Is barbar dhig HEC vs HEMC ee bacriminta dareeraha ah oo baro sida ether kasta oo cellulose ah u saameeyo waafaqidnaanta nafaqeeyayaalka yar yar, viscosity, xasiloonida hakinta, kontoroolka pH, walxaha raadraaca ee la jeexjeexay, iyo waxqabadka bacriminta. Soo hel tillaabooyinka tijaabada ah ee qaabaynta bacriminta deggan.
Maqaalkani wuxuu isbarbar dhigayaa HPMC iyo HEMC dhimista xiisadda dusha sare iyo waxqabadka qoynta ee dhismaha iyo codsiyada kiimikada maalinlaha ah. Waxay sharraxaysaa kala duwanaanshaha kiimikaad ee u dhexeeya Hydroxypropyl Methyl Cellulose iyo Hydroxyethyl Methyl Cellulose, waxay qiimeysaa saamaynta ay ku leeyihiin faafitaanka, viscosity, haynta biyaha, shaqaynta, iyo adhesion, waxayna bixisaa hagitaan wax ku ool ah oo loogu talagalay xulashada darajada etherka cellulose ee saxda ah ee koolada tile, dhejinta gidaarka, bixinta sibidhka, jaakad skim ah, balaastarka gypss-ka.
Soo ogow sida heerka-dhismaha ee HPMC ay u wanaajiso xabagta tile-ka, hoobiye sibidhka, galka gidaarka, malaasta gypsum-ka, EIFS, iyo iskudhisyada is-mijaarka. Baro hababka haynta biyaha ee HPMC, qodobbada xulashada, hababka tijaabinta, iyo fikradaha samaynta ee soo saaraha ether-ka cellulose ee xirfada leh.
Hydroxypropyl Methylcellulose (HPMC) waxaa si weyn loogu isticmaalaa xabagta tile, hoobiyeyaasha qallalan ee qallalan, suufka gidaarka, malaasta gypsum, shaambo, dhaqidda jirka, kiriimyada, jelka, cuntada, dawooyinka, ceramics, dahaarka, iyo xabagta. Baro sida HPMC u wanaajiso viscosity, haynta biyaha, xasiloonida, shaqaynta, iyo waxqabadka alaabta.
Soo ogow faa'iidooyinka cellulose HPMC ee ku jira xabagta tile, hoobiye-qalalan-qallalan, darbiga suufka, alaabta gypsum, iyo qaababka daryeelka shakhsi ahaaneed. Baro sida HPMC u wanaajiso haynta biyaha, shaqaynta, viscosity, wakhtiga furan, xasiloonida, iyo joogteynta alaabta, oo ay la socoto hagida khabiirka doorashada darajada saxda ah.
Hypromellose, oo sidoo kale loo yaqaan hydroxypropyl methylcellulose ama HPMC, ayaa si weyn loogu isticmaalaa daawooyinka afka, dhibcaha indhaha, cuntada, kaabayaasha, qurxinta, iyo alaabta warshadaha. Maqaalkani waxa uu sharxayaa waxyeelooyinka suurtagalka ah ee hypromellose, oo ay ku jiraan raaxo-daro dheef-shiid kiimikaad oo ku meel gaar ah, xanaaqa isha ku-meel-gaadhka ah, dareen-celinta xasaasiyadeed ee naadir ah, hagida isticmaalka badbaadada ah, kala duwanaanshaha darajada HPMC, iyo tixgelinta tayada ee soosaarayaasha.
