Njira yonse yopangira mabotolo opangidwa ndi blow-mold (potenga njira imodzi yopangira blow-mold ya jakisoni)
Mfundo yaikulu ndi kuyika jekeseni parison kenako n’kuitambasula nthawi yomweyo ndikuipukutira pa makina omwewo. Njirayi ndi yoyenera kwambiri popanga mabotolo amadzi a PET ndi mabotolo a zakumwa omwe amagwira ntchito bwino kwambiri.
Gawo 1: Kukonzekera ndi kukonza zinthu zopangira
Zipangizo zomwe zimagwiritsidwa ntchito kwambiri ndi PET (polyethylene terephthalate), ndipo zimagwiritsidwanso ntchito pa PP, PC, ndi zina zotero.

Kuumitsa: Zipangizo zopangira PET zimakhala ndi hygroscopicity yamphamvu ndipo ziyenera kuumitsidwa mosamala kutentha kwambiri (monga 150-180℃) pogwiritsa ntchito chowumitsira chochotsa chinyezi kuti chichepetse chinyezi kufika pamlingo wotsika kwambiri (monga pansi pa 0.005%). Ichi ndiye chinsinsi chowonetsetsa kuti botololo ndi lowonekera bwino komanso silikuphwanyika.

Gawo 2: Kujambula kwa jekeseni wa parison
Ma pellets a PET ouma amayamwa mu mbiya ya makina opangira jakisoni ndikutenthedwa ndi kusungunuka kukhala pulasitiki.

Kusungunukako kumalowetsedwa mu chikombole cha parison kudzera mu sikuru yojambulira kuti apange parison yowonekera bwino yooneka ngati chubu choyesera.

Gawo la pakamwa pa botolo la parison lapangidwa mokwanira ndipo lafika pamlingo wolondola kwambiri pagawo lino.

Gawo 3: Kusintha kutentha kwa parison
Parison yotentha yopangidwayo imasamutsidwira ku siteshoni yowongolera kutentha. Panthawiyi, parison imaziziritsidwa mofanana mpaka kutentha koyenera kwambiri komwe kumakhala koyenera kutambasula (pafupifupi 90-110℃). Kufanana kwa kutentha ndiye chinsinsi chotsimikizira mtundu wa kuumba kotsatira.

Gawo 4: Kutambasula ndi kupukuta
Iyi ndi sitepe yofunika kwambiri, yomwe imamalizidwa mkati mwa chikombole chopangira zinthu.

Kutambasula kwa nthawi yayitali: Chiboliboli chopangira ma blow chimatsekedwa, ndipo ndodo yotambasula imayikidwa kuchokera pamwamba mpaka pansi mu parison kuti itambasulidwe kwa nthawi yayitali mpaka pansi pa chiboliboli.

Kupsa kwamphamvu: Nthawi yomweyo, mpweya wothamanga kwambiri (nthawi zambiri 20-40 bar) umawombedwa kuchokera pamwamba pa ndodo yotambasula, ndikuwomba parlet mozungulira ngati baluni ndikumamatira mwamphamvu kukhoma lamkati la nkhungu yozizira.

Gawo 5: Ziziritsani ndi kuyika
Botololo limasungidwa pansi pa kupanikizika mu nkhungu yopangira mpweya ndipo limaziziritsidwa kwa masekondi angapo kuti likonze mawonekedwe ake. Madzi ozizira omwe ali mkati mwa nkhunguyo amachotsa kutentha mwachangu.

Gawo 6: Tsegulani nkhungu ndikuchotsa
Chiboliboli chopangira zinthu zophwanyika chimatsegulidwa, ndipo mabotolo opangidwawo amachotsedwa ndi makina ndikupita nawo ku njira zotsatirazi.

Gawo 7: Kuwunika bwino zinthu zikatha kukonzedwa
Kudula: Chotsani chogwirira cha zinthu chowonjezera pakamwa pa botolo.

Kuzindikira

Kuzindikira mphamvu: Onetsetsani kuti kuchuluka kwa kudzaza kuli kolondola.

Kuyesa magwiridwe antchito otseka: Onetsetsani ngati kukula kwa mkamwa wa botolo ndi ulusi zili zoyenera.

Kuzindikira makulidwe a khoma: Gwiritsani ntchito choyezera makulidwe cha ultrasound kuti muwonetsetse kuti makulidwe a botolo ndi ofanana, makamaka pansi ndi mapewa.

Kuyesa kwa kuthamanga: Pa mabotolo a zakumwa zokhala ndi carbonated, mayeso amkati oletsa kuthamanga amafunika.
