Qaababka Polypropylene (PP) UL94 V0 iyo V2 ee ka hortaga ololka

Qaababka Polypropylene (PP) UL94 V0 iyo V2 ee ka hortaga ololka

Polypropylene (PP) waa polymer thermoplastic ah oo si weyn loo isticmaalo, laakiin ololkiisu wuxuu xaddidaa isticmaalkiisa meelaha qaarkood. Si loo daboolo shuruudaha kala duwan ee dib-u-celinta ololka (sida darajooyinka UL94 V0 iyo V2), dib-u-celinta ololka waxaa lagu dari karaa si kor loogu qaado iska caabbinta ololka ee PP. Hoos waxaa ku qoran hordhac faahfaahsan oo ku saabsan qaacidooyinka PP ee dab-damiska ee darajooyinka UL94 V0 iyo V2, oo ay ku jiraan xulashada dab-damiska, naqshadeynta qaacidada, farsamooyinka habaynta, iyo tijaabinta waxqabadka.

1. Hordhac ku saabsan Qiimaynta UL94 ee Ka-hortagga Ololka

UL94 waa halbeeg gubasho oo ay sameeyeen Underwriters Laboratories (UL) si loo qiimeeyo iska caabbinta ololka ee agabka balaastikada ah. Qiimaynta caadiga ah ee dib u dhigista ololka waxaa ka mid ah:

• V0: Heerka ugu sarreeya ee dib u dhigista ololka, oo u baahan muunado si ay iskood u damiyaan 10 ilbiriqsi gudahood tijaabada gubashada toosan iyada oo aan la shidin suufka iyadoo dhibicdu da'ayso.
• V2: Heer hoose oo dib u dhac ku yimaada ololka, taasoo u oggolaanaysa muunado inay is-damiyaan 30 ilbiriqsi gudahood tijaabada gubashada toosan iyadoo la oggolaanayo daadashada taasoo keeni karta in suufku shido.

2. Qaacidada PP ee V0 ee ka hortagga ololka

PP-ga ololka ka celiya V0 wuxuu u baahan yahay iska caabin olol oo aad u fiican, oo badanaa lagu gaaro iyadoo lagu daro aaladaha dab-damiska waxtarka sare leh iyo hagaajinta qaacidada.
