Yuav Ua Li Cas Tsis Txhob Rolled PTFE Daim Kab Xev Los Ntawm Kev Ua Rau Nws Tus Kheej Thaum Lub Sij Hawm Ntev

Koj qhib ib yob ntawm PTFE high-temperature daim kab xev uas tau zaum hauv cia rau lub hlis. Thaum koj sim unwind nws, cov khaubncaws sab nraud povtseg yog daig ua ke. Peeling lawv sib nrug tawm cov nplaum seem nyob rau sab tsis-stick rov qab - daim kab xev puas lawm.

Qhov teeb meem no yog hu ua interlayer adhesion los yog thaiv . Nws tshwm sim vim yog ob yam: qhov xwm txheej ntawm PTFE thiab silicone nplaum, ntxiv rau cov khoom tsis zoo. Qhov xwm zoo yog tias nws tuaj yeem tiv thaiv tau - ob qho tib si los ntawm kev tsim daim kab xev thiab yuav khaws nws li cas.

Aokai PTFE tau daws qhov teeb meem no los ntawm kev tswj cov txheej txheem ceev. Phau ntawv qhia no piav qhia tias vim li cas kev thaiv kev tshwm sim thiab koj tuaj yeem ua dab tsi kom zam tau.

Vim li cas PTFE Daim Kab Xev Block? Ob lub hauv paus ua rau

Txhawm rau tiv thaiv kev thaiv, koj yuav tsum nkag siab txog ob lub tswv yim uas ua rau nws.

1. Cov khoom siv - PTFE nco thiab nplaum nplaum

• Elastic nco ntawm PTFE zaj duab xis: Thaum lub sij hawm ntau lawm, PTFE molecular chains yog stretched. Thaum daim kab xev raug kaw nruj nreem thiab khaws cia rau hauv siab rau lub hlis, kev ntxhov siab sab hauv maj mam tso tawm. Zaj duab xis sim thim rov qab, ua rau daim kab xev rau warp los yog cov nplaum rau detach.

• Silicone PSA creep: Silicone siab-rhiab nplaum nplaum tsis yog ib qho khoom - nws yog cov khoom siv viscoelastic semi-kua. Nyob rau hauv lub siab thiab kub, nws ntws (creeps) microscopically, nkag mus rau hauv lub pores los yog kev ntxhib los mos ntawm cov tsis-stick rov qab sab. Thaum ua li ntawd, cov khaubncaws sab nraud povtseg mus tas li.

2. Sab nraud cia tej yam kev mob - kub, av noo, thiab siab

• Kub siab tshaj 40 ° C: Kub ua kom nrawm nrawm nrawm nrawm. PSA viscosity poob, thiab ntws nce.

• Cov av noo siab (> 70% RH): Cov dej noo tuaj yeem ua rau hydrolysis ntawm cov nplaum, ua rau saum npoo tacky thiab txhawb nqa adhesion.

• Mechanical siab los ntawm stacking: hnyav rolls stacked nyob rau sab saum toj ntawm txhua lwm yam nyem lub nplaum txheej tiv thaiv sab nraub qaum ntawm txheej tom ntej, yuam lub cev sib txuas.

Txoj Kev Tsim Kho - Gradient Winding Tension

Ib qho tseem ceeb tshaj plaws hauv kev tiv thaiv kev thaiv yog li cas daim kab xev raug mob thaum lub sijhawm tsim khoom.

1. Lub hauv paus ntsiab lus - nruj sab nraud, xoob sab hauv

Yog hais tias ib tug yob yog qhov txhab nrog qhov nro tsis tu ncua thoob plaws, cov txheej sab hauv (ze ntawm lub hauv paus) yog nyob rau hauv cov kev nyuaj siab compressive. Tom qab lub hlis ntawm kev khaws cia, qhov kev ntxhov siab ntawd thawb lub nplaum rau sab nraub qaum.

Nrog gradient winding nro :

• Cov txheej txheej txheej: mob nruj (kom cov yob compact)

• Sab hauv cov khaubncaws sab nraud povtseg: qhov txhab zuj zus looser (kom txo qis residual siab ntawm lub hauv paus)

Qhov tshwm sim: cov kev paub tseem ceeb yuav luag tsis muaj kev txhawb nqa, yog li cov nplaum nplaum yuav raug tshem tawm.

