Obstract:Leli phepha lihlola ithonya kanye nomthetho we-cellulose ether kwizakhiwo eziphambili zokunamathela kwe-tile ngokusebenzisa izivivinyo ze-orthogonal. Izici eziphambili zokwenza kahle kwazo zinokubhekelwa okuthile okubalulekile ngokulungisa ezinye izakhiwo zezinamathiseli.
Kulezi zinsuku, ukukhiqizwa, ukucubungula kanye nokusetshenziswa kwe-cellulose ether ezweni lami kusendaweni ehamba phambili emhlabeni. Ukuthuthukiswa okwengeziwe kanye nokusetshenziswa kwe-cellulose ether kuyisihluthulelo sentuthuko yezinto ezintsha zokwakha ezweni lami. Ngokuthuthuka okuqhubekayo kwezifiso ze-tile kanye nokwenza kahle kanye nokwenza ngcono ukusebenza kwazo, ukukhethwa kwezinhlobo zezicelo zodaka emakethe yezinto ezintsha zokwakha kucetshisiwe. Kodwa-ke, ukuthuthukisa kanjani ukusebenza okuyinhloko kwezikhangiso ze-tile sekuye kwaba ukuthuthukiswa kwemakethe ye-tile adhesive. ukuqondisa okusha.
1. Hlola izinto ezingavuthiwe
Usimende: I-PO 42.5 usimende ojwayelekile wasePortland okhiqizwa uChangchun Yatai wasetshenziswa kulolu vivinyo.
Isihlabathi se-Quartz: Kusetshenziswe iMesh engu-50-100 kulolu vivinyo, kukhiqizwe eDalin, iMongolia yangaphakathi.
I-RedisPleribleTwetex Powder evuselelayo: I-SWF-04 yasetshenziswa kulolu vivinyo, olukhiqizwe nguShanxi Sanwei.
I-Wood Fiber: I-fiber esetshenziswe kulolu vivinyo ikhiqizwa yizinto zokwakha ze-Changchun Huihuibuange.
I-Cellulose Ether: Lokhu kuhlolwa kusebenzisa i-methyl cellulose ether nge-viscosity ka-40,000, ekhiqizwa nguShandong Ruitai.
2. Indlela yokuhlola kanye nokuhlaziywa kwemiphumela
Indlela yokuhlola yamandla e-Tensile Bond Amandla abhekisa ku-JC / T547-2005. Usayizi wecezu lokuhlola ngu-40mm x 40mm x 160mm. Ngemuva kokwenza, makuyeke ime nge-1D bese ususa amafomu. Welashwa ebhokisini lomswakama njalo ezinsukwini ezingama-27, wabopha ikhanda lokudweba ngebhlokhi lokuhlola nge-epoxy resin, bese ulibeka endaweni yokushisa e-epoxy kanye nomswakama we (50 ± 5). 1D, hlola isampula yokuqhekeka ngaphambi kokuhlolwa. Faka ukulungiswa komshini wokuhlola we-elekthronikhi we-elektroniki we-elekthronikhi ukuqinisekisa ukuthi ukuxhumana phakathi kokulungiswa kanye nomshini wokuhlola akwenziwanga, donsa ijubane ngejubane (250 ± 50) N / S, bese urekhoda idatha yokuhlola. Inani likasimende elisetshenziswe kulolu vivinyo lungu-400g, isisindo esiphelele sezinto ezingokwesi-600g, isilinganiselo se-perthogonal), okuqukethwe yi-clueber tow
2.1 imiphumela yokuhlola nokuhlaziywa
Ngokuvamile, anamathela ngamatiyile alahlekelwa amandla okuqinisa ama-tensile ngemuva kokucwiliswa emanzini.
Kusuka emiphumeleni yokuhlolwa etholwe ukuhlolwa kwe-orthogonal, kungatholakala ukuthi ukukhulisa inani lenani le-cellulose ether ne-ruble powder kungathuthukisa amandla asobhothi athambekele ekutholeni amandla amathathu kumandla amathathu e-ceramic tile Ukunamathela ngemuva kokungena emanzini kanye nesibopho esiseduze ngemuva kwemizuzu engama-20 yokomiswa. Ngakho-ke, ukuxoxa ngenani lokuncipha kokuncipha kwamandla amabhondi ngemuva kokubhapathizwa emanzini kungakhombisa kangcono ithonya lezici ezintathu kulo. Inani elihlobene nokwehla kwamandla linqunywa ngamandla okuqala ngesibopho se-Tensile kanye namandla ashubile ngemuva kokucwiliswa emanzini. Isilinganiso somehluko kwamandla e-bond kumandla okuqala ngesibopho se-Tensile sabalwa.
