Izici:
① Ngokugcinwa kahle kwamanzi, ukujiya, i-rheology nokunamathela, ukukhetha kokuqala kwempahla eluhlaza yokuthuthukisa ikhwalithi yezinto zokwakha nezinto zokuhlobisa.
②Ukusetshenziswa okubanzi: ngenxa yamabanga aphelele, kungasetshenziswa kuzo zonke izinto zokwakha eziyimpushana.
③Isilinganiso esincane: 2-3 kg ngethani lezinto zokwakha eziyimpushana ngenxa yekhwalithi ephezulu.
④ Ukumelana okuhle kwezinga lokushisa eliphezulu: izinga lokugcinwa kwamanzi lemikhiqizo evamile ye-HPMC lizokwehla ngokunyuka kwezinga lokushisa. Ngokuphambene, imikhiqizo yethu ingenza udaka lube nezinga eliphezulu lokugcinwa kwamanzi lapho izinga lokushisa lifinyelela ku-30-40°C. Ukugcinwa kwamanzi okuzinzile ngisho nasezingeni eliphezulu lokushisa amahora angama-48.
⑤Ukuncibilika okuhle: ekamelweni lokushisa, engeza amanzi bese ugoqa cishe imizuzu emi-5, yiyeke ihlale imizuzu embalwa, bese uyanyakaza ukuze incibilike. Ukuqedwa kusheshiswa ku-PH8-10. Isixazululo sibekwe isikhathi eside futhi sinokuzinza okuhle. Ezintweni zokuxuba ezomile, ijubane lokuhlakazeka nokuqedwa emanzini lihle kakhulu.
Indima ye-HPMC kudaka olomile lwempuphu
Kudaka olomile lwempuphu, i-methyl cellulose ether idlala indima yokugcina amanzi, ukuqina nokuthuthukisa ukusebenza kokwakhiwa. Ukusebenza kahle kokugcinwa kwamanzi kuqinisekisa ukuthi udaka ngeke lubangele ukugaywa kwesihlabathi, impushana kanye nokunciphisa amandla ngenxa yokushoda kwamanzi kanye nokungaphelele kukasimende; umphumela wokujiya uthuthukisa kakhulu amandla esakhiwo sodaka olumanzi, futhi ukwengezwa kwe-methyl cellulose ether ngokusobala kungathuthukisa i-viscosity emanzi yodaka olumanzi, futhi ibe nokunamathela okuhle kuma-substrates ahlukahlukene, ngaleyo ndlela kuthuthukise ukusebenza kodaka olumanzi odongeni futhi kunciphise imfucuza.
Ngokuvamile, ukuphakama kwe-viscosity, kuba ngcono umphumela wokugcina amanzi. Kodwa-ke, ukuphakama kwe-viscosity, ukuphakama kwesisindo samangqamuzana e-MC, futhi ukuncibilika kwayo kuzoncishiswa, okungaba nomthelela omubi emandleni nokusebenza kokwakhiwa kodaka. Ukuphakama kwe-viscosity, kusobala kakhulu umphumela wokuqina odongeni, kodwa awulingani ngokuqondile. Ukuphakama kwe-viscosity, i-viscous yodaka olumanzi luyoba lukhulu. Ngesikhathi sokwakhiwa, kubonakala njengokunamathela ku-scraper nokunamathela okuphezulu ku-substrate. Kodwa akusizi ukwandisa amandla esakhiwo sodaka olumanzi ngokwalo.
Izakhiwo zomzimba namakhemikhali:
1. Ukubukeka: impushana emhlophe noma emhlophe.
2. Usayizi we-particle: 80-100 mesh izinga lokuphasa likhulu kuno-98.5%; Izinga lokuphasa nge-80 mesh ngu-100%.
3. Izinga lokushisa le-Carbonization: 280-300°C
4. Ukuminyana okubonakalayo: 0.25-0.70/cm3 (imvamisa cishe ku-0.5/cm3), amandla adonsela phansi athize 1.26-1.31.
5. Izinga lokushisa lokushintsha umbala: 190-200°C.
6. Ukushuba kobuso: Isixazululo esingu-2% samanzi ngu-42-56dyn/cm3.
7. Incibilika emanzini nakwezinye izincibilikisi, njenge-ethanol/amanzi, i-propanol/amanzi, i-trichloroethane, njll. ngezilinganiso ezifanele. Izixazululo ezinamanzi zisebenza phezulu. Ukucaca okuphezulu nokusebenza okuzinzile. Ukucaciswa okuhlukile kwemikhiqizo kunamazinga okushisa e-gel ahlukene, futhi ukuncibilika kuyashintsha nge-viscosity. I-viscosity ephansi, i-solubility enkulu. Ukucaciswa okuhlukile kwe-HPMC kunomehluko othile ekusebenzeni, futhi ukuhlakazwa kwe-HPMC emanzini akuthintwa inani le-pH.
