Maitiro Ekumisa Yakatenderedzwa PTFE Tepi Kubva Kuzvinamatira Payo Panguva Yekureba Kwenguva Kuchengeta

Unovhura mupumburu we PTFE high-temperature tepi iyo yakagara mukuchengetedza kwemwedzi. Paunenge uchiedza kuisunungura, mitsara inonamatira pamwe chete. Kuzvibvisa zvakasara kunosiya zvakasara zvekunamatira pamusana usina tsvimbo - tepi inoparara.

Dambudziko iri rinonzi interlayer adhesion kana blocking . Zvinoitika nekuda kwezvinhu zviviri: chimiro chePTFE uye silicone adhesive, pamwe nemamiriro ekuchengetedza asina kunaka. Nhau dzakanaka ndeyokuti inogona kudziviswa - zvose nenzira iyo tepi inogadzirwa uye kuti inochengetwa sei.

Aokai PTFE yakagadzirisa nyaya iyi kuburikidza nekuchenjerera maitiro ekutonga. Gwaro iri rinotsanangura kuti sei kuvhara kuchiitika uye zvaungaita kuti uzvidzivirire.

Sei PTFE Tepi Inovhara? Zvikonzero Zviviri

Kuti udzivise kuvharira, unofanirwa kunzwisisa nzira mbiri dzinokonzera.

1. Material properties - PTFE ndangariro uye adhesive zvinokambaira

• Elastic ndangariro yePTFE firimu: Panguva yekugadzira, PTFE mamorekuru maketani anotambanudzwa. Apo tepi yakakuvadzwa zvakasimba uye yakachengetwa pasi pekumanikidzwa kwemwedzi, kushushikana kwemukati zvishoma nezvishoma kunobudisa. Iyo firimu inoedza kudzoreredza kumashure, zvichiita kuti tepi iwedzere kana kuti inonamira kuti ibvise.

• Silicone PSA creep: Silicone pressure-sensitive adhesive haina kusimba - isemi-fluid viscoelastic material. Pasi pekudzvinyirirwa uye kupisa, inoyerera (inokambaira) microscopically, ichipinda mumapores kana kuumbwa kweiyo isiri-tsvimbo kumashure. Kana izvozvo zvangoitika, zvidimbu zvinosungirirana zvachose.

2. Mamiriro ekunze ekuchengetedza - kupisa, hunyoro, uye kudzvinyirira

• Tembiricha iri pamusoro pe40°C: Kupisa kunosimudzira zvinonamira zvinokambaira. PSA viscosity inodonha, uye kuyerera kunowedzera.

• Kunyorova kwepamusoro (> 70% RH): Hunyoro hunogona kukonzera hydrolysis yeadhesive, ichiita kuti pamusoro petacky uye kukurudzira kunamatira.

• Mechanical pressure kubva pakuturikidzana: Mipumburu inorema yakaturikidzana pamusoro peimwe inosvina chinonamira chikatarisana nechekuseri kwechikamu chinotevera, chichimanikidza kubatana kwemuviri.

Iyo Manufacturing Solution - Gradient Winding Tension

Chinhu chimwe chete chinonyanya kukosha mukudzivirira kudzivirira ndechekuti tepi inokuvadzwa sei panguva yekugadzirwa.

1. Nheyo - yakasimba kunze, yakasununguka mukati

Kana mupumburu uchinge wakuvadzwa nekumanikidzana kwakakwira mukati, iwo mukati (padhuze nepakati) ari pasi pekumanikidza kwakasimba. Mushure memwedzi yekuchengetedza, kushushikana ikoko kunosundira kunamira kumashure.

Ne gradient winding tension :

• Outer layers: ronda rakasimba (kuchengeta roll compact)

• Inner layers: ronda zvishoma nezvishoma rakasununguka (kuderedza kusarira kudzvanywa pamusimboti)

Mhedzisiro: iyo musimboti inoitika inenge isina kudzvinyirirwa, saka inonamira inokambaira inenge yabviswa.

2. Zvinoitwa sei - yakavharwa-loop tension control

Aokai PTFE inoshandisa yakavharwa-loop tension control system:

• Sensors inotarisisa iyo chaiyo-nguva roll dhayamita

• Controller inoverengera tension inodiwa ichishandisa proprietary formulas

• Actuators (variable-frequency kana torque motors) zvine simba gadzirisa kushushikana sezvo roll inovaka.

