Nzira yekuita sei flame retardant latex sponge?

Nekuda kwezvinoda kudzoreredza moto zve latex sponge, inotevera ongororo yakavakirwa pane akati wandei aripo anodzoreredza moto (aluminium hydroxide, zinc borate, aluminium hypophosphite, MCA) pamwe nekurudziro yekugadzira:

I. Ongororo Yezviripo Flame Retardant Applicability

Aluminium Hydroxide (ATH)
Zvakanakira:

• Kuchengetedza zvakatipoteredza, mutengo wakaderera.
• Inoshanda kuburikidza ne endothermic decomposition uye mvura vapor kusunungurwa, yakakodzera halogen-isina masisitimu.

Zvakaipa:

• Inoda kurodha yakakwira (30-50 phr) yekubudirira, iyo inogona kukanganisa siponji elasticity uye density.

Kushanda

• Inokodzera kugadzirwa kwebasic flame retardant.
• Inokurudzirwa kusanganisa ne synergists (semuenzaniso, zinc borate).

Zinc Borate
Zvakanakira:

• Synergistic flame retardant, inowedzera kushanda kweATH.
• Inosimudzira kuumbwa kwechar uye inodzvinyirira utsi.

Zvakaipa:

• Kushanda zvishoma kana kushandiswa chete; inoda kusanganiswa nemamwe maretardants emoto.

Kushanda

• Yakakurudzirwa se synergist yeATH kana aluminium hypophosphite.

Aluminium Hypophosphite
Zvakanakira:

• Yakanyanya kushanda, halogen-isina, yakaderera kurodha (10-20 phr).
• Kugadzikana kwakanaka kwekupisa, kwakakodzera kune yakakwira murazvo retardancy zvinodiwa.

Zvakaipa:

• Mutengo wepamusoro.
• Kuenderana ne latex system inoda kuongororwa.

Kushanda

• Inokodzera yakakwirira murazvo retadancy zviyero (semuenzaniso, UL94 V-0).
• Inogona kushandiswa chete kana kusanganiswa.

MCA (Melamine Cyanurate)
Zvakanakira:

• Nitrogen-based flame retardant, inosvuta utsi.

Zvakaipa:

• Murombo dispersibility.
• Inogona kukanganisa kubuda furo.
• High decomposition tembiricha (~ 300°C), isingaenderani nekudzika-tembiricha latex processing.

Kushanda

• Hazvikurudzirwi sechinhu chekutanga; inoda kusimbiswa kwekuedza.

II. Magadzirirwo Akakurudzirwa uye Mazano eMaitirwo

Kugadzira 1: ATH + Zinc Borate (Economical Option)
Kuumbwa:

• Aluminium Hydroxide (ATH): 30-40 phr
• Zinc Borate: 5-10 phr
• Dispersant (semuenzaniso, silane coupling agent): 1-2 phr (inovandudza dispersibility)

Hunhu:

• Mutengo wakaderera, ushamwari kwezvakatipoteredza.
• Inokodzera zvakajairwa murazvo retadancy zvinodiwa (semuenzaniso, UL94 HF-1).
• Inogona kuderedza zvishoma kusimba kweponji; Vulcanization optimization inodiwa.

Kugadzira 2: Aluminium Hypophosphite + Zinc Borate (Yakakwirira-Kushanda Sarudzo)
Kuumbwa:

• Aluminium Hypophosphite: 15-20 phr
• Zinc Borate: 5-8 phr
• Plasticizer (semuenzaniso, parafini yemvura): 2-3 phr (inovandudza mashandiro)

Hunhu:

• High flame retardancy performance, yakaderera kurodha.
• Inokodzera mamiriro ekudiwa kwepamusoro (semuenzaniso, vertical burn V-0).
• Kuenderana kwealuminium hypophosphite ine latex inoda kuongororwa.

Kugadzira 3: ATH + Aluminium Hypophosphite (Yakaenzana Sarudzo)
Kuumbwa:

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

Hunhu:

• Balances mutengo uye maitiro.
• Inoderedza kuvimba pane imwe chete inodzoreredza murazvo, ichideredza kukanganiswa kwezvinhu zvemuviri.

III. Maitiro Kufunga

Dispersibility:

• Zvidzoreso zvemoto zvinofanirwa kudzikiswa kusvika ≤5μm kudzivirira kukanganisa chimiro chefuro.
• Pre-dispersion mu latex kana high-speed mixing equipment inokurudzirwa.

Curing Conditions:

• Kudzora tembiricha yekurapa (kazhinji 110-130 ° C ye latex) kudzivirira kupera nguva isati yakwana kwezvinodzosa moto.

Performance Testing:

• Miedzo yakakosha: Oxygen Index (LOI), Vertical Burn (UL94), Density, Resilience.
• Kana murazvo wemoto usina kukwana, zvishoma nezvishoma wedzera aluminium hypophosphite kana ATH ratios.

IV. Zvimwe Zvinokurudzira

Kuedzwa kwe MCA:

• Kana muyedzo, shandisa 5-10 phr mumabheji madiki kuona maitiro ekupupa kufanana.

Environmental Certification:

• Ita shuwa kuti zvinodzosa moto zvakasarudzwa zvinoenderana neRoHS/REACH yekutumira kunze.

Synergistic Blends:

• Funga kuwedzera mashoma e nanoclay (2-3 phr) kuwedzera char barriers mhedzisiro.
