Maemo a thata bakeng sa li-elastomer tsa TPU-thermoplastic polyurethane

Bothata baTPU (thermoplastic polyurethane elastomer)ke e 'ngoe ea litšobotsi tsa eona tsa bohlokoa tsa' mele, tse etsang qeto ea hore na thepa e khona ho hanela deformation, mengoapo le mengoapo. Ho thatafala hangata ho lekanyetsoa ho sebelisoa mochini o hlahlobang boima ba Shore, o arotsoeng ka mefuta e 'meli e fapaneng: Shore A le Shore D, e sebelisetsoang ho metha.Lisebelisoa tsa TPUka mefuta e fapaneng ea boima.

Ho ea ka liphetho tsa lipatlisiso, mefuta e thata ea TPU e ka tloha Shore 60A ho ea Shore 80D, e lumellang TPU ho pharalla le mefuta e thata ea rabara le polasetiki le ho boloka elasticity e phahameng ho pholletsa le mefuta eohle ea boima. Tokiso ea boima e ka finyelloa ka ho fetola karolo ea likarolo tse bonolo le tse thata ka har'a ketane ea limolek'hule tsa TPU. Phetoho ea boima ba 'mele e ka ama thepa e meng ea TPU, joalo ka ho eketsa boima ba TPU e lebisang keketsehong ea modulus e tsitsitseng le matla a tabohang, ho eketseha ha boima le khatello ea maikutlo, ho fokotseha ha bolelele, ho eketseha ha letsoalo le ho hlahisa mocheso o matla. , le keketseho ea khanyetso ea tikoloho.

Lits'ebetsong tse sebetsang, thekhetho ea boima ba TPUe tla khethoa ho latela litlhoko tse khethehileng tsa kopo. Mohlala, TPU e bonolo (e lekantsoeng ke Shore A hardness tester) e loketse lihlahisoa tse hlokang ho ts'oaroa ha bonolo le bolelele bo phahameng, athe TPU e thata (e lekantsoeng ke Shore D hardness tester) e loketse lihlahisoa tse hlokang matla a holimo a ho jara le a matle. apara khanyetso.

Ntle le moo, bahlahisi ba fapaneng ba kanna ba ba le maemo a thata a thata le litlhaloso tsa sehlahisoa, tseo hangata li hlalosoang ka botlalo libukeng tsa mahlale a sehlahisoa. Ho fumana lintlha, ka kopo sheba webosaete ea semmuso eaYantai Linghua New Materials Co., Ltd.

Ha u khetha thepa ea TPU, ntle le ho thatafala, lisebelisoa tse ling tsa 'mele, mekhoa ea ho sebetsa, ho ikamahanya le maemo a tikoloho, le lintlha tsa litšenyehelo li lokela ho nahanoa ho netefatsa hore lisebelisoa tse khethiloeng li ka finyella litlhoko tsa ts'ebetso ea likopo tse itseng.
