PTFE Tape Adhesion vs Tembiricha: Maitiro eKuvandudza

Jiangsu Aokai New Materials, inyanzvi sosi inogadzira yePTFE yakakwirira-tembiricha tepi, inogovera ruzivo rwehunyanzvi kwauri.

PTFE (Teflon) yakakwirira-tembiricha tepi inogona kazhinji kushandiswa kuenderera mukupisa kwe -196 ℃ kusvika 260 ℃ . Mumashandisirwo mazhinji, tembiricha yekupikisa muganho wetepi inorambidzwa neadhesive layer  pane PTFE substrate. Kuita kwayo kunotevera mitemo yakajeka ine chekuita nekushisa:

Adhesive performance inoderera sezvo tembiricha inokwira  Nekuwedzera tembiricha, iyo yekunamatira inopfava zvishoma nezvishoma, inokambaira uye kunyange kuderera, zvichiita kuti kuderedzwa kwakabatana simba. Macroscopically, izvi zvinoratidzira sekudonha kwekubata kunamatira.

Kuita chikumbaridzo chakatemwa nemhando yeadhesive  Different adhesives ane akasiyana zvakanyanya kutadza tembiricha:

 

Kuvandudza iyo yepamusoro-tembiricha yekubata nguva , optimization inonyanya kuitwa kubva kune matatu maficha: adhesive kuumbwa, substrate performance, uye interfacial bonding chimiro.

1. Adhesive Layer: Kuvandudza Weak Link

·  Sarudza yakakwirira-tembiricha inodzivirira adhesive system : Isa pamberi pesilicone pressure sensitive adhesive yenguva refu-yepamusoro-tembiricha yekushanda mamiriro.

Fluorocarbon  shanduko : Shandura silicone adhesive ine fluorocarbon makomisheni kusimudza tembiricha yegirazi (Tg) kusvika 230 ℃. Mushure memaawa makumi mana nemasere ekuenderera mberi kwekushandisa pa260 ℃, mwero wekunamatira wekunamatira uchiri kupfuura 85%.

·  Kusuma crosslinking network : Gadzira nano-scale crosslinking network kuti uwedzere zvakanyanya kusimba kwakabatana uye shear kuramba kweiyo adhesive layer pane yakanyanya tembiricha.

·  Wedzera thermal stabilizers : Batanidza inhindered phenol uye mamwe thermal stabilizers muformula kuti ibudirire inhibit oxidative degradation pasi pekupisa kwakanyanya.

2. Substrate Layer: Simudza iyo yakazara tembiricha yekudzivirira muganho

·  Nano-filler modification : Wedzera nano silica, boron nitride nanotubes uye mamwe nanoparticles muPTFE substrate kuti igadzire yemuviri yekuyambuka mapoinzi. Kupisa kwekupisa tembiricha kunogona kuwedzerwa ne20-30 ℃, uku ichichengetedza pamusoro pe90% yekutanga kunamatira pa260 ℃.

·  Molecular crosslinking treatment : Crosslink PTFE molecular cheni kusimudza kuenderera mberi sevhisi tembiricha kusvika 300 ℃.

:  Kusimbisa Fiber Wedzera 25% girazi faibha kana kabhoni faibha kuti ukwidze zvinokambaira ne300%, zvichiita kuti urambe uchishandiswa kusvika 280 ℃.

3. Interface & Structural Design: Wedzera kugadzikana kwekubatana

·  Substrate surface treatment : Isa mushonga weplasma kana kemikari etching paPTFE kuti uwedzere kushata uye kuita kwepamusoro, kusimbisa kubatana kwechiso uye kudzivirira delamination pakupisa kwakanyanya.

·  Wedzera yepakati barrier layer : Isa polyimide (PI) yekuzviparadzanisa layer pakati pePTFE substrate uye inonamira kuti ivhare adhesive kupinda uye kutama pasi pekushisa kwepamusoro, kuvandudza kugadzikana kwese kwechimiro.

·  Gadzirisa maumbirwo anoumbwa : Adopt multi-layer composite structure: PTFE coating + reinforcing substrate + high-temperature stable layer , kuenzanisa kupisa kwekudzivirira uye kuita kwekunamatira zvakakwana.

·  Chengetedza kupisa kwekuwedzera clearance : Iyo linear yekuwedzera coefficient yePTFE inokwana kagumi pane iyo yesimbi.

Chengetedza gap re 0.15-0.3 mm  mukugadzira dhizaini kuti usunungure kushushikana kwekupisa zvinobudirira.

Izvo zviri pamusoro pehunyanzvi zvemukati zvinopihwa ne Jiangsu Aokai New Materials Technology Co., Ltd.

Kana iwe uchida rumwe ruzivo nezve tekinoroji parameters, mamiriro ekushandisa uye yakagadziridzwa mhinduro kune yedu yakazara chigadzirwa mutsara - kusanganisira PTFE yakakwirira-temperature tepi, PTFE yakakwirira-temperature tepi, PTFE yakakwirira-temperature mesh bhandi, seamless fusing muchina bhandi, single-sided PTFE jira, yakakwirira-tembiricha inodzivirira-inodzivirira girasi bhandi - ndapota inzwa tisingaregi girazi -

Isu tinogara tichinamatira kune bhizinesi uzivi hwehunyanzvi uye kuvimbika, uye tinoyedza kukupa iwe-yekumira maindasitiri mhinduro uye inofunga mushure mekutengesa sevhisi.
