Kugwiritsa Ntchito Hydroxypropyl Methyl Cellulose mu Zipangizo Zomangira

1. Kuchuluka kwa hydroxypropyl methyl cellulose
Hydroxypropyl methylcellulose (HPMC)ndi ether ya cellulose yosakhala ionic yopangidwa kuchokera ku cellulose yachilengedwe ya polymer kudzera mu njira zingapo zopangira mankhwala. Hydroxypropyl methylcellulose (HPMC) ndi ufa woyera wopanda fungo, wopanda kukoma, komanso wopanda poizoni womwe ungasungunuke m'madzi ozizira kuti upange yankho lowoneka bwino la viscous. Ili ndi mphamvu ya kukhuthala, kumatira, kufalikira, emulsification, kupanga filimu, kuyimitsidwa, kulowetsedwa, gelation, ntchito pamwamba, kusunga chinyezi ndi colloid yoteteza.

2. Kodi cholinga chachikulu cha Hydroxypropyl methylcellulose (HPMC) n'chiyani?

HPMC imagwiritsidwa ntchito kwambiri pa zipangizo zomangira, zokutira, ma resini opangidwa, zinthu zadothi, mankhwala, chakudya, nsalu, ulimi, zodzoladzola, fodya ndi mafakitale ena. HPMC ikhoza kugawidwa m'magulu omanga, chakudya ndi zamankhwala malinga ndi cholinga chake. Pakadali pano, zinthu zambiri zapakhomo zimakhala zamagulu omanga. Mumagulu omanga, ufa wa putty umagwiritsidwa ntchito kwambiri, pafupifupi 90% imagwiritsidwa ntchito pa ufa wa putty, ndipo wotsalawo amagwiritsidwa ntchito pa simenti ndi guluu.

1.） Mtondo wopangira miyala ndi matope opaka pulasitala

Kusunga madzi ambiri kungathe kunyowetsa simenti mokwanira. Kuonjezera mphamvu ya chigwirizano. Nthawi yomweyo, kungathandize kulimbitsa mphamvu ya kukoka ndi kumeta. Kungathandize kwambiri pa ntchito yomanga ndikuwonjezera mphamvu yogwirira ntchito.

2. ） Putty yosalowa madzi

Ntchito yaikulu ya cellulose ether mu putty ndi kusunga madzi, kumatira ndi mafuta, kuti madzi asatayike kwambiri zomwe zimayambitsa ming'alu kapena kuchotsa ufa, komanso nthawi yomweyo kuwonjezera kumatira kwa putty, kuchepetsa kutsika kwa madzi panthawi yomanga, ndikupangitsa kuti kapangidwe kake kakhale kosalala. Mosavuta.

3. ） Wothandizira mawonekedwe

Imagwiritsidwa ntchito makamaka ngati chokhuthala, imatha kulimbitsa mphamvu yokoka ndi kumeta, kukonza zokutira pamwamba, ndikuwonjezera mphamvu yomatira ndi yolumikizana.

4. ） Chophimba chakunja cha kutentha

Cellulose ether imagwira ntchito yofunika kwambiri pakulumikizana ndi kuwonjezera mphamvu mu chinthuchi, kupangitsa kuti matopewo azioneka mosavuta, kukonza bwino ntchito, komanso kukhala ndi mphamvu yoletsa kupachikidwa. Kugwira ntchito bwino kwa madzi kumatha kuwonjezera nthawi yogwira ntchito ya matopewo ndikuwonjezera kukana kwa kufupika ndi kukana kwa ming'alu, kukonza mawonekedwe a pamwamba, ndikuwonjezera mphamvu ya matopewo.

5） Tailosi yomatira

Kusunga madzi ambiri kumathandiza kuti matailosi ndi zinthu zina zisamanyowe kapena kunyowetsa, zomwe zingathandize kwambiri kuti matailosi ndi zinthu zina zigwirizane bwino. Madzi amatha kupangidwa nthawi yayitali, ndi ofewa, ofanana, osavuta kupanga, komanso ali ndi mphamvu zabwino zoletsa kutsetsereka.

6.） Wothandizira kutsekereza

Kuwonjezera kwa cellulose ether kumapangitsa kuti ikhale yolimba bwino m'mphepete, yocheperako komanso yolimba kwambiri, imateteza maziko ku kuwonongeka kwa makina, komanso imapewa zotsatira zoyipa za kulowa kwa madzi m'nyumba yonse.

7.) Zinthu zodziyimira payokha

Kukhuthala kokhazikika kwa ether ya cellulose kumatsimikizira kusinthasintha kwabwino komanso kuthekera kodziyimira pawokha, komanso kumayang'anira kuchuluka kwa madzi kuti azitha kulimba mwachangu ndikuchepetsa ming'alu ndi kuchepa.
