1. Makhalidwe a TPEgulu lotsutsa
Zinthu za TPE zimakhala ndi mphamvu zolimba komanso zolimba, ndipo zimamveka bwino komanso zosalala.Imatulutsidwa mwachindunji ndikupangidwa ndi extruder, ndipo kukonza kwake ndikosavuta komanso kosavuta.TPE ili ndi kukana kwamafuta ochepa.TPE imayaka ndi fungo lochepa, ndipo utsi ndi wochepa komanso wopepuka.
Zinthu za TPE ndi zinthu zosinthidwa zosakanikirana, ndipo mawonekedwe ake amakhala ndi zosinthika zambiri, ndipo mphamvu yokoka ili pakati pa 0.89 ndi 1.3.Kuuma nthawi zambiri kumakhala pakati pa 28A-35A Shore.Kuuma kwambiri kapena kutsika kwambiri kumakhudza magwiridwe antchito agulu lotsutsa.
Mtengo TPEgulu lotsutsa zinthu zimagwiritsa ntchito SEBS ngati chinthu chachikulu.SEBS ndizinthu zokonda zachilengedwe zomwe zimakwaniritsa mulingo wa REACH, chifukwa chake sizingabweretse matupi awo kumagulu apadera.Lamba wotanuka wopangidwa ndi TPE umakhala wosalala, wopanda tinthu tating'onoting'ono ndi zinthu zakunja, ndipo umasungabe kukhazikika bwino m'malo otentha otsika popanda kukhala olimba komanso olimba.Kukana kwanyengo kwabwino, kumatha kugwiritsidwa ntchito m'malo a 40-90 digiri Celsius, ndipo sipadzakhala kusweka kwa ntchito yakunja mkati mwa kutentha uku.
Zinthu zazikulu zomwe zimagwiritsidwa ntchito mu TPE, SEBS, zimakhala ndi butadiene yambiri, yomwe imakhala ndi mawonekedwe otambasula kwambiri komanso mapindikidwe ang'onoang'ono.Tidayesa kuti kutambasula katatu kwanthawi zopitilira 30,000 kungayambitse kupindika pang'ono, koma osapitilira 5%.

Latex ili ndi kukana kovala bwino, kukana kutentha, kutsika kwambiri, kung'ambika komanso kutalika kopitilira nthawi 7.N'zosavuta kukalamba mu mlengalenga, whitening pamene kupopera mbewu mankhwalawa chisanu.Chifukwa cha kukhalapo kwa mamolekyu amtundu wa mapuloteni mu latex yachilengedwe, zimatha kuyambitsa ziwengo mwa anthu ena.
Natural latex imadulidwa kuchokera kumtengo wa rabara.Ndi mtundu wa mphira wachilengedwe.Ndi yamadzimadzi, yoyera ngati yamkaka, komanso yopanda kukoma.Mwatsopano latex wachilengedwe uli ndi 27% mpaka 41.3% ya mphira, 44% mpaka 70% yamadzi, 0.2% mpaka 4.5% ya mapuloteni, 2% mpaka 5% ya utomoni wachilengedwe, 0.36% mpaka 4.2% ya shuga, ndi 0.4% ya phulusa.Pofuna kupewa latex yachilengedwe kuti isagwirizane chifukwa cha ma microorganisms ake ndi ma enzymes, ammonia ndi ma stabilizer ena amawonjezeredwa nthawi zambiri.
Resistance band latex ndi yabwino kapena tpe ndiyabwino, zonse zili ndi zabwino ndi zoyipa.Ntchito m'munda wagulu lotsutsas, kusankha kwa zinthu za TPE ndikokwanira kugwiritsa ntchito ntchito yake, ndipo mtengo wake ndi wotsika mtengo.Poyerekeza zida ziwirizi, palibe zabwino kapena zoyipa.Timafunikirabe kusankha molingana ndi magwiridwe antchito ndi zofunikira pakugwiritsa ntchito.
2. Kusiyana pakati pa TPUgulu lotsutsa ndi TPEgulu lotsutsa
Ngakhale TPU ndi TPE ndi zilembo zosiyana, kugwiritsa ntchito TPUgulu lotsutsa ndi TPEgulu lotsutsa ndi zosiyana kwambiri.Mtengo wapatali wa magawo TPUgulu lotsutsa amawala m'munda wa zida zoluka zobvala, monga kolala ndi ma cuffs a zovala zoluka, msoko wa mapewa ndi mbali zam'mbali.Zomwe TPE elasticity imatenga ndikuti njira yamphamvu imakhala ndi zida zolimbitsa thupi, monga kulimbagulu lotsutsas, zida zolimbitsa thupi zolimbitsa thupi ndi zina zotero.Kaya ndi TPUgulu lotsutsa kapena TPEgulu lotsutsa, ndi ochezeka ndi chilengedwe komanso okhalitsa.Kusiyana kwakukulu pakati pawo ndi kusiyana kwa mawonekedwe m'lifupi ndi makulidwe ndi kukula kwa ntchito.Zoonadi, zopangira ndizosiyana pang'ono.
