Chiyambi cha Hydroxypropyl Methyl Cellulose
Hydroxypropyl methylcellulose, yomwe imadziwikanso kuti hypromellose ndi HPMC cellulose hydroxypropyl methyl ether, imapangidwa ndi cellulose ya thonje yoyera kwambiri ngati zopangira, zomwe zimapangidwira mwapadera pansi pamikhalidwe yamchere.HPMC ndi ufa woyera, wosakoma, wopanda fungo, wopanda poizoni, wosasinthika m'thupi la munthu ndipo umachokera m'thupi.Mankhwalawa amasungunuka m'madzi, koma osasungunuka m'madzi otentha.The amadzimadzi yothetsera ndi colorless manla viscous mankhwala.HPMC ali thickening kwambiri, emulsifying, filimu kupanga, dispersing, zoteteza colloid, chinyezi posungira, adhesion, asidi ndi alkali kukana, enzyme kukana ndi katundu wina, ndipo chimagwiritsidwa ntchito yomanga, zokutira, mankhwala, chakudya, nsalu, mafuta minda, zodzoladzola, kutsuka Agents, zoumba, inki ndi mankhwala polymerization njira.
1. Kashiamu wochepa wa calcium wotuwa ndi chiŵerengero chosayenera cha CaO ndi Ca(OH)2 mu grey calcium zidzachititsa kuti ufa uwonongeke.Ngati ili ndi chochita ndi HPMC, ndiye ngati kusungirako madzi kwa HPMC kuli koyipa, kungayambitsenso kutaya ufa.Kodi ufa wa ufa wa putty ufa umagwirizana ndi hydroxypropyl methylcellulose?Kutayika kwa ufa wa putty powder makamaka kumagwirizana ndi khalidwe la phulusa la calcium, ndipo silikugwirizana kwenikweni ndi HPMC.
2. Ntchito yofunika kwambiri ya hydroxypropyl methylcellulose ndi kusunga madzi, kutsatiridwa ndi thickening.Mu ufa wa putty, malinga ngati kusungirako madzi kuli bwino ndipo kukhuthala kuli kochepa (70,000-80,000), ndizothekanso.Zoonadi, kukwezeka kwa viscosity kumapangitsa kuti madzi azikhala bwino.Pamene mamasukidwe akayendedwe kuposa 100,000, mamasukidwe akayendedwe adzakhudza kasungidwe madzi.Osatinso zambiri.
Kodi kukhuthala kwa hydroxypropyl methylcellulose (HPMC) ndi chiyani?
Ufa wa putty nthawi zambiri umakhala 100,000 yuan, ndipo zofunikira pamatope ndizokwera, ndipo 150,000 yuan ndizofunikira kuti zigwiritsidwe ntchito mosavuta.
3. Kodi zida zazikulu za hydroxypropyl methylcellulose ndi ziti?Zida zazikulu za hydroxypropyl methylcellulose (HPMC): thonje woyengedwa, methyl chloride, propylene oxide, ndi zina zopangira, caustic koloko, asidi, Toluene, isopropanol, etc.
4. Kodi fungo la hydroxypropyl methylcellulose ndi chiyani?Hydroxypropyl methylcellulose yopangidwa ndi njira yosungunulira imagwiritsa ntchito toluene ndi isopropanol monga zosungunulira.Ngati kusamba sikuli bwino, padzakhala fungo lotsalira .
5. Hydroxypropyl methylcellulose: Yomwe imakhala ndi hydroxypropyl yambiri imakhala yabwinoko pakusunga madzi.Yemwe ali ndi kukhuthala kwakukulu amakhala ndi madzi osungira bwino, (osati mwamtheradi), ndipo yomwe ili ndi kukhuthala kwakukulu imagwiritsidwa ntchito bwino mumatope a simenti.Zizindikiro zazikulu zaukadaulo ndi chiyani?Hydroxypropyl zili ndi mamasukidwe akayendedwe, owerenga ambiri nkhawa zizindikiro ziwirizi.
