SCSC - TH ua avea ma mea fou e tete'e i lavalava e gaosia ai laina o hydrocyclones.
O meatotino a Silicon carbide sintered oloa e aofia ai le malosi malosi, malosi maualuga ma maualuga thermostability. Ae ui i lea, o ia ituaiga o oloa e i ai tulaga le lelei, e pei o le le lelei o le malosi, vaivai ma isi. Ina ia mafai ona faʻafetaui i tulaga o galuega ole hydrocyclone, e manaʻomia le faʻaleleia atili. Ua fa'aleleia atili e Zhongpeng lana fa'agasologa, fausia ma fa'alauiloa mai se mea fou e fa'asa'o fa'aofuofu talafeagai mo le afa mamafa tele lea e ta'ua o le SCSC-TH. O se mea fou tioata faʻapipiʻiina e ala i le faʻaopoopoina o elemene elemene i le faagasologa o le sintering silicon carbide ma faʻafefeteina ma tali atu i le vevela maualuga. O ona vaega autu o le kemikolo o le SiC, C, Mo, ma isi. Binary poʻo le multivariate hexagonal faʻapipiʻi fausaga e fausia i le maualuga o le siosiomaga vevela. o le mea lea, o lenei oloa e sili ona maaa, malosi maualuga, lubricating e le tagata lava ia (maualalo feteʻenaʻiga), anti-adhesion, corrosion tetee ma maualuga vevela tetee.
O le tuufaatasiga o vailaʻau ma mea faʻapitoa o loʻo faʻaalia i le laulau 1 ma le laulau 2.
