Qhov Tsis Paub Txog Qhov Tsis Txaus Siab Luam Ntawv Phaj Durability

Raws li paub zoo, cov yam tseem ceeb uas cuam tshuam rau cov ntawv luam ntawv lub durability muaj xws li kev siab dhau ntawm cov chais chais rau ntawm lub phaj, cov cushioning ntau dhau ntawm daim pam, cov dej ntws ntau dhau, hnav thiab ua si hauv lub tshuab lub tog raj kheej bearings, tsis sib xws photosensitive txheej ntawm lub phaj, thiab ntau dhau ntawm daim ntawv plua plav ntawm daim pam. Qhov xwm txheej peb ntsib lub sijhawm no yog qhov tshwj xeeb, thiab cov xwm txheej tshwj xeeb yog raws li hauv qab no.

Thaum lub Kaum Ob Hlis Ntuj xyoo tas los, thaum lub caij nyoog siab tshaj plaws ntawm phau ntawv thiab cov khoom lag luam ib ntus, peb lub tuam txhab ob 4787 yim -xim web offset presses tau khiav tsis tu ncua hnub thiab hmo ntuj. Txawm li cas los xij, cov neeg ua haujlwm xovxwm feem ntau tau tshaj tawm tias daim ntawv zoo tsis zoo heev, thiab muaj cov hmoov av ntau ntawm daim pam. Thaum kov los ntawm txhais tes, nws zoo li ib txheej ntawm cov xuab zeb (uas yog cov coarser pulp fibers), ua rau hnyav hnyav ntawm daim hlau thiab cov ntawv luam tawm tsis tshua muaj zog. Feem ntau, tom qab kwv yees li 40,000 txog 50,000 luam tawm, yuav tsum tau nruab ib lub phaj tshiab, tshwj xeeb tshaj yog rau cov pab pawg qis, uas yuav tsum tau hloov phaj ntau zaus. Yog li ntawd, txhua hnub tshuab tso zis tsis tuaj yeem nce, cuam tshuam rau lub sijhawm ntau lawm. Txij li thaum daim ntawv hloov pauv kuj xav tau qee lub sijhawm, txhua tus yuav tsum tau txhuam lawv cov hniav thiab txuas ntxiv siv cov ntawv no mus txog thaum nws tiav lawm.

Tsib hnub tom qab, peb tau hloov mus rau qib siab -cov ntawv zoo hauv tsev, tab sis qhov xwm txheej tseem tsis tau txhim kho loj. Coj txawv txawv? Cov ntawv tam sim no zoo kiag li zoo, yog li vim li cas thiaj li tsis tuaj yeem ua kom cov ntawv luam tawm ntev? Nws puas tuaj yeem muaj teeb meem nrog cov neeg ua haujlwm xovxwm ua haujlwm?

Nrog rau cov kev xav tsis thoob hauv siab, peb tau tshawb xyuas qhov sib piv ntawm tus ciav dej, qhov siab ntawm cov chais rau ntawm lub phaj, daim pam cushioning, thiab lwm yam, thiab pom tsis muaj teeb meem. Cov neeg ua haujlwm kuj tau lees paub peb tias tag nrho cov ntaub ntawv hloov kho tau zoo ib yam li lub quarter dhau los thiab tsis tuaj yeem hloov pauv raws li qhov xav tau. Tom qab kev txiav txim siab ntau, peb muab cov ntawv qub los ntawm cov khoom qub dhau los nrog cov ntawv qub tam sim no thiab pom tias qhov hnav zoo ib yam, nrog rau qhov qis ntsug. Obviously, lub phaj hnav tseem muaj. Tom qab txiav txim tawm yam xws li daim ntawv thiab lub tshuab hloov kho, tsuas yog cov khoom sib txuas nrog lub phaj yog cov phaj yob. Peb pib xaus lus tias cov coarse fibers los ntawm cov ntaub ntawv dhau los tau txuas ntxiv mus rau daim hlau thiab cov roj hmab chais los ntawm daim pam. Tom qab tsheej lab ntawm kev sib hloov thiab compressions, cov fibers no tau ua ruaj khov rau hauv qhov chaw ntawm cov roj hmab rollers, raws li pom hauv daim duab 1.

Daim duab 1 Rubber roller nto nias nrog ntxhib fiber ntau xuab zeb hais Txij li lub sijhawm txwv, peb tau ua qhov kev sim ua ntej ntawm cov txheej txheem qis ntawm thawj pab pawg xim, hloov ob lub nraub qaum thiab so lwm cov roj hmab chais ntxuav ib qho los ntawm ib qho, thiab tom qab ntawd pib luam ntawv. Tom qab ib nrab hnub ntawm kev sim, daim ntawv luam ntawv lub durability rov qab mus rau qhov qub. Tom qab ntawd, cov txheej txheem rov qab ntawm cov khoom seem tau hloov pauv ib los ntawm ib qho. Nyob rau lub sijhawm no, qhov teeb meem ntawm kev luam ntawv phaj coj los ntawm coarse fibers hauv daim ntawv yog thaum kawg daws.
