01 .Hydroxyethyl cellulose
Monga si ionic surfactant, hydroxyethyl cellulose sikuti imangokhala ndi ntchito zoyimitsa, kukhuthala, kubalalitsa, kuyandama, kulumikiza, kupanga filimu, kusunga madzi komanso kupereka colloid yoteteza, komanso ili ndi zinthu zotsatirazi:
1. HEC imasungunuka m'madzi otentha kapena ozizira, ndipo sichimawotcha kutentha kwambiri kapena kutentha, kotero kuti imakhala ndi mitundu yambiri ya solubility ndi viscosity, ndi gelation yopanda kutentha;
2. Poyerekeza ndi methyl cellulose yodziwika bwino ndi hydroxypropyl methyl cellulose, mphamvu yobalalika ya HEC ndiyoipa kwambiri, koma colloid yoteteza imakhala ndi mphamvu zolimba kwambiri.
3. Mphamvu yosungira madzi imakhala yowirikiza kawiri kuposa ya methyl cellulose, ndipo imakhala ndi malamulo oyendetsera bwino.
Kusamala mukamagwiritsa ntchito:
Popeza kuti hydroxyethyl cellulose yopangidwa pamwamba ndi ufa kapena cellulose olimba, n'zosavuta kugwira ndi kusungunuka m'madzi malinga ngati zinthu zotsatirazi zikudziwika.
1. Isanayambe komanso itatha kuwonjezera hydroxyethyl cellulose, iyenera kugwedezeka mosalekeza mpaka yankho likuwonekera bwino komanso lomveka bwino.
2. Iyenera kusefedwa mu mbiya yosakaniza pang'onopang'ono. Osawonjezera mwachindunji cellulose ya hydroxyethyl yomwe idapangidwa kukhala zotupa kapena mipira mu mbiya yosanganikirana yochulukirapo kapena mwachindunji.
3. Kutentha kwa madzi ndi pH ya madzi kumakhala ndi chiyanjano chachikulu ndi kusungunuka kwa cellulose ya hydroxyethyl, choncho chisamaliro chapadera chiyenera kuperekedwa kwa izo.
4. Osawonjezerapo zinthu zamchere kusakaniza musanathehydroxyethyl celluloseufa umatenthedwa ndi madzi. Kukweza mtengo wa PH mutatha kutentha ndikothandiza pakusungunuka.
Kugwiritsa ntchito HEC:
1. Nthawi zambiri amagwiritsidwa ntchito ngati thickening wothandizira, wotetezera, zomatira, stabilizer ndi zowonjezera pokonzekera emulsion, gel osakaniza, mafuta odzola, odzola maso, suppository ndi piritsi, amagwiritsidwanso ntchito ngati gel osakaniza a hydrophilic, zida za mafupa, kukonzekera kwa mafupa okonzekera kumasulidwa, komanso kugwiritsidwa ntchito ngati chakudya.
2. Imagwiritsidwa ntchito ngati sizing agent mumakampani opanga nsalu, kulumikizana, kukhuthala, emulsifying, stabilizing ndi zina zothandizira pazinthu zamagetsi ndi zamagetsi.
3. Amagwiritsidwa ntchito ngati thickener ndi filtrate reducer kwa madzi pobowola madzimadzi ndi kumaliza madzimadzi, ndi zoonekeratu thickening zotsatira mu mchere pobowola madzimadzi. Itha kugwiritsidwanso ntchito ngati chida chowongolera kutaya kwamadzimadzi kwa simenti yamafuta bwino. Itha kulumikizidwa ndi ayoni achitsulo a polyvalent kupanga ma gels.
5. Izi zimagwiritsidwa ntchito ngati dispersant kwa madzi opangidwa ndi gel osakaniza fracturing madzi, polystyrene ndi polyvinyl kolorayidi mu mafuta fracturing kupanga. Itha kugwiritsidwanso ntchito ngati emulsion thickener m'makampani opaka utoto, chinyezi tcheru resistor mumakampani amagetsi, simenti coagulation inhibitor ndi wosungira chinyezi pantchito yomanga. Zomatira zowuma ndi zotsukira mano zamakampani a ceramic. Amagwiritsidwanso ntchito kwambiri posindikiza ndi kudaya, nsalu, kupanga mapepala, mankhwala, ukhondo, chakudya, ndudu, mankhwala ophera tizilombo ndi zozimitsa moto.
