I-Melamine Molding Compound Yebhokisi Lokudla Lefriji
Izinto ezingavuthiwe zokwenza izitsha zihlanzekilei-melamine powder. I-Melamine Molding compoundyenziwe nge-melamine ne-formaldehyde futhi ayinabo ubuthi.Kuyinto thermosetting resin.Ngakho-ke, i-melamine yokubumba i-compound ingabunjwa ibe yizitsha ekushiseni okuphezulu.Lena yinhlanganisela ye-thermosetting enikezwa ngemibala ehlukahlukene.Le nhlanganisela inezici ezivelele zama-athikili abunjiwe, lapho ukumelana namakhemikhali nokushisa kuhle kakhulu.Ngaphezu kwalokho, ubulukhuni, inhlanzeko kanye nokuqina kwendawo nakho kuhle kakhulu.Itholakala ngempushana ye-melamine emsulwa namafomu ayimbudumbudu, kanye nemibala eyenziwe ngokwezifiso yempushana ye-melamine edingwa amakhasimende.
Indawo Engokoqobo:
Inhlanganisela yokubumba i-melamine ngendlela eyimpuphu isekelwe ku-melamine-formaldehydeama-resin aqiniswe ngokuqiniswa kwama-cellulose ekilasi eliphezulu futhi aphinde alungiswa ngamanani amancane ezithasiselo zenjongo ekhethekile, ombala, izilawuli zokwelapha kanye nezinto zokugcoba.
Izinzuzo:
1. Umbala omuhle, umbala ozinzile nokucwebezela, izinhlobonhlobo zemibala, ozikhethela.
2. I-fluidity elula kanye ne-fluidity enzima ukuhlangabezana nezidingo zokubumba.
3. Izakhiwo ezinhle zemishini, ukumelana nomthelela, isiphetho esingeyona intekenteke futhi esihle.
4. Ukubambezeleka kwelangabi eliphezulu nokushisa okuhle nokumelana namanzi.
5. Ayinabuthi, ayinaphunga, ihlangabezana nezidingo zokuvikelwa kwemvelo kwaseYurophu.
Izicelo:
1. I-tableware: njengamapuleti, izinkomishi, amasoso, i-ladle, izinkezo, izitsha namasoso, njll.
2. Imikhiqizo yokuzijabulisa: njengama-dominoes, amadayisi, i-mahjong, i-chess, njll.
3. Izidingo zansuku zonke: njengethreyi lomlotha, izinkinobho, umgqomo kadoti, isivalo sesihlalo sendlu yangasese.
Isitoreji:
Isitoreji ku-25 centigrade sinikeza ukuzinza izinyanga eziyisi-6.Gwema umswakama, ukungcola, umonakalo wokupakisha, nezinga lokushisa eliphezulu okuthinta ukuhamba kwezinto kanye nekhono layo lokukhunta.
