Iimveliso zodaka zomxube owomileyo kushishino lokwakha ziye zahambela phambili kakhulu kule minyaka idlulileyo.Ezi mveliso ziye zaduma ngenxa yokusebenziseka kwazo, ukuguquguquka, kunye nokulula ukusetyenziswa.Inkqubela phambili ephambili kwiimveliso zodaka ezomileyo kukusetyenziswa kwe-hydroxypropylmethylcellulose (HPMC) kunye ne-methylhydroxyethylcellulose (MHEC).Ezi cellulose ethers zisetyenziswa ngokubanzi kwimveliso yodaka oluxubeneyo elomileyo kwaye zibonelela abasebenzisi ngeenzuzo ezininzi.Kweli nqaku, sixoxa ngeenzuzo ze-HPMC kunye ne-MHEC kwiimveliso zodaka ezomileyo.
1. Ukugcinwa kwamanzi
Enye yeenzuzo eziphawulekayo ze-HPMC kunye ne-MHEC kwiimveliso zodaka ezinomxube owomileyo kukugcinwa kwamanzi.Ezi cellulose ethers zinokubamba izixa ezikhulu zamanzi kwaye ziwathintele ekubeni abe ngumphunga ngokukhawuleza.Oku kubalulekile kumxube owomileyo wodaka, odinga ukufakwa rhoqo kwamanzi ukuze usebenze ngokugqibeleleyo.I-HPMC kunye ne-MHEC basebenza ngokwenza ifilimu ebhityileyo ejikeleze amasuntswana odaka, obambezela ukuphuphuma kwamanzi.Ngenxa yoko, udaka luhlala lusetyenziswa ixesha elide, lunciphisa ithuba lokuqhekeka kunye nokwandisa ibhondi.
2. Ukuphucula ukubambelela
Iimveliso zodaka ezixubeneyo ezomileyo zisebenzisa i-HPMC kunye ne-MHEC zinokunamathela okungcono kunemveliso yodaka eyomileyo ngaphandle kwe-cellulose ether.I-HPMC kunye ne-MHEC zineempawu ezintle zokubambelela, ziqinisekisa ukuba udaka lunamathela kwi-substrate kwaye luhlala luhlala.Zikwanayo neplastiki efana nencangathi encamathelayo etyebisa udaka kwaye yenza kube lula ukuyifaka.Ezi zakhiwo zenza ukuba i-HPMC kunye ne-MHEC zilungele usetyenziso oluthe nkqo apho umxhuzulane utsala udaka ukuya eludongeni.
3. Ukunyuka kokuqina
I-HPMC kunye ne-MHEC kwiimveliso zodaka ezomileyo zikwanyusa ukuqina kwemveliso yokugqibela.I-cellulose ethers isebenzisana ne-samente kunye nezinye izithako ukuze zenze izakhiwo ezizinzileyo neziqinileyo.Udaka oluveliswayo alufanelwanga kukuqhekeka, ukucutheka kunye nezinye iindlela zokuwohloka.Ukongeza, i-HPMC kunye ne-MHEC zenza udaka luxhathise emanzini kunye nezinye izinto, ziqinisekisa ubomi bayo benkonzo ende.
4. Ukuphucula ukusebenza
Iimveliso zodaka ezixutyiweyo ezine-HPMC kunye ne-MHEC zinokusebenza okugqwesileyo kunye nokuguquguquka.Ukusebenza kakuhle kwezi cellulose ethers kuthetha ukuba udaka kulula ukuxuba, ukusetyenziswa kunye nokugudiswa.Bakwabonelela ngokuguquguquka okugqwesileyo, ukuvumela udaka ukuba lwande kwaye lube nesivumelwano ngaphandle kokuqhekeka okanye ukuphulukana nesidima salo sokwakheka.Oku kuguquguquka luncedo ngakumbi kwiindawo apho izinto zokwakha zibonakaliswe ekuguquguqukeni kweqondo lokushisa okanye ezinye iindlela zoxinzelelo.
5. IiNdawo eziNtonisiweyo
Xa ifakwe kwi-dry-mix-mix mortars, i-HPMC kunye ne-MHEC inika iimpawu ezikhethekileyo zesicatshulwa.I-cellulose ethers yenza ukuthungwa okugudileyo, okukhrimu okwandisa i-aesthetics yodaka.Oku kuthungwa kwenza ukuba udaka lusebenze lula ngenxa yokuba aluyi kubamba okanye ludibanise.Ukuze ukubonakala kwemveliso yodaka eyomileyo egqityiweyo ifana kwaye intle.
6. Kulula ukufaka isicelo
Enye inzuzo ye-HPMC kunye ne-MHEC kwiimveliso zodaka oluxubeneyo oluxubekileyo kukulula kwesicelo.Ezi ether ze-cellulose kulula ukuzixuba kwaye zisetyenziswe kwaye akukho lwazi lukhethekileyo lokusebenzisa.Iikontraka zinokufaka udaka ngokusebenzisa iindlela zesintu ezifana neebhrashi, iirola, iitrowel okanye imipu yokutshiza.Oku kwenza udaka oluxubeneyo olune-HPMC kunye ne-MHEC lube lolona khetho lubalaseleyo kubakhi abaziingcali kunye ne-DIYers ngokufanayo.
7. Ukusebenza kweendleko
Iimveliso zodaka ezinomxube owomileyo eziqulethe i-HPMC kunye ne-MHEC nazo azibizi kakhulu.Ezi ether ze-cellulose ziyafikeleleka kwaye zifuna kuphela isixa esincinci ukufezekisa umphumo oyifunayo.Ukongeza, i-HPMC kunye ne-MHEC zivumela inkunkuma encinci, njengoko udaka luhlala lunamanzi ixesha elide.Ngenxa yoko, akukho mfuneko encinci yokusebenza kwakhona okanye ukulungiswa, ukunciphisa iindleko zezinto eziphathekayo.
Ukusetyenziswa kwe-HPMC kunye ne-MHEC kwiimveliso zodaka ezomileyo zibonelela ngeenzuzo ezininzi kushishino lokwakha.Ezi cellulose ethers zandisa ukugcinwa kwamanzi, ukunamathela, ukuqina, ukuqhubekeka, ukuthungwa kunye nokulula kokusetyenziswa.Ngaphezu koko, zibiza iindleko, zibenza babe yindlela ekhangayo kubakhi kunye nabaninimzi.Ke ngoko, ukwamkelwa kwezi ethers zeselulosi kwimveliso yodaka oluxubeneyo owomileyo kunokwenzeka ukuba kuqhubeke ukukhula kwiminyaka ezayo njengoko abakhi befuna ukwenza izinto ezihlala ixesha elide nezithembekileyo.
