Maitiro Ekudzivirira PTFE Tepi Kutsemuka Pasi Kudzokororwa Kupeta Uye Kuvhura

Mumitsara yekurongedza, michina yekuisa chisimbiso chekupisa, uye michina yekugadzira chikafu, PTFE high-temperature tepi inogara yakakotama, yakavhurwa, uye yakadzvanywa - kutenderera mushure mekutenderera. Nokufamba kwenguva, kunyange iyi yakasimba zvinhu inogona kugadzira mitswe kana kuputsika.

Sei izvi zvichiitika? Mhinduro iri muzvinhu zvitatu: substrate, chinonamira, uye kuti tepi inoiswa sei.

PaAokai PTFE , takaongorora mazana ekukundikana kwemunda. Ichi chinyorwa chinogovera matipi anoshanda ekuwedzera hupenyu hwematepi uye kudzivirira kutsemuka nguva isati yakwana.

Simbisa Chimiro - Substrate uye Ukobvu

Iyo substrate inoshanda senge dhizaini, yakanyatso tarisa kukotama kuramba uye kubvarura simba.

Yakachena PTFE firimu inoratidzira yakanaka kuchinjika asi isina kukwana mechini simba - inowanzoitika kubvaruka pasi pekunetsekana kwakadzokororwa. Girazi faibha yakasimbisa PTFE inonatsiridza zvakanyanya simba rekusimba, kuramba kubvarura, uye kukambaira kuramba, zvichiita kuti ive sarudzo inosarudzika yezviitiko zvekukotama.

Hukobvu hwakakoshawo. 0.13mm inoshanda semutsara wekuparadzanisa. Matepi akatetepa kupfuura 0.13mm anochinjika asi akaderera musimba, ari nyore kugadzira ma microcracks pasi pekudzvinyirirwa kwakadzokororwa uye kutambanudza.

Kurudziro : Kune akawanda ane simba emidziyo, 0.18mm ukobvu negirazi fiber kusimbisa ndiyo yakajairika sarudzo.

Mumashandisirwo epamusoro-soro akadai seanoenderera mberi mabhendi sealers (achishanda pa 30-60 kutenderera paminiti), iyo yekupeta radius yetepi yakatenderedza chinhu chekudziya chinhu chakakosha dhizaini dhizaini. Radhiyasi yekupeta idiki pane 5mm inowedzera kushushikana kwenzvimbo nepamusoro pe300% zvichienzaniswa neredhiyo ye15mm, zvinokurumidzisa kutangwa kwekutsemuka. Kune yakadaro tight-radius application, kushandisa girazi faibha yakasimbisa PTFE tepi ine yakarukwa kuvaka (panzvimbo yefirimu-based tepi) inogona kuwedzera flex life by 5-10 times. Pamusoro pezvo, matepi ane kutsetseka kwemashure kupedzisa anogadzira kushoma kwemukati panguva yekukotama, zvichiwedzera kudzikisira kuneta. Mashoko emumunda anoratidza kuti kuchinja kubva pa 0.10mm yakachena PTFE firimu tepi kuenda kune 0.18mm girazi fiber reinforced tepi inowedzera hupenyu hwebasa kubva kumasvondo maviri kusvika kumwedzi mitanhatu mumidziyo yekuisa chisimbiso chepamusoro-frequency.

Sarudza Right Adhesive

Iyo yakanamatira inobatanidza tepi kune midziyo - chinhu chinokosha chinokanganisa hupenyu hwebasa rakasimba. Silicone pressure-sensitive adhesive ndiyo yakanakisa sarudzo kune inosimba yepamusoro-tembiricha nharaunda.

Nei silicone ichihwina pakukotama maapplication:

• Inomira yakadzokororwa kukotama uye kudedera pasina kuputika

• Inochinjika kukuchinjana kunopisa nekutonhora

• Inochengetedza kunamatira kunyangwe mushure mezviuru zvema flex cycle

Aokai PTFE 's in-house test inoratidza kuti silicone adhesive matepi anochengetedza anopfuura makumi mapfumbamwe muzana esimba rawo rekutanga masvuura mushure me10,000 kubhenda kutenderera, nepo acrylic-based matepi anorasikirwa anosvika makumi mashanu muzana mukati me5,000 mitsetse. Pamidziyo inoshanda maawa gumi nematanhatu zuva nezuva, musiyano uyu unoshandura kumwedzi yekuwedzera sevhisi hupenyu.

