Udaka olomileyo sisixhobo sokwakha esinesanti, isamente kunye nezinye izongezo. Isetyenziselwa ukudibanisa izitena, iibhloko kunye nezinye izinto zokwakha ukudala izakhiwo. Nangona kunjalo, udaka olomileyo akusoloko kulula ukusebenza ngalo njengoko luthanda ukuphulukana namanzi kwaye lube nzima kakhulu ngokukhawuleza. I-cellulose ethers, ngakumbi i-hydroxypropylmethylcellulose (HPMC) kunye ne-methylhydroxyethylcellulose (MHEC), ngamanye amaxesha yongezwa kumdaka owomileyo ukuze kuphuculwe iipropati zokugcina amanzi. Injongo yale nqaku kukuhlola izibonelelo zokusebenzisa i-cellulose ether kwidaka elomileyo kunye nendlela enokuphucula ngayo umgangatho wokwakha.
Ugcino lwamanzi:
Ukugcinwa kwamanzi kudlala indima ebalulekileyo kumgangatho wodaka olomileyo. Ukugcina ubumanzi obuchanekileyo buyimfuneko ukuze kuqinisekiswe ukuba udaka lubeka ngokufanelekileyo kwaye lwenza ibhondi eyomeleleyo phakathi kwezinto zokwakha. Nangona kunjalo, udaka olomileyo luphulukana nokufuma ngokukhawuleza, ngakumbi kwiimeko ezishushu nezomileyo, nto leyo ekhokelela kudaka olukumgangatho ophantsi. Ukusombulula le ngxaki, i-cellulose ethers ngamanye amaxesha yongezwa kwidaka elomileyo ukuze kuphuculwe iimpawu zokugcinwa kwamanzi.
I-cellulose ethers zi-polymers ezivela kwi-cellulose, i-fiber yendalo efumaneka kwizityalo. I-HPMC kunye ne-MHEC zimbini iintlobo ze-cellulose ethers eziqhelekileyo zongezwa kumdaka owomileyo ukuphucula ukugcinwa kwamanzi. Basebenza ngokwenza into efana nejeli xa ixutywe namanzi, nto leyo enceda ukuthothisa inkqubo yokomisa kodaka.
Iingenelo zokusebenzisa i-cellulose ether kudaka olomileyo:
Kukho iingenelo ezininzi zokusebenzisa i-cellulose ethers kudaka olomileyo, kubandakanya:
1. Ukuphucula ukusebenza: I-ether ye-cellulose inokuphucula ukusebenza kodaka olomileyo ngokunciphisa ukuqina kwayo kunye nokwandisa iplastiki yayo. Oku kwenza kube lula ukufaka udaka kwizinto zokwakha ukuze kugqitywe ngobuhle.
2. Ukuncipha kokuqhekeka: Udaka olomileyo lunokuqhekeka xa loma ngokukhawuleza, lubeka esichengeni amandla alo. Ngokudibanisa i-cellulose ether kumxube, udaka loma kancinci kancinci, lunciphisa umngcipheko wokuqhekeka kunye nokwandisa amandla awo.
3. Ukonyuka kwamandla ebhondi: Ukubophelela kodaka olomileyo kwizinto zokwakha kubalulekile ekusebenzeni kwayo. I-Cellulose ethers yandisa ukugcinwa kwamanzi kwi-mortar, eyandisa amandla ayo ebhondi, okukhokelela ekubeni ibhondi eyomeleleyo, ehlala ixesha elide.
4. Ukuphucula ukuqina: I-ether ye-cellulose inokuphucula ukuqina kodaka olomileyo ngokunciphisa inani lamanzi alahlekileyo ngexesha lokumisa. Ngokugcina amanzi amaninzi, udaka alunakwenzeka ukuba luqhekeke okanye luqhekeke, nto leyo eyenza ukuba isakhiwo sihlale ixesha elide.
Udaka olomileyo luyinto ebalulekileyo ekwakheni. Nangona kunjalo, iimpawu zayo zokugcina amanzi kunokuba nzima ukulawula, okukhokelela kudaka olukumgangatho ophantsi. Ukongeza i-cellulose ethers, ngakumbi i-HPMC kunye ne-MHEC, ukomisa udaka kunokuphucula kakhulu ukusebenza kwayo kokugcinwa kwamanzi, okukhokelela kwimveliso ephezulu. Izibonelelo zokusebenzisa i-cellulose ethers kwi-mortars eyomileyo ibandakanya ukuphuculwa kokusebenza, ukunciphisa ukuqhekeka, ukuphuculwa kwamandla ebhondi kunye nokwanda kokuqina. Ngokusebenzisa i-cellulose ethers kwidaka elomileyo, abakhi banokuqinisekisa ukuba izakhiwo zabo zomelele, zihlala zihlala kwaye zibukeka kakuhle.
