Ikhoyili Egayiwe “Iguquka” Kanjani Ibe Umbala – Ikhoyili Ye-PPGI?

Emikhakheni eminingi efana nokwakha kanye nezinto zasekhaya, ama-PPGI Steel Coils asetshenziswa kabanzi ngenxa yemibala yawo ecebile kanye nokusebenza kahle kakhulu. Kodwa bewazi ukuthi "owandulelayo" yi-Galvanized Steel Coil? Okulandelayo kuzokwembula inqubo yokuthi i-Galvanized Sheet Coil ikhiqizwa kanjani ibe yi-PPGI Coil.

1. Ukuqonda Amakhoyili Ahlanganisiwe kanye Namakhoyili e-PPGI

Ama-Galvanised Coils Abakhiqizi bamboza ama-coils ngesendlalelo se-zinc ebusweni, esisebenza kakhulu ekuvimbeleni ukugqwala futhi sandisa impilo yenkonzo yensimbi. Ama-PPGI steel coils athatha ama-galvanised steel coils njenge-substrate. Ngemva kokucubungula ochungechungeni, kufakwa izembozo eziphilayo ebusweni bawo. Akugcini nje ngokugcina izakhiwo ezivimbela ukugqwala zama-galvanised steel coils kodwa futhi kunezela izakhiwo ezinhle kakhulu njengobuhle nokumelana nesimo sezulu.

 

2. Izinyathelo Ezibalulekile Zokukhiqiza Zefektri Yensimbi Egayiwe

(1) Inqubo Yokwelapha Ngaphambi Kokwelashwa - Ukususa Amafutha: Ubuso bezinsimbi zensimbi ezihlanganisiwe bungaba nokungcola okufana namafutha nothuli. Lokhu kungcola kususwa yizixazululo ze-alkaline noma ama-agent okususa amafutha amakhemikhali ukuqinisekisa inhlanganisela engcono yokugqoka okulandelayo ne-substrate. Isibonelo, ukusetshenziswa kwesisombululo sokususa amafutha esiqukethe i-surfactant kungabolisa ngempumelelo ama-molecule kawoyela.

Ukwelashwa Kokuguqulwa Kwamakhemikhali: Okuvamile kufaka phakathi ukwelashwa kwe-chromization noma i-chromium - passivation free. Kwakha ifilimu yamakhemikhali encane kakhulu ebusweni besendlalelo se-galvanized, ehlose ukuthuthukisa ukunamathelana phakathi kwe-substrate nopende ngenkathi ithuthukisa ukumelana nokugqwala. Le filimu ifana "nebhuloho", okwenza upende uxhumeke eduze ne-coil yensimbi ye-galvanized.

(2) Inqubo Yokupenda - I-Primer Coating: I-primer ifakwa ku-galvanized coil elungisiwe ngaphambilini ngokusebenzisa i-roller coating noma ezinye izindlela. Umsebenzi oyinhloko we-primer ukuvimbela ukugqwala. Iqukethe ama-pigment nama-resin alwa nokugqwala, angahlukanisa ngempumelelo ukuxhumana phakathi komswakama, umoya-mpilo, kanye nesendlalelo se-galvanized. Isibonelo, i-epoxy primer inokunamathela okuhle kanye nokumelana nokugqwala.

I-Topcoat Coating: Khetha i-topcoat coating enemibala ehlukene kanye nokusebenza kwayo ukuze ifakelwe ngokwezidingo. I-topcoat ayigcini nje ngokunika ikhoyili ye-PPGI imibala ecebile kodwa futhi inikeza isivikelo esifana nokumelana nesimo sezulu kanye nokumelana nokuguguleka. Isibonelo, i-polyester topcoat inemibala ekhanyayo kanye nokumelana okuhle kwe-UV, okwenza ifaneleke ukwakhiwa kwangaphandle. Amanye amakhoyili anombala nawo anopende wangemuva ukuvikela ingemuva le-substrate ekugugulekeni kwemvelo.

(3) Ukubhaka Nokuphola Umugqa wensimbi opendiwe ungena esithandweni sokubhaka bese ubhakwa ekushiseni okuthile (ngokuvamile 180℃ - 250℃). Izinga lokushisa eliphezulu lenza i-resin ependeni ibhekane nokusabela okuxhumene, iqine ibe yifilimu bese yakha ungqimba oluqinile. Isikhathi sokubhaka kanye nezinga lokushisa kumele kulawulwe ngokunembile. Uma izinga lokushisa liphansi kakhulu noma isikhathi singanele, ifilimu yopende ngeke iphole ngokuphelele, okuthinta ukusebenza; uma izinga lokushisa liphezulu kakhulu noma isikhathi side kakhulu, ifilimu yopende ingase ibe phuzi futhi ukusebenza kwayo kungase kwehle.

(4) Ukucutshungulwa Ngemva Kokucutshungulwa (Ongakukhetha) Amanye ama-coil ensimbi e-PPGI acutshungulwa ngemva kokukhishwa njengokufakwa kwe-embossing, ukufakwa kwe-laminating, njll. ngemva kokuphuma kuhhavini. Ukucutshungulwa kungandisa ubuhle bendawo kanye nokungqubuzana, kanti ukufakwa kwe-laminating kungavikela indawo yokumboza ngesikhathi sokuthuthwa kanye nokucubungula ukuze kuvinjelwe ukuklwebheka.

 

3. Izinzuzo kanye Nokusetshenziswa Kwama-PPGI Steel Coils Ngenqubo engenhla, i-galvanized steel coil "iguqulwa" ngempumelelo ibe yi-PPGI coil. I-PPGI Coil inhle futhi iyasebenza. Emkhakheni wokwakha, ingasetshenziswa ezindongeni zangaphandle kanye nophahla lwezimboni. Ngemibala ehlukahlukene, ihlala isikhathi eside futhi ayibuni. Emkhakheni wezinto zasekhaya, njengeziqandisi namagobolondo omoya-conditioner, zombili ziyathandeka futhi ziyaguga. Ukusebenza kwayo okuhle kakhulu okubanzi kwenza ithathe indawo ebalulekile ezimbonini eziningi. Kusukela ku-galvanized coil kuya ku-PPGI coil, ukuguqulwa okubonakala kulula empeleni kuhilela ubuchwepheshe obuqondile kanye nefomula yesayensi. Isixhumanisi ngasinye sokukhiqiza sibalulekile, futhi ndawonye bakha ukusebenza okuhle kakhulu kwe-PPGI coil, benezela umbala kanye nokulula embonini yanamuhla kanye nokuphila.
