Madzi a m'mabotolo akuchulukirachulukira, koma vuto la fungo lamadzi akumwa a m'mabotolo a PET lakopa chidwi cha ogula.Ngakhale sizikhudza ukhondo ndi thanzi, zimafunikirabe chidwi chokwanira kuchokera kumakampani opanga zinthu, makampani opanga zinthu ndi ogulitsa.
Madzi a mabotolo a PET amapangidwa ndi madzi, botolo la PET ndi kapu yapulasitiki.Madzi ndi opanda mtundu komanso osanunkhiza, okhala ndi zigawo zonunkhiza pang'ono zomwe zimasungunuka m'menemo, zomwe zimatulutsa kukoma kosasangalatsa zikadyedwa.Nanga fungo la m’madzi limachokera kuti?Pambuyo pofufuza komanso kuyezetsa kwambiri, anthu afika pachimake: Kuphatikiza pa zinthu zotsalira pakutsuka mabotolo ndi mankhwala ophera tizilombo toyambitsa matenda, fungo la m'madzi makamaka limachokera ku zinthu zoyikapo.Ziwonetsero zazikulu ndi izi:
1. Fungo la zida zoyikapo
Ngakhale kuti zotengerazo zimakhala zopanda fungo kutentha kwachipinda, kutentha kumakhala kopitilira 38°C kwa nthawi yayitali, tinthu tating'ono tating'ono tating'onoting'ono tazinthu zoyikamo timakonda kusinthasintha ndikusamukira m'madzi, ndikupangitsa fungo.Zida za PET ndi zida za HDPE zopangidwa ndi ma polima zimakhudzidwa kwambiri ndi kutentha.Nthawi zambiri, kutentha kukakhala kokwera, fungo limakulirakulira.Popeza ena sing'anga ndi otsika maselo zinthu kukhala polima, pa kutentha, izo volatilizes fungo kuposa polima.Pewani mayendedwe ndi kusungira pansi pa kutentha kwambiri kuti mupewe kutulutsa fungo.
2. Kuwonongeka kwa zowonjezera mu botolo la zipangizo zopangira
Cholinga chachikulu chowonjezera mafuta ndikuwongolera kutsegulira kwa kapu ya botolo ndikupangitsa kuti ogula azimwa mosavuta;kuwonjezera wothandizira kumasula kuti athandize kutulutsa kosalala kwa kapu kuchokera ku nkhungu popanga kapu;kuwonjezera mtundu masterbatch kusintha mtundu wa kapu ndi kusiyanitsa maonekedwe a mankhwala.Zowonjezera izi nthawi zambiri zimakhala ndi ma amides osadzaza mafuta, momwe chomangira chapawiri C = C chimapangidwa mosavuta ndi okosijeni.Ngati atakumana ndi kuwala kwa ultraviolet, kutentha kwambiri, ndi ozoni, chomangira chapawirichi chingatsegulidwe kupanga chisakanizo chowonongeka: mafuta acids saturated ndi unsaturated mafuta acids, acetaldehyde, carboxylic acid, ndi hydroxides, ndi zina zotero, zomwe zimatha kusungunuka mosavuta m'madzi ndikupanga zosiyana. zokonda.ndi fungo.
3. Zotsalira za fungo zomwe zimapangidwa panthawi yopanga kapu
Zomwe zimagwiritsidwa ntchito popanga zipewazo zimawonjezeredwa ndi zowonjezera monga mafuta odzola.Kupanga zipewa kumaphatikizapo njira monga kutenthetsa ndi kusonkhezera kwamakina othamanga kwambiri.Fungo chifukwa cha kukonza kumakhalabe mu chivindikiro ndipo pamapeto pake limasamukira m'madzi.
Monga wopanga kapu ya botolo lodziwika bwino, Mingsanfeng Cap Mold Co., Ltd. amapatsa makasitomala mayankho a kapu ya botolo kuphatikiza mapangidwe, kafukufuku ndi chitukuko, kupanga, kugulitsa ndi ntchito.
