Ukufafaza ukusetha okusheshayo kwenjoloba asphalt asphalt asphalt i-coating esuselwa emanzini. Uma i-diaphragm ingagcinwa ngokuphelele ngemuva kokufafaza, amanzi ngeke avele ngokuphelele, futhi ama-bub Bubble aminyene azovela kalula ngesikhathi sokubhaka okuphezulu, okuholela ekunciphiseni ifilimu elingavunyelwe, okuholela ekunciphiseni amafilimu angavunyelwe, kanye nokulwa namanzi, anti-corrision kanye nokumelana nesimo sezulu. . Ngoba izimo zemvelo zokulungisa esakhiweni zokwakha zivame ukungalawuleki, kubalulekile ukuthuthukisa ukumelana okushisa okuphezulu kwendwangu eshibhile esheshayo ethathwa ngokushesha asphargel asphargelsplt aspharlproof aspharlproof aspharlproof aspharlproof aspharchproof asphartproof aspharlproof aspharch aspharchproof aspharch aspharch aspharch aspharch aspharch aspharch asphar asphar asphar asphar asphar asphar asphar a aspharch asphar a aphathwe ngecebo.
Kukhethwe ama-cellule cellulose ether ukuthuthukisa ukumelana nokushisa okuphezulu kwezinto ezifashisayo ezifuywayo ezisheshayo ezifashisayo aspharl aspharl aspharl aspharr aspharlsproofing. Ngasikhathi sinye, imiphumela yohlobo nenani le-cellulose ether kwizakhiwo zemishini, ukufafaza ukusebenza, ukumelana nokushisa nokugcinwa kokufafaza okusheshayo kwe-ascrur asphartproof asphartproof asphar asphards aspharlproof asphar asphar asphar asphaltproof asphar asphar asphar asphar asphar asphar asphar asphar asphar asphar asphar asphar asphar asphar asphar asphar asphar asphar asphar asphar asphard aphaya. Umthelela Wokusebenza.
Ukulungiswa kwesampula
Dissolve hydroxyethyl cellulose emanzini angu-1/2 ahleliwe, avuse kuze kube yilapho ichithwe ngokuphelele, bese wengeza ama-emulsifier kanye ne-sodium hydroxide emanzini asele angu-1/2 ahlanganiswe ngokulinganayo ukuze athole isisombululo samanzi, futhi i-pH areVires alawulwa phakathi kuka-11 no-13.
Hlanganisa i-Edulsald asphalt, neoprene latex, i-hydroxyethyl cellulose acateli, defoamer, njll ngokusho kwesilinganiso esithile ukuze uthole ukwaziswa a.
Lungiselela ukugxila okuthile kwe-CA (NO3) isisombululo esingamanzi nje esingamanzi njengento ye-B.
Sebenzisa imishini yokufafaza ekhethekile yokufafaza ukufafaza izinto ezibonakalayo a nezinto ezibonakalayo b ungene ephepheni lokukhishwa ngasikhathi sinye, ukuze kuthintwe yizinto zokwakha ngokushesha ngesikhathi senqubo yokufakelwa kwe-cross atomization.
Imiphumela nengxoxo
Hydroxyethyl cellulose with a viscosity of 10 000 mPa·s and 50 000 mPa·s was selected, and the method of post-addition was adopted to study the effects of the viscosity and addition amount of hydroxyethyl cellulose on the spraying performance of quick-setting rubber asphalt waterproof coatings, Film-forming properties, heat resistance, mechanical properties and storage properties. Ukuze ugweme ukulimala kubhalansi yesistimu okubangelwa ukufakwa kwesixazululo se-hydroxyethylell solution, okuholela ekunciphiseni, i-emulsifier kanye noMlawuli we-PH.
Ithonya Lokubonakala Kwe-HydroxYethyl Cellulose (I-HEC) ekufafeni nasezindaweni ezakhiwe ngefilimu zokugqoka amanzi angenamanzi
Lapho kukhuphuka khona i-hydroxyethyl cellulose (HEC), kuba mthelela omkhulu ekufafeni nasezindaweni ezakha amafilimu ezimboze amanzi angenamanzi. Lapho inani layo lokungezwa lingu-1 ‰, i-HEC enokubonakala kwe-50 000 MPAS kwenza ukubonakala kohlelo lwama-materproof coating lapho kuncipha kakhulu, kanti i-diaphragm ihle kakhulu, futhi i-diaphragm ihlekisa kakhulu, futhi i-diaphragm ingenamthelela omkhulu ekufafeni, futhi i-diaphragm incipha ngokuyisisekelo okujwayelekile.
