Kwiminyaka yakutshanje, umgubo werabha we-resin omninzi, umgubo werabha onamandla aphezulu onganyangekiyo ngamanzi kunye neminye ipowder yerabha engabizi kakhulu iye yavela kwimarike ukuze ithathe indawo ye-VAE emulsion yendabuko (i-vinyl acetate-ethylene copolymer), eyomiswa ngokutshizwa kwaye iphinda isetyenziswe. Umgubo we-latex osasazekayo, ngoko yintoni umahluko phakathi komgubo werabha we-resin kunye nomgubo we-latex osasazekayo, ngaba umgubo werabha we-resin unokuthatha indawo yomgubo we-latex osasazekayo? IZiko leTekhnoloji yeYongqiang Mortar liya kukukhokela ukuba uhlalutye ngokufutshane umahluko phakathi kwezi zimbini ukuze ufumane isalathiso sakho:
1. Umgubo welatex ophinda uchitheke
Okwangoku, iipowder zepolymer ezisasazekayo ezisetyenziswa kakhulu kwihlabathi liphela zezi: i-vinyl acetate kunye ne-ethylene copolymer rubber powder (VAC/E), i-ethylene kunye ne-vinyl chloride kunye ne-vinyl laurate terpolymer rubber powder (E/VC/VL), i-acetic acid I-vinyl ester kunye ne-ethylene kunye ne-higher fatty acid vinyl ester terpolymer rubber powder (VAC/E/VeoVa), ezi powders zintathu ze-polymer ezisasazekayo zilawula imarike yonke, ngakumbi i-vinyl acetate kunye ne-ethylene copolymer rubber powder I-VAC/E/VeoVa E, inesikhundla esiphambili kwihlabathi liphela kwaye imele iimpawu zobugcisa zeepowders zepolymer ezisasazekayo. Isesona sisombululo sibalaseleyo sobugcisa ngokweemava zobugcisa ngeepolymers ezisetyenziswa ekuguqulweni kwe-mortar:
1. Yenye yeepolima ezisetyenziswa kakhulu emhlabeni;
2. Yiba namava amaninzi okusebenzisa kwicandelo lokwakha;
3. Ingahlangabezana neempawu ze-rheological ezifunekayo kwi-mortar (oko kukuthi, ukusebenza okufunekayo);
4. I-resin ye-polymer kunye nezinye ii-monomers ineempawu ze-low organic volatile compounds (VOC) kunye neegesi ezicaphukisayo eziphantsi;
5. Ineempawu zokuxhathisa i-UV egqwesileyo, ukumelana nobushushu okuhle kunye nokuzinza kwexesha elide;
6. Inokumelana okuphezulu kwe-saponification;
7. Inoluhlu olubanzi kakhulu lobushushu bokutshintsha kweglasi (Tg);
8. Ine-bonding epheleleyo, ukuguquguquka kunye neempawu zoomatshini ezilungileyo;
9. Unamava amade kakhulu kwimveliso yeekhemikhali malunga nendlela yokuvelisa iimveliso ezisemgangathweni ozinzileyo kunye namava ekugcineni uzinzo kwindawo yokugcina izinto;
10. Kulula ukuyidibanisa ne-colloid ekhuselayo (i-polyvinyl alcohol) esebenza kakuhle.
2. Umgubo weresin
Uninzi lweempuphu zerabha ze-“resin” ezithengiswayo ziqulethe into yekhemikhali i-DBP. Ungajonga ubungozi bale nto yekhemikhali, echaphazela ukusebenza ngokwesondo kwamadoda. Inani elikhulu leempuphu zerabha ezinjalo ziqokelelwe kwiindawo zokugcina impahla nakwiilebhu, kwaye ziyaguquguquka ukuya kwinqanaba elithile. Imakethi yaseBeijing, edume ngokuvelisa "umpu werabha", ngoku ivele uhlobo "lwempuphu zerabha" efakwe kwizinyibilikisi ezinamagama ahlukeneyo: umpu we-adhesive onamandla aphezulu, umpu we-adhesive resin, njl. Iimpawu eziqhelekileyo:
1. Ukungasasazeki kakuhle, ezinye zivakala zimanzi, ezinye zivakala ngathi ziyashukuma (kufuneka zibe yinto enemingxuma efana ne-sepiolite), kwaye ezinye zimhlophe kwaye zomile kancinci kodwa zisanuka;
2. Ivumba elibi kakhulu;
3. Kuye kongezwa eminye imibala, kwaye imibala ekhoyo ngoku imhlophe, tyheli, ngwevu, mnyama, bomvu, njl.njl.;
4. Ubungakanani bokongeza buncinci kakhulu, kwaye ubungakanani bokongeza kwitoni enye yi-5~12 kg;
5. Amandla okuqala ayamangalisa. Isamente ayinawo amandla kangangeentsuku ezintathu, kwaye ingayitshisa ibhodi yokukhusela ize iyincamathisele.
