Indlela yokuthuthukisa ukwakheka kwe-cellulose odongeni lokushisa eliphezulu ehlobo

Njengamanje, sekuzongena ehlobo, futhi izinga lokushisa liphakeme kakhulu, ikakhulukazi esifundeni esisenyakatho.Izinga lokushisa liphezulu futhi nomoya womile.Izinga lokushisa elingaphezulu kodonga lingafinyelela ku-60°C.Ngenxa yezinga lokushisa, i-cellulose ivame ukuba nezinkinga ezifana nokwakhiwa okungalungile kanye nokukhishwa kwempushana ngesikhathi sokwakhiwa.Isizathu esiyinhloko ukuthi ngenxa yokushisa okuphezulu kodonga, ukugcinwa kwamanzi kwe-putty akukuhle, ngakho-ke amanzi ku-putty adonswa ngokushesha noma ahwamuke odongeni, ukuze i-putty ingakwazi ukumbozwa ngokuphindaphindiwe futhi idwetshwe.Kuvela umgodi nokuxebuka.Indlela yokuthuthukisa ukugcinwa kwamanzi kwe-powdery yangaphandle odongeni putty ikakhulukazi kunezindlela ezilandelayo:

1. Khulisa inani le-cellulose ether

I-Cellulose ether inokugcinwa kwamanzi okuhle, kodwa ukusebenza kokugcinwa kwamanzi akukhuphuki ngemva kokwengezwa kwenani elithile le-cellulose ether.Ngesikhathi esifanayo, ukwanda kwe-cellulose kwandisa i-viscosity ye-putty futhi ukwakhiwa akubushelelezi.Ngaphezu kwalokho, izindleko ze-putty ziyanda.

2. Khulisa inani le-lignocellulose

I-Lignocellulose inomphumela othile wokugcina amanzi.Ukwengezwa kwe-fiber yokhuni kuthuthukisa amandla okugcina amanzi ezinto ezibonakalayo, kwenza isistimu yezinto ezibonakalayo ifakwe emanzini ngokulinganayo, futhi ingathuthukisa ukusebenza ngesikhathi esifanayo, kodwa isimiso sokugcinwa kwamanzi se-lignocellulose sihlukile kuneselulosi.Inesici sokumuncwa kwezinwele.(Ukuqhutshwa kwamanzi), kuzoba nomswakama phakathi kwe-fiber ngayinye, futhi lapho umswakama endaweni ezungezile ye-fiber ushintsha futhi uyancipha, umswakama phakathi kwemicu uzokhishwa ngokulinganayo.Isikhathi sokuvula, akulula ukuqhekeka.Kodwa-ke, ngenxa yokuthi ubukhulu be-putty odongeni lwangaphandle buncane kakhulu, ubukhulu be-scrape coating ngayinye buyi-0.5-1mm kuphela.Uma izinga lokushisa elingaphezulu lesendlalelo sesisekelo kanye nezinga lokushisa lomoya liphakeme ngokuqhathaniswa, ukusebenza kwalo kokugcinwa kwamanzi akubonakali, futhi ukusebenza okuphindaphindiwe kokwemboza kwe-scrape kuyisilinganiso.

3. Khulisa inani le-polymer

Ezindongeni ezine-putty encane, umoya owomile kanye nezinga lokushisa eliphezulu, ukwandisa inani le-polymer kungenye yezindlela ezingcono zokwenza i-putty ibe nezindawo zokukhuhla ngokuphindaphindiwe, kodwa intengo ye-latex powder ephindwe kabusha iphakeme kakhulu, inani elikhulu lizokhula kakhulu. izindleko ze-putty.Ingase futhi idlale indima engcono ngokungeza inani elincane le-polyvinyl alcohol powder, kodwa i-viscosity ye-polyvinyl alcohol powder inkulu kakhulu, ezothinta ukusebenza, futhi impahla ye-sanding ye-putty ayilungile..

4. Engeza i-polymer lubricant

Ngokuhlolwa, kubhekwa ukuthi kuyisinqumo esingcono ukwengeza i-lubricant yevolumu ephezulu ku-putty yangaphandle yodonga endaweni yokushisa okuphezulu ehlobo.I-lubricant ingeyenhlanganisela ye-polymer, futhi i-lubricant ye-rheological ihloselwe kakhulu ukuthuthukisa ukusebenza kokwakhiwa ohlelweni olusekelwe kusimende.Isikhathi esivulekile nokusebenza okungaguquki.Khulisa ukusebenza kanye nokumelana nokucwila kodaka, amapulasi, ama-renders, ama-plaster kanye nama-adhesives futhi ivimbele ukuhlukaniswa kukasimende ozilinganisa.Isizathu sokugcinwa kwamanzi ukuthi kunenombolo enkulu yamaqembu asebenzayo e-hydrophilic ku-chain yayo yamangqamuzana.Endabeni yokukhuhla okuphindaphindiwe nokugcoba, ngeke kulahlekelwe amanzi, kunokusebenza okuvelele kokugcinwa kwamanzi, futhi inokuqina kanye ne-thixotropy ngesikhathi esifanayo, okwenza ukwakhiwa kube bushelelezi futhi kungathatha ingxenye ye-cellulose, kodwa intengo yayo i-cellulose ether kuphela, futhi umthamo wayo ngu-0.1-0.2%., iyinto engabizi kakhulu, uma isetshenziswa kanye ne-cellulose ether, i-lignocellulose, ne-latex powder ehlakazeka kabusha, umphumela uzoba ngcono.
