Melamine Cyanurate(MCA) ndi chinthu chofunika kwambiri chomwe chimagwiritsidwa ntchito kwambiri pamakampani oletsa moto, makamaka oyenera kusinthika kwamalawi a thermoplastics, monga nayiloni (PA6, PA66) ndi polypropylene (PP). Zogulitsa zapamwamba za MCA zimatha kusintha kwambiri zinthu zomwe zimawotcha moto ndikusunga zinthu zamakina ndi kukonza zinthu. Komabe, mtundu wa zinthu za MCA pamsika umasiyanasiyana, komanso momwe mungasankhire MCA yapamwamba yakhala nkhani yofunika kwambiri yomwe ogwiritsa ntchito amakumana nayo.
Choyamba, kumvetsetsa zofunikira za melamine cyanrate
Melamine cyanrate ndi ufa woyera kapena granule wokhala ndi zotsatirazi:
1. Kuchita bwino kwambiri koletsa moto: MCA imatulutsa mpweya wa inert ndi nayitrogeni kudzera mu kuwonongeka kwa endothermic kupanga wosanjikiza wotsekereza kutentha, womwe umalepheretsa kuyaka.
2. Kukhazikika kwabwino kwa kutentha: MCA imakhala yokhazikika pa kutentha kwambiri ndipo imatha kusinthika kuzinthu zosiyanasiyana zogwirira ntchito.
3. Zopanda poizoni komanso zachilengedwe: Monga choletsa moto wa halogen wopanda halogen, MCA imagwirizana ndi malamulo apadziko lonse a zachilengedwe (monga RoHS ndi REACH) ndipo imagwiritsidwa ntchito kwambiri pazida zamagetsi ndi minda yamagalimoto.
Kumvetsetsa njira yopanga MCA
Kapangidwe ka MCA Pakali pano pali njira ziwiri zazikulu zopangira pamsika:
Njira ya urea
Melamine amawonjezedwa pa pyrolysis wa urea kupanga ICA, kapena urea ndi melamine ndi eutectic kupanga yaiwisi MCA mu sitepe imodzi. Acid yophika, kutsukidwa, zouma ndi zoyengedwa kuti mupeze chomaliza. Ndalama zopangira ndizochepa. Mtengo wa zinthu zopangira ndi pafupifupi 70% ya njira ya cyaniric acid.
njira ya cyaniric acid
Onjezani milingo yofanana ya melamine ndi ICA m'madzi kuti muyimitsidwe, kuchitapo kanthu kwa maola angapo pa 90-95 ° C (kapena 100-120 ° C79), pitilizani kuchitapo kanthu kwa nthawi pambuyo poti slurry imakhala yowoneka bwino, ndi fyuluta. . , zouma ndi zophwanyidwa kuti mupeze chomaliza. Mowa wamayiwo umapangidwanso.
Samalani ndi zizindikiro zazikulu za MCA
Posankha MCA, muyenera kuyang'ana pazizindikiro zotsatirazi:
Chiyero
High chiyero MCA ndiye maziko a zinthu zabwino. Nthawi zambiri, kuyera kwa MCA wapamwamba kwambiri kuyenera kukhala kosachepera 99.5%. The apamwamba chiyero, bwino malawi retardant katundu, pamene kupewa zotsatira za zonyansa pa katundu katundu.
Kuyera
Kuyera kwapang'onopang'ono kumapangitsanso luso laukadaulo la MCA ndikutsitsa zonyansa. Kuyera kwakukulu kwa MCA sikumangowonjezera maonekedwe, komanso kumapewa kukhudza kulikonse pa mtundu wa mapeto.
Kugawa kukula kwa tinthu
Kukula ndi kugawa tinthu kukula mwachindunji zimakhudza kubalalitsidwa ndi processing ntchito ya MCA mu polima masanjidwewo. MCA wapamwamba kwambiri amakhala ndi yunifolomu tinthu kukula kugawa, ndi pafupifupi tinthu kukula zimalamulidwa pa zosowa makasitomala '(nthawi zambiri ofanana kapena zosakwana 4 microns), amene sangathe kuonetsetsa kubalalitsidwa komanso kuchepetsa zotsatira pa makina katundu wa. zinthu.
Chinyezi
MCA yokhala ndi chinyezi chochepa imatha kuchepetsa chiopsezo cha hydrolysis ya zinthu za polima panthawi yotentha kwambiri ndikuonetsetsa kuti imagwirizana. Chinyezi chapamwamba cha MCA nthawi zambiri chimakhala chochepera 0.2%.
Unikani ziyeneretso za ogulitsa ndi kuthekera kwautumiki
Kuti musankhe zinthu zapamwamba kwambiri za MCA, kuwonjezera pa kulabadira zomwe mumagulitsa, muyeneranso kuyang'ana ziyeneretso za omwe amapereka komanso kuthekera kwake:
Ziyeneretso za satifiketi
Otsatsa apamwamba nthawi zambiri amadutsa chiphaso cha ISO9001 kasamalidwe kabwino kazinthu, satifiketi ya ISO14001 yoyang'anira zachilengedwe, ndi zina zambiri. Kuphatikiza apo, zinthu ziyenera kutsatira malamulo apadziko lonse lapansi achilengedwe monga REACH.
Mphamvu zopanga ndi chithandizo chaukadaulo
Otsatsa omwe ali ndi zida zamakono zopangira ndi magulu a R&D amatha kuwonetsetsa kuti zinthu zili bwino ndikupatsa makasitomala chithandizo chaukadaulo ndi mayankho.
Mbiri yamakasitomala
Phunzirani za mbiri ya ogulitsa ndi kuchuluka kwa ntchito zake kudzera mu ndemanga zamakasitomala. Ngati katundu wa ogulitsa amagwiritsidwa ntchito kwambiri ndi makampani odziwika bwino, kudalirika kwawo ndi khalidwe lawo ndizotsimikizika.
Logistics ndi pambuyo-malonda utumiki
Othandizira apamwamba nthawi zambiri amakhala ndi dongosolo lathunthu lazinthu ndipo amatha kuyankha mwachangu pazosowa zamakasitomala. Nthawi yomweyo, akuyeneranso kupereka chithandizo chabwino pambuyo pogulitsa, kuphatikiza chithandizo chaukadaulo, mayankho amavuto, ndi zina.
Kuyendera pamasamba ndi kuyesa zitsanzo
Musanayambe kuzindikiritsa ogulitsa ma cooperative, kuyang'ana pamasamba ndi njira yofunikira yotsimikizira kuthekera kopanga. Poyendera fakitale, mutha kumvetsetsa zida zake zopangira, kuyenda kwa njira komanso kasamalidwe kabwino. Kuphatikiza apo, kuyesa kwachitsanzo ndi gawo lofunikira kuti muwonetsetse kuti chinthucho chikukwaniritsa zofunikira.
Zitsanzo zoyezetsa ziyeneretso ndi izi:
- Kusanthula kwachiyero: Kupyolera mu kuyesa kwa labotale, tsimikizirani ngati kuyera kwenikweni kwa chinthucho kumakwaniritsa zofunikira.
- Mayeso a kukula kwa tinthu: Kugawa kwa tinthu kumayesedwa pogwiritsa ntchito chowunikira kukula kwa tinthu.
Kudzera mu data yoyeserera, mutha kumvetsetsa momwe zinthu zimagwirira ntchito komanso kupanga zisankho zasayansi pogula.
Potsatira masitepe pamwamba, mudzatha kupeza apamwambaMtengo wa MCAzomwe zingapereke yankho lokhazikika loletsa moto pantchito yanu.