6. Kuthiwa ibhodi ye-XPS ingasetyenziswa ngaphandle kwearhente ye-interface.
Ngeesampuli ezifunyenweyo ukuza kuthi ga ngoku, kunokugqitywa kwelokuba yi-resin esekwe kwisinyibilikisi efunxwa zizinto ezikhaphukhaphu ezinemingxuma, kodwa umthengisi ufuna ukuliphepha ngabom igama elithi “isinyibilikisi”, ngoko ke libizwa ngokuba “ngumgubo werabha”
isiphene:
1. Ukumelana kwemozulu kwesinyibilikisi yingxaki enkulu. Elangeni, siya kuguquka ngexesha elifutshane. Nokuba asikho elangeni, ujongano lwe-bonding luya kubola ngokukhawuleza ngenxa yokwakhiwa kwe-cavity;
2. Ukumelana nokwaluphala, isinyibilikisi asimelani nobushushu, wonke umntu uyazi oku;
3. Ekubeni indlela yokubopha ikukuyinyibilikisa indawo edibanisa ibhodi yokwambathisa, ngokuchaseneyo, ikwatshabalalisa indawo edibanisa ibhodi. Ukuba kukho ingxaki kwinqanaba elilandelayo, impembelelo iya kuba yingozi;
4. Akukho mzekelo wokusetyenziswa kwamanye amazwe. Ngenxa yamava avuthiweyo kushishino lweekhemikhali olusisiseko kwamanye amazwe, akunakwenzeka ukuba ungafumani le nto.
isishwankathelo:
Umgubo wepolymer osasazekayo:
1. Imveliso yomgubo welatex ophinda unyibilike yipowder ephinda inyibilike emanzini, eyi-copolymer ye-ethylene kunye ne-vinyl acetate, kwaye isebenzisa i-polyvinyl alcohol njenge-colloid ekhuselayo.
2. Umgubo we-latex ophinda unyibilike we-VAE uneempawu zokwenza ifilimu, isisombululo samanzi esingama-50% senza i-emulsion, kwaye senza ifilimu efana neplastiki emva kokubekwa kwiglasi iiyure ezingama-24.
3. Ifilimu eyenziweyo inokuguquguquka okuthile kunye nokumelana namanzi. Ingafikelela kwimigangatho yesizwe.
4. Umgubo welatex ophinda uchitheke unamandla aphezulu: unamandla aphezulu okubopha, ukusebenza kwawo okungaqhelekanga kunye nokusebenza okugqwesileyo kokungena kwamanzi, amandla amahle okubopha, unika umxube wokumelana okuhle kwe-alkali kwi-mortar, kwaye unokuphucula ukunamathela kunye namandla okuguquguquka kwe-mortar. , i-plasticity, ukumelana nokuguguleka kunye nolwakhiwo, unamandla amakhulu okuguquguquka kwi-mortar echasene nokuqhekeka.
Umgubo weresin:
1. Umgubo werabha we-resin luhlobo olutsha lohlengahlengiso lwerabha, i-resin, i-polymer ye-macromolecular, umgubo werabha ocoliweyo kunye nezinye izinto.
2. Umgubo ngerabha we-resin uqinile ngokubanzi, uxhathisa ukurhawuzelelwa, awusasazeki kakuhle, ezinye zivakala ngathi ziyashukuma (kufuneka zibe zizinto ezinemingxuma efana ne-sepiolite), kunye nomgubo omhlophe (kodwa unevumba elimnandi elifana nele-parafini)).
3. Ezinye iipowder ze-resin ziyayitshisa ibhodi, kwaye ukuthintela amanzi akulunganga.
4. Ukumelana nemozulu kunye nokumelana namanzi komgubo werabha yeresin kuphantsi kunoko komgubo welatex. Ukumelana nemozulu yingxaki enkulu. Elangeni, kuya kuguquka ngexesha elifutshane. Nokuba ayikho elangeni, ujongano lokubopha, Ekubeni lulwakhiwo lwe-cavity, luya konakala ngokukhawuleza.
5. Umgubo werabha we-resin awunakuguquguquka, kwaye awunakuguquguquka. Ngokwemigangatho yokuhlolwa kwe-insulation mortar yangaphandle yeendonga zangaphandle, kuphela izinga lokutshatyalaliswa kwebhodi ye-polystyrene elihlangabezana nomgangatho. Ezinye izalathisi azikho kumgangatho ofanelekileyo.
6. Umgubo weresin ungasetyenziselwa kuphela iibhodi zepolystyrene ezibophayo, kungekhona ukubopha iintsimbi eziqinileyo kunye neebhodi ezingatshiyo.
