I. Endothermic Ɔhyew Porɔw a Etu mpɔn a Wɔde Kɔma Ɔhyew Adesoa Kɛse

1. Endothermic Depolymerization Adeyɛ a Ɛyɛ Den

PTFE (Polytetrafluoroethylene) fi ase porɔw wɔ bɛyɛ 400 °C. Esiane sɛ ɛkame ayɛ sɛ mframa a ɛhyew a ɛyɛ 3,000 °C fi engine ahorow mu ba nti, ɛyɛ depolymerization ntɛmntɛm ma ɛbɛyɛ tetrafluoroethylene monomers. Saa nnuru a ɛka bom a ɛpaapae yi yɛ endothermic adeyɛ a ɛkorɔn. Nneɛma kilogram biara twetwe ɔhyew kɛse, na ɛdan ɔhyew ahoɔden a ɛwɔ ɔhyew a ɛkɔ soro mu ma ɛbɛyɛ mframa ahoɔden a ɛwɔ mu na ɛma ɔhyew fi ɔfasu no ani yiye.

2. Siw Ɔhyew a Ɛkɔ Ɔdan no Mu no Siw

Sɛnea Jiangsu hwehwɛɛ mu no PTFE ntama a ɛyɛ hyew kɛse , saa phase nsakrae ne endothermic decomposition nhyehyɛe yi yɛ nnam onwini akwanside wɔ soro ɔhyew insulation layer. Ɛtew ɔhyew a ɛkɔ dade engine dan no mu no so kɛse na esiw dan no ahoɔden a ɛyera esiane ɔhyew a ɛboro so nti no ano.

II. Transpiration Cooling & Gas Film Ɔhyew Insulation a Wɔde Siw Gas Scour tẽẽ

1. Transpiration Cooling Nsunsuanso

Mframa akɛse te sɛ tetrafluoroethylene a ɛnam PTFE porɔwee so ba no fa micro-pores a ɛwɔ insulation layer no ani so kɔ abɔnten te sɛ transpiration wɔ nhyɛso ase. Saa mass ejection adeyɛ yi yi ɔhyew a ɛdɔɔso a ɛwɔ soro no fi hɔ na ɛma onwini a wɔhyɛ ma no ma.

2. Nneɛma a wɔyɛ a ɛfa Gas Film Boundary Layer a ɛwɔ ɔhyew a ɛba fam ho

Mframa a ɛreguan no boaboa ano wɔ ɔfasu no so ma ɛyɛ mframa a ɛsen a ɛtetew mframa a ɛhyew a ɛyɛ hyew kɛse fi ɔfasu no ho. Saa gas film yi wɔ ɔhyew a ɛkorɔn yiye a ɛko tia na ɛma convective heat transfer yɛ mmerɛw kɛse. Nsɔhwɛ ahorow kyerɛ sɛ ebetumi atew ɔhyew a ɛbɛn ɔfasu no so bɛboro 50%.

3. Nneɛma nketenkete a Ɛporɔw no a Wɔbrɛ ase

Gas film no sesa ahoɔhare ne ɔhyew kyekyɛ wɔ ɔhye no mu, na ɛtew nkɛntɛnso tẽẽ ne friction a ɛwɔ two-phase flow a dade nketenkete te sɛ aluminium a ɛwɔ ɔfasu no so no ase kɛse na esiw mfiri a wɔde yi nipadua no ano no ano.

III. Formation of Low-Thermal-Conductivity Char Layer sɛ Honam fam Ɔhyew Akwanside

1. Awo ntoatoaso a ɛyɛ Porous Carbon Skeleton

PTFE pyrolysis akyi no, nkae no yɛ carbonaceous structure a ɛwɔ porous a ɛbata nneɛma a ɛnporɔw ho. Saa char layer yi wɔ 3D network skeleton na ɛkura structural continuity bi mu.

2. Ɔhyew a Ɛba Fam Kɛse

Sɛnea Jiangsu PTFE ntama a ɛyɛ hyew kɛse a wɔyɛ, a wɔde mmeae a ɛda hɔ a wɔato mu ahyɛ mu ma no, char layer no wɔ ɔhyew a ɛba fam koraa sen mfitiase rɔba matrix no, kosi ne kɛse a ɛyɛ 0.1 W/(m·K). Ɛyɛ adwuma sɛ akwanside titiriw a ɛmma ɔhyew nkɔ mu na ɛma ɔhyew a ɛkɔ mu no brɛ ase wɔ ɔfa no mu.

3. Sustained Ɔhyew Insulation & Nhyehyɛe Mmoa

Ɛwom sɛ ɛyɛ porous de, nanso char layer no tumi gyina aerodynamic shear stress bi ano, na ɛma thermal insulation structure no yɛ pɛpɛɛpɛ na ɛbɔ deep-layer nneɛma ho ban fi thermal shock a emu yɛ den ho bere a ɛyɛ adwuma bere tenten no.

IV. Scour Resistance & Ablation Resistance a ɛkɔ anim ma Cladding a wotumi de ho to so

1. Anti-Scour Adwumayɛ denam Low Friction Coefficient so

PTFE ankasa da friction coefficient a ɛba fam koraa adi (~0.04). Sɛ wɔahyɛ no ma wɔ ablation liner no mu a, ɛma frictional shear a gas a ɛsen ntɛmntɛm a ɛyɛ particle-laden de ba no so tew ma ɛyɛ nwonwa, ɛtew mfiri a ɛtwetwe no so, na ɛmma insulation layer no ntumi 'thnned by gas scouring'.

2. Uniform & Stable Ablation Su ahorow

Ne porɔw kɔ so daa na wotumi di so, na ɛda ablation rate a ɛba fam ne char-forming adwumayɛ pa adi. Wɔde insulation layer no di dwuma nkakrankakra na ɛyɛ pɛpɛɛpɛ, na ɛma ɛyɛ kɛse a etu mpɔn bere tenten na wɔkwati sɛ adan mu hyew dodo a entumi nyɛ adwuma yiye a ɛnam mpɔtam hɔ hyew so.

3. Akwankyerɛ Krataa a Wɔtaa De Di Dwuma

Sɛnea Jiangsu PTFE ntama a ɛyɛ hyew kɛse kyerɛ no, wɔ mfiridwuma a mfaso wɔ so mu no, wɔde PTFE powder a ne kɛse te sɛ micron hyɛ matrices a ɛyɛ mmerɛw te sɛ EPDM (Ethylene-Propylene-Diene Monomer) rɔba ne NBR (Nitrile Butadiene Rubber) mu. Wɔnam nkuku a wɔde mia anaasɛ wɔde twitwiw nneɛma so na ɛyɛ ɔhyew dan mu insulation liners ne propellant aburow cladding layers. Wɔde saa nneɛma yi di dwuma kɛse wɔ rɔke mfiri a ɛyɛ den a ɛyɛ aprɛm a efi soro kɔ wim, a ɛko tia po so ahyɛn ne akwan foforo a wɔfa so tow hyɛn ne ahunmu atopae a wɔde tow hyɛn mu de nya ɔhyew ho ahobammɔ a ɛwɔ ɔdan no mu.
