Melamine Cyanurate(MCA) yog ib qho tseem ceeb uas siv dav hauv kev lag luam nplaim hluav taws xob, tshwj xeeb tshaj yog tsim rau cov nplaim hluav taws kub hloov pauv ntawm cov thermoplastics, xws li nylon (PA6, PA66) thiab polypropylene (PP). Cov khoom zoo MCA tuaj yeem txhim kho cov nplaim hluav taws xob zoo ntawm cov ntaub ntawv thaum tswj cov khoom siv kho tshuab thiab cov khoom ua haujlwm. Txawm li cas los xij, qhov zoo ntawm MCA cov khoom lag luam sib txawv, thiab yuav ua li cas xaiv MCA zoo tau dhau los ua qhov teeb meem tseem ceeb ntawm cov neeg siv.
Ua ntej, nkag siab txog cov yam ntxwv ntawm melamine cyanurate
Melamine cyanurate yog hmoov dawb los yog granule nrog cov khoom hauv qab no:
1. Kev ua tau zoo ntawm cov nplaim hluav taws xob zoo: MCA tso tawm cov pa roj thiab nitrogen los ntawm cov txheej txheem endothermic decomposition los tsim cov txheej txheem cua sov, uas inhibits combustion.
2. Zoo thermal stability: MCA ruaj khov ntawm qhov kub thiab txias thiab tuaj yeem hloov mus rau ntau yam kev ua haujlwm.
3. Tsis muaj tshuaj lom thiab zoo ib puag ncig: Raws li cov nplaim hluav taws tsis muaj halogen, MCA ua raws li kev cai thoob ntiaj teb ib puag ncig (xws li RoHS thiab REACH) thiab siv dav hauv cov khoom siv hluav taws xob thiab tsheb.
Nkag siab txog cov txheej txheem tsim khoom ntawm MCA
Cov txheej txheem tsim khoom ntawm MCA Tam sim no muaj ob txoj haujlwm tseem ceeb ntawm kev ua lag luam:
Txoj kev Urea
Melamine ntxiv thaum lub sij hawm pyrolysis ntawm urea los tsim ICA, los yog urea thiab melamine yog eutectic los tsim MCA crude nyob rau hauv ib kauj ruam. Acid boiled, ntxuav, qhuav thiab refined kom tau cov khoom tiav. Cov nqi tsim khoom tsawg. Tus nqi ntawm cov khoom siv raw tsuas yog kwv yees li 70% ntawm cov txheej txheem cyanuric acid.
txoj kev cyanuric acid
Ntxiv cov khoom sib npaug ntawm melamine thiab ICA rau dej kom ua rau ncua kev kawm, hnov mob rau ob peb teev ntawm 90-95 ° C (los yog 100-120 ° C79), txuas ntxiv mus rau lub sijhawm tom qab cov slurry ua kom pom tseeb, thiab lim. . , qhuav thiab crushed kom tau cov khoom tiav. Cov cawv niam yog rov siv dua.
Ua tib zoo saib rau MCA cov cim qhia tau zoo
Thaum xaiv ib qho MCA, koj yuav tsum tsom mus rau cov kev ntsuas zoo hauv qab no:
Purity
High purity MCA yog lub hauv paus rau cov khoom zoo. Feem ntau hais lus, purity ntawm high-zoo MCA yuav tsum tsis pub tsawg tshaj 99.5%. Qhov siab dua qhov purity, qhov zoo dua nws cov nplaim retardant zog, thaum zam kev cuam tshuam ntawm impurities ntawm cov khoom siv.
Dawb
Qhov siab dua qhov whiteness, ntau refined thev naus laus zis ntawm MCA thiab cov ntsiab lus impurity qis dua. Lub siab dawb ntawm MCA tsis tsuas yog txhim kho cov tsos zoo, tab sis kuj zam kev cuam tshuam rau cov xim ntawm cov khoom kawg.
