Wararka Warshadaha

Jeexitaanka gidaarkawaxay ka dhigi doontaa dusha derbiga mid aan fiicneyn oo qallafsan taabashada, si fudud u wasakhaysan boodhka, saameynaya guud ahaan saameynta qurxinta. Intaa waxaa dheer, xuubka xuubka gidaarka wuxuu u horseedi doonaa daciifinta adhesion ee u dhexeeya lakabka putty iyo substrate derbiga, kaas oo u nugul inuu dhaco, sidaas darteed saameynaya flatness iyo tayada guud ee dusha derbiga. Dhacdadan waxaa inta badan sababa todobo sababood oo muhiim ah:tayada buuxinta,dheelitir la'aanta saamiga caanaha,la'aanta lagama maarmaanka ah[...]

Dhismaha casriga ah, raadinta adkeysiga, dabacsanaanta, iyo joogteynta ayaa horseeday qaadashada alaabta horumarsan.Budada polymer dib loo cusboonaysiin karo (RDP)waxa uu safka hore kaga jiraa horumarkan, isaga oo wax ka beddelaya habab-dhaqameedka sibidhka ku salaysan. Sida qayb muhiim ah oo ka mid ah hoobiyeyaasha waxqabadka sare leh,RDPwaxay xoojisaa adhesion, waterproofing, and adhesion properties, taasoo ka dhigaysa mid aan looga maarmin [...]

HPMC waxa ay ka ciyaartaa door aan la bedeli karin sida wax lagu daro oo muhiim ah samaynta xabagta tile. Budada cad ee caadiga ah ee u muuqata waa mid ka mid ah walxaha asaasiga ah ee go'aamiya waxqabadka xabagta dhoobada. Warqadan, waxaan si qoto dheer uga hadli doonaa sida HPMC u wanaajiso waxqabadka xabagta tile iyo [...]

Hydroxypropyl Methyl Cellulose Ether (HPMC),Methyl Hydroxyethyl Cellulose Eter (MHEC/HEMC)iyoHydroxyethyl Cellulose Eter (HEC)waa dhammaan derivatives cellulose muhiim ah oo si ballaaran looga isticmaalo warshadaha kala duwan. Ether-yada cellulose-ka waxaa lagu helaa iyada oo loo marayo isbeddel kiimikaad ee cellulose dabiiciga ah, iyaga oo ku siinaya sifooyin gaar ah oo la kulma [...]

Hydroxypropyl Methyl Cellulose waxay saameyn gaar ah ku leedahay xoogga hoobiye sibidhka

Hydroxypropyl methyl cellulose wuxuu door muhiim ah ka ciyaara hoobiye sibidhka.

Hydroxypropyl Methyl Cellulose (HPMC) waa polymer ether-ka aan-ionic-ka ahayn ee ku salaysan cellulose, polymer dabiici ah oo laga helay suufka sifaysan.

Saamaynta budada VAE ee sifooyinka aasaasiga ah ee hoobiye aan biyuhu lahayn.

Tijaabada malaasta sibidhka waa hab tijaabo ah oo muhiim ah oo ku saabsan goobta qalabka dhismaha, inta badan loo isticmaalo in lagu qiimeeyo waxqabadka iyo tayada malaasta sibidhka.

Hydroxypropyl methylcellulose (HPMC) waa soosaar cellulose ah oo si weyn looga isticmaalo warshado kala duwan waxaana lagu yaqaanaa wax-qabadkeeda iyo xasilloonida. Si kastaba ha ahaatee, saamaynta heerkulka sare ee HPMC waa mawduuc xiiso badan sababtoo ah saamaynta ay ku yeelan karto waxqabadka iyo sifooyinka xaruntan muhiimka ah.
