Kugwiritsidwa ntchito kwambiri pomanga, hydroxypropyl methylcellulose (hpmc) ndiowonjezera matope. Zimawonjezera katundu monga kugwirira ntchito, kusungidwa kwamadzi ndi kutsatira, potero kukonza magwiridwe antchito ndi mphamvu.
1. Kumvetsetsa HPMC ndi zabwino zake
1.1 Kodi hpmc ndi chiyani?
HPMC ndi ether cellulose yochokera ku cellulose yachilengedwe. Nthawi zambiri amagwiritsidwa ntchito popanga zomangamanga, makamaka zouma mafoni, chifukwa kuthekera kwake kusintha zinthu zakuthupi.
1.2 Ubwino wa HPMC ku matope
Kusungidwa kwamadzi: HPMC imathandizira kusungidwa kwamadzi, komwe ndikofunikira kuti simementi hydration, potengera mphamvu ndi kuchepetsa shrizage ndi kuchepetsa.
Kugwira Ntchito: Zimakuthandizani kugwirira ntchito matope, kupangitsa kuti ikhale yosavuta kuigwiritsa ntchito ndikufalikira.
Modelion: HPMC imawonjezera chotsatsa cha matope a matope a matope a matope a matope am'matontholo, kuchepetsa chiopsezo cha kumeta.
Anti-sag: Zimathandizira kuti azisunga matope ake pamalo owongoka osakusaka.
Nthawi yotseguka: hpmc imafikira nthawi yotseguka, yololeza nthawi yosintha ndikumaliza.
2. Mitundu ya HPMC ndi zotsatira zawo patavala matope
HPMC imapezeka mumitundu yosiyanasiyana, yosiyanitsidwa ndi mafayilo ndi gawo lotsatira:
Makutu: IscCen HPMC imathandizira kusungidwa kwamadzi komanso kugwirira ntchito, koma kumapangitsa kusakaniza kovuta. Makunja otsika amatuluka ali ndi kusungidwa kwamadzi koma savuta kusakaniza.
Gawo lolowa: Mlingo wazolowa zomwe zimakhudza kusungunuka ndi mafuta a gel osakaniza, zomwe zimakhudzanso magwiridwe antchito mosiyanasiyana.
3. Malangizo osakanikirana ndi hpmc ufa ndi matope
3.1 Kuganizira
Kugwirizana: onetsetsani kuti kalasi yosankhidwa ya HPMC imagwirizana ndi zina zowonjezera komanso mawonekedwe onse a matope.
Mlingo wa HPMC Mlingo wa hpmc umachokera ku 0.1% mpaka 0.5% mwa kulemera kwa kusakaniza kowirikirako. Sinthani malinga ndi zofunikira za pulogalamuyi.
3.2 Kusakaniza
Kusakaniza:
Sakanizani Zosakaniza: Sakanizani bwino ufa wa hpmc wokhala ndi zosakaniza zina zowuma (simenti, mchenga) kuwonetsetsa ngakhale kugawa ngakhale kugawa ngakhale kugawa.
Kusakaniza kwamakina: Gwiritsani ntchito katswiri wogwiritsa ntchito yunifolomu kusakanikirana. Kusakaniza kwa Maganizo sikungakwaniritse kufanana.
Zowonjezera:
Zowonjezera pang'onopang'ono: kuwonjezera madzi pang'onopang'ono ndikusakanikirana kuti musatseke. Yambitsani kusakanikirana ndi madzi ochepa kenako onjezerani ngati pakufunika.
Cheke cheni: kuwunika kusasinthika kwa matope kuti akwaniritse zomwe mukufuna. Kuchuluka kwa madzi kumawonjezeredwa kuyenera kuchepetsedwa kuti musathe kugwiritsa ntchito kusakaniza.
Kusakaniza Nthawi:
Kusakaniza koyambirira: Sakanizani zigawo za mphindi 3-5 mpaka osakanikirana amapezeka.
