Maitiro ePTFE Tape Yekucheka Kupera Kwechiso Chimiro Inobata Adhesive Oozing uye Edge Kusimudza

Rini PTFE high-temperature tepi inoshandiswa kune inopisa sealer, mutungamiri roller, kana kusungirirwa kwepamusoro, matambudziko maviri anowanzoonekwa anogona kuoneka pamicheto: adhesive oozing (glue inobuda kubva kumucheto wakachekwa) uye kumucheto kusimudza (tepi yepende inoputika kubva kune substrate).

Izvi zvinokanganisa zvinowanzorongedzerwa kune imwe sosi: kunaka kweiyo slitting (kucheka) maitiro. Chimiro chechiso chekupedzisira chekucheka - chingave chakatsetseka kana chakashata, chakachena kana chakasvibiswa - chinotarisa maitiro ezvokunamatira pamucheto.

Aokai PTFE inodzora slitting mhando kudzivirira nyaya idzi. Gwaro iri rinotsanangura kuti kupera kwechiso morphology kunokonzeresa sei kuyerera uye kusimudza, uye kuti tepi yakatsemurwa mupendero inofanirwa kutaridzika sei.

Chimiro chePTFE Tape Muchinjikwa-Chikamu

Kuti unzwisise kuti iyo yakachekwa yekupedzisira kumeso inokanganisa sei kuita, tanga warangarira chimiro chetepi. PTFE high-temperature tepi inowanzo sanganisira:

• Fiberglass jira substrate (kusimbisa)

• PTFE coating (isina-tsvimbo pamusoro)

• Silicone pressure-sensitive adhesive layer (bonding side)

Slitting zvinoreva kucheka kwenguva yakareba iyi composite yakamanikana kuita mipumburu madiki. Iyo morphology yeakachekwa magumo kumeso - yakatsetseka kana yakakasharara, yakatwasuka kana yakazungunuka - uye dimensional kugara (kufuratira, verticality, kushomeka kwekunamira kana tambo) inokonzeresa zvikanganiso zviviri.

Iyo Yakachekwa Kupera Kwechiso Kunokonzera Kunamatira Oozing

Adhesive oozing zvinoreva kunyura kusingatarisirwe kwekunamira kubva kumucheto wetepi, kusvibisa zvakasungwa workpiece kana tepi reverse side. Chiso chakachekwa chinopa simba rakananga.

1. Kudhonza uye tambo mhedzisiro kubva pakachekwa

Kana iyo slitting blade yakagomara kana kona yekucheka isina kufanira, blade inodhonza uye inotambanudza iyo inochinjika silicone PSA pane kuicheka zvakachena. Izvi zvinokonzera:

• Microscopic glue filaments nemaburrs: Kunama kwakabvaruka kunosiya tambo dzeglue dzemhando yepamusoro kana maflakes akabudikira kubva kumucheto wetepi. Aya 'glue ndebvu' anotamisa nekutyoka zviri nyore panguva yekugadziriswa kana kuchengetedza, zvichigadzira chimiro chekuona chekunamira kuyerera.

• Adhesive migration yakananga kumacheto: Simba rekudhonza panguva yekutsemura rinokweva rinonamira kumagumo kumeso uye kunyangwe chikamu chemuchinjiko che substrate. Kana tepi ichikuvadzwa kuita mupumburu, iyo extruded adhesive inonamatira kune PTFE kumashure kweiyo yakatarisana layer. Pakusunungura, glue yakasara inoonekwa pamipendero - iyo yekare kutadza kutadza.

2. Extrusion mhedzisiro kubva kune isina kuenzana magumo zviso

Zviso zvisina kumira zvakanaka zvinoguma (wavy surfaces, protrusions, inclined planes) zvinotakura abnormal lateral pressure panzvimbo dzakasimudzwa kana tepi yanyatsokuvara kuita rolls. Silicone PSA is viscoelastic - inokambaira pasi pekumanikidzwa kwakasimba, kunyanya panguva yekuchengetera kana kutakura. Iyi dzvinyiriro inotyaira adhesive kuyerera kubva kumusoro-kudzvanywa protrusions kuenda kuzasi-kudzvanywa voids, kusvina kubva kumagumo kumeso.

3. Yakaputsika kumucheto chisimbiso pakati pekunamatira uye substrate

Yakanaka slitting inopa flush muchinjiko-chikamu inobatanidza ese maseru. Kutsemura kwakashata kunogona kukonzera delamination uye kupatsanurwa pakati pekunamira nefiberglass, kana magadziko ari pamuchinjiko-chikamu, kutyora yakavharwa mupendero chimiro. Kana yapiswa, inonamira yakapfava inopinda nekunze kuburikidza neaya madiki-channel. Pakupisa kwepamusoro (semuenzaniso, zvinovhara kupisa zvinodarika 200°C), mvura inonamira inonaya, uye zviso zvakakasharara zvinosimudza njodzi yekubuda mvura.

