Isingeniso: Uma sithatha ibhodlela le-shampoo elivamile, kuzoba nophawu lwe-PET phansi kwebhodlela, okusho ukuthi lo mkhiqizo uyibhodlela le-PET. Amabhodlela e-PET asetshenziswa kakhulu embonini yokuwasha nokunakekela futhi anesisindo esikhulu. Kulesi sihloko, sethula kakhulu ibhodlela le-PET njengesitsha sepulasitiki.
Amabhodlela e-PET ayizitsha zepulasitiki ezenziwe nge-PETizinto zepulasitikingokusebenzisa ukucutshungulwa kwesinyathelo esisodwa noma ezimbili. Ipulasitiki ye-PET inezici zesisindo esilula, 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.
A. Isakhiwo se-embryo yebhodlela
B. Ukubumba umbungu ebhodleleni
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 ukujova kanye nokwelula kanye nokufutha, futhi ikwenza emishinini emibili ngezikhathi ezahlukene, eyaziwa nangokuthi inqubo yokwelula kanye nokufutha nge-injection. Isinyathelo sokuqala ukusebenzisa umshini wokubumba nge-injection ukufaka i-preform. Isinyathelo sesibili ukuphinda ufudumale i-preform yokushisa kwegumbi bese uyifutha bese uyifutha ebhodleleni. Inzuzo yendlela enezinyathelo ezimbili ukuthenga i-preform yokufutha nge-blow molding. Kunganciphisa ukutshalwa kwezimali (ithalente kanye nemishini). Umthamo we-preform mncane kakhulu kunowebhodlela, okulula ukuthuthwa kanye nokugcinwa. I-preform ekhiqizwa ngesikhathi sokuphumula ingafuthwa ebhodleleni ngesikhathi sonyaka esiphezulu.
3. Inqubo yokubumba amabhodlela e-PET
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 zamakhemikhali: i-terephthalic acid i-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, i-PETG, i-PET, i-PVC ngokuvamile iyabonakala, noma inemibala futhi iyabonakala, inomuzwa wokukhanya, futhi imibala eqinile ayisetshenziswa kakhulu. Amabhodlela e-PET nawo angafuthwa. Kukhona iphuzu eliqondile phansi kwebhodlela elibunjwe nge-blow-mold. Likhanya kakhulu ngaphansi kokukhanya. Kukhona umugqa wokubopha phansi kwebhodlela elifakwe nge-blow-mold.
4. Ukufanisa
Imikhiqizo eyinhloko ehambisanayo yamabhodlela okuqhuma ama-plug angaphakathi (avame ukusetshenziswa ezintweni ze-PP ne-PE), ama-cap angaphandle (avame ukusetshenziswa kwi-PP, i-ABS kanye ne-acrylic, futhi afakwe i-electroplated, kanye ne-aluminium efakwe i-electroplated, avame ukusetshenziswa kwi-spray toner), isembozo sekhanda lephampu (evame ukusetshenziswa kwi-essence kanye ne-lotion), ama-cap antantayo, ama-flip cap (ama-flip cap kanye nama-floating cap asetshenziswa kakhulu emigqeni yamakhemikhali yansuku zonke ehamba ngobuningi), njll.
Isicelo
Amabhodlela e-PET asetshenziswa kabanzi embonini yezimonyo,
ikakhulukazi embonini yokuwasha nokunakekela,
kufaka phakathi i-shampoo, amabhodlela e-shower gel, i-toner, amabhodlela okususa izimonyo, njll.
bonke bashaywe umoya.
Izinto okufanele uzicabangele ngokuthenga
1. I-PET ingenye yezinto ezitholakalayo zamabhodlela okuqhuma. Kukhona namabhodlela okuqhuma e-PE (athambile, anemibala eqinile, ayenza kanye), amabhodlela okuqhuma e-PP (aqinile, anemibala eqinile, ayenza kanye), amabhodlela okuqhuma e-PETG (abonakala kangcono kune-PET, kodwa angasetshenziswa njalo eShayina, izindleko eziphezulu, imfucuza ephezulu, ayenza kanye, izinto ezingaphinde zisetshenziswe), amabhodlela okuqhuma e-PVC (aqinile, angangcolisi imvelo, awabonakali kangako kune-PET, kodwa akhanya kakhulu kune-PP ne-PE)
2. Imishini yesinyathelo esisodwa ibiza kakhulu, imishini yezinyathelo ezimbili ishibhile kakhulu
3. Izikhunta zamabhodlela e-PET zishibhile.
