kuqala. Okokuqala qonda ukuthi yinii-polymer powder ehlakazeka kabusha.
Izimpushana ze-polymer ezihlakazekayo ama-polymer ayimpuphu akhiwe nge-emulsion ye-polymer ngokusebenzisa inqubo efanele yokumisa isifutho (kanye nokukhethwa kwezithasiselo ezifanele). I-polymer powder eyomile iphenduka i-emulsion lapho ihlangana namanzi, futhi ingaphinda iphelelwe amanzi ngesikhathi sokuhlangana kanye nenqubo yokuqina kodaka, ukuze izinhlayiya ze-polymer zakhe isakhiwo somzimba we-polymer odakeni, olufana nenqubo yesenzo sodaka. i-emulsion ye-polymer, engathuthukisa udaka lukasimende. umphumela wocansi. I-emulsion powder dry modified mortar ibizwa ngokuthi i-dry powder mortar (eyaziwa nangokuthi udaka olomile oluxubile, udaka olomile oluxubile). Njengoba i-powder eyomile ayidingi ukucabangela ukubunjwa kwe-emulsion nokuzinza njengama-emulsions e-polymer, inani elincane le-admixture lingenza udaka lufinyelele izakhiwo ezifiselekayo, futhi lunezinzuzo zokupakisha okulula, ukugcinwa, ukuthutha kanye nokuhlinzeka kune-emulsions, i-antifreeze kanye no-cha. ukukhula kwesikhunta, Inkinga yamabhaktheriya aphilayo, kanye nenzuzo yokuthi ingenziwa umkhiqizo onengxenye eyodwa ngokupakishwa okuxubile okufana nosimende nesihlabathi, futhi ingasetshenziswa ngemva kokwengeza amanzi.
Uma ufaka isicelo, hlanganisa futhi upakishe isihlabathi, usimende, i-emulsion powder eyomile nezinye izithasiselo ezisizayo kusengaphambili, futhi udinga kuphela ukwengeza inani elithile lamanzi ngesikhathi sokwakhiwa kwendawo ukuze wenze udaka olomile lwempuphu ngokusebenza okungcono. Umnyombo wokukhiqizwa kwe-emulsion powder eyomile ukuthi izinhlayiya ze-polymer ngemva kokuhlakazwa kabusha kwe-latex powder zibonisa usayizi wezinhlayiyana noma ukuhlakazeka kosayizi wezinhlayiyana okufana nalokho kwezinhlayiya ze-emulsion polymer yasekuqaleni. Inani elithile le-colloid yokuzivikela njenge-polyvinyl alcohol kufanele yengezwe ku-emulsion, ukuze i-latex powder ingaphinde ihlakazeke ibe yi-emulsion lapho ithintana namanzi. Kuphela nge-dispersibility enhle lapho i-latex powder ingafinyelela umphumela omuhle kakhulu. . I-polymer powder ehlakazeka ngokuvamile iyimpushana emhlophe. Izithako zayo zihlanganisa:
I-polymer resin: Itholakala engxenyeni ewumgogodla wezinhlayiya ze-polymer powder, futhi iyingxenye eyinhloko yempushana ye-polymer ehlakazeka kabusha.
Okungeziwe (kwangaphakathi): kanye ne-resin, idlala indima yokuguqula i-resin. Izithasiselo (zangaphandle): Izinto ezengeziwe zengezwa ukuze kuqhutshekwe nokwandisa ukusebenza kwempushana ye-polymer ehlakazekayo.
I-protective colloid: ungqimba lwe-hydrophilic material esongwe phezu kwezinhlayiya ze-latex powder ezihlakazeka kabusha, i-colloid evikelayo yempushana ye-latex ehlakazeka kakhulu i-polyvinyl alcohol.
I-Anti-caking agent: i-fine mineral filler, esetshenziselwa ikakhulukazi ukuvimbela impushana yerabha ukuthi igwenywe ngesikhathi sokugcinwa nokuthuthwa kanye nokwenza lula ukugeleza kwempushana yerabha (elahlwa ezikhwameni zamaphepha noma amathangi.)
Ungayibona kanjani ikhwalithi ye-latex powder ephinda ihlakazeka?
Indlela 1, indlela yomlotha
Thatha inani elithile le-latex powder elihlakazeka kabusha, ulibeke esitsheni sensimbi ngemva kokukala, lishise lize lifike kuma-degree angaba ngu-500, ngemva kokucwilisa ekushiseni okuphezulu kwama-degrees angu-500, lipholile ekamelweni lokushisa, bese ulinganisa futhi. Isisindo esincane nekhwalithi enhle.
Indlela yesibili, indlela yokuqeda
Thatha inani elithile lempushana ye-latex ehlakazeka kabusha bese uyincibilikisa izikhathi ezi-5 ubukhulu bamanzi, ugovuze kahle futhi uyivumele ime imizuzu emi-5 ngaphambi kokuyibuka. Empeleni, ukufakwa okuncane okuhlala ongqimbeni olungezansi, kuba ngcono ikhwalithi yempushana ye-polymer ehlakazeka kabusha. Le ndlela ilula futhi kulula ukuyenza.
Indlela yesithathu, indlela yokwenza ifilimu
Thatha ikhwalithi ethile yempushana ye-latex ehlakazeka kabusha, uyihlakaze izikhathi ezi-2 emanzini, uyixube ngokulinganayo, uyeke ime imizuzu emi-2, uyigoqe futhi, uthele isixazululo engilazini ehlanzekile eyisicaba, bese ubeka ingilazi endaweni enomthunzi. . Susa lapho somile ngokuphelele. Bheka ifilimu ye-polymer esusiwe. Ukucaca okuphezulu kanye nekhwalithi enhle. Bese udonsa ngokulingene, ngokunwebeka okuhle kanye nekhwalithi enhle. Ifilimu yabe isinqunywa ibe yimichilo, icwiliswa emanzini, futhi yabonwa ngemva kosuku olu-1, ikhwalithi yefilimu yayincibilika kancane emanzini. Le ndlela inenhloso eyengeziwe
