Kodi mudakumanapo ndi vutoli? Zitsulo zomwe zili mu nyali zomwe mudagula zimayamba kuwonetsa zizindikiro za dzimbiri pamwamba patatha nthawi yogwiritsa ntchito. Izi zikusonyeza kuti mtundu wa zinthu zoyatsira magetsi zotere suli bwino. Ngati mukufuna kudziwa chifukwa chake, lero tiwulula kuti zonsezi zikugwirizana kwambiri ndi "kuyesa kupopera mchere"!
Kodi mayeso a Salt Spray ndi chiyani?
Mayeso a Salt Spray ndi mayeso oteteza chilengedwe omwe amagwiritsidwa ntchito poyesa kukana dzimbiri kwa zinthu kapena zinthu zachitsulo. Amayerekezera malo otetezera mchere kuti awone kulimba kwa zinthuzo pansi pa mikhalidwe yotereyi ndikuwunika momwe zimagwirira ntchito komanso moyo wawo wautali m'malo owononga.
Kugawa Mayeso:
1. Utsi Wothira Mchere Wosalowerera (NSS)
Neutral Salt Spray Test ndiyo njira yoyamba komanso yogwiritsidwa ntchito kwambiri yoyesera dzimbiri mwachangu. Nthawi zambiri, imagwiritsa ntchito yankho la madzi amchere a sodium chloride la 5% yokhala ndi pH yosinthidwa kukhala neutral range (6.5-7.2) kuti igwiritsidwe ntchito popopera. Kutentha kwa mayeso kumakhalabe pa 35°C, ndipo kuchuluka kwa mchere womwe umayikidwa m'nthaka kuyenera kukhala pakati pa 1-3 ml/80cm²·h, nthawi zambiri 1-2 ml/80cm²·h.
2. Acetic Acid Salt Spray (AASS)
Mayeso a Acetic Acid Salt Spray adapangidwa kuchokera ku Neutral Salt Spray Test. Amaphatikizapo kuwonjezera glacial acetic acid ku yankho la 5% sodium chloride, kutsitsa pH kufika pafupifupi 3, kupanga yankho kukhala acidic, ndipo motero kusintha chifunga cha mchere kuchoka ku neutral kupita ku acidic. Kuchuluka kwa dzimbiri kwake kumakhala kofulumira katatu kuposa mayeso a NSS.
3. Mchere Wothira Mchere Wowonjezera wa Copper Accelerated Acetic Acid (CASS)
Mayeso a Copper Accelerated Acetic Acid Salt Spray ndi mayeso atsopano opangidwa ndi kupopera kwa mchere mwachangu kunja kwa dziko. Kutentha kwa mayesowa ndi 50°C, ndipo mchere wochepa wa mkuwa (copper chloride) umawonjezeredwa ku yankho la mchere, zomwe zimapangitsa kuti dzimbiri liziyenda mofulumira kwambiri. Kuchuluka kwa dzimbiri kwake kumakhala kofulumira kasanu ndi kawiri kuposa mayeso a NSS.
4. Kupopera Mchere Wosinthana (ASS)
Mayeso Othira Mchere Wosinthana ndi mayeso othira mchere omwe amaphatikiza kuthira mchere kosalekeza komanso chinyezi chosalekeza. Amagwiritsidwa ntchito makamaka pazinthu zamakina onse, zomwe zimapangitsa kuti mchere usawonongeke osati pamwamba pa chinthucho chokha komanso mkati mwake kudzera mu chinyezi. Zinthuzo zimadutsa munjira zosiyanasiyana pakati pa chifunga cha mchere ndi chinyezi, kuwunika kusintha kwa magwiridwe antchito amagetsi ndi makina azinthu zamakina onse.
Kodi zinthu zowunikira za Liper zimayesedwanso ndi mankhwala opopera mchere?
Yankho ndi Inde! Zipangizo zachitsulo za Liper zopangira nyali ndi zowunikira zimapangidwa motsatira miyezo yapadziko lonse lapansi. Kutengera muyezo wa IEC60068-2-52, amayesedwa mwachangu za dzimbiri zomwe zimaphatikizapo kuyesa kosalekeza kwa maola 12 (kuti aphimbe chitsulo). Pambuyo pa mayesowo, zipangizo zathu zachitsulo siziyenera kuwonetsa zizindikiro za okosijeni kapena dzimbiri. Pokhapokha zinthu zowunikira za Liper zitha kuyesedwa ndikuyenerera.
Tikukhulupirira kuti nkhaniyi ithandiza makasitomala athu kumvetsetsa kufunika koyesa kupopera mchere. Posankha zinthu zowunikira, ndikofunikira kusankha njira zabwino kwambiri. Ku Liper, zinthu zathu zimayesedwa mwamphamvu, kuphatikizapo mayeso opopera mchere, mayeso a moyo, mayeso osalowa madzi, ndi mayeso ophatikiza ma sphere, ndi zina zotero.
Kuwunika bwino kwa khalidwe kumeneku kumaonetsetsa kuti makasitomala a Liper amalandira zinthu zowunikira zapamwamba komanso zodalirika, motero kumawonjezera moyo wabwino wa makasitomala athu komanso kukhutitsidwa kwathunthu.
Monga wopanga magetsi waluso, Liper ndi waluso kwambiri posankha zinthu, zomwe zimakupatsani mwayi wosankha ndikugwiritsa ntchito zinthu zathu molimba mtima.
