Mundima yakakura yesayenzi yezvinhu,TPU firimuiri kubuda zvishoma nezvishoma sekutarisa kwekutarisisa mumaindasitiri akawanda nekuda kwezvakasiyana zvivakwa uye yakakura mashandisirwo. TPU firimu, kureva thermoplastic polyurethane firimu, ifirimu rakatetepa rakagadzirwa kubva ku polyurethane raw materials kuburikidza nemaitiro akakosha. Chimiro chayo chemorekuru chine ese anochinjika zvikamu uye akaomesesa mativi, uye ichi chakasarudzika chimiro chinopa TPU firimu nenhevedzano yezvakanakisa zvivakwa, zvichiita kuti iratidze mabhenefiti asingaenzaniswi muminda yakawanda.

Kuita Kwakanakira kweTPU Firimu

Yakanakisa Mechanical Properties

Imwe yemabhenefiti akakosha eTPU firimu ndeye yakanakisa mekiniki zvivakwa, iyo inosanganisa yakakwirira simba uye yakakwirira elasticity. Simba rekusimba rinogona kusvika pa20-50MPa, uye mamwe mamodheru anotopfuura 60MPa. Iyo elongation panguva yekuzorora inogona kusvika 300% -1000%, uye elastic kupora rate inodarika 90%. Izvi zvinoreva kuti kunyangwe iyo TPU firimu yakatambanudzwa kakawanda kureba kwayo kwepakutanga, inogona kukurumidza kudzoka kuchimiro chayo chepakutanga mushure mekuburitswa, iine inenge isina deformation zvachose. Semuenzaniso, mukugadzirwa kweshangu dzemitambo, TPU firimu, sechinhu chepamusoro cheshangu, inogona kuchinjika kutambanudza nekufamba kwetsoka, ichipa yakagadzikana yekupfeka ruzivo uchichengetedza chimiro chakanaka uye kutsigirwa.

Iyi "musanganiswa wekusimba uye kuchinjika" kunobva kune synergistic mhedzisiro yezvikamu zvakaoma (isocyanate segments) uye zvinyoro zvikamu (polyol segments) mumaketani ayo mamorekuru. Iwo akaomeswa zvikamu zvinoumba emuviri muchinjikwa-kubatanidza mapoinzi, senge simbi mbariro muzvivakwa, kupa simba rutsigiro zvinhu; zvikamu zvinyoro, sezvitubu, zvinopa zvinhu ne elasticity. Chiyero chezviviri chinogona kunyatsogadziriswa kuburikidza nekugadzirisa fomula, kuitira kuti isangane nezvinodiwa zvakasiyana kubva ku "high elasticity pedyo nerabha" kusvika ku "simba guru rakafanana nemapurasitiki einjiniya".

Mukuwedzera, TPU firimu zvakare ine yakanakisa kubvarura kuramba uye kupfeka kuramba. Simba rekurudyi rinobvarura ≥40kN/m, uye kurasikirwa kwekupfeka kuri ≤5mg/1000 nguva, izvo zviri nani kupfuura zvigadzirwa zvemafirimu zvechinyakare sePVC nePE. Mumunda wemidziyo yekunze yemitambo, yakadai seyekutakura mabhegi ekukwira makomo uye kumucheto kwekudzivirira kwemabhodhi e ski, kuramba kwemisodzi yakakura uye kuramba kupfeka kweTPU firimu kunogona kunyatso kuwedzera hupenyu hwesevhisi yezvigadzirwa uye kushingirira kuyedzwa kwenzvimbo dzakaomarara.

