Kev siv tooj liab hauv kev lag luam teeb

Daim ntawv thov ntawmToojhauv Paper Industry
Nyob rau hauv cov ntaub ntawv tam sim no-hloov zej zog, kev siv ntawv yog loj heev.Daim ntawv zoo nkaus li yooj yim rau ntawm qhov chaw, tab sis cov txheej txheem papermaking yog qhov nyuaj heev, yuav tsum muaj ntau cov kauj ruam thiab siv ntau lub tshuab, suav nrog cov tshuab cua txias, evaporators, beaters, paper machines, thiab ntau dua.Ntau yam ntawm cov khoom no, xws li: ntau yam kev sib hloov cua sov, cov menyuam, tshuab tuav, semi-kua twj thiab xaim meshes, feem ntau yog ua los ntawm cov hlau alloys.Piv txwv li, tam sim no siv Foursdrinier xaim ntawv tshuab txau cov ntaub ntawv npaj rau hauv daim ntaub nrawm nrawm nrog cov mesh zoo (40-60 mesh).Lub mesh yog woven los ntawm tooj dag thiab phosphor bronze hlau, thiab nws yog dav heev, feem ntau tshaj 20 ko taw (6 meters), thiab yuav tsum tau ceev kom zoo meej.Lub mesh txav mus los ntawm ib tug me me tooj dag los yog tooj liab rollers, thiab thaum nws hla nrog lub pulp sprayed rau nws, noo noo yog nqus los ntawm hauv qab.Lub mesh vibrates tib lub sij hawm los khi cov me me fibers hauv lub pulp ua ke.Cov tshuab ntawv loj muaj qhov loj mesh, txog 26 feet 8 ntiv tes (8.1 meters) dav thiab 100 feet (3 0.5 meters) ntev.Cov ntaub ntub dej tsis yog tsuas yog muaj dej xwb, tab sis kuj muaj cov tshuaj siv hauv cov txheej txheem papermaking, uas yog corrosive heev.Txhawm rau kom ntseeg tau tias cov ntawv zoo, cov ntaub ntawv mesh yuav tsum nruj heev, tsis yog tsuas yog siab zog thiab elasticity, tab sis kuj tiv thaiv corrosion ntawm pulp, cam khwb cia tooj liab alloy muaj peev xwm.
Kev siv tooj liab hauv kev lag luam luam ntawv
Hauv kev luam ntawv, tooj liab phaj yog siv rau photoengraving.Tom qab lub npoo-polished tooj liab phaj yog sensitized nrog ib tug photosensitive emulsion, ib tug yees duab duab yog tsim nyob rau ntawd.Photosensitive tooj liab phaj yuav tsum tau rhuab kom harden cov kua nplaum.Txhawm rau kom tsis txhob softening los ntawm tshav kub, tooj liab feem ntau muaj ib qho me me ntawm cov nyiaj los yog arsenic los ua kom cov softening kub.Tom qab ntawd, lub phaj yog etched los ua ib qho chaw luam tawm nrog cov qauv ntawm concave thiab convex dots faib.Lwm qhov tseem ceeb ntawm kev siv tooj liab hauv kev luam ntawv yog tsim cov qauv los ntawm kev teeb tsa tooj dag font blocks ntawm cov tshuab ntaus ntawv tsis siv neeg.Hom blocks feem ntau yog tooj dag, qee zaum tooj liab lossis tooj liab.
Kev siv tooj liab hauv kev lag luam saib
Cov moos, lub sijhawm thiab cov khoom siv nrog lub tshuab ua haujlwm yog tam sim no tsim nyob rau hauv uas feem ntau ntawm cov haujlwm ua haujlwm yog ua los ntawm "horological tooj dag".Cov hlau muaj 1.5-2% txhuas, uas muaj cov khoom ua haujlwm zoo thiab tsim nyog rau ntau lawm.Piv txwv li, cov iav raug txiav los ntawm cov hlau ntev extruded tooj dag, lub log tiaj tus yog xuas nrig los ntawm cov tuab tuab, tooj dag lossis lwm yam tooj liab alloys yog siv los ua engraved moos lub ntsej muag thiab cov ntsia hlau thiab cov pob qij txha, thiab lwm yam. Muaj ntau cov watches pheej yig yog ua los ntawm gunmetal (tin-zinc bronze), los yog plated nrog npib tsib xee nyiaj (dawb tooj liab).Qee lub moos nto moo yog ua los ntawm cov hlau thiab tooj liab alloys.Tus British "Big Ben" siv ib rab phom phom rau tes tes thiab 14-foot-ntev tooj liab raj rau feeb tes.Lub Hoobkas saib niaj hnub, nrog tooj liab alloy ua cov khoom tseem ceeb, ua tiav nrog cov xovxwm thiab cov pwm meej, tuaj yeem tsim 10,000 txog 30,000 watches ib hnub twg ntawm tus nqi qis heev.
Kev siv tooj liab hauv Kev Lag Luam Pharmaceutical
Hauv kev lag luam kws tshuaj, txhua yam ntawm steaming, boiling thiab nqus cov khoom siv yog ua los ntawm cov tooj liab ntshiab.Hauv cov khoom siv kho mob, zinc cupronickel tau siv dav.Copper alloy kuj yog ib qho khoom siv rau spectacle thav duab thiab lwm yam.
