I-cellulose ethers
I-cellulose ethers lusapho lweepolysaccharides ezithathwe kwi-cellulose, eyona polymer yendalo ininzi emhlabeni. Ziyakwazi ukunyibilika emanzini kwaye zinoluhlu olubanzi lwezicelo kumashishini ahlukeneyo, kubandakanya ukutya, amayeza, izinto zokuthambisa, kunye nokwakha. Kweli nqaku, siza kuxubusha iipropati, imveliso, kunye nokusetyenziswa kwe-cellulose ethers ngokweenkcukacha.
Iipropati zeCellulose Ethers
I-Cellulose ethers inendibaniselwano eyodwa yeepropathi ezenza zibe luncedo kakhulu kwizicelo ezahlukeneyo. Ezinye zeempawu eziphambili ze-cellulose ethers ziquka:
Ukunyibilika kwamanzi: I-ethers ye-cellulose i-soluble kakhulu emanzini, nto leyo eyenza kube lula ukuyisebenzisa kwiinkqubo ezinamanzi. Le propati ikwabenza ukuba babe zizityebi ezisebenzayo kunye nezinzisi ekutyeni nasekuxutyweni kwamayeza.
Iipropati Zokwenza Ifilimu: I-cellulose ethers inokwenza ifilimu ecacileyo, eguquguqukayo, kwaye eyomeleleyo xa inyibilikiswa emanzini. Le propati iluncedo kwimveliso yeengubo, i-adhesives, kunye neefilimu.
Ukuzinza kweMichiza: Ii-ether ze-cellulose zizinzile kwiikhemikhali kwaye zixhathisa ukuthotywa kwe-microbial, ezenza zilungele ukusetyenziswa kwizicelo ezahlukeneyo zoshishino.
I-Non-Toxicity: I-cellulose ethers ayinayo ityhefu kwaye ikhuselekile ukuba isetyenziswe ekutyeni, kumayeza, nakwiimveliso zokhathalelo lomntu.
Ukuveliswa kweCellulose Ethers
I-cellulose ethers iveliswa ngokuguqula i-cellulose ngokuphendula kweekhemikhali kunye namaqela ahlukeneyo asebenzayo. Iindidi eziqhelekileyo ze-cellulose ethers ziquka:
I-Methylcellulose (MC): I-Methylcellulose iveliswa ngokuphendula i-cellulose kunye ne-methyl chloride kunye ne-sodium hydroxide. Isetyenziswa ngokubanzi njenge-thickener kunye ne-stabilizer ekutyeni nasekuxubeni amayeza.
I-Hydroxypropyl Cellulose (HPC): I-cellulose ye-Hydroxypropyl iveliswa ngokuphendula i-cellulose kunye ne-propylene oxide kunye ne-hydrochloric acid. Isetyenziswa njenge-binder, emulsifier, kunye ne-thickener kukutya, amayeza, kunye neemveliso zokhathalelo lomntu.
I-Ethylcellulose (EC): I-Ethylcellulose iveliswa ngokuphendula i-cellulose kunye ne-ethyl chloride kunye ne-sodium hydroxide. Isetyenziswa njenge-binder, ifilimu-yangaphambili, kunye ne-ejenti yokugquma kumashishini amayeza kunye nokunyamekela komntu.
I-Carboxymethyl Cellulose (CMC): I-Carboxymethyl cellulose iveliswa ngokuphendula i-cellulose kunye ne-chloroacetic acid kunye ne-sodium hydroxide. Isetyenziswa njenge-thickener, stabilizer, kunye ne-emulsifier kumashishini okutya, amayeza, kunye nokhathalelo lomntu.
I-Hydroxyethyl Cellulose (HEC): I-cellulose ye-Hydroxyethyl iveliswa ngokuphendula i-cellulose kunye ne-ethylene oxide kunye ne-sodium hydroxide. Isetyenziswa njenge-thickener, stabilizer, kunye ne-emulsifier kumashishini okutya, amayeza, kunye nokhathalelo lomntu.
Ukusetyenziswa kweCellulose Ethers
I-cellulose ethers inoluhlu olubanzi lwezicelo kumashishini ahlukeneyo, kuquka:
Ishishini lokutya: I-cellulose ethers isetyenziswa ngokubanzi njengezinto ezityebisayo, izinzisi, kunye ne-emulsifiers ekuxutyweni kokutya. Zisetyenziswa kwiimveliso ezifana ne-ayisikrimu, iisosi, izinxibo kunye nezinto ezibhakiweyo.
Umzi-mveliso woShishino: Ii-ether ze-cellulose zisetyenziswa njengezibophelelo, ii-disintegrants, kunye ne-coatings ekuxutyweni kwamayeza. Zisetyenziswa kwiipilisi, iipilisi, kunye nezinye iifom zedosi eqinile.
Umzi-mveliso wokuKhathalela uBuqu: I-ethers zeCellulose zisetyenziswa njengezityebi, izizinzi, kunye nezithambiso kwiimveliso zokhathalelo lomntu ezifana neeshampu, izinto zokuthambisa, kunye neekhrimu.
Ishishini Lokwakha: Ii<em>cellulose ethers zisetyenziswa njengeejenti zokugcina amanzi, ii<em>thickeners, nezibophelelo kwizinto zokwakha ezifana nesamente, udaka.
