Hydroxypypyl methyl cellulose ndi gawo la simenti

Kodi hpmc hydroxypypyl ndi chiyani methyl cellulose ndi gawo la simenti?

Matope opangira matope, mawonekedwe ake amadalira ukonde wofanana ndi zopangira zopangira: konkritihydroxypropyl methyl cellulose7-9, Sicon Carbide ufa 40-45, calcium hydroxide ufa 10-20, alungun clefate 4-6, ma carbongch alumphuka 4-4, madzi 600-650; Matalala amadzimadzi okumba amatulutsa izi amakhala ndi kutentha kwamphamvu, kutengera moto wabwino, kutengeka kwakukulu, kutetezedwa kwabwino, kupewa kugwa. Lero tikambirana za mamasukidwe a hydroxypropyl methy cellulose solution ndi zonse? Tiziwerenga.

1. Kuchepetsa kwachibale, kutentha kwa njira yam'madzi, kudula mitengo ndi njira yoyesera ya cellulose ether ether. 2. Kutentha kwagalasi kumachitika, kutentha kwakukulu kwa chinsinsi, mafayilo ndi mwachilengedwe; 3. Wokwera bwino wa cellulose ether, mawilo owoneka bwino a njirayi, kotero pakukonzekera kugwiritsa ntchito kuchuluka kwa kuphatikiza kwake, molunjika matope a simenti ndi simenti; 4. Monga njira yambiri yothetsera vutoli, mafanowo adzachepetsa ndi kuwonjezeka kwa kutentha, kuphatikiza kuchuluka kwa cellulose ether ether, kuvulaza kwakukulu kwa kutentha; Kuphatikiza apo, zotsatira za kukula kwenikweni zimasiyananso malinga ndi kuchuluka kwa madzi omwe amagwiritsidwa ntchito simenti ya epoxy.

Hydroxypyl methl cellulose yankho la ma visccy limakhalanso lalikulu la ndemanga pama cellulose ether, koma ngati ma virus a centramer a rallity. Ponena za matope ena omwe ali ndi madzi ambiri, mamasukidwe a ethel ether atchulidwa kuti akhale otsika.

Cellulose ether magazine yankho ndi thupi la pseudoplastication, m'mbuyomu la kupezeka kwa mtengo wamphongo ndi lalikulu, ma visccy amachepera.

Chifukwa chake, kuti chivundi chizikhala: Chiyanjano cha matope a sing'anga chidzachepetsedwa ndi mphamvu yakunja, zomwe zimapindulitsa pakupanga kwa ukadaulo, koma kuchitika kwa cellulose.

Kusunga kwamadzi ku hydroxypropyl methy cellose ndi imodzi mwazinthu zofunikira za hydroxypropyl celloluse. Mlingo wa madzi zam'madzi mu matope osakanikirana ndi zopangidwa ndi mapulaneti amakhudzidwa ndi kutentha kwa mpweya, kutentha komanso kuthamanga. Chifukwa chake, munthawi zosiyanasiyana, kuphatikiza hydroxypropyl methl cellulose kuchuluka kwa madzi omwe ali ndi vuto linalake.

Mwambiri, mafayilo apamwamba a hydroxpyupyl methy cellose, koma njira yabwino yosungira madzi idzakhalapo, koma kuvulaza kwa mafayilo kumatha kupitilira 100,000 MPA. s. Pamene mafayilo a hydroxypypyl celyl cellulose imaposa 100,000, kuchuluka kwa madzi kumatha kusintha kwakukulu ndikukulitsa kuchuluka kwa hydroxypropyl cellulose.

Pazomanga mwatsatanetsatane, madzi osungira madzi amatha kusinthidwa ndikusintha kuchuluka kwa hydroxypropyl pa cellulose. Hydroxypropyl methl cellulose malonda amatha kuthana bwino ndi vuto la kusungidwa kwamadzi pansi pa kutentha kwambiri. Mu nyengo yotentha kwambiri, makamaka m'malo otentha komanso otopetsa komanso kapangidwe kake ka hydroxypropyl, ma hydroxypropyl, ma hydroxypropyl, ma hydroxypropyl a meth

Kuchuluka kwa hydroxypropyl methyl cellulose, imakhala ndi gawo labwino, komanso mpweya wa melyen aldecy madzi amtsinje, kusungidwa kwamadzi kwambiri.

Mulingo wapamwamba wa hydroxypropyl meth cellulose amatha kukhala ndi malo omasuka matope ndi malo okhazikika, ndikutsimikizira kuti mgwirizano wa ordrate umakhala ndi mphamvu yayikulu. Mu chidani kutentha kwambiri chilimi yomanga chilimwe, chifukwa chake, kuti tifikire madzi, ziyenera kukhala mogwirizana ndi kuchuluka kwa ma hydroxypropyl, kuchepetsa, kuwonetsa kuti ndi zovuta kwambiri. Pamene kutentha kumadontha, kuchuluka kwa hydroxypropyl meth cellulose amatha kuchepetsedwa pang'onopang'ono ndipo madzi omwewo atha kukwaniritsidwa.

