Mumunda wekushongedza kwezvivakwa, dombo rechisikigo rinofarirwa nekuda kwekukosha kwayo kwekunaka uye kusimba. Kukanganisa kweStone kwakasikwa, kusanganisira pores uye makatsemuka, zvisinei inorambidza kushandiswa kwayo kwakafara uye kuchengeteka. Saka, tekinoroji yekubatanidza tekinoroji yave nzira huru yekuwedzera kuchengetedzwa uye kugona kwekushandiswa kwematombo. Kudiwa kwekubatanidzwa kwemaitiro ematombo echisikigo kuchakurukurwa munyaya ino pamwe chete nekushandiswa uye kubatsirwa kwe epoxy resin zvinonamatira mukushongedza kwematombo. Isu tichaongorora zvivakwa, kushandiswa uye kugadziridzwa kwe epoxy resin mudombo rakaoma rakarembera uye tinotarisira kusimudzira kwayo mune ramangwana mukushongedza kwekuvaka. Kuziva zvakadzama zviri mukati izvi kuchatibatsira kushandisa zvirinani epoxy resin adhesives kupa iyo chikamu chekuvaka neakawanda kunaka, akachengeteka, ane hushamwari ecologically yekushongedza matombo mhinduro.
Iko kudikanwa kwekubatanidzwa kwemaitiro ematombo echisikigo
Iyo aesthetic mhedzisiro yematombo echisikigo inorumbidzwa zvakanyanya, nekuda kwekureruka kwayo uye yakasikwa manyorerwo uye ruvara, inopa yekuvaka yekushongedza inoyevedza uye yakasarudzika hunhu. Matombo echisikigo simba rakaderera rinobva pazvikanganiso zvaro zvenguva dzose, kunyange zvakadaro, kusanganisira pores, kuputika, makomba, nezvimwewo. Kubatana kwemaitiro kwave kwakakosha zvikuru kuvimbisa kushandiswa kwakazara kwebwe. Structural bonding tekinoroji haingogadziri kukanganisa kwematombo chete, asi zvakare inogadzirisa matambudziko akadai sekusakwana adhesion inogona kukonzerwa nekushandiswa kwesamende dhaka, kuitira kuti ibwe iro rikwanise kusungirirwa kune substrates sesimbi mapuranga. Zvakare zvinobatsira mukushandiswa kwekushongedza kwemadziro ematombo ndiko kusungirirwa kwechimiro, kunyanya mukuvaka kwe facade uye madziro emaketeni. Inosimudzira kutendeseka uye kutaridzika kwechivako uye saka inobatsira tekinoroji yekuvaka kufambira mberi.
Kushandiswa kwe epoxy resin adhesive mukuumbwa kwebwe
Epoxy resin adhesive inoshandiswa zvakanyanya mukushongedza kwematombo uye kugadzirisa nekuda kwekuita kwayo kwakanaka kwekubatanidza. Epoxy resin's molecular chimiro inoratidzira mapoka akawanda, anosanganisira epoxy uye hydroxyl mapoka, ayo anoipa zvinoshamisa kunamatira uye kugona kugadzirisa zvinhu. Epoxy resin's colloid shrinkage rate yakaderera mushure mekurapa mumiririri yawedzerwa, saka inogona kuchengetedza kusimba, kuramba mamiriro ekunze, uye kugadzikana. Uyezve, epoxy resin haigadzirise-zvigadzirwa panguva yekurapa, saka kudzivirira kusvibiswa kwebwe kwechipiri. Nokudaro, zvakakodzera kuvaka munzvimbo dzakawanda, kusanganisira kunze, mukati, uye mamwe mashandisirwo akasiyana.
Zvakanakira epoxy resin adhesive
1.Excellent bonding simba: epoxy mapoka, hydroxyl mapoka uye mamwe mapoka anogona kuumba yakasimba intermolecular mauto nezvinhu zvakadai sedombo nesimbi;
2.Small shrinkage: Iyo shrinkage yecolloid panguva yekurapa inongova 2% ~ 3%, uye iyo yekuzadza inogona kuderedzwa zvakare;
3.Dimensional kugadzikana: Chimiro chakagadzikana mushure mekubatana, chitarisiko chakanaka, uye hazvisi nyore kukanganisa;
4.Weather kuramba: Inogona kukurira masimba omusikirwo akadai semhepo, kudengenyeka kwenyika, uye kuchinja kwetembiricha;
5.Kuchinja kwakasimba: Inokodzera kuvakwa munzvimbo dzakasiyana-siyana pasina mamiriro ekushisa akaoma;
6.Pasina kusvibiswa: Hapana zvinonyungudutsa zvinokuvadza zvinoputika panguva yekurapa kana kusvibiswa kupi zvako kunogadzirwa padombo;
7.Inoshandiswa zvakanyanya: Zvigadzirwa mumhando dzakasiyana-siyana zvinogona kugadzirwa zvichibva pane zvinodiwa nematombo.
