TPU firimu, seyepamusoro-inoshanda polymer zvinhu, inoita basa rakakosha muminda yakawanda nekuda kwekusiyana kwayo kwemuviri uye makemikari zvimiro. Ichi chinyorwa chichadaro
nyura muzvinyorwa zvekugadzira, maitiro ekugadzira, maitiro, uye mashandisirwo eTPU firimu, kukutora iwe parwendo kuti utende kunaka kwetekinoroji yechinhu ichi.
1. Kugadzira zvinhu zveTPU firimu:
TPU firimu, rinozivikanwawo se thermoplastic polyurethane firimu, ifirimu rakatetepa rakagadzirwa nepolyurethane seyo substrate kuburikidza nehunyanzvi hwekugadzirisa. Polyurethane is a
polymer inogadzirwa nekuita kwe polyols uye isocyanates, ine yakanakisa kupfeka kuramba, elasticity, uye makemikari kuramba. Kuti ivandudze kushanda kwayo,
zvinoshanda zvekuwedzera senge antioxidants uye UV zvinotora zvinowedzerwawo panguva yekugadzirwa kweTPU mafirimu.
2. Maitiro ekugadzira:
Nzira yekugadzira yeTPU firimuyakanaka uye yakaoma, kunyanya kusanganisira matanho anotevera:
Aggregation reaction: Chekutanga, pasi pechiito checatalyst, polyols uye isocyanates inopinda polymerization reaction kuti igadzire polyurethane prepolymers.
Melt extrusion: Pisa iyo prepolymer kune yakanyunguduka wobva waiburitsa mufirimu kuburikidza nemusoro weextruder.
Kutonhodza uye kuumbwa: Iyo firimu yakanyungudutswa yakanyungudutswa inokurumidza kutonhodzwa neinotonhodza roller kuti iome uye iite.
Kugadziriswa kwekutumira: kunosanganisira kucheka, kupeta uye mamwe matanho, kuti pakupedzisira uwane iyo yapera TPU firimu.
3. Hunhu:
Hunhu hweTPU firimu ndiyo hwaro hwekushandisa kwayo kwakafara, inonyanya kuratidzwa mune zvinotevera zvinhu:
Simba repamusoro uye elasticity: TPU firimu rine yakakwira tensile simba uye yakanaka elastic kudzoreredza kugona, uye inogona kumirisana nemasimba makuru ekunze pasina deformation.
Pfeka kuramba: Kuoma kwepamusoro kuri pakati nepakati, nekunaka kupfeka kuramba, kwakakodzera kwakasiyana kwakaoma nharaunda.
Temperature kuramba: inokwanisa kuchengetedza kugadzikana mukati metembiricha ye -40 ℃ kusvika 120 ℃.
Kemikari inopikisa: Inopikisa zvakanaka kumakemikari mazhinji uye haisi nyore kuita ngura.
Moisture permeability: Iine imwe nhanho yekunyorova kwemvura uye inogona kuiswa mumamiriro ezvinhu apo kufema kunodiwa.
4, Application
Nekuda kwekuita kwayo kwakanaka, TPU firimu rave richishandiswa zvakanyanya munzvimbo dzakasiyana siyana, kusanganisira asi kwete kugumira ku:
Indasitiri yembatya: Semucheka wembatya, inopa jira rekudzivirira rakareruka, risina mvura, uye rinofema.
Munda wezvokurapa: Zvinhu zvekunze zvakaita senguwo dzekuvhiya, zvipfeko zvekudzivirira, nezvimwe zvinoshandiswa kugadzira michina yekurapa.
Midziyo yemitambo: inoshandiswa kugadzira shangu dzemitambo, mabhegi, uye zvimwe zvigadzirwa zvemitambo, zvinopa kusimba uye kunyaradza.
Indasitiri yemotokari: Seyemukati yekushongedza zvinhu, inogona kuvandudza kunyaradza uye aesthetics yenzvimbo yemotokari.
Munda wekuvaka: unoshandiswa kugadzira zvinhu zvedenga, matenga asingapindi mvura, nezvimwewo, kuvandudza kudzivirira kwemamiriro ekunze uye kushanda nesimba kwezvivakwa.
Kupfupisa, seyakawanda-inoshanda zvinhu, TPU firimu rave richinyanya kushandiswa zvakanyanya munharaunda yemazuva ano. Zvigadzirwa zvayo zvekugadzira zvakasiyana, maitiro ekugadzira
ari kufambira mberi, uye maitiro echigadzirwa akasiyana. Firimu reTPU, rine mabhenefiti aro akasiyana, rakaratidza kukosha kusingadzoreki muhupenyu hwemazuva ese uye minda yepamusoro-soro.
