Chimiro chematombo chinoshamisa, zvichida nzira yebindu kana rusvingo rwakanaka, rwakanyatsogadzirwa kubva kumatombo echisikigo. Zvichida ne epoxy resin, matombo aya akabatanidzwa pamwechete. Kunyange zvazvo epoxy resin ichirumbidzwa nokuda kwekunamatira kwayo kukuru, chii chinoitika kana mvura ikapinda? Kuchengetedza zvivako zvematombo nekufamba kwenguva kunoenderana nekudzivisa mvura munzvimbo dzekunze kana nzvimbo yakakwirira-yakanyorova. Iri bepa rinoongorora chinongedzo chinokatyamadza mukubatana kwematombo pakati pe epoxy resin nekuramba mvura. Ngationgororei pasi pekumanikidzwa, hunyoro, uye bvunzo yenguva kuti chisungo ichi chakamira sei.
Epoxy Resin uye Basa Rayo muDombo Bonding
Epoxy resin inoshandiswa zvakanyanya mukubatanidza matombo nekuda kwesimba rayo rekunamatira zvinhu, izvo zvinogona kumira mitoro inorema uye inopa kusimba kwakasimba. Yakakurumbira mukuvaka, kuvezwa, uye kunyangwe mamwe mashandisirwo emukati, resin inoumba yakasimba kemikari chisungo kazhinji chakasimba kupfuura matombo pachawo. Granite, marble, uye slate ndezvimwe zvezvinhu zvakasvibirira, zvisiri-porous izvo Epoxy yakanakira kusungirirana nekuda kwekusimba kwayo, inokurumidza kurapa nguva, uye pamusoro pekugadzirisa. Asi epoxy yekushanda kwenguva refu inowanzoedzwa kana yakanyura mumvura-kubva pakunaya kwemvura, kunyorova kwepamusoro, kana kusangana kwemvura yakananga.
Mvura inogona kukanganisa zvinonamira zvakawanda, ichinetesa chisungo pakati pezvinhu nekupinda mukati kana kupindirana nemakemikari ari mukunamira. Pano tiri kubvunza kana epoxy resin, munzvimbo dzine hunyoro hwepamusoro, inogona kuchengetedza chisungo chayo chakasimba pakati pematombo kana yakatarisana nemvura uye kuti yakasiyana sei nedzimwe nzira dzekunamatira.
Iyo Sainzi Kuseri kweEpoxy's Water Resistance
Epoxy resin inowanzo dzivirira mvura, asi zvakakosha kusiyanisa pakati pe "kusapinda mvura" uye "kusapinda mvura." Epoxy haitore kana kupaza pakarepo kana yakanyorova sezvo ichingokwanisa kuramba mvura kusvika padanho rakaderera. Asi kuratidzwa kwemvura kwenguva refu kana kuenderera-kunyanya munzvimbo dzine tembiricha inoshanduka-kunogona kukonzera kudzikira zvishoma. Izvi zvinoitika nekuti dzimwe nguva mvura inopinda mukati me micro-cracks mu epoxy, pamwe ichinetesa chisungo nekufamba kwenguva.
Mvura inodzivirira epoxy formulations yakanyatsogadzirwa nekuwedzera zvinhu, senge zvinoomesa maajenti uye zvinowedzera, izvo zvinosimudzira epoxy kusimba pakurwisa hunyoro. Aya magadzirirwo akajairika muchivako chekunze kana nharaunda dzemugungwa uko kuratidzwa kwemvura kune chokwadi. Kunyange zvakadaro, kusapinda mumvura hakurevi kukwana; Kushandiswa kwe epoxy mukubatanidza dombo kunoenderana nekuziva kuti inguva yakareba sei uye pasi pemamiriro api ayo inogona kumira kuratidzwa kwemvura.
Kuedza kudzivirira kwemvura mukubatana kwematombo
Kuti uongorore epoxy resin yekudzivirira kwemvura mukubatana kwematombo, miedzo yakati wandei yakaitwa pamatombo akasungwa sampuli akaoneswa hunyoro nekufamba kwenguva. Zvimwe zvezvisarudzo zvikuru ndezvizvi:
1. Yekutanga Bond Simba
Mukuedza kwekutanga, epoxy yakaratidza kunamatira kwakanakisa kumhando dzakasiyana dzematombo, kusanganisira granite nemarble, ichigadzira chisungo chaive chakasimba zvakakwana kubata pasi pemitoro inorema. Kuratidzwa kwenguva pfupi kumvura kwaisave nemhedzisiro pane iyi yekutanga chisungo simba, zvichireva kuti epoxy zvisungo zvakasimba nedombo kunyangwe munzvimbo dzine hunyoro.
