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, i-industry yelizwe lokhuselo, njl. Njengeyona ndlela ixhaphakileyo yonyango lwe-pulley surface ngoku, iyinto ehambelanayo nendalo kwaye ineempawu ezilandelayo xa kuthelekiswa ne ukugalela ngokwesintu:

(1) Ungasebenzisi i-cyanide enetyhefu, ngoko ke amanzi amdaka avelisiweyo anokucocwa lula.

(2) I-coating ine-crystallization ecocekileyo, i-gloss enhle, kunye nokukwazi ukusabalalisa kunye nokukwazi ukucwenga okunzulu kusondele kwisisombululo 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 nezibonelelo.Umhlobiso weChromium usebenzisa i-nickel, iteknoloji ye-nickel chromium ukuqinisekisa umgangatho wemveliso. Umphezulu wesilivere umhlophe, 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 uvulelwe ukwenza ipuli yokugquma irabha. Xa kuthelekiswa ne-pulley eqhelekileyo, i-pulley yokugubungela i-rubber ineempawu zokuba yi-elastic, i-wear resistance, i-asidi kunye nokumelana ne-alkali, ukumelana ne-oyile (NBR), ukumelana nobushushu kunye nobungqina bokugqwala njl. Kusetyenziswa imathiriyeli ekrwada kunye nezinto ezincamathelayo ezivela kwamanye amazwe. 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 nomhlwa, lusetyenziswa kumatshini wokubumba, ukungunda kweplastiki, iivalvu ezinganyangekiyo, ukuprinta, ilaphu kunye nokwenza iphepha. ukusetyenzwa kunye nezixhobo zokulinganisa, umphezulu wesilivere omhlophe.
