Ammonium polyphosphate inoshanda sei pamwe chete nemelamine uye pentaerythritol mune intumescent coatings?

Mumachira asingapindire moto, kudyidzana pakati peammonium polyphosphate, pentaerythritol, uye melamine kwakakosha pakuwana izvo zvinodiwa zvisingadziviriri moto.

Ammonium polyphosphate (APP) inoshandiswa zvakanyanya senge inodzoreredza murazvo mumashandisirwo akasiyana siyana, kusanganisira machira asingapindire moto.Kana yakafumurwa kune tembiricha yakanyanya, APP inoburitsa phosphoric acid, iyo inopindirana nemahara radicals anogadzirwa panguva yekupisa.Kuita uku kunotungamirira pakuumbwa kwedense uye inodzivirira char layer, iyo inoshanda sechipingamupinyi kudzivirira kupisa uye kutamisa oksijeni, nokudaro kuderedza kupararira kwemoto.

Pentaerythritol musanganiswa wepolol unoshanda sesese kabhoni sosi uye yekuchaya agent.Inoora kana yaiswa pakupisa, ichigadzira zvinhu zvinoputika zvakaita secarbon dioxide nemhute yemvura.Izvi zvinokonzerwa nemagetsi zvinoderedza huwandu hweokisijeni uye hunodzivisa kupisa kwemoto, asi iyo yakasara yekabhoni inoumba char layer yakagadzikana inodzivirira substrate kubva pakuwedzerwa kupisa.

Melamine, musanganiswa wenitrogen-rich, unobatsira pakudzivirirwa nemoto zvemachira.Kana melamine ichipisa, inoburitsa nitrogen gasi, iyo inoita basa rakakosha mukudzvinyirira moto.Iyo nitrogen yakaburitswa inobatsira kudzinga okisijeni, kuderedza oxidizing mhepo yakatenderedza mirazvo, uye nekudaro ichivharira maitiro ekupisa.

Pamwe chete, kupindirana pakati pezvinhu izvi kunobatanidza mhedzisiro yephosphorus, kabhoni, uye nitrogen kuwedzera kupikisa kwemoto kwejasi.Iyo ammonium polyphosphate inoshanda semurazvo unodzoreredza, ichigadzira chinodzivirira char layer.Pentaerythritol inobatsira kucarbonization, ichigadzira char yakawanda kudzivirira kupisa.Chekupedzisira, melamine inoburitsa nitrogen gasi kugadzira mhepo inodzima moto.Nokushanda pamwe chete, zvinhu zvitatu izvi zvinononoka kubatidza uye kunonotsa mwero wekupararira kwemurazvo, zvichiita kuti mabhanhire asingapindi moto ave akachengeteka uye anodzivirira zvakanyanya panjodzi dzemoto.

Shifang Taifeng New Flame Retardant Co., Ltdmugadziri ane makore makumi maviri nemaviri ehunyanzvi mukugadzirwa kweammonium polyphosphate flame retardants, zvigadzirwa zvedu zvinotengeswa kunze kwenyika kune dzimwe nyika.

Yedu inomiririra murazvo retardantTF-201ine eco-inoshamwaridzika uye ine hupfumi, ine mature application mune intumescent coatings, textile back coating, mapurasitiki, huni, tambo, anonamira uye PU furo.

Kana uchida kuziva mamwe mashoko, tapota taura nesu.
