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 ibe ingxenye eyodwa yomkhiqizo ngokupakishwa kwengxube elungile njengosimende kanye isihlabathi, 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
