Dear valued customers and partners: Wɔ yɛn da biara da mfiridwuma ho nkɔmmɔbɔ mu no, yɛahyɛ no nsow sɛ mo mu pii ani gye "temperature ratings" a ɛwɔ silicone foam nneɛma ho no ho kɛse, nanso yɛda so ara wɔ nsɛmmisa. Dɛn ankasa na eyi kyerɛ? Dɛn nti na ɛho hia saa? Wobɛyɛ dɛn atumi apaw abasobɔde a ɛfata ama wo nneɛma? Sɛ́ wo hokafo a wowɔ ne mu ahotoso no, yɛde asi yɛn ani so sɛ yɛbɛboa wo ma woate "temperature code" a ɛwɔ silicone foam nneɛma mu no ase yiye denam akwankyerɛ a emu da hɔ na ɛyɛ mmerɛw yi so.
Dɛn ne ɔhyew a wɔde ma?
Ɛnyɛ akontaahyɛde biako, na mmom "ahobammɔ beae". Sɛ yɛbɛka no tiawa a, ɔhyew a ɛwɔ silicone foam ade mu no kyerɛ ɔhyew a ebetumi ayɛ adwuma pintinn bere tenten na akura ne su atitiriw (te sɛ elasticity, sealing, insulation) mu.
Ma nsusuwii atitiriw abien ntra w’adwenem:
Long-bere a ɛyɛ adwuma no hyew:Ɔhyew a ɛwɔ mu a ade no betumi ayɛ adwuma bere nyinaa nnafua 7 ne nnɔnhwerew 24 a adwumayɛ a ɛbɛsɛe kɛse nni mu. Eyi ne ade titiriw a yegyina so yɛ yɛn nhyehyɛe ne yɛn paw.
Short-bere a ɛyɛ hyew sen biara:Nneɛma no betumi agyina ɔhyew a ano yɛ den ano bere tiaa bi (sɛ nhwɛso no, nnɔnhwerew pii anaa simma du), nanso ɛnsɛ sɛ wɔde di dwuma sɛ ɔhyew a wɔde di dwuma wɔ ɔkwan a ɛfata so. Yɛn adwumakuw no silicone foam ade no, bere tenten a ɛyɛ tenten-bere a wɔde yɛ adwuma no yɛ{7}}60℃kosi +200℃. Eyi kyerɛ sɛ ebetumi adi biribiara ho dwuma fi Arctic no awɔw a ɛyɛ nwononwono so kosi ɔhyew a ɛte sɛ fononoo so.
Dɛn nti na ɔhyew ho akontaabu ho hia kɛse wɔ wo nneɛma no mu?
Ɔhyew a wɔde kyerɛ no nya ahobammɔ so nkɛntɛnso kɛse. Wɔ-temperature applications (te sɛ sealing pads ma ahoɔden kar battery packs foforo ne ɔhyew insulation covers ma mfiridwuma nnwinnade), sɛ ade no nyɛ ɔhyew a ɛko tia, ɛbɛporɔw, powder, anaasɛ mpo hyew, na ɛde sealing huammɔdi, short circuit anaa ogya, ne ahobammɔ ntumi nhyɛ bɔ.
Ɔhyew a wɔde kyerɛ no nya nkɛntɛnso titiriw wɔ sɛnea nneɛma no yɛ adwuma yiye no so: hwɛ hu sɛ nsɔano no da so ara yɛ den wɔ awɔw ne ɔhyew a ɛsesa no mu, hwɛ hu sɛ nnyigyei a ɛbɔ ho ban no so ntew wɔ engine no dan no hyew a ɛkɔ soro no mu, na hwɛ hu sɛ buffer pad no nyɛ den na ɛpaapae wɔ ɔhyew a ɛba fam no mu.
Ɔhyew dodow a wɔde ma no betumi aboa wo ma woatrɛw ade no nkwa nna mu: Sɛ wode di dwuma wɔ ɔhyew a wɔahyɛ no agyirae no mu a, ebetumi atwe ɔhyew a ɛkɔ soro wɔ nneɛma no mu no akyɛ kɛse, na akwati sika a wɔde besi ananmu ntɛm ne ɛka a wɔbɔ wɔ nsiesie ho a efi adwumayɛ a ɛsɛe mu ba no.