Ngati ma cellulose ether sawonjezedwa, matope a matope atsopano a Stemer awume, sangakhale ndi matope mwanjira yachilendo, chifukwa cha matope a simenti sichingakhale cholimba komanso kukhala ndi chotsatsa. Nthawi yomweyo, kuwonjezera kwa cellulose ether ether kumapangitsa matope a simenti kukhala ndi maulendo abwino komanso kusinthasintha, ndikusintha ubale wolimba wa matope a simenti.

1, hydroxypropyl methyl cellulose tinthu tating'onoting'ono

Kukula kwa tinthu tambiri ya cellulose ehan kumavulaza kusumuli. Ma ether a celluuse ether ndi, kuthamanga kwake kumadzimadzi m'madzi ndi kukwera kwa madzi. Chifukwa chake, tinthu tating'onoting'ono ta mulhuo muyenera kuphatikizidwa pakufufuza kwa mawonekedwe ake. Mwambiri, cellulose ether tinthu tating'ono ta 80 mesh potengera.

2, hydroxypropyl methl cellulose youma popanda mphamvu yokoka

Wowuma Manic Palibe mumtima wakuda, amatanthauza kutentha kwina kwa masiketi a cellulose, kutayika kwa mawonekedwe a mankhwala kuwerengedwa koyambirira kwa mawonekedwe. For a certain quality of cellulose ether in the dry without gravity rate is too high, will reduce the relevant components in cellulose ether, harm the actual effect of the use of downstream companies, but also improve the purchase cost. Nthawi zambiri ma cellulose owuma ether popanda kuchuluka kwa mphamvu sadzapitirira 5.0%.

3, hydroxypropyl methyl cellulose potaziyamu phulusa

Kwa mtundu wina wa ma cellulose mu phulusa ndi lalitali kwambiri, limachepetsa kuchuluka kwa ma cellulose omwe ali ndi ma compani ocheperako, cellulose ether postain kukula kwa mawonekedwe ake.

4, hydroxypropyll methyl cellulose

Hydroxypyl nothl cellulose madzi kusungidwa ndi kukula kwake ndi njira yowonjezera matope a centery ether etherner.

5, hydroxypropyll methyl cellulose p

Makutu a hydroxypropyl cellouse pa cellulose amachepetsa pang'onopang'ono pamtunda wautali, makamaka pazogulitsa zazitali, motero mtengo wa mafawu uyenera kukhala wochepa. Nthawi zambiri zimafotokozedwa kuti gulu la PH Lofunika la cellulose ether iyenera kugwira ntchito ngati 5-9.

6. Tumizani ku Hydroxypropyl Meth Celyose

Ubwino ndi zovuta za kupatsirana kwa hydroxypropyl meth cellulose imatha kukhudza mwachindunji pazomwe amagwiritsa ntchito. Zofunika kwambiri zomwe zimapangitsa kupatuka kwa cellulose ether1) mtundu wa zopangira; (2) Zotsatira zenizeni zosemedwa; (3) Kukonzekera usilikali; (4) Wopanga zinthu zachilengedwe; (5) Zotsatira zenizeni za Zhongo.

Malinga ndi ntchito zenizeni, kupatsirana kwa cellulose ether sikuyenera kukhala kochepera 80%.

7, hydroxypropyll methyl cellulose kutentha

Hydroxypropyl mealose mu ziwalo za simenti monga chinsinsi chotsatsa, mawonekedwe am'madzi ndipo kutentha kwa gelroxypropyl centull. Kutentha kumagwiritsidwa ntchito kuweruza mtundu ndi kufotokozera kwa ethel ether, komanso kuchuluka kwa milingo yama etheluse ether ether.

8. Kuphatikiza apo, mchere komanso wotsalira chidzavulaza kutentha kwa guluu. Pamene kutentha kwa yankho la madzi kumakwera, chibendeni polymer pang'onopang'ono kumakhala kosowa madzi, ndikuwoneka kuti yankho la madzi limachepa. Pamene zotsamba za kufikiridwa zimafikiridwa, polimayo imawuma kwathunthu ndipo zomatira zimapangidwa. Chifukwa chake, kutentha kogwira ntchito kwa mamembala nthawi zambiri kumakhala pansi pa kutentha koyambirira. Pansi pa muyeso uwu, kutsika kwa kutentha, kukweza mafalo, komanso kofunikira kwambiri kusinthika kwa ma virus ndi kusungidwa kwamadzi.
