Hydroxypypyl methyl cellulose ether (hpmc)

Mawonekedwe:
Monga kusungidwa kwamadzi, kukulira madzi, rheology ndi kutsatira, ndiye chinthu choyambirira chosintha matongosolo ndi zokongoletsera.
Zogwiritsa ntchito zosiyanasiyana: Chifukwa cha magiredi athunthu, zitha kugwiritsidwa ntchito pazomangira zonse zomangira. 
Mlingo wa ③small: 2-3 makilogalamu pa mainchesi omanga ufa chifukwa cha mtundu wambiri.
④ Kulimbana ndi kutentha kwambiri: Kusunga kwamadzi kwa zinthu zonse za HPMC kudzachepa ndi kuchuluka kwa kutentha. Mosiyana ndi zimenezo, zinthu zathu zimatha kupangitsa matope kukhala ndi madzi osungirako madzi pomwe kutentha kumafika 30-40 ° C. Kusunga kwamadzi kokhazikika ngakhale kutentha kwambiri kwa maola 48.
Kusungunuka kwa ⑤good: Akatenthe kutentha, onjezani madzi ndikuyambitsa kwa mphindi pafupifupi 5, zilekeni kwa mphindi zochepa, kenako ndikuyambitsa kusungunula. Kusungunuka kumathandizira pa PH8-10. Njira yothetsera vutoli imayikidwa kwa nthawi yayitali ndipo imakhala ndi bata wabwino. Mu zouma zosakanikirana, liwiro lobalalitsa ndikusungunuka m'madzi ndizabwino kwambiri.

Udindo wa HPMC mu matope a ufa

Mu matope a ufa wa ufa, methyl cellulose eber amatenga gawo la kusungidwa kwamadzi, kukulitsa ndi kukonza magwiridwe antchito. Zochita zabwino zamadzi zimatsimikizira kuti matope sadzayambitsa misampha, utsi ndi kuchepetsa mphamvu chifukwa cha kuchepa kwa madzi komanso simenti yokwanira ya simenti; Kukula kwa kukula kumathandizira kwambiri kulimba kwa matope onyowa, ndipo kuwonjezera kwa methyl cellulose ether ethel ethel ethel ether ether ether ether ether ether ether ether etherc yonyowa matope onyowa pakhoma ndikuchepetsa zinyalala.

Nthawi zambiri, mafakiti apamwamba, abwinobwino amadzisungira madzi. Komabe, mafayilo apamwamba kwambiri, olemera kwambiri a MC, ndipo kusungunuka kwake kumachepa, zomwe zimatha kuwononga mphamvu ndi matope omanga matope. Maonekedwe ake, zoonekeratu kuti zimakula kwambiri patavala matope, koma siyofanana mwachindunji. Matope apamwamba, matope owoneka bwino adzakhala. Panthawi yomanga, imawonekera ngati imamatira ku starpiper ndi kutsatira kwambiri mpaka gawo lapansi. Koma sizothandiza kukulitsa mphamvu ya matonthozo onyowa.

Mankhwala ndi mankhwala:

1. Maonekedwe: oyera kapena oyera-oyera.
2. Kukula kwa tinthu: 80-100 mesh Pass kuli koposa 98,5%; Mlingo wa Mesh Unge ndi 100%.
3. Kutentha kwa kada: 280-300 ° C
4.
5. Kutentha kosiyanitsa: 190-200 ° C.
6. Matendawa: 2% am'madzi am'madzi ndi 42-56dy / cm3.
7. Zosungunulira m'madzi ndi zina zosungunulira, monga ethanol / madzi, prosenol / madzi, Trichlorororoeane, motero ndi magawo oyenera. Mayankho am'madzi ali pansi. Kuwonekera kwambiri komanso kusisita. Makonda osiyanasiyana a zinthu amakhala ndi kutentha kosiyanasiyana, ndipo solubilimen imasintha ndi mafayilo. Kutsitsa mamasukidwe, chachikulucho chosungunuka. Maupangiri osiyanasiyana a hpmc amakhala ndi kusiyana kwina, ndipo kuwonongeka kwa HPMC m'madzi sikukhudzidwa ndi mtengo wa pH.

Cholinga chachikulu:

1. Makampani omanga: Monga wothandizirana ndi madzi ndikuyika matope a simenti, amatha kupanga matope. Wogwiritsidwa ntchito ngati chomangira mu pulasitala, pulasitala, putty ufa kapena zinthu zina zomanga kuti zikuwonjezereka komanso nthawi yayitali. Itha kugwiritsidwa ntchito ngati matayala a phala, zokongoletsa pulasitiki, zokongoletsera pulasitiki, zimapangitsanso kuchepetsa kuchuluka kwa simenti. Kugwirira ntchito kwa madzi osungidwa kwa HPMC kumalepheretsa kugona chifukwa chopukutira chifukwa choyanika mwachangu atatha kugwiritsa ntchito, ndikuwonjezera mphamvu pambuyo polimbana.
2. Makampani opanga za ceramic: Amagwiritsidwa ntchito kwambiri ngati ngongole popanga zinthu za ceramic.
3. Makampani okutira: Amagwiritsidwa ntchito ngati thicker, wobayira komanso kukhazikika pamakampani okutira, ndipo ali ndi kuthekera bwino m'madzi kapena okhazikika. Itha kugwiritsidwa ntchito potsegula utoto.
4. Makina osindikiza: Amagwiritsidwa ntchito ngati thicker, wobayira komanso kukhazikika m'makampani a inki, ndipo ali ndi kuthekera bwino m'madzi kapena okhazikika.
5. Pulasitini: Zogwiritsidwa ntchito ngati mawonekedwe omasulira, sofener, mafuta, etc.
6. Polyvinyl chloride: Amagwiritsidwa ntchito ngati wobalalitsa polyvinyl chloride, ndipo ndiye wamkulu wothandizira wothandizira pokonzekera pvc poyimitsidwa.
7. Ena: Chomera ichi chimagwiritsidwanso ntchito kwambiri m'chikopa, pepala, zipatso komanso zamasamba komanso mafakitale.

Momwe Mungasungunuke ndi Kugwiritsa Ntchito:

1. Tengani 1/3 kapena 2/3 mwa madzi otentha ndikuwotcha pamwamba pa 85 ° C, onjezani madzi ozizira, osakanikirana ndi osakaniza.
2. Pangani ma porridge-midrid-mowa mowa: Choyamba pangani zakumwa zoledzera za HPMC zomwe zili ndi kuchuluka kwakukulu (njira ndi yofanana ndi pamwambapa), onjezani madzi ozizira ndikupitiliza kusunthika mpaka kuwonekera.
3. Ntchito yowuma: Chifukwa chogwirizana kwambiri kwa HPMC, imatha kusakanizidwa mosavuta ndi simenti, ufa wa gypsum, utoto ndi mafilimu, ndi zina zotere, ndikukwaniritsa zomwe mukufuna.

Kusunga, Kusungira ndi Kupitirira Kusamala:

Zoyikidwa mu pulasitiki kapena mapepala okhala ndi makatoni omwe amapezeka ndi matumba a polyethylene, kulemera kwa thumba: 25kg. Osindikizidwa kuti asungidwe. Tetezani ku dzuwa, mvula ndi chinyezi nthawi yosungira ndi mayendedwe.
