Tsev neeg ntawm Halogen - nplaim hluav taws retardants, orgo organic nplaim taws reticon nplaim taws, thiab nitrogen nplaim retardants.
1, inorganic nplaim retardant
Inorganic nplaim retardants muaj qhov zoo ntawm kev ruaj khov zoo, tsis muaj kev lom zem thaum lub sij hawm cov khoom siv raw khoom, tsis muaj nqi ntawm cov nplaim hluavtaws thiab puv; Thiab ib puag ncig phooj ywg, nws yog ib tug heev kev cia siab nplaim retardant. Inorganic nplaim taws retardants tsuas yog suav nrog SB2O3, AL (Oh) 3, mg (Oh) 2, inorganic phosphorus series, thiab lwm yam.
1. Cov neeg saib xyuas trioxide
Cov neeg ua kom tus neeg saib xyuas tus kheej (SB2O3) yog qhov feem ntau siv hom inorganic nplaim retardant. Vim nws cov txiaj ntsig tsis zoo thaum siv ib leeg, nws feem ntau siv hauv kev sib xyaw nrog cov organic ntau yam kom ua tiav synergistic cuam tshuam, hu ua symernist. Nws muaj cov nplaim hluavtaws zoo heev retardant nyhuv thiab tuaj yeem siv dav hauv plastics xws li pvc, polyolefin, thiab polyester. Tab sis nws muaj cov nyhuv stimulating rau lub qhov ntswg, qhov muag, thiab caj pas. Inhalation rau hauv lub cev tuaj yeem ua rau ua rau lub cev ua pa, thiab hu rau daim tawv nqaij tuaj yeem ua rau tawv nqaij. Yuav tsum ceev faj yuav tsum tau coj thaum siv nws.
2. Aluminium hydroxide
Aluminium hydroxide Al (Oh) 3 yog feem ntau hu ua hydrated alumina. Nws yog cov hmoov dawb huv crystalline muaj 34.4% siv lead ua dej, lub cev qhuav dej ntawm qhov kub siab tshaj 200 degree, thiab tuaj yeem nqus tau ntau npaum li cas ntawm tshav kub. Ib qho ntxiv, thaum txhuas hydroxide ntxiv rau plastics, cov pa luam yeeb dawb thaum lub ntsej muag tawv nqaij dub ua rau cov pa luam yeeb dub, muab cov pa luam yeeb thiab txo cov pa luam yeeb thiab cov roj ntsha.
3. Magnesium hydroxide
Magrocesium hydroxide mg (Oh) 2 muaj cov nplaim hluav taws xob qis dua piv rau cov plastics hauv cov khoom siv loj tuaj yeem cuam tshuam rau cov tshuab kho zog. Tom qab kev kho deg nrog coupling cov neeg sawv cev, nws adhesion nrog resin tuaj yeem txhim kho, ua rau nws muaj cov nplaim taws ob leeg. Feem ntau siv hauv EP, PF, nce, ABS, PVC, PE, thiab lwm yam.
4. Inorganic phosphorus nplaim retardants
Inorganic phosphorus nplaim retardants tsuas yog xa mus rau cov phosphorus liab. Nws yog qhov siab {- Kev ua yeeb yam nplaim retardant nrog kev ua haujlwm siab, pa luam yeeb, tsis tshua muaj kuab paug thiab lwm yam nplaim taws retardant cuam tshuam. Nws tau raug siv los ua nplaim taws retardant rau ntau tshaj 20 xyoo thiab yog muaj nuj nqis heev. Nws tuaj yeem yog siv dav hauv cov ntaub ntawv polymer xws li PA, PP, PP, tus tsiaj, Abs, roj hmab tsis tshua muaj pa taws {} dawb cable, thiab lwm yam.
5. Lwm cov nplaim taws inorganic retardants
Lwm cov nplaim hluav taws xob rov qab ua rau cov nplaim hluavtaws, fawm kib (zinc muaj cov nplaim taws Feem ntau Molybdenum trioxide thiab ammonium molybdate yog siv. Tebchaws Asmeskas tau tsim muaj ammonbium dawb mem ntshav suppressants uas tuaj yeem tiv thaiv kev ua qhov kub siab tshaj 200 degree.
2, halogen -} dawb nthuav tawm nplaim taws retardant
Pes tsawg Halogen nplaim retardant (IFR) yog ib lub haloogen - nplaim hluav taws retardant mas tsim ntawm phosphorus thiab nitrogen. Nws muaj qhov zoo ntawm cov nplaim hluav taws xob rov qab, tsis muaj cov dej ntws tawm, Halogen {{free, tsis tshua muaj pa taws, thiab tsis muaj pa roj av.
