Kev ruaj ntseg ntawm cov qauv steel feem ntau nyob ntawm qhov zoo thiab kev ua haujlwm ntawm bolts. Los ntawm qhov kev xav ntawm kev xaiv ntsia liaj qhov rooj, cov cuab yeej kho mob saum npoo ib txwm yog lub ntsiab lus kub. Thaum muas bolts, peb yuav pom tias qee qhov bolts muaj kev kho deg sib txawv. Vim li cas qhov no? Kab lus no yuav txheeb xyuas cov txheej txheem kev kho lub bolt saum npoo kom meej.
kub dip galvanizing
Kub-dip galvanizing thev naus laus zis yog ib txoj hauv kev kho cov ntsia hlau saum npoo, uas feem ntau muab kev tiv thaiv corrosion zoo thiab tiv thaiv xeb rau cov hlau matrix. Siv cov thev naus laus zis no, peb tuaj yeem npog cov ntsia liaj qhov rooj nrog ib txheej ntawm zinc txheej los tiv thaiv qhov ntsia hlau nto. Tsis tas li ntawd, cov zinc txheej kuj tseem tuaj yeem muab kev tiv thaiv kev txi rau cov bolts, uas yog, thaum corroding, lawv yuav raug corroded ua ntej, yog li ncua kev pab cuam lub neej ntawm bolts.
kub dip aluminized
Tsis zoo li kub-dip galvanizing tshuab, kub-dip aluminizing tshuab yog ib qho tshiab bolt nto kho txoj kev. Siv cov thev naus laus zis no, txheej txheej ntawm txhuas txheej tuaj yeem npog ntawm qhov ntsia liaj qhov rooj los tiv thaiv qhov ntsia hlau nto. Piv nrog rau kub-dip galvanizing tshuab, kub-dip aluminium plating tshuab muaj kev tiv thaiv corrosion zoo dua thiab tuaj yeem tiv taus qhov kub thiab txias ntau dua. Nyob rau tib lub sijhawm, aluminium plating tshuab kuj tuaj yeem muab qhov zoo dua hardness thiab lub zog rau steel bolts, yog li ua kom zoo thiab ua haujlwm ntawm cov bolts.
Dacromet
Dacromet yog zinc-aluminium composite khoom uas feem ntau coated rau saum npoo ntawm bolts. Dacromet txheej muaj cov khoom siv tiv thaiv corrosion zoo heev, uas tuaj yeem txuas ntxiv lub neej kev pab cuam ntawm bolts. Nyob rau tib lub sijhawm, nws muaj kev ua siab ntev rau qhov hnyav hnyav xws li kub kub thiab dej ntsev. Tsis tas li ntawd, Dacromet txheej kuj muaj qhov zoo ntawm cov adhesion siab heev, siab permeability, siab kev sib txhuam txo thiab tsis muaj kuab paug ib puag ncig.
Hluav taws xob galvanized
Electro-galvanizing thev naus laus zis tau siv dav hauv kev kho cov ntsia liaj qhov rooj vim nws tuaj yeem muab kev tiv thaiv zoo thiab tiv thaiv xeb rau steel bolts. Siv tshuab electro-galvanizing, peb tuaj yeem npog cov ntsia liaj qhov rooj nrog ib txheej zinc txheej. Cov txheej no tuaj yeem tiv thaiv corrosion los ntawm seawater, kua qaub los nag, huab cua muaj kuab paug thiab lwm yam, yog li ncua kev pab cuam lub neej ntawm lub ntsia liaj qhov rooj.
Cadmium plating
Cadmium plating yog ib txoj kev kho qhov muag ntsia hlau. Los ntawm npog lub ntsia liaj qhov rooj nrog ib zaj duab xis cadmium, qhov corrosion kuj ntawm lub ntsia liaj qhov rooj tuaj yeem txhim kho zoo heev. Txawm li cas los xij, vim yog cov nqi siab thiab kev ua qias tuaj ib puag ncig, galvanizing tau hloov los ntawm ntau tus phooj ywg ib puag ncig thiab pheej yig txoj kev kho deg, xws li kub-dip galvanizing thiab Dacromet.
PTFE
PTFE txheej yog ib qho tshwj xeeb polymer txheej. Los ntawm txheej nyias zaj duab xis rau saum npoo ntawm lub ntsia liaj qhov rooj, qhov saum npoo ntawm lub ntsia liaj qhov rooj tuaj yeem muaj kev tiv thaiv zoo heev thiab tiv thaiv corrosion. PTFE txheej muaj qhov sib txhuam coefficient tsawg heev thiab zoo heev los tiv thaiv hnav. Nws tuaj yeem tiv taus yaig los ntawm cov kua qaub nag, dej hiav txwv thiab lwm yam. Hauv kev kho cov ntsia hlau saum npoo, PTFE txheej feem ntau yog siv rau hauv cov xwm txheej tshwj xeeb, xws li cov khoom siv pneumatic uas yuav tsum tau muaj kev ua haujlwm siab thiab ua haujlwm siab corrosion.
Xylan
Xylan txheej yog kev kho qhov ntsia hlau uas muaj fluoropolymer. Tsis zoo li PTFE coatings, Xylan coatings feem ntau muaj ntau yam sib txawv lubricants thiab nkag mus rau cov neeg ua haujlwm, uas tuaj yeem muab kev tiv thaiv kom ntxaws ntxiv rau qhov ntsia hlau nto. Xylan txheej muaj qhov zoo ntawm lubricity zoo, hnav tsis kam, corrosion kuj thiab kev sib txhuam siab, thiab yog dav siv nyob rau hauv daim ntawv thov uas yuav tsum tau high precision thiab siab corrosion kuj.
Feem ntau hais lus, kev xaiv ntawm bolt nto kho tshuab yuav tsum tau ua raws li qhov xav tau tiag tiag thiab qhov xwm txheej siv. Los ntawm kev nkag siab txog cov txheej txheem kev kho deg sib txawv, peb tuaj yeem xaiv cov khoom kom haum rau peb cov kev xav tau, yog li ua kom muaj kev ruaj ntseg thiab ua haujlwm ntev ntawm cov qauv hlau.
