Lub luag haujlwm ntawm phosphating kev kho mob ntawm kev sib txhuam kev sib txhuam ntawm elastic clips
Yog vim li cas phosphating yog siv rau elastic clips es tsis txhob ncaj galvanizing?
Ncaj nraim galvanized clips muaj ntau qhov chaw du nrog kev sib txhuam loj coefficient hloov pauv, ua rau nws nyuaj los xyuas kom meej clamping quab yuam thaum sib dhos. Phosphating ua rau micro- ntxhib phosphate zaj duab xis rau ntawm qhov chaw clip, stabilizing qhov kev sib txhuam coefficient nyob rau hauv qhov tsim ntau yam thiab ua kom muaj tseeb torque hloov dua siab tshiab. Tsis tas li ntawd, phosphating zaj duab xis ua lub hauv paus rau galvanizing, txhim kho qhov adhesion ntawm zinc txheej thiab clip matrix los tiv thaiv tev. Rau cov uas tsis yog-galvanized clips, phosphating muab luv luv - tiv thaiv corrosion rau cia thiab kev tsim kho.
Qhov kev sib txhuam coefficient ruaj khov ntawm phosphating zaj duab xis cuam tshuam li cas clip clamping quab yuam?
Clamping quab yuam yog txiav txim los ntawm kev sib dhos torque thiab kev sib txhuam coefficient, nrog cov qauv: clamping quab yuam yog proportional rau torque thiab inversely proportional rau kev sib txhuam coefficient. phosphating zaj duab xis tswj cov kev sib txhuam coefficient dispersion ntawm tib batch ntawm clips nyob rau hauv 5%, kom ntseeg tau raws li clamping quab yuam nyob rau hauv tib torque. Kev sib txhuam tsis ruaj khov ua rau lub zog clamping tsis txaus (ua rau kev tsheb ciav hlau loosening) los yog lub zog clamping ntau dhau (ua rau cov yas deformation ntawm clips). Kev sib txhuam ruaj khov yog lub hauv paus tseem ceeb rau kev ua haujlwm ruaj khov ntawm qhov system.
Cov xwm txheej twg tsim nyog rau cov yeeb yaj kiab phosphating sib txawv (xws li zinc-raws li, manganese-raws li)?
Zinc-raws li phosphating films yog mos nrog cov kev sib txhuam me me, haum rau cov clips ntawm cov kab ceev zoo tib yam, muaj cov nqi qis thiab sib dhos yooj yim. Manganese-raws li phosphating films yog ib qho nyuaj thiab hnav-resistant nrog kev sib txhuam ruaj khov coefficients, zoo tagnrho rau siab - lub zog clips ntawm siab- nrawm thiab hnyav- cov kab, nrog rau ntev - kev sib txhuam hnav hauv qab vibration. Rau kev hloov- cov clips tshwj xeeb, hloov manganese{10}}raws li phosphating zaj duab xis yog siv los sib npaug kev sib txhuam ruaj khov thiab hnav tsis kam vim kev nyuaj siab thiab kev sib txhuam ntau zaus.
Kev sib dhos thiab kev pabcuam teeb meem dab tsi tshwm sim los ntawm kev tsis tsim nyog phosphating?
Ib yam nkaus thiab - nyias lossis phosphating zaj duab xis ua rau muaj kev sib txhuam coefficient txawv txav, yuav tsum muaj lub zog siab dua kom ua tiav qhov tsim clamping quab yuam thiab yooj yim ua rau bolt overload. Ib zaj duab xis tuab dhau los yog tsis sib xws txo cov kev sib txhuam coefficient, ua rau tsis txaus clamping quab yuam thiab clip loosening hauv tsheb ciav hlau kev co. Tsis tas li ntawd, tsis tsim nyog phosphating films nqus dej noo thiab xeb yooj yim, txo cov corrosion kuj thiab cuam tshuam rau tom qab galvanizing zoo, ua rau zinc txheej blistering thiab tev.
Yuav txiav txim sai npaum li cas rau kev tsim nyog ntawm clip phosphating ntawm -site?
Cov phosphated clips uas tsim nyog muaj ib lub teeb grey-dub lossis tsaus grey nto, tsis muaj hlau puag, xeb dawb, lossis pom tseeb dai tshauv. Kov lub ntsej muag zoo nkaus li du yam tsis muaj hmoov poob, thiab tsis muaj hlau luster tshwm sim tom qab siv zog so. Thaum lub sij hawm sib dhos, ua raws li kev nyeem ntawv torque wrench -tightening torques ntawm tib batch ntawm clips yuav tsum ua raws li qhov tsis muaj qhov hloov pauv loj. Mottled nto, hmoov poob, lossis qhov sib txawv torque tseem ceeb qhia tias tsis tsim nyog phosphating, uas yog txwv tsis pub siv.
