I-Aluminium Hypophosphite ethintela ilangatye kunye ne-MCA ye-EVA Heat-Shrink Tubing

I-Aluminium Hypophosphite ethintela ilangatye kunye ne-MCA ye-EVA Heat-Shrink Tubing

Xa usebenzisa i-aluminium hypophosphite, i-MCA (melamine cyanurate), kunye ne-magnesium hydroxide njengezithinteli zomlilo kwi-EVA heat-shrink tube, uluhlu olucetyiswayo lwedosi kunye nemiyalelo yokwenza ngcono zezi zilandelayo:

1. Imilinganiselo ecetyiswayo yeZithinteli zomlilo

I-Aluminium Hypophosphite

Idosi:5%–10%
Umsebenzi:Isebenza kakuhle kakhulu ekuthinteleni ilangatye, ikhuthaza ukwakheka kwetsha, kwaye inciphisa izinga lokukhululwa kobushushu.
Phawula:Ubuninzi obugqithisileyo bunokuphazamisa ukuguquguquka kwezinto; kufuneka kufakwe izinto ezisebenzisanayo ukuze kuphuculwe umgangatho.

I-MCA (iMelamine Cyanurate)

Idosi:10%–15%
Umsebenzi:I-gas-phase flame retardant, ifunxa ubushushu kwaye ikhuphe iigesi ezingasebenziyo (umz., i-NH₃), isebenzisana ne-aluminium hypophosphite ukuphucula i-flame retardant.
Phawula:Ukulayisha kakhulu kunokubangela ukufuduka; kufuneka kuqinisekiswe ukuba kuyahambelana ne-EVA.

I-Magnesium Hydroxide (Mg(OH)₂)

Idosi:20%–30%
Umsebenzi:Ukubola kwe-endothermic kukhupha umphunga wamanzi, kunyibilikise iigesi ezivuthayo kwaye kuthintele umsi.
Phawula:Umthwalo ophezulu unokunciphisa iipropati zoomatshini; kucetyiswa ukuba kutshintshwe umphezulu ukuze kuphuculwe ukusasazeka.

2. Iingcebiso zokuphucula ukwenziwa kwefomyula

Inkqubo Ethintela Ilangatye Iyonke:Akufuneki kudlule i-50% ukulinganisela ukungabikho kokukhanya kwelangatye kunye nokukwazi ukulisebenzisa (umz., ukuguquguquka, izinga lokuncipha).
Iziphumo zokusebenzisana:
I-aluminium hypophosphite kunye ne-MCA zinokunciphisa iidosi nganye nganye (umz., i-8% ye-aluminium hypophosphite + 12% ye-MCA).
I-Magnesium hydroxide incedisana nokungavuthi komlilo ngokusebenzisa iziphumo ze-endothermic ngelixa inciphisa umsi.
Unyango Lomphezulu:Iiarhente zokudibanisa i-silane zinokuphucula ukusasazeka kunye nokubopha kwe-interfacial ye-magnesium hydroxide.
Izongezo eziNcedisayo:
Yongeza ii-2%–5% zezinto ezenza i-char-forming agents (umz., i-pentaerythritol) ukuphucula uzinzo lwe-char layer.
Faka izixa ezincinci zeeplastiki (umz., ioyile yesoya efakwe i-epoxidized) ukuze kulungiswe ukulahleka kokuguquguquka.

3. Imiyalelo yoQinisekiso lokuSebenza

Uvavanyo lokuBuyiselwa yiLanga:
Uvavanyo lokutshisa oluthe nkqo lwe-UL94 (ithagethi: V-0).
Umlinganiselo we-Oxygen Index (LOI >28%).
Iipropati zoomatshini:
Hlola amandla okuxinana kunye nobude ngexesha lokuphumla ukuqinisekisa ukuba ukuguquguquka kuyahlangabezana neemfuno zesicelo.
Ukuqhubekeka:
Jonga iMelt Flow Index (MFI) ukuze uphephe ubunzima bokucubungula ngenxa yokugcwala kakhulu kwezinto ezizalisa amanzi.

4. Iingqwalasela zeendleko kunye nokusingqongileyo

Ibhalansi yeendleko:I-aluminium hypophosphite ibiza kakhulu; idosi yayo ingancitshiswa (yongezwe nge-MCA) ukulawula iindleko.
Ubuhlobo nokusingqongileyo:I-Magnesium hydroxide ayinabungozi kwaye ithintela umsi, nto leyo eyenza ukuba ifaneleke ukusetyenziswa ngendlela enobuhlobo nokusingqongileyo.

Umzekelo Wokwenziwa (ngokwereferensi kuphela):
