Magaca kiimikada, hydroxypropyl bylulose (HPMC), hydroxyetyl bylulose (HMC), hydroxymetyl cellulose (MCC), methyl hydroxytyl (MHC), MHCOXYESNLEYS (MEC), MHCYL HYDroxyl (MHC), Etyl Kariimka hydroxyetyl (eHEC), eHC), ee kumbuyuutarrada ka buufiyey ee wax laga beddelay (EHEC, HM-EHEC).
Ethers antches-ka waxaa loogu talagalay isbedelada kiimikada ee cellulose oo leh qaar kale oo kiimiko ah. In ka badan 70 sano, alaabooyinkani waxay door muhiim ah ka ciyaareen codsiyadan, laga soo bilaabo badeecada naqshadeynta, dhoobada iyo rinjiyeynta cuntada, waxyaabaha la isku qurxiyo iyo dawooyinka. Qiyaasta unugyada ayaa loo shaqeeyaa sidii kiimikooyin shaqeynaya iyo midho leh iyo wax qabad sida wakaaladaha qarogashada, emififiers, difaacayaasha, xasilinta iyo sidoo kale haynta biyaha.
Dhismaha, kaynta qalliinka waxay u adeegaan sidii dhumucyo, kuwa wax lagu miiraayo, qaab dhismeedka sawirka iyo biyo-la'aanta, ganaaxyada, saliidaha, saliidaha, saliidaha is-difaaca iyo emulsifiers. Intaa waxaa sii dheer, dawooyinka aqueous ee qalliin gaar ah oo ka shaqeeya gel silmad, oo ah guri gaar ah oo qaadaya mowqif muhiim ah barnaamijyo kala duwan. Isku-darkan qiimaha leh ee sifooyinka runtii kuma eka inta badan oo kale oo isdaba joog ah H2O-soluble polymer.
Runta ah in guryaha la tirin karo ee la tiriyo ay jiraan isku mar oo ay badanaa ka jawaabaan isku dhafka waxay noqon kartaa faa iido lacageed oo muhiim ah. Dhowr barnaamij, in badan oo ka kooban maaddooyin ayaa loo baahan doonaa in lagu sameeyo shaqada isku midka ah ee ay sameeyeen ganacsade Chul Chert oo shaqsi ah. Intaas waxaa sii dheer, anshaxa unugyada unugyada si aad ah ayey ugu guuleysteen, inta badan waxay dhalinayaan wax ku oolnimada ugu wanaagsan ee diiradda la dhimayso diiradda biyuhu ee biyaha ee la cabi karo ..

Cilmisaadka walaaca waxay ku adkeystaan aragtida horumarka 'heer sare, qaab-dhismeed sare, qaab shaqo oo ku-tiirsanaanta ah, oo tayo sare leh, oo tayo sare leh, si aad u ogaato shuruudaada cabir kasta si aan si fudud kuugu wargalin karno si fudud.
Iibinta kulul ee Shiinaha ee Qiyaasta China Ethers, si ay u ilaaliso jagada hogaaminta warshadeena, waligeen ma joojineynaa xadadka xadka dhammaan dhinacyada si aan u abuuro xalka ugu habboon. Jidkiisa, waxaan kobcin karnaa qaabka nolosheena oo aan horumarin karno jawi wanaagsan oo ku habboon bulshada adduunka.
