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 kuketango layo lamangqamuzana. 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.
