Kupisa simbi inonzi "hot dip galvanizing" inzira inoshandiswa zvakanyanya kudzivirira simbi kubva mukuora. Inonyudza simbi mubhavhu rezinc yakanyungudutswa, zvichiita kuti ive jira rinodzivirira pamusoro pesimbi. Maitiro aya anowanzonzi "ahari ye zincnekuti inosanganisira kunyudza simbi muhari ye zinc yakanyungudutswa. Simbi inobuda mu galvanized inozivikanwa nekusimba kwayo uye kuramba ngura, zvichiita kuti ive sarudzo yakakurumbira mumabasa akasiyana-siyana, kubva pakuvaka kusvika pakugadzira mota.
Mubvunzo unowanzo bvunzwa unobatanidzwa nekunyudza nekupisaNyaya ndeyekuti zinc coating ichaparadza simbi yakarungwa here nekufamba kwenguva. Kuti tigadzirise dambudziko iri, zvakakosha kunzwisisa hunhu hwezinc uye kuti dzinoshanda sei nesimbi.
Zinc isimbi ine simba guru, iyo, kana yaiswa pasimbi kuburikidza nekunyudza nekupisa, inoumba nhevedzano yezvikamu zve zinc-iron alloy pamusoro pesimbi. Zvikamu izvi zvinopa chipingamupinyi chaicho, zvichidzivirira simbi iri pasi kubva kuzvinhu zvinoparadza zvakaita sehunyoro neokisijeni. Pamusoro pezvo, chifukidziro che zinc chinoshanda seanode yechibayiro, zvinoreva kuti kana chifukidziro chikakuvara, chifukidziro che zinc chichaora kupfuura simbi, zvichidzivirira simbi kubva mukuora zvakanyanya.
Kazhinji, zinc coating pasimbi yakarungwa inopa dziviriro yenguva refu yengura kunyangwe munzvimbo dzakaoma. Zvisinei, mune dzimwe nguva, galvanized coating inogona kukanganiswa, zvichikonzera ngura inogona kuitika yesimbi iri pasi. Chimwe chezviitiko zvakadaro kusangana nenzvimbo dzine acidic kana alkaline, izvo zvinokurumidzisa ngura yezinc coating uye zvinokanganisa hunhu hwayo hwekudzivirira. Pamusoro pezvo, kugara kwenguva refu uchipisa zvakanyanya kunogona kukonzera kuti zinc coating iparare, zvichikonzera ngura yesimbi.
Zvakakosha kucherechedza kuti kana zinc coating iri pamusorosimbi yakarukwainoshanda zvikuru pakudzivirira simbi kubva mukuora, haina kudzivirirwa pakukuvadzwa. Kukuvadzwa kwemuchina, senge kukwenya kana maburi, kunogona kukanganisa kusimba kwe zinc coating uye kuisa simbi iri pasi panjodzi yekuora. Nokudaro, kubata nekugadzirisa zvakanaka zvigadzirwa zvesimbi zvakarukwa kwakakosha kuti ive nechokwadi chekuti zvinoramba zvichidzivirira ngura kwenguva refu.
Mukupedzisa,kupisa dip galvanizing, inozivikanwawo sehari ye zinc, inzira inoshanda yekudzivirira simbi kubva mukuora.Kugadzira simbiinoumba jira rekudzivirira rakasimba pamusoro pesimbi, zvichipa kudzivirira ngura kwenguva refu munzvimbo zhinji. Kunyange zvazvo machira esimbi anogona kukuvara pasi pemamwe mamiriro ezvinhu, kugadzirisa zvakanaka uye kubata zvigadzirwa zvesimbi zvesimbi zvinobatsira kuve nechokwadi chekuti zvinoramba zvichidzivirira ngura. Kazhinji, simbi yesimbi inoramba iri sarudzo yakavimbika uye inogara kwenguva refu yekushandiswa kwakasiyana-siyana nekuda kwehunhu hwekudzivirira hwezinc coating.
