CAS 9032-42-2 HEMC pazokonda zomanga
1. HEMC hydroxyethyl methyl cellulose imapangidwa kuchokera ku thonje la thonje loyera kwambiri.Pambuyo pa chithandizo cha alkali ndi etherification yapadera imakhala HEMC.Lilibe mafuta a nyama ndi zinthu zina zogwira ntchito.
2. Maonekedwe a HEMC ndi tinthu toyera kapena ufa, wopanda fungo komanso wopanda kukoma.Ndi hygroscopic ndipo sangathe kusungunuka m'madzi otentha, acetone.ethanol ndi toluene.Pambuyo potupa m'madzi ozizira kukhala yankho la colloidal, kusungunuka sikukhudzidwa ndi mtengo wa PH.Ndizofanana ndi methyl cellulose, koma ndi kuwonjezeka kwa magulu a hydroxyethyl, zimakhala zolekerera kwambiri, zimasungunuka mosavuta m'madzi ndipo zimakhala ndi kutentha kwakukulu kwa condensation.
3. Hemc imagwira ntchito yokulitsa, kusunga madzi, komwe kuli koyenera kwambiri popangira zida zopangira utoto, inki ndi kubowola mafuta.
4. Chowonjezera chabwino cha zipangizo za ufa.Amagwiritsidwa ntchito ngati gelling agent, madzi osungira masenti ndi gypsum.
Zowonjezera za HEMC zomanga 1

1. HEMC imagwira ntchito yokulitsa, kusunga madzi, komwe kuli koyenera kwambiri kupenta pogwiritsa ntchito madzi, zomangira, inki ndi kubowola mafuta.
2. Chowonjezera chabwino cha zipangizo za ufa.Amagwiritsidwa ntchito ngati gelling wothandizira, madzi posungira simenti, gypsum.
3. Amagwiritsidwa ntchito ngati chowonjezera cha phala la mano, zodzoladzola ndi zotsukira.
➢Nthawi yayitali yotseguka
➢Kukana kwambiri kuterera
➢Kusunga madzi kwambiri
➢Kukwanira kokwanira kumamatira mphamvu
Sungani phukusi loyambirira pamalo owuma komanso ozizira.Pambuyo potulutsa katundu, ziyenera kusindikizidwa mwamphamvu mwamsanga kuti chinyezi chisalowe;
Phukusi: 25kg / thumba, multilayer pepala pulasitiki gulu thumba, lalikulu pansi vavu doko, mkati polyethylene filimu thumba.
Chonde mugwiritseni ntchito mkati mwa miyezi 6, ndipo mugwiritseni ntchito mwamsanga pansi pa kutentha kwakukulu ndi chinyezi, kuti musawonjeze mwayi wa caking.
