Indlela yokwenza i-polymer powder evuselelayo (RDP)

I-Pelyperble Pelmer Powder (RDP)Ingabe i-polymer powder ephezulu ye-polymer, evame ukwenziwa nge-polymer emulsion ngokuchomisa isifutho. Inempahla yokuhlehlisa amanzi futhi isetshenziswa kabanzi ekwakhiweni, ukumboza, izinamathiseli nakwezinye izinkambu. Indlela yokusebenza kwe-polymer powder (RDP) itholakala ngokuyinxusa izinto ezisekelwe kusazi, ukwenza ngcono amandla okubopha, kanye nokwenza ngcono ukusebenza kokwakha.

1. Ukwakheka okuyisisekelo nezakhiwo ze-polymer powder powder (RDP)

Ukwakhiwa okuyisisekelo kwe-polymer powder (RDP) yi-polymer emulsion, okuvame ukuvezwa ama-monomer anjenge-acrylate, ethylene, kanye ne-vinyl acetate. Lawa ma-polybecu ase-polymer akha izinhlayiya ezinhle nge-emulsion polymerization. Ngesikhathi senqubo yokusoma yokufafaza, amanzi asuswa ukwakha i-amorphous powder. Lawa ma-powders angabuyiselwa emanzini ukuze akhe ukusabalalisa okuzinzile kwe-polymer.

Izici eziyinhloko ze-Redisperserble Powter Powder (RDP) zifaka:

I-solubility yamanzi nokubuyiselwa kwemali: Kungahlakazeka ngokushesha emanzini ukuze kwakheke umfaniswano we-colloid.

Izakhiwo ezibonakalayo ezithuthukisiwe: ngokungeza i-polymerble powder (RDP), amandla eBonding, amandla ashubile kanye nokumelana nomthelela kwemikhiqizo enjengezembatho kanye nodaka kwathuthukiswa kakhulu.

Ukumelana kwesimo sezulu kanye nokumelana kwamakhemikhali: Ezinye izinhlobo ze-polymer powder (RDP) zinokumelana kahle nemisebe ye-UV, amanzi kanye nokugqwala kwamakhemikhali.

Ukuthuthuka okuthuthukile kwe-Bonding Amandla Indima ebalulekile edlalwa yi-Redisperserble Powmer Powder (RDP) ezintweni ezisetshenziswayo zikasimende ukuthuthukisa amandla abo okuqinisa. Ukuxhumana phakathi kosimende unamathisela nohlelo lokuhlakazeka kwe-polymer kunika amandla izinhlayiya ze-polymer ukuze zibambelele endaweni yezinhlanzi. Ngokusebenzisa i-centructor ngemuva kokuqina, ama-molecule e-polymer athuthukisa amandla okubopha phakathi kwezinhlayiya zensimbi ngesenzo sokuzijabulisa, ngaleyo ndlela athuthukise amandla okuqinisa ama-mote.

Ukuguquguquka okuthuthukile kanye nokuvimbela ukumelana kabusha kwe-polymer powter (RDP) kungathuthukisa ukuguquguquka kwezinto zokwenziwa kosimende. Lapho izinto zokwenziwa ngosimende zimiswa futhi zilukhuni, ama-molecule e-polymer ku-cent paste angakha ifilimu ukwandisa ubulukhuni bezinto ezibonakalayo. Ngale ndlela, udaka kasimende noma ukhonkolo aluzithambekele ekuqhekekeni lapho ngaphansi kwamandla angaphandle, athuthukisa ukumelana nokuqhekeka. Ngaphezu kwalokho, ukwakheka kwefilimu ye-polymer nakho kungathuthukisa ukuvumelana nezimo zezinto zokwenziwa kosekhukhwini endaweni yangaphandle (njengoshintsho lomswakama, izinguquko zokushisa, njll.).

