Indima yempushana ye-latex ehlakazeka kabusha kumasimende ahlukahlukene

I-latex powder e-redispersible ingaphinde ihlakazeke ibe yi-emulsion ngemva kokuxhumana namanzi, futhi inezakhiwo ezifanayo njenge-emulsion yokuqala, okungukuthi, ifilimu ingakhiwa ngemva kokuba amanzi eqhuma. Le filimu inokuguquguquka okuphezulu, ukumelana nesimo sezulu esiphezulu kanye nokumelana nokunamathela okuhlukahlukene okuphezulu kuma-substrates. Ngaphezu kwalokho, i-hydrophobic latex powder ingenza udaka lungangeni manzi kakhulu.

Ukusetshenziswa okuyinhloko kwe-latex powder ephindwe kabusha

Impushana efakwa odongeni yangaphakathi nangaphandle, okokunamathisela okunamathayili, i-ejenti yokukhomba, i-ejenti yokusebenzelana kwempushana eyomile, udaka lwangaphandle olushisayo olufakwa ezindongeni, udaka oluzilinganisa, udaka lokulungisa, udaka lokuhlobisa, udaka olungangeni manzi lwangaphandle olushisayo oluxutshwe nodaka. Odakeni, okokuthuthukisa ukuqina, imodulus enwebekayo ephezulu kanye nobunye ubuthakathaka bodaka lukasimende lwendabuko, kanye nokunikeza udaka lukasimende ukuguquguquka okungcono namandla ebhondi eqinile, ukuze limelane futhi libambezele ukukhiqizwa kokuqhekeka kodaka lukasimende. Njengoba i-polymer kanye nodaka lwakha isakhiwo senethiwekhi esingena ngaphakathi, ifilimu ye-polymer eqhubekayo yenziwa ezimbotsheni, eqinisa ukubopha phakathi kwama-aggregates futhi ivimbele ezinye izimbotshana odakeni, ngakho udaka oluguquliwe ngemuva kokuqina lungcono kunodaka lukasimende. Kukhona ukuthuthuka okukhulu.

Indima ye-latex powder ehlakazeka kabusha odakeni ikakhulukazi yizici ezilandelayo

1 Thuthukisa amandla okucindezela kanye namandla aguqukayo odaka.

I-2 Ukwengezwa kwe-latex powder kwandisa ukunwetshwa kodaka, ngaleyo ndlela kuthuthukise ukuqina komthelela wodaka, futhi kunikeza udaka ngomphumela omuhle wokuhlakazeka kokucindezeleka.

3 Thuthukisa ukusebenza kwesibopho sodaka. Indlela yokubopha isekelwe ekukhangisweni nasekusakazeni kwama-macromolecule endaweni enamathelayo. Ngesikhathi esifanayo, i-powder yenjoloba ine-permeability ethile futhi ingena ngokugcwele ebusweni bezinto eziyisisekelo nge-cellulose ether, ukuze izakhiwo ezingaphezulu zesisekelo kanye ne-plaster entsha zisondele, ngaleyo ndlela ithuthukise i-Adsorption ikhulise kakhulu ukusebenza kwayo.

4 Yehlisa i-elastic modulus yodaka, uthuthukise ikhono lokuguquguquka futhi unciphise ukuqhekeka okwenzekayo.

5 Thuthukisa ukumelana nodaka. Ukuthuthukiswa kokumelana nokugqoka ikakhulukazi ngenxa yokuba khona kwenani elithile leglue ebusweni bodaka. I-glue powder isebenza njengesibopho, futhi isakhiwo se-omentum esakhiwe i-glue powder singadlula emigodini kanye nokuqhekeka odongeni lukasimende. Ithuthukisa isibopho phakathi kwezinto eziyisisekelo kanye nemikhiqizo kasimende ye-hydration, ngaleyo ndlela ikhulise ukumelana nokugqoka.

6 Nikeza udaka ukumelana okuhle kakhulu kwe-alkali.

7 Thuthukisa ukuhlangana kwe-putty, ukumelana okuhle kakhulu, ukumelana ne-alkali, ukumelana nokugqoka, nokuthuthukisa amandla okuguquguquka.