Kodi chodabwitsa cha efflorescence mumatope chikugwirizana ndi hydroxypropyl methylcellulose?
Kale, kasitomala ananena kuti mankhwala anali efflorescence, ndipo iye anali kupopera mbewu mankhwalawa.Shotcrete: Ntchito yayikulu ndikuphimba kumbuyo, roughen, ndikuwonjezera kumamatira pakati pa khoma ndi zinthu zapamtunda.Gwiritsani ntchito pang'ono, ingopoperani pang'ono pakhoma.Nachi chithunzi cha zochitika za efflorescence zomwe kasitomala adanditumizira: Chithunzi Zomwe ndimachita koyamba ndikuti sizomwe zimayambitsa hydroxypropyl methylcellulose, chifukwa hydroxypropyl methylcellulose sagwirizana ndi chilichonse mumfuti.Ndipo chodabwitsa cha efflorescence ndi: konkire wamba ndi silicate, ikakumana ndi mpweya kapena chinyezi pakhoma, ion silicate imakumana ndi hydrolysis reaction, ndipo hydroxide yopangidwa imaphatikizana ndi ayoni zitsulo kupanga hydroxide yokhala ndi kusungunuka kochepa (mankhwala a alkaline) , kutentha kukakwera, nthunzi wamadzi umasanduka nthunzi, ndipo hydroxide imatuluka kuchokera kukhoma.Ndi nthunzi wapang'onopang'ono wa madzi, hydroxide imatenthedwa pamwamba pa simenti ya konkire, yomwe imachulukana pakapita nthawi, kupanga zokongoletsera zoyambirira Pamene utoto kapena utoto umakwezedwa ndipo sukugwirizananso ndi khoma, kuyera, kupukuta, ndi kupukuta. peeling idzachitika.Njirayi imatchedwa "pan-alkali".Chifukwa chake si ubiquinol yoyambitsidwa ndi hydroxypropyl methylcellulose
Makasitomala anatchulanso chodabwitsa: grout sprayed iye anapanga adzakhala poto-zamchere chodabwitsa pa khoma konkire, koma sikuwoneka pa khoma njerwa anawotcha, zomwe zimasonyeza kuti pakachitsulo mu simenti ntchito pa khoma konkire Salts (mwamphamvu zamchere). salt) ndi okwera kwambiri.Efflorescence chifukwa cha evaporation ya madzi omwe amagwiritsidwa ntchito mu spray grouting.Komabe, palibe silicate pakhoma la njerwa zowotchedwa ndipo palibe efflorescence yomwe idzachitika.Kotero chodabwitsa cha efflorescence sichikugwirizana ndi kupopera mbewu mankhwalawa.
Yankho:
1. Simenti ya silicate ya simenti yoyambira imachepetsedwa.
2. Gwiritsani ntchito anti-alkali back coating agent, yankho limalowa mwala kuti litseke capillary, kotero kuti madzi, Ca (OH) 2, mchere ndi zinthu zina sangathe kulowa, ndikudula njira ya pan-alkaline phenomenon.
3. Pewani kulowa kwa madzi, ndipo musawaze madzi ambiri musanamangidwe.
Chithandizo cha pan-alkaline phenomenon:
Mwala efflorescence kuyeretsa wothandizira pamsika angagwiritsidwe ntchito.Choyeretsera ichi ndi madzi otuluka opanda mtundu opangidwa ndi zinthu zosungunulira zosakhala ndi ma ionic.Zimakhala ndi zotsatira zina pakuyeretsa kwa miyala ina yachilengedwe.Koma musanagwiritse ntchito, onetsetsani kuti mwapanga chipika chaching'ono choyesera kuti muyese zotsatira zake ndikusankha kuti mugwiritse ntchito.
Kugwiritsa Ntchito Ma Cellulose M'makampani Omanga
1. Tondo la simenti: Kupititsa patsogolo kufalikira kwa mchenga wa simenti, kusintha kwambiri pulasitiki ndi kusunga madzi mumatope, kumathandizira kupewa ming'alu, komanso kulimbitsa mphamvu ya simenti.
