Mafuta anodzoreredza akakosha ekuwedzera anoshandiswa mumhando dzakasiyana siyana, kunyanya mapurasitiki, kuderedza kupisa uye kuwedzera kuchengetedzwa kwemoto. Sezvo kudiwa kwezvigadzirwa zvakachengeteka kunowedzera, kusimudzira uye kushandiswa kwemoto retardants zvakashanduka zvakanyanya. Ichi chinyorwa chinoongorora marudzi akasiyana-siyana emoto anodzoreredza anowanzo shandiswa mumapurasitiki, maitiro avo ekuita, uye zvazvinoreva zvakatipoteredza.
Halogenated flame retardants ndeimwe yeanonyanya kushandiswa muindasitiri yemapurasitiki. Mishonga iyi ine bromine kana chlorine uye inoshanda mukuvhiringa nzira yekupisa. Kana vasangana nekupisa, vanoburitsa maatomu ehalogen anoita nemahara radicals mumurazvo, zvichinyatso kudzima moto. Mienzaniso yakajairika inosanganisira tetrabromobisphenol A (TBBPA) uye polybrominated diphenyl ethers (PBDEs). Kunyange zvichishanda, kushushikana pamusoro pekushingirira kwavo kwezvakatipoteredza uye njodzi dzinogona kuitika dzehutano zvakakonzera kuwedzera kuongororwa uye mutemo.
Phosphorus-based flame retardants iri kuwana mukurumbira nekuda kwekushanda kwavo uye kuderera kwemamiriro ekunze zvichienzaniswa nesarudzo dzehalogenated. Mishonga iyi inogona kuiswa mumhando mbiri huru: reactive uye additive. Reactive phosphorus flame retardants kemikari inobatana nepolymer panguva yekugadzira, nepo mhando dzekuwedzera dzichiramba dzakasanganiswa mukati mepurasitiki. Mienzaniso inosanganisira triphenyl phosphate (TPP) uye ammonium polyphosphate (APP). Vanoshanda nekusimudzira kuumbwa kwechar, iyo inoshanda sechipingamupinyi pakupisa uye oxygen, nekudaro ichidzikamisa kupisa.
Inorganic flame retardants, senge aluminum hydroxide uye magnesium hydroxide, isiri-chepfu uye ine hushamwari dzimwe nzira. Mishonga iyi inoburitsa mhute yemvura kana yapiswa, inotonhodza zvinhu uye inoderedza magasi anobvira. Zvinowanzo shandiswa mumashandisirwo apo kuchengetedzwa kwakakosha, senge mumagetsi nemagetsi zvishandiso. Kunyange zvazvo zvisinganyanyi kushanda pakudzika kwakadzika kana zvichienzaniswa nehalogenated kana phosphorus-based retardants, mararamiro avo ekuchengetedza anovaita sarudzo inosarudzwa mumashandisirwo akawanda.
MaIntumescent flame retardants akasiyana nekuti anokura kana akafumurwa nekupisa, achigadzira char layer inodzivirira zvinhu zviri pasi kubva mumoto. Iyi mhando yemoto inodzoreredza kazhinji ine musanganiswa weiyo kabhoni sosi, asidhi sosi, uye inofuridza mumiriri. Kana yapiswa, iyo asidhi sosi inokonzeresa kabhoni kuti iite char, nepo iyo inofuridza ichigadzira mabhuru egasi anowedzera char layer. Iyi nzira inopa yakanakisa kudzivirira kwemoto uye inowanzoshandiswa mumachira uye mapurasitiki anochinjika.
Nepo zvinodzikisira murazvo zvichiita basa rakakosha mukusimudzira kuchengetedzwa kwemoto, kushandiswa kwavo kunosimudza zvakanyanya nharaunda uye hutano kunetseka. Mazhinji halogenated flame retardants akabatanidzwa neakaipa hutano mhedzisiro, kusanganisira endocrine kukanganisa uye nyaya dzebudiriro. Nekuda kweizvozvo, masangano anodzora ari kuwedzera kurambidza kushandiswa kwavo. Kusiyana neizvi, phosphorous uye inorganic flame retardants inowanzotorwa sedzimwe nzira dzakachengeteka, kunyangwe tsvakiridzo inoenderera ichidikanwa kuti unzwisise zvizere maitiro avo enguva refu.
Sarudzo yezvinodzosa moto mumapurasitiki zvinokanganiswa nezvinhu zvakasiyana, zvinosanganisira kushanda zvakanaka, kuchengetedzwa, uye kukanganisa kwezvakatipoteredza. Sezvo mirau ichiomesa uye kuziva kwevatengi kuchikura, indasitiri ingangoramba ichienda kune yakachengeteka, inogoneka inodzoreredza murazvo sarudzo. Kunzwisisa marudzi akasiyana-siyana emoto anodzosa uye maitiro azvo kwakakosha kune vagadziri, vatengi, uye vanogadzira mitemo zvakafanana mukutsvaga kwezvinhu zvakachengeteka.
Sichuan Taifeng New Flame Retardant Co., Ltdmugadziri ane makore makumi maviri nemaviri ehunyanzvi mukugadzirwa kweammonium polyphosphate flame retardants, zvigadzirwa zvedu zvinotengeswa kunze kwenyika zvakanyanya mhiri kwemakungwa.
Yedu inomiririra murazvo retardantTF-241ine eco-inoshamwaridzika uye ine mari, ine yakakura application muPP, PE, HEDP.
Kana uchida kuziva mamwe mashoko, tapota taura nesu.
