Koira yeGalvanized "Inoshanduka" Sei kuita Ruvara - PPGI Coil?

Muminda yakawanda yakaita sekuvaka nemidziyo yemumba, PPGI Steel Coils inoshandiswa zvakanyanya nekuda kwemavara ayo akapfuma uye mashandiro ayo akanaka. Asi waizviziva here kuti "yakatangira" ndiyo Galvanized Steel Coil? Zvinotevera zvicharatidza maitiro ekugadzirwa kweGalvanized Sheet Coil kuita PPGI Coil.

1. Kunzwisisa Makoiri Akagayiwa uye Makoiri ePPGI

Vagadziri veMagetsi Akakombama vanofukidza magetsi ne zinc layer pamusoro, iyo inonyanya kushanda senzira yekudzivirira ngura uye inowedzera hupenyu hwesimbi. Magetsi esimbi ePPGI anotora magetsi esimbi akakombama se substrate. Mushure mekugadzirisa kakawanda, mapeti eorganic anoiswa pamusoro pawo. Haangochengetedzi chete hunhu hwemagetsi esimbi akakombama asi anowedzerawo hunhu hwakanaka hwakadai serunako uye kuramba mamiriro ekunze.

 

2. Matanho Akakosha Ekugadzira Fekitori Yesimbi Yakagadzikwa

(1) Maitiro Ekugadzirisa - Kubvisa mafuta: Pamusoro pesimbi dzakagadzirwa nesimbi dzakagadzirwa nesimbi dzinogona kunge dzine tsvina yakaita semafuta neguruva. ​​Zvinosvibisa izvi zvinobviswa nealkaline solutions kana makemikari anobvisa mafuta kuti zvive nechokwadi chekuti kuputira kunotevera kwakabatana zvakanaka ne substrate. Semuenzaniso, kushandisa solution inobvisa mafuta ine surfactant kunogona kuodza mamorekuru emafuta zvinobudirira.

Kurapa Kuchinja Kwemakemikari: Kurapa kwakajairika kunosanganisira chromization kana chromium - free passivation treatment. Inogadzira firimu remakemikari rakatetepa pamusoro pegwaro remagalasi, nechinangwa chekuwedzera kunamira pakati pe substrate nependi uku ichivandudza kuramba kwengura. Firimu iri rakaita se "bhiriji", zvichiita kuti pendi ikwanise kubatana zvakanyanya nesimbi yegalvanized coil.

(2) Maitiro Ekupenda - Kupenda Kwekutanga: Iyo primer inoiswa pa galvanized coil yakagadziriswa kare kuburikidza ne roller coating kana dzimwe nzira. Basa guru re primer nderekudzivirira ngura. Ine pigments dzinorwisa ngura uye resins, izvo zvinogona kuparadzanisa zvinobudirira kusangana pakati pehunyoro, okisijeni, uye galvanized layer. Semuenzaniso, epoxy primer ine kunamira kwakanaka uye inodzivirira ngura.

Kupenda Topcoat: Sarudza mapende e topcoat ane mavara akasiyana uye mashandiro ekupenda zvichienderana nezvinodiwa. Topcoat haingogumiri pakuisa PPGI coil nemavara akapfuma asiwo inopa dziviriro yakadai sekudzivirira mamiriro ekunze uye kudzivirira kupera. Semuenzaniso, polyester topcoat ine mavara akajeka uye kudzivirira UV zvakanaka, zvichiita kuti ikodzere kuvakwa panze. Mamwe mapende akafukidzwa nemavara anewo pendi yekumashure kudzivirira kumashure kwe substrate kubva mukukukurwa kwezvakatipoteredza.

(3) Kubika uye Kugadzira Chidimbu chesimbi chakapendwa chinopinda muchoto chekubikira uye chinobikwa patembiricha yakati (kazhinji 180℃ - 250℃). Tembiricha yakanyanya inoita kuti resin iri mupendi ipinde muchikamu chekubatanidza, ichioma kuita firimu uye ichigadzira coating yakasimba. Nguva yekubikira uye tembiricha inofanira kudzorwa nemazvo. Kana tembiricha yakaderera zvakanyanya kana nguva isina kukwana, firimu rependi harizorapwa zvachose, zvichikanganisa mashandiro; kana tembiricha yakanyanya kana nguva yakareba, firimu rependi rinogona kuita yero uye mashandiro aro anogona kudzikira.

(4) Kugadziriswa mushure mekushanda (Sarudzo) Mamwe ma PPGI Steel coils anogadziriswa mushure mekushanda sekunge anogadzirwa nemaoko, anoiswa mupurasitiki, nezvimwewo mushure mekubuda muovheni. Kuiswa mupurasitiki kunogona kuwedzera runako rwepamusoro uye kukweshana, uye kuiswa mupurasitiki kunogona kuchengetedza pamusoro pepurasitiki panguva yekufambisa nekugadzirisa kudzivirira kukweshana.

 

3. Zvakanakira uye Mashandisirwo ePPGI Steel Coils Kuburikidza nemaitiro ari pamusoro apa, galvanized steel coil inoshandurwa zvinobudirira kuita PPGI coil. PPGI Coil yakanaka uye inoshanda. Mubasa rekuvaka, inogona kushandiswa pamadziro ekunze nematenga emafekitori. Nemavara akasiyana-siyana, inogara kwenguva refu uye haiperi. Mubasa remidziyo yemumba, senge mafiriji nemagoko emhepo inotonhodza, ese ari maviri anofadza uye haaparare. Kushanda kwayo kwakanaka kwazvo kunoita kuti ive nechinzvimbo chakakosha mumaindasitiri mazhinji. Kubva pagalvanized coil kusvika paPPGI coil, shanduko inoita kunge iri nyore inosanganisira tekinoroji chaiyo uye fomura yesainzi. Chinobatanidza chega chega chekugadzira chakakosha, uye pamwe chete vanogadzira kushanda kwakanaka kwePPGI coil, vachiwedzera ruvara uye nyore kune indasitiri yemazuva ano nehupenyu.
