Kugwiritsa ntchito ndi kusamala kwa hydroxypropyl methylcellulose

1. Mawu oyamba a hydroxypropyl methylcellulose

Hydroxypropyl methylcellulose (HPMC)ndi non-ionic cellulose ether kwambiri ntchito yomanga, mankhwala, chakudya, zodzoladzola ndi minda ina mafakitale. Lili ndi kukhuthala kwabwino, kupanga mafilimu, kusunga madzi, kugwirizanitsa, mafuta odzola ndi emulsifying katundu, ndipo amatha kusungunuka m'madzi kuti apange njira yowonekera kapena yozungulira ya colloidal.

2. Ntchito zazikulu za hydroxypropyl methylcellulose

Makampani omanga

Tondo la simenti: lomwe limagwiritsidwa ntchito kupititsa patsogolo ntchito yomanga, kukonza kusungirako madzi ndi kumamatira, kupewa kusweka, komanso kulimbitsa mphamvu.

Putty ufa ndi zokutira: kupititsa patsogolo ntchito yomanga, kukonza kusunga madzi, kupewa kusweka ndi ufa.

Zomatira pa matailosi: onjezerani mphamvu zomangira, kusunga madzi komanso kusavuta kumanga.

Mtondo wodziyimira pawokha: sinthani madzimadzi, pewani delamination ndikuwonjezera mphamvu.

Zogulitsa za Gypsum: kuwongolera magwiridwe antchito, kuwongolera kumamatira ndi mphamvu.

Makampani opanga mankhwala

Monga chithandizo chamankhwala, chitha kugwiritsidwa ntchito ngati thickener, stabilizer, emulsifier, filimu yakale komanso yotulutsa nthawi zonse.

Amagwiritsidwa ntchito ngati disintegrant, zomatira ndi zokutira pakupanga piritsi.

Ili ndi biocompatibility yabwino ndipo imagwiritsidwa ntchito kwambiri pokonzekera maso, makapisozi ndi kukonzekera kumasulidwa kosalekeza.

Makampani opanga zakudya

Monga chowonjezera cha chakudya, chimagwiritsidwa ntchito makamaka ngati thickener, emulsifier, stabilizer ndi film-forming agent.

Ndizoyenera kupanikizana, zakumwa, ayisikilimu, zophikidwa, ndi zina zotero, kuti zikhwime ndi kukonza kukoma.

Zodzoladzola ndi zinthu zosamalira munthu

Amagwiritsidwa ntchito ngati thickener ndi emulsifier, omwe amagwiritsidwa ntchito kwambiri pazosamalira khungu, shampu, mankhwala otsukira mano, etc.

Lili ndi zinthu zabwino zopatsa mphamvu komanso zokhazikika, zomwe zimakulitsa luso lazogwiritsidwa ntchito.

Ntchito zina zamakampani

Amagwiritsidwa ntchito ngati thickener, zomatira kapena emulsifier mu ceramics, nsalu, papermaking, inki, mankhwala ndi mafakitale ena.

3. Njira yogwiritsira ntchito

Disolution njira

Njira yobalalitsira madzi ozizira: Iwaza pang'onopang'ono HPMC m'madzi ozizira, yambitsani mosalekeza mpaka omwazika, kenako kutentha mpaka 30-60 ℃ ndikusungunula kwathunthu.

Njira yosungunula madzi otentha: choyamba nyowetsani HPMC ndi madzi otentha (oposa 60 ° C) kuti ifufuze, kenaka yikani madzi ozizira ndikugwedeza kuti asungunuke.

Njira yosakaniza yowuma: choyamba sakanizani HPMC ndi ufa wina wowuma, kenaka yikani madzi ndikuyambitsa kuti musungunuke.

Ndalama zowonjezera

M'makampani omanga, kuchuluka kwa HPMC nthawi zambiri kumakhala 0.1% -0.5%.

M'makampani azakudya ndi mankhwala, kuchuluka kwake kumasinthidwa malinga ndi cholinga chenichenicho.

4. Njira zopewera kugwiritsa ntchito

Zosungirako

Sungani pamalo ozizira, owuma, ndi mpweya wabwino, pewani chinyezi ndi kuwala kwa dzuwa.

Khalani kutali ndi magwero a kutentha, magwero a moto ndi ma oxidants amphamvu kuti mupewe kuwonongeka ndi kuyaka.

Njira zodzitetezera pakuyimitsa

Pewani kuwonjezera kuchuluka kwa HPMC nthawi imodzi kuti muteteze mapangidwe a zotupa komanso kukhudza kuwonongeka.

Liwiro losungunuka limakhala lochedwa m'malo otentha otsika, ndipo kutentha kumatha kuonjezedwa moyenerera kapena nthawi yosonkhezera ikhoza kuonjezedwa.

Chitetezo chogwiritsa ntchito

HPMC ndi chinthu chopanda poizoni komanso chosavulaza, koma chingayambitse kupsa mtima kwa mpweya mu fumbi la ufa, ndipo fumbi lalikulu liyenera kupeŵa.

Ndi bwino kuvala chigoba ndi magalasi pa ntchito yomanga kupewa fumbi mkwiyo kwa kupuma thirakiti ndi maso.

Kugwirizana

Mukamagwiritsa ntchito, samalani kuyanjana ndi mankhwala ena, makamaka pokonzekera zida zomangira kapena mankhwala, kuyezetsa koyenera kumafunika.

Pankhani ya chakudya ndi mankhwala, malamulo oyenera ndi miyezo iyenera kukwaniritsidwa kuti zitsimikizire chitetezo.

Hydroxypropyl methylcelluloseamagwiritsidwa ntchito kwambiri m'mafakitale ambiri chifukwa cha ntchito zake zabwino kwambiri. Mukamagwiritsa ntchito, ndikofunikira kudziwa njira yoyenera yosungunulira ndi luso logwiritsa ntchito, ndikulabadira nkhani zosungirako ndi chitetezo kuti zitsimikizire kukhazikika ndi magwiridwe antchito a chinthucho. Kugwiritsa ntchito bwino kwa HPMC sikungowonjezera ubwino wa mankhwala, komanso kupititsa patsogolo luso la zomangamanga ndi kupanga.
