HPMC Hydroxypropyl methyl cellulose, yomwe imadziwikanso kuti hydroxypropyl methyl cellulose ether (HPMC), cellulose hydroxypropyl methyl ether, ndikusankhidwa kwa thonje la thonje loyera kwambiri ngati zopangira, pansi pamikhalidwe yamchere mwapadera komanso kukonzekera.
Hydroxypropyl methyl cellulose HPMC ntchito yomanga, mapadi etere anawonjezera kuchuluka ndi otsika kwambiri, koma akhoza kwambiri kusintha ntchito ya chonyowa matope, ntchito yomanga matope ndi chowonjezera chachikulu. Tsopano, hydroxypropyl methyl cellulose yomwe imagwiritsidwa ntchito mumatope owuma a cellulose ether imakhala makamaka hydroxypropyl methyl cellulose ether (HPMC). Hydroxypropyl methyl cellulose pomanga matope owuma HPMC makamaka imagwira ntchito posungira madzi, kukhuthala, kupititsa patsogolo ntchito yomanga.
1, matope omanga pulasitala
Kusungirako madzi ambiri kungapangitse simenti kukhala ndi madzi okwanira, kuonjezera mphamvu ya mgwirizano, ndipo kungathe kupititsa patsogolo mphamvu zowonongeka ndi kumeta ubweya, kupititsa patsogolo ntchito yomanga, kupititsa patsogolo ntchito.
2, madzi kukana putty
Mu putty HPMC hydroxypropyl methyl cellulose ether makamaka amatenga gawo la kusunga madzi, kulumikiza ndi kudzoza, kupewa zochitika za ming'alu ndi kutaya madzi m'thupi chifukwa cha kutayika kwamadzi mwachangu, ndikuwonjezera kumamatira kwa putty, kuchepetsa chodabwitsa cha kutuluka kwamadzi. yomanga, kotero kuti yomangayo ndi yosalala.
3, utoto wa gypsum mndandanda
Mu gypsum mndandanda wa mankhwala HPMC hydroxypropyl methyl cellulose etha makamaka kusewera madzi posungira, kuonjezera kondomu ndi zotsatira zina, pa nthawi yomweyo ali ndi zina kuchedwa kwenikweni, kuthetsa ntchito yomanga ng'oma akulimbana, mphamvu koyamba si mpaka vuto, akhoza kutalikitsa. nthawi yogwira ntchito.
4, mawonekedwe othandizira
Imagwiritsidwa ntchito makamaka ngati thickener, imatha kupititsa patsogolo mphamvu zamakokedwe ndi kumeta ubweya, kukonza zokutira pamwamba, kumawonjezera kumamatira ndi mphamvu zomangirira.
5, kunja kutchinjiriza matope
HPMC Hydroxypropyl methyl cellulose, mapadi etero mu zinthu kuganizira kugwirizana, kuonjezera mphamvu, kukhala kosavuta kwa matope ❖ kuyanika, kusintha ntchito Mwachangu, pa nthawi yomweyo ndi ofukula otaya kukana, mkulu madzi posungira ntchito akhoza kutalikitsa nthawi ntchito matope, onjezerani shrinkage ndi kukana kutopa kwamafuta, sinthani mawonekedwe apamwamba, onjezerani mphamvu zomangira.
6, chomangira matailosi a ceramic
High madzi posungira sangakhoze Pre-zilowerere kapena chonyowa ceramic matailosi ndi maziko, kwambiri bwino chomangira mphamvu yake, slurry kungakhale yaitali yomanga mkombero, wosakhwima, yunifolomu, yomanga yomanga, ndipo ali kukana zabwino chinyezi.
7, wothandizira kudzaza msoko, wothandizira olumikizana
Kuphatikiza kwa hydroxypropyl methyl cellulose HPMC cellulose ether kumapangitsa kuti ikhale yomatira bwino m'mphepete, kutsika kochepa komanso kukana kuvala kwambiri, kuteteza zida zoyambira ku kuwonongeka kwamakina, kupewa kulowerera kwanyumba yonse.
8, zinthu zodziyimira pawokha
Hydroxypropyl methyl cellulose cellulose etha khola chomangira kuonetsetsa zamadzimadzi zabwino ndi kudziletsa leveling luso, kulamulira madzi kasungidwe kachulukidwe kuti akhoza kulimba mwamsanga, kuchepetsa kusweka ndi kutsika.
9. utoto wa latex
Hydroxypropyl methyl cellulose mu ❖ kuyanika makampani mapadi efa monga filimu-kale, thickening wothandizila, emulsifier ndi stabilizer ntchito, likhale ndi zabwino abrasion kukana, ❖ kuyanika, zomatira, kuwongolera Mkhalidwe wa PH kufunika pamwamba mavuto, ndi organic zosungunulira osakaniza zotsatira. ndiyabwinonso, magwiridwe antchito a Gao Baoshui amapangitsa kuti ikhale ndi maburashi abwino komanso kutuluka.
10. Zoumba za zisa
Muzoumba zatsopano za uchi, billet imapatsidwa lubricity, kusunga madzi ndi kupititsa patsogolo mphamvu.
Zinthu zabwino kwambiri za hydroxypropyl methyl cellulose zimatha kuthetsa vuto la kusunga madzi kutentha kwambiri. M'nyengo yotentha kwambiri, makamaka m'malo otentha ndi owuma komanso kumanga wosanjikiza pang'ono kumbali yadzuwa, HPMC yapamwamba kwambiri ndiyofunikira kuti ipititse patsogolo kusunga madzi kwa slurry. Mkulu khalidwe HPMC, mofanana ndi zabwino kwambiri, methoxy ndi hydroxypropyl magulu pamodzi mapadi maselo unyolo yunifolomu kugawa, akhoza kusintha hydroxyl ndi etere chomangira pa maatomu mpweya ndi madzi mayanjano hydrogen chomangira mphamvu, kupanga madzi ufulu mu madzi ophatikizana, kuti mogwira mtima. kuwongolera kutuluka kwa madzi chifukwa cha kutentha kwanyengo, kuti mukwaniritse kusunga madzi ambiri.
Mkulu khalidwe la hydroxypropyl methyl mapadi akhoza uniformly ndi bwino kumwazikana mu simenti matope ndi pulasitala mankhwala, ndi phukusi onse olimba particles, ndi kupanga wosanjikiza wa kunyowetsa filimu, chinyezi m'munsi kwa nthawi yaitali pang'onopang'ono anamasulidwa, ndi inorganic cementitious zinthu hydration anachita. , kuti awonetsetse mphamvu ya mgwirizano ndi mphamvu yopondereza ya zipangizo. Choncho, mu kutentha kwa chilimwe kumanga, kuti akwaniritse zotsatira za kusunga madzi, malinga ndi chilinganizo kuwonjezera mkulu khalidwe HPMC mankhwala, apo ayi, padzakhala kuyanika mofulumira chifukwa cha kusakwanira hydration, kuchepetsa mphamvu, akulimbana, ng'oma dzenje ndi. kugwa ndi mavuto ena khalidwe, komanso kuwonjezera vuto la ogwira ntchito yomanga. Pamene kutentha kumachepa, kuchuluka kwa HPMC kumatha kuchepetsedwa pang'onopang'ono, ndipo zotsatira zofanana zosungira madzi zimatha kupezeka.