2. Nws ua li cas - kaw-voj nro tswj

Aokai PTFE siv lub kaw-voj nro tswj qhov system:

• Sensors saib xyuas lub sijhawm tiag tiag yob txoj kab uas hla

• Tus maub los suav qhov nro uas yuav tsum tau siv cov qauv tsim

• Actuators (variable-frequency lossis torque motors) dynamically kho qhov nro thaum yob tsim

Lub winding nro txo ​​qis los ntawm lub nplhaib puab mus rau lub nplhaib sab nraud. Qhov no kuj tiv thaiv kom nruj-teeb rolls (qhov twg cov khaubncaws sab nraud povtseg ua kom compressed uas lawv nyuaj rau unwind).

Kev ntsuas ntau lawm - Tshaj dhau Winding

Gradient nro yog qhov tseem ceeb, tab sis lwm cov txheej txheem tsim khoom kuj pab.

1. Xaiv cov khoom tsim nyog

• High-cohesion silicone PSA: Tsis tshua muaj siab nkag hauv siab thiab kub.

• Extruded PTFE zaj duab xis: Muaj qis molecular orientation kev nyuaj siab dua skived zaj duab xis, txo elastic nco los.

2. Siv cov txheej txheem tso tawm rau sab nraub qaum

Kho sab tsis-nplaum ntawm lub substrate nrog fluorosilicone tso txheej los yog primer. Qhov no txo ​​qis lub zog saum npoo ntawm sab nraub qaum, ua rau nws nyuaj rau cov nplaum nplaum rau nws.

3. Ntxiv kev cais lub cev rau cov qib nplaum tuab

Rau cov ntaub nplaum nrog cov nplaum nplaum tuab heev (> 0.05mm), sib cuam tshuam cov ntawv tso tawm lossis tso zaj duab xis ntawm txheej. Qhov no yog ib qho kev ntsuas tsis zoo rau kev khaws cia ntev (ntau tshaj 12 lub hlis).

Kev Cia Khoom Zoo - Koj Lub Luag Haujlwm Tom Qab Kev Muag Khoom

Txawm tias qhov zoo tshaj plaws-tsim daim kab xev tuaj yeem thaiv yog tias khaws cia tsis raug. Ua raws li cov cai no.

1. Kev tswj ib puag ncig - kom nws txias thiab qhuav

2. Kev tuav thiab stacking - tsis muaj qhov hnyav

• Muab cov yob horizontally (ntawm lawv sab) ntawm racks. Tsis txhob sawv ntsug - qhov no tuaj yeem ua rau ntug deformation.

• Siv cov racks cia rau cov khoom loj. Tsis txhob muab cov yob ntau tshaj 3-4 siab - cov yob hauv qab yuav muaj kev kub ntxhov ntau dhau.

• Tig rolls peb lub hlis twg - hloov txoj hauj lwm ntawm kev ntxhov siab los ntawm kev txav hauv qab yob mus rau sab saum toj.

• Khaws cov ntim khoom qub kom zoo - lub hnab yas tiv thaiv plua plav thiab av noo. Yog tias puas lawm, rov kaw tam sim nrog cov yeeb yaj kiab yas.

3. Yuav ua li cas rau cov yob uas twb muaj lawm uas yuav muaj kev pheej hmoo

Yog tias koj muaj cov yob uas tau muab khaws cia rau hauv qhov tsis zoo (kub, av noo, stacked siab), sim ib qho qauv me me ua ntej muab tso rau hauv ntau lawm. Tshem tawm 1-2 meters thiab kos rau:

• Qhov txawv txav tsis zoo thaum unwinding

• Adhesive residue nyob rau sab nraub qaum

• Pom pom deformation ntawm yob core

Yog tias koj pom ib qho ntawm cov no, sov lub yob maj mam (30-40 ° C rau ob peb teev) ua ntej unwinding - cov nplaum yuav soften txaus los tso kom huv si. Tab sis rau cov ntawv thov tseem ceeb, hloov cov yob.