Umphumela we-hydroxyethyl celtulose (HEC) ekumelaneni nokushisa kokushiswa kwamanzi
I-aspharber eshintshiwe esheshayo yenjoloba irabha i-asphalt asphalt asphalt wafafazwa ephepheni le-aluminium ukulungiselela ukumelana nokuvikelwa kokuqina kokushisa, futhi kwelashwa ngokwemibandela ye-asphalt esuselwa emanzini acacisiwe ku-National Standard GB / T 16777-2008. I-hydroxyethyl cellulose enokubonakala kwe-50 000 MPA SE isisindo esikhulu samangqamuzana. Ngaphezu kokubambezela ukuhwamuka kwamanzi, futhi inomphumela othile oqinisayo, okwenza kube nzima ngamanzi ukuhwamuka kusuka ngaphakathi kokuhlangana, ngakho-ke kuzokhiqiza ama-bulger amakhulu. Isisindo samangqamuzana se-hydroxyethyl celtulose esinokubonaka kwe-10 000 ama-MPA S lincane, elinomthelela omncane emandleni ezinto ezibonakalayo futhi alithinti ukuguquguquka kwamanzi, ngakho-ke akukho zukulwane bubble.
Umphumela wenani le-hydroxyethyl cellulose (i-HEC) engezwe
IHydroxYethyl Cellulose (I-HEC) ene-vivcosity ye-10 000 MPA ikhethwe njengento yocwaningo, kanye nemiphumela yokungezwa okuhlukile kwe-HEC ekusebenzeni kokufafaza kwaphenywa. Uma ucabanga ngokufafaza ukusebenza, ukumelana nokushisa kanye nezindawo zemishini yezimbobo ezingangenzi manzi, kubhekwa ukuthi inani elifanele lokungezwa kwe-hydroxyethyl cellulose lingu-1 ‰.
I-Neoprene Latex e-Stray-Setch-Setched asphalt asphalt asphalt asphalt materproof coatity kanye nomehluko omkhulu ebusweni nasebunzimeni, okuholela ekuhlelekeni kwezinto ezibonakalayo ngesikhathi esifushane ngesikhathi sokugcina. Ngakho-ke, ngesikhathi sokwakhiwa kwesayithi kudinga ukushukunyiswa ngokulinganayo ngaphambi kokuthi kufafazwa, ngaphandle kwalokho kuzoholela kalula ezingozini ezisezingeni eliphakeme. I-Hydroxyyethyl celtulose ingaxazulula ngempumelelo inkinga yokudilisela ye-Spray-Setch-Setch-Setch-asphalt as aspharlproof asphartproof asphartproof asphart aspharlproof asphart aspharlproof aspharch. Ngemuva kwenyanga eyodwa yokugcina, akukho okuhlinzayo. I-viscosity yohlelo ayiguquki okuningi, futhi ukuqina kuhle.
gxila ekuqondeni
1) After hydroxyethyl cellulose is added to the sprayed quick-setting rubber asphalt waterproof coating, the heat resistance of the waterproof coating is greatly improved, and the problem of dense bubbles on the surface of the coating is greatly improved.
2) Ngaphansi kwesisekelo sokuthi ungaphazamisi inqubo yokufafaza, ukusebenza kwefilimu kanye nezinto ezisebenza ngezinto ezibonakalayo, i-hydroxyyethyl celtulose yayizimisele ukuba yi-hydroxyethyl cellulose enokuvunywa kwe-10 000 MPA S, futhi inani lokungezwa lalingu-1 ‰.
3) Ukungezwa kwe-hydroxyyethyl celtulose kuthuthukisa ukuqina kwesitoreji kwe-braid eshiziwe esheshayo ehlelwa amanzi as aspharr-materproof aspharl aspharlproof aspharl aspharlproof aspharl aspharlproof aspharch aspharch aspharlproof aspharch aspharch aspharch asphar asphalt aspharlproof asphalt aspharch aspharlproof aspharch, futhi kungabikho ukuhlinza okwenzeka ngemuva kokugcina inyanga eyodwa.