8. Ngokuncipha kokuqukethwe kwe-methoxyl, iphuzu lejeli liyakhula, ukuncibilika kwamanzi kwe-HPMC kuncipha, nomsebenzi ongaphezulu nawo uyancipha.
9. I-HPMC iphinde ibe nezici zekhono lokuqina, ukumelana nosawoti, okuqukethwe komlotha ophansi, ukuzinza kwe-PH, ukugcinwa kwamanzi, ukuzinza kwe-dimensional, ukwakheka kwefilimu okuhle kakhulu, kanye nohlu olubanzi lokumelana nama-enzyme, ukuhlakazeka nokubumbana.
Inhloso eyinhloko:
1. Imboni yezokwakha: Njenge-ejenti egcina amanzi kanye ne-retarder kasimende, ingenza udaka lumpompeke. Isetshenziswa njenge-binder ku-plaster, i-plaster, i-putty powder noma ezinye izinto zokwakha ukuze kuthuthukiswe ukusabalala nokwandisa isikhathi somsebenzi. Ingasetshenziswa njenge-paste tile, imabula, umhlobiso wepulasitiki, ukuqinisa ukunamathisela, futhi inganciphisa inani likasimende. Ukusebenza kokugcina amanzi kwe-HPMC kuvimbela udaka ekuqhekekeni ngenxa yokoma ngokushesha ngemva kokufakwa, futhi kuthuthukisa amandla ngemva kokuqina.
2. Imboni yokukhiqiza i-Ceramic: Isetshenziswa kakhulu njengesibophezelo ekwenzeni imikhiqizo yobumba.
3. Imboni yokumboza: Isetshenziswa njenge-thickener, dispersant kanye ne-stabilizer embonini yokugqoka, futhi inokuhambisana okuhle emanzini noma ku-organic solvents. Ingasetshenziswa kusikhiphi sikapende.
4. Ukuphrinta kukayinki: Isetshenziswa njenge-thickener, dispersant and stabilizer embonini ye-inki, futhi inokuhambisana okuhle emanzini noma izincibilikisi zemvelo.
5. Ipulasitiki: isetshenziswa njengokwakha i-ejenti yokukhulula, isithambile, isithambiso, njll.
6. I-Polyvinyl chloride: Isetshenziswa njenge-disperant ekukhiqizeni i-polyvinyl chloride, futhi iyi-ejenti eyinhloko eyisizayo yokulungiselela i-PVC ngokumiswa kwe-polymerization.
7. Abanye: Lo mkhiqizo futhi usetshenziswa kakhulu esikhumbeni, emikhiqizweni yephepha, ekugcinweni kwezithelo nemifino kanye nezimboni zendwangu.
Indlela yokuqeda nokusebenzisa:
1. Thatha u-1/3 noma u-2/3 yenani elidingekayo lamanzi ashisayo bese uwashisisa aze abe ngaphezu kuka-85°C, engeza i-cellulose ukuze uthole udaka lwamanzi ashisayo, bese ufaka amanzi abandayo asele, qhubeka ugqugquzela, bese upholisa amanzi. ingxube ewumphumela.
2. Yenza utshwala bukamama obufana nephalishi: qala wenze utshwala be-HPMC kamama ngokugxila kakhulu (indlela iyafana nengenhla ukuze udaka), engeza amanzi abandayo bese uqhubeka ugqugquzela kuze kube sobala.
3. Ukusetshenziswa okuxubile okomile: Ngenxa yokuhambisana okuhle kakhulu kwe-HPMC, ingaxutshwa kalula nosimende, i-gypsum powder, i-pigments nama-fillers, njll, futhi ifinyelele umphumela oyifunayo.
Izinyathelo zokupakisha, zokugcina nezokuthutha:
Ipakishwe ngepulasitiki yephepha noma imiphongolo yekhadibhodi ehlanganiswe nezikhwama zepulasitiki ze-polyethylene, isisindo senetha isikhwama ngasinye: 25kg. Ivalwe ukuze igcinwe. Vikela elangeni, emvuleni nasemswakameni ngesikhathi sokulondoloza nokuhamba.
