Kodi pali kusiyana kotani pakati pa magolovesi a CPE, magolovesi a TPE ndi magolovesi a TPU?

1. Mbali

Magolovesi a TPE ali ndi makhalidwe okana kukalamba, kusungunuka kwakukulu ndi kukana mafuta, ndipo ndi osavuta kukonza ndi kupanga;Magolovesi a CPE ali ndi mawonekedwe a mtengo wotsika, kufewa komanso kugwiritsa ntchito zosiyanasiyana.

2. Chitetezo

Magolovesi a CPE amatha kuwola mosavuta mpweya wa hydrogen chloride pa 50 ℃, womwe ndi wovulaza thupi la munthu.Ntchito yopanga ndi kukonza idzawononga chilengedwe, ndipo chitetezo ndi chochepa;Magolovesi a TPE ndi mtundu wazinthu zoteteza chilengedwe, zomwe zimatha kubwezeredwa ndikugwiritsidwanso ntchito.Sichidzatulutsa poizoni pansi pa kutentha kwakukulu, ndipo ndizotetezeka kuti anthu azigwiritsa ntchito.
Kusiyana pakati pa TPE, CPE ndi TPU:
Zida zazikulu zamagolovu a CPE ndi LDPE, LLDPE, mLLDPE, etc.
Tpe-thermoplastic elastomer ndi chinthu chatsopano chokhala ndi elasticity kwambiri, mphamvu yayikulu komanso kulimba kwambiri kwa mphira.
TPU ndi thermoplastic polyurethane elastomer, yomwe imatha kugawidwa mu TPE thermoplastic elastomer.
Kulimba mtima ndi kukana kwa TPU kuli bwino kuposa kwa TPE, komwe kumachitika makamaka chifukwa cha kusiyana kwa magawo a maselo.Kuphatikiza apo, ma microstructure ndi katundu wa TPE blends ndi otsika poyerekeza ndi a TPU.Magawo ambiri a TPE adzakhala ndi zotsatira zoyipa pamachitidwe ake a springback.Makamaka TPE yokhala ndi kuuma kwakukulu, gawo lalikulu la gawo la polypropylene limapangitsa kuti kulimba kwa TPE kuchepe kwambiri, ndipo zinthuzo zimatha kupindika pansi pakuchita mosalekeza kwa mphamvu yakunja.
Kumverera m'manja: TPU ili ndi kukana kovala kwambiri, kukangana kwamphamvu m'manja komanso kusalala bwino.
TPE: chifukwa cha mawonekedwe osinthika a ma cell a SEBS, zinthuzo zimamveka zofewa, zofewa komanso zosalala
Malingaliro a CPE ndi ofanana kwambiri ndi a TPE.Kanema wa CPE wopangidwa ndi embossing roller ali ndi mawonekedwe abwino komanso okhuthala.

Mawonekedwe:Magolovesi a TPE ali ndi makhalidwe okana kukalamba, kusungunuka kwakukulu ndi kukana mafuta, ndipo ndi osavuta kukonza ndi kupanga;

Zinthu za TPE zili ndi kukhudza kofewa, kukana nyengo yabwino komanso palibe plasticizer.Ndizinthu zachilengedwe komanso zopanda poizoni zomwe zimakhala ndi mtengo wa 20000-50000 / ton.Amagwiritsidwa ntchito kwambiri pazofunikira za tsiku ndi tsiku pokhudzana ndi thupi la munthu.Chifukwa zinyalala za TPE zitha kusinthidwanso 100%, kupulumutsa mtengo, kupanga ndi kukonza bwino, ndipo palibe vulcanization yomwe imafunikira, imatha kukonzedwa ndi makina opangira thermoplastic.The processing njira monga jekeseni akamaumba, extrusion, kuwomba akamaumba, calendering, etc.

Magolovesi a CPE ndi otsika mtengo, ofewa komanso amagwiritsidwa ntchito kwambiri
