Solvent-Based TPU sekhomaretsi se setle sa viscosity
ka TPU
TPU (thermoplastic polyurethanes) e koala lekhalo la thepa lipakeng tsa liraba le polasetiki.Mefuta e mengata ea thepa ea 'mele e nolofalletsa TPU hore e sebelisoe e le rabara e thata le thermoplastic.TPU e bonolo ea boenjiniere e fihletse tšebeliso e pharaletseng le botumo ba lihlahisoa tse likete, ka lebaka la ho tšoarella ha tsona, bonolo le mebala har'a melemo e meng.Ho phaella moo, li bonolo ho sebetsa.
E le thepa e hlahang ea theknoloji e phahameng le e lumellanang le tikoloho, TPU e na le thepa e mengata e babatsehang joaloka mefuta e mengata e thata, matla a phahameng a mochine, ho hanyetsa serame se tsotehang, ts'ebetso e ntle ea ts'ebetso, ho senyeha ha tikoloho, ho hanyetsa oli, ho hanyetsa metsi le ho hanyetsa hlobo.
Kopo
Lisebelisoa: Likhomaretsi tsa Solvent, Lifilimi tse Khomarelang tse chesang tse chesang, Sekhomaretsi sa Lieta.
