Kugwiritsa Ntchito Kwambiri kwa Hydroxypropyl Methyl Cellulose

Hydroxypropyl methyl cellulose, yotchedwa (HPMC): hydroxypropyl methyl cellulose (HPMC) ndi ufa woyera wopanda fungo, wosakoma, wopanda poizoni, pali mitundu iwiri ya pompopompo komanso yopanda nthawi, nthawi yomweyo, ikakumana ndi madzi ozizira, imathamanga mwachangu. amabalalitsa ndikuzimiririka m'madzi. Panthawi imeneyi, madzi alibe mamasukidwe akayendedwe. Pambuyo pa mphindi 2, kukhuthala kwamadzimadzi kumawonjezeka, ndikupanga mawonekedwe a viscous colloid. Mtundu wosakhala wanthawi yomweyo: Itha kugwiritsidwa ntchito pazinthu za ufa wouma monga ufa wa putty ndi matope a simenti. Sichingagwiritsidwe ntchito mu guluu wamadzimadzi ndi utoto, ndipo padzakhala clumping.

A. Thupi ndi mankhwala katundu

1. Maonekedwe: ufa woyera kapena wosayera, wopanda fungo komanso wosakoma.

2. Kukula kwa tinthu ting'onoting'ono: kuchuluka kwa ma mesh 100 ndikokulirapo kuposa 98.5%; chiphaso cha 80 mauna ndi chachikulu kuposa 100%.

3. Kutentha kwa carbonization: 280-300 ° C.

4. Kuwoneka kowoneka bwino: 0.25-0.70g / (kawirikawiri pafupifupi 0.5g /), mphamvu yokoka yeniyeni 1.26-1.31.

5. Kutentha kwamtundu: 190-200 ° C.

6. Kuthamanga kwapamwamba: 20% yothetsera madzi ndi 42-56dyn / cm.

7. Kusungunuka: Kusungunuka m'madzi ndi zina zosungunulira zamoyo, monga ethanol / madzi, propanol / madzi, dichloroethane, ndi zina zotero. Njira yothetsera madzi imakhala ndi zochitika zapamtunda, zowonekera kwambiri komanso zokhazikika. Zamgulu ndi specifications osiyana ndi kutentha osiyana gelation, umene ndi matenthedwe gelation katundu wa HPMC. Solubility imasiyanasiyana ndi mamasukidwe akayendedwe, kutsika kwa mamasukidwe akayendedwe, kusungunuka kwakukulu, kusiyanasiyana kosiyanasiyana kwa HPMC kumakhala ndi kusiyana kwina kwa magwiridwe antchito, ndipo kusungunuka kwa HPMC m'madzi sikukhudzidwa ndi mtengo wa pH.

8. Ndi kuchepa kwa methoxy content, gel point ya HPMC imawonjezeka, kusungunuka kwa madzi kumachepa, ndipo ntchito yapamtunda imachepanso.

9. HPMC ilinso ndi makhalidwe a thickening luso, kukhetsa mchere, otsika phulusa okhutira, pH kukhazikika, kusunga madzi, dimensional bata, kwambiri mafilimu kupanga katundu, osiyanasiyana enzyme kukana, dispersibility ndi cohesiveness.

Ntchito ya Hydroxypropyl methylcellulose:

• Ikhoza kulimbitsa matope osakaniza atsopano kuti akhale ndi viscosity yonyowa ndikuletsa tsankho. (kukula)

• Kusungirako madzi ndi khalidwe lofunika kwambiri, lomwe limathandiza kusunga madzi aulere mumatope, kuti zinthu za simenti zikhale ndi nthawi yochuluka yothira madzi pambuyo pa matope. (kusungira madzi)

• Lili ndi katundu wolowetsa mpweya, womwe ukhoza kuyambitsa yunifolomu ndi mpweya wabwino kuti ukhale wogwira ntchito bwino wa matope.

B. Ubwino wa hydroxypropyl methylcellulose pantchito yomanga

magwiridwe antchito:

1. Ndikosavuta kusakaniza ndi ufa wouma wouma.

2. Iwo ali ndi makhalidwe a madzi ozizira kumwazikana.

3. Imitsani tinthu tating'onoting'ono bwino, ndikupangitsa kuti kusakaniza kukhala kosavuta komanso kofanana.

kusakaniza:

1. Fomula yowuma yokhala ndi cellulose ether imatha kusakanikirana mosavuta ndi madzi.

2. Pezani mwachangu kusinthasintha komwe mukufuna.

3. Kusungunuka kwa cellulose ether kumathamanga komanso popanda zotupa.

zomangamanga:

1. Limbikitsani lubricity ndi pulasitiki kuti mupititse patsogolo makina ndikupangitsa kupanga zinthu kukhala kosavuta komanso mwachangu.

2. Limbikitsani mawonekedwe osungira madzi ndikutalikitsa nthawi yogwira ntchito.

3. Imathandiza kupewa kuyenda molunjika kwa matope, matope ndi matailosi. Wonjezerani nthawi yozizirira ndikuwongolera magwiridwe antchito.