Ukuhlaziywa kwemininingwane yokuhlola kukhombisa ukuthi ngokwandisa okuqukethwe kwe-cellulose ether ne-ruble powder, amandla e-tensile bond ngemuva kokucwiliswa emanzini emanzini angathuthukiswa kancane. Amandla eBonding angu-0.3% angama-16.0% aphakeme kunaleso 0,1%, futhi ukuthuthukiswa kusobala kakhulu lapho kukhuphuka inani lensimbi yerabha; Lapho inani lingu-3%, amandla okubopha akhuphuka ngo-46,5%; Ngokunciphisa isilinganiso sodaka esihlabathini, amandla e-tensaile bond wokucwiliswa emanzini angancishiswa kakhulu. Amandla e-Bond anciphile ngo-61.2%. Kungabonakala ngendlela enembile kusuka kuMdwebo 1 ukuthi lapho inani le-ruble powder likhuphuka lisuka ku-3% liye ku-5%, inani elilinganiselwe lokwehla kwamandla e-bond likhuphuka ngo-23.4%; Inani le-cellulose ether likhuphuka lisuka ku-0,1% liye kwinqubo engu-0.3%, inani elilinganayo lokuncipha kwamandla ebhondi kukhuphuke ngo-7.6%; Ngenkathi inani elilinganayo lokuncipha kwamandla kwebhondi likhuphuke ngo-12,7% lapho isilinganiso sodaka esihlabathini sasingu-1: 2 uma siqhathaniswa nesi-1: 1. Ngemuva kokuqhathanisa esithombeni, ingatholakala kalula ukuthi phakathi kwezici ezintathu, inani le-awder yerabha kanye nesilinganiso sodaka esihlabathini sinethonya elisobala kumandla ebhondi athambile wokucwiliswa kwamanzi.
Ngokusho kwe-JC / T 547-2005, isikhathi sokumisa sokunamathela kwe-tile sikhulu kune- noma silingana nemizuzu engama-20. Ukwandisa okuqukethwe kwe-cellulose ether kungenza amandla ebhondi ashubile angenwe kancane ngemuva kokuthola umoya imizuzu engama-20, futhi okuqukethwe kwe-cellulose ether kungu-0,2%, 0.3%, kuqhathaniswa nokuqukethwe kwe-0.1%. Amandla ahlanganayo akhuphuke ngo-48.1% no-59.6% ngokulandelana; ukukhulisa inani le-pulephu yerabha futhi kungenza amandla ebhondi ashubile akhuphuke kancane ngemuva kokuthola umoya we-20rain, inani le-cubber powder liqhathaniswa ne-3.0% liqhathaniswa ngo-41.4% ngokulandelana; Ukunciphisa isilinganiso sodaka esihlabathini, amandla e-Tensile Bond ngemuva kwemizuzu engama-20 yomoya ancipha kancane kancane, futhi isilinganiso sodaka esihlabathini sasingu-1: 1, amandla e-Tensile Bond ancishiswa ngo-47,4%. Uma kucatshangelwa inani elilinganayo lokwehliswa kwamandla ebhondi laso kungakhombisa ngokucacile ithonya lezinto ezahlukahlukene, ngezinto ezintathu zomiswa, umthelela wesilinganiso sokuncipha kwamandla ashukumisayo, kepha umthelela wesilinganiso sokudama kuma-Tensile Bond amandla abonakali njengakuqala, kodwa umphumela we-cellulose ether okuqukethwe kusobala njengamanje ngalesi sikhathi. Ngokukhuphuka kokuqukethwe kwe-cellulose ether, inani elilinganayo lokwehla kwamandla alo liyancipha kancane kancane futhi ijika livame ukuba mnene. Kungabonakala ukuthi i-cellulose ether inomphumela omuhle ekuthuthukiseni amandla okuqinisa izibopho zethayi ngemuva kwemizuzu engama-20 yokomiswa.
2.2 Ukuzimisela formula
Ngokuhlola okuhlolwe okungenhla, isifinyezo semiphumela yokwakheka kwe-orthogonal kokuhlola kwatholakala.
Iqembu lenhlanganisela A3 B1 C2 ngokusebenza okuhle lingakhethwa kusuka kusifinyezo semiphumela yokwakhiwa kwesilingo se-orthogonal kanye ne-3.3% kanye ne-3%, futhi isilinganiso sodaka esihlabathini singu-1: 1.5.
3. Isiphetho
