Ungayenza njani i-latex sponge ethintela ilangatye?

Kwiimfuno zesiponji selatex ezithintela ilangatye, olu hlalutyo lusekelwe kwizinto ezininzi ezithintela ilangatye ezikhoyo (i-aluminium hydroxide, i-zinc borate, i-aluminium hypophosphite, i-MCA) kunye neengcebiso zokwenziwa:

I. Uhlalutyo Lokusetyenziswa Komlilo Okhoyo Okuthintela Ilangatye

I-Aluminium Hydroxide (ATH)
Iingenelo:

• Inobuhlobo nokusingqongileyo, ixabiso liphantsi.
• Isebenza ngokubola kwe-endothermic kunye nokukhululwa komphunga wamanzi, ifanelekile kwiinkqubo ezingenayo i-halogen.

Iingxaki:

• Ifuna umthwalo ophezulu (30-50 phr) ukuze isebenze kakuhle, nto leyo enokuchaphazela ukuthamba kwesiponji kunye noxinano.

Ukusebenza:

• Ifanelekile kwiifomyula ezisisiseko ezithintela ilangatye.
• Kucetyiswa ukuba idityaniswe ne-synergists (umz., i-zinc borate).

I-Zinc Borate
Iingenelo:

• I-synergistic flame retardant, iphucula ukusebenza kakuhle kwe-ATH.
• Ikhuthaza ukwakheka kwe-char kwaye ithintela umsi.

Iingxaki:

• Ukusebenza kakuhle xa isetyenziswa yodwa; ifuna ukuhlanganiswa nezinye izinto ezithintela umlilo.

Ukusebenza:

• Icetyiswa njenge-synergist ye-ATH okanye i-aluminium hypophosphite.

I-Aluminium Hypophosphite
Iingenelo:

• Isebenza kakuhle kakhulu, ayinayo i-halogen, ilayisha kancinci (10-20 phr).
• Uzinzo oluhle lobushushu, olufanele iimfuno zokudanyaza komlilo okuphezulu.

Iingxaki:

• Ixabiso eliphezulu.
• Ukuhambelana neenkqubo zelatex kufuna ukuqinisekiswa.

Ukusebenza:

• Ifanelekile kwimigangatho ephezulu yokungatshisi ilangabi (umz., UL94 V-0).
• Ingasetyenziswa yodwa okanye idibene.

I-MCA (iMelamine Cyanurate)
Iingenelo:

• I-nitrogen-based flame retarder, ethintela umsi.

Iingxaki:

• Ukusasazeka kakubi.
• Ingaphazamisana nokuphuma kwegwebu.
• Ubushushu obuphezulu bokubola (~300°C), abufani nokulungiswa kwe-latex kubushushu obuphantsi.

Ukusebenza:

• Ayikhuthazwa njengento ephambili; ifuna ukuqinisekiswa kovavanyo.

II. Iifomyula ezicetyiswayo kunye neengcebiso zeNkqubo

Ifomula 1: I-ATH + I-Zinc Borate (Ukhetho Lwezoqoqosho)
Ulwakhiwo:

• I-Aluminium Hydroxide (ATH): 30-40 phr
• I-Zinc Borate: 5-10 phr
• Isisasazi (umz., iarhente yokudibanisa i-silane): 1-2 phr (iphucula ukusasazeka)

Iimpawu:

• Ixabiso liphantsi, ayingcolisi okusingqongileyo.
• Ifanelekile kwiimfuno zokungatshisi ilangabi ngokubanzi (umz., UL94 HF-1).
• Inganciphisa kancinci ukuqina kwesiponji; Kufuneka ukulungiswa kweVulcanization.

Ifomula yesi-2: I-Aluminium Hypophosphite + i-Zinc Borate (Ukhetho oluSebenza kakuhle)
Ulwakhiwo:

• I-Aluminium Hypophosphite: 15-20 phr
• I-Zinc Borate: 5-8 phr
• I-plasticizer (umz., iparafini engamanzi): 2-3 phr (iphucula ukusebenziseka kwayo)

Iimpawu:

• Ukusebenza kakuhle kokulibaziseka komlilo, ukulayisha okuphantsi.
• Ifanelekile kwiimeko ezifunwa kakhulu (umz., ukutsha ngokuthe nkqo V-0).
• Ukuhambelana kwe-aluminium hypophosphite ne-latex kufuna uvavanyo.

Ifomula 3: I-ATH + i-Aluminium Hypophosphite (Ukhetho oluLungelelanisiweyo)
Ulwakhiwo:

• I-Aluminium Hydroxide: 20-30 phr
• I-Aluminium Hypophosphite: 10-15 phr
• I-Zinc Borate: 3-5 phr

Iimpawu:

• Ibhalansi yeendleko kunye nokusebenza.
• Inciphisa ukuxhomekeka kwisixhobo esinye esithintela ilangatye, inciphisa impembelelo kwiimpawu zomzimba.

III. Izinto eziqwalaselwayo kwinkqubo

Ukusasazeka:

• Izinto ezithintela ilangatye mazigaywe zibe yi-≤5μm ukuze zingaphazamisi ulwakhiwo lwefoam.
• Kucetyiswa ukuba kusetyenziswe izixhobo zokuxuba i-latex okanye ezisebenzisa isantya esiphezulu ngaphambi kokuba zisasazwe.

Iimeko Zokuphilisa:

• Lawula ubushushu bokunyanga (ngesiqhelo yi-110-130°C kwi-latex) ukuthintela ukubola kwangaphambi kwexesha kwezinto ezithintela ilangatye.

Uvavanyo Lokusebenza:

• Uvavanyo olubalulekileyo: I-Oxygen Index (LOI), i-Vertical Burn (UL94), i-Density, i-Resilience.
• Ukuba ukuthintela ilangatye akwanelanga, yongeza kancinci kancinci i-aluminium hypophosphite okanye i-ATH ratios.

IV. Iingcebiso ezongezelelweyo

Uvavanyo lwe-MCA:

• Ukuba uvavanya, sebenzisa i-5-10 phr kwiibhetshi ezincinci ukuze ubone impembelelo ekulinganeni kwe-foam.

Iziqinisekiso zeNdalo:

• Qinisekisa ukuba izinto ezithintela ilangatye ezikhethiweyo ziyahambelana neRoHS/REACH xa kuthunyelwa kwamanye amazwe.

Iindidi eziHlanganisiweyo:

• Cinga ngokongeza amanani amancinci e-nanoclay (2-3 phr) ukuze uphucule imiphumo yokuthintela i-char.
