Kwiminyaka yakutshanje, uninzi lwepolymer yomgubo we-resin, umgubo wepolymer onganyangekiyo wamanzi kunye nolunye umgubo wepolymer onexabiso eliphantsi kakhulu luye lwavela emarikeni ukuze luthathe indawo ye-VAE emulsion yemveli (vinyl acetate-ethylene copolymer), eyomisiweyo kwaye yomiswe. yenziwe ngepolymer powder enokuphinda isetyenziswe.I-polymer powder esasaziweyo, ngoko ke yintoni umahluko phakathi komgubo we-resin kunye ne-polymer powder ephindwe kabini, ingaba i-resin powder ingathatha indawo yepolymer powder?Iziko leTekhnoloji yoMortar liya kukukhokelela ukuba uhlalutye ngokufutshane umahluko phakathi kwezi zimbini kwireferensi yakho:
(1), umgubo wepolymer onokuphinda uhlakazwe
Okwangoku, i-polymer powders enokuphinda isetyenziswe esetyenziswa kakhulu kwihlabathi zezi: i-vinyl acetate kunye ne-ethylene copolymer powder (VAC / E), i-ethylene, i-vinyl chloride kunye ne-vinyl laurate ternary copolymer powder (E / VC / VL), i-acetic acid iVinyl ester, i-ethylene. kunye ne-acid ephezulu enamafutha e-vinyl ester ternary copolymer powder (VAC/E/VeoVa), ezi zintathu zepolymer zomgubo zilawula imarike yonke, ngakumbi ivinyl acetate kunye ne-ethylene copolymer powder VAC/EE, ikwindawo ephambili kwintsimi yehlabathi kwaye imele ubugcisa. iimpawu zepolymer powder enokuphinda ihlakazwe.Isesona sisombululo sihle sobuchwephesha ngokwamava obugcisa kunye neepolymers ezisetyenziswa kuhlengahlengiso lodaka:
1. Yenye yeepolima ezisetyenziswa kakhulu ehlabathini;
2. Amava esicelo kwintsimi yolwakhiwo ngowona mkhulu;
3. Iyakwazi ukuhlangabezana neempawu ze-rheological ezifunwa ngudaka (oko kukuthi, ukwakhiwa okufunekayo);
4. I-resin ye-polymer kunye namanye ama-monomers aneempawu ze-organic volatile matter (VOC) kunye negesi ephantsi enomsindo;
5. Ineempawu zokumelana ne-UV ebalaseleyo, ukumelana nobushushu obuhle kunye nokuzinza kwexesha elide;
6. Ukuchasa okuphezulu kwi-saponification;
7. Inolona luhlu lubanzi lotshintsho lweglasi (Tg);
8. Inobambiso olugqwesileyo olubanzi, ukuguquguquka kunye neempawu zoomatshini;
9. Yiba nelona xesha lide kwimveliso yeekhemikhali zendlela yokuvelisa iimveliso ezisemgangathweni ezizinzile kunye namava ekugcineni uzinzo lokugcina;
10. Kulula kakhulu ukudibanisa ne-colloid yokukhusela (i-polyvinyl alcohol) kunye nokusebenza okuphezulu.
(2), umgubo wentlaka
Uninzi lwe "resin" yepolymer powder kwimarike iqulethe i-chemical substance DBP.Unokujonga ubungozi bale khemikhali, echaphazela umsebenzi wesondo wesilisa.Isixa esikhulu solu hlobo lwepolymer powder lufakwe kwindawo yokugcina impahla kunye nakwibhubhoratri, kwaye inokuguquka okuthile.Kwimakethi yaseBeijing, edume ngobuninzi bayo be "polymer powder", ngoku kukho "umgubo wepolymer" ofakwe kwi-solvents enamagama ahlukeneyo: umgubo wepolymer onganyangekiyo wamanzi, i-resin polymer powder, njl. Iimpawu eziqhelekileyo:
1. I-Dispersibility engalunganga, abanye baziva bemanzi, abanye baziva be-flocculent (kufuneka ibe yimpahla ene-porous efana ne-sepiolite), abanye bamhlophe kwaye bome kancinci kodwa basanuka kakubi;
2. Ivumba elibi kakhulu;
3. Eminye imibala yongezwe, kwaye imibala evelayo ngoku imhlophe, tyheli, greyi, mnyama, bomvu, njl.;
4. Isixa sokongeza sincinci kakhulu, kwaye inani lokongezwa kwetoni enye ngu-5-12 kg;
5. Amandla okuqala alungile ngokumangalisayo.I-samente ayinayo amandla kwiintsuku ezintathu, kwaye ibhodi yokugquma iyakwazi ukugqwala kwaye ibambelele;
6. Kuthiwa ibhodi ye-XPS ayifuni i-agent ye-interface.
Ngokusebenzisa iisampulu ezifunyenweyo ukuza kuthi ga ngoku, kunokugqitywa ukuba yi-resin esekelwe kwi-solvent ekhangiswa ngezinto ezikhanyayo ezikhanyayo, kodwa umthengisi ufuna ukuphepha ngamabomu igama elithi "i-solvent", ngoko kuthiwa "i-polymer powder".
