Zvakanakira uye Zvakaipa zveInorganic Flame Retardants

Iko kushandiswa kwakapararira kwezvinhu zvepolymer kwakawedzera kukura kweindasitiri inodzoreredza moto. Flame retardants iboka rakakosha zvakanyanya rekuwedzera kwezvinhu munharaunda yanhasi, kudzivirira nekudzivirira moto, kudzora kupararira kwavo, uye kubatsira zvakanyanya mukuchengetedzeka kwekugadzira uye hupenyu hwezuva nezuva. Zvishandiso zvinorapwa nezvinodzoreredza moto zvinokwanisa kudzivirira, kunonoka, kana kumisa kupararira kwemirazvo kana yaiswa kunze kwezvitubu zvemoto, nokudaro zvichiwana mhedzisiro inodzosa moto. Kune marudzi akawanda ezvinodzosa moto, uye chinhu chose chine mativi maviri—zvinodzosa moto zvine zvazvakanakira nezvazvakaipira. Pazasi pane ongororo yezvakanakira uye zvakaipira zvakasiyana-siyana inorganic flame retardants.

Zvakaipa zveInorganic Flame Retardants:
Iyo huru yekudzosera kumashure einorganic flame retardants ndeye yakakwira inodiwa dosage (kazhinji inodarika 50%) muzvinhu zvepolymer, izvo zvinogona kukanganisa zviri nyore kugadzirisa mashandiro uye zvimiro zvemuviri. Mhinduro dzinosanganisira kurapwa kwepamusoro nemaajenti ekubatanidza, ultrafine particle kukwenenzvera, uye nanotechnology, inomiririra gwara rakakosha rekusimudzira mune ramangwana.

Zvakanakira zveInorganic Flame Retardants:

1. Aluminium Hydroxide (ATH): Inosanganisa kunonoka kwemurazvo, kudzvinyirira utsi, uye kuzadza mabasa mune imwe. Haina chepfu, isingaparadzi, yakagadzikana zvakanyanya, haiburitse magasi ane muchetura pakupisa kwakanyanya, inodhura, uye inowanikwa zvakanyanya.
2. Magnesium Hydroxide (MTH): Inoora pakati pe340-490 ° C, ichipa kugadzikana kwekushisa kwakanyanya uye kutaridzika kwemoto kunonoka uye mhedzisiro yehutsi. Iyo inonyanya kukodzera kugadzirisa polyolefin mapurasitiki pakupisa kwepamusoro.
3. Red Phosphorus: Inopa kudzvanywa kweutsi, kuderera kwehupfu, uye kunonoka kwemoto kunoshanda. Nekudaro, tsvuku phosphorus inokonzeresa kune oxidation mumhepo, inogona kungopisa, uye zvishoma nezvishoma inoburitsa muchetura phosphine gasi pamusoro pekuchengetedza kwenguva refu. Kuenderana kwayo nezvinhu zvepolymer kwakashata, ine microencapsulation iriyo yekutanga mhinduro.
4. Ammonium Polyphosphate (APP): Zvakare intumescent flame retardant, ine yakakwira mwero wenitrogen nephosphorus, inoratidza kugadzikana kwakanaka kwekupisa, uye haina kwayakarerekera mukuumbwa. Inogona kusanganiswa nezvimwe zvinodzosa moto, inopa dispersibility yakanaka, uye yakaderera muhupfu, kuve nechokwadi chekushandiswa kwakachengeteka. Nekudaro, kana iyo polymerization degree yeAPP yadzikira, inova yakati wandei-inonyungudika mumvura. Pamusoro pezvo, APP ine acidic zvishoma uye inoda kunyura munyoro munzvimbo dzine hunyoro.
