Qhov ceev ntawm daim ntawv-raws li substrate nyob rau hauv ntub kev sib txhuam discs feem ntau yog li ntawm 0.9 mus rau 1.4 g / cm³. Txawm hais tias qhov ntau yam no yuav txawv nyob ntawm cov txheej txheem tsim khoom tshwj xeeb thiab cov qauv siv los ntawm cov tuam txhab sib txawv, nws feem ntau poob rau hauv cov kev txwv no. Rau cov duab meej, thov sab laj nrog cov khoom lag luam tshwj xeeb lossis hu rau cov chaw tsim khoom.
Kev sib txhuam ntub dej yog cov ntaub ntawv sib txhuam uas siv dav hauv cov haujlwm xws li kev tsim kho tsheb thiab kev tsim kho tshuab; lawv feem ntau yog tsim los ntawm daim ntawv-raws li substrate, txheej nplaum, thiab txheej txheej khoom sib txhuam. Daim ntawv -raws li substrate ua lub hauv paus ntawm lub disc, muab kev txhawb nqa thiab ua raws li cov khoom sib txuas. Yog li, dab tsi yog qhov ceev ntawm daim ntawv no -raws li substrate?
Qhov ntom ntom ntawm daim ntawv -Raws li substrate
Qhov ceev ntawm daim ntawv-raws li substrate nyob rau hauv ntub txhuam discs feem ntau poob ntawm 0.9 thiab 1.4 g / cm³. Qhov no sib txawv raws li cov txheej txheem ntau lawm thiab cov ntaub ntawv formulations ntawm txawv manufacturers. Qhov ceev yog txhais raws li qhov loj ntawm ib chav tsev ntim; rau daim ntawv -raws li substrate ntawm ntub kev sib txhuam discs, qhov ceev yog feem ntau cuam tshuam los ntawm tej yam xws li hom pulp, noo noo cov ntsiab lus, thiab hom thiab ntau npaum li cas ntawm additives siv.
Cov yam ntxwv cuam tshuam qhov ntom ntawm daim ntawv -Raws li substrate
Pulp Hom:Ntau hom pulp muaj cov khoom sib txawv ntawm fiber ntau-xws li qhov ntev, tuab, thiab lub zog- uas cuam tshuam rau qhov ntom ntawm cov substrate.
Cov dej noo:Cov ntsiab lus noo noo nyob rau hauv lub pulp yuav tsum nruj me ntsis tswj thaum lub sij hawm tsim khoom. Ntau dhau los yog tsis txaus noo noo tuaj yeem cuam tshuam rau qhov ntom ntom thiab kev ua haujlwm ntawm lub substrate.
Hom thiab ntau npaum ntawm Additives:Txhawm rau txhim kho kev ua haujlwm ntawm cov ntaub ntub dej sib txhuam, cov chaw tsim khoom feem ntau muab cov khoom siv xws li cov resins thiab cov hmoov ntxhia rau hauv daim ntawv -raws li substrate. Cov hom tshwj xeeb thiab qhov ntau ntawm cov additives no kuj cuam tshuam rau lub substrate qhov ntom.
Daim ntawv thov thiab kev ua haujlwm yuav tsum tau ua ntawm ntub txhuam discs
Cov kev sib txhuam ntub dej yog siv dav hauv kev siv tsheb thiab kev tsim kho tshuab, feem ntau rau kev sib kis ntawm lub zog thiab nres. Txhawm rau kom muaj kev ruaj ntseg thiab txhim khu kev qha, cov qauv hauv teb chaws yuav tsum nruj me ntsis txog cov kev ntsuas xws li kev sib txhuam cov yam ntxwv thiab tus nqi hnav. Piv txwv li, GB/T 21955-2008, *Technical specifications for paper-based friction discs for agricultural and forestry tractors and machinery*, yuav tsum muaj kev sib txhuam coefficient ntawm 0.11–0.14, kev sib txhuam zoo li qub ntawm 0.12–0.17 ⁻ ntawm tus nqi tsawg dua 5 ⁻ cm³/J.

Hauv cov ntsiab lus, qhov ceev ntawm daim ntawv -raws li ntub kev sib txhuam discs feem ntau yog li ntawm 0.9 txog 1.4 g / cm³, nrog rau cov nqi tshwj xeeb cuam tshuam los ntawm ntau yam. Txhawm rau kom ruaj khov thiab txhim khu kev qha, cov tuam txhab tsim khoom yuav tsum nruj me ntsis tswj cov txheej txheem tsim khoom thiab cov khoom tsim kom tau raws li lub teb chaws cov qauv thiab cov neeg siv khoom.
