Ntchito yofunika ya madzi sungunukahydroxypropyl methyl cellulose HPMCmu matope n'kofunika mbali zitatu, mmodzi ndi wabwino kwambiri madzi posungira luso luso, awiri ndi kuwonongeka kwa mamasukidwe akayendedwe ndi compressibility matope, atatu ndi mogwirizana ndi simenti. Osauka madzi posungira matope mu ndondomeko yonse ya zoyendera n'zosavuta kulekanitsa madzi outflow, kufalikira padziko porous zakuthupi, madzi ambiri n'zosavuta kuti atengeke digest, kutulutsa kusintha mbali ya matope, matope pansi kuwonongeka kwa zonse zachilendo coagulation ndi tiziduswa tating'ono ting'ono ya zipangizo pakati kugwirizana ndi kuchepetsa compressive mphamvu ya zomangamanga khoma. Kusungidwa kwa madzi kwa matope kumafotokozedwa ndi stratification.
The wamkulu mamasukidwe akayendedwe ahydroxypropyl methyl celluloseHPMC, kusungirako bwino madzi, kumapangitsanso kukhuthala kwa ma polima amadzimadzi. Kutalika ndi mawonekedwe a unyolo wa maselo kumadaliranso kuchuluka kwa maselo a polima (kutentha kwa kusintha kwa galasi). Chiwerengero cha magulu ogwira ntchito chimakhudzanso mtundu wa viscosity.
Hydroxypropyl methyl cellulose HPMC mwiniwake posungira madzi ntchito kuchokera ku hydroxypropyl methyl cellulose kusungunuka kwake komanso kugwiritsa ntchito madzi. Ndizodziwika bwino kuti mapadi sasungunuke m'madzi chifukwa cha mawonekedwe ake okwera kwambiri a crystalline, ngakhale unyolo wa mamolekyulu a ulusiwo uli ndi magulu ambiri a OH okhala ndi hydrated.
Ma covalent bond apamwamba kwambiri ndi mphamvu za van der Waals pakati pa mamolekyu sangalipidwe ndi mphamvu ya hydration ya magulu a methyl okha. Choncho, akhoza kusungunuka m'madzi okha. Pamene mamolekyu m'malo anayambitsa, osati m'malo mamolekyulu kuwononga unyolo wa haidrojeni, komanso covalent zomangira mu unyolo wa haidrojeni amawonongedwa ndi m'malo mamolekyulu wedges mu maunyolo oyandikana. M'malo mokulirapo, m'pamenenso kuchulukana kwa mamolekyu. Chofunikira kwambiri pakuphwanya ma covalent bond. Pamene fiber lattice ikukulirakulira, njira yamadzimadzi imalowa ndipo hydroxypropyl methyl cellulose imasungunuka m'madzi, zomwe zimapangitsa kuti pakhale njira yowoneka bwino kwambiri yamadzi.
Kutentha kozungulira kumakwera, hydration ya polima imakhala yochepa ndipo madzi amatulutsidwa pakati pa unyolo. Madzi okwanira akachotsedwa, mamolekyuwa amasonkhana pang’onopang’ono, n’kupanga minyewa ya mbali zitatu imene imatha kutambasulidwa. Kukhuthala, mlingo, kukula kwa tinthu ndi kutentha kwa hydroxypropyl methyl cellulose ndizomwe zimawononga kasungidwe kamadzi mumatope.
Hydroxypropyl methyl cellulose viscosity imagawidwa mu: mamasukidwe 100,000, mamasukidwe 150,000, mamasukidwe 200,000.
Momwe mungasankhire hydroxypropyl methyl cellulose?
100,000 viscosity hydroxypropyl methyl cellulose angagwiritsidwe ntchito ngati mkati khoma putty ufa. Binder ya matailosi. Caulking wothandizira. Mtondo wa konkriti womangika. Kulimba kwakukulu kopanda shrinkage grouting.
Inorganic insulation insulation matope mafotokozedwe ndi apamwamba, kukhuthala kwa 150,000 hydroxypropyl methyl cellulose kapena 200,000 hydroxypropyl methyl cellulose. Ngati kusankha zipatso zatsopano mamasukidwe akayendedwe ndi 100 zikwi, kutulutsa otaya kupachika chodabwitsa mosavuta.
Udindo waukulu wa methyl cellulose ndikusunga madzi, ndikutsatiridwa ndi makulidwe. Kutopa ndi ufa wa ana mkati mwa khoma, ngati uli ndi madzi osungunuka bwino komanso otsika kukhuthala (70000-80000), angagwiritsebe ntchito. Pamene mamasukidwe akayendedwe kuposa 100,000, mamasukidwe akayendedwe si zovulaza kuti madzi posungira. Popanga ndi kupanga mkati mwa khoma putty ufa, palibe chifukwa chosankha 200,000 mamasukidwe akayendedwe. Chifukwa kukhuthala kwake ndi kwakukulu, kumakhala kovuta kukanda ndi kukanda kwambiri.
Hydroxypropyl methyl cellulose imagwiritsa ntchito viscosity ya 100,000.