Kune matepi ePTFE anoshandiswa pamabhawa ekuvharisa anodzokerana (semuenzaniso, vertical form kuzadza michina yechisimbiso), iyo inonamira inofanirawo kuramba 'inotonhora kuyerera' - zvishoma nezvishoma deformation pasi pekumanikidzwa. Yakashata-yemhando yesilicone adhesives inogona kusvina kubva pasi petepi mupendero mushure mekushandiswa kwenguva refu, zvichikonzera zvakasara zvekunamira pachigadzirwa kana yekuisa chisimbiso. High crosslink-density silicone adhesives ine thermosetting chimiro inochengetedza kugadzikana kwedimensional kunyangwe pa250 ° C. Paunenge uchisarudza tepi yePTFE yemhando yepamusoro-frequency bending applications, kumbira data pa'shear adhesion failure temperature' (SAFT) uye 'holding power' - values ​​above 260°C and over 24 hours at 200°C zvinoratidza robust adhesive system.

Kuisa Kwazvo uye Kugadzirisa Kwehupenyu Hurefu

Zvigadzirwa zvePrimiyamu zvinounza kuita kwakaringana chete nekushandisa kwakaringana uye kugadzirisa.

Kurapwa Kwepamusoro Usati Waiswa
Panzvimbo yemidziyo yakachena uye yakaoma ine anhydrous ethanol kana isopropanol. Oiri mavara, guruva, uye mwando zvinonetesa kunamatira uye zvinokonzeresa kupeuka kwekutanga. Shandisa 800-1000 grit yakanaka sandpaper kukwenenzvera zvinyoro nyoro nzvimbo dzesimbi - izvi zvinokwidziridza kupindirana kwemichina uye kunamira kunamira.

Tension-Yemahara Kuisirwa uye Edge Reinforcement
Isa tepi zvakasununguka pasina kutambanudza. Tensile stress inotungamira mukudzikira uye warping panguva yekupisa bhasikoro. Dzvanya zvakaenzana kubva pakati kuenda kumativi ese ane scraper kubvisa mabhubhu emhepo. Simbisa uye sunga mipendero - kana shandisa yakakwirira-tembiricha inodzivirira silicone sealant - kudzivirira kusimudza kumucheto.

Working Condition Adjustment

• Chengetedza tembiricha yekushanda iri pasi pe260 ° C - iyo yakareba muganhu wesilicone adhesive

• Dzivisa kupisa kwenzvimbo (nzvimbo dzinopisa)

• Dzivirira yakawandisa mechanical pressure inogona kupwanya tepi

• Chengetedza nharaunda yakachena kuderedza abrasion kubva kuguruva nesimbi zvidimbu

Kugara Kuongorora uye Nenguva Replacement
PTFE tepi chikamu chinodyiwa mukushanda kwakasimba. Chitsive nekukasika kana chimwe cheizvi chaonekwa:

• Edge warping kana kusimudza

• Carbonization, yellowing, kana scorch marks

• Kukundikana kwekunamatira, kufashukira, kana kutama

• Inooneka abrasion, microcracks, kana pinholes

Pfupiso - Makiyi ekutora ekudzivirira Tepi Kutsemuka

Muchidimbu , kudzivirira kutsemuka uye kutsemuka kwePTFE yakakwirira-tembiricha tepi pasi pekukotama yakadzokororwa inodzika kusvika kune matatu sarudzo: girazi fiber reinforced substrate, 0.18mm ukobvu (kana yakakodzera mutoro wako), uye silicone adhesive. Kuisirwa kwakaringana - kwakachena nzvimbo, pasina kushushikana, kumucheto kusimbisa - kunowedzera kaviri hupenyu hunoshanda.

Kune ma-high-cycle applications (sealers, presses, conveyors with tight radii), funga girazi rakarukwa fiber reinforced giredhi uye ongorora pamwedzi kune microcracks.
