Ungayikhetha kanjani i-cyanurate enhle ye-melamine?

I-Melamine Cyanurate(I-MCA) iyingxenye ebalulekile esetshenziswa kabanzi embonini ye-flame retardant, ikakhulukazi efanelekile ukuguqulwa kwe-flame retardant yama-thermoplastics, njenge-nylon (PA6, PA66) nePolypropylene (PP). Imikhiqizo ye-MCA ephezulu ye-MC ingathuthukisa kakhulu izakhiwo ze-Flame Retardant zezinto zokwakha ngenkathi igcina izakhiwo zoMshini ezibonakalayo kanye nezakhiwo ezisebenzayo. Kodwa-ke, ikhwalithi yemikhiqizo ye-MCA emakethe iyahlukahluka, nokuthi ungayikhetha kanjani i-MCA esezingeni eliphezulu esephenduke inkinga ebalulekile ebhekene nabasebenzisi.

Okokuqala, qonda izici eziyisisekelo ze-cyanirate ye-melamine

I-Melamine Cyanurate iyimpuphu emhlophe noma i-granule enezakhiwo ezilandelayo:

1

2. Ukuqina okuhle okushisayo: I-MCA iqinile emazingeni okushisa aphezulu futhi ingazivumelanisa nezimo ezahlukahlukene zokucubungula.

I-3. I-non-anobuthi futhi inobuthi be-flame Retacrant:

Qonda inqubo yokukhiqiza ye-MCA

Inqubo yokukhiqiza ye-MCAkhona njengamanje izinqubo ezimbili eziphambili zokukhiqiza emakethe:

Indlela ye-urea

I-Melamine ingezwa ngesikhathi se-pyrolysis ye-urea ukukhiqiza i-ICA, noma urea kanye ne-melamine yi-eutectic ukukhiqiza i-crude mca ngesinyathelo esisodwa. I-acid abilisiwe, egeziwe, eyomile futhi ecwengekile ukuthola umkhiqizo ophelile. Izindleko zokukhiqiza ziphansi. Izindleko zezinto zokusetshenziswa ezivuthiwe zingaba ngu-70% walokho kwendlela ye-cyanuric acid.

I-Cyanuric acid indlela

Faka amanani alinganayo we-melamine ne-ICA emanzini ukwenza ukumiswa, usabele amahora amaningi ku-90-95 ° C (noma u-100-120 ° C79), qhubeka usabele isikhathi ngemuva kokuthi i-slurry ngokusobala i-viscous, bese uhlunga . , omisiwe futhi ochotshoziwe ukuthola umkhiqizo ophelile. Utshwala bamama buvuselelwa kabusha.

Naka izinkomba zekhwalithi ye-MCA

Lapho ukhetha i-MCA, udinga ukugxila ezinhlelweni zekhwalithi ezilandelayo:

 Ubumsulwa

I-Pough Phitined MCA iyisisekelo semikhiqizo yekhwalithi. Ngokuvamile, ubumsulwa be-MCA esezingeni eliphakeme kufanele bube ngaphansi kwama-99,5%. Lapho kukhuphuka ubumsulwa, okungcono kwezakhiwo zayo ze-flame retardant, ngenkathi ugwema umthelela wokungcola ezintweni ezibonakalayo.

Ubumsulwa

Lapho kukhuphuka okumhlophe, okucwengezele kakhulu ubuchwepheshe bokucubungula kwe-MCA kanye nokwehlisa okuqukethwe kokungcola. Ubumsulwa obunzima be-MCA abagcini nje ngokuthuthukisa ikhwalithi yokubukeka, kodwa futhi bavikele noma yimuphi umthelela ogwini lomkhiqizo wokuphela.

Ukusatshalaliswa kosayizi wezinhlayiyana

Usayizi nokusatshalaliswa kobukhulu bezinhlayiyana kuthinta ngqo ukuhlakazwa kanye nokusebenza kwe-MCA ku-polymer matrix. I-MCA esezingeni eliphakeme imvamisa inokusatshalaliswa kosayizi ofanayo, futhi ubukhulu bezinhlayiyana bulawulwa ngesidingo samakhasimende ngamunye (imvamisa ilingana noma ngaphansi kwama-microns noma ngaphansi kwama-micron), futhi akwazi ukuqinisekisa ukusabalalisa kepha futhi anciphise umthelela ezindaweni ezisetshenziswayo ze okuqukethwe.

