Unyango lomphezulu wepuli

Iipuli yokuhambisaumphezulu unokunyangwa ngeendlela ezahlukeneyo ngokuhambelana neemeko ezingqongileyo kunye neziganeko ezithile.Iindlela zonyango zohlulwe ngokwezi ntlobo zilandelayo:

1. Gukulungiswa

I-galvanization ifanelekile kwizixhobo zoshishino ezisetyenziselwa imboni yokukhanya, i-instrumentation, imboni ye-electromechanical, oomatshini bezolimo, imboni yezokhuselo yelizwe, njl. Njengeyona ndlela ixhaphakileyo yonyango lwe-pulley surface okwangoku, iyinto ehambelanayo nendalo kwaye ineempawu ezilandelayo xa kuthelekiswa ne ukugalela ngokwesintu:

(1) Ungayisebenzisi icyanide enetyhefu, ngoko ke amanzi amdaka avelisiweyo anokucocwa lula.

(2) I-coating ine-crystallization ecocekileyo, i-gloss enhle, kunye nokukwazi ukusabalalisa kunye nokukwazi ukubethelwa okunzulu kusondele kwezo zesisombululo se-cyanide plating, esilungele ukubethelwa kwe-electroplating yamalungu anemilo enzima.

(3) Isisombululo seplating esizinzileyo kunye nokusebenza kakuhle

(4) Akukho mhlwa kwisixhobo

(5) Iindleko eziphantsi

 

2. IziKronikei-meplate

I-chromium yokuhlobisa isetyenziselwa kakhulu kwiimoto, iibhayisikili, i-hardware yendlu, izixhobo zasekhaya, izixhobo zokutshintsha, iinxalenye zomatshini kunye nezinye izixhobo kunye nezixhobo.Umhlobiso weChromium usebenzisa i-nickel, iteknoloji ye-nickel chromium ukuqinisekisa umgangatho wemveliso.Umphezulu wesilivere omhlophe, uhonjiswe nge-chrome ngokuxhathisa okuqinileyo kwe-corrosion kunye nesiphumo esihle sokuhombisa, kunye ne-coefficient ephezulu ebonakalisayo.

3. Isigqubuthelo serabha

Umbhobho wesinyithi wentsimbi uqatywe ngerabha, emva koko uvulwe ukuze wenze ipuli yokugquma irabha.Xa kuthelekiswa ne-pulley eqhelekileyo, i-pulley yokugubungela i-rubber ineempawu zokuba yi-elastic, ukumelana nokugqoka, ukuxhathisa kwe-asidi kunye ne-alkali, ukumelana ne-oyile (NBR), ukumelana nobushushu kunye nobungqina bokugqwala njl.Kusetyenziswa imathiriyeli ekrwada ephuma kumazwe angaphandle kunye nezinto zokuncamathelisa.Irabha yendalo kunye ne-NBR zisetyenziswa ngokuqhelekileyo.Umnyama, oluhlaza kunye nokukhanya okungwevu yimibala ecetyiswayo.

4. Ukufakwa kwe-chrome enzima

I-chromium enzima ikwabizwa ngokuba yichromium engagugiyo, unyango lunokonyusa ubulukhuni bomphezulu wepuli, luphucule ukumelana nokunxiba, ubushushu kunye nokumelana nokugqwala, kusetyenziselwa ukubumba oomatshini, ukungunda kweplastiki, iivalvu ezinganyangekiyo, ukuprinta, ilaphu kunye nokwenza iphepha. ukusetyenzwa kunye nezixhobo zokulinganisa, umphezulu wesilivere omhlophe.
