Paw Akwankyerɛ ma PTFE High-Temperature Tape ma Demolding & Anti-Stick Nnwuma a Injection Molding Mfiri

Jiangsu Aokai New Materials, adwumayɛfo a wɔyɛ PTFE ne fluoroplastic nneɛma, kyɛ paw gyinapɛn ahorow a PTFE ɔhyew kɛse teyp ma demolding ne anti-stick tebea horow wɔ injection molding mfiri.

I. Ɔhyew-Gyina Paw: Fa w’adwene si Ɔhyew a Ɛko Tia Adhesive Layer ne Substrate so

PTFE teyp no wɔ afã abien: substrate (mpɛn pii no fiberglass ntama a wɔde PTFE akata so) ne akyi adhesive. Adhesive layer no taa yɛ adwumayɛ bottleneck.

1. Kɔ so adwumayɛ ɔhyew ≤ 260 ° C (General plastics & fã bi mfiridwuma plastics) .

Nneɛma a wɔde di dwuma: PE, PP, PS, ABS, PVC a ɛyɛ mmerɛw, EVA, ne PA, PBT ne nneɛma afoforo a wɔayɛ ho adwuma wɔ ɔhyew a ɛba fam mu. Wɔkamfo kyerɛ sɛ wɔpaw: Standard fiberglass-reinforced PTFE tape a silicone nhyɛso-sensitive adhesive (PSA). Nsuo a wɔahyɛ ho nyansa: 0.13 mm anaa 0.18 mm, a ɛkari pɛ wɔ conformability ne service durability. Nsɛm atitiriw a ɛsɛ sɛ yɛhyɛ no nsow: Eyi ne adwumayɛ kwan a eye sen biara ma PTFE teapɔn, a ɛda nnuru a ɛgyina pintinn a ɛkyɛn so ne adwumayɛ a wɔayi no adi adi.

2. Kɔ so adwumayɛ ɔhyew 260 ° C ~ 300 ° C (High-ɔhyew mfiridwuma plastics)

Nneɛma a wɔde di dwuma: PC, PA66, POM, PET, PPA a ɛyɛ hyew kɛse, PPO a wɔayɛ no foforo ne nkuku afoforo a wɔde twitwiw nneɛma a ɛyɛ hyew kɛse. Wɔkamfo kyerɛ sɛ wɔpaw: Fiberglass PTFE teyp a wɔde silicone adhesive a ɛko tia ɔhyew a ɛkorɔn ayɛ. Silicone adhesive a ɛyɛ daa no bɛbɔ akwakoraa ntɛmntɛm, ahwere tackiness na agyaw nkae wɔ saa ɔhyew a ɛwɔ yi ase. Ne kɛse a wɔahyɛ ho nyansa: 0.18 mm anaa 0.25 mm. Thicker adhesive ne substrate layers ma ɔhyew buffering a eye ne wear resistance. Si so dua a ɛho hia: Kyerɛ nhyehyɛe ahorow a wɔde nkata so a ɛko tia ɔhyew a ɛboro 280°C bere tenten ma wɔn a wɔde ma no, na hwɛ sɛ ebia ntama no bɛgu nkuku ho fĩ wɔ ɔhyew a ano yɛ den mu anaa.

3. Ntɛm ara na ɔhyew a ɛsen biara 300 ° C ~ 400 ° C (Titiriw a ɛkorɔn-ɔhyew plastics anaa mpɔtam hɔ ɔhyew mmeae)

Nneɛma a wɔde di dwuma: PEEK, LCP, PPS, PEI, titiriw a wohu wɔ baabi a ɛbɛn mmirikatufo nozzles a ɛyɛ hyew ne partial extrusion die heads. Kɔkɔbɔ a ɛfa paw ho: Ntama a wɔde nkata so a wotumi de ho to so biara nni hɔ a ebetumi agyina ɔhyew a ɛkɔ soro yi ano. PTFE teyp biara a wɔde adhesive ayɛ no bedi huammɔ ntɛm ara, ayɛ carbonize na ɛde efĩ aba nneɛma a wɔawie no mu. Ano aduru foforo:

1. PTFE fiberglass ntama a enni adhesive, a wɔde mfiri asiesie denam mold clamping frames, strips anaasɛ ɔhyew a ɛkorɔn structure adhesives (adhesives a ɛnyɛ nhyɛso-te sɛ silicone sealants).