2.Kuwedzerwa Mvura Yakawedzerwa
Mushure mekunyudza matombo akasungwa mumvura kwemaawa makumi maviri nemana, maawa makumi mana nemasere, uye vhiki, shanduko dzakatanga kuoneka mune epoxy bond. Kunyange zvazvo kuratidzirwa kwenguva pfupi kwakanga kusina mugumisiro muduku, pashure pevhiki zvisungo zvakatanga kuratidza zviratidzo zvokuora. Resin yakagadzira kutsemuka kwemicroscopic uye kumwe kushanduka kunoratidza kupindira kwemvura. Dombo rakaramba rakasungwa, asi kutendeseka kwechisungo kwakaderera uye kwakatanga kuratidza kushushikana kwepfungwa.
3.Temperature Fluctuations
Tembiricha inoita basa rakakosha mukuti epoxy inosangana sei nemvura. Matombo epasi pemvura akanyura akasungwa ne epoxy akaiswa pasi pekutsinhanisa kwepamusoro uye kwakaderera tembiricha. Iko kushanduka kwekushisa kwakagadzira kuwedzera uye kuderera mumatombo uye epoxy, saka ichimhanyisa micro-cracking. Aya madiki akatsemuka anoita kuti mvura ipfuure nyore nepakati pechisungo, saka ichidzikisira yakajairika nekufamba kwenguva.
4.UV Exposure uye Humidity
Zvekunze zvekushandisa zvakare zvinosanganisira UV kuratidzwa. Kunyangwe mwenje weUV waive usina mhedzisiro yakananga pakuramba kwemvura, yakatsvukisa epoxy zvishoma, zvichiratidza shanduko yepasi. Kusimba kwechisungo cheepoxy kwakadzikira nekukurumidza munzvimbo dzine hunyoro hwepamusoro sezvo mwando wakaburitsa mikana yakawanda yekuti mvura ipinde mune chero mapores kana makatsemuka.
Kuenzanisa nemamwe maAdhesives
Muzvidzidzo zvekudzivirira mvura, epoxy resin dzimwe nguva inofananidzwa nemamwe matombo anonamira anosanganisira polyurethane uye simende-based adhesives. Kunyangwe simende-based adhesives ine yakanaka yekutanga mvura kuramba, nekufamba kwenguva mvura yakananga inogona kuita kuti varasikirwe nesimba rakawanda. Sezvineiwo, zvinonamira zve polyurethane hazvina simba rakafanana rekutanga senge epoxy asi zvine zvishoma zviri nani kuchinjika pasi petembiricha uye hunyoro shanduko.
Mukushandiswa kwehunyoro hwepamusoro, epoxy yaiwanzopfuura samende-based adhesives asi yakaratidza zvimwe zvisingakwanisi kana zvichienzaniswa nezvinonamira zvinochinjika se polyurethane maererano nekureba kwemvura kuramba. Epoxy ichiri nani, kunyange zvakadaro, muzvirongwa umo kushanduka kusinganyanyi kukosha pane yekutanga chisungo simba uye kusimba.
Epoxy resin inopa yakanakisa kubatanidza simba rekushandisa kwematombo, zvichiita kuti ive sarudzo yakanaka kune akawanda ekumisikidza uye ekushongedza anoshandiswa. Kunyangwe ichiratidzira kumira zvakanaka kwemvura, kugara uye kusimba kwemvura kuratidzwa-kunyanya mukushanduka kwetembiricha-kunogona kukanganisa kusimba kwayo. Mvura inodzivirira epoxy formulations uye mamwe ekuisa chisimbiso maitiro anobatsira kuwedzera hupenyu hwemabhondi anoshandiswa kunze kwekunze kana nzvimbo dzakanyorova. Kunyangwe zvazvo epoxy ingasave isina mvura zvachose, inogona kuva yakanaka uye yakavimbika glue yebwe rekubatanidza nekushandisa kwakaringana uye zvinonetsa kwezvakatipoteredza.
