mankhwala

Mawu ofanana mu Chingerezi

kuyeretsa utoto

mankhwala katundu

Chilinganizo cha mankhwala: CH2(OH)SO2Na Kulemera kwa molekyulu: 118.10 CAS: 149-44-0EinECs: 205-739-4 Malo osungunuka: 64 mpaka 68 ℃ Malo otentha: 446.4 ℃ Pointi yowala: 223.8 ℃

Chiyambi cha malonda ndi mawonekedwe ake

Condole block, yomwe imadziwikanso kuti diao white powder, kuti formalin kuphatikizapo sodium bisulfite rereduction, dzina la mankhwala formaldehyde sodium bisulfite, mankhwala opangira CH2 (OH) SO2Na, chipika choyera kapena ufa wa crystalline, palibe fungo kapena fungo la leek pang'ono;Kusungunuka m'madzi, kusungunuka pang'ono mu mowa.Ndi khola kutentha firiji, ndipo ali amphamvu reducibility ndi bleaching kwenikweni pa kutentha kwambiri.Pankhani ya kuwonongeka kwa asidi, hydrogen sulfide imatulutsidwa, yokhazikika pamene PH> 3, yokhazikika ku alkali.Nthawi zambiri amagwiritsidwa ntchito m'mafakitale osindikizira ndi opaka utoto ngati chotsitsa ndi kuchepetsa kupanga utoto wa indigo, kuchepetsa utoto ndi zina zotero.Koma sayenera kugwiritsidwa ntchito ngati chakudya bleaching zowonjezera, mosamalitsa oletsedwa kulowa.

ntchito

Ndi bleaching wothandizira ntchito mafakitale chifukwa cha mphamvu reducibility pa kutentha kwambiri.M'makampani osindikizira ndi opaka utoto amagwiritsidwa ntchito ngati wothandizira kuchotsa ndi kuchepetsa, kupanga utoto wa indigo;Amagwiritsidwanso ntchito ngati mphira makampani styrene butadiene mphira polymerization activator;Photosensitive zithunzi zipangizo gawo auxiliaries;Bleaching wothandizira tsiku ndi tsiku ndi makampani mankhwala.

phukusi ndi transport

B. Izi zitha kugwiritsidwa ntchito, 25KG, m'migolo.
C. Sungani chosindikizidwa mu malo ozizira, owuma ndi mpweya wokwanira m'nyumba.Zotengera ziyenera kutsekedwa mwamphamvu mukatha kugwiritsa ntchito chilichonse musanagwiritse ntchito.
D. Mankhwalawa ayenera kusindikizidwa bwino panthawi yoyendetsa kuti ateteze chinyezi, alkali wamphamvu ndi asidi, mvula ndi zonyansa zina kuti zisasakanike.
