Ulwakhiwo lweMichiza kunye noMvelisi we-Cellulose Ether
I-cellulose ethersyintsapho yeepolymers ezinyibilikayo zamanzi ezivela kwi-cellulose, i-polymer yendalo efumaneka kwiindonga zeseli zezityalo. Ukwakhiwa kweekhemikhali ze-cellulose ethers kufezekiswa ngokuguqulwa kweekhemikhali zeselulosi ngokuzisa amaqela ahlukeneyo e-ether. I-cellulose ethers eziqhelekileyo ziquka i-Hydroxyethyl Cellulose (HEC), i-Hydroxypropyl Methylcellulose (HPMC), i-Methyl Cellulose (MC), i-Carboxymethyl Cellulose (CMC), kunye nabanye. Ulwakhiwo lweekhemikhali zezi ether zeselulosi zezi zilandelayo:
- I-Hydroxyethyl Cellulose (HEC):
- Amaqela e-Hydroxyethyl angeniswa kwisakhiwo se-cellulose.
- Ulwakhiwo lweMichiza: [Iselulosi] – [O-CH2-CH2-OH]
- IHydroxypropyl Methylcellulose (HPMC):
- I-Hydroxypropyl kunye namaqela e-methyl angeniswa kwisakhiwo se-cellulose.
- Ulwakhiwo lweMichiza: [Iselulosi] – [O-CH2-CHOH-CH3] kunye [O-CH3]
- I-Methyl Cellulose (MC):
- Amaqela e-Methyl angeniswa kwisakhiwo se-cellulose.
- Ulwakhiwo lweMichiza: [Iselulosi] – [O-CH3]
- I-Carboxymethyl Cellulose (CMC):
- Amaqela eCarboxymethyl angeniswa kwisakhiwo se-cellulose.
- Ulwakhiwo lweMichiza: [Iselulosi] – [O-CH2-COOH]
Ubume bekhemikhali obuchanekileyo bunokwahluka ngokusekelwe kwiqondo lokutshintshwa (DS) kunye nezinye izinto ezinxulumene nenkqubo yokuvelisa. Ukuqaliswa kwala maqela e-ether kunika iimpawu ezithile kwi-ether ye-cellulose nganye, njengokunyibilika kwamanzi, amandla okuqina, amandla okwenza ifilimu, kunye nokunye.
Abavelisi be-cellulose ethers baquka zombini iinkampani zehlabathi nezengingqi. Abanye abavelisi ababalaseleyo kwishishini le-cellulose ethers babandakanya:
- Kima Chemical:
- I-Kima Chemical yinkampani yeekhemikhali ze-cellulose ether zezizwe ngezizwe ezivelisa iindidi zeekhemikhali zeemveliso, kuquka i-cellulose ethers.
- Shin-Etsu:
- IShin-Etsu, eseJapan, yaziwa ngokwenza iimveliso ezahlukeneyo zemichiza, kubandakanya nezinto eziphuma kwiselulosi.
- I-Ashland Inc.:
- I-Ashland yinkampani yehlabathi yeekhemikhali ezikhethekileyo evelisa i-cellulose ethers phakathi kwezinye iimveliso.
- CP Kelco:
- I-CP Kelco ngumvelisi ohamba phambili wehlabathi jikelele wee-hydrocolloids ezikhethekileyo, kuquka i-cellulose ethers.
- AkzoNobel:
- I-AkzoNobel yinkampani yamazwe ngamazwe eyenza uluhlu lweekhemikhali ezikhethekileyo, kuquka i-cellulose ethers.
- I-Nouryon (eyayisakuba yi-AkzoNobel Specialty Chemicals):
- I-Nouryon ngumvelisi omkhulu weekhemikhali ezikhethekileyo, kwaye iqhubeka nelifa le-AkzoNobel Specialty Chemicals.
Ezi nkampani zinobukho obubonakalayo kwimarike ye-cellulose ethers kwaye zibonelela ngoluhlu lwamabakala kunye nokwahluka ukuhlangabezana neemfuno ezahlukeneyo zoshishino kunye nezorhwebo. Xa usebenzisa i-cellulose ethers, kubalulekile ukubhekisa kumaxwebhu athile emveliso anikezelwe ngumenzi ngolwazi oluthe kratya malunga nezakhiwo, amanqanaba okusetyenziswa acetyiswayo, kunye nezinye iinkcukacha zobugcisa.
