Udonga olomileyo lwezikhonkwane zokuzicofa

I-Phosphated dry wall screws yeyona nto isisiseko somgca wemveliso, ngelixa i-zinc eluhlaza okwesibhakabhaka kunye ne-zinc eyomileyo ye-screws yodonga izongezelelo, kunye nobubanzi besicelo kunye nexabiso lokuthenga ngokusisiseko. Ukwahluka kancinci kukuba i-phosphating emnyama inomlinganiselo othile we-lubricity, kwaye isantya sokuhlasela (isantya sokungena kwi-thickness ecacisiweyo ye-steel plate, eyisalathisi sokuhlola umgangatho) singcono kancinci; I-zinc eluhlaza okwesibhakabhaka nemhlophe inefuthe elingcono lokuthintela umhlwa, kwaye umbala wendalo wemveliso ulula, okwenza kube lula ukucima emva kokuhombisa.

Phantse akukho mahluko kumandla okuthintela umhlwa phakathi kwe-zinc emhlophe eluhlaza kunye ne-zinc etyheli, kuphela ngenxa yomahluko kwimikhwa yokusetyenziswa okanye ukhetho lomsebenzisi.

Umsonto womsonto omnye orhabaxa izinyo elomileyo lodonga jiko lubanzi, kwaye isantya sokuhlasela esihambelanayo sikwakhawuleza. Kwangaxeshanye, kuba angonakalisi isakhiwo sezinto zokhuni ngokwazo emva kokungena emthini, ifaneleke ngakumbi ukufakelwa kwe-keel yomthi kunezikhonkwane zodonga ezizinyo eziphindwe kabini.

Isetyenziselwa ukudibanisa phakathi kwebhodi ye-gypsum kunye ne-metal keel enobunzima obungadlulanga i-2.3mm, ekhoyo kwi-phosphating emnyama kunye nokukhethwa kwe-yellow zinc. Umda wesicelo kunye nexabiso lokuthenga zombini ziyafana. Kwaye i-zinc ephuzi inefuthe elingcono lokuthintela umhlwa, kwaye umbala wendalo wemveliso ulula, okungekho lula ukucima emva kokuhlobisa.
