Yuav Ua Li Cas Tiv Thaiv Wrinkles ntawm PTFE High-Temperature Cloth Thaum Sintering

Jiangsu Aokai Cov Khoom Tshiab, cov chaw tsim khoom ntawm PTFE cov ntaub ntawv kub kub, qhia cov txheej txheem kev cob qhia. Wrinkles generated ntawm PTFE high-temperature ntaub (fiberglass ntaub coated nrog PTFE) thaum lub sij hawm sintering yog tsim los ntawm uneven thermal shrinkage thiab inconsistent kev nyuaj siab ntawm lub substrate, txheej thiab khoom nyob rau hauv high kub. Wrinkle tiv thaiv tsis tuaj yeem tsuas yog tsom rau ntawm qhov cub sintering nkaus xwb; systematic tswj npog tag nrho cov workflow ntawm raw khoom npaj, impregnation, ziab, sintering thiab txias yuav tsum tau.

Cov kev sib txuas tswj tseem ceeb thiab cov kev daws teeb meem tau teev tseg raws li hauv qab no:

I. Raw Material Substrate Control: Tshem Tawm Kev Nyuaj Siab Sab Hauv Ntawm Qhov Chaw

Qhov zoo ntawm fiberglass substrate txiav txim siab qhov nyuaj ntawm kev ua haujlwm tom ntej. Xaiv cov ntaub fiberglass nrog qis twist thiab ruaj khov qauv, featuring tsawg skew thiab uniform ntug nruj, uas muab ib tug zoo thermal shrinkage thaum rhuab.

1. Ua kom tiav pre-dewaxing thiab tshav kub qhov chaw: Lub substrate yuav tsum tau mus rau high-temperature dewaxing thiab thermal chaw kom tshem tawm tag nrho cov weaving nyob rau hauv kev nyuaj siab thiab stabilize nws thermal shrinkage tus nqi. Kev kho mob tsis txaus nyob rau theem no yuav ua rau muaj kev cuam tshuam loj heev uas tsis tuaj yeem cuam tshuam thiab wrinkles thaum cov ntaub nkag mus rau hauv qhov cub sintering.

2. Kev tshuaj xyuas tuaj: Tshawb xyuas cov ntaub tiaj tus nrog cov ncaj los yog cov ntaub ntawv soj ntsuam. Txiav tawm los yog rov qab batch nrog xoob npoo, nruj npoo thiab bulges.

II. Impregnation & Drying Stage: Ua tiav nyias & Uniform txheej

Tsis sib xws txheej thickness ua rau inconsistent shrinkage ntawm molten PTFE thaum sintering, inevitably tsim wrinkles.

1. Ntau txheej txheej dhau los tsis yog txheej hnyav ib zaug: Txais cov txheej txheem rov ua dua thiab ziab nrog cov txheej txheem me me, txawm tias txheej hnyav ib dhau los txhawm rau txhawm rau PTFE resin maj mam. Tsis txhob tuab ib txheej txheej uas ua rau tsis sib haum xeeb hauv thiab sab nraud kom qhuav nrawm.

2. Maj mam kub gradient nyob rau hauv lub qhov cub kom qhuav: Pib nrog cov cheeb tsam uas tsis tshua muaj kub kom volatilize dej thiab auxiliaries maj mam, tiv thaiv sai sai nto ntawm daim tawv nqaij tsim uas ntxiab nrog kev nyuaj siab los ntawm undried puab txheej.

3. Synchronous active tsav rollers nyob rau hauv qhuav seem: Tag nrho cov phau ntawv qhia chais yog lub cev muaj zog-tsav thiab synchronized nrog ntaub kab ceev kom tsis txhob longitudinal stretching ntawm passive dragging.

4. Direct inline hloov mus rau sintering rauv tom qab ziab kom tshem tawm winding indentations. Yog tias qhov nruab nrab winding yuav tsum tau ua, ua kom txias tag nrho cov ntaub ua ntej thiab cua nrog qis nro thiab loj yob txoj kab uas hla kom tsis txhob muaj creases mus tas li nqa mus rau sintering theem.

III. Sintering rauv: Precise Matching ntawm Kub, Airflow thiab Tension

Qhov no yog lub hauv paus tswj ntu rau wrinkle suppression.

1. Kev Tswj Kev Nyuaj Siab: Khaws qhov chaw txaus rau cov cua sov Shrinkage

Thaum PTFE melts saum nws melting point (~ 327 ° C), ob lub substrate thiab txheej ua thermal shrinkage. Kev nruj nruj quab yuam ncab cov ntaub, xauv ruaj khov deformation wrinkles tom qab txias; tsis txaus nro ua rau sagging thiab xoob wrinkles.

· Nruab overfeed rollers ntawm lub qhov cub inlet: Pub npuag rau hauv lub cub tawg nrog 1% ~ 3% overfeed kom them nyiaj rau thermal shrinkage.

· Kaw-loop micro-tension tswj nyob rau hauv lub cub tawg: Real-time tawm tswv yim los ntawm nro sensors kho lub cev muaj zog ceev ntawm txhua seem, tswj tsuas yog tsawg kawg nkaus nro yuav tsum tau kom cov ntaub tiaj tus nyob rau hauv tag nrho cov kub-kub cheeb tsam, nrog cov ntaub cia slack tsis stacking.

