Kudziwa pang'ono pakupanga jakisoni wa botolo la PET preform.

Ma preforms a botolo la PET ndizomwe zimapangidwira jekeseni, zosavuta kunyamula, zopangidwa ndi pulasitiki, zokhala ndi mawonekedwe ofananirako komanso kutsekereza kwabwino.Ndizinthu zapakatikati zamabotolo apulasitiki ndi migolo yamafuta.Pansi pa kutentha ndi kupanikizika kwina, nkhungu imadzazidwa ndi zipangizo, ndipo pansi pa makina opangira jekeseni, imasinthidwa kukhala preform ya botolo ndi makulidwe ena ndi kutalika kofanana ndi nkhungu.Polyethylene terephthalate ndiye mtundu wofunikira kwambiri wa polyester ya thermoplastic.Dzina lake la Chingerezi ndi Polythylene terephthalate, yofupikitsidwa ngati PET kapena PETP (yotchedwa PET), yomwe imadziwika kuti polyester resin.Ndi polima condensation wa terephthalic acid ndi ethylene glycol.Pamodzi ndi PBT, onse pamodzi amatchedwa thermoplastic polyester, kapena saturated polyester.PET ndi polima yoyera yamkaka kapena yachikasu yowoneka bwino komanso yosalala komanso yonyezimira.Ili ndi kukana kwabwino, kukana kutopa, kukana kukangana ndi kukhazikika kwa mawonekedwe, kuvala pang'ono komanso kuuma kwakukulu, ndipo imakhala ndi kulimba kwakukulu pakati pa thermoplastics;zabwino zotchinjiriza magetsi, zomwe zimakhudzidwa pang'ono ndi kutentha, koma kukana kwa corona.Zopanda poizoni, zolimbana ndi nyengo, zosasunthika motsutsana ndi mankhwala, mayamwidwe amadzi ochepa, osamva ma asidi ofooka ndi zosungunulira za organic.

Mabotolo a PET amagwiritsidwa ntchito nthawi zambiri kulongedza, ndipo zoyikapo nthawi zambiri zimayikidwa m'magawo panthawi yamayendedwe kapena kuwerengera.Panthawiyi, tidzakambirana za kulekerera kwapakati kwa otsika kwambiri.Poyesa kukakamiza kwa botolo la PET, ikani botolo la PET pamakina awiri opingasa opingasa, yambitsani makina opondereza a botolo la PET a Suzhou Ou Instruments, ndipo mbale ziwirizo zidzakakamizidwa pa liwiro linalake loyesa.Mukatsitsa, chidacho chimangoyima ndikusunga deta.Kuyesa kwanthawi zonse kwa mabotolo a PET kumaphatikizapo kuyesa makulidwe a khoma la botolo, kuyesa kukana kupanikizika, komanso kuyesa kutopa kwa botolo.Opanga PET ali ndi madipatimenti awo owunikira.Mabotolo a PET amagwira ntchito mwamphamvu ndipo amagwiritsidwa ntchito kwambiri pazofunikira zatsiku ndi tsiku, kunyamula mankhwala tsiku lililonse ndi magawo ena.Kuyambira kukonza nkhungu kupita ku makina ndi zida, ndizosankha kwambiri.Ndi zophweka kuyamba koma zovuta kuzidziwa.Ma preforms a botolo la PET amakonzedwanso kudzera pakuwomba kuti apange mabotolo apulasitiki, kuphatikiza mabotolo omwe amagwiritsidwa ntchito popanga zodzoladzola, mankhwala, chisamaliro chaumoyo, zakumwa, madzi amchere, ma reagents, ndi zina. botolo la preform limapangidwa kudzera mu jekeseni, ndiyeno Njira yopangira mabotolo apulasitiki a PET kudzera pakuwomba.
