Abstract:Leli phepha lihlola umthelela kanye nomthetho we-cellulose ether ezicini eziyinhloko zokunamathelisa amathayili ngokuhlolwa kwe-orthogonal. Izici eziyinhloko zokuthuthukiswa kwayo zinokubaluleka okuthile kwereferensi yokulungisa ezinye izici zokunamathisela amathayela.
Kulezi zinsuku, ukukhiqizwa, ukucubungula kanye nokusetshenziswa kwe-cellulose ether ezweni lami kusendaweni ehamba phambili emhlabeni. Ukuthuthukiswa okuqhubekayo kanye nokusetshenziswa kwe-cellulose ether kuyisihluthulelo sokuthuthukiswa kwezinto ezintsha zokwakha ezweni lami. Ngokuthuthuka okuqhubekayo kwezinamatheliso zamathayela kanye nokwenza kahle okuqhubekayo kanye nokwenza ngcono ukusebenza kwazo, ukukhethwa kwezinhlobo zokufaka udaka emakethe yezinto zokwakha ezintsha kuthuthukisiwe. Kodwa-ke, ukuthi ungaqhubeka kanjani nokwandisa ukusebenza okuyinhloko kokunamathela kwe-tile sekuphenduke ukuthuthukiswa kwemakethe yokunamathisela amathayili. indlela entsha.
1. Hlola izinto zokusetshenziswa
Usimende: Usimende we-PO 42.5 ojwayelekile wasePortland okhiqizwe u-Changchun Yatai usetshenziswe kulokhu kuhlolwa.
Isihlabathi se-quartz: I-50-100 mesh isetshenziswe kulokhu kuhlolwa, ekhiqizwa e-Dalin, e-Inner Mongolia.
Impushana ye-latex ehlakazeka kabusha: I-SWF-04 isetshenziswe kulokhu kuhlolwa, ekhiqizwe ngu-Shanxi Sanwei.
I-Wood fiber: I-fiber esetshenziswe kulokhu kuhlolwa ikhiqizwa yi-Changchun Huihuang Building Materials.
I-Cellulose ether: Lokhu kuhlolwa kusebenzisa i-methyl cellulose ether ene-viscosity engu-40,000, ekhiqizwe ngu-Shandong Ruitai.
2. Indlela yokuhlola nokuhlaziywa kwemiphumela
Indlela yokuhlola yamandla ebhondi eqinile ibhekisela ku-JC/T547-2005 evamile. Usayizi wesiqephu sokuhlola 40mm x 40mm x 160mm. Ngemuva kokwenza, ake ime i-1d bese ususa i-formwork. Ilashwe ebhokisini elinomswakamo elihlala njalo izinsuku ezingama-27, ibophe ikhanda lomdwebo nebhulokhi yokuhlola nge-epoxy resin, bese ifakwa ebhokisini lokushisa elingashintshi kanye nomswakamo ezingeni lokushisa elingu-(23±2)°C kanye nomswakama ohlobene ( 50±5)%. 1d, Hlola isampula ukuze uthole imifantu ngaphambi kokuhlolwa. Faka okokusebenza emshinini wokuhlola we-electronic universal tensile ukuze uqinisekise ukuthi ukuxhumeka phakathi kwesakhiwo nomshini wokuhlola akugobile, donsa isifanekiso ngesivinini esingu-(250±50) N/s, bese urekhoda idatha yokuhlola. Inani likasimende elisetshenziswe kulokhu kuhlolwa ngu-400g, isisindo sezinye izinto singama-600g, isilinganiso se-water-binder sinqunyelwe ku-0.42, futhi umklamo we-orthogonal (izici ezi-3, amazinga angu-3) uyamukelwa, futhi izici zingukuqukethwe ye-cellulose ether, okuqukethwe kwe-rubber powder kanye nesilinganiso sikasimende nesihlabathi, ngokusho kokuhlangenwe nakho kwangaphambilini kocwaningo ukuze kunqunywe umthamo othize wesici ngasinye.
