Nyob rau hauv ib lub caij nyoog uas muaj kev nyab xeeb thiab cov cai yog qhov tseem ceeb tshaj plaws, kev txhim kho cov ntaub ntawv uas tiv thaiv hluav taws tau dhau los ua kev lag luam tseem ceeb ntawm ntau yam kev lag luam. Ntawm cov kev hloov tshiab no, nplaim taws retardant masterback tebchaw tau tshwm sim raws li kev daws teeb meem ntse los txhim kho cov hluav taws kub tiv thaiv cov polymers.
To kev nkag siab dab tsi yog nplaim retardant masterbatch tebchaw?
Nplaim retardant masterbatch tebchaw yog cov qauv tshwj xeeb tsim los pov cov hluav taws-resistant cov khoom siv rau cov polymers. Cov tebchaw no muaj cov cab kuj, uas ib txwm muaj tib lub polymer raws li cov khoom siv hauv paus, thiab nplaim taws retardant ntxiv. Cov cab kuj resin ua hauj lwm ua qhov nruab nrab rau dispersing cov nplaim taws retardant tus neeg sawv cev thoob plaws lub polymer matrix.
Cheebtsam ntawm nplaim taws retardant masterback tebchaw:
1. Carrier resin:
Cov cab kuj resin ua cov ntawv ntawm masterbatch thiab yog xaiv raws li kev sib raug zoo nrog lub hauv paus polymer. Cov resins uas muaj cov polyethylene (PE), polypropylene (pp), polyvinyl chloride (PVC), thiab lwm qhov thermoplastics. Qhov kev xaiv ntawm Carrier resin yog qhov tseem ceeb los xyuas kom ua tau zoo dispersion thiab sib xyaw nrog lub hom phiaj polymer.
2. Nplaim taws retardant additives:
Nplaim taws retardant additives yog cov khoom xyaw nquag ua rau lub luag haujlwm ua rau muaj kev cuam tshuam lossis ncua kev sib kis taws. Yeej, nplaim taws retardants tuaj yeem ua kom rov qab los yog additive. Cov tshuaj ntxiv no tuaj yeem faib ua ntau hom, suav nrog cov sib txuas halogenated, phosphorus-based tebchaw, thiab cov pob zeb hauv av. Txhua pawg muaj nws cov qauv tshwj xeeb ntawm kev nqis tes ua hauv kev tsim txom cov txheej txheem combation.
2.1 halogenated tebchaw: brominated thiab chlorinated tebchaw Halogen radicals thaum kev cuam tshuam nrog cov kev sib txuas ua ke cov tshuaj tiv thaiv.
2.2 phosphorus-raws li cov tebchaw: Cov tebchaw tso tawm cov kua qaub posphoric acid thaum lub sijhawm sib txuas, tsim cov txheej tiv thaiv uas suppresses cov nplaim taws.
2.3 filleal filleters: inorganic fillers zoo li txhuas hydroxide thiab nthuav tawm cov khoom cua sov, cua txias cov khoom thiab diluting cov pa roj av.
3. Cov ntsaws thiab txhawb ntxiv:
Fillers, xws li tanc lossis calcium carbon lossis calcium carbonate, feem ntau ntxiv ntxiv txhim kho cov khoom siv tshuab ntawm masterbatch sib txuas. Kev txhawb nqa txhim kho nruj zog, lub zog, thiab seem ruaj khov, ua rau muaj kev ua tau zoo ntawm cov khoom siv.
4. Stabilizers:
Steeilizers tau sib xyaw los tiv thaiv kom tsis txhob muaj kev cuam tshuam ntawm cov polymer matrix thaum siv thiab siv. Antioxidants thiab UV Stabilizers, piv txwv, pab kom muaj cov khoom siv ncaj ncees thaum pom ib puag ncig cov khoom.
5.Cov thiab pigments:
Nyob ntawm daim ntawv thov, cov duab thiab cov pigments tau ntxiv rau impart cov xim tshwj xeeb rau daim masterbatch sib txuas. Cov khoom siv no tseem tuaj yeem cuam tshuam rau cov khoom siv tshuaj loog.
6. Cov Txheeb Xyuas:
Nyob rau hauv cases qhov twg nplaim retardant thiab polymer matrix ua rau pom kev sib xyaw tsis zoo, cov ntawv sau ua haujlwm tau ua haujlwm. Cov tshuaj tiv thaiv no txhim kho kev sib cuam tshuam ntawm cov cheebtsam, txhawb kev faib tawm zoo dua thiab kev ua tau zoo tag nrho.
7.smoke suppressants:
Cov pa luam yeeb, xws li zinc borate lossis molybdenum tebchaw, qee zaum suav nrog kev haus luam yeeb thaum kev sib txuas, ib qho tseem ceeb hauv kev siv hluav taws.
8. Ntxiv rau kev ua:
Ua kev pabcuam ntxiv raws li cov roj nplua thiabDispersing cov neeg sawv cevpab txhawb kev tsim khoom. Cov tshuaj ntxiv no ua kom pom kev du, tiv thaiv agglomeration, thiab pab ua kom tiav cov kev sib cais ntawm cov nplaim hluav taws.
Qhov saum toj no yog txhua yam ntawm cov nplaim taws retardant masterbatch tebchaw, thaum ua kom muaj kev faib tawm ntawm cov nplaim hluav taws xob tsis pub dhau lub ntsej muag zoo nkauj yog qhov tseem ceeb ntawm lawv txoj kev ua tau zoo. Kev rho tawm tsis txaus tuaj yeem ua rau tsis muaj kev tiv thaiv, muaj kev cuam tshuam cov khoom siv, thiab txo hluav taws kub kom nyab xeeb.
Yog li, nplaim retardant masterbatch teb feem ntau yuav tsum taudispersantsTxhawm rau daws cov nyom cuam tshuam nrog kev sib cais ntawm cov nplaim hluav taws retardant retardant tus neeg sawv cev hauv lub polymer matrix.
Tshwj xeeb tshaj yog nyob rau hauv lub yeej realm ntawm polymer science, qhov kev thov rau cov khoom tawg ua kom zoo dua qub cov khoom lag luam tau txais kev txhim kho zoo dua hauv kev sib ntxiv thiab hloov kho. Ntawm cov kev daws teeb meem trailbazing,hyperdispersantstau tshwm sim raws li cov tseem ceeb ntawm cov kev cov nyom ntawm kev ua tiav cov kev faib tawm zoo tshaj plaws hauv nplaim retardant masterbatch compound formated.
As hyperdispersantsHais qhov kev sib tw no los ntawm kev txhawb nqa txoj kev faib tawm thiab cov khoom sib txuam ntawm cov nplaim hluav taws retardants thoob plaws hauv cov masterbatch sib txuas.
