TPE ndi zinthu zotani? Kodi matayala agalimoto a TPE amawononga thupi la munthu? Kuphatikiza ngati zinthu za TPE ndizowopsa?
Ili ndilo funso la ogula ambiri pakali pano. Monga zinthu zomwe zimagwirizana kwambiri ndi anthu, chitetezo chake cha chilengedwe komanso zinthu zopanda poizoni zimakhudzidwa mwachilengedwe ndi chidwi cha anthu. Mwachidule, TPE ndi pulasitiki ya elastomeric yokhala ndi mphira ndi zinthu za PVC.
M'moyo watsiku ndi tsiku, zinthu wamba zopangidwa ndi zida za TPE zimaphatikizapo zogwirira ntchito, zida zodumphira m'madzi, zida zamasewera, zoponya, matayala oundana, zoseweretsa zidole, zida zonyamula katundu, mawaya ndi zingwe, zinthu zazikulu, zida zamagalimoto, zolembera, mafilimu oteteza chilengedwe, ndi Pulasitiki yotanuka. mankhwala monga mapaipi ndi zisindikizo. Kenako, ndimayang'ana kwambiri kufotokoza za TPE ndi zomwe zili zovulaza thupi:
Choyamba, TPE ndi zinthu ziti?
TPE, yomwe imatchedwanso thermoplastic elastomer, ndi chinthu chokhala ndi mphamvu zambiri, mphamvu zambiri, mphira wolimba kwambiri, komanso mawonekedwe a jekeseni. Ndiwochezeka zachilengedwe, si poizoni ndi otetezeka, ali osiyanasiyana kuuma, ali colorability kwambiri, kukhudza zofewa, kukana nyengo, kukana kutopa ndi kutentha kukana, wapamwamba processing ntchito, palibe chifukwa vulcanization, ndipo akhoza recycled kuchepetsa ndalama. . Itha kukhala jekeseni wamitundu iwiri. Itha kukhala yokutidwa ndi kumangidwa ndi PP, PE, PC, PS, ABS ndi zipangizo zina zoyambira, kapena ikhoza kupangidwa mosiyana.
Chachiwiri, kodi zinthu za TPE ndizovulaza thupi?
TPE ndi zinthu zosawononga zachilengedwe, zopanda poizoni zomwe sizipanga mahomoni achilengedwe. Kuphatikiza apo, TPE ili ndi anti-skid komanso zoletsa kuvala. Imapangidwa ndi pulasitiki yolimba ndipo imakhala yomatira bwino ndi zinthu zazikulu za polypropylene. Zida ziwirizi ndi zofewa komanso zovuta kuphatikiza, ndi mitundu iwiri yofanana. PP imapereka mphamvu ya bolodi yodula, ndipo TPE imapereka katundu wotsutsa-skid wa bolodi locheka. , Pamene akuwonjezera kukongola kwa mankhwala. Poyerekeza ndi mapulasitiki wamba, kapangidwe ka TPU kokhala ndi mphamvu 3-4 sikungabweretse fungo lachilendo. Zida za TPE zili ndi izi:
1.Kumverera kwamanja kwapamwamba: mphamvu zambiri; kupirira kwakukulu; kusinthasintha kwakukulu; wosakhwima ndi wosalala; phulusa losamamatira.
2.Kuchita bwino kwambiri: kukana kwa UV; kukana kukalamba; asidi ndi alkali kukana; kukana kutopa.
3.Easy pokonza: zabwino fluidity; mphamvu yokoka yowala; zosavuta kukongoletsa. Oyenera jekeseni akamaumba; extrusion akamaumba.
4.Chitetezo chobiriwira ndi chilengedwe: kukumana ndi FDA (n-hexane); Miyezo yoyesera ya LFGB (mafuta a azitona).
5.Kuumba ndondomeko: choyamba kuyeretsa makina ndi PP (polypropylene); kutentha akamaumba ndi 180-210 ℃.
6.Ntchito minda: ana mankhwala; mankhwala mankhwala; tableware; zofunika tsiku ndi tsiku; khitchini ndi bafa katundu; kuteteza chilengedwe.
7. Zogulitsa zomwe zimafunikira chakudya chamagulu.
Chifukwa chake, zinthu za TPE sizowopsa komanso zokondera zachilengedwe, ndipo zimakumana ndi satifiketi ya ROHS yoteteza zachilengedwe. Chonde khalani omasuka kugwiritsa ntchito.
