Nsɛm a wɔafa aka ama wo retrofit batch no ka sɛ nkyene a wɔde petepete sɔhwɛ: nnɔnhwerew 240, ASTM B117.

Ruihua Hardware de po so hyɛn gyina saa check anum koro yi ara so, na ɛno nti na wɔkenkan te sɛ nhwehwɛmu nhyehyɛe a wɔakyerɛw afi benkyi no fã foforo no.
Nea edi kan no, hu nea kabinet no yɛ. ASTM B117 petepete sodium chloride sum ɔha biara mu nkyem 5 wɔ 35 °C, bere nyinaa, wɔ ɔfã bi a ɛsensɛn so.

Ɛkyerɛ wo sɛnea ade biako a wɔde kata so yɛ n’ade tia foforo wɔ ayayade a ɛte saa ara a ennyae mu. Ɛnkyerɛ wo date.
Enti fa gyinabea no ntɛm. Nsɛm biara a wɔafa aka a ɛdannan nnɔnhwerew 240 kɔ 'mfe a ɛwɔ afuw mu' mu no retɔn wo nɔma a sɔhwɛ no ntumi mma. Washdown chemistry, kwan so nkyene, abrasion ne UV nyinaa bue ntua akwan a cabinet no nhu da. Gye nnɔnhwerew 240 tom sɛ aboboano a wokura suppliers to, batch against batch ne coating against coating. Pow dɔnhwerew dodow no nkyerɛase biara a ɛkɔ kalenda mu. Saa gyinabea no nkutoo kum akyinnyegye dodow no ara a wɔde kata ade so ansa na afi ase.
Kenkan asɛm a wɔka wɔ asɛm a wɔafa aka no so no asɛmfua biara. Ɔfrɛ a wotumi di ho adanse no kura nneɛma anan: edin a wɔahyɛ da ayɛ (ASTM B117 anaa ISO 9227 NSS), dɔnhwerew dodow, pass criterion, ne coating ne ne kɛse. 'Zinc-nickel 8–12 μm, nkannare kɔkɔɔ biara nni hɔ wɔ 240 h akyi wɔ ASTM B117 biara mu' yɛ asɛm a wɔka. 'Salt spray tested' yɛ asɛmti, na wɔrentumi nhwɛ asɛm bi mu, nsan nyɛ bio, anaasɛ wɔmfa nnye akyinnye bere a nkwaa bi su wɔ ɔsram du-baako mu.

Dɔnhwerew dodow no nkyerɛ hwee kosi sɛ wubehu nea wobu no sɛ huammɔdi. White rust yɛ zinc corrosion nhwiren a ɛwɔ soro. Ɛte sɛ nea enye na ɛnyɛ bɔne biara; ɛyɛ ɔfã a edi kan a wɔhwɛ kwan wɔ zinc nhyehyɛe biara so. Red rust yɛ base steel corroding, na ɛhɔ na coating adi nkogu ankasa.
Enti ɛsɛ sɛ gyinapɛn a wugye tom no gyina red-rust so bere a fitting no yɛ adwuma wɔ abɔnten no. Sɛ wopɛ zinc-nickel spec a, line no yɛ 'no red rust wɔ nnɔnhwerew 240 mu'. Nhwiren a ɛyɛ hare a ɛwɔ soro wɔ dɔnhwerew 240 mu wɔ ɔfã a wɔayɛ no pasivated so no nyɛ huammɔdi a ɛba ara kwa. Wɔ standard zinc plating, akontaabu no yɛ soronko na ɛyɛ nokware: zinc nhyehyɛe a ɛwɔ 5–8 μm range no taa kura fitaa rust off bɛyɛ nnɔnhwerew 96, na kɔkɔɔ rust du hɔ yiye ansa na 240. Ɛno yɛ ade a ɛfata ma nhyehyɛe no, ɛnyɛ nea wobegyina so apow — ɛyɛ nea wogyina so ma ɔfã no si dan mu. Failure mode a woma ho kwan no na esi atemmu no ho gyinae, enti kyerɛw criterion no ansa na batch no akɔ, na ɛnyɛ akyi.
Nnɔnhwerew a enni thickness yɛ fã spec. Deposits a 8–12 μm zinc-nickel soa nnɔnhwerew 240 wɔ kabinet no mu; deposits of 5–8 μm zinc carry roughly 96. Amanneɛbɔ bi a ɛkyerɛ sɛ nnɔnhwerew 240 wɔ 3 μm deposit so no rekyerɛkyerɛ batch foforo bi, anaasɛ supplier foforo bi mu.
