Yemhando yepamusorofirimu rekudzivirira pendi (PPF)Inoshandisa Thermoplastic Polyurethane (TPU) sechinhu chikuru chepakutanga, icho chinosarudza kugara kwenguva refu kwefirimu, runako rwayo, uye mashandiro ayo. Parizvino, TPU inonyanya kuiswa muzvikamu zviviri zvemhando dze aliphatic ne aromatic, musiyano wavo mukuru uri mu "yellowing resistance." Tafura iri pazasi inoratidza zvakajeka musiyano mukuru pakati pemhando mbiri dzeTPU:
| Hunhu | TPU yeAliphatic | TPU inonhuhwirira |
|---|---|---|
| Maumbirwo emakemikari | Haina mhete dzebenzene (semuenzaniso, dzakavakirwa paHDI), dzakagadzikana muchimiro. | Ine zvivakwa zvemhete dzebenzene (semuenzaniso, zvichibva paMDI). |
| Zvinhu Zvikuru | Kuramba kweyero kwakanaka: Kuramba kwenguva refu kutsvinyirwa nemwaranzi yeUV, nenguva dzewarandi dzinogara dzichipfuura makore gumi. Maumbirwo akasimba: Kuwanda kwemamorekuru ekurongedza, zvichipa kusimba kuri nani pakukwenya nekukwenya, pamwe nekusimba kwakanyanya uye kusimba kwekukwenya. | Zvinowanzoita yero: Mhete dzeBenzene dzinogona kuoxida kana dzasvikwa neUV, zvichigona kukonzera yero inoonekwa mukati memakore 3-5. Kuchinjika kwakanaka, asi kazhinji hazvina simba uye hazvigoni kukwenywa kana zvichienzaniswa nedzemhando dze aliphatic. |
| Nzvimbo yeMusika | Zvinhu zvepakutanga zvePPF yepamusoro, zvichidhura zvakanyanya. | Zvinhu zvakajairika zvePPF yepakati kusvika pasi, zviri nyore kutenga. |
Zvimwe Zvikamu zveTPU uye Kuumbwa kwePPF
Kupfuura mapoka ari pamusoro apa, TPU inogonawo kuiswa muzvikamu zvayo zvakapfava muzvikamu zve polyester-based uye polyether-based. TPU yakavakirwa papolyester inopa simba riri nani, kuramba kukwesha, uye kuramba mafuta; TPU yakavakirwa papolyether inopa kuramba kunyungudika kwehydrolysis kwepamusoro uye kuchinjika kwekupisa kwakaderera. Zvinhu zvemazuva ano zvePPF base zvinowanzoshandisa maformula akagadziridzwa kuti aenzane nehunhu uhwu. PPF yakakwana ichimiro chine mativi akawanda. Kunze kweTPU base layer, inosanganisira:
- Adhesive Layer: Inoita kuti pave nekubatana kwakasimba uye kubviswa kwependi isina marara pasina kukuvadza pendi yepakutanga. Inoda simba rakasimba rekubatanidza uye kuramba UV. Zvigadzirwa zvepamusoro zvinotarisawo pakudzivirira kufamba kwepurasitiki kudzivirira kutadza kushanda kweadhesive.
- Koti Yepamusoro Inoshanda: Chikamu chekunze, chinoona zvakananga ruzivo rwemushandisi. Mabasa makuru anosanganisira kuzvikwenya (zvichienderana nehydrogen bonds mukati mekoti inogadzirisa mavanga madiki nekupisa), hunhu hwe hydrophobic uye oleophobic (hunoita kuti kuchenesa kuve nyore), uye kupa mhedzisiro yekuona senge kupenya kwakanyanya kana matte finishes.
Maitiro Ekusarudza Uye Kutengesa Mafambiro
Pakusarudza PPF, kunze kwekusimbisa kushandiswa kwe aliphatic TPU, unogona zvakare kufunga nezve:
- Tarisa Waranti Yepamutemo: Zvigadzirwa zveTPU zve aliphatic zvinovimbika zvinowanzouya newarandi yepamutemo yemakore gumi kana kupfuura, zvichivimbisa pachena kuti hazvizoiti kuti yellowing ishande zvakanaka.
- Tarisa paTekinoroji yeTop Coat: Top coat ine chekuita nekusada mvura, kushanda kwayo pakuzvirapa, uye kurarama kwenguva refu. Bvunza nezvemashandiro chaiwo ejasi.
- Chenjerera Misungo Yemitengo Yakaderera: Chenjerera zvinotaurwa nezve "aliphatic TPU" pamitengo yakaderera zvisingawanzoitiki, sezvo zvingave zvisina kururama.
Panyaya yemafambiro, nekuwedzera kwekuda kwevatengi kwemhando yepamusoro uye kugara kwenguva refu, TPU yemhando yepamusoro inoshanda, inomiririrwa nezvinhu zvakaita seLINGHUA TPU series, yava kuva sarudzo huru mumusika.
