2. V0 "atirimɔdensɛm" sɔhwɛ: vertical combustion sɔhwɛ .
V0 rating a wɔtaa ka ho asɛm no fi sɔhwɛ akwan a wɔagye atom kɛse wɔ UL94 gyinapɛn no mu biako mu: vertical burning test.
Fa no sɛ sɔhwɛ tebea yi:
Vertical Suspension: Standard{0}}Sɔhwɛ Strip (sɛ nhwɛso no, 125mm x 13mm) no gyina hɔ tẽẽ wɔ sɔhwɛ dan a ɛda adi mu. Eyi gyina hɔ ma ɔhyew tebea a ɛyɛ den sen biara, bere a ogyaframa trɛw kɔ soro no.
Fa ogyaframa gu so: Wɔ nhwɛsode no ase no, kyerɛ Bunsen Burner ogyaframa a wɔahyɛ da ayɛ (ɔhyew a ɛboro 500℃) wɔ nhwɛsode no ase ano na hyew kɔ so simma 10.
Yi ogyaframa no na fi ase bere no: sikɔne 10 akyi no, yi ogyaframa no na fi ase gyina dɔn no so na kyerɛw bere a ogyaframa a aka wɔ nhwɛsode no mu no (kyerɛ sɛ, bere a ade no ankasa kɔ so hyew).

Wɔ sɔhwɛ biara akyi no, ɛnsɛ sɛ bere a aka a aka a aka no boro sikani 10.
Ɛnsɛ sɛ ogyaframa a aka nyinaa a aka wɔ sɔhwɛ abien no mu no ntra sikɔne 50.
Sɛ woyi ogyaframa a ɛto so abien no wie a, wontumi nhyew nhwɛsode no koraa.
Ɛnsɛ sɛ nhwɛsode no nya nneɛma a ɛrehyew a ɛreworo so na ɛrehyew dry de-a ɛyɛ frɔmfrɔm cotton a ɛwɔ ase hɔ no. (Eyi ne ade titiriw a ɛbɛma wɔasiw nneɛma afoforo ano!)
Bere a ogyaframa no adum koraa akyi no, spline no ntumi nkɔ so nhyew bɛboro sikɔne 30.
Sɛ yɛde toto ho a, V1 adesuakuw no ma ogyaframa biako a ɛkɔ soro kodu sikani 30 a ne nyinaa yɛ sikani 250 no ho kwan; V2 class no wɔ gyinapɛn a ɛte sɛ V1 nanso ɛma kwan ma nneɛma a ɛhyew no drip kɔ DE-a ɛyɛ frɔmfrɔm cotton so.
Enti, V0 yɛ level a ɛkorɔn sen biara wɔ vertical combustion rating no mu. Ɛgyina hɔ ma su a ɛtra so a ɛne "edum a wodum no ntɛm ara akyi" --ɛnyɛ sɛ wontumi nsɔ, na mmom sɛ ebetumi adum ne ho ntɛmntɛm yiye bere a wɔayi ogya fibea no afi hɔ, na ɛma ɔhyew a ɛwɔ hɔ no so tumi kɛse ne bere a wɔde bedi wo guankɔbea anaa ogya dum bere a ɛsom bo no.
4. Adɛn nti na ɛsɛ sɛ wo dwumadie no di UL94 V0 so?
Sɛ worepaw foamed silicone boards a, UL94 V0 adansedi krataa a wobɛdi akyi no nyɛ sɔhwɛ no a wobɛtwa ara kwa, na mmom egyina hɔ ma awerɛhoɔ a ɛtwa toɔ a ɛfa afiri no ahobanbɔ ne ahotosoɔ ho.
Wɔ battery packs/new energy vehicles: V0-grade silicone foam gaskets betumi asiw ogyaframa a ɛretrɛw no ano yiye bere a ɔhyew a ɛreguan wɔ battery mu, a ɛyɛ "ogya ɔfasu" a ɛbɔ nkwa ne agyapade ahobammɔ ho ban.

5. Sanpu ho bɔhyɛ ahorow .
Wɔ Sanpu Silicone no, yɛte ase yiye sɛ "ahobammɔ nyɛ asɛm a ɛho nhia." Yɛn ogyaframa-retardant foam silicone sheets, sɛ́ ɛyɛ ade a ɛyɛ den anaa nsu a wɔde yɛ no, ɛnyɛ sɛ ɛne UL94 V0 adansedi a emu yɛ den no hyia nko na mmom ɛde ahoɔden a ɛwɔ silicone nneɛma mu no di dwuma nso: ɔhyew a ɛyɛ soronko a ɛko tia (-60℃kosi 200℃+), nsɔano a ɛkorɔn ne cushioning adwumayɛ, ne wim tebea a ɛda nsow ne nnuru a ɛyɛ pintinn.
