TPU firimuTPU, inozivikanwawo se polyurethane. Naizvozvo,TPU firimuinozivikanwawo sefirimu repolyurethane kana firimu repolyether, inova block polymer. TPU firimu rinosanganisira TPU yakagadzirwa nepolyether kana polyester (soft chain segment) kana polycaprolactone, isina-cross-linking.
Iri rudzi rwefirimu rine zvinhu zvakanakisa zvakadai sekupfava, kupfeka kuramba, uye makemikari kuramba, uye rinoshandiswa zvakanyanya munzvimbo dzakasiyana siyana. Muindasitiri yekurongedza, TPU firimu rinowanzo shandiswa mukurongedza chikafu kuchengetedza chikafu kubva mukusvibiswa kwekunze; Mundima yekurapa, inogona zvakare kushandiswa kurongedza zvigadzirwa zvekurapa kuve nechokwadi chehutsanana hwechigadzirwa uye kuchengetedzeka. Muchidimbu, hunhu hweTPU firimu hunoita kuti ive chinhu chakakosha mumaindasitiri mazhinji.
1. Yakanakisa kupfeka kuramba: Kupfeka kukosha kweTPU firimuiri 0.35-0.5mg, inova purasitiki diki. Kuwedzera lubricant kunogona kuderedza kupokana uye kuwedzera kunatsiridza kupfeka kuramba;
2. Kusimba kwesimba uye kusimba kwesimba: Kusimba kwesimba reTPU firimu ndeye 2-3 nguva yerabha rakachena rakasikwa uye rekugadzira rabha. Kusimba kwekusimba kwepolyester TPU yakakura kudarika yepolyurethane TPU, iyo ine simba rekusimba re60Mpa, kureba kwe410%, uye elongation ye550%.
3. Kuramba kwemafuta: TPU firimu ine mafuta ari nani kuramba kupfuura nitrile rubber uye ine mafuta akanaka ekudzivirira;
4. TPU firimu rine kutonhora kwakasimba, kuramba mamiriro ekunze, uye ozone kuramba kupfuura pure natural rabha uye mamwe ekugadzira rabha. Mabhenefiti ayo ekupokana neozone uye neradiation kuramba ane akasiyana makuru mashandisirwo muindasitiri yekubhururuka.
5. Chikafu uye giredhi rekurapa: TPU firimu ine biocompatibility uye anticoagulant basa, uye iri kuwedzera kushandiswa mune zvekurapa TPU mafirimu. Zvakadai setsinga dzeropa, droppers, uye liquid delivery tubes. TPU firimu harina anosimbisa maajenti, harina hwema kana chepfu, uye rinonyanya kushandiswa mumaindasitiri ezvekudya akasiyana;
6. Kuoma kwekushandiswa kwemhando: Kuoma kwefirimu yeTPU ndeye 60A-75D.TPU firimuine yakakwirira mutoro wekutsigira basa uye yakanakisa kusveta uye kuburitsa basa, saka ichine ductility kana kuoma kwakapfuura 85A, iyo isingawanikwe mune mamwe elastomers.
7. Kazhinji, TPU mafirimu akakamurwa polyester TPU mafirimu, polyether TPU mafirimu, uye polyethylene.TPU mafirimu.
TPU firimu harisi chete zvinhu zvinopokana nekudzvinyirirwa kwakanyanya uye kuchembera, asiwo zvinhu zvine hushamwari zvakatipoteredza izvo zvakanyatsokodzera kune zvemazuva ano zvinodiwa nevatengi. Inogona kushandiswa kushongedza manyatera eshangu, kumusoro, midziyo yekusimba, zvigaro zvemotokari, maamburera, mabhegi, mabhegi emhepo, macushion emhepo, uye mamwe mhando.
