MUPOROFITA
Kusarudzwa kwakaringana kwechisimbiso kunofanirwa kufunga nezvechinangwa chejoint, saizi yejoint deformation, saizi yejoint, iyo substrate yejoinhi, nharaunda umo majoini anobatika, uye michina zvinhu izvo sealant inodiwa kuti iwane. Pakati pavo, ukuru hwejoinhi hunotaridzirwa nemhando yejojo uye hukuru hunotarisirwa hwejojo deformation.
Kuti uve nechokwadi chehupenyu hwakakwana hwebasa uye kushanda kwechisimbiso, kusarudzwa kwakarurama kwechisimbiso kunofanira kunyatsotariswa. Kazhinji, matanho matatu anogona kutorwa kuve nechokwadi chekuti sealant inosvika pahupenyu hwayo hwekugadzira.
- 1. Dhizaina seams nesainzi uye zvine musoro zvinoenderana nezvinodiwa zvekushandisa uye nharaunda;
- 2. Sarudza zviratidzo zvekushanda izvo sealant inoda kusangana muhutano hwakagadzirirwa;
- 3. Kubva pane zvakatemwa zviratidzo zvekushanda, zvinokurudzirwa kusarudza kunamatira uye kuitisa kuenderana kwakakodzera uye kuongororwa kwekunamatira kuti uone kuti chigadzirwa chakasarudzwa chinosangana nezvinodiwa.
Zvisimbiso zvekuvaka anoita mabasa matatu anotevera kuburikidza nemaitiro ekubatanidza:
- 1. Kukwanisa kuzadza gaka riri pakati pema substrates maviri kana anopfuura kuita chisimbiso:
- 2. Kugadzira chipingamupinyi kuburikidza nehunhu hwayo hwemuviri uye kunamatira kune substrate
- 3. Chengetedza kusimba kwechisimbiso pasi pehupenyu hwayo hunotarisirwa, mamiriro ekushanda, uye nharaunda.
Zvinhu zvikuru zvinotarisa kushanda kwechisimbiso zvinosanganisira kugona kwayo kufamba, michina yemagetsi, kunamatira, kusimba, uye kutaridzika. Mechanical uye michina zvimiro zvinonyanya kureva zviratidzo zvakaita sekuoma, elastic modulus, tensile simba, kubvarura kuramba, kusimba, uye elastic kupora mwero. Paunenge uchiisa chisimbiso, izvo zvakakosha zvekushandisa zvinofanirwa kutariswa ndeye tack yemahara nguva, debonding nguva, sagging, sherufu hupenyu (yehuviri-chikamu chinonamira), extrudability, yakadzika kurapa kumhanya, kusapupa, mutengo, ruvara, uye mutsara shrinkage panguva yekurapa; Panguva imwecheteyo, zvinodikanwa kufunga nezve kuchembera kweiyo sealant, kusanganisira yayo UV radiation kuramba, yakakwira uye yakaderera tembiricha mechanical zvivakwa, thermal hydrolysis, kupisa kuchembera, uye oxidation kuramba.
Adhesion inzira inosanganisira kugadzirira, kushandisa, kurapa, uye kugadzirisa sealant. Hunhu hwekunamira kuita hwakanangana neiyo yekubatanidza zvinhu, sealant, uye adhesion maitiro. Naizvozvo, pakuita kuvaka, pesvedzero yezvinhu zvitatu inofanira kurangarirwa zvizere. Chete nekugadzirisa zvinhu zvitatu zvine musoro uye nekuzvibatanidza organic zvinogona kunamatira kwakakodzera, uye chero dambudziko mune chero chinongedzo rinogona kutungamirira mukukundikana kwekunamatira.
Silicone sealant inoshandiswa mukuvaka inonyanya kupa chisimbiso chemamiriro ekunze uye chisimbiso chechimiro. Pamusoro peiyo yakanaka interface dhizaini, inoenderana maitiro ekuvaka maitiro anofanirwa kuteverwa panguva yekuvaka.
Pane zvishanu zvakakosha zvinodiwa kune yakakodzera interface yepamusoro kurapwa uye gluing:
- Iyo interface yepamusoro inofanirwa kuve yakachena, yakaoma, isina guruva uye chando;
- Kana primer ichidikanwa, inofanira kuiswa panzvimbo yakachena;
- Shandisa zvinhu zvekudzokera kumashure kana tepi yekunamatira sezvinodiwa;
- Paunenge uchiisa chisimbiso, zvinodikanwa kuti uzadze iyo interface gap ne sealant;
- Kukwenya ndiko kuve nechokwadi chekuti seams akatsetseka, chimiro chakakodzera, uye kusangana kwakazara ne substrate.
