Hydroxypropyl nothcellulose (hpmc) ndi cellulose yopanda ionic eyelil eyelil ogwiritsidwa ntchito kwambiri pomanga zida zomangira, mankhwala opangira mankhwala, chakudya, zodzoladzola ndi minda ina. Makamaka pakugwiritsa ntchito kolowera komanso kuphatikiza kolumikizira, hpmc kwakhala kofunikira chifukwa cha zovuta zake.
1. Makhalidwe oyambira a HPMC
HPMC ili ndi yotumphukira kwambiri, kusungidwa kwamadzi, zinthu zopangidwa ndi mafilimu, zomwe zimapangitsa kuti zizigwira ntchito yomanga. Choyamba, hpmc ndi ma cellulose osungunuka madzi omwe amatha kusungunuka m'madzi ozizira kuti apange njira yowonekera kapena yosinthira. Ili ndi madzi abwino kusungunuka ndi kukhazikika ndipo imatha kuwonjezera mafayilo a makina otsika. Kachiwiri, hpmc imakhala ndi madzi abwino kwambiri ndipo imatha kupanga filimu yoteteza padziko lapansi kuti isapewe madzi osasinthika mwachangu. Kuphatikiza apo, katundu wake wopanga mafilimu amalola kuti apange mafilimu owiritsa omwe amagwiritsa ntchito mphamvu zomwe zimawonjezera mphamvu ndi kuvala kukana.
2. Kugwiritsa ntchito HPMC mu othandizira
Caulk ndi zinthu zomwe zimagwiritsidwa ntchito kudzaza ming'alu ndi mipata pamitundu ya nyumba, nyumba ndi zida. Udindo wa HPMC mu Ogring Oglics amawonetsedwa makamaka pazotsatira:
Thickener: HPMC imatha kuwonjezera mawidwe obwera chifukwa cha omwe athandizidwa, kupangitsa kuti akhale ndi ntchito yabwino panthawi yomanga ndipo sikophweka ku Sags ndi Sag. Izi ndizofunikira kwambiri pamalo ofukula monga momwe manda.
Mtumiki wosunga madzi: Pogwiritsa ntchito othandizira olowera, kugwiritsa ntchito madzi osungirako madzi kumakhala kovuta kwambiri. Imatha kusunga bwino chinyezi, pewani chinyezi mu chokhachomera kwambiri pakuthana mwachangu nditamanga, ndipo pewani ming'alu ndi kufota chifukwa choyanika kwambiri. Izi sizongothandiza kukonza nthawi yofunsidwa kwa Kaulkiyo, komanso imawonjezera mphamvu zake komanso kulimba.
Mitundu ndi yosalala: HPMC ili ndi mafuta abwino, kupangitsa kuti oyang'anira akhale bwino panthawi yomanga komanso yosavuta kugwira ntchito. Zimathandizanso kusalala kwa kongulo, ndikupangitsa kuti chomalizidwa chikhale chosangalatsa.
3. Kugwiritsa ntchito HPMC mu count
Kuphatikiza kolumikizana kumagwiritsidwa ntchito kungodzaza ndikusindikiza kulumikizana pakati pa zinthu zosiyanasiyana m'nyumba kuti zilepheretse kulowa kwamadzi, mpweya ndi zodetsa. Kugwiritsa ntchito HPMC mu ophatikiza kuphatikiza chimodzimodzi, makamaka motere:
Modelion: HPMC imatha kusintha magwiridwe antchito a kuphatikiza, zomwe zimapangitsa kuti zikhale zomatira ndi maziko apansi ndikuletsa kusokonekera ndikuphwanya mafupa.
Kukhazikika komanso kusinthasintha: Popeza nyumba zidzamasula pang'ono posintha kutentha ndi chinyezi cholumikizira, mankhwala ophatikizika amafunika kukhala ndi vuto linalake komanso kusinthasintha. HPMC imatha kupatsa ntchito yolumikizirana, ndikupangitsa kuti ikhalebe yovuta panthawi yoyipa ndipo siosavuta kusweka.
Kukana Kukana: Zotsatira zopweteka za HPMC zitha kusintha zolimba za wophatikizana ndi zowonongeka ndi zowonongeka zomwe zimachitika chifukwa cha kupsinjika kwa chilengedwe.
4. Kukwaniritsa kugwiritsa ntchito HPMC
Ngakhale HPMC imagwiritsidwa ntchito kwambiri m'matumbo ndi kuphatikiza limodzi, pali zinthu zina zomwe zimafunikira kuti ikhale yofunika kwambiri pakugwiritsa ntchito. Choyamba, mtundu woyenera wa HPMC uyenera kusankhidwa malinga ndi malo omwe amagwiritsidwa ntchito ndi zida zoti agwiritse ntchito. Kachiwiri, kuchuluka kwa HPMC yowonjezeredwa kuyenera kulamulidwa mosamalitsa. Kuphatikizika kwambiri kungapangitse kuti zinthuzo zikhale zomata kwambiri ndipo zimakhudza kugwiritsidwa ntchito. Nthawi yomweyo, HPMC iyenera kutetezedwa ku chinyezi komanso kutentha kwambiri panthawi yosungirako komanso kunyamula popewa kuchepa kwa magwiridwe antchito.
Hydroxypylpyl methylcellulose (hpmc) amagwira ntchito yofunika kwambiri pakugwiritsa ntchito ma cauls ndi kuphatikiza limodzi. Sizongosintha magwiridwe antchito ndi moyo wankhanizo, komanso bwino maonekedwe ndi magwiridwe antchito. Ndi chitukuko cha zomangira zomangira, chiyembekezo cha ntchito cha HPMC chidzakhala chowonjezera.