ukusilela:
1. Ukumelana nemozulu ye-solvent yingxaki enkulu.Elangeni, iya kuba ngumphunga ngexesha elifutshane.Nokuba akukho elangeni, i-bonding interface iya kubola ngokukhawuleza ngenxa yokwakhiwa kwecavity;
2. Ukuchasana nokuguga, izinyibilikisi azikwazi ukumelana nobushushu, wonke umntu uyayazi le nto;
3. Ekubeni i-bonding mechanism kukuchitha i-interface yebhodi ye-insulation, ngokuchaseneyo, iphinda itshabalalise i-bonding interface.Ukuba kukho ingxaki kule ngxaki kwinqanaba elilandelayo, impembelelo iya kuba yingozi;
4. Akukho mzekelo wokusetyenziswa kumazwe angaphandle.Ngamava ekhemikhali aqolileyo asisiseko aphesheya, akunakwenzeka ukuba ungafumani le mpahla.
isishwankathelo:
I-polymer powder enokuchithwa kwakhona:
1. Imveliso ye-polymer powder i-dispersible powder yi-powder-soluble redispersible powder, eyi-copolymer ye-ethylene kunye ne-vinyl acetate, kunye ne-polyvinyl alcohol njenge-colloid ekhuselayo.
2. I-VAE i-polymer ehlaziywayo i-polymer powder ineempawu zokwenza ifilimu, i-50% isisombululo samanzi senza i-emulsion, kwaye yenza ifilimu efana neplastiki emva kokufakwa kwiglasi kwiiyure ezingama-24.
3. Ifilimu eyenziweyo inokuguquguquka okuthile kunye nokuchasana kwamanzi.Inokufikelela kumgangatho wesizwe.
4. I-polymer powder e-redispersible inokusebenza okuphezulu: inamandla okudibanisa okuphezulu, ukusebenza okukodwa kunye nokusebenza okugqwesileyo kokungabikho kwamanzi, amandla okudibanisa okulungileyo, i-endows udaka olunokumelana okugqwesileyo kwe-alkali, kwaye inokuphucula ukubambelela kunye namandla aguquguqukayo odaka Ukongeza kwiplastiki, ukuxhathisa ukunxiba. kunye nokwakhiwa, inokuguquguquka okunamandla kwi-anti-cracking mortar.
I-resin powder:
1. I-resin polymer powder luhlobo olutsha lwesilungisi semveliso yepolymer, intlaka, i-polymer ephezulu yemolekyuli, kunye nomgubo wepolymer ocoliweyo.
2. I-polymer ye-resin powder inokuqina okuqhelekileyo, ukumelana nokugqoka, ukusabalalisa kakubi, abanye baziva be-flocculent (kufuneka ibe yimpahla ene-porous efana ne-sepiolite), kwaye kukho i-powders emhlophe (kodwa ibe nephunga elibukhali elifana ne-kerosene).
3. Eminye i-resin powders i-corrosion kwibhodi, kwaye ukukhutshwa kwamanzi akufanelekanga.
4. Ukumelana nemozulu kunye nokuchasana kwamanzi kwe-resin polymer powder kuphantsi kunezo zepolymer powder.Ukumelana nemozulu yingxaki enkulu.Elangeni, iya kuba ngumphunga ngexesha elifutshane.Nokuba akukho elangeni, ujongano oludityanisiweyo luya kuba kuba lulwakhiwo lwecango, luya kubola ngokukhawuleza.
5. I-polymer ye-resin powder ayinakho ukubumba, makungabikho ukuguquguquka.Ngokwemigangatho yokuvavanya udaka lwangaphandle lwe-insulation wall, kuphela umlinganiselo womonakalo webhodi ye-polystyrene udibana nomgangatho.Ezinye izalathisi azikho kumgangatho.
6. I-polymer ye-resin powder ingasetyenziselwa kuphela ukudibanisa iibhodi ze-polystyrene, kwaye ayikwazi ukusetyenziselwa ukudibanisa ama-vitrified beads kunye neebhodi ezingenamlilo.
