Uma sithatha ibhodlela le-shampoo elivame ukusetshenziswa, kuzoba ne-PET logo ngaphansi kwebhodlela, okusho ukuthi lo mkhiqizo ibhodlela le-PET. Amabhodlela e-PET asetshenziswa kakhulu embonini yokuwasha nokunakekela, ikakhulukazi ngomthamo omkhulu.
一、Incazelo Yomkhiqizo
Amabhodlela e-PET akhiweIpulasitiki ye-PETfuthi acutshungulwa ngesinyathelo esisodwa noma izinyathelo ezimbili ukuze kutholwe iziqukathi zepulasitiki.
Ipulasitiki ye-PET inezici zesisindo esilula, ukukhanya okuphezulu, ukumelana nomthelela futhi akulula ukuphuka.
二、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.

Ukubunjwa kwangaphambili
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 nokubunjwa kwe-stretch blow bese ikwenza emishinini emibili ngezikhathi ezihlukene. Ibizwa nangokuthi inqubo yokubumba i-injection stretch blow. Isinyathelo sokuqala siwukusebenzisa umshini wokubumba umjovo ukuze ujove i-preform. Isinyathelo sesibili ukushisisa kabusha i-preform ekushiseni kwegumbi bese welula uyishaye ebhodleleni. Inzuzo yendlela yezinyathelo ezimbili ukuthi i-preform ingathengwa ngokubunjwa kokushaywa. Inganciphisa ukutshalwa kwezimali (ithalente nemishini). Ivolumu ye-preform incane kakhulu kunebhodlela, elilungele ukuthuthwa nokugcinwa. I-preform ekhiqizwa ngenkathi engasebenzi ingavuthelwa ebhodleleni ngenkathi ephezulu.

三、 Izinto kanye nesakhiwo
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, izinto ze-PVC zisobala kakhulu, noma ukukhanya okunemibala, kunomqondo wokuguquguquka, nemibala eqinile ayivamisile ukusetshenziswa. Amabhodlela e-PET nawo angafuthwa. Kunechashaza eliyi-convex ngaphansi kwebhodlela elibunjwe ngokushaywa. Kukhanya kakhudlwana ngaphansi kokukhanya. Kukhona umugqa wokubopha phansi ebhodleleni elijovwe ngokufutheka.
4. Izesekeli ezisekelayo
Izesekeli eziyinhloko ezisekela amabhodlela okuqhuma amapulaki angaphakathi (avame ukusetshenziselwa izinto ze-PP kanye ne-PE), amakepisi angaphandle (avame ukusetshenziselwa i-PP, i-ABS ne-acrylic, abuye afakwe ngogesi, kanye ne-electroplated aluminium, esetshenziswa kakhulu ukwenza ama-spray toner), ikhanda lephampu langaphandle. amakhava (okujwayele ukusetshenziselwa ama-essence nama-lotions), amakepisi antantayo, ama-flip cap (ama-flip cap namakepisi antantayo asetshenziswa kakhulu emigqeni yamakhemikhali yansuku zonke esakazwa kakhulu), njll.
四、Izinhlelo zokusebenza zemboni
Amabhodlela e-PET asetshenziswa kakhulu embonini yezimonyo, ikakhulukazi embonini yokuhlanza, okuhlanganisa i-shampoo, amabhodlela ejeli eshaweni, i-toner, amabhodlela okukhipha izimonyo, njll., wonke ashaywa futhi akhiqizwa.
五、Ukuthenga okucatshangelwayo
1. Amabhodlela afuthayo angenziwa ngezinto zokwakha, i-PET ingenye yazo, kukhona namabhodlela afuthayo e-PE (imibala ethambile, eqinile, eyakha isikhathi esisodwa), amabhodlela afutha i-PP (anzima, imibala eqinile, ukwakheka kwesikhathi esisodwa. ), amabhodlela afuthayo e-PETG (ukukhanya okungcono kune-PET, kodwa okungavamile ukusetshenziswa e-China, izindleko eziphezulu, imfucuza ephezulu, ukwakheka ngesikhathi esisodwa, izinto ezingasetshenziswa kabusha), amabhodlela aphefumulayo e-PVC (anzima, awahambisani nemvelo, angabonakali kakhulu kune-PET, kodwa ukukhanya okungcono kune-PP ne-PE)
2. Imishini yesinyathelo esisodwa iyabiza, izinyathelo ezimbili zishibhile
3. Ibhodlela le-PETisikhunta ishibhile.
4. Izinkinga ezijwayelekile zekhwalithi nezixazululo, bheka ividiyo
