I-Diatom yodaka yokuhlobisa odongeni iyinto engokwemvelo futhi enobungani bemvelo yokuhlobisa udonga lwangaphakathi, esetshenziselwa ukufaka isithombe sangemuva nopende we-latex.Inokuthungwa okucebile futhi yenziwe ngezandla ngabasebenzi.Kungaba bushelelezi, kuntekenteke, noma kube kubi futhi kube ngokwemvelo.Udaka lwe-Diatom luthambile futhi lunezimbotshana, futhi ukwakheka kwalo okuhlukile "kwesihluzo samangqamuzana" kunquma ukukhangiswa kwalo okunamandla kakhulu nemisebenzi yokushintshisana kwamangqamuzana.Iwumthombo ongangcoli, onempilo, ohambisana nemvelo, kanye nohlaza.
Ihlakazeka kabushai-polymerimpushanainikeza amandla okubopha afanele, ukuguquguquka, ukumelana namabala, izakhiwo ezingangeni manzi neziphefumulayo zodaka lwe-diatom zokuhlobisa izinto zodonga.Namuhla, udaka oluningi lwe-diatom lusetshenziselwa ukuhlobisa udonga.Nakuba udaka lwe-diatom lumba eqolo, aluyigcini kakhulu imvelo.Ngakho-ke, lapho ukhethaezihlakazeka kabushaimpushana, udinga ukukhetha amandla aphezulu, i-powder ekwazi ukuphinde iphinde iphinde ibe nobungane imvelo, engandisa amandla nokumelana nodonga.Kuyadingeka ukwengeza i-polymer powder ehlakazeka kabusha odakeni lwe-diatom, olungathuthukisa kakhulu amandla okubopha nokuhlangana kwezinto.
Izinto ezakha ifilimu ziyisici esiyinhloko esithinta izakhiwo ezingokomzimba nokusebenza kwemvelo kokumbozwa kodaka lwe-diatom.Isetshenziswa njengento yokwenza ifilimu yodaka lwe-diatom, ukumboza kudinga ukufinyeleleka komoya okuphezulu, amandla okubopha, ukumelana kwamanzi, ukuguquguquka kanye nokuqukethwe okuphansi kwe-VOC.Lapho i-polymer ihlangana namanzi, ama-molecule amanzi akha amabhondi e-hydrogen no-O-, -S-, -N-, njll. ku-polymer, okuthuthukisa umthamo wokumunca umswakama.Uma kukhulu ukugqama kwe-polymer, amandla okumunca amanzi anamandla, kuyilapho amandla okumunca umswakama wama-polymer angewona ama-polar acishe abe ziro.Uhlobo nenani lamaqembu asezindaweni ezishisayo echungechungeni lwamangqamuzana anquma umthamo wokumunca umswakama;amandla okumunca umswakama nawo ahlobene nesakhiwo se-polymer.Uma ama-athomu ejwayeleke kakhulu, anciphisa ukumuncwa komswakama;ukuminyana ifilimu kuzophinde kuthinte umthamo ukumuncwa umswakama enamathela.Okungcono ukuqhubeka, ifilimu iminyene, iyancipha ukungena komswakama;lapho ukuqhubeka kubi kakhulu, kuqina isenzo se-capillary, sivumela kakhulu ukungena kwama-molecule wamanzi.
Indimaskwei-latex powder ehlakazeka kabushaodakeni lwe-diatom:
1. I-latex powder ehlakazeka kabusha yenza ifilimu ngemva kokuhlakazwa futhi isebenza njenge-ejenti eqinisayo njenge-adhesive yesibili;
2. I-colloid evikelayo imuncwa isistimu yodaka (ngeke ibhujiswe ngamanzi noma "ihlakazwe okwesibili" ngemva kokwakhiwa kwefilimu;
3. I-polymer eyenza ifilimu isakazwa kulo lonke uhlelo njengento yokuqinisa, ngaleyo ndlela ikhulise ukuhlangana;i-latex powder ehlakazeka kabushayin ai-powder adhesiveeyenziwe nge-emulsion ekhethekile (i-polymer) isifutho-omisiwe.Le powder ingaphinde ihlakazwe ngokushesha ukuze yenze i-emulsion ngemva kokuxhumana namanzi, futhi inezindawo ezifanayo njenge-emulsion yokuqala, okungukuthi, ingakha ifilimu ngemva kokuba amanzi eqhuma.Le filimu inokuguquguquka okuphezulu, ukumelana nesimo sezulu esiphezulu futhi imelana nezinhlobonhlobohukunamathela ku-substrate.
4. Njenge-organic gelling material, i-latex powder ekhethekile yodaka lwe-diatom ingathuthukisa ukunamathela kwezinto zokuhlobisa udaka lwe-diatom, ukwandisa ukuguquguquka, ukunciphisa ukuqhekeka, nokwandisa ukuhlangana.
I-Special Redispersiblei-lateximpushana yodaka lwe-diatom kufanele ingabi nephunga, ithuthukise amandla okubopha phakathi kodaka lwe-diatom kanye nongqimba lwesisekelo, ithuthukise ukuhlangana kwayo, ithuthukise izinga lokushisa layo nokumelana nomswakama, futhi yenze udaka lwe-diatom lube nokuguquguquka okuthile ukuvimbela ukubunjwa okuhlukahlukene.ukuqhekeka, kuyilapho kungaphazamisi izakhiwo ezilawula ukukhangiswa kanye nomswakama wodaka lwe-diatom.
