Muujinta saamaynta haynta biyaha ether cellulose

Eter-ka Cellulose wuxuu leeyahay saameyn wanaagsan oo haynta biyaha.

Eter cellulose waa wax lagu daro caan ah oo ku jira hoobiye qalalan, kaas oo ka ciyaara door aad u muhiim ah.

Hoobiye in ether cellulose kala diri biyaha, sababtoo ah dusha doorka firfircoon si loo hubiyo in wax ku ool ah gelled qaybinta lebis ee nidaamka, iyo ether ether cellulose sida nooc ka mid ah kolloid ilaalinta, "xirmo" Qurub adag, iyo dusha dibadda si ay u sameeyaan lakabka ah. filimka sifaynta, nidaamka slurry aad u xasiloon, iyo sidoo kale hagaajinaysaa slurry ee habka isku dhafka ah ee dareeraha iyo dhismaha silballada laga yaabaa in sidoo kale.

Xalka ether Cellulose ay sabab u tahay sifooyinka qaab-dhismeedka kelli u gaar ah, si biyaha hoobiye ma fududa in ay lumin, iyo in muddo xoog leh si tartiib tartiib ah sii daayay, siinta hoobiye haynta wanaagsan iyo workability.

Haysashada biyaha ee ether-ka cellulose waa tusaha xogta muhiimka ah iyo aasaasiga ah, haynta biyaha waxaa loola jeedaa haynta biyaha ee hoobiye cusub oo isku dhafan oo ku yaal substrate hydrophobic ka dib ficilka xididka.

Halkan oo leh hab tijaabo ah oo fudud, si fudud u tus qaybta I cellulose ether saamaynta haynta biyaha, kaliya ee daawashada oh!

Eter cellulose

Sababtoo ah ma jiro hab tijaabo ah oo midaysan oo loogu talagalay haynta biyaha ee ether-ka cellulose ee dalka, ganacsiga wax-soo-saarka inta badan ma bixiyo xuduudaha farsamada.

Laakiin si loo helo ku habboonaanta isticmaalka iyo qiimaynta macaamiisha, laba hab oo xirfadleyaal ah oo lagu tijaabiyo haynta biyaha cellulose ether ayaa inta badan lagu isticmaalaa warshadaha: Habka vacuum iyo habka waraaqaha filter.

Haddii aad u baahan tahay xogtan tixraac ahaan, fadlan nala soo xiriir xiriir faahfaahsan.

Shirkaddayada istaarijka gudaha ether, waa hydroxypropyl istaarijka ether (HPS), nooc ka mid ah dhirta dabiiciga ah sida alaabta ceeriin, ka dib markii wax laga beddelo, falcelin heer sare ah etherified, ka dibna ku buufiyo qalajinta iyo budo cad cad, oo aan caag.

Qalabka jirka: budada cad, dareeraha wanaagsan, milanka biyaha wanaagsan, xalkeeda aqueous aan midab lahayn, xasilooni dhalaalaysa baraf wanaagsan.

Tilmaamaha codsiga:

1. Hoobiyaha si degdeg ah ayaa loo dhumucdi karaa;

2. Viscosity dhexdhexaad ah, oo leh biyo-hayn gaar ah;

3. Qiyaas yar, qiyaasta aadka u hooseeya waxay gaari kartaa saameyn wanaagsan;

4. Hagaajinta awoodda ka-hortagga-laad-qaadka agabka;

5. Hagaajinta shaqada hoobiye, si dhismuhu u noqdo mid siman;

6. Kordhi wakhtiga furitaanka hoobiye.

Codsiga Alaabta:

Madaafiicda sibidhka ku salaysan: Biyo adkaysi u leh gidaarada gudaha iyo dibaddaba, dhoobada dhoobada ah ee xabagta, xabagta dhoobada dhoobada ah, wakiilka isku xidhka, hoobiye dahaarka inorganic;

Hoobiyaha saldhigga ah ee gypsum: gypsum putty, gypsum bonding hoobiye, gypsum malaasta hoobiye, hoobiye caulking gypsum, hoobiye gypsum dab, hoobiye gypsum insulation;

Dheecaan dhexdhexaad ah.
