Fasteners yog cov khoom siv los txuas thiab fasten qhov chaw, thiab yog cov khoom siv ntau heev uas siv rau fastening thiab daim ntawv thov.Nws cov duab ntxoov ntxoo tuaj yeem pom ntawm txhua yam ntawm cov tshuab, khoom siv, tsheb, nkoj, kev tsheb ciav hlau, txuas hniav, cov tsev, cov qauv, cov cuab yeej, cov cuab yeej, cov cuab yeej thiab cov khoom siv hluav taws xob.Nws muaj ntau yam kev qhia tshwj xeeb, cov yam ntxwv sib txawv thiab kev siv, thiab qib siab ntawm standardization, serialization, thiab generalization.Muaj ntau ntau hom fasteners, uas feem ntau yog muab faib ua kaum ob pawg, txhua yam yog: bolts, studs, screws, ceev, self-tapping screws, ntoo screws, washers, pins, assemblies thiab txuas sub-assemblies, rivets, vuam. rau tes, Hlau threaded tes tsho.Txhua pawg muaj nws tus kheej ua haujlwm hauv txhua qhov chaw.Raws li ib qho ntawm cov khoom lag luam nrog qhov loj tshaj plaws ntshuam thiab xa tawm ntim nyob rau hauv Suav teb, fasteners ua raws li thoob ntiaj teb cov qauv, uas txhawb Suav fastener tuam txhab uas muag mus fim lub ntiaj teb no thiab txhawb fastener tuam txhab uas muag kom muaj kev koom tes nyob rau hauv thoob ntiaj teb kev koom tes thiab kev sib tw.Yuav kom siv cov fasteners zoo dua, peb yuav tsum tuav cov fasteners hauv lub sijhawm.Yog li thaum peb ntxuav cov fasteners peb feem ntau pom muaj rau qhov teeb meem nrog qee qhov teeb meem tseem ceeb.
1. Kev kis kab mob thaum lub sijhawm.Tom qab cov fasteners yog quenched, lawv raug ntxuav nrog ib tug silicate ntxuav thiab ces yaug.Cov teeb meem ntawm qhov chaw tshwm sim los ntawm silicate residue ntawm lub fastener nto vim yog dej ntws tsis tiav.2. Lub stacking ntawm fasteners yog unscientific.Cov fasteners qhia pom cov tsos mob ntawm cov xim tom qab tempering, qhia tias cov fasteners tau kis kab mob nrog cov tshuaj ntxuav thiab quenching roj thaum lub sij hawm ntxuav.Cov txiaj ntsig kev soj ntsuam ntawm cov roj quenching tau lees paub tias vim yog qhov tsis muaj kev tshawb fawb ntawm cov fasteners thaum lub sij hawm cua sov, cov fasteners muaj me ntsis oxidation nyob rau hauv cov roj quenching, uas yog yuav luag negligible.Qhov xwm txheej no muaj feem cuam tshuam rau kev ntxuav, tsis yog cov roj quench.
3. Cov kua tank yuav tsum tau nchuav tsis tu ncua, thiab cov qib concentration ntawm cov lye nyob rau hauv lub tank yaug yuav tsum tau xyuas ntau zaus.
4, caustic soda raug mob.Cov tshuaj ntxuav alkaline muaj cov tshuaj fluoride thiab calcium uas tuaj yeem hlawv los ntawm cov hlau fasteners thaum kho cua sov thiab tawm ntawm qhov chaw ntawm lub fastener.Kev tu kom huv si thiab yaug cov fasteners ua ntej kev kho cua sov yog pom zoo kom tshem tawm tag nrho cov alkaline residues uas ua rau fastener burns.
5. Kev tso dej tsis zoo tuaj yeem txhawb kev txhim kho corrosion.Nws raug nquahu kom hloov cov dej yaug dej tsis tu ncua.Tsis tas li ntawd, ntxiv cov tshuaj tiv thaiv xeb rau cov dej kuj yog ib txoj hauv kev zoo.
6. xeb ntau dhau.Yog tias cov roj quench yog dhau lawm, nws raug nquahu kom ntws cov roj qub thiab ntxiv cov roj tshiab rau kev saib xyuas cov txheej txheem thiab tua cov roj tu thoob plaws hauv lub voj voog.
