Kodi Hydroxyethyl cellulose ndi chiyani?

Hydroxyethyl cellulose (HEC) ndi yoyera kapena yopepuka yachikasu, yopanda fungo, yopanda poizoni kapena yolimba, yokonzedwa ndi etherification ya cellulose yamchere ndi ethylene oxide (kapena chlorohydrin).
1.Malangizo
1.1 idawonjezedwa mwachindunji panthawi yopanga

1. Thirani madzi oyera pachidebe chachikulu chokhala ndi chosakaniza chometa ubweya wambiri.

2. Yambani kusonkhezera mosalekeza pa liwiro lotsika ndikusefa pang'onopang'ono hydroxyethyl cellulose mu yankho mofanana.

3. Pitirizani kuyambitsa mpaka tinthu tating'onoting'ono tanyowa.

4. Kenaka yikani antifungal wothandizira, zowonjezera zamchere monga ma pigment, dispersing aids, ammonia madzi.

5. Onetsetsani mpaka cellulose yonse ya hydroxyethyl itasungunuka kwathunthu (kukhuthala kwa yankho kumawonjezeka kwambiri) musanawonjezere zigawo zina mu ndondomeko, ndikupera mpaka mankhwala omalizidwa.

1.2 Kukonzekera ndi chakumwa cha mayi

Njira iyi ndikukonzekeretsa chakumwa cha mayi kuti chisasunthike kwambiri, kenako ndikuwonjezera pa utoto wa latex. Ubwino wa njirayi ndikuti umakhala ndi kusinthasintha kwakukulu ndipo ukhoza kuwonjezeredwa mwachindunji ku utoto womalizidwa, koma uyenera kusungidwa bwino. Masitepewa ndi ofanana ndi Masitepe 1-4 mu Njira 1, kusiyana kwake ndikuti palibe chifukwa chogwedeza mpaka utasungunuka kwathunthu mu njira yothetsera viscous.

2.Parridge ya phenology
Popeza organic zosungunulira ndi osauka zosungunulira kwahydroxyethyl cellulose, zosungunulira organic izi angagwiritsidwe ntchito pokonzekera phala. Zosungunulira zomwe zimagwiritsidwa ntchito kwambiri ndi zinthu zamadzimadzi monga ethylene glycol, propylene glycol ndi mafilimu opangira mafilimu (monga ethylene glycol kapena diethylene glycol butyl acetate) popanga utoto. Madzi a ayezi nawonso samasungunuka bwino, motero madzi a ayezi nthawi zambiri amagwiritsidwa ntchito limodzi ndi zakumwa zamadzimadzi pokonzekera phala. Ma cellulose a hydroxyethyl a phala amatha kuwonjezeredwa mwachindunji ku utoto, ndipo cellulose ya hydroxyethyl yagawidwa ndikutupa mu phala. Akawonjezeredwa ku utoto, amasungunuka nthawi yomweyo ndipo amakhala ngati thickener. Pambuyo powonjezera, pitirizani kuyambitsa mpaka hydroxyethyl cellulose itasungunuka kwathunthu ndi yunifolomu. Nthawi zambiri, phala limapangidwa posakaniza magawo asanu ndi limodzi a organic zosungunulira kapena madzi a ayezi ndi gawo limodzi la hydroxyethyl cellulose. Pambuyo pa mphindi 6-30, cellulose ya hydroxyethyl imapangidwa ndi hydrolyzed ndikutupa mwachiwonekere. M'chilimwe, kutentha kwamadzi kumakhala kokwera kwambiri, kotero sikoyenera kugwiritsa ntchito phala.
3.Munda wa ntchito

Hydroxyethyl mapadi Ntchito zomatira, surfactants, colloidal zoteteza wothandizira, dispersants, etc.
Ili ndi ntchito zosiyanasiyana pa utoto, utoto, ulusi, utoto, kupanga mapepala, zodzoladzola, mankhwala ophera tizilombo, kukonza mchere, zobwezeretsa mafuta, ndi mankhwala.

1. Hydroxyethyl mapadi amagwiritsidwa ntchito monga thickener, zoteteza wothandizila, zomatira, stabilizer ndi zowonjezera pokonza emulsion, odzola, mafuta odzola, oyeretsa diso, suppository ndi piritsi, komanso ntchito monga hydrophilic gel osakaniza ndi mafupa Zida, kukonzekera Kukonzekera kwamtundu wa matrix wokhazikika, komanso kungagwiritsidwe ntchito ngati chokhazikika pazakudya.

2. Hydroxyethyl mapadi Amagwiritsidwa ntchito ngati sizing wothandizila mu mafakitale nsalu, ndi ngati wothandizira wothandiza kwa kugwirizana, thickening, emulsifying, ndi kukhazikika mu zamagetsi ndi kuwala makampani makampani.

3. Amagwiritsidwa ntchito ngati thickener ndi kutaya madzimadzi kutaya reducer kwa madzi pobowola madzimadzi ndi kumaliza madzimadzi, ndi thickening zotsatira zoonekeratu mu brine pobowola madzimadzi. Itha kugwiritsidwanso ntchito ngati chochepetsera kutaya madzi kwa simenti yamafuta bwino. Itha kulumikizidwa ndi ayoni achitsulo a polyvalent kuti apange gel.

4. Hydroxyethyl mapadi mankhwala ntchito ngati dispersant kwa polymerization wa mafuta ofotokoza madzi ofotokoza gel osakaniza fracturing madzimadzi, polystyrene ndi polyvinyl kolorayidi, etc. ndi fracturing. Itha kugwiritsidwanso ntchito ngati emulsion thickener mumakampani opanga utoto, hygrostat mumakampani amagetsi, anticoagulant ya simenti ndi chosungira chinyezi pantchito yomanga. Ceramic industry glazing ndi mankhwala otsukira mano binder. Amagwiritsidwanso ntchito kwambiri posindikiza ndi kudaya, nsalu, kupanga mapepala, mankhwala, ukhondo, chakudya, ndudu, mankhwala ophera tizilombo ndi zozimitsa moto.

5. Monga surfactant, colloidal zoteteza wothandizira, emulsification stabilizer kwa vinilu kolorayidi, vinilu acetate ndi emulsions ena, komanso latex tackifier, dispersant, dispersion stabilizer, etc. Amagwiritsidwa ntchito kwambiri mu zokutira, ulusi, utoto, papermaking, zodzoladzola, mankhwala, mankhwala, mankhwala, mankhwala, , etc. Lilinso ndi ntchito zambiri mu kufufuza mafuta ndi makampani makina.

6. Hydroxyethyl cellulose imakhala ndi ntchito yogwira ntchito, yowonjezera, yoyimitsa, yomangiriza, emulsifying, kupanga mafilimu, kufalitsa, kusunga madzi ndi ntchito zotetezera mu mankhwala olimba ndi amadzimadzi.

7. Amagwiritsidwa ntchito ngati dispersant polymeric pogwiritsira ntchito mafuta a petroleum madzi opangidwa ndi gel fracturing fluid, polyvinyl chloride ndi polystyrene. Angagwiritsidwenso ntchito ngati emulsion thickener mu makampani utoto, simenti anticoagulant ndi chinyezi posungira wothandizila ntchito yomanga, wothandizila glazing ndi zomatira otsukira mano mu makampani ceramic. Amagwiritsidwanso ntchito kwambiri m'mafakitale monga kusindikiza ndi utoto, nsalu, kupanga mapepala, mankhwala, ukhondo, chakudya, ndudu ndi mankhwala ophera tizilombo.
