Izisombululo ezithintela ilangatye ze-thermoplastic elastomer TPE

Xa usebenzisa i-aluminium hypophosphite (AHP) kunye ne-melamine cyanurate (MCA) kwi-thermoplastic elastomers (TPE) ukuze ufumane i-UL94 V0 flame-retardant rating, kubalulekile ukuqwalasela indlela yokuthintela umlilo, ukuhambelana kwezinto, kunye neemeko zokucubungula. Apha ngezantsi kukho indlela ecetyiswayo:

1. Ukulayisha Okuqhelekileyo Xa Kusetyenziswa Ngamnye

I-Aluminium Hypophosphite (AHP)

• Ukulayisha: 15-25%
• Iimpawu: Ikhuthaza ukwakheka kwe-char, ifanelekile kwiinkqubo ezifuna ukusebenza okuphezulu koomatshini, kodwa ubushushu bokucubungula kufuneka bulawulwe (kucetyiswa ukuba ≤240°C).

I-Melamine Cyanurate (MCA)

• Ukulayisha: 25-35%
• Iimpawu: Ixhomekeke ekuqhekekeni kwe-endothermic kunye nokuxutywa kwegesi; umthwalo ophezulu unokunciphisa ukuguquguquka kwezinto.

2. Ifomula yokuxuba ecetyiswayo

Umlinganiselo wokudibanisa we-AHP kunye ne-MCA

• I-AHP: 10-15%
• I-MCA: 10-20%
• Ukulayisha okupheleleyo: 20-30%

Iingenelo: Isiphumo sokusebenzisana sinciphisa umthwalo opheleleyo ngelixa sinciphisa impembelelo kwiimpawu zoomatshini (umz., amandla okutsalwa, ukuthamba).

3. Izinto Eziphambili Ezinefuthe

• Uhlobo lwezinto ezisisiseko: Ii-TPE ezisekelwe kwi-SEBS zihlala zilula ukuzibamba umlilo kunezo zisekelwe kwi-SBS, nto leyo evumela ukuba umthwalo wokongeza ube mncinci kancinci.
• Ubukhulu beSampuli: Ukuhambelana kwe-UL94 V0 kuthintela ubukhulu (i-1.6mm inzima kune-3.2mm), ngoko ke iifomyula kufuneka zilungiswe ngokufanelekileyo.
• Abantu abasebenzisanayoUkongeza i-2-5% ye-nano-clay okanye i-talc kunokuphucula ukwakheka kwe-char kwaye kunciphise umthwalo othintela ilangatye.
• Ubushushu bokucubungula: Qinisekisa ukuba amaqondo obushushu okucubungula ahlala engaphantsi kwamanqaku okubola e-AHP (≤240°C) kunye ne-MCA (≤300°C).

4. Amanyathelo okuqinisekisa acetyiswayo

• Uvavanyo lwangaphambili: Yenza uvavanyo oluncinci nge-AHP 12% + MCA 15% (iyonke yi-27%).
• Uvavanyo Lokusebenza: Vavanya ukuthintela ilangatye (ukutsha ngokuthe nkqo kwe-UL94), ubulukhuni (uMfula A), amandla okutsalwa, kunye nesalathisi sokuhamba kokunyibilika.
• Ukwenziwa ngconoUkuba kukho ukuvuza, yongeza umlinganiselo we-AHP (ukwandisa ukutsha); ukuba iimpawu zoomatshini azintle, cinga ngokongeza iiplastiki okanye ukunciphisa umthwalo uwonke.

5. Amanyathelo okuzikhusela

• Kuphephe ukudibanisa nezinto zokuzalisa ezine-asidi (umz., izinto ezithile ezifaka imibala), kuba zinokuphazamisa i-AHP.
• Ukuba i-TPE inezixa ezikhulu zeeplastiki ezisekelwe kwioyile, umthwalo othintela ilangatye unokufuneka wonyuswe (ioyile inokunciphisa ukusebenza kakuhle kokuthintela ilangatye).

Ngokuxutywa okunengqiqo kunye nokwenza ngcono uvavanyo, ukuthobela i-UL94 V0 kunokufezekiswa ngelixa kulungelelaniswa ukucutshungulwa kwe-TPE kunye nokusebenza koomatshini. Kucetyiswa ukusebenzisana nababoneleli abathintela ilangatye kwizisombululo ezenzelwe wena.
