Ungayikhetha njani i-Melamine elungileyo ye-wilane?

I-Melamine Sceanurate. Iimveliso ezikumgangatho ophezulu we-MCA zinokuphucula kakhulu iipropathi ezihlawulelwayo zeFlethe zeZinto zeZinto ngelixa ugcina iipropathi zoomatshini bokusebenza kunye neepropathi zokulungisa. Nangona kunjalo, umgangatho weemveliso ze-MCA kwimarike iyahluka, kwaye indlela yokukhetha i-MCA ekumgangatho ophezulu ibe ngumcimbi obalulekileyo ojamelene nabasebenzisi.

Okokuqala, qonda ipropathi esisiseko ye-melamine cycurate

I-Melamine Sceanurate ngumgubo omhlophe okanye igranile enepropathi elandelayo:

I-1. I-Plamer Roomer Resordiment: I-MCA ikhuphe igesi ye-inter kunye ne-nitrogen nge-Ekothermic ye-Ekothermic ukwenza i-subser facuntrinter, ethunyelwayo.

2. Uzinzo oluhle lwe-therm

I-3. Engabinatyhefu kwaye inobuhlobo bendalo: Njengelangatye elingenasiseko le-halogn, i-MCA lihambelana nemigaqo yendalo esingqongileyo (efana ne-rohs kwaye isetyenziswe) kwaye isetyenziswe ngokubanzi kwizixhobo ze-elektroniki kunye neemoto zemoto.

Qonda inkqubo yemveliso ye-MCA

Inkqubo yemveliso ye-MCA Kukho iindlela ezimbini zemveliso eziphambili kwintengiso:

Indlela ye-Urea

I-Melamine yongezwa ngexesha le-Pyrolysis ye-ICA, okanye u-Urea kunye ne-Melamine inesifo sokuvelisa i-MCA kwinyathelo elinye kwinyathelo elinye. I-acid ibilisiwe, ihlanjwe, yomile kwaye ihlaziyiwe ukufumana imveliso egqityiweyo. Iindleko zemveliso ziphantsi. Ixabiso lezinto ezingafunekiyo zimalunga neepesenti ezingama-70 kuphela zendlela ye-Acid ye-Acid.

Indlela ye-SCyanic Acid

Yongeza izixa ezilinganayo zeMelamine kunye ne-ICA ukuya emanzini ukwenza umnyhawulo, uqhubeke iiyure ezininzi nge-90-95 ° C (okanye i-7) ° C79), qhubeka usabela ixesha lokutyibilika, kwaye i-filter . , womile kwaye watyunyuzwa ukuze afumane imveliso egqityiweyo. Utywala bukamama buhlaziyiwe kwakhona.

Nika ingqalelo kwiimpawu ezisemgangathweni zeMCA

Xa ukhetha i-MCA, kufuneka ugxile kwezi zikhombisi zimgangatho zilandelayo:

 Ubunyulu

UPulty oPulsity MCA sisiseko seemveliso ezisemgangathweni. Ngokubanzi, ukucoceka kwe-MCA ekumgangatho ophezulu kufanele ukuba kungabikho ngaphantsi kwe-99.5%. Ukuphakama kubunyulu, ngcono iipropathi zayo ezihlawulayo, ngelixa ziphepha ifuthe lokungcola kwizinto ezibonakalayo.

Imhlophe

Ukuphakama kobumhlophe, kokukhona itekhnoloji yokuqhubela phambili ye-MCA kunye nezantsi komxholo ongaphantsi. Ubumhlophe obuphezulu be-MCA abuphucuphuli kuphela umgangatho wokubonakala, kodwa kukuthintela naliphi na impembelelo kumbala wemveliso yokuphela.

Ubungakanani bobungakanani bentsundu

Ubungakanani kunye nokusasazwa kobungakanani be-paunticle kuchaphazela ngokuthe ngqo ukusasazeka kunye nokusebenza kwe-MCA kwi-polymer matrix. I-MCA ekumgangatho ophezulu idla ngokusasazwa kwe-iyunifomu, kwaye ubungakanani obuqhelekileyo bulawulwa ngemfuno yabathengi (ihlala ilingana okanye ingaphantsi kwe-4 microns) kuphela, ikwazi ukunciphisa impembelelo kwiipropathi zoomatshini be umxholo.

Ukufuma

I-MCA enemixholo yokufuma ephantsi inokunciphisa umngcipheko we-hydrolysis yezixhobo ze-polymer ngexesha lokulungisa ubushushu kwaye kuqinisekiswe ukubaluleka. Umxholo wokufuma kwe-MCA ekumgangatho ophezulu we-MCA uhlala ungaphantsi kwe-0.2%.

UVAVANYO LWEZAKHONO ZABASEBENZI NOKUFUNDA

Ukukhetha iimveliso ezisemgangathweni ze-MCA, ukongeza ekunikeleni ingqalelo kwimveliso ngokwayo, kuya kufuneka uhlole iziqinisekiso zomthengisi kunye nezakhono zenkonzo:

Isiqinisekiso sokuqinisekiswa

Isatifikethi esikumgangatho ophezulu sidlule kwisiqinisekiso senkqubo ye-ISO90000 yolawulo lwendalo, njl. Ukongeza, iimveliso kufuneka zihambelane nemigaqo yendalo esingqongileyo efana nokufikelela.

Umthamo wemveliso kunye nenkxaso yezobugcisa

Abathengisi abanamaziko emveliso yanamhlanje kunye namaqela e-R & D anokuqinisekisa ukuhanjiswa kwezinzile kwaye banike abathengi ngenkxaso yezobugcisa kunye nezisombululo.

Udumo lwabathengi

Funda malunga nengxelo yomthengisi kunye nenqanaba lenkonzo ngokuhlolwa kwabathengi. Ukuba iimveliso zomthengisi zisetyenziswa ngokubanzi ziinkampani ezaziwayo, ukuthembeka kwabo kunye nomgangatho kuqinisekisiwe ngakumbi.

Izixhobo kunye nenkonzo yasemva kwentengiso

Abathengisi abakumgangatho ophezulu bahlala benenkqubo epheleleyo yezinto kwaye banokuphendula ngokukhawuleza kwiimfuno zabathengi. Kwangelo xesha, kufuneka banikezele ngenkonzo elungileyo yasemva kwentengiso, kubandakanya nenkxaso yezobugcisa, ingxelo yengxaki, njl.

Ukutyelelwa kwesiza kunye novavanyo lwesampulu

Ngaphambi kokuba ichonge abathengisi abaphetheyo, uhlolo lwendawo yindlela ebalulekileyo yokuqinisekisa amandla emveliso. Ngokutyelela umzi-mveliso, ungasiqonda izixhobo zayo zemveliso, ukuhamba kwenkqubo kunye nenqanaba lolawulo lomgangatho. Ukongeza, uvavanyo lwesampulu likwalinyathelo elibalulekileyo lokuqinisekisa ukuba imveliso ihlangabezana neemfuno.

Iingcebiso zovavanyo lwesampulu zibandakanya oku kulandelayo:

-Uhlalutyo lokucoceka: ngovavanyo lwelebhu, qinisekisa ukuba icoceko yemveliso ihlangabezana neemfuno.

I-paricle ubungakanani bovavanyo: Ukuhanjiswa kwesuntswana kulinganiswa kusetyenziswa i-hlalutelical yolwazi.

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

Ngokulandela la manyathelo angasentla, uya kuba nakho ukufumana umgangatho ophezuluUmboneleli we-MCAinokubonelela ngesisombululo esizinzileyo seflethi yeProjekthi yakho.
