Eminyakeni yamuva nje, kuye kwavela emakethe impushana eningi ye-resin polymer, i-polymer powder enamandla amakhulu kanye nezinye ezishibhile kakhulu ukuze zithathe indawo ye-VAE emulsion yendabuko (vinyl acetate-ethylene copolymer), eyomiswa futhi eyomisiwe. eyenziwe nge-polymer powder egaywa kabusha.Impushana ye-polymer ehlakazekile, ngakho-ke uyini umehluko phakathi kwe-resin powder ne-polymer powder ehlakazeka kabusha, ingabe i-resin powder ingangena esikhundleni se-polymer powder ehlakazeka kabusha?I-Mortar Technology Center izokuholela ekuhlaziyeni kafushane umehluko phakathi kwakho kokubili ukuze uthole inkomba yakho:
(1), i-polymer powder ehlakazeka kabusha
Njengamanje, izimpushana ze-polymer ezihlakazeka kabusha ezisetshenziswa kabanzi emhlabeni yilezi: i-vinyl acetate ne-ethylene copolymer powder (VAC/E), i-ethylene, i-vinyl chloride ne-vinyl laurate ternary copolymer powder (E/VC/VL), i-acetic acid Vinyl ester, ethylene. kanye namanoni aphezulu e-vinyl ester ternary copolymer powder (VAC/E/VeoVa), lezi zimpushana ezintathu ezihlakazeka kabusha ze-polymer zibusa yonke imakethe, ikakhulukazi i-vinyl acetate ne-ethylene copolymer powder VAC/EE, ithatha isikhundla esiphambili emkhakheni womhlaba wonke futhi imele ubuchwepheshe. izici ze-polymer powder ehlakazeka kabusha.Kuseyisixazululo esingcono kakhulu sezobuchwepheshe ngokuya ngesipiliyoni sobuchwepheshe ngama-polymers asetshenziswa ekuguqulweni kodaka:
1. Ingenye yama-polymer asetshenziswa kakhulu emhlabeni;
2. Isipiliyoni sokufaka isicelo emkhakheni wokwakha sikhulu kakhulu;
3. Ingakwazi ukuhlangabezana nezakhiwo ze-rheological ezidingwa udaka (okungukuthi, ukwakhiwa okudingekayo);
4. I-polymer resin namanye ama-monomers inezici ze-organic volatile matter (VOC) ephansi kanye negesi ephansi ecasulayo;
5. Inezici zokumelana okuhle kakhulu kwe-UV, ukumelana nokushisa okuhle nokuzinza kwesikhathi eside;
6. Ukumelana okuphezulu ne-saponification;
7. Inezinga lokushisa elibanzi kakhulu lengilazi lokushintsha (Tg);
8. Inokuxhumana okuhle kakhulu okubanzi, ukuguquguquka kanye nezakhiwo zemishini;
9. Yiba nesipiliyoni eside kakhulu sokukhiqiza amakhemikhali sendlela yokukhiqiza imikhiqizo yekhwalithi ezinzile kanye nesipiliyoni ekugcineni ukuqina kwesitoreji;
10. Kulula kakhulu ukuhlanganisa ne-colloid evikelayo (i-polyvinyl alcohol) ngokusebenza okuphezulu.
(2), inhlaka yempushana
Iningi le-polymer powder "ye-resin" emakethe iqukethe ikhemikhali i-DBP.Ungahlola ukulimaza kwalesi sakhi samakhemikhali, esithinta umsebenzi wobulili besilisa.Inani elikhulu lalolu hlobo lwempushana ye-polymer linqwabelaniswa endaweni yokugcina impahla kanye naselabhorethri, futhi linokuguquguquka okuthile.Emakethe yaseBeijing, edume ngokuchichima kwayo “kwempushana ye-polymer”, manje sekukhona “impushana ye-polymer” efakwe ezincibilikisini ezinamagama ahlukahlukene: impushana ye-polymer enamandla amakhulu, i-resin polymer powder, njll. Izici ezijwayelekile:
1. Ukuhlakazeka okumpofu, abanye bazizwa bemanzi, abanye bazizwa be-flocculent (kufanele kube into enezimbotshana njenge-sepiolite), abanye bamhlophe futhi bome kancane kodwa zisanuka kabi;
2. Inuka kakhulu;
3. Eminye imibala yengeziwe, futhi imibala evelayo njengamanje emhlophe, ephuzi, empunga, emnyama, ebomvu, njll.;
4. Inani lokwengeza lincane kakhulu, futhi inani lokwengezwa kwethani elilodwa liyi-5-12 kg;
5. Amandla okuqala mahle ngokumangalisayo.Usimende awunawo amandla ngezinsuku ezintathu, futhi ibhodi lokufakelwa lingagqwala futhi linamathele;
6. Kuthiwa ibhodi le-XPS alidingi i-ejenti yesixhumi esibonakalayo.
Ngokusebenzisa amasampula atholwe kuze kube manje, kungaphetha ngokuthi i-resin esekelwe ku-solvent ekhangiswe ngezinto ezikhanyayo ezingenalutho, kodwa umphakeli ufuna ukugwema ngamabomu igama elithi "solvent", ngakho-ke kuthiwa "i-polymer powder".
