Zvimiro zveTPU Firimu Zvisingapindi Mvura uye Zvinopinda Mumvura

Basa guru reFirimu reThermoplastic Polyurethane (TPU)Iri munzvimbo yayo isingapindi mvura uye inokwanisa kupinda mumvura—inogona kudzivirira mvura kuti isapinde uku ichibvumira mamorekuru emvura (dikita, ziya) kuti apfuure nepakati.

1. Zviratidzo zveKushanda uye Maitiro

1. Kusapinda Mvura (Kusadyidzana Nekumanikidzwa Kwemvura):
   • Chiratidzo: Chinoyera kugona kwefirimu kurwisa kumanikidzwa kwemvura kwekunze, kunoyerwa mu kilopascals (kPa) kana mamilimita ekoramu yemvura (mmH₂O). Kukosha kwepamusoro kunoratidza kushanda kwakasimba kwemvura isingapindi mvura. Semuenzaniso, mbatya dzekunze dzenguva dzose dzingada ≥13 kPa, nepo michina yemhando yepamusoro ingada ≥50 kPa.
   • Standard Test: Inowanzo edzwa uchishandisa ISO 811 kana ASTM D751 (Burst Strength Method). Izvi zvinosanganisira kuramba uchiwedzera kumanikidzwa kwemvura kune rumwe rutivi rwefirimu kusvika madonhwe emvura aonekwa kune rumwe rutivi, zvichinyora kukosha kwekumanikidzwa panguva iyoyo.
2. Kupinda kwehunyoro (Kutapurirana kweUtsi):
   • Chiratidzo: Chinoyera huwandu hwemvura inopfuura nepakati pechikamu chefirimu panguva imwe neimwe, inoonekwa mumagiramu pa square meter pamaawa makumi maviri nemana (g/m²/24h). Kukosha kwepamusoro kunoratidza kufema kuri nani uye kubuda kwedikita. Kazhinji, kukosha kunodarika 5000 g/m²/24h kunoonekwa sekunge kunofema zvakanyanya.
   • Standard Test: Nzira mbiri huru dziripo:
     • Nzira yeKuisa Kapu Yakamira (Nzira yeKuisa Kapu): semuenzaniso, ASTM E96 BW. Desiccant inoiswa mukapu, yovharwa nefirimu, uye huwandu hwemvura inonyudzwa pasi pemamiriro ekupisa nehunyoro hwakatarwa hunoyerwa. Mhedzisiro yacho iri pedyo nemamiriro chaiwo ekupfekwa.
     • Nzira yeKapu Yakapindurwa (Nzira yeMvura): semuenzaniso, ISO 15496. Mvura inoiswa mukapu, iyo inopindurwa yovharwa nefirimu, uye huwandu hwemvura inobuda mufirimu hunoyerwa. Nzira iyi inokurumidza uye inowanzoshandiswa kudzora mhando.

2. Nheyo yekushanda

Hunhu husingapindi mvura uye hunogona kupinda hunyoro hweFirimu reTPUHazviwanikwe kuburikidza nemaburi emuviri asi zvinoenderana nekushanda kwezvikamu zvemaketani ayo anofema mvura:

• Haipindi mvura: Firimu racho rakakora uye harina maburi; mvura yemvura haigone kupfuura nepakati nekuda kwekumanikidzwa kwaro pamusoro uye chimiro chemamorekuru efirimu racho.
• Hunyoro Hunopindika: Iyo polymer ine mapoka anonyungudika mumvura (semuenzaniso, -NHCOO-). Mapoka aya "anobata" mamorekuru emvura anobuda kubva paganda riri mukati. Zvadaro, kuburikidza ne "kufamba kwezvikamu" zvemaketani epolymer, mamorekuru emvura "anotapurirwa" nhanho nhanho kubva mukati kuenda kunharaunda yekunze.

3. Nzira dzeKuedza

1. Hydrostatic Pressure Tester: Inoshandiswa kuyera nemazvo kumanikidzwa kwemuganho wemvura wefirimu kana jira.
2. Kapu yeKugara Nehunyoro: Inoshandiswa mukati mekamuri rinogara richipisa uye rine hunyoro kuyera mwero wekufambiswa kwehunyoro (MVTR) uchishandisa nzira yekapu yakamira kana yakapindurwa.

4. Mashandisirwo

Kushandisa zvinhu izvi,Firimu reTPUndiyo sarudzo inosarudzwa kune akawanda maapplication epamusoro-soro:

• Zvipfeko zvekunze: Chinhu chakakosha mujaketi dzakasimba, zvipfeko zveski, uye mabhurugwa ekufamba netsoka, zvichiita kuti vanofarira zvekunze vaome uye vanyarare kana mhepo nemvura ichinaya.
• Dziviriro Yekurapa: Inoshandiswa mumagown ekuvhiya uye zvipfeko zvekudzivirira kudzivirira ropa nemvura yemuviri (inodzivirira mvura) ukuwo ichibvumira ziya rinogadzirwa nevashandi vekurapa kubuda, zvichideredza kupisa.
• Kudzimura moto uye Kudzidziswa kwemauto: Kunopa dziviriro munzvimbo dzakaoma, zvinoda kuramba moto, mvura, uye makemikari, pamwe chete nekukwanisa kufema zvakanyanya kuchengetedza kufamba uye kushanda zvakanaka.
• Zvishandiso zveShangu: Zvinoshandiswa semabhutsu asingapindi mvura (booties) kuchengetedza tsoka dzakaoma kana kuchinaya uku zvichidzivirira kupisa kwemukati uye hunyoro.

Muchidimbu, kuburikidza nemagadzirirwo ayo akasiyana emuviri nemakemikari, firimu reTPU rinoenzanisa neunyanzvi zvinodiwa zvinoita sekunge zvinopesana zvekuti "hazvipindi mvura" uye "zvinofema," zvichiita kuti rive chinhu chakakosha mumunda wemachira anoshanda zvakanyanya.