4. Limbikitsani mphamvu yomangirira ya zomatira za matailosi.

5. Limbikitsani kuchepa kwa anti-crack ndi mphamvu yotsutsa-kung'amba ya matope ndi bolodi lophatikizana.

6. Kupititsa patsogolo mpweya mumatope, kuchepetsa kwambiri kuthekera kwa ming'alu.

7. Ikhoza kupititsa patsogolo kukana kosunthika kwa zomatira za matailosi.

8. Gwiritsani ntchito ndi Max wowuma ether, zotsatira zake zimakhala bwino!

C. Kugwiritsa ntchito hydroxypropyl methylcellulose pantchito yomanga

Putty wosamva madzi pamakoma amkati ndi akunja:

1. Kusungirako bwino kwa madzi, komwe kungapangitse nthawi yomanga ndikuwongolera ntchito. Kupaka mafuta ambiri kumapangitsa kuti kumanga kukhale kosavuta komanso kosavuta. Amapereka mawonekedwe abwino komanso owoneka bwino pamapangidwe osalala a putty.

2. Kukhuthala kwakukulu, nthawi zambiri 100,000 mpaka 150,000 timitengo, kumapangitsa kuti putty ikhale yomatira pakhoma.

3. Sinthani kukana kwa shrinkage ndi kukana ming'alu, sinthani mawonekedwe apamwamba.

Mlingo wolozera: 0.3 ~ 0.4% pamakoma amkati; 0.4 ~ 0.5% kwa makoma akunja;

Mtondo wotsekereza khoma wakunja

1. Limbikitsani kumamatira ndi khoma pamwamba, ndikuwonjezera kusungirako madzi, kuti mphamvu ya matope ikhale yabwino.

2. Sinthani mafuta ndi pulasitiki kuti ntchito yomanga ikhale yabwino. Itha kugwiritsidwa ntchito limodzi ndi Shenglu brand starch ether kulimbitsa matope, omwe ndi osavuta kupanga, amapulumutsa nthawi komanso kuwongolera mtengo.

3. Kuwongolera kulowetsedwa kwa mpweya, potero kuchotsa ming'alu yaying'ono ya zokutira ndikupanga malo abwino osalala.

Gypsum pulasitala ndi pulasitala mankhwala

1. Limbikitsani kugwirizana, pangitsa kuti pulasitala ikhale yosavuta kufalitsa, komanso sinthani mphamvu yotsutsa-sagging kuti ipititse patsogolo madzi ndi kupopa. Potero kuwongolera magwiridwe antchito.

2. Kusungirako madzi kwapamwamba, kutalikitsa nthawi yogwira ntchito yamatope, ndikupanga mphamvu zamakina zapamwamba zikakhazikika.

3. Mwa kulamulira kusasinthasintha kwa matope kuti apange chophimba chapamwamba chapamwamba.

Mapulasitala opangidwa ndi simenti ndi matope amiyala

1. Limbikitsani kufanana, pangitsa kuti zikhale zosavuta kuvala matope otsekemera otenthetsera, ndikuwongolera mphamvu zotsutsana ndi kugwedezeka nthawi yomweyo.

2. Kusungirako madzi kwapamwamba, kukulitsa nthawi yogwira ntchito yamatope, kupititsa patsogolo ntchito yabwino, ndikuthandizira matope kuti apange mphamvu zamakina apamwamba panthawiyi.

3. Ndi kusungirako kwapadera kwa madzi, ndi koyenera kwambiri kwa njerwa zoyamwa madzi.

Panel joint filler

1. Kusunga madzi kwabwino kwambiri, komwe kumatha kutalikitsa nthawi yozizirira ndikuwongolera magwiridwe antchito. Kupaka mafuta ambiri kumapangitsa kuti kumanga kukhale kosavuta komanso kosavuta.

2. Sinthani kukana kwa shrinkage ndi kukana ming'alu, sinthani mawonekedwe apamwamba.

3. Perekani mawonekedwe osalala ndi ofanana, ndipo pangani malo omangirira mwamphamvu.

zomatira matailosi

1. Pangani zosakaniza zowuma zosavuta kusakaniza popanda zotupa, motero kusunga nthawi yogwira ntchito. Ndipo pangani ntchito yomangayo mwachangu komanso mogwira mtima, zomwe zimatha kupititsa patsogolo ntchito ndikuchepetsa mtengo.

2. Potalikitsa nthawi yoziziritsa, kuwongolera kwa matayala kumakhala bwino.

3. Perekani zotsatira zabwino zomatira, ndi kukana kwakukulu kwa skid.

zodziyimira pawokha pansi

1. Perekani mamasukidwe akayendedwe ndipo angagwiritsidwe ntchito ngati anti-sedimentation aid.

2. Kupititsa patsogolo madzimadzi ndi kupopera, potero kumapangitsa kuti pansi pakhale bwino.

3. Kuwongolera kusungidwa kwa madzi, potero kuchepetsa kwambiri kusweka ndi kuchepa.

Zopaka Pamadzi ndi Zochotsa Paint

1. Kutalikitsa moyo wa alumali poletsa zolimba kuti zisakhazikike. Kugwirizana kwabwino kwambiri ndi zigawo zina komanso kukhazikika kwachilengedwe kwachilengedwe.

2. Amasungunuka mwamsanga popanda zotupa, zomwe zimathandiza kuti kusakaniza kukhale kosavuta.

3. Kupanga madzi abwino, kuphatikizapo kuthirira pang'ono komanso kusanja bwino, komwe kungapangitse kutha kwapamwamba komanso kupewa utoto wowongoka.

4. Limbikitsani mamasukidwe akayendedwe a utoto wothira utoto wamadzi ndi organic zosungunulira utoto wochotsa, kuti chochotsa utoto zisatuluke kuchokera pamalowo.

zitsulo za konkriti zowonjezera

1. Limbikitsani machinability wa mankhwala extruded, ndi mkulu kugwirizana mphamvu ndi lubricity.

2. Kupititsa patsogolo mphamvu yonyowa ndi kumamatira kwa pepala pambuyo pa extrusion.
