Kala soocidda chether chett
Cilmiga Chether Ether waa eray guud oo ah badeecooyin taxane ah oo ay soo saartay falcelinta unugyada alkali iyo wakiilka ehelka ah ee xaaladaha qaarkood. Markii Alkalilulose loo beddelo wakiilo kaladuwan oo kaladuwan, anshax ka kooban unugyo kala duwan ayaa la heli doonaa.
Sida ku xusan dhismayaasha ionization ee wax lagu beddelo, anshaxa unugyada unugyada ayaa loo qaybin karaa laba qaybood: ionic (sida carborbytytyl cellulose) iyo nonionalc (sida menulyl by metlulose).
Marka loo eego nooca beddelka ah, chether chether ayaa loo qaybin karaa go'doomin (sida methyl bluetyl) iyo ether isku dhafan (sida itdroxypropyl bylulose).
Marka loo eego jilicsanaanta kaladuwan, waxaa loo qaybin karaa silsilado biyo ah (sida hyroxyetyl cellulose) iyo miraha soltval-ka ee dabiiciga ah (sida unugyada chetyl cellulose).
Qormada unugyada biyaha-ku-milma ee loo adeegsado madaafiicda isku dhafka ah ayaa loo qaybiyaa meel deg deg ah iyo dib-u-dhac ku dhaca-dib-u-dhacaya
Aaway khilaafaadkooda? Iyo sida si habsami leh loogu habeeyo 2% xalka aqueous ee tijaabada viscosity?
Waa maxay daaweynta dusha sare?
Saamaynta cherther chether ether?
kowaad
Daweynta dusha sare waa hab si dabiici ah u sameynta lakabka dusha sare ee dusha sare ee sheyga saldhiga leh, jireed iyo kiimiko iyo kiimiko ah oo ka duwan kan salka.
Ujeedada lagu daweyn karo dusha sare ee cely cetherku waa inuu daahiyo waqtiga cylring ether oo biyo ah si uu u buuxiyo shuruudaha dhirta ee yar yar ee madaafiicda, iyo in la kordhiyo iska caabbinta dhiigga ee celle-ka iyo hagaajinta xasilloonida.
Farqiga markii biyaha qabow lagu habeeyo 2% xalka aqueous:
Cell-ka-gacanta ee dusha lagu daweeyey ayaa si dhakhso leh u kala firdhisan kara biyaha qabow mana sahlana in ammagmomenatic sababo la xiriira muuqaalka gaabis ah;
Cill ether oo aan lahayn daweyn dusha sare, oo ay sabab u tahay viscocom-ka soonka soo noqda, ayaa viscous ka hor intaanay gebi ahaanba lagu kala firdhin biyo qabow, oo uu u nugul yahay ammaanta.
Sidee loo habeeyaa unugyada unugyada-dusha sare ee aan lagu daaweyn karin ether?
1. Marka hore geli xaddi cayiman oo unug-dusha sare-dusha sare ah.
2. Ka dib ku dar biyo kulul ilaa 80 digrii Celsius, culaysku waa saddex-meelood meel tirada mugga biyaha ee loo baahan yahay, si ay si buuxda u bararto oo kala firidhnaado;
3. Marka xigta, si tartiib ah ugu shub biyo qabow, culeysku waa saddex-meelood laba meelood oo biyaha haray, oo kareyso inuu si tartiib ah u dhejiyo, oo ma jiri doono dad-isgglmation;
4. Ugu dambeyntiina, hoostiisa xaaladda miisaanka isku mid ah, ku rid qubeyska biyaha joogtada ah ilaa heerkulka uu hoos u dhaco 20 digrii Celsius, ka dibna baaritaanka viscous-ka ayaa la fulin karaa!
