PECOAT Polyethylene Powder Coating bakeng sa Pipe ea Metsi a Noang

PECOAT® Polyethylene Powder Coating bakeng sa lipeipi tsa metsi a nooang le lisebelisoa tsa phepelo ea metsi

Tlhaloso

Sekoahelo sa phofo sa polyethylene se inehetseng metsing a nooang ke sekoahelo sa phofo sa thermoplastic se lokisitsoeng ka resin ea polyethylene, compatibilizer, li-additives tse sebetsang, li-pigment le li-filler. Se lekiloe ka botlalo 'me sa hlahlojoa bakeng sa bohloeki le polokeho, 'me se ka sebelisoa bakeng sa ho koahela mocheso o tloaelehileng lisebelisoa tsa phepelo ea metsi a nooang le liphaephe. ​​Se na le botsitso bo botle ba lik'hemik'hale, ho thibela motlakase le ho hanyetsa mocheso o tlase, hammoho le ho hanyetsa mafome le ho tšoarella ho babatsehang. Sehlahisoa se latela CJ/T 120-2016 "Metseng ea Kaho ea Metseng" ea Rephaboliki ea Batho ba Chaena.

Field kopo

Ho roala ho loketse bakeng sa lisebelisoa tsa phepelo ea metsi a nooang a mocheso le liphaephe.

Thepa ea phofo

• Litaba tse sa fetoheng: ≥99.5%
• Ho phalla ha metsi: 20%
• Matla a khoheli a khethehileng: 0.91-0.95 (e fapana ka 'mala)
• Kabo ea boholo ba likaroloana: ≤300um
• Qhibiliha index: 5-20g/10min (2.16kg, 190 ℃) [ho ipapisitse le mosebetsi oa ho roala le ts'ebetso ea bareki]
• Polokelo: ka matlung a ka tlase ho 35 ℃, e nang le moea o pholileng le e omileng, hole le mehloli ea mollo. Nako ea polokelo ke lilemo tse peli ho tloha letsatsing la tlhahiso. Kamora ho felloa ke nako, e ntse e ka sebelisoa haeba e feta tlhahlobo hape. E boetse e kgothaletswa ho latela molao-motheo oa pele oa ho sebelisa sehlahisoa.
• Packaging: sephutheloana sa mekotla ea pampiri e kopantsoeng, se nang le boima ba nete ba 20 kg mokotla ka mong.

kopo Instructions

• Phekolo ea pele: Pele ho roaloa, phala ea motheo e tlameha ho phekoloa ka mekhoa e kang sandblasting kapa pickling acid le phosphating ho tlosa mafome, oli le filimi ea oxide holim'a tšepe ea motheo le lesela la galvanized.
• Workpiece preheating mocheso: 230-280 ℃ [fetoha ho ea ka bophara phala].
• Mokhoa oa ho roala: ho koaheloa ka vacuum kapa ho roala.
• Ka mor'a mocheso: 180-220 ℃, metsotso ea 0-5 [etsa qeto ea mokhoa oa polasetiki ho ea ka bophara ba phala le boreleli ba ho roala. Ho futhumatsa le ho etsa polasetiki ho molemo ho fumana lesela le boreleli holim'a tšepe ea tšepe].
• Cooling/ Ketso ya ho phodisa: ho phodisa moya kapa ho phodisa ka tlhaho.

Temoso

1. Ho finyella ho khomarela hantle, ho kgothaletswa ho etsa phosphating kapa phekolo ea chromizing holim'a lisebelisoa tsa motheo ka mor'a ho senya le ho tlosoa ha mafome.

2. Ho futhumala ho feteletseng ho tla baka botsofali le ho fetoha ha 'mala oa ho roala, ha mocheso o tlaase haholo o tla fella ka ho koaheloa ha phofo e futsanehileng le ho roala ho sa tšoaneng. Ka hona, mocheso o nepahetseng oa ho futhumatsa o lokela ho khethoa ka liteko tse thehiloeng ho botenya ba tšepe le lisebelisoa tsa ho roala bareki.

3. Moralo oa mosebetsi: likarolo tse bohale li lokela ho lokisoa, 'me ha hoa lokela ho ba le likheo ho li-welding manonyeletso. Botenya ba tšepe le bophara ba terata holim'a workpiece e tšoanang e lokela ho tšoana.

4. Sehlahisoa sena ha se kgothaletswe ho sebelisoa ka mor'a ho sebetsa (ho fetola li-workpieces tse koahetsoeng).

5. Joaloka li-polymer powders tsohle, haholo-holo maemong a phallang, phofo ena e ka chesa kapa ea chesa ha e kopana le mohloli oa mocheso kapa sesebelisoa sa mollo.
