HPMC ee Dhismaha

Hydroxypropyl methyl cellulose HPMC waa maaddo polymer dabiici ah cellulose sida walxo ceeriin ah, iyada oo loo marayo taxane ah oo farsamaynta kiimikada oo ka samaysan eter cellulose non-ion. Waa budo cad oo aan ur lahayn, dhadhamin, aan sun ahayn oo ku fidaysa xal kolloid oo cad ama waxoogaa daruuro leh oo biyo qabow ah. Iyada oo dhumucdiisuna, adhesion, kala firidhsan, emulsification, formation film, ganaax, adsorption, jel, hawlaha dusha, haynta qoyaan iyo ilaalinta kolloidal, iwm. warshadaha dhoobada, daawooyinka, cuntada, dunta, beeraha, kiimikooyinka maalinlaha ah iyo warshado kale.

Isla'egta kiimikada:
[C6H7O2(OH) 3-MN (OCH3) M (OCH2CH(OH)CH3) N] X

Guryaha HPMC ee loo isticmaalo Dhismaha
1. Haysashada biyaha
Hydroxypropyl methyl cellulose HPMC ee dhismaha waxay ka hortagtaa nuugista xad-dhaafka ah ee biyaha by substrate-ka, iyo biyaha waa in lagu hayaa malaasada inta ugu badan ee suurtogalka ah inta lagu jiro dhamaystirka adkaynta gypsum. Hantidan waxaa loo yaqaanaa haynta biyaha, waxayna u dhigantaa duleelka dhismaha gaarka ah ee hydroxypropyl methyl cellulose xal HPMC ee ku jira stucco, marba marka ka dambaysa mawjadaha xalka, ayaa sare u kaca awoodda haynta biyaha.
Sida ugu dhakhsaha badan content biyaha la kordhiyo, awoodda haynta biyaha waa la dhimay, sababtoo ah biyaha kordhay qaseen dhismaha hydroxypropyl methyl cellulose xal HPMC, taasoo keentay in hoos u viscosity.
2. Sag iska caabin ah
stucco oo u adkaysata qulqulka iyo laadlaadda waxay u ogolaataa wax-dhisuhu inuu maro dahaar dhumuc weyn leh iyada oo aan socodka tooska ah lahayn, taas oo sidoo kale ka dhigan in stucco lafteedu ay tahay thixotropic, haddii kale waxay hoos u sii socotaa inta lagu jiro dhismaha.
3. Yaree viscosity, dhismo fudud
Marka lagu daro noocyo kala duwan oo dhismo gaar ah hydroxypropyl methyl cellulose HPMC, viscosity hoose iyo dhismo fudud waxaa laga heli karaa malaasta gypsum ah, iyadoo la isticmaalayo heerka viscosity hoose dhismo u go'ay hydroxypropyl methyl cellulose HPMC, maw ilaa xad iyo dhismo fudud, si kastaba ha ahaatee, dhismaha viscosity hoose u go'ay. hydroxypropyl methyl cellulose HPMC awoodda haynta biyaha waa daciif, waxay u baahan tahay in la kordhiyo qadarka lagu daray.
4. Heerka kobaca awoodda ee stucco
Qadar go'an oo hoobiye qalalan, waa dhaqaale badan si loo soo saaro mugga hoobiyeyaasha qoyan ee sarreeya, kaas oo lagu gaari karo in lagu daro biyo badan iyo goobooyin. Laakiin biyaha badan iyo goobooyinku waxay dhaawici karaan xoogga.

10.hoobiye premixed
haynta biyaha hoobiye ee premixed waxay ka fiican tahay alaabta caadiga ah, si loo hubiyo fuuqbaxa buuxa ee alaabta simentitiga ah, si weyn uga hortagto qalajinta degdega ah ee ay keento xoogga curaarta oo yaraada, iyo qallajinta yaraanshaha ay keento dildilaaca. HPMC waxa kale oo ay leedahay saamayn entraining hawada gaar ah, hoobiye premixed gaar ah HPMC, hawo entraining qadarka saxda ah, labis iyo goobooyin yar yar, hagaajin karaa xoogga iyo gloss ee hoobiye premixed. Hoobiyeyaasha premixed ee gaarka ah ee HPMC waxay leeyihiin saamayn gaabis gaar ah, waxay dheerayn kartaa wakhtiga furitaanka hoobiye premixed, yaraynta dhibka dhismaha.
