PTFE Mucheka Slitting: Key Points

Senyanzvi yekugadzira PTFE jira rekushisa kwepamusoro, Jiangsu Aokai New Materials anogovera maitiro epakati ekutsemura. Kuti udzivise maburrs, delamination uye dimensional kutsauka panguva yekutsemura, zvakakosha kuti udzore zvakarongeka zvinhu zvina zvakakosha: maturusi ekucheka, zvishandiso, mbishi zvinhu uye tekinoroji yekugadzirisa. Kuregeredza mune chero chinongedzo kunokonzeresa kupera kwechigadzirwa.

I. Core Key Points dzeSlitting process

1. Kusarudzwa uye Kugadziriswa Kwekucheka Zvishandiso

·  Material : Isa pamberi simende carbide (tungsten simbi) kana yakakwirira-kumhanya mablades kukwirira kupinza uye refu sevhisi upenyu.

·  Geometric Shape : Gamuchira maturusi ane positive rake angle kuti ucheke zvinhu zvakachena pane kusvinwa, kudzivirira delamination uye edge burrs.

·  Parameter Setting : Iyo blade clearance inokurudzirwa kuve 5% -10% yehukuru hwezvinhu; kona yekucheka inodiwa 15 ° kusvika 20 °.

2. Equipment Condition uye Precision

·  Tension Control System : Tora matatu-chikamu tension control inosanganisira kusunungura, kudyisa uye kudzosera kumashure kuchengetedza kugadzikana kwakagadzikana mukati mekuita uye kudzivirira kutambanudza kana kusunungura deformation yezvinhu.

·  Deviation Correction System : Tevedzera musimboti wekugadzirisa kururamisa kwekutsauka kutanga, wozogadzirisa mablades kuti uone kuti cutter inofanana neiyo kumucheto kwezvinhu.

·  Kucheka Angle : Chengeta nzira yekucheka perpendicular kune fiber weaving nzira yejira. Kucheka zvisina kujairika kunokonzeresa maburrs uye tambo dzakasununguka.

3. Raw Material State Control

·  Kurapa Kwakazara : Zvigadzirwa zveSemi-zvakapedzwa zvakaputirwa nePTFE emulsion zvichaiswa statically kwemazuva maviri kusvika matatu isati yatsemurwa, kuitira kuti resin inyatsobatana uye kuporesa ne fiberglass substrate.

·  Internal Stress Relief : Mukuona kwezvinokambaira zvinhu zvePTFE, ita pre-annealing kurapwa kubvisa kushushikana kwemukati uye kuvandudza dimensional kugadzikana mukutsemura.

·  Environmental Control : PTFE inonyatso teerera kune tembiricha shanduko. Kuchekwa kuchaitwa mukupisa-kupisa, kunyorova-nguva dzose uye musangano wakachena kudzivirira zvikanganiso zvakakonzerwa nekuwedzera kwekupisa uye kuderera.

4. Slitting Parameter Setting

·  Kucheka Kumhanya : Sanganisa yakakwira yekucheka nekumhanya yakaderera yekudyisa kuvimbisa kushanda zvakanaka kwekugadzira uye kuderedza zvinhu extrusion nemashizha.

·  Kutonhodza uye Kuzora : Ramba uchiisa mhepo yakamanikidzwa kana mvura inotonhorera panguva yekutsemura kutonhora pasi mashizha uye zvinhu, kudzivirira kupfava kunyorova uye maburrs anokonzerwa nekupisa.

II. Targeted Solutions to Common Defects

·  Dzivisa Burrs uye Loose Threads : Chengetedza mashizha akapinza uye chinja nguva dzose; chengetedza vertical kuchekwa kunopesana nekugadzirwa kwejira; nyatso gadzirisa zvinonzwisisika blade clearance.

·  Dzivirira Delamination : Guarantee yakakwana static yekurapa nguva yehafu-yapedzwa zvigadzirwa; shandisa mashizha anopinza pakucheka zvakanaka; sarudza zvigadzirwa zvemhando yepamusoro zvine simba rakasimba rekubatanidza pakati pemachira egadziko uye PTFE coating.

·  Kudzora Dimensional Kutsauka : Isa matatu-chikamu tension control kudzivirira kutambanudza zvinhu; ita annealing stress relief in advance; simbisa kutevedzana kwekushanda uye gadzira munzvimbo inogara tembiricha.

Mukupedzisa, kutsemura kwepamusoro-soro ibasa rakarongeka. Nyatsodzora maturusi, zvishandiso, zvishandiso uye maitiro, uye tora zvakanangwa mhinduro kune zvakajairika hurema, kuitira kuti zvinyatso kuvandudza goho rechigadzirwa.

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

Kana iwe uchida zvakatsanangurwa, zvigadziriso zvemashandisirwo uye masevhisi akajairwa ePTFE tembiricha yakakwira tepi, PTFE yakakwira tembiricha mesh bhandi, isina musono fusing bhandi, single-sided PTFE jira, tembiricha inodzivirira bhandi rekutakura uye tembiricha inodzivirira fiberglass jira, tapota taura nesu:

·  Mr. Guo: +86 18944819998

·  Mr. Liu: +86 13705266308

Isu tinoomerera kune hunyanzvi uye kuvimbika, tichikupa iwe yakavimbika-yekumira maindasitiri zvigadziriso uye masevhisi ane pfungwa.
