Polypropylene (PP) UL94 V0 iyo V2 Foomamka Dib u Celinta Ololka

Polypropylene (PP) UL94 V0 iyo V2 Foomamka Dib u Celinta Ololka

Polypropylene (PP) waa polymer thermoplastic oo si weyn loo isticmaalo, laakiin ololkeedu wuxuu xaddidaa codsigiisa meelo gaar ah. Si loo buuxiyo shuruudaha dib u dhigista ololka ee kala duwan (sida UL94 V0 iyo darajooyinka V2), retardants ololka ayaa lagu dari karaa si kor loogu qaado caabbinta ololka ee PP. Hoos waxaa ah horudhac tafatiran oo ku saabsan qaababka PP ololka celinaya ee UL94 V0 iyo V2, oo ay ku jiraan xulashada ololka, naqshadaynta qaabaynta, farsamooyinka habaynta, iyo tijaabinta waxqabadka.

1. Hordhaca Qiimaynta Dib u Dhaca Ololka UL94

UL94 waa jaangooyooyin gubanaya oo ay soo saartay Shaybaarada Underwriters (UL) si loo qiimeeyo caabbinta ololka ee alaabta caagga ah. Qiimaynta caadiga ah ee dib u dhaca ololka waxa ka mid ah:

• V0: Heerka ugu sarreeya ee dib-u-dhaca ololka, oo u baahan muunado si ay isu-demiso 10 ilbiriqsi gudahood tijaabada gubashada tooska ah iyada oo aan la shidin cudbi daadad ah.
• V2: Heerka dib u dhac ololka hoose, oo u oggolaanaya muunado inay is-damiyaan 30 ilbiriqsi gudahood tijaabada gubashada tooska ah iyadoo la oggolaanayo inay shido suufka.

2. V0 Dejinta ololka-dejinta PP

V0 ololka-dejinta PP wuxuu u baahan yahay iska caabin olol oo heer sare ah, sida caadiga ah waxaa lagu gaaraa iyadoo lagu darayo dib-u-celinta ololka waxtarka sare leh iyo hagaajinta qaabeynta.

2.1 Xulashada Dab-demiska

2.4 Imtixaanka Waxqabadka

• UL94 Tijaabada Gubashada ToosanMuunadyadu waa inay buuxiyaan shuruudaha V0 (is-daminta 10 ilbiriqsi gudahood, ma jiro suuf ka shidmaya dhibco).
• Tijaabinta Guryaha Makaanikada: Qiimee xoogga jilicsanaanta, xoogga saameynta, iwm., si loo hubiyo in wax qabadku uu buuxiyo shuruudaha codsiga.

3. V2 Naqshadeynta Olol-Celinta PP

V2 ololka-dejinta PP ayaa leh shuruudaha iska caabbinta ololka oo hooseeya waxaana lagu gaari karaa rarista olol dhexdhexaad ah.

6. Gabagabo

Naqshadeynta qaababka V0 iyo V2 ololka-dejinta PP waxay kuxirantahay shuruudaha iska caabinta ololka ee gaarka ah iyo xaaladaha codsiga.

• V2 qaabayntawaxay gaari kartaa dib u dhac hoose oo ololka ah oo lagu daro waxyaabaha ugu yar (tusaale, dib u dhigista ololka broiled).

Codsiyada wax ku oolka ah, arrimaha sida caabbinta ololka, waxqabadka farsamada, saameynta deegaanka, iyo kharashka waa in la isku dheellitiro si loo hagaajiyo hababka iyo farsamooyinka farsamaynta.
