Kutanthauzira kwa hydroxypropyl methylcellulose mavuto a HPMC

1. Pali mitundu ingapo ya hydroxypypyl methylcellulose hpmc, ndipo pali kusiyana kotani pakati pa kugwiritsa ntchito kwawo?

Yankho: Hydroxypypyl methylcellulose hpmc imatha kugawidwa mu mtundu wa nthawi yomweyo komanso mtundu wosungunuka. Zogulitsa zomwe zimabalalika mwachangu m'madzi ozizira ndikuzimiririka m'madzi. Pakadali pano, madziwo alibe mamasukidwe, chifukwa HPMC imangomwazika m'madzi, palibe sungunula kwenikweni. Patatha pafupifupi mphindi ziwiri, mawike amadzimadzi pang'onopang'ono adakwera pang'onopang'ono, ndikupanga mafilimu owonekera. Zogulitsa zotentha, mukakumana ndi madzi ozizira, zimatha kufalikira msanga m'madzi otentha ndikuzimiririka m'madzi otentha. Kutentha pakagwa mpaka kutentha kwinakwake, ma viwawo amawoneka pang'onopang'ono mpaka Collous yowonekera bwino imapangidwa. Mtundu wosungunuka umatha kugwiritsidwa ntchito mu ufa ndi matope. M'magulu a udzu ndi utoto, chopindika chodabwitsa chidzachitika ndipo sichingagwiritsidwe ntchito. Mtundu wa nthawi yomweyo umakhala ndi ntchito zambiri. Itha kugwiritsidwa ntchito mu ufa ndi matope, komanso matalala okwanira komanso utoto, popanda contacation.

2. Kodi cholinga chachikulu cha hydroxypypyl noth methylcelulose (hpmc) ndi chiani)?

Yankho: HPMC imagwiritsidwa ntchito kwambiri pazomangira, zokutira, matekenti, matenti, mankhwala, chakudya, maluwa, odzola, fodya komanso mafakitale ena. HPMC ikhoza kugawidwa mu: Grace Womanga, kalasi ya chakudya ndi kalasi ya mankhwala molingana ndi cholinga. Pakadali pano, ambiri mwazinthu zapakhomo ndi kalasi yomanga. Mu kalasi yomanga, kuchuluka kwa ufa wa putty ndi waukulu kwambiri, pafupifupi 90% amagwiritsidwa ntchito pavety ufa, ndipo ena onse amagwiritsidwa ntchito matope a simenti ndi gulu.

3. Kodi njira zosungunuka za hydroxypypyl ndi methylcellulose hpmc?

Yankho: Njira yotentha yamadzi: Popeza HPMC sinasungunuke m'madzi otentha, hpmc imatha kukhala yobalalika m'madzi otentha nthawi yoyamba, kenako kusungunuka mwachangu mukakhazikika. Njira ziwiri zomwe zafotokozedwa motere:

1). Kenako onjezani kuchuluka kwa madzi ozizira kumadzi otentha mu slurry, osakaniza adakhazikika pambuyo poyambitsa.

Njira yosakanikirana: Sakanizani ufa wa hpmc wokhala ndi zinthu zina zambiri za ufa, kusakaniza bwino ndi chosakanizira, kenako kuwonjezera madzi nthawi ino popanda kutsekera pang'ono. Ufa udzasungunuka nthawi yomweyo. Njira ya --this imagwiritsidwa ntchito ndi ufa ndi opanga matope. [Hydroxypropyl methylcellulose (hpmc) imagwiritsidwa ntchito ngati Thicner ndi Wothandizira madzi mu matope a ufa.

2), ikani madzi otentha mu chidebe, ndikutenthetsa pafupifupi 70 ℃. The hydroxypropyl pang'onopang'ono idawonjezeredwa pang'onopang'ono poyambitsa pang'onopang'ono, poyamba HPMC idayandama m'madzi, kenako pang'onopang'ono adapanga malo osalala, omwe adakhazikika ndi osokoneza.

4. Momwe mungawonetsere mtundu wa hydroxypropyl methylcellulose (hpmc) mongoyerekeza komanso moyenera.

Yankho: (1) Mphamvu yokoka: yayikulu kwambiri mphamvu, yolemera. zazikulu, nthawi zambiri chifukwa

. Komabe, ambiri mwazinthu zabwino zimakhala ndi kuyera kwabwino.

. Ambiri mwa HPMC yomwe imapangidwa mu hebei ndi 80 mesh. Makina abwino, abwino kwambiri.

. Kuchuluka kwake, kukhala zabwinoko, zomwe zikuwonetsa kuti pali zinthu zochepa zokhutitsidwa. Kufalikira kwa vatirs nthawi zambiri kumakhala kwabwino, ndipo chifukwa cha zolimbitsa thupi ndizoyipa, koma sizinganenedwe kuti mtundu wa zolimba umakhala bwino kuposa zomwe zimapangitsa kuti zinthu ziyende bwino. The hydroxypropyl zomwe zili mkati mwake zimakhala zazitali, ndipo hydroxypropyl ndizokwera, kusungira madzi ndikwabwino.

5. Kodi ndi zisonyezo zazikulu zaukadaulo za hydroxypypyl no methylcelulose (hpmc)?

Yankho: Hydroxypropyl ndi mafakisoni, ogwiritsa ntchito ambiri amasamala za zizindikiro ziwiri izi. Zokwera kwambiri hydroxypyl, kukonzanso kwamadzi. Mawonekedwe, okhala ndi madzi, komanso (mmalo mwa

6. Kodi mawu oyenera a hydroxypropyll methylcelulose (hpmc) ndi chiyani?

Yankho: Mafuta a putty nthawi zambiri, Yuan, ndipo matope akufunika kwambiri, ndipo ndikosavuta kugwiritsa ntchito pa 150,000 juan. Kuphatikiza apo, gawo lofunikira kwambiri la hpmc ndikusunga madzi, kenako ndikukula. Mu ufa wa putty, bola ngati kusunga kwamadzi ndikwabwino ndipo mamasuwa ndi otsika (70,000-80,000), nkothekanso. Zachidziwikire, ngati mafanowo ndi okwera, kusungidwa kwamadzi kumakhala bwino. Maonekedwe oposa 100,000, mphamvu zakusintha pamadzi osasungidwa sizambiri. Mwamtheradi) zilinso bwino, ndipo maonedwewo ndi okwera, ndipo ndibwino kugwiritsa ntchito matope a simenti.

7. Kodi zida zazikulu za hydroxypypyl ndi methylcellulose (hpmc)?

Yankho: Zida zazikuluzikulu za hydroxypypyl methylcellulose (HPMC): Zipangizo zoyamwa, acipyl, tulporpanol, endopropanol, eyporpanol, eyporpanol, esuppanol, esuppanol, eyporpanol, eyporpanol, eyporpanol, eyporpanol, eyporpanol, eyporpanol, eyporpanol, eyporpanol, eyporpanol, eyponol, esuppanol, esuppanol.
