I-Galvanized Coil "Itshintsha" Njani I-Color - PPGI Coil?

Kwimimandla emininzi efana nokwakha kunye nezixhobo zasekhaya, iiPPGI Steel Coils zisetyenziswa kakhulu ngenxa yemibala yazo etyebileyo kunye nokusebenza kakuhle. Kodwa ngaba ubusazi ukuba "owandulelayo" yiGalvanized Steel Coil? Oku kulandelayo kuza kutyhila inkqubo yendlela iGalvanized Sheet Coil eyenziwa ngayo ibe yiPPGI Coil.

1. Ukuqonda iikhoyili zeGalvanised kunye neekhoyili zePPGI

Abavelisi beekhoyili zeGalvanised bagquma iikhoyili ngomaleko we-zinc phezu komphezulu, osebenza kakhulu njengomsebenzi wokumelana nomhlwa kwaye wandisa ubomi benkonzo yentsimbi. Iikhoyili zentsimbi zePPGI zithatha iikhoyili zentsimbi zegalvanised njengesiseko. Emva kokucubungula uthotho, ii-organic coatings zifakwa kumphezulu wazo. Ayigcini nje ngokugcina iipropati zokumelana nomhlwa zeekhoyili zentsimbi zegalvanised kodwa ikwafaka iipropati ezintle ngakumbi ezifana nobuhle kunye nokumelana nemozulu.

 

2. Amanyathelo aPhambili eMveliso yeFektri yeNtsimbi eGqityiweyo

(1) Inkqubo Yonyango Ngaphambi Konyango - Ukususa Amafutha: Umphezulu weekhoyili zentsimbi ezigayiweyo unokuba nokungcola okufana neoyile nothuli. Ezi zinto zingcolisayo zisuswa zizisombululo ze-alkaline okanye ii-arhente zokususa amafutha ngokweekhemikhali ukuqinisekisa indibaniselwano engcono yokwambathisa okulandelayo kunye ne-substrate. Umzekelo, ukusetyenziswa kwesisombululo sokususa amafutha esine-surfactant kunokubolisa ngempumelelo iimolekyuli zeoyile.

Unyango lokuguqulwa kweekhemikhali: Eziqhelekileyo ziquka unyango lwe-chromization okanye i-chromium-free passivation. Yenza ifilimu encinci kakhulu yekhemikhali kumphezulu womaleko we-galvanized, ejolise ekuphuculeni ukunamathelana phakathi kwe-substrate kunye nepeyinti ngelixa iphucula ngakumbi ukumelana nokugqwala. Le filimu ifana "nebhulorho", evumela ukuba ipeyinti idityaniswe ngokusondeleyo ne-coil yentsimbi ye-galvanized.

(2) Inkqubo yokupeyinta - I-Primer Coating: I-primer ifakwa kwi-galvanized coil elungisiweyo ngaphambili ngokusebenzisa i-roller coating okanye ezinye iindlela. Umsebenzi ophambili we-primer kukuthintela ukugqwala. Iqulethe ii-pigments ezichasene nokugqwala kunye nee-resins, ezinokwahlula ngokufanelekileyo unxibelelwano phakathi komswakama, i-oksijini, kunye nomaleko we-galvanized. Umzekelo, i-epoxy primer inokunamathela okuhle kunye nokumelana nokugqwala.

Ukwaleka kweTopcoat: Khetha ukwaleka kwetopcoat okunemibala eyahlukeneyo kunye nokusebenza kokukwaleka ngokweemfuno. Itopcoat ayigcini nje ngokubonelela ngemibala etyebileyo kwi-PPGI coil kodwa ikwabonelela ngokhuseleko olufana nokumelana nemozulu kunye nokumelana nokuguguleka. Umzekelo, i-polyester topcoat inemibala eqaqambileyo kunye nokumelana okuhle kwe-UV, okwenza ifaneleke ukwakhiwa ngaphandle. Ezinye ii-coils ezinemibala zikwanayo nepeyinti yangasemva ukukhusela umva we-substrate ekukhukulisekeni kwendalo.

(3) Ukubhaka nokuCoca Umcu wentsimbi opeyintiweyo ungena kwisithando sokubhaka kwaye ubhakwa kubushushu obuthile (ngesiqhelo yi-180℃ - 250℃). Ubushushu obuphezulu benza i-resin epeyintini idlule kwi-cross-linking reaction, iqina ibe yifilimu kwaye yenze i-coating eqinileyo. Ixesha lokubhaka kunye nobushushu kufuneka kulawulwe ngokuchanekileyo. Ukuba ubushushu buphantsi kakhulu okanye ixesha alanelanga, ifilimu yepeyinti ayizukunyangeka ngokupheleleyo, nto leyo echaphazela ukusebenza; ukuba ubushushu buphezulu kakhulu okanye ixesha lide kakhulu, ifilimu yepeyinti inokutshintsha ibe tyheli kwaye ukusebenza kwayo kunokwehla.

(4) Ukucubungula emva (Ukhetho) Ezinye iikhoyili zentsimbi zePPGI ziyacutshungulwa emva kwexesha ezifana nokugquma, ukugquma, njl.njl. emva kokuphuma kwi-oven. Ukucoca kunokunyusa ubuhle bomphezulu kunye nokungqubana, kwaye ukugquma kunokukhusela umphezulu wokugquma ngexesha lokuthuthwa kunye nokucubungula ukuthintela imikrwelo.

 

3. Iingenelo kunye nokusetyenziswa kwee-PPGI Steel Coils Kule nkqubo ingentla, i-galvanized steel coil "iguqulwa" ngempumelelo ibe yi-PPGI coil. I-PPGI Coil intle kwaye iyasebenza. Kwicandelo lokwakha, ingasetyenziselwa iindonga zangaphandle kunye nophahla lweefektri. Ngemibala eyahlukeneyo, zihlala ixesha elide kwaye azipheli. Kwicandelo lezixhobo zasekhaya, ezifana neefriji kunye neegobolondo ze-air-conditioner, zombini ziyathandeka kwaye ziyaguga. Ukusebenza kwayo okugqwesileyo okubanzi kwenza ukuba ithathe indawo ebalulekileyo kumashishini amaninzi. Ukusuka kwi-galvanized coil ukuya kwi-PPGI coil, utshintsho olubonakala lulula ngokwenene lubandakanya itekhnoloji echanekileyo kunye nefomyula yesayensi. Ikhonkco ngalinye lemveliso liyimfuneko, kwaye ngokudibeneyo benza ukusebenza okuhle kwe-PPGI coil, bongeza umbala kunye nokulula kushishino lwanamhlanje kunye nobomi.
