Hydroxyethyl Methyl Cellulose
HydroxyethylMethylCilose(HEMC) sidoo kale waxaa loo magacaabay Methyl Hydroxyethyl Cellulose (MHEC), waawaa cadaanmethyl cellulose ether derivativesbudo, aan ur lahayn oo aan dhadhamin, milma: ku dhawaad aan lagu milmi karin biyaha kulul, acetone, ethanol, ether iyo toluene. Waxay ku milmi kartaa biyaha iyo qaar ka mid ah dareerayaasha organic, sida ethanol/biyaha, propanol/biyaha, dichloroethane, marka loo eego qiyaasta ku haboon. Xalku wuxuu leeyahay dhaqdhaqaaqa dusha sare, daahfurnaanta sare iyo waxqabadka xasilloon. Tilmaamaha kala duwan ee alaabadu waxay leeyihiin heerkul jel oo kala duwan, taas oo ah sifooyinka kuleylka kuleylka ee HydroxyethylMethylCilose(HEMC). Solubility wuxuu la beddelaa viscosity. Maqnaanshaha hoose, waa ka sii weynaanta milanka. Tilmaamaha kala duwan ee HydroxyethylMethylCilose(HEMC)waxay leeyihiin kala duwanaansho gaar ah xagga waxqabadka.
Kala dirida HydroxyethylMethylCilose(HEMC)biyaha dhexdiisa ma saamayso pH. Saamaynta qiimaha HydroxyethylMethylCilose(HEMC)waa ku milma biyaha kulul, waana mid aan lagu milmi karin inta badan dareerayaasha organic. Hydroxyethyl oogada lagu daweeyayMethylCilose(HEMC)ku kala firdhiyo biyo qabow iyada oo aan la kicin oo si tartiib ah u milaan, laakiin si dhakhso ah ayaa loo milmi karaa iyada oo la hagaajinayo qiimaha pH ilaa 8 ~ 10. xasilloonida ph: isbeddelka viscosity-ku wuu yar yahay inta u dhaxaysa qiimaha ph laga bilaabo 2 ilaa 12, viscosity-kuna wuu yaraadaa wixii ka baxsan xadkan.

Habka kala dirida
Ku dar 1/3 cadadka biyaha nadiifka ah ee la cayimay weelka. Ku dar hydroxyethyl methyl cellulose (HEMC) hoos walaaqaya xawaare hooseeya, oo walaaq ilaa dhammaan agabku ay si buuxda u qoyan yihiin. Ku dar maaddooyinka kale ee caanaha oo si fiican isku walaaq. Ku dheji qadarka la cayimay ee biyaha qabow si aad u qaboojiso oo u milmaan.
Codsiyada:
1.Dry Hoobiye isku qasan
Haysashada sare ee biyaha waxay si buuxda u nuujin kartaa sibidhka, waxay si weyn u kordhin kartaa xoogga isku-xidhka, isla markaana waxay si habboon u kordhin kartaa xoogga jilicsanaanta iyo xoogga dhogorta, waxay si weyn u wanaajisaa saameynta dhismaha waxayna kordhisaa waxtarka shaqada.
2.Wall putty
Ether-ka cellulose ee ku jira budada putty waxa ay inta badan door ka ciyaartaa xajinta biyaha, isku xidhka iyo sifaynta, ka ilaalinta dildilaaca iyo fuuqbaxa ay keenaan luminta biyaha aad u degdega ah, isla markaana kor u qaadaysa ku dhegga dufanka, hoos u dhigida ifafaalaha hoos u dhaca inta lagu jiro dhismaha, iyo samaynta dhismaha si fudud.
- Gypsum Plaster
Alaabooyinka taxanaha gypsum-ka, eter-ka cellulose-ku wuxuu inta badan ka ciyaaraa doorka ilaalinta biyaha iyo kordhinta saliidda. Isla mar ahaantaana, waxay leedahay saameyn dib u dhac gaar ah. Waxay xallisaa dhibaatooyinka soo-baxa iyo xoogga bilowga ah oo aan ku filnayn inta lagu jiro habka dhismaha, waxayna kordhin kartaa wakhtiga shaqada.
4.Interface wakiilka
Inta badan loo isticmaalo dhumuc ahaan, waxay wanaajin kartaa xoogga xajinta iyo xoogga xiirta, hagaajinta dahaarka dusha sare, iyo kor u qaadida adhesion iyo xoojinta xoogga.
5.Hoobiye dahaarka kulaylka dibadda
Eter cellulose ee maaddadan ayaa inta badan ka ciyaara doorka isku-xidhka iyo kordhinta xoogga. Ciiddu way fududaan doontaa in la huwado, wanaajiso hufnaanta shaqada, iyo saamaynta ka-hortagga sagging. Waxqabadka sare ee haynta biyaha waxay kordhin kartaa wakhtiga shaqada ee hoobiye waxayna kordhin kartaa caabbinta. Iska caabinta dildilaaca iyo dildilaaca, wanaaji tayada dusha sare, oo kordhi xoogga isku xidhka.
6.Xabagta Dusha
Haysashada sare ee biyaha waxay meesha ka saartaa baahida horay loo qooyay ama qoyn lahaa tiirarka iyo saldhigyada, taasoo si weyn u wanaajisay xooggooda isku-xidhka. Qulqulka waxaa lagu dhisi karaa waqti dheer, ganaax, isku mid ah, dhismo ku habboon, iyo caabbinta wanaagsan ee qoynta iyo socdaalka.
- TileGout,wadajirbuuxin
Ku-darka ether-ka cellulose wuxuu ka dhigayaa inuu leeyahay adhesion cirifka wanaagsan, hoos u hooseeya iyo caabbinta sare ee caabbinta, waxay ka ilaalisaa walxaha asaasiga ah ee waxyeellada farsamada, waxayna ka fogaanaysaa saameynta dhexgalka dhismaha oo dhan.
8.Walax is-milliminta
Isku-duubnida xasilloon ee ether-ka cellulose waxay hubisaa dareeraha wanaagsan iyo kartida is-beddelka, waxayna xakameysaa heerka xajinta biyaha si ay u suurtageliso adkeyn degdeg ah oo ay yareyso dildilaaca iyo hoos u dhaca.
