Kodi ndimavuto ati a hydroxypypyl methylcellulose?

1. Kodi ndi chiyani chofunikira kwambiri cha hydroxypropyl methylcellulose (hpmc)?

Hydroxypypyl amagwiritsidwa ntchito kwambiri popanga zinthu zomanga, zokongoletsa, mateloti, mankhwala, maluwa, mafakitale, odzola, fodya komanso mafakitale ena. Hydroxypropyll methylcelulose imatha kugawidwa mu kalasi yomanga, chakudya kalasi yam'madzi molingana ndi pulogalamu yake. Pakadali pano, ambiri mwazinthu zapakhomo ndi kalasi yomanga. Mu kalasi yomanga, putty ufa umagwiritsidwa ntchito pamlingo waukulu, pafupifupi 90% amagwiritsidwa ntchito ngati ufa wa putty, ndipo ena onse amagwiritsidwa ntchito matope a simenti ndi guluu.

2. Pali mitundu ingapo ya hydroxypropyl methylcellulose (hpmc), ndipo kusiyana kotani pakugwiritsa ntchito kwawo?

HPMC ikhoza kugawidwa mu mtundu wa anthu wamba komanso wotentha. Malonda a mtundu wa nthawi yomweyo amabalalitsa msanga akakumana ndi madzi ozizira ndikuzimiririka m'madzi. Pakadali pano, madziwo alibe mafakisoni chifukwa HPMC imangomwazika m'madzi popanda kusinthika kwenikweni. Patatha pafupifupi mphindi ziwiri, mafayilo amadzimadzi pang'onopang'ono amawonjezeka, ndikupanga mafilimu owonekera. Zogulitsa zosungunuka, zikakumana ndi madzi ozizira, zimatha kufalitsa msanga m'madzi otentha ndikuzimiririka m'madzi otentha. Kutentha kukagwa mpaka kutentha kwinakwake, mafayilo amawoneka pang'onopang'ono mpaka apangire cololous wowonekera. Mtundu wosungunuka umatha kugwiritsidwa ntchito mu ufa ndi matope. M'dothi wamadzimadzi ndi utoto, padzakhala gulu lazinthu zomwe sizingagwiritsidwe ntchito. Mtundu wa nthawi yomweyo umakhala ndi ntchito zambiri. Itha kugwiritsidwa ntchito mu ufa ndi matope, komanso guluu wamadzimalo ndi utoto, popanda contacation.

3. Kodi kusintha kwa ma hydroxypypyll methylcelulose (hpmc)?

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

1) Ikani madzi okwanira mu chidebecho ndikutenthe mpaka 70 ° C. The hydroxypropyl pang'onopang'ono idawonjezeredwa pang'onopang'ono poyambitsa pang'onopang'ono, poyamba HPMC idayandama m'madzi, kenako pang'onopang'ono adapanga malo ocheperako, omwe adakhazikika pansi pa kusungunuka.

2) Onjezani 1/3 kapena 2/3 mwa madzi ofunikira mu chidebe, ndikutenthetsa mpaka 70 ° C, malinga ndi njira ya 1), kufalitsa hpmc kuphika madzi otentha; Kenako onjezani kuchuluka kwa madzi ozizira kumadzi otentha, osakaniza adazimitsidwa pambuyo poyambitsa.

Njira yosakanikirana: Sakanizani ufa wa hpmc wokhala ndi zinthu zina zambiri za ufa, kusakaniza bwino ndi chosakanizika, kenako ndikungowonjezera ufa uliwonse wamakona, ndikusungunuka nthawi yomweyo mukakumana ndi madzi. Ufa ndi opanga matope akugwiritsa ntchito njirayi. [Hydroxypropyl methylcellulose (hpmc) imagwiritsidwa ntchito ngati thickener ndi wogulitsa madzi mu matope a ufa.]

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

. Komabe, ambiri mwazinthu zabwino zimakhala ndi kuyera kwabwino.

. Omaliza chabwino, nthawi zambiri, zabwinoko.

. Kuchuluka kwake, kukhala bwinoko, komwe kumawonetsa kuti kulibe kotheka mu izo. Kufalikira kwa vatirs nthawi zambiri kumakhala kwabwino, ndipo chifukwa cha zopingasa ndizoyipa, koma sizitanthauza kuti mawonekedwe ofukula ofukula ndi abwino kuposa omwe ali ndi zinthu zambiri zimatsimikiziridwa ndi zinthu zambiri.

(4) Mphamvu yokoka: mphamvu yayikulu, yolemera. Kutanthauzira kwake ndi kwakukulu, nthawi zambiri chifukwa cha gulu la hydroxypropyl mkati mwake ndi lalitali, ndipo zomwe zili ndi hydroxypyl gululi ndizokwera, kusungidwa kwamadzi ndikwabwino.

