Kuti unyatsoshandisa chigadzirwa, munhu anofanira kutanga anzwisisa zvakanaka, uye mavara akafukidzwa nemapumburu haana mutsauko. Zvadaro, ngatizvizivise pachedu kune mavara akaputirwa rolls.
Chekutanga, isu tinofanirwa kuziva kuti bhodhi rakavharwa ruvara chii?
Ruvara rwakavharwa nesimbi tambo uchishandisa inopisa-dhipi yakabatiswa simbi tambo sezvo substrate isina chete zinc layer yekudzivirira, asiwo ine organic coating pazinc layer yekuvhara nekudzivirira, ichidzivirira simbi tambo kubva ngura. Hupenyu hwayo hwesevhisi hurefu hwakapetwa ka1.5 pane hwemarata esimbi. Chechipiri, isu tinofanirwa kutanga tanzwisisa zvinangwa zvemavara akashongedzwa rolls? Mavara akavharidzirwa akareruka, anoyevedza anoyevedza, uye ane yakanaka corrosion resistance. Iwo anogona zvakare kugadziriswa zvakananga uye anowanzo kuwanikwa mumumvuri wegrey chena, yegungwa bhuruu, uye zvidhinha zvitsvuku. Iwo anonyanya kushandiswa mukushambadzira, kuvaka, midziyo yemumba, fenicha, uye maindasitiri ezvekufambisa.
Iyo yekuputira inoshandiswa kune mavara akavharidzirwa rolls inofanira kusarudza resin akakodzera zvichienderana nenzvimbo dzakasiyana dzemashandisirwo, senge polyester silicon yakagadziridzwa polyester, polyvinyl chloride plastiki sol, polyvinylidene chloride, etc. Vashandisi vanogona kusarudza zvinoenderana nezvavanoda kushandisa. Tevere, iwe unofanirwa kuziva iyo coating chimiro:
V yekuputira chimiro chemhando
2/1: Isa kaviri pamusoro pepamusoro, kamwe pazasi, uye bika kaviri.
2/1M: Isa kaviri panzvimbo yepamusoro nepamusoro, uye bika kamwe chete.
2/2: Isa kaviri panzvimbo yepamusoro nepamusoro, uye bheka kaviri.
Kushandiswa kwezvakasiyana zvekupfeka zvimiro:
2/1: Kuramba kwecorrosion uye kuramba kwependi ye-single-layer back paint haina kunaka, asi ine yakanaka yekunamatira uye inonyanya kushandiswa mumasangweji mapaneru;
2/1M: Pendi yekumashure ine yakanaka corrosion kuramba, kukwenya kuramba, uye kugadzirisa kuumbwa, nekunamira kwakanaka, kwakakodzera kune imwechete-layer profiled mapaneru uye masangweji mapaneru.
2/2: Iyo kaviri-layer kumashure pendi ine yakanaka corrosion kuramba, kukwenya kuramba, uye kugadzirisa formability, uye inonyanya kushandiswa kune imwechete-layer profiled mapaneru. Nekudaro, kunamatira kwayo kwakashata uye haina kukodzera masangweji mapaneru.
Ndezvipi zvikamu zvemavara akavharidzirwa substrates?
Hot dip galvanized substrate
Chigadzirwa chinowanikwa nekuisa organic coating pane inopisa-dip galvanized steel sheet inopisa-dip galvanized color coated sheet. Kupisa dip galvanized color coated sheet haingove nekudzivirira kwe zinc, asi iyo organic coating pamusoro pepamusoro inoitawo basa mukudzivirira kwekudzivirira uye kudzivirira ngura, nehupenyu hurefu hwesevhisi pane inopisa-dhip galvanized sheet. Iyo zinc yemukati inopisa-dip galvanized substrates inowanzoita 180g/m2 (double-sided), uye iyo zinc yepamusoro yehot-dip galvanized substrates yekushandiswa kwekunze muzvivakwa i275g/m2.
Kupisa dip aluminium zinc substrate
Kupisa dip aluminium zinc simbi ndiro (55% Al Zn) inoshandiswa seyachangobva kuvharwa substrate, kazhinji ine aluminum zinc yemukati ye150g/㎡ (yakapetwa kaviri). Kupokana kwe-hot-dip aluminium zinc sheet ndeye 2-5 nguva kune inopisa-dip galvanized sheet. Kuenderera mberi kana kupindirana kushandiswa patembiricha inosvika 490 ℃ hakuzokonzeresa oxidation yakanyanya kana kuumbwa kwezvikero zveoxide. Kugona kuratidza kupisa uye kupenya kwakapetwa kaviri kune inopisa-dip galvanized simbi ndiro, uye ratidziro yakakura kupfuura 0.75 chinhu chakanakira kuvaka chekuchengetedza simba.
Electroplated galvanized substrate
Chigadzirwa chinowanikwa nekushandisa electroplated galvanized sheet se substrate uye kuibika ne organic coating is electroplated galvanized color coated sheet. Nekuda kwekutetepa zinc layer ye electroplated galvanized sheet, iyo zinc yemukati inowanzo 20/20g/m2, saka chigadzirwa ichi hachina kukodzera kushandiswa kunze mukugadzira madziro, matenga, nezvimwewo. inogona kunyanya kushandiswa midziyo yemumba, maredhiyo, fenicha yesimbi, kushongedza kwemukati, zvichingodaro. Pakunzwa izvi, une ruzivo here nezvemapepa akaiswa mavara? Kana uchifarira, huya utibvunze isu!
