Umkhiqizi we-Hydroxyethyl cellulose

IHydroxyethyl cellulose (HEC) iyi-polymer encibilika emanzini engeyona i-ionic esetshenziswa kabanzi ezimbonini ezahlukahlukene ezifana nezamakhemisi, izimonyo, ezokwakha, nezindwangu. Njengengxenye eyinhloko ezinhlelweni eziningi zokusebenza, abakhiqizi be-HEC badlala indima ebalulekile ekukhiqizeni nasekusabalaliseni lo mkhiqizo onemisebenzi eminingi.

I-HEC iwukuphuma kwe-cellulose ether ekhiqizwa ngokushintsha amakhemikhali i-cellulose yemvelo. Inqubo yokukhiqiza iqala ngokuhlanzwa kwemicu ye-cellulose, kulandelwa i-etherification nge-ethylene oxide ne-mono-chloroacetic acid ukukhiqiza umkhiqizo wokugcina we-HEC. Izinga le-HEC lincike ekuhlanzekeni kweselulosi kanye nezinga lokushintsha (DS) lamaqembu e-ether kumgogodla we-cellulose.

Njengomkhiqizi ohamba phambili we-HEC, inkampani kufanele ibe nezinsiza zesimanje kanye nemishini yokuqinisekisa umkhiqizo wekhwalithi ephezulu kakhulu. Inqubo yokukhiqiza ye-HEC ibhalansi ethambile phakathi kwamakhemikhali nobunjiniyela, edinga ukulawulwa okunembile kwezimo zokusabela ezifana nezinga lokushisa, ingcindezi, nesikhathi sokusabela. Umkhiqizi we-HEC kufanele abe nobuchwepheshe bobuchwepheshe bokwandisa izimo zokusabela ukuze akhiqize i-HEC ngezakhiwo ezidingekayo nokusebenza.

Izakhiwo ze-HEC zingenziwa ngokwezifiso ngokushintsha i-DS yamaqembu e-ether kumgogodla we-cellulose. I-DS ephakeme iphumela ku-HEC ene-hydrophilic eyengeziwe enezakhiwo ezingcono zokugcina amanzi, kuyilapho i-DS ephansi ikhiqiza i-HEC ene-hydrophobic eyengeziwe enezici ezingcono zokujiya. Umkhiqizi we-HEC kufanele abe nekhono lokukhiqiza i-HEC enamanani ahlukene e-DS ukuze ahlangabezane nezidingo ezihlukahlukene zezinhlelo zokusebenza ezihlukahlukene.

Ngaphezu kokukhiqiza i-HEC ngezinto ezidingekayo, umenzi kufanele futhi aqinisekise ukuthi umkhiqizo uhlangabezana nezindinganiso zekhwalithi ezidingekayo. Ukuhlanzeka nokungaguquguquki kwe-HEC kubalulekile ekusebenzeni kwayo ezinhlelweni ezahlukahlukene. Umkhiqizi kufanele abe nesistimu yokulawula ikhwalithi eqinile ukuze aqaphe ikhwalithi yomkhiqizo kuzo zonke izigaba zenqubo yokukhiqiza. Umkhiqizi kufanele futhi enze ukuhlola okubanzi ukuze aqinisekise ukuthi umkhiqizo uhlangabezana nezimfuneko ezidingekayo zohlelo ngalunye.

Abakhiqizi be-HEC kufanele futhi bazinikele ekusimameni nasekubophezeleni kwemvelo. Ukukhiqizwa kwe-HEC kubandakanya ukusetshenziswa kwamakhemikhali namandla, futhi umenzi kufanele abe nezinyathelo ezikhona zokunciphisa umthelela emvelweni. Lokhu kubandakanya ukunciphisa udoti, izinto zokugaya kabusha, nokuthuthukisa ukusetshenziswa kwamandla.

Okokugcina, umenzi omuhle we-HEC kufanele anikeze isevisi yamakhasimende enhle kakhulu. Kufanele babe nethimba lesevisi yamakhasimende eliphendulayo nelinolwazi elingaphendula noma yimiphi imibuzo noma okubakhathazayo ngokushesha. Kufanele futhi banikeze ukwesekwa kobuchwepheshe kumakhasimende abo ukuze baqinisekise ukuthi umkhiqizo usetshenziswa ngendlela efanele nangempumelelo.

Sengiphetha, i-HEC iyingxenye ebalulekile ezimbonini eziningi, futhi umkhiqizi omuhle kakhulu we-HEC udlala indima ebalulekile ekukhiqizeni nasekusabalaliseni lo mkhiqizo. Kumele babe nezinsiza kanye nemishini yesimanjemanje, uchwepheshe bezobuchwepheshe, nokuzibophezela kwikhwalithi nokusimama. Ngokuhlinzeka ngomkhiqizo wekhwalithi ephezulu kanye nenkonzo yamakhasimende enhle kakhulu, abakhiqizi be-HEC bangasiza amakhasimende abo ukuba afinyelele impumelelo ezinhlelweni zabo zokusebenza.
