Maitiro ekuvandudza iyo yakadzokororwa Adhesion Performance yePTFE High-Temperature Adhesive Tapes

PTFE high-temperature tepi inowanzo shandiswa muzvishandiso apo inofanirwa kubviswa uye kuiswazve kakawanda - pane zvinovhara kupisa panguva yekuchinja, pamibhedha yeprinta ye3D, kana sevhavha yenguva pfupi mugungano remagetsi. Zvisinei, mushure memazuva mashoma, matepi akawanda anorasika, anosiya zvisaririra, kana kutadza kubatana.

Nhau dzakanaka: reusability inogona kuvandudzwa zvakanyanya kuburikidza neakarongedzerwa kukwidziridzwa pamativi mana: inonamira yekugadzira , substrate kurapwa , kuseri kwekupfeka dhizaini , uye kushanda kwakakodzera & kugadzirisa..

Aokai PTFE yakagadzira reusable PTFE matepi vachishandisa masimboti aya. Gwaro rino rinotsanangura chidimbu chimwe nechimwe zvakadzama.

Adhesive Formulation Optimization - Iyo Core Factor

Iyo yekunamatira pachayo ndiyo yekutanga determinant reusability. Nzira ina dzekugadzira dzinovandudza kudzokorora kunamatira kushanda.

1. Kuvandudza simba rakabatana uye crosslink density

Gamuchira yakakwira-polymerization-degree silicone gum uye uwedzere kuyambuka masaiti kushandura iyo inonamira layer kuita elastic yakasimba. Izvi zvinodzivirira kubvarura kana kunamira kuchinjisa panguva yekudzokororwa kupepeta uye kunoderedza kuzvirasikirwa kweiyo glue layer. A well-crosslinked adhesive peels zvakachena pane kupatsanura mukati.

2. Low silicone migration formula

Shandisa platinum-catalyzed kuwedzera kurapa system uye nyatsobvisa yakaderera-molecular-uremu zvinhu. Izvi zvinodzivirira kubuda kwediki-morekuru silikoni mafuta inosvibisa inonamira pamusoro uye inodzivirira inoenderera viscosity attenuation. Low-migration adhesives anochengetedza tack yavo yepakutanga pamusoro pematenderedzwa mazhinji.

3. Microphase chimiro chekugadzirisa zvakare kunamatira

Wedzera MQ silicone resin kana gadzira inopindirana yepolymer network kugadzira yakaoma chikamu-chinyoro chikamu microphase kupatsanurwa :

• Zvikamu zvakaoma - zvinopa kubatana kuramba zvakasara glue kutamiswa

• Zvikamu zvakapfava - zvinopa tackiness

Chikamu che viscosity chinogona kudzoserwa mushure mekupukuta guruva pamusoro. Iyi 'repositionable' maitiro akanakira maapplication anoda kugadziridzwa kwakawanda panguva yekubatanidza.

4. Mvura-yekushambidza inodzoreredzwa yakagadziridzwa adhesive

Mushure mekunge iyo inonamira pamusoro yasvibiswa neguruva, iyi yakagadziridzwa silicone adhesive inogona kusukwa nemvura yakachena kana munyoro solvent, ichiwanazve pamusoro pe90% yetangi yayo yekutanga mushure mekuoma. Izvi zvakanyanya kukosha pakuchenesa imba kana zvemagetsi application uko kusvibiswa kusingadzivisike.

Simbisa Simba Rokumisa Pakati pePTFE Substrate uye Adhesive Layer

PTFE inoratidzira Ultra-yakaderera pamusoro pesimba (18-20 dynes/cm), izvo nyore zvinokonzeresa yakazara inonamira kuchinjika - iyo yese yekunamatira layer inosimudza kubva kumashure - pasina kurapwa kwakatsaurirwa.

1. Substrate pamusoro activation

Ita kemikari etching nesodium-naphthalene yakaoma kana plasma kurapwa paPTFE fiberglass jira kuti uunze mapoka epolar akadai seC=O uye -OH, zvichiita kuti makemikari abatanidzwe kana akasimba mechanical interlocking pakati pekunamatira uye substrate. Izvi zvinodzivirira kunamira kubva pakusvuura tsigiro panguva yekubvisa.