Kupokana kwemhepo kunoderera zvishoma nezvishoma kubva mumhete yemukati kuenda kune yekunze. Izvi zvinodzivirirawo ma-tight-set rolls (apo iwo maturusi emukati anomanikidzwa zvekuti anonetsa kusunungura).

Mamwe Matanho Ekugadzira - Beyond Winding

Gradient tension ndiyo musimboti, asi mamwe matanho ekugadzira anobatsirawo.

1. Sarudza zvinhu zvakakodzera

• High-cohesion silicone PSA: Zvishoma kutsika pasi pekumanikidzwa uye kupisa.

• Yakawedzera PTFE firimu: Iine yakaderera molecular orientation kushushikana pane skived firimu, inoderedza elastic memory mhedzisiro.

2. Isa chivharo chekusunungurwa kumucheto kumashure

Bata iyo isinganamire divi re substrate ne fluorosilicone yekuburitsa coating kana primer. Izvi zvinoderedza simba repamusoro rerutivi rwekumashure, zvichiita kuti zvive zvakaoma zvikuru kuti chisungo chibatanidze kwachiri.

3. Wedzera kuzviparadzanisa nevamwe kune makobvu ekunamira mamakisi

Kune matepi ane akakora kwazvo anonamira akaturikidzana (> 0.05mm), anopindirana kuburitsa bepa kana kuburitsa firimu pakati pemateya. Ichi chiyero chekutadza-chichengetedzeka chekuchengetedza kwenguva refu (kupfuura mwedzi gumi nemaviri).

Yakakodzera Kuchengeta - Basa Rako Mushure meKutenga

Kunyange tepi inogadzirwa zvakanaka inogona kuvhara kana yakachengetwa zvisizvo. Tevedzera mitemo iyi.

1. Kudzora kwezvakatipoteredza - chengetedza kutonhora uye kuoma

2. Kubata uye kurongedza - hapana kudzvinyirira kunorema

• Isa mipumburu yakatwasuka (parutivi rwavo) pamaraki. Usambofa wakaamisa akatwasuka - izvi zvinogona kukonzera kumucheto deformation.

• Shandisa marekeni ekuchengetera pfuma yakawanda. Usaisa mipumburu inodarika 3-4 yakakwira - iyo yepasi mipumburu inosangana yakanyanyisa kudzvanywa.

• Tenderedza mipumburu yekota - shandura nzvimbo inotakura kushushikana nekufambisa pasi rolls kumusoro.

• Chengetedza kurongedzerwa kwepakutanga kwakasimba - kuputira kwepurasitiki kunodzivirira kubva kuguruva uye hunyoro. Kana yakanganiswa, simbisa zvakare nekukurumidza nefirimu repurasitiki.

3. Zvekuita nema rolls aripo angave atova panjodzi

Kana uine rolls dzakachengetwa mumamiriro asina kunaka (kupisa, kunyorova, kurongedzerwa kumusoro), edza sampuli diki usati waisa mukugadzira. Sunungura 1-2 metres uye tarisa kune:

• Kuramba kusingajairike pakusunungura

• Adhesive residu padivi rekuseri

• Inooneka deformation ye roll core

Kana ukaona chimwe cheizvi, dziya mupumburu wacho zvinyoro nyoro (30-40°C kwemaawa mashoma) usati wasunungura - chinonamira chinogona kupfava zvakakwana kuti chibudise zvakachena. Asi kune zvakakosha maapplication, tsiva roll.

Pfupiso - Yakazara Anti-Blocking Cheki

Aokai PTFE inogadzira PTFE yakakwirira-tembiricha tepi ine gradient inomonereka tension seyakajairwa. Nekuchengetedza kwenguva refu (kupfuura mwedzi mitanhatu), tinokurudzira kuwedzera kuvhara mabhegi mumabhegi efoil-barriers uye kuchengetedza mumamiriro ekunze anodzorwa. Bata isu kune tsika yekurongedza sarudzo.

Zviri pamusoro apa zvinopihwa ne Jiangsu Aokai New Materials Technology Co., Ltd.

Kana iwe uchida rumwe ruzivo pamusoro pezvakatemerwa, mamiriro ekushandisa uye zvigadziriso zvakagadziridzwa zvemutsara wezvigadzirwa zvedu, zvinosanganisira PTFE yakakwirira-tembiricha machira, PTFE high-temperature matepi, PTFE mesh mabhandi, seamless bonding mabhandi emuchina, single-sided PTFE jira, yakakwirira-tembiricha inodzivirira inotakura mabhandi, inodzivirira bhandi regirazi, ndapota taura nesu.
