1. Kuchuluka kwa hydroxypropyl methyl cellulose
Hydroxypropyl methylcellulose (HPMC)ndi non-ionic cellulose ether yopangidwa kuchokera ku cellulose yachilengedwe ya polima kudzera mumndandanda wamankhwala. Hydroxypropyl methylcellulose (HPMC) ndi ufa woyera wopanda fungo, wosakoma, wopanda poizoni womwe ukhoza kusungunuka m'madzi ozizira kuti upange njira yowonekera yowonekera. Lili ndi katundu wa thickening, adhesion, kubalalitsidwa, emulsification, filimu mapangidwe, kuyimitsidwa, adsorption, gelation, pamwamba ntchito, kusunga chinyezi ndi colloid zoteteza.
2. Cholinga chachikulu cha Hydroxypropyl methylcellulose (HPMC) ndi chiyani?
HPMC chimagwiritsidwa ntchito zomangamanga, zokutira, utomoni kupanga, zoumba, mankhwala, chakudya, nsalu, ulimi, zodzoladzola, fodya ndi mafakitale ena. HPMC akhoza kugawidwa mu kalasi yomanga, kalasi chakudya ndi kalasi zachipatala malinga ndi cholinga chake. Pakali pano, zinthu zambiri zapakhomo ndi za kalasi yomanga. Pomanga kalasi, ufa wa putty umagwiritsidwa ntchito mochuluka, pafupifupi 90% umagwiritsidwa ntchito ngati putty ufa, ndipo enawo amagwiritsidwa ntchito ngati matope a simenti ndi guluu.
3. Kugwiritsa ntchitoHydroxypropyl Methyl Cellulosemu Zida Zomangira
1. ）Dongo lomanga ndi pulasitala
Kusunga madzi kwambiri kumatha kutsitsa simenti mokwanira. Kuonjezera kwambiri mphamvu ya mgwirizano. Panthawi imodzimodziyo, imatha kupititsa patsogolo mphamvu zolimbitsa thupi komanso kumeta ubweya. Kuwongolera kwambiri ntchito yomanga ndikuwonjezera magwiridwe antchito.
2. ）Putty wosamva madzi
Ntchito yaikulu ya cellulose ether mu putty ndi kusunga madzi, kumamatira ndi kudzoza, kupewa kutaya madzi ochulukirapo kumayambitsa ming'alu kapena kuchotsedwa kwa ufa, ndipo nthawi yomweyo kuonjezera kumamatira kwa putty, kuchepetsa zochitika zowonongeka panthawi yomanga, ndikupangitsa kuti zomangamanga zikhale zosavuta. Zopanda khama.
3. ）Chiyankhulo chothandizira
Imagwiritsidwa ntchito makamaka ngati thickener, imatha kupititsa patsogolo kulimba kwamphamvu komanso kumeta ubweya, kukonza zokutira pamwamba, ndikuwonjezera kumamatira ndi mphamvu zomangirira.
4. ）Mtondo wotsekera kunja kwa kutentha
Ma cellulose ether amagwira ntchito yofunika kwambiri pakulumikizana ndikuwonjezera mphamvu pazinthu izi, kupangitsa kuti matope azikhala osavuta kuvala, kuwongolera magwiridwe antchito, komanso kukhala ndi luso loletsa kupachika. Kuchita kwapamwamba kosungirako madzi kumatha kukulitsa nthawi yogwira ntchito yamatope ndikuwongolera anti-shrinkage ndi Crack resistance, kupititsa patsogolo mawonekedwe apamwamba, ndikuwonjezera mphamvu zomangirira.
5） Zomatira matailosi
Kusungidwa kwamadzi kwapamwamba kumathetsa kufunika konyowetsa kale kapena kunyowetsa matailosi ndi magawo, zomwe zimatha kupititsa patsogolo mphamvu zomangira. The slurry imatha kupangidwa kwa nthawi yayitali, yofewa, yofananira, yosavuta kupanga, komanso imakhala ndi zinthu zabwino zotsutsa.
6. ）Caulking agent
Kuphatikiza kwa cellulose ether kumapangitsa kuti azikhala ndi zomatira zabwino m'mphepete, kuchepa kwapang'onopang'ono komanso kukana kwambiri kwa abrasion, kumateteza zinthu zoyambira ku kuwonongeka kwamakina, ndikupewa kuwonongeka kwa madzi panyumba yonseyo.
7. ）Zinthu zodziyimira pawokha
Kukhuthala kokhazikika kwa cellulose ether kumatsimikizira kusungunuka kwamadzi komanso kudziwongolera, ndikuwongolera kuchuluka kwa madzi osungirako kuti athe kukhazikika mwachangu ndikuchepetsa kusweka ndi kuchepa.
