Abstract:Iri bepa rinoongorora pesvedzero uye mutemo we cellulose ether pane zvakakosha zvematairi adhesives kuburikidza ne orthogonal kuyedza. Iwo makuru maficha ekugadzirisa kwayo ane kumwe kurehwa kwakakosha pakugadzirisa zvimwe zvimiro zvematairi anonamira.
Mazuva ano, kugadzirwa, kugadzirisa uye kushandiswa kwe cellulose ether munyika yangu vari munzvimbo inotungamira pasirese. Kumwe kusimudzira uye kushandiswa kwe cellulose ether ndiyo kiyi yekuvandudzwa kwezvinhu zvitsva zvekuvaka munyika yangu. Nekuenderera mberi kwekuvandudzwa kwematairi ekunamira uye kuenderera mberi nekugonesa uye kuvandudzwa kwekuita kwavo, kusarudzwa kwemhando dzematehwe ekushandisa mumusika mutsva wezvivakwa zvekuvaka kwakafumiswa. Nekudaro, maitiro ekuwedzera optimize kuita kukuru kwematairi anonamira kwave kusimudzira kwemusika wekunamatira mataira. nzira itsva.
1. Edzai zvigadzirwa
Simende: Iyo PO 42.5 yakajairwa Portland simende yakagadzirwa naChangchun Yatai yakashandiswa mukuyedza uku.
Jecha reQuartz: 50-100 mesh yakashandiswa muyedzo iyi, yakagadzirwa muDalin, Inner Mongolia.
Redispersible latex poda: SWF-04 yakashandiswa muyedzo iyi, yakagadzirwa naShanxi Sanwei.
Wood fiber: Iyo fiber inoshandiswa muyedzo iyi inogadzirwa neChangchun Huihuang Building Materials.
Cellulose ether: Muedzo uyu unoshandisa methyl cellulose ether ine viscosity ye40,000, yakagadzirwa naShandong Ruitai.
2. Nzira yekuedza uye kuongororwa kwemigumisiro
Iyo yekuyedza nzira ye tensile bond simba inoreva chiyero JC/T547-2005. Saizi yebvunzo chidimbu ndeye 40mm x 40mm x 160mm. Mushure mekugadzira, regai imirire 1d uye bvisa fomu. Yakaporeswa mubhokisi rinogara richinyorova kwemazuva makumi maviri nemanomwe, yakasungirira musoro wekudhirowa nechivharo chebvunzo ne epoxy resin, yobva yaiisa mubhokisi rinogara riri tembiricha uye hunyoro patembiricha ye (23±2)°C uye hunyoro hwe (23±2)°C. 50±5)%. 1d, Tarisa sampuli kune yakatsemuka isati yaedzwa. Isa chigadziriso kumuchina wepasirese wemagetsi tensile yekuyedza kuti uve nechokwadi chekuti hukama pakati pechigadziriso nemuchina wekuyedza hauna kukotama, dhonza mufananidzo nekumhanya kwe (250 ± 50) N/s, uye rekodha data rekuyedza. Huwandu hwesimende inoshandiswa muyedzo iyi i400g, huremu hwezvimwe zvinhu 600g, mvura-binder ratio inotarwa pa0.42, uye orthogonal dhizaini (3 zvinhu, 3 mazinga) inotorwa, uye zvinhu ndizvo zviri mukati. ye cellulose ether, zviri mukati mehupfu yerabha uye chiyero chesimende kune jecha, maererano neyakapfuura tsvakurudzo ruzivo kuti uone chiyero chaicho chechinhu chimwe nechimwe.
2.1 Miedzo mhinduro uye ongororo
Kazhinji, madhiri ekunamatira anorasikirwa nekusimba kwechisungo mushure mekunyudzwa mumvura.
Kubva pamhedzisiro yebvunzo yakawanikwa neiyo orthogonal bvunzo, zvinogona kuwanikwa kuti kuwedzera huwandu hweselulosi ether nehupfu yerabha inogona kuvandudza iyo tensile bond simba reanonamira mataira kune imwe nhanho, uye kuderedza chiyero chedhaka kune jecha kunogona kuderedza kusimba kwechisungo chekusimba, asi mhedzisiro yebvunzo 2 yakawanikwa neiyo orthogonal bvunzo haigone kuratidza zvine mutsindo mabatiro ezvitatu zvinhu pakusimba kwechisungo cheiyo ceramic tile adhesive mushure mekunyura mumvura. uye iyo tensile bond mushure memaminitsi makumi maviri ekuomesa. Naizvozvo, kukurukura nezvehukoshi hwekudzikira kwesimba rezvisungo mushure mekunyudzwa mumvura kunogona kuratidza zvirinani kurudziro yezvitatu zviri pairi. Hukoshi hwehumwe hwekudzikira kwesimba hunotarwa neiyo yekutanga tensile bond simba uye kusimba kwesimba mushure mekunyudzwa mumvura. Reshiyo yemusiyano musimba rebhondi kune yekutanga tensile bond simba yakaverengerwa.
