I-ether ye-cellulose kwikhonkrithi

I-ether ye-cellulose luhlobo lwepolymer e-soluble yamanzi esetyenziswa kwiinkqubo ezahlukeneyo, kuquka ikhonkrithi. Eli phepha liphonononga ukusetyenziswa kwe-cellulose ether kwikhonkrithi kunye nemiphumo yayo kwiipropati zekhonkrithi. Iphepha lixoxa ngeentlobo ze-cellulose ethers ezisetyenziswe kwikhonkrithi, iimpembelelo zabo kwiimpawu zekhonkrithi, kunye neenzuzo kunye nokungahambi kakuhle kokusebenzisa i-cellulose ethers kwikhonkrithi. Iphepha liphinda liphonononge uphando lwangoku malunga nokusetyenziswa kwe-cellulose ethers kwikhonkrithi kwaye inika iingcebiso zophando lwexesha elizayo.

Intshayelelo

I-cellulose ethers luhlobo lwepolymer e-soluble yamanzi esetyenzisiweyo kwiinkqubo ezahlukeneyo, kuquka ikhonkrithi. I-cellulose ethers isetyenziselwa ukuphucula ukusebenza, amandla, kunye nokuqina kwekhonkrithi. Zikwasetyenziselwa ukunciphisa ukungena kwamanzi, ukuphucula ukunamathela, kunye nokunciphisa ukucutheka. I-cellulose ethers yongezwa kwikhonkrithi ngohlobo lomxube wolwelo okanye umgubo. Eli phepha liphonononga ukusetyenziswa kwe-cellulose ethers kwikhonkrithi kunye nemiphumo yayo kwiipropati zekhonkrithi.

Iindidi zeCellulose Ethers

I-cellulose ethers ihlukaniswe ngamacandelo amabini amakhulu: i-hydroxyethylcellulose (HEC) kunye ne-hydroxypropylcellulose (HPC). I-HEC i-ether ye-cellulose engeyiyo i-ionic esetyenziswa kwikhonkrithi ukuphucula ukusebenza, ukunciphisa ukunyanzeliswa kwamanzi, kunye nokunciphisa ukuncipha. I-HPC yi-anionic cellulose ether esetyenziselwa ukuphucula ukunamathela kunye nokunciphisa ukunyanzeliswa kwamanzi.

Iziphumo kwiiPropati zeConcrete

Ukusetyenziswa kwe-cellulose ethers kwikhonkrithi kunokuba nempembelelo ebalulekileyo kwiipropati zekhonkrithi. I-cellulose ethers inokuphucula ukusebenza kwekhonkrithi ngokunyusa ukuhamba komxube wekhonkrithi. Oku kunokunciphisa ubungakanani bamanzi afunekayo ukufezekisa ukusebenza okunqwenelekayo. I-cellulose ethers inokunciphisa ukunyanzeliswa kwamanzi kunye nokunciphisa, okunokuphucula ukuqina kwekhonkrithi. Ukongezelela, i-cellulose ethers inokuphucula ukubambelela phakathi kwekhonkrithi kunye nezinye izinto, ezifana nentsimbi okanye umthi.

Izinto eziluncedo nezingeloncedo

Ukusetyenziswa kwe-cellulose ethers kwikhonkrithi kuneenzuzo ezininzi. I-cellulose ethers inokuphucula ukusebenza kwekhonkrithi, ukunciphisa ukunyanzeliswa kwamanzi kunye nokunciphisa, kunye nokuphucula ukubambelela. Ukongeza, ii-cellulose ethers azibizi kakhulu kwaye kulula ukuzisebenzisa. Nangona kunjalo, kukho izinto ezingalunganga zokusebenzisa i-cellulose ethers kwikhonkrithi. I-cellulose ethers inokunciphisa amandla ekhonkrithi, kwaye inokunciphisa umthamo womoya wekhonkrithi, enokunciphisa ukuqina kwekhonkrithi.

Uphando lwangoku

Kukho inani elibalulekileyo lophando olwenziwe malunga nokusetyenziswa kwe-cellulose ethers kwikhonkrithi. Uphononongo lubonise ukuba i-cellulose ethers inokuphucula ukusebenza kunye nokunciphisa ukunyanzeliswa kwamanzi kunye nokunciphisa ikhonkrithi. Ukongezelela, uphando lubonise ukuba i-cellulose ethers inokuphucula ukunamathela kwekhonkrithi kwezinye izinto. Nangona kunjalo, kusekho imfuneko yophando olongezelelweyo ukuqonda ngcono iimpembelelo ze-cellulose ethers kwiipropati zekhonkrithi.

Ukuqukumbela

I-cellulose ethers luhlobo lwepolymer e-soluble yamanzi esetyenziswa kwiinkqubo ezahlukeneyo, kuquka ikhonkrithi. I-cellulose ethers inokuphucula ukusebenza, amandla, kunye nokuqina kwekhonkrithi. Banokunciphisa ukunyanzeliswa kwamanzi kunye nokunciphisa, kunye nokuphucula ukunamathela. Kukho inani elibalulekileyo lophando olwenziwe malunga nokusetyenziswa kwe-cellulose ethers kwikhonkrithi, kodwa kusekho imfuneko yophando olongezelelweyo ukuqonda ngcono imiphumo ye-cellulose ethers kwiipropati zekhonkrithi.
