Wace hanya za a iya amfani da ita wajen rigakafin lalata?

Gabaɗaya, hanyoyin rigakafin lalata za a iya raba su zuwa manyan rukuni biyu:

1.Madaidaicin zaɓi na kayan jure lalata da sauran matakan rigakafi

2. Zabar aiki mai ma'ana da tsarin kayan aiki

Bin ƙa'idodin tsari a cikin samar da sinadarai na iya kawar da abubuwan lalata da ba dole ba. Duk da haka, ko da an yi amfani da kayan aiki masu inganci masu inganci, hanyoyin da ba su dace ba na iya haifar da lalata mai tsanani.

1. Inorganic Corrosion Inhibitors;

Yawanci, ƙara ƙaramin adadin masu hana lalatawa zuwa yanayi mai lalacewa na iya rage lalata ƙarfe da muhimmanci. Wadannan masu hana su an hada su cikin nau'ikan uku: Inorganic, Organic, da kuma tururi-da yawa, kowannensu tare da na daban inji.

• Masu hana Anodic (sauƙa da tsarin anodic):

Waɗannan sun haɗa da oxidizers (chromates, nitrites, iron ions, da dai sauransu) waɗanda ke haɓaka haɓakar anodic ko abubuwan yin fim na anodic (alkalis, phosphates, silicates, benzoates, da sauransu) waɗanda ke samar da fina-finai masu kariya a saman anode. Suna da farko mayar da martani a cikin anodic yankin, inganta anodic polarization. Gabaɗaya, masu hana anodic suna samar da fim mai kariya akan farfajiyar anode, wanda yake da tasiri sosai amma yana ɗaukar wasu haɗari-rashin isasshen adadin zai iya haifar da ɗaukar hoto mara cika, yana barin ƙananan wuraren da ba a bayyana ba na ƙarfe tare da babban adadin anodic na yanzu, yana sa lalata lalata ta fi dacewa.

• Masu hana Kathodic (aiki akan halayen cathodic):

Misalai sun haɗa da alli, zinc, magnesium, jan ƙarfe, da ions manganese, waɗanda ke amsawa da ions hydroxide da aka samar a cathode don samar da hydroxides marasa narkewa. Wadannan suna samar da fina-finai masu kauri akan farfajiyar cathode, suna toshe yaduwar iskar oxygen da haɓaka polarization.

• Masu hanawa masu gauraya (sun hana halayen anodic da cathodic):

Waɗannan suna buƙatar ƙayyadaddun gwaji na mafi kyawun sashi.

2.Organic Corrosion Inhibitors

Masu hana kwayoyin halitta suna aiki ta hanyar adsorption, suna samar da fim ɗin da ba a iya gani, mai kauri a kan saman ƙarfe wanda a lokaci guda yana hana halayen anodic da cathodic (ko da yake yana da tasiri daban-daban). Masu hana kwayoyin halitta na yau da kullun sun haɗa da nitrogen-, sulfur-, oxygen-, da mahadi masu ɗauke da phosphorus. Hanyoyin tallan su sun dogara da tsarin kwayoyin halitta kuma ana iya rarraba su kamar:

· Electrostatic adsorption

· Adadin sinadarai

π-bond (delocalized electron) adsorption

Ana amfani da masu hana ƙwayoyin cuta da yawa kuma suna haɓaka cikin sauri, amma kuma suna da illa, kamar:

· Gurɓataccen samfur (musamman a aikace-aikacen da ke da alaƙa da abinci) - yayin da yake da fa'ida a cikin pro ɗaya

matakin raguwa, za su iya zama cutarwa a wani.

Hana halayen da ake so (misali, rage saurin cire fim yayin tsinkar acid).

3. Masu hana lalata-lokacin tururi;

Waɗannan abubuwa ne masu canzawa sosai waɗanda ke ɗauke da ƙungiyoyi masu hana lalata, da farko ana amfani da su don kare sassan ƙarfe yayin ajiya da jigilar kaya (sau da yawa a cikin tsari mai ƙarfi). Tushen su yana sakin ƙungiyoyi masu hanawa a cikin danshi na yanayi, wanda sannan ya shiga saman saman ƙarfe don rage lalata.

Bugu da ƙari, su masu hana hanawa ne, ma'ana kariya daga saman ƙarfe ba ya buƙatar cire tsatsa a gabani.