1. Engineering polojekiti konkire matope mtanda putty matope.
Kusungunuka kwamadzi kwapamwamba kungapangitse konkire kuti ikhale yokwanira, mphamvu zomatira zimapitirizabe kuwonjezeka. Mofananamo, mphamvu ya compressive ndi laser kudula compressive mphamvu zitha kukhala bwino, ndiyeno kuwongolera zomwe zikuyembekezeka pakumanga nyumba, kuwongolera bwino.
2. Inner khoma putty ufa chinyezi kukana.
Mu putty, moisturizing, kugwirizana, kondomu n'kofunika kwambiri, kuteteza kuchuluka kwa madzi chifukwa cha ming'alu ndi youma zinthu bwino kugwirizana kwa mkati khoma putty ufa, kuchepetsa otaya ikulendewera chodabwitsa mu zomangamanga, zomangamanga zomangamanga wachibale yosalala.
3. Pulasita wa Paris brushing mndandanda mankhwala.
Mu pulasitala wa mankhwala Paris mndandanda, ali ndi zotsatira zazikulu za kusunga madzi, thickening ndi kunyowetsa. Momwemonso, imakhala ndi zotsatira zoyambira, zomwe zimatha kuwonjezera nthawi yomanga ndikuthana ndi zovuta zosweka komanso mphamvu zopondereza zoyambira pantchito yomanga.
4. Putty wosalowa madzi.
Monga ntchito yofunika kwambiri ya demulsifier, imatha kupititsa patsogolo mphamvu zamakokedwe komanso mphamvu zopondereza za laser, kukonza zokutira pamwamba, kuwongolera kumamatira ndikumangirira mphamvu zolimba.
5. Ceramic matailosi zomatira.
Matailosi apansi osungunuka m'madzi ndi zoyambira zamafakitale siziyenera kunyowa kapena kunyowa pasadakhale, zomwe zimathandizira kwambiri kulimbitsa mphamvu yolumikizirana. Nthawi yomanga ndi yayitali, yosakhwima komanso yofananira, kupulumutsa nthawi ndi khama pomanga. Kuphatikiza apo, ilinso ndi lubricity yapamwamba kwambiri.
6. Caulking wothandizira. Trench sealant.
HPMC CHIKWANGWANI ndi mkulu khalidwe adhesion, shrinkage otsika ndi mkulu kuvala kukana, kukonza zopangira zopangira chiwonongeko cha zipangizo mafakitale, kupewa kulowerera ntchito zonse zomangamanga.
7. Dc plain materials.
Kuthekera kolumikizana kosalala kumapangitsa kuti konkriti yoyenda bwino komanso yodziyimira payokha, isinthe kuchuluka kwa chinyezi kuti ikhale yolimba komanso kuchepetsa kusweka ndi kutseka.
8. Industrial utoto khoma latex utoto.
M'makampani opanga zokutira ndi zopangira, methylpropyl methyl cellulose ingagwiritsidwe ntchito ngati chopangira filimu, demulsifier, demulsifier ndi zomatira, kuti filimuyo ikhale yabwino kukana, kuyika bwino kwa zokutira, kumamatira komanso kugwedezeka kwa pH ndikofunikira. kukonza. Zotsatira zomwe zikuyembekezeredwa zimakhalanso zabwino zikasakanizidwa ndi zosungunulira za organic. Ili ndi kusungirako chinyezi chambiri komanso magwiridwe antchito apamwamba kwambiri a penti.
Hydroxypropyl methyl cellulose 1500000 viscosity.
Pakati pa 100,000 mamasukidwe akayendedwe ndi 200,000 mamasukidwe akayendedwe, 150,000 mamasukidwe akayendedwe pafupi 100,000 mamasukidwe akayendedwe.
Hydroxypropyl methyl cellulose 200,000 ntchito.
Mu zomangira, makamaka ntchito inorganic insulating wosanjikiza matope, chinthu chofunika kwambiri ndi kusintha cohesivity, kuonjezera zotsatira za kumakoka mphamvu, kupanga matope konkire mosavuta kumata, kusintha dzuwa. Kuphatikiza apo, ili ndi anti-vertical liquidity effect. Kuchita bwino konyowa kumatha kutalikitsa nthawi yothamanga ya matope a konkriti, kupititsa patsogolo kukana kwa fracture ndi kukhazikika, kupititsa patsogolo mawonekedwe apamwamba, kumamatira.
(1) Kusungidwa kwa madzi kwa methyl cellulose kumadalira kuchuluka kwake, kukhuthala, kukongola kwa tinthu ndi kuchuluka kwa kusungunuka. Nthawi zambiri, kuchuluka kwake kumakhala kokulirapo, fineness ndi yaying'ono, mamasukidwe ake ndi akulu, kuchuluka kwa kusungitsa madzi ndikwambiri, komwe kuchuluka kwake kumakhudza kwambiri kuchuluka kwa kusungirako madzi, kukhuthala ndi kusungitsa madzi sikutsika. kuposa ubale, mlingo kuvunda makamaka zimadalira pamwamba kusinthidwa digirii ndi tinthu fineness wa mapadi particles. Methyl cellulose ndi hydroxypropyl methyl cellulose m'ma cellulose ether angapo pamwambapa ali ndi kuchuluka kwa kusunga madzi.
