Engtin nge order ka siam theih ang?

Order information kimchang tak dawng turin kan sales representative tu hnenah pawh zawhna min thawn mai thei a, a chipchiar dan tur kan sawifiah ang.Step 1: DissolutionAdd an appropriate amount of deionized water to technical grade oxalic acid for dissolution. A hmasa berin oxalic acid powder chu beaker-ah dah la, chutah chuan zawi zawiin deionized water dah la, glass rod hmangin a hmin vek thlengin hrual rawh. Oxalic acid leh tui ratio hi a hmin vek theih nan control tur a ni tih hre reng ang che.
Step 2: FiltrationOxalic acid solution hmin chu funnel leh filter paper hmangin filter la, bawlhhlawh leh thil hmin theih loh te chu paih chhuak rawh.
Step 3: CrystallizationOxalic acid solution filtered chu electric hot plate hmangin partial crystallization a awm thlengin dah la. Tichuan, a lumna chu titawp la, solution chu room temperature thlenga lum turin dah la, crystallization chhunzawm zel turin. Hetiang method hian oxalic acid thianghlimna a tichak a, crystallization laiin crystal lattice atanga bawlhhlawh paih chhuah a nih avangin.
Step 4: Silfai Crystallized oxalic acid chu ethanol hmangin silfai ang che. Crystals te chu ethanol ah dah la, zawi zawiin stir la, chutah chuan filter rawh. He step hian crystal surface-a bawlhhlawh awmsa awmte chu a paih chhuak a, thianghlimna a ti sang zual hle.
Step 5: DryingOxalic acid crystal silfai tawhte chu—anhydrous silica gel hmangin emaw, oven-ah emaw—Dry-in, a hnim hring chu paih chhuakin, high-purity oxalic acid i hmu ang.
A chunga kan sawi tak hian oxalic acid chu tha takin a tithianghlim a, thianghlimna sang tak a siam chhuak thin. Practical operation-ah chuan purification efficiency a awm theih nan step tinah condition leh parameter control-naah ngaihven tur a ni. High-purity oxalic acid hi experiment leh production process-ah high-grade acid mamawhnaah hman theih a ni a, hei hian experimental result dik tak leh product quality stability a tichiang a ni.
