Zvinhu Zvikuru uye Kuongorora Kunoshanda kweInflatable Fabric Material Selection
Seyakakosha nzvimbo yekushandisa yeazvino zvigadzirwa sainzi, machira anofembera anokanganisa zvakananga kuita kwechigadzirwa uye hupenyu hwehupenyu. Machira e inflatable anoshandiswa zvakanyanya mumidziyo yekunze, midziyo yekubatsira yekurapa, uye zvekuvaraidza uye zvigadzirwa zvevaraidzo nekuda kwekureruka kwavo, kutakurika, uye kushanda. Ichi chinyorwa chinoongorora zvine hungwaru nzira dzekusarudza zvinhu zvemachira anofema kubva pamaonero matatu: zvinhu zvemukati, zvinoshanda zvinodiwa, uye kuchinjika kwezvakatipoteredza.
Kubva pakuona kwekutanga kwezvinhu, machira emazuva ano anofembera anonyanya kushandisa mapolymer seyawo yepakati raw material. Machira epolurethane (PU)-akavharidzirwa, nokuda kwekunaka kwawo elastic modulus uye abrasion resistance, ava iwo emhando yezvigadzirwa zvepakati- kusvika kumusoro{3}}zvinogadzirwa. Ichi chinyorwa chinochengetedza mhepo yakanakisa uku ichishingirira kushushikana kwemakanika kwekudzokorora inflation uye deflation. Kana tichienzanisa, firimu repolyethylene (PE), kunyange risingadhure, rinotambura nekusasimba kwekuita ductility uye kusakwana kwekupinza kwekupinza, zvichiita kuti risakodzere maapplication anoda kushandiswa kwenguva refu-. Zvinoshamisa, kubuda kwezvinhu zvitsva zve thermoplastic polyurethane (TPU) zvakavandudza zvakanyanya kuramba kwavo kwemamiriro ekunze uye kuita kwezvakatipoteredza kuburikidza nekugadzirisa mamorekuru, nekudzikira kunenge 40% kupfupi pane izvo zvechinyakare zvePU zvinhu.
Basa-kusarudzwa kwezvinhu zvakanangana kunofanirwa kukoshesa zvinodikanwa zvechinodiwa chekushandisa. Mumunda wekununura kunze, midziyo yakaita se inflatable stretchers inoda machira ane simba uye anofema. Zviviri-zvimiro zvakaumbwa mhinduro inoshanda: 210D jira renaironi rekunze rinowedzera kusada kubvarura, nepo microporous PU firimu rinoshandiswa mukati memukati kufambisa kuchinjana kwegasi. Pamidziyo yemitambo yemumvura, yakaita semabhachi ehupenyu anofembera, kusarudza zvinhu kunofanirwa kuisa pamberi pakati pekunaka uye kunzwa kweganda. Kazhinji, furo rakavharwa-sero EVA rine density ye0.91 g/cm³ rakanamirwa nePVC{10}}jira rakavharidzirwa. Izvi zvinoita kuti vhoriyamu iwedzere 0.024 m³ uku ichiwedzera kunyaradza kuburikidza nekugadzirwa kwepamusoro. Medical matiresi emhepo anoisa zvakatonyanya kudiwa pane zvinhu biocompatibility. Machira -giredhi silikoni{16}}akaiswa machira, nekuda kwe-asina allergenic uye asingaurayiwi, atova emazuva ose muzvipatara.
Kuchinjika kwezvakatipoteredza chinhu chakakosha tekinoroji parameter mukusarudza zvinhu. Masikirini ezuva ane Ultraviolet Protection Factor (UPF) ye 50+ anogona kunonotsa kuchembera munzvimbo -yakakwirira yezuva. Pakudzika kwe polar-tembiricha yekushanda, yakagadziridzwa rubber matrix yakaiswa ne boron carbide nanoparticles inogona kuderedza tembiricha yayo kusvika pasi pe -40 madhigirii , zvichiita kuti igone kusanduka mumamiriro ekutonhora kwakanyanya. Munzvimbo dzemugungwa, machira akaumbwa akavharwa nekudzivirira katatu (anti-mildew, anti-salt spray, uye anti-algae) anogona kuwana makona ekusangana kwepamusoro anodarika 115 degrees, zvichideredza zvakanyanya mwero wekukukurwa kwemvura yegungwa. Data yerabhoritari inoratidza kuti mushure memaawa 500 ekunyudzwa pasi pemvura, gasi rekubuda kwemachira akarapwa nano-hydrophobic rinoramba riri mukati me3% yemutengo wekutanga.
Material innovation iri kutyaira inoenderera mberi mune inflatable jira tekinoroji. Tsvagiridzo nekuvandudza bio{{1}based polyurethanes yawana budiriro yekutanga. Chizvarwa chitsva chemidziyo yakagadzirwa kubva kumafuta ezvirimwa chine 62% yakaderera kabhoni tsoka uku ichichengetedza inofananidzwa mechanical zvivakwa kune yechinyakare polyurethane. Kushandiswa kwemapolymers emuumbirwo kunopa kuzvirapa kumachira. Pakaonekwa kuti kune micro-kukuvadza kuri pasi pe 0.5 mm, machira anogona kugadzirwa nekubatanidza cheni dzemamolecular kuburikidza nekudziya kwenzvimbo. Kugadzirwa kwehungwaru pressure{10}}inogadzirisa machira inobatanidza shape memory alloy fiber network inogadzirisa kuvhura nekuvharika kwemhepo zvichienderana nekuchinja kwe ambient pressure. Iyi tekinoroji yakapinda muchikamu chekuyedza mumunda muindasitiri yemuchadenga.
Sarudzo yesainzi-mukusarudza zvinhu zvinoda hurongwa hwekuongorora. Ongororo yakazara inokurudzirwa pamatanho matatu: yekutanga midziyo yekuyedza (kusanganisira kusimba kwesimba Kukura kupfuura kana kuenzana ne200N/5cm uye kubvarura simba Kukura kupfuura kana kuenzana ne50N), mashandiro echokwadi (airtightness bvunzo: kuchengetedza kudzvanywa kweKupfuura kana kuenzana nemaawa makumi maviri nemana pasina kudonha kudonha), uye kukurumidza kuchembera kusvika kumakore matatu equivalent, maawa makumi manomwe neshanu. kuchembera). Pakutenga kwakawanda, diki-yeyedzo yekuchinjika kwezvakatipoteredza inofanirawo kuitwa, kusanganisira kuchovha tembiricha kubva -30 madhigirii kusvika 70 madhigirii uye kuyedza kusimba pa85% mwando.
Parizvino, kusarudzwa kwemachira anofembera kwachinja kubva kune imwe-maitiro ekuita kuenda kune yakawanda-madimensional performance balance. Nekufambira mberi mune zvesainzi, budiriro yeramangwana ichatarisa kukwenenzverwa kwehuremu uye simba repamusoro, hukuru-kushandiswa kwechikero chemidziyo inochengetedza zvakatipoteredza, uye dhizaini yakasanganiswa yemabasa akangwara ekupindura. Pakusarudza machira anofembera, vashandi vane hunyanzvi vanofanira kugadzira matatu-yakareba sarudzo-yekugadzira modhi inobatanidza zvinhu zvinobatika, mutengo-unyanzvi, uye mamiriro ezvakatipoteredza zvichienderana nezvinokosheswa nemamiriro ekushandisa, nokudaro vachiwana kuenzanisa pakati pemashandisirwo echigadzirwa noukoshi hunoshanda.
