Indima yempushana ye-latex ehlakazeka kabusha emikhiqizweni yodaka

1. Iyini imisebenzi ye-latex powder ehlakazeka kabusha odakeni?

Impendulo: I-latex powder ehlakazeka kabusha ibunjwa ngemva kokuhlakazeka futhi isebenza njenge-adhesive yesibili yokuthuthukisa isibopho; i-colloid evikelayo imuncwa uhlelo lodaka (ngeke kuthiwe izobhujiswa ngemva kokubunjwa. Noma ihlakazwe kabili); i-polymerization ebunjiwe I-resin ebonakalayo isakazwa kulo lonke uhlelo lodaka njengento eqinisayo, ngaleyo ndlela ikhulise ukuhlangana kodaka.

2. Iyini imisebenzi ye-latex powder ehlakazeka kabusha odakeni olumanzi?

Impendulo: Thuthukisa ukusebenza kokwakhiwa; ngcono fluidity; ukwandisa ukumelana ne-thixotropy kanye ne-sag; thuthukisa ukuhlangana; ukwandisa isikhathi sokuvula; thuthukisa ukugcinwa kwamanzi;

3. Iyini imisebenzi yempushana ye-latex ehlakazeka kabusha ngemva kokuba udaka selashiwe?

Impendulo: ukwandisa amandla okuqina; thuthukisa amandla okugoba; ukunciphisa i-elastic modulus; ukwandisa ukukhubazeka; ukwandisa ukuminyana kwezinto ezibonakalayo; ukwandisa ukumelana nokugqoka; ukwandisa amandla okuhlangana; Ine-hydrophobicity enhle kakhulu (engeza i-hydrophobic rubber powder).

4. Iyini imisebenzi yempushana ye-latex ehlakazeka kabusha emikhiqizweni ehlukene yodaka lwempushana eyomile?

01. I-Tile Adhesive

02. Uhlelo lwangaphandle lokufakwa kwezindonga

① Umthelela kudaka olusha
A. Nweba amahora okusebenza;
B. Ukuthuthukisa ukusebenza kokugcinwa kwamanzi ukuze kuqinisekiswe ukugeleza kukasimende;
C. Thuthukisa ukusebenza.

② Umthelela odakeni oluqinile
A. Inonamathela kahle ebhodini le-polystyrene namanye ama-substrates;
B. Ukuguquguquka okuhle kakhulu kanye nokumelana nomthelela;
C. Ukungena kahle komhwamuko wamanzi;
D. Ukuxosha kahle amanzi;
E. Ukumelana nesimo sezulu esihle.

03. Ukuzilinganisa

① Umthelela kudaka olusha
A. Siza ekuthuthukiseni ukuhamba;
B. Thuthukisa ukubumbana futhi unciphise i-delamination;
C. Yehlisa ukwakheka kwebhamuza;
D. Thuthukisa ukushelela kwendawo;
E. Gwema ukuqhekeka kusenesikhathi.

② Umthelela odakeni oluqinile
A. Thuthukisa ukumelana nokuqhekeka kokuzilinganisa;
B. Thuthukisa amandla okugoba okuzilinganisa;
C. Ukuthuthukisa ngokuphawulekayo ukumelana nokugqokwa kokuzilinganisa;
D. Khulisa ngokuphawulekayo amandla esibopho sokuzilinganisa.

04. Phuthi

① Umthelela kudaka olusha
A. Thuthukisa ukwakheka;
B. Engeza ukugcinwa kwamanzi okwengeziwe ukuze uthuthukise ukugeleza kwamanzi;
C. Khulisa ukusebenza;
D. Gwema ukuqhekeka kusenesikhathi.

② Umthelela odakeni oluqinile
A. Nciphisa imodulus enwebekayo yodaka futhi ukhulise ukumatanisa kwesisekelo;
B. Khulisa ukuguquguquka futhi umelane nokuqhekeka;
C. Thuthukisa ukumelana nokuchithwa kwempushana;
D. I-Hydrophobic noma ukunciphisa ukumuncwa kwamanzi;
E. Khulisa ukunamathela kungqimba oluyisisekelo.

05. Udaka olungangeni manzi

① Umthelela kudaka olusha:
A. Thuthukisa ukwakheka
B. Ukwandisa ukugcinwa kwamanzi futhi uthuthukise ukugeleza kukasimende;
C. Khulisa ukusebenza;

② Umthelela kudaka oluqinile:
A. Yehlisa imodulus enwebekayo yodaka futhi uthuthukise ukumatanisa kwesisekelo;
B. Khulisa ukuguquguquka, ukumelana nokuqhekeka noma ube nekhono lokuvala ibhuloho;
C. Thuthukisa ukuminyana kodaka;
D. I-Hydrophobic;
E. Khulisa amandla okubumbana.
