yambitsani:
Ma ether a cellulose amagwiritsidwa ntchito kwambiri mumakampani omanga chifukwa cha mphamvu zawo zabwino zosungira madzi, kukhuthala, ndi kugwirizana. Amawongolera kuyenda ndi kusinthasintha kwa zinthu zopangidwa ndi simenti komanso kukonza mphamvu za makina a chinthu chomaliza. Ma putty amagwiritsidwa ntchito kwambiri mumakampani omanga kuti azitha kudzaza ming'alu, mabowo ndi zolakwika zina m'makoma ndi padenga. Kugwiritsa ntchito ma ether a cellulose mu ufa wa putty kungathandize kuti chinthucho chigwire ntchito bwino, nthawi yoikika komanso mtundu wake wonse. Nkhaniyi ikambirana za momwe ma ether a cellulose amagwirira ntchito bwino pa ufa wa putty.
Mitundu ya ethers ya cellulose:
Pali mitundu yosiyanasiyana ya ma ether a cellulose kuphatikizapo methylcellulose (MC), hydroxypropylmethylcellulose (HPMC), ethylcellulose (EC) ndi carboxymethylcellulose (CMC). HPMC ndi ether yotchuka ya cellulose mumakampani omanga chifukwa cha kusunga madzi bwino, kukhuthala komanso mphamvu zake zomatira. HPMC imabwera m'njira zosiyanasiyana, kuyambira yotsika mpaka yokwera.
Zotsatira za ether ya cellulose pa ufa wa putty:
Ufa wa putty umagwiritsidwa ntchito kudzaza ming'alu, mabowo ndi zolakwika zina m'makoma ndi padenga. Kugwiritsa ntchito ma ether a cellulose mu ufa wa putty kungathandize kuti chinthucho chigwire ntchito bwino komanso nthawi yake ikhazikike. Cellulose ether ingathandizenso kuti ufa wa putty ugwire ntchito bwino komanso kuti ukhale wolimba. Izi ndi zotsatira za kukhuthala kosiyanasiyana kwa ma ether a cellulose pa ufa wa putty:
1. Kukhuthala kochepa kwa HPMC:
Kukhuthala kochepa kwa HPMC kumatha kupititsa patsogolo kusinthasintha ndi kugwira ntchito kwa ufa wa putty. Kumathandizanso nthawi yokhazikika ya chinthucho. Kukhuthala kochepa kwa HPMC kumakhala ndi kutentha kochepa kwa gelation, komwe kungalepheretse ufa wa putty kuuma mwachangu. Kungathandizenso kulimbitsa ndi kugwirizana kwa chinthucho. Kukhuthala kochepa kwa HPMC ndi koyenera ufa wa putty womwe umafuna kugwira ntchito bwino komanso kusalala.
2. Kukhuthala kwapakati kwa HPMC:
HPMC yokhuthala yapakatikati imatha kukonza mphamvu za thixotropic za ufa wa putty. Imathanso kukonza mphamvu zosungira madzi ndi mgwirizano wa chinthucho. HPMC yokhuthala yapakatikati imatha kukonza mphamvu za makina a chinthucho, monga mphamvu ndi kulimba. Ndi yoyenera ufa wa putty womwe umafuna kusunga bwino madzi ndi mgwirizano.
3. Kukhuthala kwakukulu kwa HPMC:
HPMC yokhala ndi kukhuthala kwakukulu imatha kukulitsa kukhuthala ndi kuletsa kutsika kwa ufa wa putty. Imathanso kukulitsa kusunga madzi ndi kugwira ntchito kwa chinthucho. HPMC yokhala ndi kukhuthala kwakukulu imatha kukulitsa mphamvu za makina a chinthucho, monga mphamvu ndi kulimba. Ndi yoyenera ufa wa putty womwe umafuna kukhuthala kwakukulu komanso kuletsa kutsika.
Pomaliza:
Ma cellulose ether amagwiritsidwa ntchito kwambiri mumakampani omanga chifukwa cha mphamvu zawo zabwino zosungira madzi, kukhuthala, ndi kugwirizana. HPMC yakhala ether yotchuka ya cellulose mumakampani omanga chifukwa cha mphamvu zake zabwino. HPMC imabwera m'njira zosiyanasiyana, kuyambira yotsika mpaka yapamwamba. Kugwiritsa ntchito ma cellulose ether okhala ndi kukhuthala kosiyanasiyana kungathandize kukonza magwiridwe antchito, nthawi yoikika, magwiridwe antchito a thixotropic, kusunga madzi, kugwira ntchito bwino kwa ma bonding, komanso mphamvu zamakaniko a ufa wa putty. Kugwiritsa ntchito ma cellulose ethers kungathandize kukonza ubwino ndi magwiridwe antchito a ufa wa putty, zomwe zimapangitsa kuti ugwiritsidwe ntchito m'makampani omanga.
