Dɛn Nti na PTFE Ntama Nni Flex Resistance a Ɛnyɛ Yie?

Nea ɛde ba no ntini ne fiberglass substrate , na ɛnyɛ PTFE a wɔde kata so no.

1. Fiberglass – ɛyɛ den nanso ɛyɛ mmerɛw

Nneɛma Titiriw a Ɛka Flex Resistance

1. Thickness – ade a ɛho hia sen biara

Mmara a ɛfata: Ntama a ɛyɛ tratraa no flex yiye. Wɔ dwumadie a ɛhia sɛ wɔkotow mpɛn pii no, kyerɛ grade a ɛyɛ tratraa a ɛdi w’ahiadeɛ foforɔ ho dwuma (ahoɔden, ɔhyeɛ).

2. Nwene adansi

• Satin weave – floats atenten ma asaawa no twetwe kakra, na ɛkyekyɛ bending stress. Flex nkwa a eye sen plain weave.

• Plain weave – nsɛntitiriw a ɛyɛ den a ɛka bom no lock yarns; adwennwen kɔ so wɔ mmeae a nhyiam ahorow. Worse flex ahoɔden a ɛko tia.

3. Ɔhyew a wɔde yɛ adwuma

Wɔ ɔhyew a ɛkɔ soro (200-260°C) mu no, PTFE a wɔde kata so no yɛ mmerɛw, na fiberglass mfiri ahoɔden so tew. Eyi ma flex fatigue resistance no yɛ kɛse bio. Sɛ wo dwumadie no fa ɔhyew a ano yɛ den ne wo taa kotow nyinaa ho a, hwɛ kwan sɛ ɛbɛkyɛ.

4. Bending radius a ɛwɔ hɔ

Radius kɛse = nkwa tenten. Sharp creasing (radius <1mm) ma folds a awu a fiber bubu ntɛm ara. Sɛ wopɛ akwankyerɛ rollers a, fa diameter a ɛso sen biara a mfaso wɔ so di dwuma. Sɛ́ akwankyerɛ a ɛyɛ den no, roller diameter a wɔkamfo kyerɛ a ɛba fam koraa ne ntama no kɛse 10-20x.

• Tension belts a ɛkyekyere pulley nketewa ho

• Demolding conveyor belts a ɛdannan nnam

Wowɔ akwan abiɛsa a wubetumi afa so:

1. Ɔkwan 1 – Yɛ PTFE ntama a wɔpaw no yiye wɔ ne anohyeto mu

• Paw nea ɛyɛ tratraa (0.08mm kosi 0.13mm) sen nea emu yɛ duru

• Gye PTFE ntama tom sɛ nea wɔde di dwuma – nhyehyɛe ma bere ne bere mu sɛ wobɛsesa (asram kakraa biara a egyina kyinhyia dodow so) .

2. Ɔkwan 2 – Dan kɔ PTFE sini a ɛyɛ den so

Pure PTFE film (skived) wɔ soronko flex ahoɔden. Nanso, enni fiberglass a wɔde hyɛ mu den no, enti ahoɔden a ɛtwetwe no sua na ɛnyɛ den sɛ ɛbɛtetew wɔ nhyɛso ase. Ɛfata ma hare-adwuma, low-tension bending applications.

3. Ɔkwan 3 – Fa aramid anaa ntama foforo a ɛyɛ organic fiber di dwuma

Aramid (sɛ nhwɛso no, Nomex) anaa PPS ntama a wɔde PTFE akata so no ma nkwa nna a ɛyɛ flex sen PTFE ntama a egyina ahwehwɛ so. Aguadi-off: ɔhyew a ɛkɔ so a ɛko tia (mpɛn pii no ≤200°C) ne soro su ahorow a ɛba fam. Sɛ wopɛ sɛ wode di dwuma wɔ 200°C ase a wɔkotow denneennen a, susuw akwan foforo yi ho.

Aokai PTFE yɛ aramid ntama a wɔde PTFE akata so bere a wɔabisa no. Di yɛn ho nkɔmmɔ na woanya ɔhyew ne flex data.

Nsɛm a Wɔaboaboa Ano – Hu Anohyeto Ahorow, Yɛ Nneɛma a Ɛfata
