Poly Cyclohexylenedimethylene Terephthalate glycol-modified, yotchedwa PCT-G pulasitiki ndi co-polyester yomveka bwino. PCT-G polima ndiyoyenera makamaka pamapulogalamu omwe amafunikira zotulutsa zotsika kwambiri, zomveka bwino komanso kukhazikika kwapamwamba kwambiri kwa gamma. Zinthuzo amadziwikanso ndi katundu mkulu zimakhudza, zabwino yachiwiri processing katundu mongaultrasonic kuwotcherera, kukana mwamphamvu kukanda kumagwiritsidwa ntchito kwa mabotolo a ana, makapu a danga , Pulasitiki yabwino kwambiri ya soymilk ndi juicer.
Chifukwa chofuna anthu kukhala ndi moyo wabwino komanso thanzi, zofunikira zoteteza zachilengedwe pamsika wazinthu zapulasitiki zikuchulukiranso. Mwachitsanzo, BPA idzapangidwa pambuyo pa hydrolysis ya PC. Kafukufuku waposachedwa wasonyeza kuti anthu (kuphatikiza nyama) amadya kwanthawi yayitali kuchuluka kwa BPA ndizotheka kukhala ndi zotsatira zoyipa pa ubereki ndikuwononga kuchuluka kwa kugonana. Chifukwa chake, mayiko ndi madera ena aletsa kapena kuletsa PC. PCTG ndi mtundu watsopano wazinthu zoteteza chilengedwe zomwe zimagonjetsa vutoli. Ilinso ndi kuwotcherera kwabwino kwa ultrasonic. Magwiridwe, malinga ndi mankhwala kukula, Ndi bwino kugwiritsa ntchito 20khz mkulu-mphamvu akupanga kuwotcherera kwa kuwotcherera.
2. Botolo lamasewera lakunja lakunja nthawi zambiri limatenga botolo la jekeseni la PC, mawonekedwe amitundu iwiri, osanjikizana mkati, ultrasonic welding, palibe kutayikira kwamadzi, madzi otentha mkati mwake samatulutsa nthunzi, koma chifukwa PC ili ndi vuto la BPA. , PCTG imagwiritsidwa ntchito m'malo mwa PC kuti ipange thupi la botolo, ndipo mphamvu ndi kuwonekera kwa botolo zingathe kusungabe mlingo wa botolo la PC.
Thupi la botolo lamadzi lamasewera la PCTG limatenga pulasitiki yansanjika ziwiri, ndipo malo owotcherera amatengera mawonekedwe a convex-groove. The kuwotcherera pamwamba ndi welded ndi akupanga kuwotcherera makina. Kuwotcherera pamwamba ndi koyera komanso kokongola.
Kapu yamadzi yamasewera a PCTG yowotcherera iyenera kutenthedwa kwa nthawi yayitali pa kutentha kwakukulu kwa madigiri 100, ndipo imatha kupirira kuyeretsa mobwerezabwereza kwa maola angapo mu chotsuka chotsuka chotsuka ndi kutsitsi kwambiri komanso kutentha kwambiri. Chobowocho sichitulutsa madzi kapena nthunzi; kukana kukhudza, palibe ming'alu, komanso nthawi yayitali Sizisintha mtundu zikagwiritsidwa ntchito. Mukachiphwanya mwamphamvu ndi nyundo, samalani kuti malo omwe amawotcherera atsekedwa kwathunthu.
