CAS: 9004-65-3
Hydroxypropyl Methyl Cellulose (HPMC) waxaa sidoo kale loo yaqaan MHPC, waa noocyada aan-ionic cellulose ether, kuwaas oo ah budo ka mid ah caddaan ilaa midab cad-cad, oo u shaqeeya sida dhumuc weyn, binder, filim-hore, surfactant, kolloid ilaalinta, saliidaha, emulsifier, iyo cayrinta iyo gargaarka biyaha ceyrinta. Intaa waxaa dheer, noocyadan ethers cellulose waxay muujinayaan sifooyinka gelation kulaylka, dheef-shiid kiimikaad, caabbinta enzyme, urta iyo dhadhanka hooseeya, iyo xasilloonida pH. HPMC waxaa si balaadhan loogu isticmaalaa in dhismaha,pharmaceutical, food, isqurxin, saabuunta, rinji, dunta iwm Ka dib markii wax laga beddelay, waxaan heli karnaa badeecada leh waqti dheer oo furan, ka hortag wanaagsan, karti shaqo oo wanaagsan iwm.

Codsiyada:
darbiga derbiga
- Haysashada biyaha: waxa ugu badan ee ka kooban biyaha ku jira slurry.
- Ka-hortagga-soo-baxa: marka la faafinayo jiingado jaakad dhumuc weyn leh waa laga fogaan karaa.
- Waxsoosaarka hoobiye ee kordhay: iyadoo ku xidhan miisaanka isku dhafka qalalan iyo qaabaynta habboon, HPMC waxay kordhin kartaa mugga hoobiye.
Nidaamka Dhamaystirka iyo Dahaarka Dibadda (EIFS)
- adhesion oo la hagaajiyay
- Awood qoynta wanaagsan ee guddiga EPS iyo substrate.
- Soo gelista hawada oo yaraatay iyo qaadashada biyaha.
Is-kala-qaadid
Ka-hortagga qulqulka biyaha iyo wasakhaynta walxaha.
Wax saamayn ah kuma laha dareeraha dareeraha leh ee mawgu hooseeyo
HPMC, iyadoo sifooyinkeeda xajinta biyaha ay hagaajinayaan waxqabadka dhamaadka dusha sare.
Filler dildilaaca
Shaqaynta ka sii wanaagsan: dhumucda saxda ah iyo caagagga.
Haysashada biyuhu waxay xaqiijisaa wakhtiga shaqada oo dheer.
Iska caabin sag: awoodda isku xidhka hoobiye oo la roonaaday.
Xabagta Tile
Shaqaynta ka sii wanaagsan: dufanka iyo caagagga malaasta waa la hubiyaa, hoobiye si fudud oo degdeg ah ayaa loo marsiin karaa.
Haysashada wanaagsan ee biyaha: wakhtiga furitaanka ee dheeraadka ah ayaa ka dhigi doonta tix-gelinta mid waxtar leh.
Ku dheggan oo la hagaajiyay iyo iska caabbinta silbashada: gaar ahaan foornada culus.
Hoobiye isku darka qalalan
Nafaqada qallalan ee fudud ee isku darka ah sababtoo ah milanka biyaha qabow: samaynta kuusku si fudud ayaa looga fogaan karaa, oo ku habboon foornada culus.
Haysashada wanaagsan ee biyaha: ka hortagga dareeraha dareeraha ee substrates, waxa ku habboon biyaha ku jira waxaa lagu hayaa isku dar ah taas oo dammaanad qaadaysa waqti dheer oo isku dhejin ah.
Malaasta sibidhka
Baahida biyaha oo korodhay: wakhtiga furan oo kordhay, aagga spry oo balaadhiyey iyo qaabaynta dhaqaale oo badan.
Faafinta fudud iyo iska caabbinta hoos u dhaca oo roonaaday sababtoo ah joogteynta oo soo hagaagtay.
Baakad
Alaabada HPMC waxa ay ka buuxaan saddex bac oo xaashi ah oo ay ku jirto bac polyetylen ah oo gudaha ah oo la xoojiyay, miisaanka saafiga ahi waa 25kg kiishadiba.
Kaydinta:
Ku hay bakhaar qallalan oo qabow, kana fog qoyaanka, qorraxda, dabka, roobka.