Yakanakisa Environmental Resistance

TPU firimuinoita zvakanaka maererano nekupikisa kwezvakatipoteredza uye inogona kuenderana neakasiyana siyana akaoma mamiriro ezvakatipoteredza. Panyaya yekudzivirira kwekushisa, inogona kuchengetedza kushanda kwakadzikama muhupamhi hwekushisa kwe -40 ℃ kusvika 80 ℃. Munzvimbo dzakaderera-kupisa, zvikamu zvakapfava hazviite crystallize, kudzivisa brittle kuputsika kwezvinhu; munzvimbo dzakakwirira-kupisa, zvikamu zvakaoma hazvinyunguduki, kuchengetedza simba rekugadzirisa zvinhu. Hunhu uhwu hunoita kuti firimu reTPU rishandiswe munzvimbo dzinotonhora dzepolar, sekugadzira zvisingapinde mvura uye zvinofema masutu emasutu ekufambisa, uye zvakare kuita basa munzvimbo dzinopisa dzerenje, senge mafirimu ekudzivirira ekudzivirira kupisa mumakamuri einjini yemotokari.

Panguva imwecheteyo, TPU firimu ine yakasarudzika mamiriro ekunze. Mushure meawa 1000 ye ultraviolet kuchembera bvunzo, iyo attenuation mwero wekuita kwayo kusimba ndeye 10% -15% chete, iyo yakaderera zvakanyanya kupfuura iyo yePVC firimu (kupfuura 50%). Uyezve, haina hanya nekushanduka kwehunyoro, uye kana ichishandiswa munzvimbo ine hunyoro hunyoro hwe90% kwenguva yakareba, kushanduka kwekuita kunogona kudzorwa mukati me5%. Naizvozvo, TPU firimu rakanyatsokodzera zvekunze zvekuvaka zvinhu, senge sunshades uye kuvaka membrane zvimiro, izvo zvinogona kuramba kukukurwa kweultraviolet mwaranzi, mhepo, mvura uye hunyoro kwenguva yakareba uye kuchengetedza kuita kwakanaka uye kutaridzika.

Yakanaka Kemikari Kugadzikana uye Kushanda Kusiyanisa

TPU firimu rine kuramba kwakanaka kune zvakajairika midhiya senge mvura, mafuta, asidhi uye alkali. Mushure mekunyoroveswa mumvura kwemazuva makumi matatu, kusimba kwekuita kunoderera nekusapfuura 8%; mushure mekusangana nemafuta ejini, detergent, nezvimwewo, hapana kuzvimba kana kuputika, nepo PVC firimu iri nyore kuputika kana yaiswa mumafuta, uye PE firimu ichaparadzwa ne organic solvents. Zvichienderana nehunhu uhu, pamusoro peTPU firimu inogona kugadziridzwa nenzira dzakasiyana. Semuenzaniso, kurapwa kwechando kunogona kuvandudza skid resistance, iyo inoshandiswa kugadzira makesi ekudzivirira ezvigadzirwa zvemagetsi; kupfekedza neantibacterial layer kunogona kuwedzera hutsanana hunoita, hunoshandiswa pakudzivirira kwepamusoro kwemidziyo yekurapa; kusanganiswa ne hydrophilic coating kunogona kuvandudza kupenya kwemhepo, iyo inoshandiswa kugadzira machira ezvipfeko zvemitambo, nezvimwewo. Uyezve, izvi zvinogadziriswa marapirwo hazvikonzeri maitiro ekutanga emagetsi eTPU firimu.

Uye zvakare, iyo inodzivirira kuita kweTPU firimu inogona kugadziridzwa sezvinodiwa. Nekushandura density uye microporous chimiro, inogona kugadzirwa kuita firimu rinofema kwazvo rezvipfeko neminda yekurapa, richibvumira ganda remunhu kufema rakasununguka, uye zvakare rinogona kuburitsa yakanyanya airtight firimu rezvigadzirwa zvinoputika, kurongedza kwemvura, nezvimwewo, kuve nechokwadi chekuti gasi kana mvura haibvire. Semuenzaniso, mune inflatable mvura yepaki zvivako, TPU high-airtightness firimu inogona kuvimbisa kugadzikana kwekukwira kwemitengo yezvinhu uye kupa ruzivo rwakachengeteka uye rwakavimbika rwevaraidzo; mumachira ekupfeka maronda ekurapa, inofema zvakanyanya TPU firimu haingodzivise kupindira kwebhakitiriya asiwo kukurudzira kuchinjana kwegasi panguva yekupora maronda.

