PTFE Yepamusoro-Tembiricha Mucheka: Sei Ichipeta Zvisina kunaka uye Zvaunogona Kuita

Kana wakambopeta chimedu che PTFE-yakavharwa fiberglass jira zvinopinza, iwe pamwe wakaona chena crease mutsara uchionekwa ipapo ipapo. Peta zvakare panzvimbo imwe chete, uye jira rinogona kubvaruka.

Uku hakusi kukanganisa - ndiwo maitiro echisikigo ezvinyorwa. PTFE high-temperature jira rinokunda pakudzivisa kupisa, makemikari, uye kunamatira, asi flex resistance (kudzokororwa kupeta kutsungirira) ndiyo pfuma yayo isina simba.

Aokai PTFE yakaedza hupenyu hwekuchinja mukati mehukobvu hwakawanda uye machira. Ichi chinyorwa chinotsanangura chikonzero nei jira racho richipeta zvisina kunaka, richirienzanisa nezvimwe zvinhu, uye rinopa nzira dzinoshanda dzekushanda zvakatenderedza.

Sei PTFE Mucheka Uine Hurombo Flex Resistance?

Chikonzero chikuru ndeye fiberglass substrate , kwete iyo PTFE coating.

1. Fiberglass - yakasimba asi ine brittle

Girazi faibha dzine simba rakanyanya kusimba asi yakadzikira kureba panguva yekuzorora (kazhinji 2-4%). Kana yakapetwa kakawanda, filaments yega yega inoneta uye inotsemuka. Pane imwe nguva fiber shomanana inoputika, kushungurudzika kunotarisa kune zvakasara, zvichiita kuti kukurumidza kupararira - jira rinobvarura nyore nyore.

2. PTFE coating - shoma buffer

Iyo PTFE layer inozora tambo dzefiber, kuderedza kukweshera kwemukati uye zvishoma kuvandudza pliability. Zvisinei, haigoni kubvisa brittleness yegirazi. Inongononotsa kuputika kwefiber nechikamu chidiki.

Inofananidzwa Sei Nezvimwe Zvishandiso?

Kiyi yekutora: PTFE-yakavharidzirwa fiberglass inogara pakati-kudzika-kumucheto pakati pemachira ekupisa epamusoro-soro ekudzivirira kuchinjika. Zviri nani pane girazi risina chinhu asi zvakanyanyisa kudarika firimu rePTFE rakachena.

Zvinhu Zvikuru Zvinokanganisa Flex Resistance

1. Hukobvu - chinhu chinonyanya kukosha

Mutemo wechigunwe: Machira matete anochinjika zvirinani. Kune maapplication anoda kudzokororwa kukotama, tsanangura iyo thinnest giredhi inosangana nezvimwe zvaunoda (simba, tembiricha).

2. Weave kuvaka

• Satin weave - yakareba inoyangarara inobvumira tambo kuti itsvedze zvishoma, ichigovera kubhenda kunetseka. Upenyu huri nani hwekuchinjika pane rukarukwa.

• Plain weave - tight interlacing points kukiya shinda; kushushikana kunonangana pamharadzano. Yakaipisisa flex resistance.

3. Kushanda tembiricha

Pakupisa kwepamusoro (200-260 ° C), iyo PTFE coating inopfava, uye fiberglass mechanical simba inoderera. Izvi zvinowedzera kuwedzera flex fatigue resistance. Kana application yako ichisanganisira kupisa kwakanyanya uye kugara uchikotama, tarisira hupenyu hupfupi.

4. Kupeta radius

Radhiyasi yakakura = hupenyu hurefu. Yakapinza creasing (radius <1mm) inogadzira mapete akafa nekupwanya kwepakarepo fiber. Kune ekutungamira rollers, shandisa yakakura inoshanda dhayamita. Segwara rakakasharara, iyo shoma yakakurudzirwa roller dhayamita ndeye 10-20x ukobvu hwejira.

Yemukati bvunzo data (Aokai PTFE) : Ye 0.13mm satin weave jira, kukotama pamusoro pe10mm mandrel yakawana 500-800 macycle isati yatanga kutsemuka. Kupfuura 5mm mandrel, mitsetse yakadonha kusvika 100-150. Kupfuura 2mm mandrel (yakapinza crease), kukundikana kwakaitika mukati memakumi maviri kutenderera.

Zvinoshanda Zvinokurudzira

Kana midziyo yako ichida kugara uchipeta-peta - senge:

• High-frequency welder drive mabhandi

• Mabhandi ekumanikidza anoputira mabhururu madiki

• Demolding conveyor mabhandi ane majana akapinza

Une sarudzo nhatu:

1. Sarudzo 1 - Optimize PTFE machira kusarudzwa mukati memiganhu yayo

• Sarudza mamakisi akatetepa (0.08mm kusvika 0.13mm) pane anorema

• Kufarira satin weave pane plain weave

• Kumbira MIT flex test data kubva kumutengesi wako (ASTM D2176 kana zvakafanana)

• Dhizaini yakakura yekubhenda radii mumuchina dhizaini

• Gamuchira PTFE jira sechinhu chinodyiwa - ronga nguva nenguva kutsiva (mwedzi mishoma yega yega zvichienderana nekutenderera kuverenga)

2. Sarudzo 2 - Chinja kune yakasimba PTFE firimu

Yakachena PTFE firimu (skived) ine yakasarudzika flex kuramba. Nekudaro, inoshaya iyo fiberglass yekusimbisa, saka ine yakaderera kusimba simba uye kubvarura zviri nyore pasi pekunetsekana. Inokodzera chiedza-basa, pasi-tension bending applications.

3. Sarudzo 3 - Shandisa aramid kana imwe organic fiber jira

Aramid (semuenzaniso, Nomex) kana jira rePPS rakaputirwa nePTFE rinopa hupenyu huri nani huri nani pane girazi-based PTFE jira. Kutengeserana-kure: kuderera kunoramba kuchipisa kupisa (kazhinji ≤200 ° C) uye zvakasiyana pamusoro pezvinhu. Pazvishandiso zviri pasi pe200°C zvine kukotama kunorema, funga nezvedzimwe nzira idzi.

Aokai PTFE inogadzira PTFE-yakavharidzirwa aramid jira pakukumbira. Bata isu tembiricha uye flex data.

Pfupiso - Ziva Miganhu, Dhizaina Zvinoenderana

PTFE high-temperature jira rinomira zvakanaka rinopesana netension, kupisa kwakanyanya (260 ° C), uye kurwisa kwemakemikari. Asi kutadza kwayo kuchinjika kuramba ndicho chinomanikidza chaicho. Iyo haigone kumira yakapinza yakadzokororwa kupeta semabhandi erabha kana yakachena PTFE firimu.

Ishandise apo kukotama kwakapfava kana kusingawanzoitiki.
Kunopinza kana kupeta nguva zhinji kusingadzivisike, ita mutete, shandisa satin weave, wedzera kubhenda radius, kana chinja zvinhu.

Aokai PTFE inopa flex test data kune ese machira edu mamakisi. Isu tinogona kukubatsira iwe kusarudza iko kukora uye kuruka kune yako application yekupeta zvinoda.

Zvemukati zvehunyanzvi zvinopihwa ne Jiangsu Aokai New Materials Technology Co., Ltd.

Kuti uwane zvakatsanangurwa uye zvigadziriso zvetsika zvePTFE high-tembiricha jira, tepi, mesh bhandi, fusing bhandi, nezvimwe:
