izinzuzo zayo eziyinhloko ukonga amandla, ukukhiqiza okuphezulu, ukungasebenzi ngezandla kanye nokunciphisa ukungcola.
Indlela enezinyathelo ezimbili
Indlela enezinyathelo ezimbili ihlukanisa ukubumba ngomjovo kanye nokwelula futhi ikwenze emishinini emibili ngezikhathi ezahlukene. Ibizwa nangokuthi inqubo yokubumba ngomjovo. Isinyathelo sokuqala ukusebenzisa umshini wokubumba ngomjovo ukufaka i-preform. Isinyathelo sesibili ukuphinda ufudumale i-preform ekushiseni kwegumbi bese uyivula nge-stretch ibe yibhodlela. Inzuzo yendlela enezinyathelo ezimbili ukuthi i-preform ingathengwa ukuze ibumbe nge-blow. Inganciphisa ukutshalwa kwezimali (ithalente kanye nemishini). Umthamo we-preform mncane kakhulu kunowebhodlela, okulula ukuthuthwa nokugcinwa. I-preform ekhiqizwa ngesikhathi sokuphumula ingavuthelwa ebhodleleni ngesikhathi sonyaka esiphezulu.
3. Inqubo yokubumba amabhodlela e-PET
Izinto kanye nesakhiwo
1. Izinto ze-PET
I-PET, i-polyethylene terephthalate, ebizwa ngokuthi i-polyester. Igama lesiNgisi yi-Polyethylene Terephthalate, ekhiqizwa yi-polymerization reaction (condensation) yezinto ezimbili zokusetshenziswa kwamakhemikhali, i-terephthalic acid PTA (terephthalic acid) kanye ne-ethylene glycol EG (ethylicglycol).
2. Ulwazi oluvamile mayelana nomlomo webhodlela
Umlomo webhodlela unobubanzi obungu-Ф18, Ф20, Ф22, Ф24, Ф28, Ф33 (okuhambisana nosayizi ongu-T womlomo webhodlela), futhi imininingwane yentambo ngokuvamile ingahlukaniswa ibe: 400, 410, 415 (okuhambisana nenani lokujika kwentambo). Ngokuvamile, u-400 uwukujika kwentambo oku-1, u-410 uwukujika kwentambo oku-1.5, kanti u-415 uwukujika kwentambo oku-2 okuphezulu.
3. Umzimba webhodlela
Amabhodlela e-PP kanye ne-PE anemibala eqinile, izinto ze-PETG, PET, PVC zivame ukuba sobala, noma zibe nombala ocacile, zinomuzwa wokukhanya, futhi imibala eqinile ayisetshenziswa kakhulu. Amabhodlela e-PET nawo angafuthwa. Kukhona ichashaza eliyindilinga phansi kwebhodlela elibunjwe nge-blow. Likhanya kakhulu ngaphansi kokukhanya. Kukhona umugqa wokubopha phansi kwebhodlela elifakwe nge-blow.
4. Izesekeli ezisekelayo
Izesekeli eziyinhloko ezisekelayo zamabhodlela okuqhuma yizixhumi zangaphakathi (ezivame ukusetshenziswa ezintweni ze-PP ne-PE), izixhumi zangaphandle (ezivame ukusetshenziswa kwi-PP, i-ABS kanye ne-acrylic, eziphinde zifakwe i-electroplated, kanye ne-aluminium efakwe i-electroplated, ezivame ukusetshenziswa kuma-spray toner), izixhumi zangaphandle ze-pump head (ezivame ukusetshenziswa kuma-essence nama-lotion), izixhumi ezintantayo, izixhumi ezintantayo (izixhumi ezintantayo kanye nezixhumi ezintantayo zisetshenziswa kakhulu emigqeni yamakhemikhali yansuku zonke ehamba ngobuningi), njll.
Izinhlelo zokusebenza zezimboni
Amabhodlela e-PET asetshenziswa kabanzi embonini yezimonyo, ikakhulukazi embonini yokuhlanza, okuhlanganisa i-shampoo, amabhodlela e-shower gel, i-toner, amabhodlela okususa izimonyo, njll., konke okupheshulwa futhi kukhiqizwe.
五、Izinto okufanele uzicabangele ngokuthenga
1. Amabhodlela okufutha angenziwa ngezinto zokwakha, i-PET ingenye yazo kuphela, kukhona namabhodlela okufutha e-PE (athambile, anemibala eqinile, abumba kanye), amabhodlela okufutha e-PP (aqinile, anemibala eqinile, abumba kanye), amabhodlela okufutha e-PETG (abonakala kangcono kune-PET, kodwa angasetshenziswa njalo eShayina, izindleko eziphezulu, imfucuza ephezulu, abumba kanye, izinto ezingaphinde zisetshenziswe), amabhodlela okufutha e-PVC (aqinile, awanabo ubungane nemvelo, awabonakali kangako kune-PET, kodwa akhanya kangcono kune-PP ne-PE)
2. Imishini yesinyathelo esisodwa ibiza kakhulu, eyezinyathelo ezimbili ishibhile kakhulu
3. Ibhodlela le-PETizikhunta zishibhile.
4. Izinkinga nezixazululo ezijwayelekile zekhwalithi, bheka ividiyo
