Phutuli wa ufa wa punty nthawi zambiri amatanthauza chodabwitsa kuti pamwamba popanga putty ndi ufa nditatha pambuyo pomanga mgwirizano, womwe ungakhudze mphamvu yomanga ndi kukhazikika. Izi zikufanana ndi zinthu zambiri, chimodzi mwazomwe ndikugwiritsa ntchito komanso mtundu wa hydroxypypyl methylcellulose (hpmc) mu ufa.
1. Udindo wa HPMC mu ufa
Hpmc, monga chowonjezera chogwiritsidwa ntchito kawirikawiri, chimagwiritsidwa ntchito kwambiri popanga zida, kuphatikiza ufa, matope, guluu, etc. Ntchito zazikulu zimaphatikizapo:
Kukula Kwakukulu: HPMC imatha kuwonjezera kusasinthika kwa ufa wa putty, kupanga zomangamanga ndikupewa kutsika kapena kutuluka kwa putty ufa pomanga.
Kusungidwa kwamadzi: HPMC ili ndi chisungiko chabwino chamadzi, chomwe chingakweze kubizinesi ya putty ndikuletsa kutsuka kwa madzi mwachangu kwambiri nthawi yowuma, chifukwa cha kusokonekera kapena shrinka.
Mode: HPMC imatha kuwonjezera cholumikizira cha putty ufa, kuti ithe kutsatira khoma kapena gawo lina, kuchepetsa kuchitika kwa zovuta monga mabowo ndikugwa.
Sinthani magwiridwe antchito: Kuchulukitsa HPMC ku Phmmc kutsuka ufa kumatha kukonza madzi ndi zomangamanga, kupanga magwiridwe antchito, ndikuchepetsa zinyalala.
2. Zifukwa zopeweka ufa wa punty
Phulani ufa wa putty ufa ndi vuto wamba pazifukwa zovuta, zomwe zingakhale zokhudzana ndi zinthu zotsatirazi:
Vuto lapamwamba: Madzi a mayamwidwe amakhala olimba kwambiri, ndikupangitsa kuti putty kutaya chinyontho mwachangu ndikuchepetsa osakwanira, zomwe zimayambitsa kuluka.
Vuto la Puti Lanu: Njira zosayenera za ufa, monga kuchuluka kwa zinthu zosafunikira, monga simenti, gypsum, etc.), idzakhudzanso mphamvu ndi kukhazikika kwamphamvu.
Chovuta chomangira: Kupanga kosiyanasiyana, kutentha kwambiri kapena kutentha kotsika kungayambitsenso ufa kuwuma panjira yowuma.
Kukonzanso zosayenera: Kulephera kusungabe kuvulira patapita nthawi yomanga kapena kupitirira motsatira kungakhale ndi ufa wa putty kuti uzipukuta popanda kuwuma.
3. Ubwenzi wapakati pa HPMC ndi purserization
Monga wokulirapo ndi wololera wa madzi, ntchito ya HPMC mu punty ufa imakhudza kwambiri mtundu wa punty. Mphamvu ya hpmc pa ufa imawonetsedwa makamaka ndi izi:
(1) Mphamvu ya Kusungidwa kwamadzi
Pulofu ya ufa ya putty nthawi zambiri imakhala yokhudzana ndi madzi ofulumira omwe amakhala pamwamba. Ngati kuchuluka kwa HPMC yowonjezeredwa sikokwanira, ufa wa punty umataya madzi mwachangu nthawi yowuma ndikulephera kukonza kwathunthu, chifukwa cha ufa wa ufa. Kusunga kwamadzi kwa HPMC kumathandizira kusunga chinyezi choyenera panthawi yowuma, kulola kuti kutchinjiriza pang'onopang'ono kuwumiriza komanso kupewa ufa woyambitsidwa ndi madzi achangu mwachangu. Chifukwa chake, kusasunga kwamadzi kwa HPMC ndikofunikira kuti muchepetse ufa.
(2) Mphamvu ya kukula kwamphamvu
HPMC imatha kuwonjezera kusasinthika kwa putty ufa, kotero kuti kukhazikika kumatha kuphatikizidwanso ndi gawo lapansi. Ngati mtundu wa hpmc ndi wosauka kapena umagwiritsidwa ntchito molakwika, zimakhudza kusagwirizana kwa ufa wa punty, zomwe zimapangitsa kuti madzi ake asakhale osagwirizana, omwe angapangitse ufa wowuma kwambiri kwanuko mwachangu kwambiri, potero kuyambitsa ufa. Kuphatikiza apo, kugwiritsa ntchito HPMC mopitirira muyeso kudzapangitsanso pansi ufa wa putty kukhala kovuta kwambiri mukamanga, kumakhudza kutsatira pamodzi ndi zokutira ndi kutulutsa ufa.
(3) Synergy ndi zinthu zina
Mu ufa wa putty, hpmc nthawi zambiri amagwiritsidwa ntchito limodzi ndi zinthu zina zophatikizira (monga simenti, gypsum) ndi mafilimu (monga mafilimu). Kuchuluka kwa HPMC yomwe imagwiritsidwa ntchito ndi synergys ndi zinthu zina zimakhudza kwambiri magwiridwe ake. Njira yopanda tanthauzo imatha kubweretsa mphamvu yokwanira ya ufa ndi pomaliza pake zimabweretsa ufa. Kugwiritsa ntchito bwino HPMC kungathandize kukonza momwe mukugwiritsira ntchito ndikulimbana ndi kuchepetsa vuto la ufa chifukwa chosakwanira kapena zinthu zosagwirizana.
4. Mavuto a HPMC aliwonse amatsogolera
Kuphatikiza pa kuchuluka kwa HPMC yomwe imagwiritsidwa ntchito, mtundu wa hpmc pawokha ungakhudzenso mapangidwe a punty. Ngati mtundu wa HPMC suli muyezo, monga ma cellulose ochepa ndi magwiridwe osawoneka bwino, izi zimakhudza mwachindunji chitetezero chamadzi, zomanga ndi mphamvu zokhala ndi ufa. Zotsika HPMC sikovuta kupereka madzi okhazikika komanso kukula kwamphamvu, koma ingayambitsenso kuwopa, kuperewera ndi mavuto ena pakuwuma. Chifukwa chake, kusankha HPMC yapamwamba kwambiri ndikofunikira kuti tipewe mavuto a mafano.
5. Zotsatira zina pa ufa
Ngakhale HPMC imachita mbali yofunika kwambiri mu ufa wa putty, phulira nthawi zambiri limachitika chifukwa chophatikizidwa ndi zinthu zambiri. Zinthu zotsatirazi zingayambitsenso ufa:
Mikhalidwe Yachilengedwe: Ngati kutentha ndi chinyezi kwa malo omangayi ndizokwera kwambiri kapena kutsika kwambiri, zimakhudza kuthamanga kwa ufa wa punty.
Chithandizo choyenera:
Zovuta za ptty
Phenomenon wa punty ufa umagwirizana kwambiri ndi kugwiritsa ntchito HPMC. Ntchito yayikulu ya hpmc mu punty ufa ndi madzi osasunthika. Kugwiritsa ntchito moyenera kumatha kusintha nthawi ya ufa. Komabe, kupezeka kwa ufa kumadalira osati ku HPMC kokha kokha pa HPMC, komanso pazomwe monga njira monga mawonekedwe a ufa, gawo la mankhwala, ndi malo omanga. Pofuna kupewa vuto la ufa, ndikofunikira kusankha kapangidwe ka HPMC, njira yoyenerera, ukadaulo womanga wa sayansi komanso malo abwino omanga.
