Fiberglass npuag thermal shrinkage yog thawj qhov ua rau PTFE daim kab xev seem tsis ruaj khov. Ntawm PTFE sintering kub (360-400 ° C), residual weaving stress yog tso tawm. Yog tias tsis muaj kev txwv, cov ntaub shrinks; Yog tias txwv tsis pub, kev ntxhov siab latent raug kaw, ua rau tom qab shrinkage thaum lub sij hawm kho (150-200 ° C) thiab siv cua sov kawg. Kev daws: siv pre-heat-set fiberglass nrog <0.5% shrinkage ntawm 400 ° C, tshem tawm cov residual kev nyuaj siab ua ntej txheej.

Thickeners nyob rau hauv PTFE emulsion pab plaub lub luag haujlwm tseem ceeb: tshem tawm stabilization (tiv thaiv kev teeb tsa ntawm cov khoom ntom ntom PTFE), shear-thinning tus cwj pwm (siab viscosity ntawm so, tsis tshua muaj kev ntxhov siab rau txheej yooj yim), kev nkag siab tob ( tswj cov khoom thauj khoom ntawm fiberglass npuag), thiab ua kom cov yeeb yaj kiab sib xyaw ua ke (previousness). Qhov tseem ceeb yuav tsum tau: thickeners yuav tsum decompose kiag li ntawm ~ 380 ° C sintering kub, tawm xoom tshauv residue los tswj txheej purity thiab hluav taws xob rwb thaiv tsev.

Aokai PTFE tau nthuav tawm nws cov khoom lag luam tag nrho ntawm APFE Shanghai 2026 (Lub Rooj Muag Khoom 6T602, Hall 6). Cov khoom tshwj xeeb muaj xws li fiberglass-reinforced PTFE tapes, ntshiab PTFE films, anti-static qib, thiab high-temperature conveyor siv - npog cov zaub mov, PV lamination, lithium roj teeb, electronics, thiab ntim. Lub exhibition pib mus txog rau lub rau hli ntuj 26. Tag nrho cov khoom txhawb kev cai specifications.

PTFE nto kev kho mob rau kev sib khi adhesion siv ob txoj hauv kev: kub-kub melting (zoo tshaj huab cua tsis kam, 9.5 MPa lub zog nrog coupling tus neeg sawv cev, tab sis tso tawm cov pa roj carbon monoxide) thiab sodium-naphthalene etching (5 MPa tam sim adhesion, nqaim 24-48 teev lub qhov rais, pov tseg txaus ntshai). Xaiv raws li kev tswj hwm ib puag ncig thiab lub sijhawm ntev vs.

Kev ntsuas PTFE emulsion zoo suav nrog rau qhov ntsuas tseem ceeb: cov ntsiab lus khoom (60 ± 2% ib T / FSI 067-2021), pH (9.0-11.0), particle loj tis (laser diffraction / DLS), viscosity (12-30 mPa·s ntawm 25 ° C), thermal stability (freezet-zoo li, centrifugal). Phau ntawv qhia no suav nrog cov qauv kev sim rau txhua qhov ntsuas.

Txhawm rau thov PTFE daim kab xev kub kub ruaj khov rau ntawm qhov nkhaus thiab qhov tsis sib xws yam tsis muaj npuas thiab ntug warping, txheej txheem kev ua haujlwm yog qhov tseem ceeb, suav nrog kev ua kom zoo hauv substrate pretreatment, kev tshaj lij daim ntawv thov thiab kev ntsuas kom raug. Ntawm lawv, substrate pretreatment yog cov kauj ruam tseem ceeb tshaj plaws, uas txiav txim siab txog 70% ntawm qhov kawg ntawm cov nyhuv.

Tawm tsam cov keeb kwm yav dhau los ntawm cov kev cai ib puag ncig nruj zuj zus, PFOS / PFOA-dawb PTFE emulsion yog cov khoom tsim kho tshiab tsim los hloov cov txheej txheem PFOA-muaj cov txheej txheem polymerization. Nws tuav cov khoom tseem ceeb ntawm PTFE thaum txhim kho ib puag ncig tus phooj ywg thiab kev nyab xeeb kev noj qab haus huv.

Lub thermal expansion coefficient ntawm PTFE siab kub ntaub tsis yog tus nqi ruaj. Nws tseem qis qis ntawm chav tsev kub txog 100 ° C (kwv yees li 0.5 × 10⁻⁵ / ° C), tab sis nce siab hauv qhov kub thiab txias.

Raws li cov kws tshaj lij kev lag luam ntawm PTFE cov ntaub ntawv kub kub, Jiangsu Aokai Cov Khoom Siv Tshiab tau qhia cov txheej txheem slitting. Txhawm rau kom tsis txhob burrs, delamination thiab qhov sib txawv ntawm qhov sib txawv thaum lub sij hawm slitting, nws yog ib qho tseem ceeb rau kev tswj hwm plaub lub ntsiab lus tseem ceeb: txiav cov cuab yeej, khoom siv, cov khoom siv raw.

Raws li ib tug thawj chaw tsim tshuaj paus ntawm PTFE high-temperature tapes, Jiangsu Aokai Cov ntaub ntawv tshiab no piav qhia txog qhov cuam tshuam ntawm cov txheej txheem cua txias thiab cov cua txias ntawm qhov kev ua tau zoo ntawm PTFE high-temperature tapes.I.
