Polyurethane Nneɛma a Wɔde Fi Adi Mu

Polyurethane extruded afã horow yɛ nneɛma a wɔabom ayɛ a wɔde polyurethane resin ayɛ sɛ matrix ade na wɔyɛ denam extrusion mfiridwuma so. Nea ɛwɔ mu titiriw ne sɛnea polyurethane yɛ adwuma yiye ne extrusion mfiridwuma a ɛyɛ adwuma yiye a wɔde di dwuma kɛse wɔ nnwuma te sɛ adansi, akwantu, ne mfiri mu no a wɔaka abom.

1.Mfiridwuma mu nneɛma

• Ahoɔden a ɛkorɔn: Tensile ahoɔden taa boro 50MPa, na bending ahoɔden betumi adu 50-75MPa, a ebetumi asi atetesɛm dade ne aluminium nneɛma ananmu.
• Ne mu duru yɛ hare: ne density sua sen dade ne aluminium alloys, ɛwɔ akwantu ne installation ho ka a ɛba fam. ‌

2.Corrosion a ɛko tia

• Acid alkali nkyene: tumi gyina acid, alkali, nkyene ne organic corrosion dodow no ara ano, a ɛfata ma mpoano ne mmeae a ɛhɔ yɛ nwini.
• Ngo a ɛko tia: Ɛtumi gyina ngo ahodoɔ ano yie na ɛfata ma nsɔano te sɛ ngo nsɔano. ‌

3.Insulation ne ɔhyew insulation adwumayɛ

• Ɔhyew a ɛba fam: Ɔhyew a ɛkɔ dan mu no yɛ 0.22W/m • k pɛ, a ɛyɛ bɛyɛ aluminium aduru 1/700 na ɛfata ma nneɛma a wɔde siw mframa ano.
• Low coefficient of linear thermal expansion: Te sɛ ɔfasu ho nneɛma no, ɛnyɛ mmerɛw sɛ wɔbɛma nsonsonoe aba bere a ɔhyew mu nsonsonoe sesa no. ‌

4.Production nhyehyɛe

• Efficient: Extrusion ahoɔhare betumi adu 0.6-2.0m / simma, a ɛyɛ 2-5 mpɛn pii sen atetesɛm composite nneɛma.
• Nneɛma a atwa yɛn ho ahyia ho banbɔ: Adeyɛ kwan no nni solvent-na na ɛdi ahwehwɛdeɛ a ɛwɔ green production mu no so. ‌

5.Application tebea horow

• Architecture: Wɔde yɛ nneɛma te sɛ ɔpon ne mfɛnsere nnua, ntama afasu, ne nea ɛkeka ho, de tew adan mu duru so na ɛma nnyigyei a wɔde siw ano no yɛ adwuma yiye. ‌
• Nneɛma a wɔde fa kar: Wɔyɛ kar ne po so hyɛn mu nneɛma a wɔde bɛtew nipadua mu duru so na wɔatrɛw bere a wɔde yɛ adwuma no mu.
• Nneɛma a wɔde yɛ adwuma: Wɔde di dwuma de boa nneɛma a ɛwɔ abɔnten so ne akwan a wɔfa so fa mu no mu na ama adan no atumi atra hɔ akyɛ.

Polyurethane (PU a wɔatwa no tiawa) yɛ polyurethane plastic bi a ɛwɔ nneɛma pii a mfaso wɔ so, a nea ɛka ho ne sɛ ɛyɛ den, ɛyɛ nea ɛda adi pefee, ɛko tia ngo, ɛko tia srade, ne nea ɛmma ɛnsɛe. Wɔ mfiridwuma mu no, wɔyɛ thermoplastic elastomers a wɔde linear block copolymers a ɛwɔ afã horow a ɛyɛ den ne nea ɛyɛ mmerɛw na ɛyɛe.

Yɛn nneɛma no wɔ su pa, ɛyɛ adwuma yiye, na ne bo yɛ den. Yebetumi ayɛ customize na yɛadi PU injection molded afã horow sɛnea adetɔfo mfonini anaa nhwɛsode ahorow te.

1. Wɔde di dwuma ma mfiridwuma a ɛkorɔn wear resistance, high-pressure sealing ne rɔba nneɛma, te sɛ hydraulic cylinder sealing.

2. Nneɛma ahorow ne nea ɛyɛ den wɔ hɔ a wubetumi apaw bi. Wubetumi de nhwɛsode anaa mfonini ahorow ama yɛn, na yɛde nneɛma a eye sen biara bɛma wo.
