Mu kugabanya urumuri rusanzwe, hamwe no kureba amaso.Ijwi ryibanze rya zinc chromate itwikiriye igomba kuba ifu yumukara, irashobora kandi kuboneka muguhindura andi mabara, nkumukara.Zinc chromate itwikiriye igomba guhoraho, itagira ikidodo, ibibyimba, ibishishwa, gucamo, gutobora, gushiramo hamwe nizindi nenge.Igipfundikizo kigomba kuba kimwe, ntakintu kigaragara kiboneka cyane.Igifuniko ntigomba guhinduka ibara, ariko cyemerera utudomo duto twumuhondo.
Icya kabiri, umubare wikigereranyo hamwe nuburinganire bwikizamini:
Ingano isanzwe yubunini bwububiko cyangwa igipande cyamanota atandukanye igabanijwemo ibyiciro bine, uburyo bubiri bushobora gukoreshwa mugushakisha:
1. chromium yatwikiriye.Icyitegererezo cyakuweho, cyogejwe neza namazi ako kanya akimara gukama, igipfundikizo kirashonga, nkuko byavuzwe na misa yikizamini nyuma ya W2 (mg).Kandi ubare ingano yubuso bwubuso bwa ?? urupapuro rwakazi S (dm2), ukurikije formula ikurikira kugirango ubare umubare wububiko bwa W (mg / dm2):
W = (W1-W2) / S.
2, uburyo bwa microscope: kanda GB / T6462 ibisabwa, ukoresheje microscopi optique yakoreshejwe kugirango umenye ubunini bwa coating.
Icya gatatu, ikizamini cyingufu zifatika:
Ukoresheje uburyo bwo gupima kaseti, imbaraga zifatika zerekana zinc chromate coating na substrate, hamwe na test ya kaseti ukurikije GB / T5270-1985 ibisabwa mubice 1.4.Nyuma yikizamini cyibizamini ntigishobora gukurwaho hejuru yikibiriti, cyangwa gufungura amaherezo, ariko kwemerera ibara rya kaseti ifata amabara hamwe na zinc, ibinyampeke bya aluminium.
Ikizamini cyo kurwanya amazi: Icyitegererezo cyinjijwe mumazi ya deionioni 40 ℃ ± 1 ℃, kwibiza mu buryo bwa 240h, nyuma yo gukuramo icyitegererezo no gukama ku bushyuhe bwicyumba, hanyuma igeragezwa ryingufu zifatika, ibisubizo byikizamini bigomba kuba byujuje ibisabwa imbaraga zifatika. ikizamini.Ikizamini cyingufu za Adhesion kigomba gukorwa mugihe cya 2h cyakuwe kumwanya wamazi yimana.Nyuma yikizamini cyo kurwanya amazi, igifuniko ntigishobora guhindagurika cyangwa gufungura kumpera ya substrate.
