Kufotokozera:
Glycerol ndi mowa wa trihydric wopanda mtundu, wokhuthala, wokhuthala, komanso wokoma. Umatchedwanso glycerin kapena glycerine, ndipo mawu akuti glycerol amakondedwa ngati mankhwala enieni ndipo mawu akuti glycerin(e) amagwiritsidwa ntchito makamaka pamene mankhwalawo akugwiritsidwa ntchito m'magawo osiyanasiyana.

Kagwiritsidwe Ntchito
Kapangidwe ka Glycerol kamathandiza kwambiri pa ntchito zambiri. Magulu atatu a hydroxyl mu glycerol amalola hydrogen kulumikizana kwakukulu komwe kumapatsa glycerol mawonekedwe ake apadera a syrup viscous komanso mawonekedwe ake a hygroscopic. Pafupifupi 40% ya kagwiritsidwe ntchito ka glycerol ndi zinthu zosamalira thupi monga zodzoladzola, sopo, shampu, mafuta odzola, zotsukira pakamwa, ndi mano otsukira mano. Kapangidwe ka hygroscopic ka Glycerol kamachititsa kuti ikhale mafuta abwino kwambiri pakhungu. 25% ina ya kapangidwe ka glycerol pachaka imagwiritsidwa ntchito popanga chakudya. Mu makampani azakudya, glycerol imagwiritsidwa ntchito ngati chonyowetsa, ngati chosungunulira utoto wa chakudya ndi madzi, kuti shuga asapangike mu maswiti ndi ma icing, ngati chosungira, komanso ngati chotsekemera. Pafupifupi 10% ya kagwiritsidwe ntchito ka glycerol imapita ku kukonza fodya, komwe imapopera masamba a fodya asanadulidwe kuti ikhale chonyowetsa. Glycerol ili ndi phindu lowonjezera lopatsa kukoma kokoma kwa fodya wotafuna. 25% yotsala ya glycerol imagwiritsidwa ntchito m'mafakitale osiyanasiyana. Imagwiritsidwa ntchito mu mankhwala a chifuwa ndi elixir. M'mafakitale, glycerol imapezeka mu mafuta odzola, mapulasitiki, zomatira, zoletsa kuzizira, ma resin, ndi ma thovu oteteza. Poyamba imagwiritsidwa ntchito pafupifupi mu mawonekedwe ake a nitrate ngati chophulika (onani Nitroglycerin), yomwe masiku ano imawerengera pafupifupi 3% ya ntchito zake.
Glycerol ndi mankhwala ophera fungo omwe amagwiritsidwa ntchito mu zodzoladzola. Amamangirira madzi ndipo amatha kukoka ndikuyamwa madzi kuchokera mumlengalenga, motero amathandiza khungu kusunga chinyezi. glycerin yafufuzidwa kwambiri chifukwa cha mphamvu zake zonyowetsa madzi. Kutengera ndi deta yomwe ilipo, glycerin yadziwika kuti ndi mankhwala abwino onyowetsa khungu. Gawo lina la ntchito yake limanenedwa kuti limapangitsa kuti ma enzyme azichita zinthu pakhungu, zomwe zimapangitsa kuti corneocyte ichotsedwe. glycerin imathandizanso kufalitsa mafuta ndi mafuta odzola. Ndi madzi omveka bwino, okhala ndi madzi opangidwa mwa kuphatikiza madzi ndi mafuta omwe nthawi zambiri amachokera ku mafuta a masamba. Ngakhale kuti glycerin sinawonetsedwe kuti imayambitsa ziwengo, ikhoza kukhala yowopsa komanso yokwiyitsa nembanemba ya mucous ikagwiritsidwa ntchito mu njira zosakanikirana.
Glycerol imagwiritsidwa ntchito pokonza zitsanzo komanso kupanga gel ya polyacrylamide gel electrophoresis. Glycerol (5-10%) imawonjezera kuchuluka kwa chitsanzo kotero kuti chitsanzocho chizikhala pansi pa chitsime cha gel. Glycerol imagwiritsidwanso ntchito pothandiza kupanga ma gradient gels komanso ngati protein stabilizer ndi storage buffer component.
Monga chosungunulira, chosungunulira, chopukutira pulasitiki, chosungunulira, chotsekemera, popanga nitroglycerol (dynamite), zodzoladzola, sopo wamadzimadzi, zakumwa zoledzeretsa, zosakaniza, inki zosindikizira ndi kukopera, mafuta, zomatira zotanuka, simenti ya lead oxide; kusunga nsalu kukhala zofewa; kusunga kusindikiza pa thonje; posindikizira ma roller, ma hectograph; kuteteza chisanu ku mawilo amoto; monga choletsa kuzizira m'magalimoto, mita ya gasi ndi ma hydraulic jacks, m'madzimadzi onyowa. Mu fermentation nutrients popanga maantibayotiki. Mankhwala othandizira (humectant; solvent, vehicle). Leffingwell ndi Lesser (op. cit.) amapereka ntchito zosiyanasiyana 1583.
Kulongedza ndi Kutumiza
250KG/Drum kapena malinga ndi zomwe makasitomala amafuna.
Ndi katundu wamba ndipo amatha kutumizidwa kudzera m'nyanja ndi mlengalenga
Sungani ndi kusunga
Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