8 Thuthukisa ukungangeni kwamanzi kanye nokungena kwamanzi kwe-putty.

9 Thuthukisa ukugcinwa kwamanzi kwe-putty, wandise isikhathi esivulekile, futhi uthuthukise ukusebenza.

10 Thuthukisa ukumelana komthelela we-putty futhi uthuthukise ukuqina kwe-putty.

I-latex powder e-redispersible yenziwe nge-polymer emulsion ngokumisa isifutho. Ngemuva kokuxubana namanzi odakeni, i-emulsified futhi ihlakazwe emanzini ukuze iphinde yakhe i-emulsion ye-polymer ezinzile. Ngemuva kokuthi i-latex powder ehlakazeka kabusha ifakwe emulsified futhi ihlakazwe emanzini, amanzi ayahwamuka. Ifilimu ye-polymer yakhiwe odakeni ukuze kuthuthukiswe izakhiwo zodaka. Izimpushana ze-latex ezihlakazeka kabusha ezihlukene zinemiphumela ehlukene osikeni lwempushana owomile.

Izakhiwo zomkhiqizo ze-latex powder ehlakazeka kabusha

Thuthukisa amandla okugoba namandla okugoba odaka

Ifilimu ye-polymer eyakhiwe ngempushana ye-latex e-dispersible inokuguquguquka okuhle. Amafilimu akhiwa ezikhaleni nasezindaweni ezingaphezulu zezinhlayiya zodaka lukasimende ukuze akhe ukuxhumana okuvumelana nezimo. Udaka lukasimende olusindayo noluphukayo luba nokunwebeka. Udaka olungezwe ngempushana ye-latex ehlakazeka kabusha luphakeme ngokuphindwe kaningana ekuqiniseni ukumelana nokuguquguquka kunodaka olujwayelekile.

── Thuthukisa amandla okubopha nokuhlangana kodaka

Ngemuva kokuthi impushana ye-latex ehlakazeka kabusha njengesibophezelo sezinto eziphilayo kwakhiwa ibe ifilimu, ingakha amandla aphezulu okuqina kanye namandla okubopha kuma-substrates ahlukene. Idlala indima ebalulekile ekunamatheleni kodaka ezintweni eziphilayo (EPS, ibhodi legwebu elikhishwe) kanye nama-substrates angaphezulu abushelelezi. Ifilimu ye-polymer rubber powder isatshalaliswa kulo lonke uhlelo lodaka njengento yokuqinisa ukukhulisa ukuhlangana kodaka.

──Thuthukisa ukumelana komthelela, ukuqina nokumelana nokugqoka kodaka

Izinhlayiya ze-raber ze-powder zigcwalisa umgodi wodaka, ukuminyana kodaka kuyanda, futhi ukumelana nokugqoka kuyathuthukiswa. Ngaphansi kwesenzo samandla angaphandle, izokhiqiza ukuphumula ngaphandle kokubhujiswa. Ifilimu ye-polymer ingaba khona unomphela ohlelweni lodaka.

──Thuthukisa ukumelana nesimo sezulu kanye nokumelana nokuncibilika kodaka, futhi uvimbele udaka ekuqhekekeni

I-redispersible latex powder iyi-resin ye-thermoplastic ene-flexible eguquguqukayo, engenza udaka lubhekane nokushintsha kwendawo ebandayo yangaphandle neyokushisa, futhi ivimbele ngokuphumelelayo udaka ekuqhekekeni ngenxa yokushintsha umehluko wokushisa.

── Thuthukisa i-hydrophobicity yodaka futhi unciphise ukumuncwa kwamanzi

I-latex powder ehlakazeka kabusha yenza ifilimu emgodini nangaphezulu kodaka, futhi ifilimu ye-polymer ngeke iphinde ihlakazeke ngemva kokuvezwa emanzini, okuvimbela ukungena kwamanzi futhi kuthuthukise ukungakwazi ukungena. I-latex powder ekhethekile ephindwe kabusha enomphumela we-hydrophobic, umphumela ongcono we-hydrophobic.

── Thuthukisa ukusebenza kokwakhiwa kodaka&

Kunomphumela wokugcoba phakathi kwezinhlayiya ze-polymer rubber powder, ukuze izingxenye zodaka zikwazi ukugeleza ngokuzimela. Ngesikhathi esifanayo, i-powder yenjoloba inomphumela we-inductive emoyeni, inikeze ukucindezelwa kodaka futhi ithuthukise ukusebenza kokwakhiwa kodaka.