2.1 Imiphumela yokuhlolwa nokuhlaziya
Ngokuvamile, izinamathiselo zamathayili zilahlekelwa amandla esibopho esiqinile ngemva kokucwiliswa emanzini.
Kusukela emiphumeleni yokuhlolwa etholwe ukuhlolwa kwe-orthogonal, kungatholakala ukuthi ukwandisa inani le-cellulose ether kanye ne-rubber powder kungathuthukisa amandla esibopho esiqinile sokunamathisela kwethayela ngezinga elithile, futhi ukunciphisa isilinganiso sodaka nesihlabathi kunganciphisa amandla ayo. amandla ebhondi eqinile, kodwa umphumela wokuhlola 2 otholwe ukuhlolwa kwe-orthogonal awukwazi ukubonisa ngokunembile umthelela wezinto ezintathu kumandla webhondi eqinile ye-adhesive yethayela le-ceramic ngemva kokucwiliswa emanzini. kanye nesibopho esiqinile ngemuva kwemizuzu engama-20 yokomisa. Ngakho-ke, ukuxoxa ngenani elihlobene lokuncipha kwamandla ebhondi eqinile ngemva kokucwiliswa emanzini kungabonisa kangcono umthelela wezinto ezintathu ezikuwo. Inani elihlobene lokuncipha kwamandla linqunywa amandla ebhondi eqinile yasekuqaleni kanye namandla aqinile ngemva kokucwiliswa emanzini. Isilinganiso somehluko kumandla ebhondi kumandla ebhondi yasekuqaleni sibaliwe.
Ukuhlaziywa kwedatha yokuhlola kubonisa ukuthi ngokwandisa okuqukethwe kwe-cellulose ether ne-rubber powder, amandla ebhondi eqinile ngemva kokucwiliswa emanzini angathuthukiswa kancane. Amandla okubophezela kwe-0.3% yi-16.0% ephakeme kunaleyo ye-0.1%, futhi ukuthuthukiswa kubonakala kakhulu lapho inani le-rubber powder lenyuka; Uma inani liyi-3%, amandla okubopha akhuphuka ngo-46.5%; ngokunciphisa isilinganiso sodaka nesihlabathi, amandla esibopho esiqinile sokucwiliswa emanzini angancishiswa kakhulu. Amandla ebhondi ehle ngo-61.2%. Kungabonakala ngokunembile ku-Figure 1 ukuthi uma inani le-raber powder likhuphuka lisuka ku-3% liye ku-5%, inani elihlobene nokwehla kwamandla ebhondi likhuphuka ngo-23.4%; inani le-cellulose ether likhuphuka lisuka ku-0.1% liya Kunqubo ka-0.3%, inani elihlobene lokuncipha kwamandla ebhondi lenyuke ngo-7.6%; kuyilapho inani elihlobene lokuncipha kwamandla ebhondi likhuphuke ngo-12.7% lapho isilinganiso sodaka nesihlabathi sasingu-1:2 uma siqhathaniswa no-1:1. Ngemva kokuqhathanisa emfanekisweni, kungatholakala kalula ukuthi phakathi kwezici ezintathu, inani lempushana yerabha kanye nesilinganiso sodaka nesihlabathi kunethonya elisobala kakhulu emandleni esibopho esiqinile sokucwiliswa kwamanzi.
