Izindlela Zokuhlola Ezijwayelekile Zokulinganisa Ukunamathela ngeTape Test

Izindlela Zokuhlola Zokulinganisa Ukunamathela

Leli zinga likhishwa ngaphansi kwegama elimisiwe elithi D 3359; inombolo ngokushesha elandela ukuqokwa ikhombisa unyaka wokutholwa kwasekuqaleni noma, esimweni sokubuyekeza, unyaka wokubuyekeza okokugcina.Inombolo ekubakaki ikhombisa unyaka wokugunyazwa kabusha kokugcina. I-epsilon ye-superscript (e) ibonisa ushintsho lokuhlela kusukela ekubuyekezweni kokugcina noma ukugunyazwa kabusha.

1. Ububanzi

1.1 Lezi zindlela zokuhlola zihlanganisa izinqubo zokuhlola ukunamathela kwamafilimu okunamathela metallic ama-substrates ngokufaka nokususa itheyiphu ezwela ukucindezela phezu kokusikeka okwenziwe kwifilimu.
1.2 Indlela Yokuhlola A ngokuyinhloko ihloselwe ukusetshenziswa ezindaweni zokusebenza kuyilapho Indlela Yokuhlola B ifaneleka kakhulu ukusetshenziswa elabhorethri. Futhi, Indlela Yokuhlola B ayibhekwa njengefanele amafilimu awugqinsi kuno-5 mils (125μm).
QAPHELA 1—Kuncike esivumelwaneni phakathi komthengi nomthengisi, Indlela Yokuhlola B ingasetshenziselwa amafilimu ashubile uma kusetshenziswa ukusikeka kwezikhala ezibanzi.
1.3 Lezi zindlela zokuhlola zisetshenziselwa ukuthola ukuthi ukunamathela kwentolo ku-substrate kusezakhini zofuzo.ralizinga elanele. Abahlukanisi phakathi kwamazinga aphezulu okunamathela okudingeka kuwo izindlela eziyinkimbinkimbi zokulinganisa.
QAPHELA 2—Kufanele kuqashelwe ukuthi umehluko ekubambeleleni kwendawo enamathelayo ungathinta imiphumela etholwe ngezingubo ezinokunamathela okungokwemvelo okufanayo.
1.4 Ezinhlelweni ze-multicoat ukuhluleka ukunamathela kungase kwenzeke phakathi kwamajazi ukuze ukunamathela kwesistimu yokugqoka ku-substrate kunganqunywa.
1.5 Amanani ashiwo kumayunithi e-SI kufanele athathwe njengezinga. Amanani anikezwe kubakaki awolwazi kuphela.
1.6 Leli zinga alihlosile ukubhekana nokukhathazeka kokuphepha, uma kukhona, okuhlobene nokusetshenziswa kwalo. Kuyisibopho somsebenzisi waleli zinga ukusungula izindlela zokuphepha ezifanele nezempilo futhi anqume ukusebenziseka kwemikhawulo yokulawula ngaphambi kokusetshenziswa.

2. Imibhalo ekhonjiwe

2.1 Amazinga e-ASTM:

• D 609 Ukuzijwayeza Ukulungiselela Amaphaneli Ensimbi Egoqelwe Ngamakhaza Okuhlola Upende, I-Varnish, I-Conversion Coatings, kanye Nemikhiqizo Yokunamathela Ehlobene2
• I-D 823 Imikhuba Yokukhiqiza Amafilimu Awugqinsi Okufanayo Kapende, Ivarnish, kanye Nemikhiqizo Ehlobene Kumaphaneli Okuhlola.
• I-D 1000 Indlela Yokuhlola Yamateyipu Anamathelayo Azwela Ukucindezela Asetshenziselwa Izicelo zikagesi neze-elekthronikhi.
• I-D 1730 Imikhuba Yokulungiselela I-Aluminium ne-Aluminium-Alloy Surfaces for Painting4

• Ukucaciswa kwe-D 3924 Kwendawo Ejwayelekile Yokupenda Nokuhlola I-Conditioning, I-Varnish, I-Lacquer, Nezinto Ezihlobene
• Indlela Yokuhlola ye-D 4060 Yokumelana Nokuhushulwa Kwezingubo Eziphilayo nge-Taber Abraser

3. Isifinyezo Sezindlela Zokuhlola

3.1 Indlela Yokuhlola A—Ukusikwa kwe-X kwenziwa ngefilimu kuya ku-substrate, itheyiphu ezwela ukucindezela isetshenziswa phezu kokusikwa bese iyasuswa, futhi ukunamathela kuhlolwa ngekhwalithi esikalini sika-0 kuya ku-5.
3.2 Indlela Yokuhlola B—Iphethini ye-lattice enokusikeka okuyisithupha noma okuyishumi nanye ohlangothini ngalunye lwenziwa kufilimu kuya ku-substrate, i-tape ezwela ukucindezela isetshenziswa phezu kwe-lattice bese ikhishwa, futhi ukunamathela kuhlolwa ngokuqhathanisa nezincazelo nemifanekiso.

4. Ukubaluleka Nokusetshenziswa

4.1 Uma i-coating izokwenza umsebenzi wayo wokuvikela noma wokuhlobisa i-substrate, kufanele ihambisane nayo impilo yesevisi elindelekile. Ngenxa yokuthi i-substrate kanye nokulungiswa kwayo kwendawo (noma ukungabi khona kwayo) kunomthelela omkhulu ekunamatheleni kwezigqoko, indlela yokuhlola ukunamathela kwe-coating kuma-substrates ahlukene noma ukwelashwa kwendawo, noma kwezingubo ezihlukene ku-substrate efanayo kanye nokwelashwa, oluwusizo olukhulu embonini.
4.2 Imikhawulo yazo zonke izindlela zokunamathela kanye nomkhawulo othile wale ndlela yokuhlola emazingeni aphansi okunamathela (bona 1.3) kufanele kuqashelwe ngaphambi kokuyisebenzisa. Ukunemba kwe-intra- kanye ne-inter-laboratory yale ndlela yokuhlola kufana nezinye izivivinyo ezamukelwa kabanzi zama-substrate amboziwe (ngokwesibonelo, Indlela Yokuhlola D 2370 kanye Nendlela Yokuhlola D 4060), kodwa lokhu ngokwengxenye kuwumphumela wokungabi nazwela kubo bonke. kodwa umehluko omkhulu wokunamathela. Isilinganiso esilinganiselwe sika-0 kuye ku-5 sikhethwe ngamabomu ukuze kugwenywe umbono ongamanga wokuzwela.
