Hydroxypropylykyl methyrellose ether (HPMC) waxay leedahay haynta biyaha iyo saamaynta qarosiinta hoolka iyo hoobiyeynta ku saleysan, waxayna si macquul ah u horumarin karaan adhesion iyo iska caabbinta tooska ah ee hoobinada.
Waxyaabaha ay ka mid yihiin heerkulka gaaska, heerkulka, iyo heerka cadaadiska gaaska ayaa waxyeello u leh heerka uumiga uumiga ee biyaha ee hoolka ee hoolka iyo alaabada ku saleysan gypsum. Sidaa darteed, isla tirada guud ee ganacsiga ganacsiga hydroxypropyl methylulolose ether (HPMC) ayaa lagu daray in la ilaaliyo helitaanka biyuhu way kala duwan yihiin xilli xilli ilaa xilli ilaa xilli.
Markaad shubinayso wax la taaban karo, saamaynta qufulka biyaha ayaa lagu hagaajin karaa iyadoo loo eegayo kororka ama yareynta heerka socodka sare. Heerka qufulka biyaha ee hydroxypropyl playlrellalose ether heerkulka sare waa qiimaha ugu weyn ee tilmaame si loo kala sooco tayada hydroxypropyl chether.
Qalabka tayada sare leh ee tayada sare ee hydroxypropyl methylrcelrelose ether (HPMC) ayaa si macquul ah u baabi'in kara dhibaatada qufulka biyaha heerkulka. Xilliyada heerkulka sare, gaar ahaan meelaha kulul iyo qoyaanka iyo dhismayaasha injineerinta ee korontada, waxaa lagama maarmaan ah in la isticmaalo tayada tayo sare leh ee hydroxypropyl choth methylulose ether (HPMC) si loo wanaajiyo jilitaanka biyaha ee slurry.
Saamiga tayada tayo sare leh ee hydroxypropyl chothertellerose ether (HPMC) waa labis aad u lebbiska ah, oo loo yaqaan 'chomroxypropyl'. Awoodda dammaanad-gal-siinta si loo shaqeeyo.
Waxay si macquul ah u xakameyn kartaa uumi-baxa biyaha ay keento cimilada kulul oo ay ku guuleystaan saameynta dhabta ah ee qufulka biyaha sare. Qalabka tayada sare leh ee tayada sare-sare
Dhamaan walxaha adag ayaa loo diidayaa inay sameeyaan filim qoyan. Biyaha caadiga ah si tartiib tartiib ah ayaa loo sii daayaa muddo dheer oo waxaa lagu sameeyaa falcelin isku-dhafan oo ku saabsan agabyada inorganic iyo agab wadajirka ah si loo hubiyo isku xirka xoogga isku-darka ah iyo xoogga khafiifka ah.
Sidaa darteed, goobaha dhismaha heerkulka ee heerkulka xagaaga, si loo gaaro saameynta dhabta ah ee keydinta biyaha, dadku waa inay ku daraan biyo-ku-takoorka tayada leh (HPMC) iyadoo loo eegayo biyaha qarsoodiga ah, haddii ay biyuhu ka gaabiyaan biyo yaraanta. Arimaha tayada wax soo saarka sida xoojinta, yareynta xoogga isku-dhafka ah, dildilaaca, dillaacyada hawada, iwm.
Tani waxay sidoo kale kordhineysaa dhibaatada dhibaatada ee shaqaalaha. Maaddaama heerkulku yaraado, qaddarka lagu daray ee hydroxypropyl methylrellalose ether (HPMC) si tartiib tartiib ah ayuu u yaraanayaa si loo gaaro isla qoyaan isku mid ah.