Nthawi yoyimirira: Lolani kusakaniza kukhala kwa mphindi zochepa. Nthawi iyi yopambanayi imathandizira kuyambitsa bwino HPMC, yowonjezera mphamvu yake.
Kusakaniza komaliza: Sakanizani kwa mphindi 1-2 musanagwiritse ntchito.
3.3 MALANGIZO OTHANDIZA
Kutentha ndi chinyezi: sinthani madzi ndikusakaniza nthawi malinga ndi nyengo yozungulira. Kutentha kwambiri kapena kutsika kotsika kumafunikira madzi owonjezera kapena kuchepetsedwa nthawi yotseguka.
Ukhondo wachida: Onetsetsani kuti zida zosakaniza ndi zokhunjezi ndizoyera kuti zisadetse kuipitsidwa ndi zotsatira zosagwirizana.
4. Malingaliro othandiza komanso ovutitsa
4.1 Kugwira ndikusunga
Sungani ufa wa hpmc mu malo ozizira, owuma kuti mupewe kuyamwa chipongwe ndi kutsekera.
Moyo wa alumali: Gwiritsani ntchito ufa wa hpmc mkati mwa alumali kuti atsimikizire bwino. Onani malangizo a wopanga zomwe amapereka mwatsatanetsatane.
4.2 Mavuto Ofala ndi Mayankho
Agglometration: hpmc akhoza kuphika ngati madzi amawonjezeredwa mwachangu kwambiri. Kuti mupewe izi, nthawi zonse muziwonjezera madzi pang'onopang'ono ndikusuntha mosalekeza.
Kusakaniza kosalekeza: Kusakanikirana kwamakina kumalimbikitsidwa kuti ngakhale kugawanidwe. Kusakaniza dzanja kumatha kubweretsa zosagwirizana.
Kusaka:
4.3 Chikumbutso Chachilengedwe
Zotsatira zake: Kutentha kwambiri kumathandizira kukhazikitsa ndikuwuma matope. Sinthani Mlingo wa HPMC kapena Madzi omwe ali nawo.
Chinyezi cha chinyezi: chinyezi chotsika mtengo chimatha kukulitsa kuchuluka kwa eyapa, ndikufunika kusintha kwa kuchuluka kwa madzi osungika ndi HPMC.
5. Malangizo apamwamba pakukulitsa ntchito
5.1 Kusakaniza ndi zina zowonjezera
Kuyesa kwa Kugwirizana: Mukasakaniza HPMC yokhala ndi zina zowonjezera monga kutentha kwa madzi ambiri, obwezeretsa, kapena othamanga, kuchita zoyeserera.
Kusakaniza kotsatira: Onjezani HPMC ndi zina zowonjezera mu dongosolo linalake kuti mupewe kuyanjana komwe kungakhudze magwiridwe antchito.
5.2 Kutsetsa Mlingo
Woyendetsa: Phatikizani mayeso a woyendetsa ndege kuti adziwe kuchuluka koyenera kwa HPMC kwa kusakaniza kwina kwa matope.
Sinthani: Chitani zinthu zosintha pa mayankho ogwiritsira ntchito kuchokera ku mapulogalamu.
5.3 Kuchulukitsa Konse
Pogwiritsa ntchito: Ganizirani kuphatikiza hpmc ndi madzi ochepetsa madzi kuti athetse kugwira ntchito popanda kusokoneza mphamvu.
Posunga madzi: ngati kukonza madzi kukulimbikitsidwa kumafunikira nyengo yotentha, gwiritsani ntchito kalasi yapamwamba ya hpmc.
Kusakaniza bwino kwa HPMC Kuzindikira komwe kumagwiritsira ntchito ma hpmc ndikutsatira njira zoyenera kusakanikirako ndikofunikira pakukonza matope a matope pantchito zomanga. Pomvera mtundu wa hpmc yomwe imagwiritsidwa ntchito, kulingalira kwa mapangidwe ake, komanso malangizo othandiza, mutha kuwononga matope okwanira, omwe ali ndi mavalidwe abwino kwambiri omwe ali ogwirizana ndi zosowa zanu zapadera.
