Sanpu Silicone Co., Ltd.-a operations specialist ka nih angin, product flame retardant ratings chungchangah client-te hnen atangin zawhna ka dawng fo thin. Standard sawi tam ber leh khauh taka mamawh chu ‘UL94 V0’ a ni. Mi tam takin he designation hi ‘flame retardant’ anga an hriat laiin, a awmzia dik tak leh hlutna chu heng character pahnih aia hla takah a inzar pharh a ni.
Vawiin hian "UL94 V0" tih awmzia chu ngun takin kan sawifiah ang a, chu chu kan test report leh product specification-ah a lang fo thin.
1. UL94 chu eng nge ni? "Flame-retardant" tih label bulpui mai a ni lo.
A hmasa berin, eng nge' ul 'stands for. UL hi United Laboratory tih tawi a ni a, khawvel puma hriat hlawh leh rintlak tak safety certification body a ni. Material safety lama international examiner’ angin i ngaihtuah thei ang.
UL94 hi UL standard a ni a, a bik takin plastic materials meialh performance test nan a bik takin siam a ni a, elastomers te pawh kan foamed silicone ang chi te pawh a tel. Chuvangin, material pakhatin UL94 certification a pass nia a sawi chuan, testing process khauh tak leh scientific hmanga finfiah a nih tawh tihna a ni.
2. V0 hian "cruel" a nei a, chungte chu vertical combustion test a ni.
V0 rating tia sawi tlangpui hi UL94 standard-a testing method hman lar ber pakhat a\\anga lo chhuak a ni a, chu chu vertical burning test a ni.
He test scenario hi han ngaihtuah teh:
Vertical Suspension: Standard-Test strip lian tak (eg, 125mm x 13mm) chu test chamber langtlang takah vertical-in an dah a. Hei hian meialh a\\anga a darh zau zel angin, meikhu chhuahna tur (combustion scenario) mamawh ber a entir a ni.
Meialh: Sample strip hnuaiah chuan sample strip hnuai lam kil khatah standardized bunsen burner flame (temperature 500℃aia sang ) chu direct la, second 10 chhung burn chhunzawm zel rawh.
Meialh chu la chhuakin timer chu tan la: 10 seconds hnuah, meialh chu la chhuakin stopwatch chu start la, sample-a meialh la awm (chu chu, material ngei pawh a kang chhunzawm zel hun tur) record turin.
Secondary Ignition: Sample strip-a meialh a lo chhuah zawh hnuah, second 10 chhung meialh hnawih leh nghal tur a ni.
Record leh rawh: meialh chu la chhuakin meialh kang la awm leh a kang la (meialh a kang lo) hun chhung chu record rawh.
Test chuan material chu accidental accidental contact hnuah a self-extinguish dawn em tih chu simulated a ni a, chu chuan kangmei darh tur a veng thei a ni.
3. V0-a "graduation criteria": data chu sawi rawh
"Double Burning" process rapthlak tak hnuah chuan material pakhat chuan V0 certification neih theihna turin criteria khauh tak pathumte a tlin vek a ngai a ni.
Test eng pawh tih zawhah chuan residual flame hal hun pakhat chauh chu second 10 aia tam lo tur a ni.
Test pahnih chhunga meialh hal hun chhung zawng zawng chu second 50 aia rei lo a ni tur a ni.
Meialh pahnihna lak chhuah hnuah chuan sample chu a kang vek thei lo.
Sample-ah chuan a hnuaia cotton lian tak, dry de-greased chu burning material dripping leh igniting a awm tur a ni lo. (Hei hi thil dang ignition venna kawng pawimawh tak a ni!)
Meialh a kang vek hnuah chuan spline chu second 30 aia rei a kang chhunzawm thei lo.
Inthlauhna atan V1 class hian flame duration vawi khat chhung second 30 thleng a phalsak a, a vaiin second 250 thleng a phalsak a; V2 class hian V1 nen standard inang mahse burning material chu de-greased cotton-ah a tlak theih phah a ni.
Chuvangin, vertical combustion rating-ah chuan V0 hi level sang ber a ni. "Extinguishing immediately after removal" -- a eng thei lo tihna ni lovin, kangmei chhuahna hmun lakchhuah a nih hnuah a inhnuhdawh nghal vat thei tihna a ni lo va, kangmei chhuah hun leh kangmei chhuahna hun hlu tak hneh theihna hun a hmang tam thei hle.
4. Engvangin nge i project hian UL94 V0 hi a zawm tur?
Foamed silicone board thlan hunah UL94 V0 certification zawm hi test pass mai mai a ni lo va, product himna leh rintlakna guarantee hnuhnung ber a ni.
Battery pack/new energy tan lirthei: V0-grade silicone foam gaskets hian battery thermal runaway laiin meialh darh zel tur a veng thei a, hei hi nunna leh thil neih himna humhim nan "firewall" a ni.
Electronic hmanrua leh charging station tan: hmun inkharkhip chhunga short circuit te hian hlauhawmna a thlen tlangpui. V0 Materials In chhunga meialh te te chu a pumin a pung thei lo-scale fires.
Construction/transportation atan: lawngah chuan high{0}}speed rail leh public facilities-ah chuan flame retardant property of materials hi ram pum huap standard a ni a, nunna himna atana thil harsa tak a ni.
5. Sanpu-a thutiamte .
Sanpu Silicone-ah chuan "Safety hi thil tenawm a ni lo" tih hi kan hrethiam tak zet a ni. Kan meialh-retardant foam silicone sheets, solid emaw liquid emaw formulations te hian UL94 V0 certification khauh tak an tlin mai bakah silicone materials-a inherent strengths te chu an hmang tangkai bawk a: exceptional temperature resistance (-60℃to 200℃+), sealing leh cushioning performance sang zawk leh weather resistance ropui tak leh chemical stability te an hmang thei a ni.
UL94 V0 certification dik tak nei material thlan hi cost-nakin lawka risk-a investment a ni lo.
He science article hian he key metric hi a hriatthiam theih nan a puih ngei kan beisei. Selection process-a project bik i neih chuan engtik lai pawhin kan technical team te hnenah zawhfiah theih a ni. Professional solutions kan pe ang che.
