Ntawm cov kab ntim ceev ceev, lub tshuab cua sov sealer yog lub raj mis. Txhua lub sij hawm molten yas sticks rau lub sealing riam, txoj kab nres rau scraping - tua productivity. Txhua lub foob tsis zoo xa cov hnab rov qab rau kev ua haujlwm. Txhua qhov hnav sealing tuag raug nqi ntau txhiab los hloov.
Txoj kev daws teeb meem yog kev dag ntxias yooj yim: thov PTFE high-temperature daim kab xev rau lub sealing nto. Qhov no nyias txheej ntawm PTFE-coated fiberglass, nrog high-temperature silicone nplaum, transforms lub tshav kub sealing txheej txheem.
Aokai PTFE tau muab PTFE daim kab xev rau cov khoom ntim khoom lag luam thiab cov neeg siv kawg rau xyoo. Tsab ntawv xov xwm no suav nrog plaub qhov tseem ceeb ntawm daim ntawv thov - kev tso tawm los tiv thaiv, cov khoom siv tiv thaiv, kev sib khi zoo, thiab kev sib txhuam qis - ntxiv rau cov txheej txheem xaiv tseem ceeb (substrate, kub, nplaum, cov khoom siv kho tshuab) los pab koj xaiv cov kab xev zoo rau koj txoj kab sealing.
Plaub Daim Ntawv Thov Qhov Tseem Ceeb ntawm PTFE Daim Kab Xev nyob rau hauv Kub Sealing
1. Tshem tawm cov nplaum nplaum nplaum - Kev tsim khoom ua haujlwm tsis tu ncua
Qhov no yog PTFE daim kab xev feem ntau ncaj qha kom zoo dua. Ntim cov yeeb yaj kiab suav nrog PE, PP, PET, thiab txhuas cov yeeb yaj kiab sib xyaw yuav ua rau mos thiab lo rau cov hlau tsis muaj qhov sib khi hauv qab cua sov, ua rau lub hnab tawg, zaj duab xis tearing, thiab tsis tshua muaj sijhawm rau kev tu.
PTFE pab: Ultra-low nto zog (18-20 dynes / cm) repels molten plastics thiab kub yaj nplaum. Zaj duab xis tso tawm kom huv si txhua lub voj voog.
Qhov tshwm sim: Tsis lees txais tus nqi poob; Lub tshuab nres lub sijhawm rau kev ntxuav yog txo los ntawm 80-90%.
2. Tiv thaiv cov khoom siv hluav taws xob kub-txheej txheem - Txhim kho cov cuab yeej siv lub neej
Cov riam sib khi los yog cua sov bar yog cov khoom siv hlau precision. Nyob rau tib lub sijhawm, kev sib txhuam los ntawm cov yeeb yaj kiab thiab cov hniav txiav ua rau nws poob, thiab oxidation / corrosion pits saum npoo.
PTFE raws li cov khoom siv tiv thaiv txheej: Cov ntaub nplaum ua raws li tus nqi qis, hloov pauv tau hnav. Hloov daim kab xev yuav siv sij hawm feeb thiab cov nqi pennies piv rau kev kho lossis hloov lub sealing tuag ($500-$5,000+).
Cov txiaj ntsig: Cov cuab yeej siv lub neej txuas ntxiv mus; tuag hloov ncua ncua lengthen.
3. Homogenize Thaum tshav kub kub Distribution - Txhim kho lub foob sib xws
Hwm fiberglass-reinforced PTFE daim kab xev muaj nruab nrab cushioning thiab thermal diffusion zog. Nws them nyiaj rau qhov tsis sib xws me me ntawm cov riam sib khi thiab ntim zaj duab xis ntawm qib micro.
Nws ua haujlwm li cas: Daim kab xev faib ob qho tib si cua sov thiab siab sib npaug ntawm qhov chaw sib khi.
Qhov tshwm sim: Cov ntsaws ruaj ruaj zoo sib xws nrog lub zog tsis sib xws - tsis muaj cov ntsaws ruaj ruaj tsis tiav (xws li) lossis kub kub (pinholes).
4. Kev sib txhuam coefficient qis - Smooth Film Conveying
PTFE's ultra-low kinetic kev sib txhuam coefficient (μ≈0.05-0.10) yog qhov tseem ceeb tshaj qhov kev sib khi. Nws yog dav siv nyob rau hauv kev tsim dab tshos thiab lub tes tsho tub raj ntawm ntsug daim ntawv sau foob (VFFS) tshuab.
Cov txiaj ntsig: Txo kev khiav hauj lwm ntawm ntim zaj duab xis; tiv thaiv zaj duab xis stretching deformation; minimizes static buildup (thaum siv qib anti-static).
Qhov tshwm sim: ruaj khov zaj duab xis noj, tsawg jams.
Aokai PTFE muaj fiberglass-rov qab PTFE daim kab xev tshwj xeeb rau kev siv cua sov sealing. Peb cov silicone PSA yog crosslinked rau 260 ° C tas mus li kev pab cuam, validated los ntawm 1,000-teev kev ntsuam xyuas thaum tshav kub kub laus uas tsis muaj nplaum ooze. Dub anti-static qib (nto kuj 10⁶-10⁹ Ω) yog muaj rau high-ceev zaj duab xis kab.
Thaum tshav kub kub-sealing tej yam kev mob sib txawv heev nyob rau hauv ua hauj lwm kub, compression quab yuam, thiab khiav ceev. Cov kev qhia hauv qab no yuav tsum tau txheeb xyuas thaum xaiv.

Nyob rau hauv cov ntsiab lus , PTFE high-temperature daim kab xev siv rau tshav kub-sealing riam thiab sealing strips muab plaub lub ntsiab tseem ceeb: anti-stick tso tawm (tiv thaiv downtime), kev tiv thaiv cov cuab yeej (txuag nqi tuag hloov), optimized foob zoo (homogenized tshav kub / siab), thiab tsis tshua muaj kev sib txhuam (smooth zaj duab xis pub).
Rau cov txheej txheem ntim cua sov sealing, fiberglass-backed PTFE daim kab xev nrog silicone nplaum nyob rau hauv 0.13 hli los yog 0.18 hli thickness yog cov pov thawj workhorse. Rau cov kab uas nquag txiav los yog siab zoo li qub, hloov mus rau 0.25 hli los yog qib dub anti-static. Nco ntsoov xyuas cov nplaum qhov ntsuas kub tsis tu ncua - silicone PSA, tsis yog acrylic.