2. Fusible fully fluorinated PFA film tape, a wɔde abata nkuku no ani denam mframa a ɛyɛ hyew welding so. Etumi gyina 260°C a ɛkɔ so ne 300°C a ɛkɔ so bere tiaa bi ano, nanso wontumi mfa nsi ananmu wɔ ɔkwan a ɛyɛ mmerɛw so te sɛ teyp a ɛde ne ho bata ho. Optimized alternative proposal: Wɔ tebea horow a ɛte saa a ɛyɛ hyew kɛse ho no, wɔkamfo nkuku PTFE a wɔde kata so anaa nano ceramic a ɛyɛ hyew a ɛkorɔn a ɛko tia kata so kɛse.

II. Nneɛma a Wɔde Yɛ Nneɛma a Egyina Paw so: Match Wear Resistance, Corrosion Resistance ne Release Ahwehwɛde ahorow

Plastik a wɔabɔ no honam fam ne nnuru mu nneɛma na ɛkyerɛ sɛnea teyp no yɛ adwuma wɔ soro ne sɛnea ɛyɛ den a wɔhwehwɛ.

1. Nneɛma a ɛyɛ tacky kɛse / nkuku a ɛyɛ mmerɛw

Nneɛma a wɔde gyina hɔ ma: EVA, hot melt adhesive, TPE, TPU, PP grade ahorow bi a wɔayɛ mu nsakrae. Nsɛntitiriw a wɔpaw: Paw teapɔn a ɛma nneɛma pii fi mu a PTFE pii wom ne nea wɔde kata so a ɛyɛ den. Fa PTFE sini teyp a ɛho tew (a enni fiberglass a wɔde hyɛ mu den, ahoɔden a ɛtwetwe ade a ɛba fam, ɛfata ma mmeae a nhyɛso kakraa bi na ɛwɔ hɔ nkutoo) anaasɛ fiberglass PTFE teyp a ɛyɛ fɛ a wɔde ahyɛ mu ma koraa no di kan. Surfaces a ɛbɛn PTFE kronkron no de adwumayɛ a ɛkorɔn a ɛko tia dua ma.

2. Glass fiber / mineral ahyɛ mu ma nneɛma a wɔahyɛ no den

Nneɛma a wɔde gyina hɔ ma: Glass fiber a wɔahyɛ no den PA, PP, PBT, calcium carbonate ahyɛ mu ma PP. Ɔkwan a wɔfa so hyɛ: Nsu a ɛsen no yɛ adwuma te sɛ anhwea krataa a ɛyɛ nsu, na ɛporɔw PTFE a wɔde kata so a ɛnyɛ den no ntɛmntɛm; fiberglass substrate a ɛda adi no bɛma adhesion sintɔ aba. Nsɛntitiriw a wɔpaw:

1. Thickness priority: Paw teyp a emu yɛ duru a ɛmma ɛnsɛe a ne kɛse yɛ mm 0.25 anaa nea ɛboro saa.

2. Structural reinforcement: Paw nneɛma a ɛwɔ multi-layer PTFE coating anaasɛ surface hardening treatment mmom sen sɛ wode ade biako a ɛyɛ tratraa bɛkata so.

3. Ɔkwan a wɔfa so de si ananmu: Fa teyp di dwuma sɛ ade a wɔde di dwuma daa ma adwumayɛ tebea horow a ɛtete saa, na hyehyɛ nhwehwɛmu ne nsakrae kyinhyia ahorow bere ne bere mu sen sɛ wubedi ɔsom nkwa nna a ɛtra hɔ daa akyi.

