Uwukhetha njani uMgangatho oLungileyo weMelamine Cyanrate?

Khetha-MCA

I-Melamine Cynurate(i-MCA) iyikhompawundi ebalulekileyo esetyenziswa ngokubanzi kwi-industry ye-flame retardant, ngokukodwa ilungele ukuguqulwa kwe-flame retardant ye-thermoplastics, njenge-nylon (PA6, i-PA66) kunye ne-polypropylene (PP). Iimveliso ezikumgangatho ophezulu we-MCA zinokuphucula ngokubonakalayo iipropathi zokunqanda ilangatye zemathiriyeli ngelixa ugcina iipropathi zoomatshini kunye neepropathi zokucubungula. Nangona kunjalo, umgangatho weemveliso ze-MCA kwimarike uyahluka, kwaye indlela yokukhetha i-MCA ephezulu ibe ngumba obalulekileyo ojongene nabasebenzisi.

Okokuqala, qonda iimpawu ezisisiseko ze-melamine cyanrate

I-Melamine cyanrate ngumgubo omhlophe okanye igranule eneempawu ezilandelayo:

1. Ukusebenza okugqwesileyo kwedangatye: I-MCA ikhupha igesi engasebenziyo kunye nenitrogen ngokubola kwe-endothermic ukwenza umaleko wokugquma ubushushu, othintela ukutsha.

2. Uzinzo oluhle lwe-thermal: I-MCA izinzile kumaqondo aphezulu kwaye iyakwazi ukulungelelanisa kwiimeko ezahlukeneyo zokucwangcisa.

3. I-Non-toxic and Environmental friendly: Njenge-halogen-free flame retardant, i-MCA ithobela imimiselo yendalo engqongileyo yamazwe ngamazwe (efana ne-RoHS kunye ne-REACH) kwaye isetyenziswa ngokubanzi kwizixhobo zombane kunye neendawo zemoto.

 

Qonda inkqubo yemveliso ye-MCA

Inkqubo yemveliso ye-MCA Okwangoku kukho iinkqubo ezimbini eziphambili zemveliso kwimarike:

Indlela yeUrea

I-Melamine yongezwa ngexesha le-pyrolysis ye-urea ukuvelisa i-ICA, okanye i-urea kunye ne-melamine i-eutectic ukuvelisa i-MCA ekrwada kwinqanaba elinye. I-Acid ibilisiwe, ihlanjwe, yomiswe kwaye ihlanjululwe ukufumana imveliso egqityiweyo. Iindleko zemveliso ziphantsi. Iindleko zemathiriyeli ekrwada kuphela malunga ne-70% yendlela ye-cyanuric acid.

indlela ye-cyanuric acid

Yongeza inani elilinganayo le-melamine kunye ne-ICA kumanzi ukwenza ukumiswa, ukusabela kwiiyure ezininzi kwi-90-95 ° C (okanye i-100-120 ° C79), qhubeka usabela ixesha elide emva kokuba i-slurry ibonakale ngokucacileyo, kwaye ihluzo. . , yomisiwe kwaye icolile ukufumana imveliso egqityiweyo. Utywala lukamama luyarisayikilishwa.

 

Nika ingqalelo kwizalathi zomgangatho ongundoqo we-MCA

Xa ukhetha i-MCA, kufuneka ugxininise kwezi zalathisi zomgangatho zilandelayo:

 Ubunyulu

Ukucoceka okuphezulu kwe-MCA sisiseko seemveliso ezisemgangathweni. Ngokubanzi, ukucoceka kwe-MCA ekumgangatho ophezulu kufuneka kungabi ngaphantsi kwe-99.5%. Ukuphakama kobunyulu, bhetele iimpawu zayo zokunqanda ilangatye, ngelixa uphepha impembelelo yokungcola kwizinto eziphathekayo.

Ubumhlophe

Okukhona ubumhlophe buphezulu, kokukhona bucokisekileyo ngakumbi iteknoloji yokusetyenzwa kwe-MCA kunye nokuthoba umxholo wokungcola. Ubumhlophe obuphezulu be-MCA abuphuculanga kuphela umgangatho wokubonakala, kodwa kwakhona ugwema nayiphi na impembelelo kumbala wemveliso yokugqibela.