IFR tsuas yog muaj peb ntu: thawj ntu yog cov kua qaub, tseem hu ua lub cev qhuav dej lossis cov pa hluav taws xob. Feem ntau inorganic acids lossis inorganic acid tebchaw, sulfuric acid, boric acid, thiab ammonfor acid, thiab ammonium polyphosphaate (app), tuaj yeem hnov nrog cov txiaj ntsig los txhawb kev tsim ntawm carbides; Qhov thib ob ntu yog hluav ncaig hluav taws xob, tseem muaj npe ua cov neeg sawv cev hluav ncaig, xws li qee cov ntsiab lus roj carboy, pentaquatherol (ib) thiab nws lub dimers thiab cov ntxaij, thiab lwm yam; Qhov thib peb yog qhov chaw siv roj,
Vim yog cov tshuaj hygroscopicity, kev sib xyaw siab, thiab qhov tsis zoo nrog cov nplaim hluav taws xob nrog cov tshuaj uas zoo ib yam los yog muab cov tshuaj uas muaj zog nrog cov nplaim hluavtaws rov qab.
3, orgophosphorus nplaim taws retardants
Ntawm ntau yam nplaim taws retardants, phosphorus raws cov nplaim taws retardants, tshwj xeeb yog cov organic phosphorus raws cov nplaim taws, nyob ib txoj haujlwm tseem ceeb. Kev tshawb fawb txog cov organic phosphorus nplaim retardants pib thaum pib ntawm lub xyoo pua no. Feem ntau cov organic phosphorus nplaim retardants muaj qhov zoo ntawm cov pa taws uas tsis tshua muaj kev sib tw ntawm cov nplaim hluav taws xob thiab muaj kev txhim kho kev txhim kho zoo. Organic phosphorus nplaim retardants xws li phosphate esters, thiab oxidized phosphorus salts, thiab oxidized phosphorus salts, thiab oxidized phosphorus salts, thiab oxidized phosphorus salts, thiab oxorolized phosphorus salts, thiab oxorized phosphorus salts, thiab oxorized phosphorus salts, thiab oxorolized phosphorus salts, thiab oxorolized phosphorus ntsev, tab sis feem ntau dav siv yog ntsev estrers thiab phosphonates.
Vim yog cov teeb meem ntawm lub tshuab hluav taws xob siab, thiab lom ntawm cov organic farame tau tsim kho yav dhau los thiab thoob ntiaj teb nyob rau xyoo tsis ntev los no, thiab muaj qee qhov muaj. Tsis tas li ntawd, nplaim taws retardants siv nitrogen thiab silicon li nplaim taws retardant ntsiab lus kuj tseem tau txais kev tiv thaiv dav dav, cov pa luam yeeb tsawg, thiab ntsuab ib puag ncig kev tiv thaiv, thiab ntsuab ib puag ncig kev tiv thaiv, thiab ntsuab ib puag ncig kev tiv thaiv zoo. Yog li ntawd, nyob rau hauv lub molecular tsim ntawm organic phosphorus nplaim retrogen tau los ntawm kev qhia cov nplaim hluav taws xob lossis cov nplaim hluavtaws tau ntau zaug los ntawm cov nplaim hluavtaws ntxiv rau cov nyhuv sygorant lossis siosphorus
BDP thiab RDP yog tshiab Halogen - dawb thiab ib puag ncig phooj ywg posphorus tsim nyob rau hauv xyoo tsis ntev los no, thiab lawv cov qauv txheej txheem muaj nyob hauv daim duab saum toj no. Piv nrog cov lig kev cai phosphorus nplaim taws, lawv muaj cov yam ntxwv ntawm cov molecular hnyav, siab tsis muaj zog, thiab cov nplaim hluav taws kub thiab hluav taws kub. BDP yog me ntsis zoo dua rau RDP hauv thermal stability thiab hydrolytic ruaj khov. Raws li cov nplaim taws ntxiv retardant, BDP feem ntau yog siv nyob rau hauv thermoplastic engining engineering enleering, polyethylene thiab ua npuas ncauj polyurethane, qhia cov nplaim hluavtaws zoo nkauj.
4, organic silicon nplaim retardant
Organic silicon nplaim retardant yog hom tshiab - melting thiab anti retripping {1} Cov nplaim taws ib puag ncig, thiab tseem muaj cov pa luam yeeb ib txwm muaj. Organic silicon nplaim retardants tsis tsuas yog xaus rau substrate nrog cov nplaim taws zoo retardant cov khoom, thiab lwm yam khoom ntawm substrate. Tam sim no, lub ntsiab ntawm organic silicon nplaim reticone resin nplaim taws retardants thiab polydimethylsiloxane nplaim taws. Cov qauv ntawm cov nplaim hluavtaws tuaj yeem ua kom ncaj qha organic sivicon nplaim taws, thiab rau cov pab pawg ua haujlwm (xws li epoxy pawg) ntawm polysiloxane ntu ib co polymers.
5, nitrogen raws nplaim retardants
Cov kev tshawb fawb ntawm cov nplaim hluav taws xob rov qab pib txij li lig, thiab tam sim no tsis muaj ntau hom siv, tsuas yog siv ntau hom. Feem ntau siv nitrogen raws cov nplaim taws retardants suav nrog melamine, tau muaj cov nplaim taws thiab muaj txiaj ntsig thiab muaj nuj nqis hauv tsev nyob rau xyoo tsis ntev los no. Raws li cov ntaub ntawv xov xwm tam sim no, kev siv Nitrogen raws cov nplaim taws uas muaj nplaim taws retardant system tsim cov nplaim hluav taws retardants muaj cov nplaim taws zoo retardant cuam tshuam.
