Iindlela zoVavanyo lweNkqubo yokuFakwa kweSicelo sePowder

IINDLELA ZOKUVAVANYA UKUFAKA IIPHAWA

Iindlela zokuvavanya zenzelwe iinjongo ezimbini: 1. Ukuthembeka kokusebenza; 2. Ukulawulwa komgangatho

(1) UVAVANYO LOKULUNIKAZI (ASTM D523)

Uvavanyo oluqatywe iphaneli ecaba kunye Gardener 60 degree imitha. Ukwaleka akusayi kwahluka + okanye - 5% kwiimfuno zephepha ledatha kwinto nganye enikiweyo.

(2) UVAVANYO LOKUGOBA (ASTM D522)

Ukwaleka kwi .036 intshi etyebileyo phosphated panel yentsimbi iya kumelana 180 degree ukugoba phezu 1/4″ mandrel. Akukho crazing okanye ilahleko yokubambelela kunye nokugqiba kwi-gobe ikwazi ukususwa nge-3M Y-9239 tape.

(3) UVAVANYO LOBUNZIMA (ASTM D3363)

Iipensile zokhuni zeFaber Castell zisetyenziselwa ubulukhuni be-1,2,3,4,. Ukwaleka akusayi kubonisa manqaku ukusuka kwipensile ye-2H.

 (4) UVAVANYO LWE-CROSS HATCH ADHESION (ASTM D3359)

Bhalisa paralimigca ye-lel ngokusebenzisa i-coating ukuya kwi-substrate, i-1/4" ngaphandle komgama we-intshi enye. Bhalisa enye iseti parallel imigca 1/4″ ngaphandle kwaye perpendicular iseti yokuqala. Faka nayiphi na iteyiphu encangathi uze uyisuse kancinane. Iziphumo akufuneki zibe kukuphakanyiswa komgubo onyangisiweyo phakathi kwemigca yababhali.

(5) UVAVANYO LWENKCAZELO YEKHEMICAL (ASTM D1308)

Beka malunga namaconsi angama-10 e-solvent yovavanyo, equka i-95% nge-toluene yobunzima kunye ne-5% ngobunzima be-Methal Ethyl Keytone kumphezulu wengubo. Vumela ukuba ume imizuzwana engama-30. Zisule ngelaphu elithambileyo elomileyo. Ukwaleka akusayi kubonisa ngaphezu kophawu olusetyhula oluncinane.

(6) UVAVANYO LWEMPEMBELELO (ASTM D2794)

Ukwaleka kwi-.036 intshi engqindilili yephaneli yentsimbi yephosphated iya kumelana neempembelelo nge-1/2″ ibhola yomvavanyi wempembelelo ye-Gardener kwi-intshi ezingama-26 ephawundi ngqo nokubuya umva. Akukho madlelo okanye ukulahleka kokuncamathela. Ukugqiba akuyi kuba nako ukususwa kwindawo yempembelelo kunye ne-3M Y-9239 tape.

(7) UVAVANYO LOKUTSHYA ENTLUTHA (ASTM B117)

Sebenzisa isisombululo se-5% setyuwa kwi-92-97 degrees F kwikhabhinethi yemozulu evaliweyo. Scribe X kwintsimbi zinc phosphated uvavanyo panel ukuba zentsimbi. Hlola rhoqo iiyure ezingama-24. Ukugqiba uvavanyo kunye neeyure zizonke emva kwe-1/4 ″ creepage ukusuka kwindawo ebhaliweyo. I-Creepage ayinakudlula i-1/4″ kulo naliphi na icala ukusuka kumgca wababhali emva kokuvezwa kweeyure ezingama-500.
