Chidziwitso Chogwiritsira Ntchito
Chifukwa Chake "Kuuma Koyenera" Kumalepherabe mu Mapulogalamu a TPU / TPE
Mu mapulojekiti ambiri a TPU ndi TPE, kusankha zinthu nthawi zambiri kumayamba ndi nambala imodzi: kuuma.
Ngakhale kuuma ndi kufotokozera kofunikira, nthawi zambiri kumaonedwa ngati chosinthika cha chisankho osati zotsatira zake.
Kuphweka kumeneku ndi chimodzi mwa zifukwa zomwe mapulogalamu amalephera ngakhale pamene kuuma "koyenera" kwasankhidwa.

Nkhani Yogwiritsira Ntchito
Kusankha kokhazikika pa kuuma kumachitika kawirikawiri pa ntchito zotulutsira, kupanga jakisoni, kupanga overmolding, ndi kugwiritsa ntchito zofewa.
Poyamba ntchito, zipangizo zomwe zili ndi mphamvu zofanana ndi za Shore hardness nthawi zambiri zimaonedwa kuti zimasinthasintha.
Komabe, magwiridwe antchito amunda nthawi zambiri amasiyana ngakhale kuti kuuma kofanana ndi dzina.

Zopinga Zofunika Zomwe Kuuma Sikuzitenga
- Banja la zinthu zakuthupi:
TPU (polyether vs polyester), SEBS-based TPE, ndi machitidwe ena a elastomer amachita zinthu mosiyana kwambiri pa kuuma komweko. - Khalidwe lokonza:
Kukhazikika kwa kayendedwe ka madzi, kufooka kwa madzi, ndi mphamvu yosungunuka sizimaonekera mu kuuma kwa madzi. - Kuchita zinthu motsatira nthawi:
Kukalamba, kupanikizika, kusamuka, ndi kusinthasintha kwa nthawi yayitali zimapitirira kupitirira mayeso oyamba.
Kusankha Zinthu Zofunika
Kuuma kuyenera kuonedwa ngati zotsatira za kapangidwe ndi kapangidwe kake, osati ngati njira yosankha yoyamba.
Zipangizo ziwiri zomwe zili pa Shore A imodzi zingasiyane kwambiri mu kapangidwe ka mamolekyulu, kapangidwe kake kofewa,
ndi machitidwe owonjezera, zomwe zimapangitsa kuti pakhale machitidwe osiyanasiyana enieni.

Mwachizolowezi, kuuma nthawi zambiri kumakhala chinthu chosavuta kuyerekeza, koma nthawi zambiri sikulamulira kukhazikika kwa nthawi yayitali,
kulimba kwa njira, kapena kudalirika kwa malo.

Zomwe Zimanyalanyazidwa Kawirikawiri Pachiyambi Chake
- Kuvomerezedwa kwa chitsanzo kwa nthawi yochepa sikuyimira khalidwe la utumiki wa nthawi yayitali.
- Kufanana kwa kuuma sikutanthauza kufanana kwa processing.
- Kusintha komwe kwapangidwa kuti kukwaniritse zolinga za kuuma kungasokoneze kukhazikika kwina.
Kumene Kuganizira Izi Kukugwirizana ndi Mbiri Yathu
Ntchito zomwe kuuma kumawoneka ngati chinthu chofunikira kwambiri nthawi zambiri zimayankhidwa pansi pa magulu a TPU ndi TPE.
Pamene kuuma kuyenera kulinganizidwa ndi kukhazikika kwa kukonza, kukana ukalamba, kapena zopinga zingapo za magwiridwe antchito,
Kuwunikanso nkhani zambiri nthawi zambiri kumafunika.

Kuwunikanso nkhani zambiri nthawi zambiri kumafunika.
Pa ntchito zokhudzana ndi kukhazikika kwa nthawi yayitali, kusasinthasintha kwa ntchito, kapena zopinga zingapo,
Kusankha zinthu nthawi zambiri kumafuna kuunikanso kupitirira kuuma kokha.
