Nzira yekugadzira chipanji chelatex chinodzivirira moto?

Panyaya yezvinodiwa zve latex sponge zvinodzivirira moto, zvinotevera ongororo yakavakirwa pane zvimwe zvinhu zviripo zvinodzivirira moto (aluminium hydroxide, zinc borate, aluminium hypophosphite, MCA) pamwe chete nemazano ekugadzira:

I. Kuongororwa kweKushanda kweMoto Unodzivirira Moto Uripo

Aluminium Hydroxide (ATH)
Zvakanakira:

• Inochengetedza nharaunda, inodhura zvishoma.
• Inoshanda kuburikidza nekuora kwe endothermic uye kuburitswa kwemvura, yakakodzera masisitimu asina halogen.

Zvakashata:

• Zvinoda mutoro wakawanda (30-50 phr) kuti zvishande zvakanaka, izvo zvinogona kukanganisa kusimba kwechiponji uye kuwanda kwacho.

Kushanda:

• Yakakodzera mafomura ekutanga anodzivirira moto.
• Zvinokurudzirwa kusanganisa ne synergists (semuenzaniso, zinc borate).

Zinc Borate
Zvakanakira:

• Inodzivirira moto nenzira inoshanda pamwe chete, inowedzera kushanda kweATH.
• Inokurudzira kuumbwa kwechai uye inoderedza utsi.

Zvakashata:

• Kushanda kushoma kana ikashandiswa yoga; inoda kusanganiswa nezvimwe zvinodzora moto.

Kushanda:

• Inokurudzirwa senzira yekubatanidza ATH kana aluminium hypophosphite.

Aruminiyamu Hypophosphite
Zvakanakira:

• Inoshanda zvakanaka, haina halogen, inorema zvishoma (10-20 phr).
• Kugadzikana kwakanaka kwekupisa, kwakakodzera zvinodiwa zvekunonoka kwemoto zvakanyanya.

Zvakashata:

• Mutengo wakakwira.
• Kuenderana kwayo ne latex systems kunoda kuongororwa.

Kushanda:

• Yakakodzera mitemo yekudzora moto zvakanyanya (semuenzaniso, UL94 V-0).
• Inogona kushandiswa yoga kana pamwe chete.

MCA (Melamine Cyanurate)
Zvakanakira:

• Inodzivirira moto ine nitrogen, inodzvinyirira utsi.

Zvakashata:

• Kupararira kusina kunaka.
• Zvinogona kukanganisa kubuda kwefuro.
• Kupisa kwakanyanya kuora (~300°C), hakuenderani nekugadzirwa kwelatex patembiricha yakaderera.

Kushanda:

• Hazvikurudzirwi sechinhu chinokosha; zvinoda kuongororwa kwekuyedza.

II. Mafomu Anokurudzirwa uye Mazano Ekuita

Fomura 1: ATH + Zinc Borate (Sarudzo Yehupfumi)
Kuumbwa:

• Aluminium Hydroxide (ATH): 30-40 phr
• Zinc Borate: 5-10 phr
• Muparadziri (semuenzaniso, musanganiswa we silane): 1-2 phr (inovandudza kupararira)

Hunhu:

• Mari yakaderera, isingakuvadzi nharaunda.
• Yakakodzera zvinodiwa zvekudzivirira moto (semuenzaniso, UL94 HF-1).
• Zvinogona kuderedza zvishoma kusimba kwechipanje; Kugadziriswa kweVulcanization kunodiwa.

Fomura 2: Aluminum Hypophosphite + Zinc Borate (Sarudzo Inoshanda Zvikuru)
Kuumbwa:

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

Hunhu:

• Kushanda nesimba pakunonoka kwemoto, mutoro wakaderera.
• Yakakodzera mamiriro ezvinhu anonyanya kudiwa (semuenzaniso, vertical burn V-0).
• Kuenderana kwealuminium hypophosphite nelatex kunoda kuyedzwa.

Fomura 3: ATH + Aluminium Hypophosphite (Sarudzo Yakaringana)
Kuumbwa:

• Aruminiyamu Hydroxide: 20-30 phr
• Aluminum Hypophosphate: 10-15 phr
• Zinc Borate: 3-5 ph

Hunhu:

• Inoenzanisa mutengo uye mashandiro.
• Inoderedza kuvimba nechinhu chimwe chete chinodzora moto, ichideredza kukanganisa pahunhu hwemoto.

III. Kufunga Nezvemaitiro

Kupararira:

• Zvinhu zvinodzivisa moto zvinofanira kukuyiwa kusvika ≤5μm kudzivirira kukanganisa chimiro chefuro.
• Kuparadzira latex kana michina yekusanganisa inokurumidza kukurudzirwa.

Mamiriro Ekurapa:

• Dzora tembiricha yekupisa (kazhinji 110-130°C ye latex) kudzivirira kuora kwezvinodzivirira moto nguva isati yakwana.

Kuedzwa Kwekushanda:

• Miedzo inokosha: Oxygen Index (LOI), Vertical Burn (UL94), Density, Resilience.
• Kana kunonoka kwemurazvo kusina kukwana, wedzera zvishoma nezvishoma aluminium hypophosphite kana ATH ratios.

IV. Mamwe Mazano

Kuongororwa kweMCA:

• Kana uchiyedza, shandisa 5-10 phr muzvikamu zvidiki kuti uone kuenzana kwefuro.

Zvitupa zvezvakatipoteredza:

• Iva nechokwadi chekuti zvinhu zvinodzora moto zvakasarudzwa zvinoenderana neRoHS/REACH pakutumira zvinhu kunze kwenyika.

Misanganiswa yeSynergistic:

• Funga nezvekuwedzera huwandu hushoma hwe nanoclay (2-3 phr) kuti uwedzere mhedzisiro ye char barrier.