2. Simenti ya matailosi: sinthani pulasitiki ndi kusunga madzi kwa matailosi oponderezedwa, kukulitsa kumamatira kwa matailosi, ndikuletsa kuchoko.
3. Kuphimba kwa zinthu zotsutsa monga asibesitosi: monga choyimitsa, madzi owonjezera amadzimadzi, komanso kumapangitsanso mphamvu yomangirira ku gawo lapansi.
4. Gypsum coagulation slurry: kupititsa patsogolo kusungirako madzi ndi kusinthika, ndikuwongolera kumamatira ku gawo lapansi.

8. Zophimba: Monga pulasitiki yopangira zokutira latex, imatha kukonza magwiridwe antchito ndi madzimadzi a zokutira ndi ufa wa putty.
9. Kupopera utoto: Kumathandiza kupewa kumira kwa simenti kapena zipangizo zopopera mbewu za latex ndi zodzaza ndi kukonzanso madzi ndi kutsitsi.
10. Zinthu zachiwiri za simenti ndi gypsum: zomwe zimagwiritsidwa ntchito ngati chopangira chopangira simenti-asibesitosi ndi zinthu zina zamtundu wa hydraulic kuti zipititse patsogolo madzi ndi kupeza zinthu zopangidwa ndi yunifolomu.
11. Fiber khoma: Chifukwa cha anti-enzyme ndi anti-bacterial effect, imakhala yothandiza ngati chomangira makoma a mchenga.
12. Zina: Itha kugwiritsidwa ntchito ngati mpweya kuwira posungira wothandizira (PC Baibulo) kwa woonda dongo mchenga matope ndi matope hayidiroliki woyendetsa.
Mapulogalamu mumakampani opanga mankhwala
1. Polymerization wa vinilu kolorayidi ndi vinylidene: Monga kuyimitsidwa stabilizer ndi dispersant pa polymerization, angagwiritsidwe ntchito pamodzi ndi vinilu mowa (PVA) hydroxypropyl mapadi (HPC) kulamulira tinthu mawonekedwe ndi tinthu kugawa.
2. Zomatira: Monga zomatira pamapepala, zitha kugwiritsidwa ntchito limodzi ndi utoto wa vinyl acetate latex m'malo mwa wowuma.
3. Mankhwala ophera tizirombo: Kuphatikizira ku mankhwala ophera tizirombo ndi herbicides, kumatha kukulitsa mphamvu yomatira popopera mbewu mankhwalawa.
4. Latex: Emulsion stabilizer ya asphalt latex, thickener for styrene-butadiene rabara (SBR) latex.
5. Binder: monga chomangira chopangira mapensulo ndi makrayoni.
Ntchito mu makampani zodzoladzola
1. Shampoo: Limbikitsani kukhuthala kwa shampu, zotsukira, ndi zoyeretsera komanso kukhazikika kwa thovu.
2. Mankhwala otsukira m'mano: Sinthani kutsekemera kwa mankhwala otsukira mkamwa.
Ntchito mu makampani opanga mankhwala
1. Encapsulation: The encapsulation agent amapangidwa kukhala organic solvent solution kapena amadzimadzi njira yoyendetsera mankhwala, makamaka kwa kupopera encapsulation wa granules okonzeka.
2. Wothandizira pang'onopang'ono: 2-3 magalamu patsiku, 1-2G nthawi iliyonse, zotsatira zake zidzawoneka m'masiku 4-5.
3. Madontho a diso: Popeza kuti mphamvu ya osmotic ya methylcellulose aqueous solution ndi yofanana ndi ya misozi, imakhala yochepa kwambiri m'maso, choncho imawonjezeredwa ku madontho a maso monga mafuta okhudzana ndi lens ya diso.
4. Odzola: monga m'munsi zinthu za odzola-ngati kunja mankhwala kapena mafuta.
5. Kuviika mankhwala: monga thickener, madzi posungira wothandizira
