Zosavuta komanso mwachilengedwe kusiyanitsa mtundu ndi kugwiritsa ntchito kwa HPMC

Kodi hydroxypropyl methylcellulose amagwiritsidwa ntchito bwanji?

——Yankho: HPMC imagwiritsidwa ntchito kwambiri pomanga, zokutira, utomoni wopangira, zoumba, mankhwala, chakudya, nsalu, ulimi, zodzoladzola, fodya ndi mafakitale ena. HPMC akhoza kugawidwa mu kalasi yomanga, kalasi chakudya ndi kalasi mankhwala malinga ndi cholinga. Pakali pano, zinthu zambiri zapakhomo ndizomangamanga. Pomanga kalasi, ufa wa putty umagwiritsidwa ntchito mochuluka, pafupifupi 90% umagwiritsidwa ntchito ngati putty ufa, ndipo enawo amagwiritsidwa ntchito ngati matope a simenti ndi guluu.

Kodi mungasiyanitse bwanji mtundu wa HPMC mosavuta komanso mwachilengedwe?

——Yankho: (1) Kuyera: Ngakhale kuyera sikungadziwe ngati HPMC ndi yosavuta kugwiritsa ntchito, ndipo ngati zopangira zoyera zikuwonjezeredwa panthawi yopanga, zimakhudza ubwino wake. Komabe, zinthu zambiri zabwino zimakhala ndi zoyera zabwino. (2) Fineness: Ubwino wa HPMC nthawi zambiri umakhala ndi mauna 80 ndi mauna 100, ndipo mauna 120 ndiwocheperako. HPMC yambiri yopangidwa ku Hebei ndi 80 mesh. Kukongoletsedwa bwino, kunena zambiri, kumakhala bwinoko. (3) Kutumiza kowala: ikani hydroxypropyl methylcellulose (HPMC) m'madzi kuti mupange colloid yowonekera, ndikuyang'ana kuwala kwake. Kuchuluka kwa kuwala kwamagetsi, kumakhala bwinoko, kusonyeza kuti muli ma insolubles ochepa mmenemo. . The permeability wa ofukula riyakitala zambiri zabwino, ndi yopingasa riyakitala ndi zoipa, koma sizikutanthauza kuti khalidwe ofukula riyakitala kuposa yopingasa riyakitala, ndi mankhwala khalidwe anatsimikiza ndi zinthu zambiri. (4) Mphamvu yokoka yeniyeni: Kuchuluka kwa mphamvu yokoka kwapadera, ndikolemera kwambiri. Kutsimikizika ndi kwakukulu, makamaka chifukwa zomwe zili mugulu la hydroxypropyl momwemo ndizazikulu, ndipo zomwe zili mugulu la hydroxypropyl ndizokwera, kusungirako madzi kuli bwino. (5) Kuwotcha: Tengani kachigawo kakang’ono kachitsanzocho n’kuchiotcha ndi moto, ndipo chotsaliracho choyeracho ndi phulusa. Zinthu zoyera kwambiri, zimayipitsitsa kwambiri, ndipo palibe zotsalira muzinthu zoyera.

Kodi mtengo wa hydroxypropyl methylcellulose ndi wotani?

—–Yankho; mtengo wa hydroxypropylmethyl umadalira chiyero chake ndi phulusa. Kukwera kwa chiyero, kuchepa kwa phulusa, kumakwera mtengo. Apo ayi, kutsika kwa chiyero, kukhala ndi phulusa, kutsika mtengo. Toni mpaka 17,000 yuan pa toni. 17,000 yuan ndi chinthu choyera chomwe chilibe zonyansa. Ngati mtengo wa unit uli wapamwamba kuposa 17,000 yuan, phindu la wopanga lawonjezeka. Ndizosavuta kuwona ngati mtunduwo ndi wabwino kapena woyipa malinga ndi kuchuluka kwa phulusa mu hydroxypropyl methylcellulose.

Ndi viscosity yanji ya hydroxypropyl methylcellulose yomwe ili yoyenera putty ufa ndi matope?

—–Yankho; ufa wa putty nthawi zambiri umakhala 100,000 yuan, ndipo chofunikira pamatope ndi apamwamba, ndipo chimafunika 150,000 yuan kuti chikhale chosavuta kugwiritsa ntchito. Komanso, ntchito yofunika kwambiri ya hydroxypropyl methylcellulose ndikusunga madzi, ndikutsatiridwa ndi makulidwe. Mu ufa wa putty, malinga ngati kusungirako madzi kuli bwino ndipo kukhuthala kuli kochepa (70,000-80,000), ndizothekanso. Inde, mamasukidwe amphamvu omwe ali pansi pa 100,000 ndi apamwamba, ndipo kusungirako madzi ndikwabwinoko. Pamene mamasukidwe akayendedwe amaposa 100,000, mamasukidwe akayendedwe amakhala ndi zotsatira pa kusunga madzi Zotsatira zake si zazikulu.
