Intshayelelo
I-Melamine (i-chemical formula C3H6N6) yi-organic compound eneempawu ezahlukeneyo kunye nokusetyenziswa.
Umgangatho:
1. Iimpawu ezibonakalayo: I-Melamine yikristale engenambala eqinileyo kunye namanqaku aphezulu okunyibilika kunye nokubilisa.
2. Iimpawu zeMichiza: I-Melamine iyikhompawundi ezinzile akulula ukubola kwiqondo lokushisa. Iyanyibilika emanzini kunye nezinye izinyibilikisi eziphilayo ezifana ne-methanol kunye ne-acetic acid.
Sebenzisa:
1. Kwishishini, i-melamine isoloko isetyenziswa njengento ekrwada ye-resin zokwenziwa, njengefiber ye-acrylic, iiplastiki ze-phenolic, njl. Inobushushu obugqwesileyo kunye nokumelana nemichiza.
2. I-Melamine ingasetyenziswa njengento yokunqanda ilangatye, idayi, ii-pigments kunye nezongezo zephepha.
Indlela:
Ukulungiswa kwe-melamine ngokuqhelekileyo kuqhutyelwa ngokusabela kwe-urea kunye ne-formaldehyde. I-Urea kunye ne-formaldehyde zisabela phantsi kweemeko ze-alkaline ukuvelisa i-melamine kunye namanzi.
Ulwazi ngoKhuseleko:
1. I-Melamine inetyhefu ephantsi kwaye inempembelelo encinci ebantwini nakwimekobume.
3. Xa usebenzisa kwaye ugcina imelamine, kuphephe ukudibana nolusu namehlo, kwaye unxibe iiglavu zokukhusela kunye nezibuko ukuba kuyimfuneko.
4. Ekulahlweni kwenkunkuma, imithetho efanelekileyo kunye nemimiselo kufuneka ithotyelwe ukuphepha ukungcoliseka kwendalo.