Particle loj faib
Qhov loj thiab kev faib tawm ntawm qhov loj me ncaj qha cuam tshuam rau kev tawg thiab kev ua haujlwm ntawm MCA hauv polymer matrix. Cov khoom zoo MCA feem ntau muaj qhov sib txawv ntawm qhov loj me me, thiab qhov nruab nrab qhov loj me yog tswj tau raws li cov neeg siv khoom xav tau (feem ntau sib npaug los yog tsawg dua 4 microns), uas tuaj yeem tsis tsuas yog ua kom muaj kev sib cais tab sis kuj txo qhov cuam tshuam ntawm cov khoom siv kho tshuab. cov khoom.
Moisture
MCA uas tsis muaj cov ntsiab lus noo noo tuaj yeem txo qhov kev pheej hmoo ntawm hydrolysis ntawm cov ntaub ntawv polymer thaum lub sijhawm ua haujlwm kub thiab ua kom muaj kev sib raug zoo. Cov dej noo ntawm cov khoom zoo MCA feem ntau yog tsawg dua 0.2%.
Txheeb xyuas cov khoom tsim nyog thiab kev pabcuam
Txhawm rau xaiv cov khoom lag luam zoo MCA, ntxiv rau kev saib xyuas cov khoom nws tus kheej, koj kuj yuav tsum tau tshuaj xyuas cov khoom tsim nyog thiab kev pabcuam:
Daim ntawv pov thawj kev tsim nyog
Cov khoom lag luam zoo feem ntau tau dhau ISO9001 kev tswj hwm kev tswj hwm kev lees paub, ISO14001 ib puag ncig kev tswj hwm kev lees paub, thiab lwm yam. Tsis tas li ntawd, cov khoom yuav tsum ua raws li kev cai thoob ntiaj teb ib puag ncig xws li REACH.
Muaj peev xwm ntau lawm thiab kev txhawb nqa
Cov neeg muag khoom nrog cov chaw tsim khoom niaj hnub thiab R & D pab pawg tuaj yeem ua kom ruaj khov ntawm cov khoom thiab muab cov neeg siv khoom nrog kev txhawb nqa thiab kev daws teeb meem.
Cov neeg siv khoom lub koob npe nrov
Kawm txog tus neeg muag khoom lub koob npe nrov thiab qib kev pabcuam los ntawm kev tshuaj xyuas cov neeg siv khoom. Yog tias tus neeg muag khoom cov khoom siv dav siv los ntawm cov tuam txhab paub zoo, lawv txoj kev ntseeg siab thiab kev ua tau zoo yog lav ntau dua.
Logistics thiab kev pab cuam tom qab muag
Cov neeg muag khoom zoo feem ntau muaj kev ua tiav logistics thiab tuaj yeem teb tau sai rau cov neeg siv khoom xav tau. Nyob rau tib lub sijhawm, lawv yuav tsum tau muab kev pabcuam zoo tom qab muag, suav nrog kev txhawb nqa, kev tawm tswv yim teeb meem, thiab lwm yam.
Kev mus xyuas ntawm qhov chaw thiab kev sim ua qauv
Ua ntej txheeb xyuas cov neeg muab kev koom tes, kev tshuaj xyuas ntawm qhov chaw yog ib qho tseem ceeb los xyuas cov peev txheej tsim khoom. Los ntawm kev mus xyuas lub Hoobkas, koj tuaj yeem nkag siab nws cov khoom siv ntau lawm, cov txheej txheem ntws thiab qib kev tswj hwm zoo. Tsis tas li ntawd, kev kuaj cov qauv kuj yog ib kauj ruam tseem ceeb los xyuas kom meej tias cov khoom ua tau raws li qhov yuav tsum tau ua.
Cov lus pom zoo rau kev xeem muaj xws li hauv qab no:
- Kev tsom xam purity: Los ntawm kev kuaj sim, paub meej tias qhov tseeb purity ntawm cov khoom ua tau raws li qhov yuav tsum tau ua.
- Particle size test: Particle size distribution is measured siv lub particle size analyzer.
Los ntawm kev sim cov ntaub ntawv, koj tuaj yeem nkag siab txog cov khoom lag luam ua tau zoo dua thiab ua rau kev txiav txim siab yuav khoom.
Los ntawm ua raws li cov kauj ruam saum toj no, koj yuav nrhiav tau ib tug high-zooMCA tus neeg muag khoomuas tuaj yeem muab cov nplaim hluav taws kub ruaj khov rau koj qhov project.
