Njira zochizira pamwamba zomwe zimagwiritsidwa ntchito kwambiri pamipanda ya udzu

1. Zopaka malata

Zinc plating amagawidwa mu electro-galvanized (ozizira plating) ndi otentha-kuviika galvanizing. The wandiweyani zofunika nthaka carbonate filimu anapanga pamwamba nthaka ntchito kukwaniritsa cholinga odana ndi dzimbiri, odana ndi kukokoloka ndi maonekedwe okongola. Electroplating zinki amagwiritsa ntchito mfundo ya electrolysis kulola ayoni zinc kumamatira pamwamba pa zitsulo mauna kupanga zokutira. Cyanide mu galvanizing electrolyte ndi poizoni kwambiri. Chikhalidwe cha electroplating ndi chakuti nthaka wosanjikiza ndi yabwino komanso yaying'ono, ndipo gloss ndi yolimba. Kutentha kwa dip galvanizing ndikuyika zinthuzo kuti zikutidwe muzitsulo za zinki zopaka kutentha kwambiri pambuyo pa anti-oxidation, annealing ndi mankhwala ena. Ubwino wa galvanizing wotentha ndikuti wosanjikiza wa zinki waphimbidwa mokwanira, kulimba kwake kumakhala kolimba, ndipo moyo wautumiki wa zaka 20-50 ukhoza kusungidwa. Mtengo wokwera kwambiri wamagetsi opangira magetsi.

2. Kuviika

Kuyika kwa pulasitiki nthawi zambiri kumatenthetsa mbali zomwe zimayikidwa kuti zisungunuke ufa wa pulasitiki pamwamba pazitsulo za mauna a udzu. Kutentha nthawi ndi kutentha kudzakhudza makulidwe a pulasitiki wosanjikiza. Kuyika kwa pulasitiki kumatha kukulitsa kukana kwamadzi, dzimbiri komanso kukokoloka kwa chinthucho. Mtunduwu umapangitsa kuti mankhwalawa akhale okongola komanso okongola kwambiri.

3. Utsi pulasitiki

Kupopera mbewu mankhwalawa kumagwiritsa ntchito mfundo ya magetsi osasunthika kupanga pulasitiki ufa adsorb pa mankhwala, ndiyeno kutentha ndi kulimbitsa ndondomeko kukwaniritsa cholinga odana kukokoloka kwa ❖ kuyanika mankhwala. Kupopera mbewu mankhwalawa kumagwiritsidwa ntchito muzinthu zosakhalitsa. Pulasitiki wosanjikiza ndi woonda kuposa ndondomeko yoviika. Ubwino wake ndi wotsika mtengo komanso wachangu.

4. Anti- dzimbiri utoto

Utoto woletsa dzimbiri ndi wosavuta kugwiritsa ntchito, wotsika mtengo, umagwira ntchito mwamphamvu, komanso kusachita bwino kwa dzimbiri komanso kudana ndi dzimbiri.

5. Chitsulo chamkuwa

Chitsulo chamkuwa nthawi zambiri chimapangidwa ndi electroplating ndi kuponyera mosalekeza. Yoyamba imagwiritsa ntchito mfundo ya electrolysis. Udzu waudzu ndi wotsika mtengo komanso wokutira ndi woonda. Njira yoponyera mosalekeza imapangitsa kuti mkuwa ndi zitsulo zotsekera zigwirizane bwino popanda kulumikizidwa.
