Izindlela Zokuhlola Zenqubo Yokufaka Isicelo Se-Powder Coating

IZINDLELA ZOKUHLOLA IMPAPHU YOPHUVA

Izindlela zokuhlola zenzelwe izinhloso ezimbili: 1. Ukuthembeka kokusebenza; 2. Ukulawulwa kwekhwalithi

(1) ISIHLOMELO SOKUGCINA (ASTM D523)

Hlola iphaneli eyisicaba ene-Gardener 60 degree meter. Ukugqoka akufanele kuhluke + noma - 5% ezidingweni zedatha yedatha kunto ngayinye enikeziwe.

(2) ISIVIVINYO SOKUGOBA (ASTM D522)

I-coating on .036 inch thick phosphated steel panel izomelana nokugoba okungu-180 degree phezu kwe-1/4″ mandrel. Akukho ukuhlanya noma ukulahleka kokunamathela kanye nokuqedwa ekujikeni kungasuswa ngeteyipu engu-3M Y-9239.

(3) UBUNZIMA (ASTM D3363)

Amapensela okhuni e-Faber Castell asetshenziswa ebukhuni be-1,2,3,4,. I-coating akufanele ibonise amamaki avela kupensela elingu-2H.

 (4) I-CROSS HATCH ADHESION TEST (ASTM D3359)

Bhala paralimigqa ye-lel ngokusebenzisa i-coating kuya ku-substrate, 1/4″ ngokuhlukana ngebanga eliyi-intshi eyodwa. Bhala elinye iqoqo paralimigqa ye-lel engu-1/4″ ngokuhlukana futhi i-perpendicular kusethi yokuqala. Faka noma iyiphi itheyiphu enamathelayo bese uyisusa kancane. Imiphumela akufanele ibe ukuphakanyiswa kwempushana eselashiwe phakathi kwemigqa yababhali.

(5) TEST CHEMICAL REISTANCE (ASTM D1308)

Beka cishe amaconsi angu-10 e-solvent yokuhlola, ehlanganisa u-95% ngesisindo se-toluene kanye no-5% ngesisindo i-Methal Ethyl Keytone phezu kwento enamathelayo. Vumela ukuma imizuzwana engu-30. Sula ngendwangu ethambile, eyomile. Ukumboza ngeke kubonise ngaphezu kophawu oluyindilinga oluncane.

(6) ISIVIVINYO SOMTHELELA (ASTM D2794)

Ukufakwa kuphaneli yensimbi engu-.036 inch ewugqinsi we-phosphated kuzomelana nomthelela ngebhola elingu-1/2″ lokuhlola ithonya lasengadini kumaphawundi angu-26 intshi ngokuqondile nokuhlehlayo. Awekho amadlelo noma ukulahlekelwa ukunamathela. I-Qeding ngeke ikwazi ukususwa endaweni enomthelela nge-3M Y-9239 tape.

(7) UKUHLOLA KOKUGULA KWE-SALT SPRAY (ASTM B117)

Sebenzisa isisombululo sikasawoti esingu-5% ku-92-97 degrees F kukhabhinethi yesimo sezulu evaliwe. Bhala u-X kuphaneli yokuhlola ye-zinc phosphated yensimbi engenalutho. Hlola njalo emahoreni angama-24. Qeda uhlolo kanye nesamba samahora ngemuva kwe-1/4″ creepage endaweni ebhaliwe. I-Creepage akufanele idlule u-1/4″ kunoma iyiphi indlela ukusuka kulayini wababhali ngemva kokuchayeka kwamahora angu-500.
