Ibanga leglue yokwakha yinkinga ekhathaza amakhasimende.
1. Ibanga le-adhesive yokwakha kufanele licabangele izinto zokusetshenziswa.Isizathu esiyinhloko sokwakhiwa kwesendlalelo esibophezelayo ukungahambisani phakathi kwe-acrylic emulsion ne-hydroxypropyl methylcellulose (HPMC).
2. Ngenxa yesikhathi esinganele sokuxuba;i-adhesive yokwakha nayo inenkinga yezakhiwo ezingezinhle zokuqina.Ezinamathelayo zokwakha, kubalulekile ukusebenzisa ikhofi esheshayo i-hydroxypropyl methylcellulose (HPMC) ngoba i-HPMC isanda kuhlakazwa emanzini futhi ayincibiliki ngempela.Ngemuva kwemizuzu emi-2, i-viscosity ye-liquid ikhula kancane kancane, ikhiqize isisombululo se-viscous colloidal esisobala ngokuphelele.Imikhiqizo encibilika ngokushisayo ingahlakazeka ngokushesha emanzini abilayo futhi inyamalale emanzini abilayo lapho ihlangana namanzi abandayo.Lapho izinga lokushisa lehlela ezingeni elithile lokushisa, ukuncipha kwe-viscosity kwenzeka kuze kube yilapho kukhiqizwa isisombululo se-viscous colloidal esisobala ngokuphelele.Kunconywa kakhulu ukusebenzisa i-2-4 kg ye-hydroxypropyl methylcellulose (HPMC) kuma-adhesives wokwakha.
3. Izinto ezibonakalayo ze-hydroxypropyl methylcellulose (HPMC) ekunamatheleni okwakhiwa zizinzile, umphumela wokulwa nesikhutha muhle kakhulu, futhi ngeke wonakaliswe izinguquko ku-pH value.I-viscosity ingasetshenziswa phakathi kuka-100,000 no-200,000 s, kodwa ekukhiqizeni Lapho kukhiqizwa, ukuphakama kwe-viscosity, kungcono.I-viscosity ihambisana ngokuphambene namandla acindezelayo we-adhesive.Ukuphakama kwe-viscosity, amandla okucindezela aphansi.Ngokuvamile, i-viscosity ingama-100,000s.
Manje embonini yokuhlobisa, ukusetshenziswa kwe-hydroxypropyl methylcellulose kuqine kakhulu.
Lisetshenziswa kanjani leli nani?Thatha nawe:
Ngokushesha hlanganisa i-CMC namanzi ukuze wenze ingcina efana nokunamathisela bese ubeke eceleni.Uma ufaka ukunamathisela kwe-CMC, sebenzisa i-mixer ukwengeza inani elithile lamanzi abandayo ebhodweni lezithako.Lapho i-mixer iqalwa, ufafaze kancane kancane futhi ngokulinganayo i-carboxymethylcellulose ethangini lesithako, futhi uqhubeke ushukumisa ukuze uhlanganise ngokugcwele i-carboxymethylcellulose namanzi futhi uhlakaze ngokuphelele i-carboxymethylcellulose.Lapho uhlakaza ibhodi le-tube, ngokuvamile kudingekile ukulihlakaza ngokulinganayo futhi uqhubeke uvuselela ukuze kangcono "ukuvimbela ukwakheka nokwakheka kwebhodi le-tube lapho ihlangana namanzi, ukunciphisa inkinga yokuchithwa kwebhodi le-tube" futhi kuthuthukise ukuncibilika kwebhodi le-tube. .Izinga lokuchithwa kwekomidi labaphathi.
Isikhathi sokuxuba sihlukile kunesikhathi esisithathayo ukuze i-CMC incibilike ngokuphelele.Lezi izincazelo ezimbili.Ngokuvamile, isikhathi sokuxuba sifushane kakhulu kunesikhathi sokuqedwa ngokuphelele kwe-CMC, kuye ngesimo esithile.Isikhathi sokuxuba sinqunywa ngokusekelwe kumazinga wedatha amile.Lapho i-CMC ihlakazeka ngokulinganayo emanzini ngaphandle kokuhlanganisa okusobala, ukuxuba kuyanqanyulwa ukuze kuvunyelwe i-CMC namanzi ukuthi kungene phakathi.
Kunezizathu ezimbalwa zesikhathi esidingekayo ukuze kuqedwe ngokuphelele i-CMC:
(1) I-CMC namanzi kuhlanganiswe ngokuphelele, futhi azikho izisetshenziswa zokuhlukanisa uketshezi oluqinile phakathi kwakho;
(2) Ingxube ifana futhi ibushelelezi, futhi ingaphezulu libushelelezi futhi linomanzi;
(3) Ngemva kokuxuba, ukunamathisela akunambala futhi kukhanye ngokuphelele, futhi azikho izinhlayiya ekunamathiseleni.Kuthatha amahora ayi-10 kuye kwangama-20 kusukela ngesikhathi i-CMC ifakwa kwingxube yethangi lezithako namanzi ize ichitheke ngokuphelele.