Kuongororwa kwe data yekuedza kunoratidza kuti nekuwedzera zvinyorwa zve cellulose ether uye rubber powder, simba rehutano rehutano mushure mekunyudzwa mumvura rinogona kuvandudzwa zvishoma. Simba rekubatanidza re 0.3% ndiro 16.0% yakakwirira kudarika ye0.1%, uye kuvandudzwa kunonyanya kuoneka kana huwandu hwehupfu hwerabha huchiwedzerwa; Kana iyo mari iri 3%, simba rekubatanidza rinowedzera ne 46.5%; nekudzikisira reshiyo yedhaka nejecha, kusimba kwechisungo chekunyudzwa mumvura kunogona kudzikiswa zvakanyanya. Bond simba rakadzikira ne61.2%. Inogona kuonekwa intuitively kubva kuMufananidzo 1 kuti kana huwandu hwehupfu hwerabha huchiwedzera kubva ku3% kusvika ku5%, kukosha kwehuwandu hwekuderera kwesimba rezvisungo kunowedzera ne23.4%; chiyero che cellulose ether chinowedzera kubva ku0,1% kusvika Muchigadziro che 0.3%, kukosha kwehutano hwekusungo kuderera kwakawedzera ne7,6%; nepo kukosha kwesimba rebhondi kuderera kwakawedzera ne12.7% apo reshiyo yedhaka nejecha yaive 1:2 zvichienzaniswa ne1:1. Mushure mekuenzanisa mumufananidzo, zvinogona kuwanikwa nyore nyore kuti pakati pezvinhu zvitatu, kuwanda kwehupfu yerabha uye chiyero chedhaka kune jecha zvine simba rinonyanya kuoneka pane kusimba kwechisungo chekunyudzwa kwemvura.
Maererano neJC/T 547-2005, nguva yekuomesa yekunamatira tile yakakura kudarika kana yakaenzana ne20 min. Kuwedzera zvinyorwa zve cellulose ether zvinogona kuita kuti simba rekusungirirwa riwedzere zvishoma nezvishoma mushure mekufambisa kwemaminetsi makumi maviri, uye zvinyorwa zve cellulose ether ndeye 0.2%, 0.3%, zvichienzaniswa nezviri 0.1%. Simba rakabatana rakawedzera ne 48.1% uye 59.6% maererano; kuwedzera huwandu hwehupfu hwerabha hunogonawo kuita kuti simba rebhondi riwedzere zvishoma nezvishoma mushure memhepo ye20mvura, huwandu hwehupfu hwerabha huri 4%, 5% % kana ichienzaniswa ne3%, simba rezvisungo rinowedzera ne19.0% uye 41.4% maererano; kuderedza kuenzana kwedhaka nejecha, simba rezvisungo mushure memaminitsi makumi maviri emhepo yakaderera zvishoma nezvishoma, uye chiyero chedhaka kune jecha chaiva 1: 2 kana ichienzaniswa nechiyero chedhaka che1: 1, kusimba kwechisungo kunoderedzwa ne47.4%. . Tichifunga nezve kukosha kwehumwe kuderedzwa kwesimba rechisungo chayo kunogona kuratidza zvakajeka pesvedzero yezvinhu zvakasiyana-siyana, kuburikidza nezvinhu zvitatu, zvinogona kuwanikwa zvakajeka kuti kukosha kwekuderera kwekusimba kwechisungo chesimba mushure memaminitsi makumi maviri ekuoma, mushure me20. maminetsi ekuomeswa , kukanganiswa kwedhaka reshiyo pane tensile bond kusimba hakuchina kukosha sepakutanga, asi mhedzisiro ye cellulose ether zviri pachena zvakanyanya panguva ino. Nekuwedzera kwemukati we cellulose ether, kukosha kwayo kwesimba kunoderera zvishoma nezvishoma uye curve inoita kunge yakapfava. Zvinogona kuonekwa kuti cellulose ether ine simba rakanaka pakuvandudza kusungirirwa kwesimba rekunamatira tile mushure memaminitsi makumi maviri ekuoma.
2.2 Formula kutsunga
Kuburikidza nemiedzo iri pamusoro, pfupiso yemhedzisiro ye orthogonal yekuedza dhizaini yakawanikwa.
Boka remisanganiswa A3 B1 C2 ine hunyanzvi hwekuita inogona kusarudzwa kubva muchidimbu chemhedzisiro yekugadzirwa kweorthogonal kuyedza, ndiko kuti, zviri mukati me cellulose ether uye rubber powder ndeye 0.3% uye 3%, zvichiteerana, uye chiyero chedhaka. kujecha ndi1:1.5.
3. Mhedziso
(1) Kuwedzera huwandu hwe cellulose ether uye rubber poda inogona kuwedzera kusimba kwechisungo chekunamatira tile kune imwe nhanho, uku ichideredza chiyero chedhaka kune jecha, iyo tensile bond simba inoderera, uye chiyero chedhaka kune jecha. mhedzisiro yehuwandu hwe cellulose ether pane tensile bond kusimba kweiyo ceramic tile adhesive mushure mekunyudzwa mumvura inonyanya kukosha kupfuura mhedzisiro yehuwandu hweselulosi ether pairi;
(2) Kuwanda kwe cellulose ether kune simba guru pane simba rekubatana kwechisungo chekunamatira tile mushure memaminitsi makumi maviri ekuomeswa, zvichiratidza kuti nekugadzirisa huwandu hwe cellulose ether, iyo tile yekunamatira inogona kuvandudzwa zvakanaka mushure memaminitsi makumi maviri ekuoma. Mushure me tensile bond simba;
(3) Kana huwandu hwehupfu hwerabha huri 3%, huwandu hwe cellulose ether huri 0.3%, uye chiyero chedhaka kune jecha 1: 1.5, kushanda kwekunamatira tile kuri nani, iyo ndiyo yakanakisisa mumuedzo uyu. . Yakanaka level musanganiswa.
