Dheti: 2022-12-19


Kune "pseudo-yellowing" inokonzerwa ne stain attachment:

Imwe yero inokonzerwa neguruva, mavara akawira pamuviri wemotokari haana kuchenesa nenguva. Nekuda kwechikonzero cheyero ichi, inobvisa tsvina isina kwayakarerekera isina abrasive inogona kushandiswa kunyatso kuchenesa mota kuyedza kuibvisa. Usapukuta kunze kwekunge zvichidikanwa, sezvo kupurisa kunogona kukuvadza iyo yekutanga yekudzivirira yekuvhara uye kukonzera matambudziko matsva. Pseudo-yellowing inowanzove yenzvimbo yero, asi kana guruva uye tsvina ikapinda zvachose muTPU substrate, pane mukana wekuti haigone kubviswa.

 

Nekutsvuka kunokonzerwa ne substrate glue:

Iyo yero yakakonzerwa nekusarudzika kwakashata kweTPU substrate uye glue kazhinji inzvimbo yakakura yero, iyo isingadzokerike. Zvinonzi chitoro chitaurirane nemuridzi kuti chibvise marepas nekukasika.

Zvinoda kusimbiswa pano kuti kutsvuka kweTPU substrate, kupeta kana kutsvuka kwenhema kunokonzerwa nemarara eguruva kunogona kutungamira kune mhedzisiro yekubvaruka kwefirimu uye kumisa, asi kutsvuka kweglue kune njodzi yakanyanya, uye kuita kwemakemikari pakati peglue. uye pendi yemotokari ine mukana wekukuvadza pendi yemotokari.

 

Nzira yekudzivirira sei pachena PPF yero?

Yellowing chiitiko chepanyama. Pasi pekuita kwenguva, hazvigoneke kuti PPF isaite yero zvachose. Naizvozvo, pano isu tinongokurukura maitiro ekudzora yellowing index yePPF yakajeka mukati meiyo indasitiri chiyero chiyero 2 (kutsvedza discoloration):

Chekutanga, yePPF yakagadzirwa nePVC, TPH uye inonhuhwirira TPU zvinhu, kutsvuka hakudzivisiki, uye kunowanzoitika mukati memwedzi mitanhatu kusvika kumakore maviri.Aliphatic TPU zvinhu zvinofanirwa kufarirwa kudzivirira kutsvuka kweiyo substrate.Ziva kuti kumhanyisa kweyero kwealiphatic TPU zvinhu zvemhando dzakasiyana kwakasiyanawo, izvo zvinoda kuti fekitori yekukanda uye yekuputira fekitori kuti inyatso sarudza substrate zvimedu zvinoenderana neyakapfuura indasitiri ruzivo.

Kusarudzwa kwePPF glue kune yakasarudzika huru. Mafekitari ekuputira anofanirwa kusarudza mhando dzeglue uye mhando dzakaedzwa zvizere uye dzakasimbiswa nemusika, uye chenjera kushandisa mamwe mabhureki eglue asina kunyatsoedzwa uye kusimbiswa nemusika.

Miitiro yakanaka yemotokari inokoshawo zvikuru.Zvinokurudzirwa kuti muridzi wemotokari ashambidze motokari kanenge kamwe chete vhiki mbiri uye kuenda kuchitoro mwedzi mitanhatu yega yega kuchengetedza firimu rinodzivirira repende yemotokari. Izvi zvinogona nesezvinogoneka kudzivirira kudzika kwepasi stain kupinda mu substrate, zvichikonzera "yero yenhema" kune "yero yechokwadi".