Kugadzirisa Kureruka uye Kuchengetedzwa Kwenzvimbo Yakanakira

TPU firimuine mashandiro akanaka ekugadzirisa uye inogona kugadzirwa kuita zvigadzirwa zvine ukobvu hwakasiyana (0.01-2mm) kuburikidza nemaitiro akasiyana senge extrusion, blow molding uye kukanda. Uyezve, zviri nyore kuita zvechipiri kugadzirisa sekuvhara kupisa, kukwira-frequency welding, kucheka uye kusona, nesimba rekubatana richisvika kupfuura 90% yezvigadziko zvega pachayo, uye kushanda kwekugadzirisa kuri 30% -50% yakakwirira kupfuura iyo yerabha firimu. Mukugadzira mikwende, TPU firimu rinogona kukurumidza uye zvakasimba kusanganiswa nezvimwe zvinhu kuburikidza nekupisa chisimbiso tekinoroji kugadzira mabhegi ezvikamu zvine basa rekusapinda mvura uye kusapfeka.

Panyaya yekuchengetedzwa kwezvakatipoteredza, TPU firimu rinoita zvakanakisa. Maitiro ayo ekugadzira haana muchetura plasticizer senge phthalates. Mushure mekuraswa, inogona kudzokororwa ne100% uye kugadzirwazve. Kana yapiswa, inongoburitsa CO₂ neH₂O, isina zvinosvibisa senge dioxins, uye inosangana neyakaomarara kuchengetedzwa kwemamiriro ekunze akadai seEU RoHS neREACH. Izvi zvinoita kuti TPU bhaisikopo ive sarudzo yakanaka yekutsiva zvinhu zvisina hushamwari kwezvakatipoteredza zvakaita sePVC, uye ine mukana mukuru webudiriro munharaunda yanhasi inoteerera kuchengetedzwa kwezvakatipoteredza. Semuenzaniso, mumunda wekurongedza chikafu, hunhu hwekuchengetedza kwezvakatipoteredza hweTPU firimu hunoigonesa kubata chikafu zvakachengeteka, kuve nechokwadi chehutano hwevatengi, uye kuderedza kusvibiswa kwezvakatipoteredza.

Minda Yekushandisa yeTPU Firimu

Medical Field

Nekuda kweiyo yakanaka biocompatibility uye zvimiro zvemuviri, TPU yakashandiswa zvakanyanya mundima yekurapa. Inogona kushandiswa kugadzira zvigadzirwa zvepamusoro zvekurapa senge yekugadzira moyo inobatsira michina, tsinga dzeropa dzekugadzira, uye ganda rekugadzira. Semuenzaniso, tsinga dzeropa dzekugadzira dzinoda kuve nekuchinjika kwakanaka, simba uye anticoagulability. TPU firimu rinongosangana nezvinodiwa izvi, rinogona kutevedzera elasticity uye michina zvimiro zvetsinga dzeropa revanhu, kuderedza njodzi yethrombosis, uye kugadzirisa hutano hwevarwere.

TPU firimu rinogonawo kushandiswa kugadzira machira ezviridzwa zvekuvhiya kuderedza kupesana pakati pezviridzwa uye matishu uye kuderedza kuvhiya kukuvadzwa; kugadzira mavharuvhu emwoyo ekugadzira kuti ave nechokwadi chakagadzikana uye chakavimbika kuvhura nekuvhara mabasa emavharuvhu; uye kuti ishandiswe mumagadzirirwo ekupa zvinodhaka kuti uwane mamwe maitiro ekurapa anobudirira nekunyatso kudzora mwero wekuburitswa kwezvinodhaka. Zvinogona kutaurwa kuti TPU firimu rinopa zvakakosha zvinhu rutsigiro rwekuvandudza tekinoroji yekurapa uye inosimudzira hunyanzvi uye kufambira mberi mundima yekurapa.
