zinc a ɛyɛ tuntum a wɔde hyɛ mu . wɔde di dwuma wɔ nneɛma ahorow mu. Zinc layer tuntum no ma corrosion resistance nanso ɛyɛ ɔkwan a ɛyɛ mmerɛw so. Nea ɛka ho no, nea ɛyɛ tuntum no yɛ kɛse sen oxide tuntum a wɔtaa de wie no. Wɔn a wɔde di dwuma a wohia nea aba so ne corrosion ahobammɔ a ɛyɛ mmerɛw no betumi apaw zinc bolt tuntum.

 

Zinc-plated bolts no wɔ decorative black finish, na ɛma ɛyɛ fɛ bere a wɔawie adwuma no.

 

Zinc bolts tuntum no ye ma mmeae a ɔhyew a ɛkɔ soro anaa ɔhyew a ano yɛ den wom. Ebia corrosion ne tebea a ɛyɛ hu sen biara ma nnwuma dodow no ara. Sɛ obi wɔ zinc a ɛyɛ tuntum a, obi betumi ahwɛ kwan sɛ ahobammɔ a ɛma abotɔyam wɔ nsɛe ho.

 

Zinc plating a ɛyɛ tuntum no hwehwɛ sɛ wɔde zinc di dwuma wɔ electrolytic mu wɔ dade a wɔpɛ no so. Afei, nea ɔyɛ no de bolt no hyɛ zinc plating bath mu na ɔde anyinam ahoɔden di dwuma.

 

Zinc tuntum a wɔde kata so no yɛ adwuma sɛ kyɛm anaa akwanside a ɛbɛma wɔabɔ bolt no ho ban afi nneɛma ahorow nyinaa a asɛe ho, te sɛ nea asɛe ne nea ɛbɛtetew ne nea asɛe, na ɛma ne nyinaa yɛ kɛse.

 

Black zinc bolts ma wonya mfaso pii, na ɛma ɛyɛ nea agye din wɔ nnwuma ahorow mu. Eyinom yɛ mmerɛw sɛ wode bedi dwuma na enni build-akɔ soro nso.

 

Sɛ wode zinc bolts tuntum di dwuma a, wubetumi ahwɛ kwan sɛ wɔbɛbɔ wo ho ban afi nsɛe ne abɔnten so beac a ɛyɛ fɛ ho.
