PTFE Ntama a Wɔpaapae Mu: Nsɛntitiriw

Sɛ́ adwumayɛfo a wɔyɛ PTFE ntama a ɛyɛ hyew kɛse no, Jiangsu Aokai New Materials kyɛ akwan titiriw a wɔfa so slitting. Sɛnea ɛbɛyɛ a wɔbɛkwati burrs, delamination ne dimensional deviation bere a wɔrepaapae mu no, ɛho hia sɛ wodi nneɛma atitiriw anan so wɔ nhyehyɛe kwan so: nnwinnade a wɔde twa, nnwinnade, nneɛma a wɔde yɛ adwuma ne mfiridwuma a wɔde yɛ adwuma. Anibiannaso a wɔbɛyɛ wɔ link biara mu no bɛma nneɛma a wɔawie no asɛe.

I. Nsɛntitiriw Titiriw a Ɛfa Slitting Process Ho

1. Nnwinnade a Wɔde Twitwa Nneɛma a Wɔpaw ne Nsiesiei

·  Nneɛma : Fa cemented carbide (tungsten dade) anaa dade nhama a ɛde ahoɔhare kɛse di kan ma ɛyɛ nnam kɛse na ɛyɛ adwuma tenten.

·  Geometric Shape : Fa nnwinnade a rake angle pa wɔ so twa ade no yiye sen sɛ wobɛpiapia no, sɛnea ɛbɛyɛ a worennya delamination ne edge burrs.

·  Parameter Setting : Wɔkamfo kyerɛ sɛ blade clearance no nyɛ 5%-10% wɔ nneɛma no mu duru mu; nea ɛyɛ papa sɛ nea wɔde twa no yɛ 15° kosi 20°.

2. Nnwinnade Tebea ne Pɛpɛɛpɛ

·  Tension Control System : Fa afã abiɛsa tension control a unwinding, aduan ne rewinding ka ho na ama nhyɛso a ɛyɛ den wɔ adeyɛ no nyinaa mu na asiw nneɛma a ɛtrɛw anaasɛ ɛyɛ loose deformation ano.

·  Deviation Correction System : Di nnyinasosɛm a ɛne sɛ wobɛsesa deviation correction kan no akyi, afei woasiesie blades de ahwɛ ahu sɛ cutter no ne ade no ano hyia.

·  Cutting Angle : Ma kwan a wɔfa so twa no nkɔ tẽẽ ne ntama no kwan a wɔfa so nwene nhama no. Ɛnyɛ den sɛ sɛ wotwa no kwa a, ɛbɛma anoano ayɛ mmerɛw na nhama ayɛ mmerɛw.

3. Raw Material Ɔman Nhyɛso

·  Full Curing : Wɔde nneɛma a wɔawie fã bi a wɔde PTFE emulsion akata so no si hɔ wɔ baabiara nnafua 2 kosi 3 ansa na wɔapaapae mu, sɛnea ɛbɛyɛ a resin betumi ayɛ biako koraa na wɔde fiberglass substrate ayɛ no aduru.

·  Internal Stress Relief : Esiane sɛ PTFE nneɛma no creep su nti, yɛ pre-annealing treatment de yi emu nhyɛso fi hɔ na ɛma dimensional stability tu mpɔn wɔ slitting mu.

·  Nneɛma a Atwa Yɛn Ho Ahyia Sohwɛ : PTFE yɛ nea ɛyɛ mmerɛw kɛse wɔ ɔhyew mu nsakrae ho. Ɛsɛ sɛ wɔyɛ slitting wɔ adwumayɛbea a ɛhɔ yɛ hyew daa, ɛhɔ yɛ nwini daa na ɛho tew na wɔakwati mfomso a ɛba pɛpɛɛpɛ a ɛnam ɔhyew a ɛtrɛw ne nea ɛtwetwe so ba.

4. Slitting Parameter Nsiesiei

·  Twitwa Ahoɔhare : Fa ahoɔhare a ɛkɔ soro a wɔde twa ne ahoɔhare a ɛba fam a wɔde ma aduan bom na ama woanya awerɛhyem sɛ wɔbɛyɛ no yiye na woatew nneɛma a wɔde fi mu denam nhama so no so.

·  Cooling and Lubrication : Kɔ so fa mframa a wɔahyɛ no den anaa nsu a ɛma onwini gu so bere a worepaapae mu no na ama nhama ne nneɛma no ayɛ nwini, na amma coating no ayɛ mmerɛw ne burrs a efi ɔhyew a ɛboro so de ba no ano.

II. Mfomso Ahorow a Ɛtaa Ba Ho Ano Aduru a Wɔde Si Hɔ

·  Kwati Burrs ne Loose Threads : Ma blades no nyɛ nnam na sesa daa; hwɛ hu sɛ wobɛtwa no gyina hɔ atia ntama no nwene; pɛpɛɛpɛyɛ nsakrae a ntease wom blade clearance.

·  Siw Delamination ano : Guarantee bere a ɛdɔɔso a ɛbɛma static curing bere ama semi-finished nneɛma; fa nhama a ano yɛ nnam di dwuma de twitwa nneɛma yiye; paw raw materials a ɛfata a ɛwɔ bonding force a emu yɛ den wɔ base fabric ne PTFE coating ntam.

·  Control Dimensional Deviation : Fa afã abiɛsa tension control di dwuma na woakwati nneɛma a ɛtrɛw; di kan yɛ annealing stress relief; standardize adwumayɛ nnidiso nnidiso ne nhyehyɛe wɔ daa ɔhyew tebea mu.

Sɛ yɛde rewie a, slitting a ɛyɛ pɛpɛɛpɛ kɛse yɛ adwuma a wɔayɛ no nhyehyɛe. Di nnwinnade, nnwinnade, nneɛma ne akwan horow so yiye, na fa ano aduru a wɔde asi wɔn ani so di sintɔ ahorow a ɛtaa ba ho, sɛnea ɛbɛyɛ a wobɛma nneɛma a wonya no atu mpɔn yiye.

Atifi hɔ nsɛm no yɛ nea wɔde ama Jiangsu Aokai Nneɛma Foforo Mfiridwuma Co., Ltd.

Sɛ wuhia nsɛm a ɛkɔ akyiri, application ano aduru ne customized services ma PTFE ɔhyew a ɛkorɔn ntama, PTFE ɔhyew kɛse teapɔn, PTFE ɔhyew a ɛkorɔn mesh abɔso, seamless fusing abɔso, biako-afã PTFE ntama, ɔhyew a ɛkorɔn a ɛko tia conveyor belt ne ɔhyew a ɛkorɔn a ɛko tia fiberglass ntama, yɛsrɛ wo, di yɛn ho nkɔmmɔ:
