Iphepha lokucoca i-Great Wall libandakanya amabakala afanelekileyo ukuhluzwa okurhabaxa ngokubanzi, ukuhluzwa okuhle, kunye nokugcinwa kobukhulu obuchaziweyo be-particle ngexesha lokucaciswa kolwelo olwahlukeneyo.Sikwanikezela ngamabakala asetyenziswa njengeseptum ukubamba izixhobo zokucoca kwipleyiti kunye nesakhelo sokucofa isihluzo okanye ezinye izilungiso zokuhluza, ukususa amanqanaba asezantsi eenxalenye, kunye nezinye izicelo ezininzi.
Okufana noku: ukuveliswa kotywala, isiselo esithambileyo, kunye neziselo zejusi yeziqhamo, ukulungiswa kokutya kwee-syrups, i-oyile yokupheka, kunye nokunciphisa, ukugqiba isinyithi kunye nezinye iinkqubo zeekhemikhali, ukulungiswa kunye nokwahlulwa kweoli ye-petroleum kunye ne-wax.
Nceda ujonge kwisikhokelo sesicelo ngolwazi olongezelelweyo.
•Umphezulu owenziwe ngokulinganayo onefibre ye-cellulose pre-coat kwindawo enkulu, esebenzayo ngaphezulu.
•Indawo eyongeziweyo yomphezulu enesantya sokuqukuqela esiphezulu kunezihluzo eziqhelekileyo.
• Amazinga aphezulu okuhamba angagcinwa ngelixa ukucoca ngokufanelekileyo, ngoko ke ukuhluzwa kwe-viscosity ephezulu okanye i-particle ephezulu yoxinaniso lwe-fluid inokwenziwa.
•Ukomelezwa okumanzi.

Asebenza Njani Amaphepha Okucoca?
Amaphepha okucoca ngokwenene zizihluzo ezinzulu.Iiparamitha ezahlukeneyo zinefuthe ekusebenzeni kwazo: Ukugcinwa kwesuntshu kumatshini, ukufunxwa, i-pH, iimpawu zomphezulu, ubukhulu kunye nokomelela kwephepha lokucoca kunye nokumila, ukuxinana kunye nobungakanani bamasuntswana ekufuneka agcinwe.I-precipitates efakwe kwisihlungi yenze "i-cake layer", ethi - kuxhomekeke kubuninzi bayo - ichaphazela kakhulu inkqubela phambili yokucoca kwaye ichaphazele ngokugqithiseleyo amandla okugcina.Ngesi sizathu, kubalulekile ukukhetha iphepha lokucoca elichanekileyo ukuqinisekisa ukuhluzwa okusebenzayo.Olu khetho lukwaxhomekeke kwindlela yokucoca eza kusetyenziswa, phakathi kwezinye izinto.Ukongezelela, ubungakanani kunye neempawu ze-medium ukuba zihluzwe, ubukhulu be-particulate solids ukuba isuswe kunye neqondo elifunekayo lokucacisa zonke zigqibe ekwenzeni ukhetho olufanelekileyo.
I-Great Wall inika ingqwalasela ekhethekileyo ekulawuleni umgangatho oqhubekayo;ukongeza, ukujonga rhoqo kunye nohlalutyo oluchanekileyo lwemathiriyeli ekrwada kunye nemveliso nganye egqityiweyoqinisekisa umgangatho ophezulu rhoqo kunye nokufana kwemveliso.
