Silicone foam boards betumi anya ɔhyew a ɛyɛ pɛ a ɛnyɛ ade biako so, na mmom esiane nkɛntɛnso a wɔaka abom a wɔn honam fam su, microstructure ne macroscopic nhyehyɛe ka ho nti. Yebetumi ate ase sɛ "ɔhyew kyekyɛ ne transfer nhyehyɛe" a etu mpɔn.
Nea edidi so yi yɛ akwan titiriw anan a ɛnam so nya ɔhyew a ɛyɛ pɛ:
1. Nneɛma fapem: ɔhyew a ɛwɔ mu a ɛwɔ silicone rɔba ankasa mu no ankasa .

Ɔhyew a ɛyɛ den: .
Silicone betumi akura adwumayɛ a ɛyɛ den mu wɔ ɔhyew a ɛtrɛw a ɛyɛ -60℃kosi 200℃, a ɛkyerɛ sɛ ɔhyew no kwan no rentumi nni nkogu esiane ɔhyew a ɛsakra nti.
2. Core Mystery: Nkwammoaa nhyehyɛe a wotumi di so - a ɛyɛ "ɔhyew a ɛsen fa ntam".
Eyi ne nsonsonoe titiriw a ɛsen biara wɔ ɔhyew a ɛkɔ mu no mu wɔ foam boards ne solid boards ntam.
Nkyɛmu a ɛyɛ pɛ:
High{}}Quality silicone foam boards no wɔ fine, uniform ne closed-nkwaboaa nkwammoaa nhyehyɛe. Saa ntini yi nyɛ nea ɛyɛ mmerɛw nanso wɔkyekyɛ no pɛpɛɛpɛ wɔ nneɛma no mu nyinaa te sɛ ɛwo a wɔde yɛ adwuma.
Sɛ wode abiɛsa-dimensional thermal conductive network si hɔ:
Fa no sɛ ɔhyew a efi silicone pad a ɛyɛ den a ɛma ɔhyew ba mu no yɛ ɔkwan a ɛyɛ den so. Wɔ foam boards mu no, nkwammoaa no afasu no bɛyɛ akwan foforo a ɛma ɔhyew kɔ so. Wobetumi de ɔhyew akɔ bere koro mu afa saa tokuru afasu a ɛka bom yi ho wɔ ade no tenten, ne tɛtrɛtɛ ne ne kɛse mu, na ɛyɛ ɔhyew kyekyɛ nhyehyɛe a ɛwɔ afã-afã ne nea ɛwɔ ntam no. Eyi te sɛ nea wɔreyɛ biako-log bridges a ɛtoatoa so no foforo akɔ crisscrossing network a ɛwɔ bridges a ɛkorɔn mu, a ɛma ɔhyew no trɛw ntɛmntɛm na ɛyɛ pɛpɛɛpɛ.

Eyi yɛ anammɔn titiriw a ɛbɛma ɔhyew atumi akɔ foam board no mu yiye afi ɔhyew fibea no mu.
Nneɛma a wɔde hyɛ mu ma:
Ɛte sɛ nea ɔfasu a ɛyɛ mmerɛw sen biara mpo nyɛ pɛpɛɛpɛ wɔ afiri ketewaa bi mu. Sɛ ade no yɛ den a, mframa mu nsonsonoe kɛse bɛba ne ne ɔhyew fibea no ne ɔhyew a ɛresɛe no ntam. Mframa yɛ ɔhyew kwan a enye, a ɛbɛyɛ "ahoɔden a wɔde ko tia" kɛse.
Tew contact thermal resistance so:
Silicone foam boards no yɛ mmerɛw koraa na ebetumi akɔ nhyɛso mu deformation a ɛho hia mu wɔ nhyɛso ketewaa bi ase. Ebetumi ahyɛ saa micro-a ɛnyɛ pɛ ne macro-aboaboa ano a ɛyɛ pɛpɛɛpɛ te sɛ nsa a ɛyɛ mmerɛw, a ɛrepiapia mframa a akyere no. Saa kwan yi so no, ɔhyew betumi akɔ "ɔhyew conduction network" a ɛwɔ foam board no mu a akwanside biara mfi ɔhyew fibea no ani, na afei wɔde akɔ soro a ɛyɛ hyew no nyinaa afi ntam.
4. Nkɛntɛnso a ɛba wɔ ne nyinaa mu: Ɔhyew a "ɛyɛ pɛ" .
Sɛ yɛka atifi hɔ nsɛm abiɛsa no bom a, silicone foam board no te sɛ "ɔhyew buffer pool" anaa "equalizer" :
1.Absorption a ɛyɛ adwuma yiye: .
Ɔhyew no yɛ ntɛmntɛm "absorbed" kɔ foam board no mu fi hot spot (te sɛ resistance wire) denam interface no so ne low contact thermal resistance.
2.Abiɛsa-Afã a ɛtrɛw:
Sɛ ɔhyew hyɛn mu wie a, ɛtrɛw ntɛmntɛm wɔ akwan nyinaa so fa abiɛsa-dimensional cell network a ɛwɔ mu no mu.
3.Uniform a wɔayi no adi:
Awiei koraa no, ɔhyew no dannan fi "point" anaa "line" ɔhyew fibea ma ɛyɛ ɔhyew fibea a ɛyɛ pɛ "fam" na ɛma ɛyɛ mmerɛw.
