Melamine Cynurate(MCA) chinhu chakakosha chinoshandiswa zvakanyanya muindasitiri inodzoreredza moto, kunyanya yakakodzera kuchinjika kwemurazvo we thermoplastics, senge nylon (PA6, PA66) uye polypropylene (PP). Zvigadzirwa zvemhando yepamusoro zveMCA zvinogona kuvandudza zvakanyanya murazvo unodzoreredza zvivakwa zvezvinhu uku uchichengetedza zvinhu zvemichina uye zvivakwa zvekugadzirisa. Nekudaro, mhando yezvigadzirwa zveMCA pamusika zvinosiyana, uye nzira yekusarudza yemhando yepamusoro MCA yave nyaya yakakosha yakatarisana nevashandisi.
Kutanga, nzwisisa zvakakosha zve melamine cyanrate
Melamine cyanrate ihupfu chena kana granule ine zvinotevera zvivakwa:
1. Excellent flame retardant performance: MCA inoburitsa inert gas uye nitrogen kuburikidza ne endothermic decomposition kuti iite heat insulation layer, iyo inhibits combustion.
2. Kugadzikana kwakanaka kwekushisa: MCA yakagadzikana pakupisa kwepamusoro uye inogona kugadzirisa kune zvakasiyana-siyana zvekugadzirisa.
3. Isiri muchetura uye inoshamwaridzana nemhoteredzo: Sechidziviriro chisina halogen-isina murazvo wemoto, MCA inowirirana nemirairo yezvemhoteredzo yepasi rose (yakadai seRoHS neREACH) uye inoshandiswa zvakanyanya mumidziyo yemagetsi neminda yemotokari.
Nzwisisa maitiro ekugadzira eMCA
Maitiro ekugadzira eMCA Parizvino pane maviri makuru ekugadzira maitiro pamusika:
Urea nzira
Melamine inowedzerwa panguva ye pyrolysis ye urea kugadzira ICA, kana urea ne melamine zviri eutectic kugadzira isina kuchena MCA mune imwe nhanho. Acid yakabikwa, yakashambidzwa, yakaomeswa uye yakanatswa kuti uwane chigadzirwa chakapedzwa. Mari yekugadzira yakaderera. Mutengo wezvinhu zvakabikwa unongova 70% yeiyo nzira yecyanuric acid.
cyanuric acid nzira
Wedzera zviyero zvakaenzana zve melamine uye ICA kumvura kuita kuturika, kuita kwemaawa akati wandei pa90-95 ° C (kana 100-120 ° C79), ramba uchiita kwenguva yakati mushure mekunge slurry yava pachena, uye sefa. . , yakaomeswa uye yakapwanyika kuti uwane chigadzirwa chakapedzwa. Doro ramai rinodzokororwa.
Teerera kune MCA's core quality zviratidzo
Paunosarudza MCA, unofanirwa kutarisa pane zvinotevera mhando zviratidzo:
Kuchena
Kuchena kwepamusoro MCA ndiyo hwaro hwezvigadzirwa zvemhando yepamusoro. Kazhinji kutaura, kuchena kwemhando yepamusoro MCA kunofanirwa kunge kuri pasi pe99.5%. Iyo yakakwirira kuchena, zviri nani iyo inodzoreredza murazvo zvinhu, uku ichidzivirira kukanganiswa kwetsvina pazvinhu zvenyama.
Kuchena
Iyo yakakwirira kuchena, iyo yakanyanya kunatsiridza tekinoroji yeMCA uye kudzikisa kusvibiswa kwemukati. Kuchena kwepamusoro kweMCA hakusi kungovandudza chimiro chekutaridzika, asiwo kunodzivirira chero kukanganisa kwemuvara wechigadzirwa chekupedzisira.
Particle size distribution
Saizi uye kugovera kwehukuru hwechikamu kunokanganisa zvakananga kupararira uye kugadzirisa mashandiro eMCA mune polymer matrix. Yepamusoro-mhando MCA inowanzo ine yunifomu particle saizi yekugovera, uye avhareji saizi inodzorwa pane zvinodiwa nevatengi (kazhinji yakaenzana kana isingasviki 4 microns), iyo isingangogone kuvimbisa kupararira asi zvakare kuderedza kukanganiswa kwezvinhu zvemuchina. zvinhu.
Unyoro
MCA ine yakaderera mwando yemukati inogona kuderedza njodzi ye hydrolysis ye polymer zvinhu panguva yepamusoro-tembiricha yekugadzirisa uye kuve nechokwadi chekuenderana. Hunyoro hwemhando yepamusoro MCA kazhinji husingasviki 0.2%.
Ongorora zvikwaniriso zvemupi uye kugona sevhisi
Kuti usarudze zvigadzirwa zvemhando yepamusoro zveMCA, pamusoro pekuteerera kune chigadzirwa pachacho, iwe unofanirwawo kuongorora zvikwaniriso zvemupi uye kugona sevhisi:
Certification qualifications
Vatengesi vemhando yepamusoro vanowanzopfuura ISO9001 quality management system certification, ISO14001 Environmental Management System certification, nezvimwewo. Pamusoro pezvo, zvigadzirwa zvinofanirwa kuenderana nemirairo yezvemamiriro ekunze epasi rese seREACH.
Kukwanisa kugadzira uye kutsigirwa kwehunyanzvi
Vatengesi vane zvivakwa zvemazuva ano zvekugadzira uye zvikwata zveR&D zvinogona kuve nechokwadi chekugadzika kwezvigadzirwa uye kupa vatengi rutsigiro rwehunyanzvi uye mhinduro.
Mutengi mukurumbira
Dzidza nezvemukurumbira wemutengesi uye nhanho dzesevhisi kuburikidza nekuongorora kwevatengi. Kana zvigadzirwa zvemutengesi zvichishandiswa zvakanyanya nemakambani anozivikanwa, kuvimbika kwavo uye hutano hwakanyanya kuvimbiswa.
Logistics uye mushure mekutengesa-basa
Vatengesi vepamusoro-soro vanowanzova nehurongwa hwekugadzirisa zvinhu uye vanogona kupindura nekukurumidza kune zvinodiwa nevatengi. Panguva imwecheteyo, ivo vanofanirwawo kupa yakanaka mushure mekutengesa sevhisi, kusanganisira tsigiro yehunyanzvi, mhinduro yedambudziko, nezvimwe.
Pa-saiti kushanya uye sampuli yekuongorora
Usati wazivisa vatengesi vemubatanidzwa, kuongororwa pasaiti inzira yakakosha yekuona kugona kwekugadzira. Nekushanyira fekitori, unogona kunzwisisa midziyo yayo yekugadzira, kuyerera kwemaitiro uye nhanho yekutonga. Pamusoro pezvo, kuyedzwa kwemuenzaniso zvakare idanho rakakosha kuona kuti chigadzirwa chinosangana nezvinodiwa.
Mienzaniso yekuyedza mazano inosanganisira zvinotevera:
-Kunatsa ongororo: Kuburikidza nekuyedza marabhoritari, simbisa kana kuchena chaiko kwechigadzirwa kunosangana nezvinodiwa.
- Particle saizi bvunzo: Particle saizi kugovera inoyerwa uchishandisa particle size analyzer.
Kuburikidza nedata rekuyedza, unogona kunzwisisa kuita kwechigadzirwa zvakanyanya uye kuita sarudzo dzekutenga kwesainzi.
Nekutevera matanho ari pamusoro apa, iwe unozokwanisa kuwana yemhando yepamusoroMutengesi we MCAiyo inogona kupa yakagadzikana murazvo retardant mhinduro yeprojekiti yako.