Ngokusho kwe-JC/T 547-2005, isikhathi sokumisa se-adhesive tile sikhulu noma silingana nemizuzu engu-20. Ukwandisa okuqukethwe kwe-cellulose ether kungenza amandla ebhondi eqinile akhule kancane kancane ngemva kokuphefumula imizuzu engu-20, futhi okuqukethwe kwe-cellulose ether kungu-0.2%, 0.3%, uma kuqhathaniswa nokuqukethwe okungu-0.1%. Amandla okubumbana anyuke ngo-48.1% kanye nama-59.6% ngokulandelana; ukwandisa inani le-powder yenjoloba nakho kungenza amandla esibopho esiqinile akhule kancane kancane ngemva kokuphefumula kwe-20imvula, inani le-powder yenjoloba ngu-4%, 5% % uma kuqhathaniswa no-3%, amandla esibopho akhuphuke ngo-19.0% no-41.4% ngokulandelana; kunciphisa isilinganiso sodaka nesihlabathi, amandla ebhondi eqinile ngemva kwemizuzu engu-20 yomoya ehla kancane kancane, futhi isilinganiso sodaka nesihlabathi sasingu-1:2 Uma kuqhathaniswa nesilinganiso sodaka esingu-1:1, amandla ebhondi eqinile ancipha ngo-47.4% . Uma kucatshangelwa inani elihlobene lokuncishiswa kwamandla ebhondi yayo kungabonisa ngokucacile ithonya lezici ezihlukahlukene, ngokusebenzisa izici ezintathu, kungatholakala ngokucacile ukuthi inani elihlobene lokuncipha kwamandla ebhondi eqinile ngemva kwemizuzu engama-20 yokoma, ngemva kuka-20. amaminithi okoma , umthelela wesilinganiso sodaka emandleni ebhondi eqinile awusabalulekile njengangaphambili, kodwa umphumela wokuqukethwe kwe-cellulose ether usobala kakhulu ngalesi sikhathi. Ngokukhula kokuqukethwe kwe-cellulose ether, inani elihlobene lamandla ayo liyancipha kancane kancane futhi ijika livame ukuba mnene. Kungabonakala ukuthi i-cellulose ether inomphumela omuhle ekuthuthukiseni amandla okubopha okunamathiselwe kwe-tile ngemva kwemizuzu engu-20 yokomisa.
2.2 Ukunqunywa kwefomula
Ngokusebenzisa izivivinyo ezingenhla, isifinyezo semiphumela yomklamo wokuhlola we-orthogonal watholakala.
Iqembu lezinhlanganisela A3 B1 C2 elisebenza kahle kakhulu lingakhethwa esifinyezweni semiphumela yokuklama yokuhlolwa kwe-orthogonal, okungukuthi, okuqukethwe kwe-cellulose ether ne-rubber powder ngu-0.3% no-3%, ngokulandelana, kanye nesilinganiso sodaka. ukuya esihlabathini ngu-1:1.5.
3. Isiphetho
(1) Ukwandisa inani le-cellulose ether kanye ne-rubber powder kungakhuphula amandla esibopho esiqinile se-adhesive enamathelayo ngokwezinga elithile, kuyilapho kunciphisa isilinganiso sodaka nesihlabathi, amandla esibopho esiqinile ayancipha, kanye nesilinganiso sodaka nesihlabathi. umphumela yenani le-cellulose ether kumandla ebhondi eqinile yokunamathela kuthayela we-ceramic ngemva kokucwiliswa emanzini ubaluleke kakhulu kunomphumela wenani le-cellulose ether kuwo;
(2) Inani le-cellulose ether linethonya elikhulu kakhulu emandleni esibopho esiqinile se-adhesive enamathelayo ngemva kwemizuzu engu-20 yokomiswa, okubonisa ukuthi ngokulungisa inani le-cellulose ether, okunamathelayo kwethayela kungathuthukiswa kahle ngemva kwemizuzu engu-20 yokoma. Ngemuva kokuqina kwesibopho esiqinile;
(3) Uma inani lempuphu yenjoloba lingu-3%, inani le-cellulose ether lingu-0.3%, futhi isilinganiso sodaka nesihlabathi singu-1: 1.5, ukusebenza kwe-adhesive tile kungcono, okuyinto engcono kakhulu kulokhu kuhlolwa. . Inhlanganisela yezinga elihle.
