Namuhla, i-Huafu Chemicals izokwabelana nawe ngenqubo yokukhiqiza ye-melamine yokubumba inhlanganisela.
Okokuqala, ake sifunde isimiso sokusabela.
I-Melamine tableware powderkuvame ukwakhiwa ngokulawula isilinganiso se-molar ye-formaldehyde ku-triamine cishe ngo-1: 2, bese sishisa kufika ku-80 C. Ngemva kokusabela, umkhiqizo uyi-resin encibilikayo ye-prepolymer.Umkhiqizo oyimpushana uzokwakhiwa ube umkhiqizo ngokusabela okuxhumanisa ngokusebenzisa izinga lokushisa eliphezulu nokucindezela okukhulu.
Umfanekiso 1-1 Inqubo yokukhiqiza yezimboni ye-melamine yokubumba inhlanganisela
Manje, sizonikeza isingeniso esifushane senqubo yokukhiqiza.
1.Ukusabela:isinyathelo esibaluleke kakhulu enqubweni yokukhiqiza.Imishini yokusabela ngokuvamile isebenzisa i-reactor yensimbi engagqwali futhi isikhathi sokusabela kufanele sibe phakathi kwemizuzu engama-90-120.
2. Ukuxova:I-resin etholakala ngokuxova ngokuvamile ixutshwa ne-pulp emshinini wokuxova cishe imizuzu engama-60 kuya kwangu-80.
3.Ukomisa:Umphumela wokomisa ukukhipha umswakama futhi ama-granules azomiswa esomisini emahoreni angu-2.5 kuya kwangu-3.
4. Ukugaywa kwebhola:ngokuvamile eyenziwa ku-miller yebhola.Ama-granules agaywe kahle ngokusebenzisa i-shear namandla okuthinta phakathi kwamabhola e-ceramic.
5.Ukuhlola:Kusekhona ezinye izinto ezimahhadlahhadla noma ukungcola okungahlungwa ngesikrini esidlidlizayo ukuze kuqinisekiswe ukuthi ukucoleka komkhiqizo kufinyelela ezingeni elihlanganisiwe.
6.Ukupakisha:isinyathelo sokugcina sokukhiqiza.Kunezingqimba ezimbili zezikhwama zokupakisha;isikhwama sangaphandle siyisikhwama sephepha, kanti isikhwama sangaphakathi siyifilimu yepulasitiki, ifaka umswakama futhi ingangenisi uthuli.
Amakhemikhali e-Huafuikhethekile ekukhiqizeniinhlanganisela ye-melamineiminyaka engaphezu kwengu-20.Noma yiziphi izimboni ze-tableware ezinentshisekelo ku-Huafu melamine powder, sicela ukhululeke ukuxhumana nathi.
