Sodium Hexametaphosphate
Sodium Hexametaphosphate
Kev siv:Siv ua emulsifier, dispersant, tshem tawm cov hlau ions, kev ntxhib los mos txhim kho tus neeg sawv cev.Kev ua cov nqaij, cov khoom ua dej hauv dej, tus neeg saib xyuas dej, ua cov dej haus thiab lwm yam hauv cov khoom noj.
Ntim:Nws tau ntim nrog lub hnab polyethylene ua txheej txheej sab hauv, thiab lub hnab yas sib xyaw ua ke raws li txheej txheej.Qhov hnyav ntawm txhua lub hnab yog 25kg.
Cia thiab thauj:Nws yuav tsum tau muab khaws cia rau hauv qhov chaw qhuav thiab qhov cua, khaws cia kom deb ntawm tshav kub thiab noo noo thaum lub sijhawm thauj mus los, tshem tawm nrog kev saib xyuas kom tsis txhob muaj kev puas tsuaj.Tsis tas li ntawd, nws yuav tsum tau muab cais tawm ntawm cov tshuaj lom.