3. Nneɛma a wɔde nneɛma a ɛyɛ hyew anaasɛ ɛma nsuo ka ho

Nneɛma a wɔde gyina hɔ ma: PVC a ɛyɛ den (ɛma HCl fi adi), nnuru a ɛmma ogya ntumi nhyew (brominated, phosphorus-based ogya a ɛmma ogya ntumi ntɔ), fluorinated processing aids. Failure mode: Nsu a ɛtɔ gu fam no sɛe adhesive layer no anaasɛ ɛhyɛn substrate no mu, na ɛde tape blistering ne delamination ba.

1. Nnuru a ɛko tia adhesive: Si so dua sɛ silicone adhesive wɔ inertness a ɛdɔɔso tia acid a ɛyɛ mmerɛw, plasticizers ne precipitate afoforo.

2. Dense substrate: Paw tape a fiberglass a wɔanwene no denneennen ne PTFE impregnation a wɔatoto mu koraa na asiw gas/nsu a ɛbɛkɔ mu a ɛsɛe akyi adhesive no ano.

3. Venting optimization: Fa mould vacuum extraction anaa vent grooves foforo bom sɛ ɛho hia a na ama precipitate a ɛboaboa ano wɔ tape interface no so fi fibea no so atew.

4. Nneɛma a ɛyɛ static-sensitive

Nsɛm a ɛtaa ba: Ɛlektrɔnik afã injection molding, high-flow PP film extrusion. Wɔkamfo kyerɛ sɛ wɔpaw: Anti-static PTFE tape (PTFE tape tuntum a wɔde conductive carbon black anaasɛ anti-static layer soronko akata so) na wɔakwati mfutuma a ɛbɛtwetwe ne electrostatic discharge asiane ahorow.

III. Adaptation a Egyina Nnwinnade ne Dwumadi Ho Nsɛm So

1. Injection nkuku demolding

Cavities, sliders ne lifters: Wɔtaa de teyp gu mmeae a nkuku abata ho. Ɛho hia sɛ teyp a ɛyɛ tratraa a ne kɛse yɛ mm 0.13 a ɛtrɛw yiye na ama atumi afata nneɛma a ɛyɛ den a ɛyɛ kurukuruwa. Kwati ejector pin ne vent slots; yɛ ahwɛyiye wɔ afã horow a ɛyɛ pɛpɛɛpɛ ho efisɛ teyp no mu duru bɛsakra nneɛma a wɔde yɛ nneɛma no nsusuwii a ɛma wotumi gyina ano. Mmirikatu mprɛte a ɛyɛ hyew ne nozzle tips: Ɔhyew a ɛkorɔn yiye na ɛwɔ ha; PTFE ntama a wɔde mfiri ayɛ a enni adhesive nkutoo na wobetumi de adi dwuma de asiw flash adhesion ano. Wɔabara koraa sɛ teyp a ɛde ne ho bata ho.

2. Extruders ne nnwinnade a ɛwɔ nsu ase

Extrusion die anofafa / outlets: Siw melt a ɛboaboa ano ne stringing wɔ discharge port. Paw ultra-thin (0.08 mm–0.13 mm) high-release tape na kwati sɛ wobɛsesa die orifice nsusuwii. Fa teyp no kyekyere teyp no fi anim kosi n’awiei anim wɔ ɔkwan a wɔfa so fi mu no so na ama nsu a ɛreworo so akɔ lap nkwaa mu no so atew. Pelletizer template: Wɔde hyɛ ɔhyew a ɛkorɔn mu a ɛyɛ hyew ne ahwehwɛ nhama a ɛyɛ mmerɛw mu tẽẽ. Teyp a emu yɛ duru a ne kɛse yɛ mm 0.25 anaa nea ɛboro saa yɛ ahyɛde, na wɔhwɛ so sɛ nea wɔde di dwuma daa. Cast film rolls / traction press rolls: Anti-stick na ɛnyɛ den sɛ wobɛhohoro. Wobetumi de silicone-backed PTFE tape abɔ rollers ho, anaasɛ wobetumi agye PTFE fiberglass nsateaa a enni adhesive atom. Hwɛ sɛ teapɔn no hyew a ɛko tia no ne roller no ani hyew hyia sɛ ɔhyew ka ho a.
