Kalasi Yomangamanga (HPMC) Hydroxypropyl methyl cellulose
Mitondo yosakanizidwa ya simenti yakhala gawo lofunikira kwambiri pamakampani opanga matope ku Global ndipo amatenga gawo lofunika kwambiri chifukwa cholimbikitsa msika komanso thandizo ladziko lonse.Pakukula kwa matope, cellulose ether ndi wolimbikitsa kwambiri.
Mtondo wamba ndiwofunika kwambiri pazachuma pomwe simenti ndi yaying'ono, koma zofunikira pakugwiritsa ntchito kwake ndi kupopera mbewu mankhwalawa ndi makina akadali apamwamba, kotero kuyika mchenga ndi zowonjezera ndizofunikira.Kuphatikiza apo, kugwiritsa ntchito kwamakina kudzakhala chizolowezi chokhazikika cha matope osakaniza okonzeka, ether ya cellulose imapangitsa kugwiritsa ntchito makina.
Zogulitsa Zamalonda
Wonjezerani kufunikira kwa madzi.
Kusungidwa kwamadzi kwambiri, kutalikitsa nthawi yogwiritsira ntchito zinthu, kukonza magwiridwe antchito, kupewa zochitika zakutukuta, ndikuthandizira kukonza mphamvu zamakina azinthuzo.
Kupititsa patsogolo ntchito, kupereka mafuta ndi mawonekedwe ofanana, kuti pamwamba pa zinthuzo zikhale zosavuta kupukuta, motero kumapangitsa kuti ntchito yomanga ikhale yabwino, ndikuwongolera kukana kuphulika kwa putty.
Limbikitsani homogeneity, ndikuwongolera kukana koyenda molunjika.
HPMC kwa zomatira matailosi
Ma tiles a ceramic amakhala ndi magwiridwe antchito apamwamba komanso magwiridwe antchito abwino kwambiri akamayikidwa pamagawo osiyanasiyana.Kukana kwa skid ndi nthawi yabwino yotsegulira ndiye chinsinsi cha zomatira bwino.
HPMC kwa khoma putty
HPMC ndi non-ionic cellulose ether yopangidwa kuchokera ku ulusi wa thonje wachilengedwe pansi pakupanga kwamankhwala.Ndi odorless, zoipa ndi sanali poizoni ufa woyera, akhoza kusungunuka m'madzi abwinobwino kupanga mandala viscous njira ndi katundu wa thickening, kumanga, dispersing, emulsifying, filimu ❖ kuyanika, suspending, kuyamwa, gelling, posungira madzi ndi colloid chitetezo.
Ma cellulose ethers amapereka zinthu zabwino zotsatirazi kumatope:
一Kutha konyowetsa kwa gawo lapansi
一 Kutha kwapamwamba posungira madzi
一 ntchito yabwino yopopera mbewu ndi kupopera
一 Kupititsa patsogolo mphamvu ya simenti pomanga mphamvu
Mafotokozedwe Akatundu
1) Maonekedwe: HPMC ndi nonionic mapadi efa, woyera imvi-woyera ufa kapena granule, odorless ndi flavorless, sungunuka m'madzi ozizira, glacial acetic acid, Mowa, methanol ndi propylene glycol, sungunuka pang'ono mu acetone malinga ndi mlingo wa m'malo, pafupifupi osasungunuka m'madzi otentha, ethylene glycol ndi toluene.HPMC imasungunuka mu osakaniza 10% methanol ndi 90% methylene kolorayidi kupanga colloidal njira.
2) Yankho la HPMC lili ndi zochitika zapamtunda, zowonekera kwambiri, komanso magwiridwe antchito okhazikika.Akatenthedwa pa kutentha kwina, yankho limakhala lamitambo kapena limapanga gel osakaniza.Komabe, yankho limawonekeranso pambuyo pozizira.Mitundu yosiyanasiyana ya HPMC ili ndi kutentha kosiyana kwa gelation.Kusungunuka kumasiyanasiyana ndi mamasukidwe akayendedwe.Kutsika kwa viscosity, kusungunuka kwapamwamba komwe kumakhala nako.Mitundu yosiyanasiyana ya HPMC ndi yosiyana muzinthu zina ndipo kusungunuka kwawo m'madzi sikukhudzidwa ndi pH.
3) Kukula kwapang'onopang'ono: 100% kuchuluka kwa ma mesh 80.
4) Kachulukidwe kowoneka: 0.25-0.70 g/mL (nthawi zambiri pafupifupi 0.5 g/mL), kachulukidwe kake 1.26-1.31mL.
5) Kusintha kwamtundu kutentha: 190-200 ° C;Kutentha kwa carbonation: 280-300 ° C.
6) Kupanikizika kwapamtunda: 42-56 dyn / masentimita (2% yankho lamadzi).
7) Zomwe zili pamwamba pa methoxy mu HPMC, kutentha kwapansi kwa gelation, ndi kusungunuka kwapamwamba m'madzi ndi pamwamba.
8) HPMC ali ndi makhalidwe ena, mwachitsanzo, thickening katundu, pH bata, posungira madzi, kwambiri mafilimu kupanga katundu, bwino kumwazikana ndi adhesion luso.