1. Kusiyana kwa maonekedwe ndi kukula kwa ntchito
Mtengo wa TPUgulu lotsutsa imakhala yowoneka bwino kwambiri, nthawi zambiri m'lifupi mwake ndi pakati pa 2MM ndi 30MM, ndipo makulidwe ake ndi pakati pa 0.08MM ndi 1MM.Amagwiritsidwa ntchito pa kolala ndi ma cuffs a zovala zoluka, ndipo mapewa am'mphepete mwa mapewa amapangidwa kuti apereke zotsatira zabwino zosaoneka.Palibe chifukwa choganizira mtundu wofananira;m'lifupi mwake nthawi zambiri amafanana ndi m'lifupi mwake, zomwe zimapangitsa kuti zikhale zosavuta kubisa lamba;makulidwe owonda kwambiri sangakhudze chitonthozo cha zovala zoluka pambuyo pa kusoka.
Mtengo wa TPEgulu lotsutsa ndi zosiyanasiyana, monga zachilengedwe mtundu, buluu, chikasu, zobiriwira, wofiira, lalanje, pinki, wofiirira, etc. M'lifupi ambiri ndi 75-150mm, ndi makulidwe ndi 0.35mm, 0.45mm, 0.55mm, 0.65mm, etc. ., Mitunduyi ndi yosiyanasiyana komanso yosavuta kuti ogwiritsa ntchito asankhe.Chifukwa TPEgulu lotsutsa ndi yotakata komanso yokulirapo, imatha kupirira kupsinjika bwino ndipo ndiyoyenera kugwiritsidwa ntchito pazida zolimbitsa thupi.
2. Kusiyana pakati pa zipangizo
Onse TPU ndi TPE ndi zipangizo thermoplastic ndi mphira elasticity, ndipo onse ali ndi mphira elasticity wabwino.Poyerekeza, TPE ndiyabwino kwambiri ponena za chitonthozo cha tactile, ndipo TPU ili ndi kukhuthala kwambiri komanso mphamvu.Ndizovuta kusiyanitsa pakati pa TPE ndi TPU pongoyang'ana pawokha.Yambani ndi tsatanetsatane kuti muwunike kusiyana ndi kusiyana pakati pa TPE ndi TPU:
1) Kuwonekera kwa TPU kuli bwino kuposa TPE, ndipo sikophweka kumamatira ngati TPE yowonekera;
2) Mphamvu yokoka ya TPU imasiyana mosiyanasiyana, kuyambira 1.0 mpaka 1.4, pamene TPE ili pakati pa 0.89 mpaka 1.3, makamaka mwa mawonekedwe osakanikirana, kotero mphamvu yokoka imasintha kwambiri;
3) TPU ili ndi kukana bwino kwamafuta, pomwe TPE ili ndi kukana kwamafuta ochepa;
4) TPU imayaka ndi fungo lopepuka, lokhala ndi utsi wochepa komanso wopepuka, ndipo pali phokoso laling'ono lophulika pamene likuyaka, TPE imakhala ndi fungo lowala pamene ikuyaka, ndipo utsi ndi wochepa komanso wopepuka;
5) TPU a elasticity ndi zotanuka kuchira ntchito bwino kuposa TPE;
6) TPU kutentha kukana ndi -60 madigiri Celsius mpaka 80 madigiri Celsius, TPE ndi -60 madigiri Celsius mpaka 105 madigiri Celsius;
7) Pankhani ya maonekedwe ndi kumverera, pazinthu zina zowonongeka, zinthu za TPU zimakhala ndi zomveka bwino komanso zotsutsana kwambiri kuposa mankhwala a TPE;pomwe zinthu za TPE zimakhala ndi zofewa komanso zofewa komanso zomangika pang'ono.
Kawirikawiri, TPUgulu lotsutsa ndi yowonekera komanso yachisanu, yopepuka komanso yofewa, imakhala yolimba bwino, yolimba bwino, ndipo sivuta kuthyoka.Ndi yoyenera knitwear kolala cuff hemming ndi mapewa msoko mbali msoko.Mtengo TPEgulu lotsutsa ali ndi mitundu yosiyanasiyana, omasuka kukhudza, ali ndi mphamvu yotambasula kwambiri, ndipo amatha kupirira kwambiri.Ndizoyenera kugwiritsidwa ntchito pazida zolimbitsa thupi.
