Isingeniso: Uma sithatha ibhodlela le-shampoo evamile, kuzoba ne-PET logo ngaphansi kwebhodlela, okusho ukuthi lo mkhiqizo ibhodlela le-PET. Amabhodlela e-PET asetshenziswa kakhulu embonini yokuwasha nokunakekela futhi anamandla amakhulu. Kulesi sihloko, sethula ikakhulukazi ibhodlela le-PET njengesitsha sepulasitiki.
Amabhodlela e-PET yizitsha zepulasitiki ezenziwe nge-PETimpahla yepulasitikingokusebenzisa isinyathelo esisodwa noma izinyathelo ezimbili. Ipulasitiki ye-PET inezici zesisindo esilula, ukukhanya okuphezulu, ukumelana nomthelela futhi akulula ukuphuka.
Inqubo yokukhiqiza
1. Qonda i-preform
I-preform ingumkhiqizo owenziwe ngomjovo. Njengomkhiqizo ophakathi oqediwe ophakathi nendawo wokubumba kwe-biaxial stretch blow blown okulandelayo, ibhodlela le-preform seliqediwe ngesikhathi sesiteji sokubumba umjovo, futhi usayizi wawo ngeke ushintshe ngesikhathi sokushisa nokwelula/ukushaywa. Ubukhulu, isisindo, nokuqina kodonga lwe-preform yizici okudingeka sizinake kakhulu lapho sishaya amabhodlela.
A. Isakhiwo sombungu webhodlela
B. Ukubumba umbungu webhodlela
2. Ukubumba ibhodlela le-PET
Indlela yesinyathelo esisodwa
Inqubo yokuqedela umjovo, ukwelula nokuphephetha emshinini owodwa ibizwa ngokuthi indlela yesinyathelo esisodwa. Indlela yesinyathelo esisodwa ukwenza ukwelula nokufutha ngemuva kokuthi i-preform ipholile ngemuva kokubunjwa komjovo. Izinzuzo zayo eziyinhloko ukonga amandla, ukukhiqiza okuphezulu, akukho msebenzi wezandla kanye nokunciphisa ukungcola.
Indlela enezinyathelo ezimbili
Indlela yezinyathelo ezimbili ihlukanisa umjovo kanye nokunwebeka nokuphephetha, futhi ikwenza emishinini emibili ngezikhathi ezihlukene, eyaziwa nangokuthi inqubo yokwelula umjovo kanye nenqubo yokufutha. Isinyathelo sokuqala siwukusebenzisa umshini wokubumba umjovo ukuze ujove i-preform. Isinyathelo sesibili ukushisisa kabusha i-preform yezinga lokushisa legumbi bese welula futhi uyivuthele ebhodleleni. Inzuzo yendlela yezinyathelo ezimbili ukuthenga i-preform yokubunjwa kokushaywa. Inganciphisa ukutshalwa kwezimali (ithalente nemishini). Ivolumu ye-preform incane kakhulu kunebhodlela, elilungele ukuthuthwa nokugcinwa. I-preform ekhiqizwa ngenkathi engasebenzi ingavuthelwa ebhodleleni ngenkathi ephezulu.
3. Inqubo yokubumba ibhodlela le-PET
1. PET impahla:
I-PET, i-polyethylene terephthalate, ebizwa ngokuthi i-polyester. Igama lesiNgisi yi-Polyethylene Terephthalate, ekhiqizwa ukusabela kwe-polymerization (i-condensation) yezinto ezimbili zokusetshenziswa kwamakhemikhali: i-terephthalic acid PTA (terephthalic acid) ne-ethylene glycol EG (ethylicglycol).
2. Ulwazi olujwayelekile mayelana nomlomo webhodlela
Umlomo webhodlela unobubanzi obungu-Ф18, Ф20, Ф22, Ф24, Ф28, Ф33 (ohambisana nosayizi we-T womlomo webhodlela), futhi imininingwane yentambo ngokuvamile ingahlukaniswa ibe: 400, 410, 415 (okuhambisana nenombolo intambo iyajika). Ngokujwayelekile, u-400 uwukuphenduka kwentambo engu-1, u-410 uwu-1.5 ojikayo, kanti u-415 uwukujika kwentambo oku-2 okuphezulu.
3. Umzimba webhodlela
Amabhodlela e-PP kanye ne-PE ngokuvamile anemibala eqinile, i-PETG, i-PET, i-PVC ibonakala kakhulu, noma inemibala futhi isobala, inomuzwa wokuguquguquka, futhi imibala eqinile ayivamile ukusetshenziswa. Amabhodlela e-PET nawo angafuthwa. Kunephuzu eliyiconvex ezansi ebhodleleni elibunjwe ngokushaywa. Kukhanya kakhudlwana ngaphansi kokukhanya. Kukhona umugqa wokubopha phansi ebhodleleni elijovwe ngokufutheka.
4. Ukufanisa
Imikhiqizo esemqoka ehambisanayo yamabhodlela okuqhuma amapulaki angaphakathi (ajwayele ukusetshenziselwa izinto ze-PP ne-PE), amakepisi angaphandle (ajwayele ukusetshenziselwa i-PP, i-ABS ne-acrylic, abuye afakwe ngogesi, ne-electroplated aluminium, esetshenziswa kakhulu ukwenza i-spray toner), ikhava yekhanda lephampu. (ejwayele ukusetshenziselwa i-essence nelotion), amakepisi antantayo, ama-flip cap (ama-flip caps namakepisi antantayo asetshenziswa kakhulu emigqeni emikhulu yansuku zonke yamakhemikhali), njll.
Isicelo
Amabhodlela e-PET asetshenziswa kakhulu embonini yezimonyo,
ikakhulukazi embonini yokuwasha nokunakekela,
kufaka phakathi i-shampoo, amabhodlela ejeli yokugeza, i-toner, amabhodlela okukhipha izimonyo, njll.
zonke zishaywa.
Ukuthenga okucatshangelwayo
1. I-PET ingenye yezinto ezitholakalayo zamabhodlela okuqhuma. Kukhona futhi amabhodlela e-PE (imibala ethambile, eqinile kakhulu, eyakha ngesikhathi esisodwa), amabhodlela e-PP (imibala eqinile, eqinile, eyakha ngesikhathi esisodwa), amabhodlela e-PETG (ukukhanya okungcono kune-PET, kodwa hhayi ngokuvamile. esetshenziswa eShayina, izindleko eziphezulu, imfucumfucu ephezulu, ukwakheka kwesikhathi esisodwa, izinto ezingaphinde zisetshenziswe), amabhodlela e-PVC aqhumayo (anzima, awahambisani nemvelo, abonisa ngale kune-PET, kodwa akhanya kune-PP ne-PE)
2. Imishini enesinyathelo esisodwa iyabiza, imishini enezinyathelo ezimbili ishibhile
3. Isikhunta sebhodlela le-PET ishibhile.