5. Kodi kuchuluka kwa hydroxypropyll methylcelulose (hpmc) mu ufa wanji?

Kuchuluka kwa HPMC yomwe imagwiritsidwa ntchito pamapulogalamu othandiza kumasiyananso malinga ndi nyengo, kutentha, mtundu wa phulusa lakumaloko, njira yofayo ndi "yabwino yofunikira makasitomala". Nthawi zambiri, pakati pa 4 kg ndi 5 kg. Mwachitsanzo: ambiri a ufa ku Beijing ndi 5 kg; Ambiri mwa ufa wa putty mu guizhou ndi 5 makilogalamu m'chilimwe ndi 4.5 makilogalamu nthawi yozizira; Kuchuluka kwa ufa wa punty ku Yunnan kuli kochepa, nthawi zambiri makilogalamu 3 kg, etc.

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

Mafuta a putty amakhala okwanira kwa 100,000 Yuan, ndipo zofuna za matope ndizokwera, ndipo 150,000 yun ndiyofunikira kuti igwiritse ntchito mosavuta. Kuphatikiza apo, ntchito yofunika kwambiri ya HPMC ndi kusungidwa kwamadzi, kenako ndikukula. Mu ufa wa putty, bola ngati kusungidwa kwamadzi ndikwabwino ndipo mafayilo ali otsika (70,000-80,000), nkothekanso. Inde, mafakiti apamwamba, abwinobwino achibale. Maonekedwe oposa 100,000, chidwi cha ma visc chimakhudza kusungidwa kwamadzi. Osatinso.

7. Kodi ndi zisonyezo zazikulu zaukadaulo za hydroxypypyl methylcelulose (hpmc)?

Hydroxypyl ndi mafakisoni, ogwiritsa ntchito ambiri amadera nkhawa za zizindikiro ziwiri izi. Omwe ali ndi hydroxypropyl omwe amakhala ndi kusungidwa kwa madzi. Yemwe ali ndi ufa wambiri ali ndi kusungidwa kwabwino kwamadzi, koma (osati mwamtheradi), ndipo amene ali ndi mawonekedwe apamwamba amagwiritsidwa ntchito bwino matope a simenti.

8. Kodi zida zazikulu za hydroxypypyl ndi methylcelulose (hpmc)?

Zopangira zazikuluzikulu za hydroxypylropyl methylcellulose (HPMC): Makina oyenga, andyl chloride, ma propropanol, isoppanol, eyporpanol, eyporpanol, esuppanol, eyponol, esuppanol, eyporopanol, esuppanol, eyOP.

9. Kodi ntchito yayikulu ndi iti yomwe imagwiritsidwa ntchito kwa HPMC mu ufa wa punty, ndipo zimachitika?

Mu ufa wa putty, HPMC imasewera maudindo atatu a kukula, kusungidwa kwamadzi ndikumanga. Kukula: cellose imatha kukwiya kuyimitsa ndikusunga yunifolomu ndikutsika, ndikupewa kusamba. Kusungidwa kwamadzi: Pangani utoto wa putty pang'onopang'ono, ndikuthandizira calcium kuti muchitepo kanthu pansi pamadzi. Ntchito Yomanga: Cellulose ili ndi mafuta owuma, omwe amatha kupangitsa kuti ufa ukhale ndi zomangamanga. HPMC sitenga nawo mbali pamavuto aliwonse, koma imangochita ntchito yothandiza. Kuonjezera madzi ku ufa wa putty ndikuyika pakhoma ndikuchitika kwa mankhwala, chifukwa zinthu zatsopano zimapangidwa. Ngati muchotsa ufa wa pakhoma kuchokera kukhoma, ndikupukuta ufa, ndikuigwiritsanso ntchito, sizigwira ntchito chifukwa zinthu zatsopano (calcium carbonate).) Zigawo zikuluzikulu za Ash calcium ufa ndi: osakaniza a ca (oh) 2, ca (o) 2: munjira iliyonse.

M'malingaliro a Sing'anga, osakhala a Ions ndi zinthu zomwe sizimayenda m'madzi. Ma Ionirization amatanthauza njira yomwe electrolyte imasungunuka mu ma masikono omwe amatha kusunthira momasuka mu zosungunulira zina (monga madzi, mowa). Mwachitsanzo, sodium chloride (nacl), mchere womwe timadya tsiku lililonse, umasungunuka m'madzi ndi inozi kuti apange ma ionsuum osinthika komanso oyenda. Ndiye kuti, pamene HPMC imayikidwa m'madzi, sizingasungunuke mu ma ions, koma kukhalapo mawonekedwe a mamolekyulu.