Kuipa kwe epoxy resin adhesive
1. High brittleness: Unmodified epoxy resin inopepetwa nyore nyore mushure mekuoma;
2.Nguva pfupi yekuvaka: Epoxy resin adhesives inoda kupedzwa mukati meimwe nguva yenguva, iyo isingakodzeri kune yakaoma mapurojekiti;
3.Safety zvinonetsa: Zvimwe zvigadzirwa zve epoxy resin zvinogona kuunza kuparara; saka, munhu anofanirwa kupa tarisiro chaiyo kune kuchengetedzwa kwekuchengetedza.
Basa re epoxy resin adhesive mudombo rakaoma rakarembera
Kubva pa epoxy resin adhesive yakatanga kugadzirirwa zvakabudirira muGerman Chemical Industry Company muna 1934, zvishoma nezvishoma yakashandiswa zvakanyanya mundima yekuvaka. Pakutanga yakatarisana nekunyorova simende kuvaka dhaka, nzira yekunyorova inokonzeresa "kuchinja kwepathological" mudombo, nokudaro yakashanduka ikava nzira yakaoma yekurembera. Yakanyanya kusimba uye yakasimba, iyo epoxy resin adhesive inoshandiswa nenzira yakaoma yekurembera inogona kuita kuti dombo rive rakazvimiririra kubva kune simende dhaka, zvakanyanya kuderedza matambudziko ekuchena uye kudonha kunokonzerwa nesamende dhaka. Izvi zvinotevera zvinosiyanisa nzira yakaoma yekurembera:
1.High yekuisa mhando: Iyo yakaoma yakaturika nzira inoshandisa simbi zvikamu kutsigira uye kuumba chimiro chakasimba;
2.Fast kuvaka kumhanya: Iyo yakaoma yekurembera nzira haidi simende dhaka uye inogona kukurumidza kupedzisa chinzvimbo uye kusungirira;
3.Kudzvinyirirwa kwemhepo uye kuramba kwekudengenyeka kwenyika: Muzvivakwa zvepamusoro-soro, iyo yakaoma yekurembera nzira yekumisikidza haizodonha nekuda kwekuvaka vibration kana mhepo yekumanikidza;
4.Easy kugadzirisa: Iyo yakaoma yekurembera nzira ndeye modular, iyo iri nyore kune gare gare kugadzirisa uye kutsiva.
Kuumbwa uye kugadziriswa kwe epoxy resin adhesives
Epoxy resin adhesives inowanzo umbwa ne epoxy resin uye kurapa mumiririri. Diluents, mafirita, toughening agents, nezvimwewo zvinosanganisirwawo kuvandudza mashandiro uye mafomu akagadziridzwa epoxy resin adhesives saka kuwedzera kushanda kwawo. Pakati pezvinowanzo shandiswa ma modifiers pane silane coupling agents, toughening agents, etc. Kuburikidza nemaitiro aya ekugadzirisa, kushanduka kwecolloid uye kusimba kunogona kukwidziridzwa zvakakwana kugutsa zvimwe zvinodiwa pakushongedza kwematombo. Kunyanya mumashandisirwo akaita semadziro ekunze uye madziro emaketeni, iyo yakagadziridzwa epoxy resin adhesive inopa hukuru hwekushongedza matombo uye inogona kupa yakavimbika yenguva refu rutsigiro.
Remangwana kuvandudzwa kwe epoxy resin adhesives mukushongedza kwekuvaka
Epoxy resin adhesives inozobhadhara zvakanyanya kune zvinotevera zvichaitika mune yezvivakwa zvekushongedza indasitiri yekuvaka kunyatsoita, kushongedza kwemhando uye kuchengetedza kwezvakatipoteredza.
1.Kudzivirira kwezvakatipoteredza: cheka kushandiswa kwemakemikari ane ngozi uye kusimudza kushanda kwe epoxy adhesives mukudzivirira nharaunda;
2.Kuchinjika: kuwedzera kunatsiridza kuchinjika uye kuderedza brittleness kuburikidza nemolecular chimiro kugadzirisa uye kugadziridza;
3.Construction nyore: gadzira epoxy resin zvigadzirwa zviri nyore kushanda uye kurerutsa maitiro ekuvaka;
4.Enhanced weather resistance: pindura kune zvakasiyana-siyana zvekuchinja kwemamiriro ekunze uye kuvandudza kusimba kwenguva refu kwemamiriro ekunze epoxy adhesives.
Iko kusungirirwa kwebwe kunoenderana zvakanyanya pane epoxy resin adhesive. Kubata kwayo kwakanakisa kwekubatanidza uye kuchinjika kwakasimudzira kuvandudzwa kwematombo akaoma ekurembera tekinoroji, uku ichivandudza aesthetics uye kugona kwekuvaka kwezvivakwa. Materials sainzi inovhura mikana yakawanda ye epoxy resin adhesive application mukushongedza kwematombo, saka ichipa mamwe ekutanga bonding mhinduro dzechikamu chekuvaka.
