Kugwiritsa ntchito hydroxypropyl methylcellulose, momwe mungasiyanitsire mtundu wa HPMC mosavuta komanso mwachilengedwe

Kodi ntchito yaikulu ya hydroxypropyl methylcellulose ndi yotani?

——Yankho:HPMCimagwiritsidwa ntchito kwambiri pa zipangizo zomangira, zokutira, ma resini opangidwa, zinthu zomangira, mankhwala, chakudya, nsalu, ulimi, zodzoladzola, fodya ndi mafakitale ena. HPMC ikhoza kugawidwa m'magulu omangira, chakudya ndi mankhwala malinga ndi cholinga chake. Pakadali pano, zinthu zambiri zapakhomo ndi zapakhomo. Mu gawo lomangira, ufa wa putty umagwiritsidwa ntchito kwambiri, pafupifupi 90% imagwiritsidwa ntchito pa ufa wa putty, ndipo wotsalawo amagwiritsidwa ntchito pa simenti ndi guluu.

Kodi mungasiyanitse bwanji khalidwe la HPMC mosavuta komanso mwachilengedwe?

——Yankho: (1) Kuyera: Ngakhale kuyera sikungadziwike ngati HPMC ndi yosavuta kugwiritsa ntchito, ndipo ngati zinthu zoyeretsera ziwonjezedwa panthawi yopanga, zidzakhudza ubwino wake. Komabe, zinthu zambiri zabwino zimakhala ndi kuyera bwino. (2) Kuyera: Kuyera kwa HPMC nthawi zambiri kumakhala ndi maukonde 80 ndi maukonde 100, ndipo maukonde 120 ndi ochepa. HPMC yambiri yopangidwa ku Hebei ndi maukonde 80. Kuyera bwino, nthawi zambiri, kumakhala bwino. (3) Kutumiza kuwala: ikani hydroxypropyl methylcellulose (HPMC) m'madzi kuti ipange colloid yowonekera, ndikuyang'ana momwe kuwala kumayendera. Kutumiza kuwala kwakukulu, kumakhala bwino, zomwe zikusonyeza kuti mulibe zinthu zochepa zosungunuka. . Kulowa kwa ma reactor olunjika nthawi zambiri kumakhala bwino, ndipo kwa ma reactor opingasa kumakhala koipa, koma sizikutanthauza kuti mtundu wa ma reactor olunjika ndi wabwino kuposa wa ma reactor opingasa, ndipo mtundu wa chinthu umatsimikiziridwa ndi zinthu zambiri. (4) Mphamvu yeniyeni: Mphamvu yeniyeni ikakula, kulemera kwake kumakhala bwino. Kuchuluka kwake ndi kwakukulu, makamaka chifukwa chakuti kuchuluka kwa hydroxypropyl group mkati mwake kuli kokwera, ndipo kuchuluka kwa hydroxypropyl group kuli kokwera, kusunga madzi kumakhala bwino. (5) Kuwotcha: Tengani gawo laling'ono la chitsanzocho ndikuliyatsa ndi moto, ndipo zotsalira zoyera zimakhala phulusa. Zinthu zoyera kwambiri, khalidwe lake limakhala loipa kwambiri, ndipo palibe zotsalira zilizonse muzinthu zoyera.

Kodi mtengo wa hydroxypropyl methylcellulose ndi wotani?

—–Yankho; mtengo wa hydroxypropylmethyl umadalira kuyera kwake ndi kuchuluka kwa phulusa. Kuyera kwake kukakhala kwakukulu, kuchuluka kwa phulusa kumakhala kochepa, mtengo wake umakwera. Kupanda kutero, kuyera kwake kukakhala kochepa, kuchuluka kwa phulusa kumakhala kochepa, mtengo wake umachepa. Ton kufika pa 17,000 yuan pa tani. 17,000 yuan ndi chinthu choyera chomwe chilibe zodetsa zilizonse. Ngati mtengo wa unit uli wapamwamba kuposa 17,000 yuan, phindu la wopanga lawonjezeka. N'zosavuta kuona ngati khalidwe lake ndi labwino kapena loipa malinga ndi kuchuluka kwa phulusa mu hydroxypropyl methylcellulose.

Kodi kukhuthala kotani kwa hydroxypropyl methylcellulose komwe kuli koyenera kugwiritsa ntchito ufa wa putty ndi matope?

—–Yankho; ufa wa putty nthawi zambiri umakhala wa yuan 100,000, ndipo kufunikira kwa matope ndi kwakukulu, ndipo umafunika yuan 150,000 kuti ukhale wosavuta kugwiritsa ntchito. Komanso, ntchito yofunika kwambiri yahydroxypropyl methylcellulosendi kusunga madzi, kutsatiridwa ndi kukhuthala. Mu ufa wa putty, bola ngati kusunga madzi kuli bwino ndipo kukhuthala kuli kochepa (70,000-80,000), n'zothekanso. Zachidziwikire, kukhuthala komwe kuli pansi pa 100,000 kumakhala kokwera, ndipo kusunga madzi kumakhala bwino. Kukhuthala komwe kuli pamwamba pa 100,000, kukhuthala kumakhudza kusunga madzi. Kukhudzika sikuli kwakukulu.