2. Specialized primer coating

Isa reactive primer usati wanamatira coating kuti uvake kemikari zambuko pakati pePTFE nesilicone adhesive, kubvisa kutadza kumisa zvachose. Iyo primer inoshanda senge molecular link, inosungirirana kune ese akaitwa PTFE pamusoro uye iyo silicone PSA.

Aokai PTFE inoshandisa proprietary primer system inova nechokwadi chekuti zero inonamira kuendesa kune inotsigirwa kunyangwe mushure megumi + kutenderera kutenderera.

Kuseri (Release Surface) Kurapa Kugadziriswa

Iyo PTFE yekumashure inoburitsa kuburitsa kuita, asi inodzokororwa mhepo uye kusunungura ichiri kukuvadza inonamira pamusoro kuburikidza nekukwenya uye micro-kubvaruka.

1. Enhanced kusunungurwa performance back coating

Isa imwe yakakwira-crosslink-density fluorosilicone kana silicone yekuburitsa layer pane PTFE kumashure. Iyo inochengetedza yakagadzikana yekusunungura simba pasi pekushisa kwepamusoro uye kwenguva refu kudzvanywa, kudzivirira pamusoro pefiber kudhonza uye kukuvadza kune inonamira layer isati yashandiswa zvakare.

2. Embossed kana micro-yakarongeka kumashure

Deredza iyo chaiyo yekubata nzvimbo pakati peiyo kumashure layer uye inonamira pamusoro, ichidzikisa pakarepo inoparadza simba pane glue panguva yekupepeta. Iyi micro-textured surface inoderedza 'stick-slip' mhedzisiro inogona kubvarura chinonamira.

Mashandiro uye Maintenance Guidelines

Kunyangwe tepi yakanyatsogadzirwa inokundikana nekukurumidza kana ikabatwa zvisina kunaka. Maitiro akakodzera anowedzera reusability zvakanyanya.

1. Active kuchenesa kweadhesive pamusoro

Viscosity kuderera kunonyanya kukonzerwa nekusvibiswa kweguruva. Pukuta pasi zvinyoro-nyoro mune imwe nzira nejira risina guruva rakanyikwa mumvura yakachena kana anhydrous doro, ipapo mhepo-yakaoma zvakasikwa kana nemhepo inotonhora - tackiness ichapora zvinoshamisa. Nguva dzose kuchenesa pakati pekushandisa ndiyo imwe chete inonyanya kushanda yekugadzirisa chiito.

2. Dzivisa kukanganisa pasi pemamiriro ekushanda zvakanyanya

• Peel zvishoma nezvishoma pane diki peeling angle (pedyo ne180 °) kuderedza njodzi dzekutadza kwakabatana.

• Usashandise pamusoro petembiricha yakayerwa - iyo yekunamatira ichachembera uye kuoma, ichirasikirwa reusability.

• Chenesa nzvimbo yekunamatira zvisati zvaitika - mavara emafuta anokurumidza kusvibisa dhizaini yekunamatira uye haigone kubviswa zvizere.

3. Bvisa mabhubhu emhepo panguva yelamination

Guruva rinowanzo kuungana kumativi e-bubble edges uye kukonzeresa kushushikana kwenzvimbo, kukurumidza kunamira kuchembera. Yakakodzera bubble-isina application (uchishandisa squeegee kana roller) inowedzera hupenyu hwe tepi inogona kushandiswa zvakare.

Pfupiso - Zviyero zvina zveReusability Improvement

Aokai PTFE inogadzira matepi ePTFE akagadziridzwa kuti adzokorore kunamatira. Magiredhi edu anogezeswa nemvura anogona kupora> 90% tack mushure mekuchenesa, uye yedu primer system inovimbisa zero adhesive kutamiswa. Bata isu kune zvigadzirwa kurudziro uye kutenderera bvunzo data.

Iri gwaro rehunyanzvi rinopihwa ne Jiangsu Aokai New Material Technology Co., Ltd.

Kana iwe uchida kudzidza zvakadzama zvinotsanangurwa, mamiriro ekushandisa uye zvigadziriso zvakagadziridzwa zvechigadzirwa chedu chizere, zvinosanganisira PTFE yakakwirira-tembiricha machira, PTFE yakakwirira-temperature adhesive matepi, PTFE mesh conveyor mabhandi, seamless fusing muchina mabhandi, single-sided PTFE coated jira, heat-resistant bhandi, faibha-inodzivirira bhandi regirazi kuburikidza nemachaneli ari pasi apa:
