1. Mavuto ofala mu ufa wa putty
uma mofulumira
Izi makamaka zimagwirizana ndi kuchuluka kwa ufa wa calcium wowonjezeredwa (wochuluka kwambiri, kuchuluka kwa ufa wa calcium wogwiritsidwa ntchito mu fomula ya putty kungachepetsedwe moyenera) ndi kuchuluka kwa madzi osungira hydroxypropyl methylcellulose (HPMC), komanso zimagwirizana ndi kuuma kwa khoma.
Kuchotsa ndi kupukuta
Izi zikugwirizana ndi kuchuluka kwa madzi omwe amasungidwa, komwe kumakhala kosavuta kuchitika pamene kukhuthala kwa hydroxypropyl methylcellulose (HPMC) kuli kochepa kapena kuchuluka komwe kumawonjezedwa kuli kochepa.
Kuchotsa ufa wa putty wamkati mwa khoma
Izi zikugwirizana ndi kuchuluka kwa ufa wa calcium wa phulusa (kuchuluka kwa ufa wa calcium wa phulusa mu fomula ya putty ndi kochepa kwambiri kapena kuyera kwa ufa wa calcium wa phulusa ndi kochepa kwambiri, ndipo kuchuluka kwa ufa wa calcium wa phulusa mu fomula ya putty ufa kuyenera kuwonjezeredwa moyenera), ndipo kumagwirizananso ndi kuchuluka kwa hydroxypropyl methyl. Kuchuluka kwa base cellulose (HPMC) kumagwirizana ndi mtundu, womwe umawonetsedwa mu kuchuluka kwa madzi omwe amasungidwa mu chinthucho. Kuchuluka kwa madzi omwe amasungidwa ndi kochepa, ndipo nthawi ya ufa wa calcium wa phulusa (calcium oxide mu ufa wa calcium wa phulusa sikusintha kwathunthu kukhala calcium hydroxide) sikokwanira. , chifukwa.
kuphulika
Izi zikugwirizana ndi chinyezi chouma komanso kusalala kwa khoma, komanso zikugwirizana ndi kapangidwe kake.
malo olowera
Izi zikugwirizana ndi cellulose, yomwe ili ndi mphamvu zochepa zopangira filimu. Nthawi yomweyo, zonyansa zomwe zili mu hydroxypropyl methylcellulose (HPMC) zimakhudzidwa pang'ono ndi phulusa la calcium. Ngati vutoli lili lalikulu, ufa wa putty udzakhala ngati zotsalira za nyemba. Sungayikidwe pakhoma, ndipo ulibe mphamvu yogwirizana nthawi imodzi. Kuphatikiza apo, zinthu monga hydroxypropyl methylcellulose (HPMC) zosakanikirana ndi gulu la carboxymethyl zimawonekeranso pamenepa.
Mapiri amoto ndi mabowo a pincane akuwonekera
Izi zikuonekeratu kuti zikugwirizana ndi mphamvu ya pamwamba pa madzi ya yankho lamadzi la hydroxypropyl methylcellulose (HPMC). Mphamvu ya madzi ya yankho lamadzi la hydroxyethyl si yodziwikiratu. Zingakhale bwino kuchita chithandizo chomaliza.
Putty ikauma, zimakhala zosavuta kusweka ndikukhala wachikasu
Izi zikugwirizana ndi kuwonjezera ufa wambiri wa phulusa-calcium. Ngati ufa wa phulusa-calcium wochuluka kwambiri, kuuma kwa ufa wa putty kumawonjezeka mukawuma. Ngati ufa wa putty ulibe kusinthasintha, umasweka mosavuta, makamaka ukagwiritsidwa ntchito ndi mphamvu zakunja. Zimagwirizananso ndi kuchuluka kwa calcium oxide mu ufa wa phulusa-calcium.
2. N’chifukwa chiyani ufa wa putty umachepa mukawonjezera madzi?
Hydroxypropyl methylcellulose (HPMC) imagwiritsidwa ntchito ngati chokhuthala komanso chosunga madzi mu mafuta. Chifukwa cha thixotropy ya hydroxypropyl methylcellulose (HPMC), hydroxypropyl methylcellulose mu ufa wa putty. Kuwonjezera kwa HPMC kunayambitsanso thixotropy mutawonjezera madzi mu putty. thixotropy iyi imachitika chifukwa cha kuwonongeka kwa kapangidwe ka zinthu zomwe zili mu ufa wa putty. Kapangidwe kameneka kamachitika pakapuma ndipo kamasweka chifukwa cha kupsinjika. Izi zikutanthauza kuti, kukhuthala kumachepa mukasakaniza, ndipo kukhuthala kumabwereranso mukayima.
3. Kodi chifukwa chiyani putty imakhala yolemera pang'ono poikanda?
Pankhaniyi, kukhuthala kwa hydroxypropyl methylcellulose (HPMC) komwe kumagwiritsidwa ntchito nthawi zambiri kumakhala kokwera kwambiri, ndipo opanga ena amagwiritsa ntchito yuan 200,000 popanga putty. Putty yomwe imapangidwa mwanjira iyi imakhala ndi kukhuthala kwakukulu, kotero imamira ikakwezedwa. Kuchuluka kovomerezeka kwa putty pamakoma amkati ndi 3-5 kg, ndipo kukhuthala ndi 80,000-100,000.
4. N’chifukwa chiyani mukuganiza kuti kukhuthala kwa hydroxypropyl methylcellulose (HPMC) komwe kumakhala kukhuthala komweko kumasiyana nthawi yozizira ndi chilimwe?
Chifukwa cha kutentha kwa chinthucho, kukhuthala kwa putty ndi matope kumachepa pang'onopang'ono kutentha kukakwera. Kutentha kukapitirira kutentha kwa gel kwa chinthucho, chinthucho chimachotsedwa m'madzi ndikutaya kukhuthala kwake. Kutentha kwa chipinda nthawi zambiri kumakhala kopitilira madigiri 30, zomwe zimasiyana kwambiri ndi kutentha kwa nthawi yozizira, kotero kukhuthala kumakhala kotsika. Ndikofunikira kusankha chinthu chokhala ndi kukhuthala kwakukulu mukamagwiritsa ntchito chinthucho nthawi yachilimwe, kapena kuwonjezera kuchuluka kwa hydroxypropyl methylcellulose (HPMC), ndikusankha chinthu chokhala ndi kutentha kwa gel kokwera.
