Iingubo zokwaleka zidlala indima ebalulekileyo ekukhuseleni nasekuphuculeni iindawo ezahlukeneyo, ukusuka kwiindonga kunye neesilingi ukuya kwii-substrates zetsimbi kunye nomsebenzi womthi.Ukufezekisa ukusebenza kakuhle kwizicelo zokugquma kubalulekile kwiingcali kumashishini okwakha nokupeyinta.Esinye isithako esibalulekileyo esitshintshe intsimi yiHydroxyethyl Methyl Cellulose (HEMC).Kweli nqaku, siza kuphonononga izibonelelo zokusebenzisa i-HEMC kwiingubo kunye nendlela enceda ngayo ukufezekisa ukusebenza okukhethekileyo, okukhokelela ekugqityweni okuphezulu kunye nokuhlala ixesha elide.
Ukuqonda i-Hydroxyethyl Methyl Cellulose (HEMC):
I-HEMC yi-ether yeselulosi enyibilikayo enezinto ezininzi kunye ne-ether ephuma kwimicu yezityalo zendalo.Isetyenziswa ngokubanzi kwizinto ezahlukeneyo zokwakha kunye neengubo ngenxa yeempawu zayo ezizodwa, kubandakanywa nokugcinwa kwamanzi aphezulu, amandla okuqina, kunye neempawu ezibalaseleyo zokwenza ifilimu.Ikhono le-HEMC lokuguqula i-rheology yeengubo yenza ukuba ibe yinto efunekayo ekufezekiseni ukusebenza kakuhle.
Ukomelezwa kokuSebenza kwizicelo zoKugquma:
Xa yongezwa kwiingubo, i-HEMC inika ukusebenza okuphawulekayo kunye nokulula kwesicelo.Iimpawu zayo ezigqwesileyo zokugcina amanzi zenza ukuba ii-coatings zigcine ukuhambelana kwazo kwaye zithintele ukomisa kwangaphambi kwexesha, ukunika abapeyinti kunye nabafake izicelo ixesha elaneleyo lokusebenza kwiindawo ezinkulu ngaphandle kokukhathazeka malunga nesicelo esingalinganiyo okanye ukubethelwa kwebrashi ebonakalayo.
Ukufezekisa uKutyabeka okugudileyo kunye nokufanayo:
Ubuchule bokutyeba be-HEMC buvumela ukuba ilawule ukuhamba kunye nokuxhathisa kwe-sag yeengubo, iqinisekisa ukuba ipeyinti ibambelela ngokulinganayo kwiindawo ezithe nkqo ngaphandle kokubaleka okanye ukuvuza.Olu phawu lunenzuzo ngakumbi xa ugquma iindonga, njengoko lukhokelela ekugqityweni okugudileyo kunye nokufana okufanayo, nakwimigangatho eqingqiweyo.
Ukuphuculwa kokuncamathela kunye noKuhlala ixesha elide:
Enye yeengxaki eziphambili kwizicelo zokugqoka kukuqinisekisa ukubambelela ngokuqinileyo kwi-substrate kunye nokuqina kwexesha elide.I-HEMC idlala indima ebalulekileyo ekuphuculeni iimpawu zokubambelela kwiingubo, ukukhuthaza ukudibanisa okungcono phakathi kwepeyinti kunye nomphezulu.Oku kukhokelela kwiingubo ezikwazi ukumelana nokuqhekeka, ukuxobula, kunye nokuqhawula, ukuqinisekisa inkangeleko ehlala ihleli kwaye ekhangayo.
Ukuhambelana neeNkqubo zokuBika ezohlukeneyo:
I-HEMC iyahambelana noluhlu olubanzi lweenkqubo zokugquma, kubandakanywa i-water-based, latex, kunye nepeyinti ye-acrylic.Ukuguquguquka kwayo kuyenza ilungele iindlela ezahlukeneyo zokusebenzisa, njengokuxukuxa, ukuqengqeleka, kunye nokutshiza, kuyenza ibe sisithako esibalulekileyo kwiingcali ezifuna iziphumo zokwaleka ezingaguqukiyo nezithembekileyo.
Isisombululo Esihambelana nokusiNgqongileyo:
Enye inzuzo yokusebenzisa i-HEMC kwiingubo yindalo yayo ehambelana nokusingqongileyo.Njenge-ether ye-cellulose evela ngokwendalo, iyabola kwaye ibeka ingozi encinci kokusingqongileyo.Oku kwenza kube lukhetho olukhethwayo kwiiprojekthi zokwakha ezikhathalela indalo kunye nezicelo zokugquma.
Ukuqukumbela, i-Hydroxyethyl Methyl Cellulose (HEMC) iye yavela njengenguqu yomdlalo kwizicelo zokugqoka, inika uluhlu olubanzi lweenzuzo kwiingcali kumashishini okwakha kunye nokudweba.Ukusuka ekomelezeni ukusebenza kunye nokufezekisa ukugqiba okugudileyo ukuya ekuphuculeni ukubambelela kunye nokuqina, i-HEMC ingqina ukuba sisithako esiyimfuneko ekufezekiseni ezona ziphumo zokwambatha.Njengoko imfuno yomgangatho ophezulu yokugqoka iqhubeka ikhula, ukuqonda ukusetyenziswa kwe-HEMC kwiingubo kunokukhokelela kwiziphumo ezikhethekileyo kunye nabathengi abanelisekile.