Ukulungisa ukusebenza kokwakha Ukungezwa kwe-glue powder evuselelayo nakho kungathuthukisa ukusebenza kokwakha kwezinto zokwenziwa kosimende. Isibonelo, engeza i-glue powder evuselelayo ukuze udaka olomile oluhlanganisiwe ungathuthukisa kakhulu ukusebenza kwawo futhi wenze inqubo yokwakha ibushelelezwe. Ikakhulu ezinqubweni ezinjengopende odongeni kanye nokunamathisela kwe-tile, uketshezi nokugcinwa kwamanzi kanye nokugcinwa kwamanzi kwe-slurry kuyathuthukiswa, kugwemeke ukwehluleka okubophayo okubangelwa ukuhwamuka kwangaphambi kwesikhathi.

Ukwenza ngcono ukumelana kwamanzi nokuqina ukwakheka kwefilimu ye-polymer kungavimbela ngempumelelo ukungena kwamanzi, ngaleyo ndlela kuthuthukise ukumelana kwamanzi okuqukethwe. Kwezinye izindawo ezinomswakama noma amanzi, ukungezwa kwama-polymers kungabambezela inqubo yokuguga kwezinto zokwakha kasimende futhi uthuthukise ukusebenza kwawo kwesikhathi eside. Ngaphezu kwalokho, ukuba khona kwama-polymers kungathuthukisa nokuphikiswa kwesithwathwa kwezinto ezibonakalayo, ukumelana nokugqwala kwamakhemikhali, njll., Futhi kwandise ukuqina kwesakhiwo sokwakha.

3. Ukusetshenziswa kwe-polymer powder (RDP) kwamanye amasimu

Udaka oluxutshwe ngodaka oluhlanganisiwe, ukwengeza i-polymer powder (RDP) evuselelwayo (i-RDP) kungathuthukisa ukunamathela, ukumelana nokuqhekeka kanye nokwenza umsebenzi wokwakha kodaka. Ikakhulu emikhakheni yohlelo lwangaphandle odongeni lokufakwa kwezinsikunga, njll. Ngaphezu kwalokho, engeza inani elifanele le-polymer powder (RDP) kwifomula yodaka exutshwe kahle ingathuthukisa kakhulu ukusebenziseka kanye nekhwalithi yokwakha yomkhiqizo.

I-Architural Coatings Redisperperfrible Powmer Powmer (RDP) ingathuthukisa ukunamathela, ukumelana namanzi, ukumelana kwesimo sezulu, njll. Yezembatho zezakhiwo, ikakhulukazi ezincetsheni eziphezulu ezinezingubo zodonga ezingaphandle nezingubo zangaphansi. Ukungeza i-polymer powder (RDP) engavuselelwa kabusha (i-RDP) ingathuthukisa ukwakheka kwayo kanye nokunamathela kwayo futhi yandise impilo yenkonzo ye-coating.

Adhesives kweminye imikhiqizo ekhethekile yokunamathela, efana nama-tile anamathela, ama-gypsum anamathela, njll.

Izinto ezingena ngaphansi kwamanzi ngezinto zokwenziwa manzi, ukungezwa kwama-polymers kungakha ungqimba lwamafilimu oluzinzile, ukuvikela impumelelo yokungena kwamanzi, futhi uthuthukise ukusebenza kwamanzi. Ikakhulu kwezinye izindawo ezifunwa kakhulu (njengezindawo ezingavikeleki ezingaphansi komhlaba, ukufakwa kwamanzi okuvikelekile, njll.), Ukusetshenziswa kwe-polymer powder (RDP) kungathuthukisa kakhulu umphumela ongavunyelwe.

Indlela yokwenzaI-RDP, ikakhulukazi ngezimpawu zayo ezihleliwe kanye nezimpawu zokwakha amafilimu, zinikeza imisebenzi eminingi ezintweni ezisetshenziselwa ukhula, njengokuthuthukisa amandla okuqinisa, ukuthuthukisa ukuguquguquka, ukuthuthukisa ukumelana kwamanzi, kanye nokwenza umsebenzi wokwakha. Ngaphezu kwalokho, kukhombisa ukusebenza okuhle kakhulu emikhakheni yodaka oluhlanganisiwe, izimbotshana zokwakha, ukunamathela, izinto ezingangeni manzi, njll. Ngakho-ke, ukusetshenziswa kwe-polymer powder (njdp) ezintweni zesimanjemanje zibaluleke kakhulu.