Ubumanzi

I-MCA enokuqukethwe komswakama ophansi kunganciphisa ubungozi be-hydrolysis yezinto ezisetshenziswayo ze-polymer ngesikhathi sokucubungula okushisa kakhulu futhi uqinisekise ukuhlanganisa okuhle. Ukuqukethwe komswakama kwe-MCA esezingeni eliphakeme kuvame ukuba ngaphansi kwe-0,2%.

Hlaziya iziqu zomhlinzeki kanye namakhono wensiza

Ukukhetha imikhiqizo esezingeni eliphakeme ye-MCA, ngaphezu kokunaka umkhiqizo uqobo, futhi udinga ukuhlola iziqu zomhlinzeki kanye namakhono wensizakalo:

Iziqu Zokuqinisekisa

Abahlinzeki abasezingeni eliphakeme bavame ukudlula isitifiketi sohlelo lokuphathwa kohlelo lwe-ISO9001, i-ISO14001 Isitifiketi Sokulawulwa Kwezemvelo, njll. Ngaphezu kwalokho, imikhiqizo kumele ihambisane nemithetho yezemvelo yamanye amazwe njengokufinyelela.

Umthamo Wokukhiqiza Nokwesekelwa Kwezobuchwepheshe

Abahlinzeki abanezikhungo zanamuhla zokukhiqiza namaqembu e-R & D angaqinisekisa ukunikezwa okuzinzile kwemikhiqizo futhi ahlinzeke amakhasimende ngokuxhaswa kwezobuchwepheshe kanye nezixazululo.

Idumela lamakhasimende

Funda mayelana nedumela lomhlinzeki kanye namazinga enkonzo ngokubuyekezwa kwamakhasimende. Uma imikhiqizo yabahlinzeki isetshenziswa kabanzi yizinkampani ezaziwayo, ukuthembeka kwazo kanye nekhwalithi kuqinisekisiwe ngokwengeziwe.

I-Logistics nesevisi yokuthengisa ngemuva

Abahlinzeki abasezingeni eliphakeme bavame ukuba nohlelo oluphelele lwe-Logistics futhi bangaphendula ngokushesha kwizidingo zamakhasimende. Ngasikhathi sinye, kufanele futhi bahlinzeke ngensizakalo enhle yokuthengisa, kufaka phakathi ukwesekwa kwezobuchwepheshe, impendulo yenkinga, njll.

Ukuvakasha okuphakathi nendawo nokuhlolwa kwesampula

Ngaphambi kokuhlonza abahlinzeki ababambisanayo, ukuhlolwa kusayithi kuyindlela ebalulekile yokuqinisekisa amandla okukhiqiza. Ngokuvakashela ifektri, ungaqonda imishini yayo yokukhiqiza, inqubo yokugeleza kwenqubo kanye nekhwalithi yokuphatha ikhwalithi. Ngaphezu kwalokho, ukuhlolwa kwesampula nakho kuyisinyathelo esibalulekile sokuqinisekisa ukuthi umkhiqizo uhlangabezana nezidingo.

Izincomo Zokuhlola Isampula zifaka okulandelayo:

- Ukuhlaziywa kobumsulwa: Ngokuhlola ukusetshenziswa kwelebhu, qinisekisa ukuthi ubumsulwa bangempela bomkhiqizo buhlangabezana yini nezidingo.

- Ukuhlolwa kosayizi wezinhlayiyana: Ukusatshalaliswa kosayizi wezinhlayiyana kulinganiswa kusetshenziswa i-partic usayizi analyzer.

Ngemininingwane yokuhlola, ungaqonda ukusebenza komkhiqizo ngokuqondile futhi wenze izinqumo zokuthenga zesayensi.

Ngokulandela izinyathelo ezingenhla, uzokwazi ukuthola ikhwalithi ephezuluUmhlinzeki we-MCALokho kunganikeza isixazululo esizinzile se-flame retardant yephrojekthi yakho.