Iyo Yakachekwa End Iso Inokonzera Edge Kusimudza

Kusimudza kumucheto (Edge lifting) kunoreva kupatsanurwa kwakangoerekana kwaitwa kwematepi echeto kubva panzvimbo dzakasungwa pasi pekunetsekana kana kupisa mushure mekushandisa.

1. Thinned edge adhesive layer - weak bonding zone

Mashizha akagomara kana zvisina kufanira kutsemura maparamita anoburitsa compression-cut effect: blade inosvina zvinhu padivi pane kuichekerera zvakachena. Adhesive inoyerera ichienda nechemberi pasi pekudzvanyirirwa, ichitungamira kune yakaonda zvakanyanya kana kupotsa inonamira pamucheto wekunze. Iyi nzvimbo yekumucheto ine simba rakadzika kwazvo rekubatanidza pane tepi muviri, saka kusimudza mupendero kunotanga pano pasi pekunetseka kudiki kana kushushikana kwekushisa.

2. Substrate burrs uye delamination - wedging effect

PTFE tepi substrate ine girazi fiber. Kutsemura kwakashata kunokwevera kunze fiberglass filaments pane kuacheka zvakachena, achisiya akaomesesa fiberglass burrs kumagumo kumeso. Munguva yekurarisa, aya mabhura akaomarara anosimudzira tepi mupendero, achigadzira madiki madiki pakati peanonamira pamusoro uye workpiece - ichivharira kuzara kwakabatana uye kukonzera kusimudza.

Kana kutsemuka kuchikonzera delamination pakati pePTFE coating uye fiberglass kumicheto, kusapindirana kwemafuta ekuwedzera mazinga anounza kushushikana kwemukati mushure mekupisa, kupepeta micheto kubva kune substrates.

3. Serrated kana notched edges - stress concentration

Inooneka serrations uye notches inoteya mweya uye inodzivirira yakazara pamusoro pekubatana mushure mekubatana. Kunyangwe macroscopically flat edges ane micro-kusaenzana anoona kusaenzana kwekupisa kwekuwedzera kana kuchipisa, kubvarura iyo bonding interface uye kukonzeresa kusimudzwa kwemupendero.

4. Kusvibiswa kubva kune extruded adhesive - yakaderedzwa edge tack

Yakanyanya kunyungudika yakanamatira inogona kunamatira zvakare kune tepi yekupedzisira, ichichinja makemikari emhando yemarginal adhesive layer. Trace oiri tsvina inotamiswa kubva kumablades zvakare yakaderera mupendero tackiness - ese achiita seanosimudza induces.

Standard End Face Zvinodiwa - Maitiro ekudzivirira Oozing uye Kusimudza

Kudzvanya kunamira kudonhedza uye kusimudza mupendero zvakanyanya, iyo slitting yekupedzisira kumeso inofanirwa kuzadzisa zvinotevera maitiro:

1. Morphology - yakatsetseka uye inotsvedza

• Girazi faibha dzakachekwa zvakachena pasina kuratidzwa.

• Adhesive layer, substrate, uye PTFE coating inoumba yakabatanidzwa flat chikamu.

• Hapana glue tambo, kushomeka kwekunamira, kana delamination.

2. Nguva dzose - yakananga uye yunifomu

• Chiso chekupedzisira chakatwasuka chine kunyorova uye kurerekera.

• Inovimbisa yunifomu yekusagadzikana kwekugovera kana yaiswa mumaromburu.

Chiso chakatsetseka, chakasimba, chisina kukuvara chinoshanda se 'chisimbiso' chematepi edge. Iyo inovhara iyo inonamira layer inopesana nezvinokambaira uye inovimbisa yakakwana yekubatanidza kugona pamwe chete mamirimita ese ekumucheto - kubvisa kuyerera uye kusimudza patsime.

Pfupiso - Kutsemura Hunhu Zvinokanganisa Kuita Kwematepi

Aokai PTFE inoshandisa chaiyo yekutsemura midziyo ine mashizha akapinza uye makona akakwenenzverwa kugadzira tepi micheto yakachena, yakatsetseka, uye isina kuremara. Kana iwe uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinyura kana kusimudzwa nemamwe matepi, kutsemura mhando inogona kunge iri chikonzero. Bata nesu kuti tikurukure nezvechikumbiro chako.