Ukuhanjiswa kobungakanani besuntswana

Ubungakanani kunye nokuhanjiswa kwesayizi ye-particle kuchaphazela ngokuthe ngqo ukusabalalisa kunye nokusebenza kwe-MCA kwi-matrix ye-polymer. Umgangatho ophezulu we-MCA udla ngokusasazwa kobungakanani bamasuntswana afanayo, kwaye ubungakanani bamasuntswana aqhelekileyo bulawulwa ngokwemfuno yabathengi (ngokuqhelekileyo ilingana okanye ngaphantsi kwe-microns ezi-4), ezingenakuqinisekisa kuphela ukusasazwa kodwa nokunciphisa impembelelo kwiipropati zoomatshini. izinto eziphathekayo.

Ukufuma

I-MCA enomxholo ophantsi wokufuma inokunciphisa umngcipheko we-hydrolysis yezinto ze-polymer ngexesha lokulungiswa kobushushu obuphezulu kunye nokuqinisekisa ukuhambelana kwe-excellet. Isiqulatho sokufuma se-MCA esikumgangatho ophezulu sikholisa ukuba ngaphantsi kwe-0.2%.

 

Ukuvavanya iziqinisekiso zomboneleli kunye nobuchule benkonzo

Ukukhetha iimveliso ze-MCA ezikumgangatho ophezulu, ukongeza ekunikeleni ingqalelo kwimveliso ngokwayo, kuya kufuneka ujonge iziqinisekiso zomboneleli kunye nobuchule benkonzo:

Iziqinisekiso zesatifikethi

Ababoneleli abakumgangatho ophezulu badla ngokupasa isatifikethi se-ISO9001 senkqubo yolawulo lomgangatho, isiqinisekiso senkqubo yolawulo lwemo engqongileyo ISO14001, njalo njalo. Ukongeza, iimveliso kufuneka zihambelane nemigaqo yokusingqongileyo yamazwe ngamazwe efana neREACH.

Umthamo wemveliso kunye nenkxaso yobugcisa

Ababoneleli abanezixhobo zanamhlanje zokuvelisa kunye namaqela e-R&D anokuqinisekisa unikezelo oluzinzileyo lweemveliso kunye nokubonelela abathengi ngenkxaso yobugcisa kunye nezisombululo.

Isidima somthengi

Funda malunga nodumo lomboneleli kunye namanqanaba enkonzo ngokuphononongwa kwabathengi. Ukuba iimveliso zomboneleli zisetyenziswa ngokubanzi ziinkampani ezaziwayo, ukuthembeka kwabo kunye nomgangatho kuqinisekiswa ngakumbi.

Ulungiselelo kunye nenkonzo emva-kwentengiso

Ababoneleli abakumgangatho ophezulu badla ngokuba nenkqubo epheleleyo yolungiselelo kwaye banokusabela ngokukhawuleza kwiimfuno zabathengi. Ngexesha elifanayo, kufuneka babonelele ngenkonzo efanelekileyo emva kokuthengisa, kubandakanywa nenkxaso yobugcisa, impendulo yengxaki, njl.

Utyelelo kwisiza kunye novavanyo lwesampulu

Phambi kokuchonga ababoneleli ngentsebenziswano, uhlolo olukwisiza luyindlela ebalulekileyo yokuqinisekisa ubunakho bemveliso. Ngokundwendwela umzi-mveliso, unokuqonda izixhobo zayo zokuvelisa, ukuhamba kwenkqubo kunye nenqanaba lolawulo lomgangatho. Ukongeza, uvavanyo lwesampulu lukwalinyathelo elibalulekileyo lokuqinisekisa ukuba imveliso iyahlangabezana neemfuno.

Iingcebiso zovavanyo lwesampulu ziquka oku kulandelayo:

- Uhlalutyo lokucoceka: Ngovavanyo lwebhubhoratri, qinisekisa ukuba ukucoceka kwangempela kwemveliso kuyahlangabezana neemfuno.

– Uvavanyo lobungakanani besuntswana: Ukuhanjiswa kobungakanani besuntswana kulinganiswa kusetyenziswa i-particle size analyzer.

Ngedatha yovavanyo, unokuqonda ukusebenza kwemveliso ngakumbi kwaye wenze izigqibo zokuthenga zesayensi.

 

Ngokulandela la manyathelo angasentla, uya kuba nako ukufumana umgangatho ophezuluUmthengisi we-MCAenokubonelela ngesisombululo esizinzileyo sedangatye leprojekthi yakho.