ukushiyeka:
1. Ukumelana nesimo sezulu kwesincibilikisi kuyinkinga enkulu.Elangeni, izohwamuka ngesikhathi esifushane.Ngisho noma lingekho elangeni, i-interface yokubopha izobola ngokushesha ngenxa yokwakhiwa komgodla;
2. Ukumelana nokuguga, izincibilikisi azikwazi ukumelana nokushisa, wonke umuntu uyakwazi lokhu;
3. Njengoba indlela yokubopha iwukuhlakaza isikhombimsebenzisi sebhodi lokufakelwa, ngokuphambene nalokho, iphinde ibhubhise isikhombimsebenzisi sokubopha.Uma kunenkinga ngale nkinga esigabeni sakamuva, umthelela uzoba yingozi;
4. Asikho isibonelo sokufakwa kwesicelo emazweni angaphandle.Ngokuhlangenwe nakho kwamakhemikhali ayisisekelo avuthiwe phesheya, akunakwenzeka ukuthi ungatholi le nto.
isifinyezo:
I-polymer powder ehlakazeka kabusha:
1. Umkhiqizo we-polymer powder ohlakazeka kabusha uyimpushana encibilika kabusha encibilika emanzini, eyi-copolymer ye-ethylene ne-vinyl acetate, ene-polyvinyl alcohol njenge-colloid evikelayo.
2. I-VAE redispersible polymer powder inezinto zokwenza ifilimu, isixazululo samanzi esingu-50% sakha i-emulsion, futhi sakha ifilimu efana nepulasitiki ngemva kokubekwa engilazini amahora angu-24.
3. Ifilimu eyakhiwe inokuguquguquka okuthile nokumelana namanzi.Ingafinyelela ezingeni likazwelonke.
4. I-polymer powder e-redispersible inokusebenza okuphezulu: inekhono eliphezulu lokubopha, ukusebenza okuyingqayizivele nokusebenza okuvelele okungangeni manzi, amandla amahle okubopha, inika udaka olunokumelana okuhle kakhulu kwe-alkali, futhi ingathuthukisa ukunamathela namandla okuguquguquka kodaka Ngaphezu kwepulasitiki, ukumelana nokugqoka. kanye nokwakhiwa, inokuguquguquka okunamandla kudaka lokulwa nokuqhekeka.
I-Resin powder:
1. I-resin polymer powder iwuhlobo olusha lwesilungisi somkhiqizo se-polymer, inhlaka, i-polymer yamangqamuzana aphezulu, kanye nempushana ye-polymer egaywe kahle.
2. I-polymer ye-resin powder inokuqina okujwayelekile, ukumelana nokugqoka, ukuhlakazeka okungalungile, abanye bazizwa be-flocculent (kufanele kube yizinto ezinama-porous njenge-sepiolite), futhi kukhona izimpushana ezimhlophe (kodwa zibe nephunga elimnandi elifana ne-parafini).
3. Amanye ama-resin powders ayagqwala ebhodini, futhi ukuvimbela amanzi akulungile.
4. Ukumelana nesimo sezulu kanye nokumelana namanzi kwe-resin polymer powder kuphansi kune-polymer powder.Ukumelana nesimo sezulu kuyinkinga enkulu.Elangeni, izohwamuka ngesikhathi esifushane.Ngisho noma lingekho elangeni, i-interface yokubopha izokwenza Ngenxa yokuthi iwukwakhiwa komgodi, izophinde ibole ngokushesha.
5. I-resin polymer powder ayinakho ukubumba, ingasaphathwa eyokuguquguquka.Ngokwezindinganiso zokuhlola udaka lwangaphandle lokufakwa odongeni, izinga lomonakalo kuphela webhodi le-polystyrene elihlangabezana nendinganiso.Ezinye izinkomba azikho ezingeni.
6. I-resin polymer powder ingasetshenziselwa kuphela ukuhlanganisa amabhodi e-polystyrene, futhi ayikwazi ukusetshenziselwa ukuhlanganisa ubuhlalu obune-vitrified namabhodi angashi.