02.Hydroxypropyl Methyl Cellulose
1. Kupaka mafakitale: Monga thickener, dispersant ndi stabilizer mu makampani ❖ kuyanika, izo zimagwirizana bwino m'madzi kapena organic solvents. monga chochotsera utoto.
2. Kupanga Ceramic: kumagwiritsidwa ntchito kwambiri ngati chomangira popanga zinthu za ceramic.
3. Zina: Izi zimagwiritsidwanso ntchito kwambiri pazikopa, makampani opanga mapepala, kusunga zipatso ndi masamba ndi mafakitale a nsalu, ndi zina zotero.
4. Kusindikiza kwa inki: monga thickener, dispersant ndi stabilizer mu makampani inki, izo zimagwirizana bwino m'madzi kapena organic solvents.
5. Pulasitiki: ntchito ngati akamaumba kumasula wothandizira, softener, lubricant, etc.
6. Polyvinyl kolorayidi: Amagwiritsidwa ntchito ngati dispersant popanga polyvinyl kolorayidi, ndipo ndi wothandizira wamkulu pokonzekera PVC ndi kuyimitsidwa polymerization.
7. Makampani omangamanga: Monga chosungira madzi ndikubwezeretsanso matope a simenti, matope amakhala ndi pumpability. Amagwiritsidwa ntchito ngati chomangira popaka pulasitala, gypsum, putty powder kapena zinthu zina zomangira kuti azitha kufalikira ndikutalikitsa nthawi yogwira ntchito. Amagwiritsidwa ntchito ngati phala la matailosi a ceramic, marble, zokongoletsera zapulasitiki, monga chowonjezera cha phala, komanso amatha kuchepetsa kuchuluka kwa simenti. Kusungidwa kwa madzi kwa hydroxypropyl methylcelluloseMtengo wa HPMCzimatha kuletsa slurry kuti zisaphwanyike chifukwa chowumitsa mwachangu mukatha kugwiritsa ntchito, ndikuwonjezera mphamvu mukaumitsa.
8. Makampani opanga mankhwala: zida zokutira; filimu zipangizo; kuwongolera-kuwongolera zida za polima pokonzekera kumasulidwa kosalekeza; stabilizers; oyimitsa wothandizira; zomangira piritsi; tackifiers.
Chilengedwe:
1. Maonekedwe: ufa woyera kapena woyera.
2. Kukula kwa tinthu ting'onoting'ono; 100 mauna pass rate ndi wamkulu kuposa 98.5%; 80 mesh pass rate ndi 100%. Kukula kwa tinthu tapadera ndi 40 ~ 60 mauna.
3. Kutentha kwa carbonization: 280-300 ℃
4. Kuwoneka kowoneka bwino: 0.25-0.70g / cm (kawirikawiri pafupifupi 0.5g / cm), mphamvu yokoka yeniyeni 1.26-1.31.
5. Kutentha kwa kutentha: 190-200 ℃
6. Kuthamanga kwapamwamba: 2% yothetsera madzi ndi 42-56dyn / cm.
7. Kusungunuka: kusungunuka m'madzi ndi zosungunulira zina, monga gawo loyenera la ethanol / madzi, propanol / madzi, ndi zina zotero. Kuwonekera kwapamwamba komanso magwiridwe antchito okhazikika. Zosiyanasiyana zazinthu zimakhala ndi kutentha kosiyanasiyana kwa gel osakaniza, komanso kusintha kwa kusungunuka ndi kukhuthala. Kutsika mamasukidwe akayendedwe, m'pamenenso solubility kwambiri. Mafotokozedwe osiyanasiyana a HPMC ali ndi katundu wosiyana. Kutha kwa HPMC m'madzi sikukhudzidwa ndi mtengo wa pH.
8. Ndi kuchepa kwa gulu la methoxy, mfundo ya gel imawonjezeka, kusungunuka kwa madzi kumachepa, ndipo ntchito ya pamwamba ya HPMC imachepa.
9. Mtengo wa HPMCalinso ndi makhalidwe a thickening mphamvu, kukana mchere, otsika phulusa ufa, pH kukhazikika, kusunga madzi, dimensional bata, kwambiri mafilimu kupanga katundu, ndi osiyanasiyana enzyme kukana, dispersibility ndi cohesiveness.