2. Temperature Uniformity: Tshem tawm Transverse Shrinkage Discrepancy

Qhov sib txawv ntawm qhov sib txawv ntawm qhov kub thiab txias hauv qhov cub ua rau qhov tsis sib xws ntawm qhov chaw nruab nrab ntawm cov ntaub thiab cov npoo, qhov tseem ceeb ua rau cov kab ntev ntev ntawm cov npoo thiab cov hauv nruab nrab.

· Txwv tsis pub dhau qhov kub thiab txias nyob rau hauv ± 5 ° C: Txais ntau cheeb tsam ywj siab sab saud / qis qis thiab ua kom huab cua kub los ua ib qho chaw sov.

· Tsim nyog sintering nkhaus: Txais ib tug gradient ntawm preheating → high-temperature sintering → qeeb txias kom gradual melting thiab leveling ntawm PTFE tsis instantaneous thermal shock.

· Ua ntej huab cua-flotation sintering furnaces: Npuag raug tshem tawm thiab xa tawm los ntawm sab saud thiab downward cross-blowing cov cua kub tsis muaj kev sib cuag nrog cov chais, hauv paus tshem tawm wrinkles tshwm sim los ntawm kev sib txhuam thiab adhesion, qhov kev daws teeb meem zoo tshaj plaws rau cov ntaub ntawv kub kub ntau lawm.

3. Airflow Control: Tiv thaiv Fabric Fluctuation & Stabilize Leveling

Kev sib hloov cua ceev yuav tsum tsis txhob ntau dhau, thiab airflow yuav tsum tau kho kom tsis txhob muaj kev nruj ntawm cov ntaub sway los ntawm huab cua ncaj qha. Hloov txheej txheej saum toj thiab qis cua nozzles xa cov huab cua tsis tu ncua kom lav kev sib pauv cua sov yam tsis muaj kev cuam tshuam cov ntaub nto.

4. Anti-Wrinkle Roller Cheebtsam rau lub cev sib kis

Nruab nkhaus txiv tsawb spreader chais los yog yas spreader rollers ntawm cov haujlwm tseem ceeb hauv qhov cub thiab qhov hluav taws xob. Lub camber ntawm nkhaus rollers siv lateral stretching quab yuam los ntawm nruab nrab mus rau cov npoo kom zoo tshem tawm cov nplua longitudinal wrinkles. Tag nrho cov cab kuj yuav tsum tau calibrated rau kab rov tav thiab parallel raug tsis tu ncua nrog kev ua yuam kev tsawg dua 0.1mm / m.

IV. Txias & Teeb Theem: Xauv Lub Plawv Ntog Mus Ib Txhis

Npuag tseem thermoplastic thaum tawm ntawm lub qhov cub sintering; Kev ua kom txias tsis zoo yuav ua rau tag nrho cov kev ua haujlwm ua ntej.

1. Kev ua kom txias qeeb qeeb: Tsis txhob tso cua txias ncaj qha tam sim ntawd tom qab qhov chaw kub kub. Dhau los ntawm ib qho insulated qeeb txias seem kom txo qhov kub ntawm PTFE txheej thiab substrate maj mam hauv qab melting point rau tag nrho cov kev ntxhov siab tso tawm.

2. Khaws kev sib kis thiab pub tshaj thaum lub caij txias: Npuag tseem shrinking thaum txias, yog li me ntsis overfeed thiab spreader rollers tseem yuav tsum tau kom txog thaum cov ntaub kub poob qis dua 100 ° C.

3. Tag nrho txias ua ntej kawg winding: Xyuas kom cov ntaub kub mus txog rau hauv chav tsev kub yam tsis muaj residual tshav kub tsub kom, ces cua nrog zoo ib yam tsis tshua muaj nro rau uniform flat rolls.

V. Kev Saib Xyuas Hauv Online & Kho raws sij hawm

Muab cov neeg ua haujlwm tshwj xeeb los tshuaj xyuas cov ntaub nto nrog lub teeb muaj zog ntawm lub qhov hluav taws xob thiab cov cua txias. Fine-tune nro, kub lossis kab ceev tam sim ntawd thaum kuaj pom micro-wrinkles. Nruab cov tshuab tsis sib cuag infrared los saib xyuas lub sijhawm hloov pauv qhov kub thiab txias nrog lub tswb tsis siv neeg rau cov xwm txheej tsis kam lees. Cov tawv nqaij me ntsis tuaj yeem kho tau hauv online ntawm kub calender rollers, tab sis kev tiv thaiv tseem yog qhov tseem ceeb tshaj plaws.

Cov ntsiab lus tseem ceeb

Tsim nyog ruaj khov substrate cua sov teeb + nyias nyias txheej ntau txheej txheej + txaus overfeed & micro nro thaum sintering + zoo ib yam transverse rauv kub + auxiliary spreader rollers = wrinkle-free sintered PTFE daim ntaub.

Feem ntau wrinkle tsis xws luag tuaj yeem raug tshem tawm los ntawm kev tswj xyuas nruj thiab ntsuas kub sib xws. Txawm tias huab cua-flotation furnaces tuaj yeem tsim wrinkles yog cov txheej txheem tsis sib haum xeeb substrate yam ntxwv, uas ua pov thawj cov txheej txheem tag nrho-txheej txheem kev tswj ntau dua ib qho khoom siv optimization.
