Okokuqala, ibanga le-glue yokwakha kufanele libheke izinto zokusetshenziswa. Isizathu esiyinhloko sokubekwa kwe-glue yokwakha kungukungalingani phakathi kwe-acrylic emulsion ne-hpdroxypropylylym methylcellulose (HPMC). Okwesibili, ngenxa yesikhathi sokuthengisa esanele; Kukhona nokusebenza kahle kokuqina kwe-glue yokwakha. Ekwi-glue yokwakha, kufanele usebenzise i-Hydroxypropprosels esheshayo (HPMC), ngoba i-HPMC ihlakazeka emanzini kuphela, ayichithwa ngempela. Ngemuva kwemizuzu engaba mi-2, ukubonakala koketshezi kukhuphuke kancane, kukhiqiza isixazululo esibonakalayo se-viscous colloidal ngokuphelele. Imikhiqizo eshisayo ehlekisayo, lapho ivezwa emanzini abandayo, ingasabalalisa ngokushesha emanzini abilayo bese inyamalala emanzini abilayo. Lapho amazinga okushisa ehla emazingeni okushisa athile, i-viscosity avele kancane kuze kukhiqizwe isixazululo se-colloidal esobala ngokuphelele. Umthamo onconywa kakhulu we-hydroxypropylllrpropylm methylcellulose (HPMC) kwi-glue yezokwakha ngu-2-4kg.
I-Hydroxypropyl Methylcellulose (HPMPC) inezinto eziqinile zomzimba ezinamatheli zokwakha, futhi inomphumela omuhle kakhulu wokususa isikhutha namanzi okukhiya, futhi ngeke athintwe yizinguquko kunani le-pH. I-viscosity ingasetshenziswa phakathi kuka-100,000 s no-200,000 s. Ezokukhiqiza, ukukhuphuka okuphezulu, okungcono. I-Viscosity ilingana ngaphakathi namandla okucindezela amabhondi. Ukuphakama kwento ephakeme, kwehlisa amandla acindezelayo. Ngokuvamile, ukubonakala kwama-100,000 s kufanelekile.
Hlanganisa i-CMC ngamanzi bese wenza unamathisela odaka ukuze usetshenziswe kamuva. Lapho ufaka i-CMC paste, engeza inani elithile lamanzi abandayo ethangi lokuvutha ngomshini ovusa amadlingozi. Lapho kuqalwa umshini wokuvuselela, kancane futhi ngokulinganayo ufafaze i-carboxymethyl cellulose ungene ethangini lokuvutha, bese uqhubeka nokuvusa, ukuze i-carboxymethyl cellulose namanzi athambekele ngokuphelele, futhi i-carboxymetyyl cellulose ichithiwe ngokuphelele. Lapho uqeda i-CMC, kuvame ukudingekile ukusabalalisa ngokulinganayo futhi uhlanganise ngokuqhubekayo, ukuze kungcono "ukuvimba ukuqubuka kwe-CMC ngemuva kokuthi ihlangabezane namanzi, futhi inciphise inkinga yokuchithwa kwe-CMC.
Isikhathi sokuxuba asifani nangesikhathi se-CMC ukuze sincibilike ngokuphelele. izincazelo ezi-2. Ngokuvamile, isikhathi sokuxuba sifushane kakhulu kunesikhathi se-CMC ukuze sincibilike ngokuphelele, kuya ngemininingwane. Isisekelo sokwahlulela isikhathi sokuxuba ukuthi lapho i-CMC ihlakazeka ngendlela efanayo emanzini ngaphandle kwama-lumps asobala, ukuxubana kungamiswa, ukuze ama-cmc namanzi angangena ebunyeni ngaphansi kwemibandela yedatha emile. Kunezizathu eziningana zokunquma isikhathi esidingekayo ekuchithelweni okuphelele kwe-CMC:
(1) I-CMC namanzi ahlanganiswe ngokuphelele, futhi akukho mishini yokuhlukanisa eqinile ewuketshezi phakathi kwazo;
.
(3) I-paste exubile ayinawo umbala futhi ibonakala ngokuphelele, futhi azikho izinhlayiya ezikuhambeni. Kuthatha amahora ayi-10 kuye kwangama-20 kusukela ngesikhathi lapho i-CMC ifakwa ethangini lokuvutha futhi lixutshwe namanzi kuze kube yilapho lichithwa ngokuphelele.