Silicone sealant inogona zvakare kutariswa seyakanamatira nekuda kwechimiro chayo chemakemikari. Silicone sealing adhesion ndeyechisikigo kemikari inoita, saka matanho ekushandisa akakosha akakosha. Nekuda kwekushandiswa kweOLIVIA silicone sealant munzvimbo dzakawanda dzakasiyana uye nyika, maitiro ekuvaka haagone kutorwa seakazara uye akazara emhando yekusimbisa chirongwa. Hunhu hutongi hwekuvaka hunofanirwawo kuitwa, uye pa-saiti yekunamira kuyedzwa kunofanirwa kuitwa kuti ive nechokwadi chekunamira kwakanaka kwesimba uye kuona chero mazano ane chekuita nekunamatira.
Mukutonga kwemhando yekuvaka chisimbiso, kunamatira uye kuenderana kwechisimbiso uye chigadziko zvinhu zvinofanirwa kutariswa, kusanganisira tsvimbo yekutsigira, kaviri-mativi tepi strip uye zvimwe zvekubatsira zvinhu. Kuti ukwidziridze kuita kwepamusoro kwesilicone sealant, zvinodikanwa kusarudza akasiyana silicone sealants zvichienderana nenzvimbo dzakasiyana dzekuvaka, zvinodiwa, uye zvigadzirwa, uye tenzi akamisikidzwa maitiro ekuvaka. Unyanzvi hwekuvaka husingaenzaniswi hunowanzo dzikamisa kushanda kwepamusoro kwezvisimbiso, zvakadai sekuchenesa pamusoro pe substrate, chiyero che primer inoshandiswa, chiyero chisina kukodzera, kusaenzana kusanganiswa kwezvikamu zviviri zvezvisimbiso, uye kushandiswa kwezvisizvo zvekuchenesa zvinonyungudutsa kana nzira, izvo zvinogona kukanganisa kusungirirwa kwezvisimbiso uye kunyange kutungamirira mukukundikana kwekunamatira, zvakadai sekusafanira kwebubble attachment uye kusarudzwa kwechisimbiso. Saka kusarudzwa kwechisimbiso uye kurongeka kwemaitiro ekuvaka kwakakosha. Nekuunza aya mabasa, zvinogona kubatsira kusarudza yakakodzera sealant nemazvo.
Isingapindi mvura uye Weatherproof Chisimbiso
Mamwe asiri-silicone sealants anowanzo kuchembera nekufamba kwenguva uye pasi pesimba rezvinhu zvinokuvadza munharaunda, kunyanya pasi pe ultraviolet mwaranzi. Nokudaro, pakusarudza chisimbiso, hupenyu hwebasa hwechisimbiso hunofanira kufungwa. Kuvharidzirwa kwemvura kunoshandiswa kuzadza mapeji pakati pezvinhu kudzivirira mhepo, mvura, guruva, nezvimwe. Nokudaro, chisimbiso chinofanira kunyatsoomerera kune substrate, kuitira kuti ikwanise kukunda kuchinja kwehukuru hwekubatana kunokonzerwa nekufamba kwe substrate panguva yekuwedzera kana kudzvinyirira. OLIVIA silicone sealant ine yakanaka UV kuramba, inogona kuchengetedza ingangogara modulus, uye elasticity yayo haichinji mukati metembiricha ye -40 ℃ kusvika +150 ℃.
Low performance sealants anonyanya kushandiswa kuzadza mapundu pasi peyakanyanya static mamiriro kudzivirira kupinda kweguruva, mvura, uye mhepo. Zvisinei, kunyanya kuderera, kuomesa nekufamba kwenguva, uye kusanamatira zvakanaka kunogona kukanganisa kushanda kwavo. Kuenderana, kunamatira, uye makemikari mhedzisiro inofanirwa kutariswa kana uchiishandisa.
Structural Chisimbiso
Iyo sealant inoshandiswa pakusunga chisimbiso inonyanya kuomerera kumhando mbiri dze substrates. Panguva imwecheteyo, inogona kukurira kushushikana kunowanikwa: kushushikana uye kudzvinyirira kushushikana, shear stress. Naizvozvo, usati waisa chisimbiso, kusimba kwemaitiro emajoini aya kunofanirwa kusimbiswa, kuitira kuti vagone kuratidzwa muhuwandu pakuverenga zvinodiwa zveinjiniya. Simba rekugadzira rinoratidzwa maererano ne modulus uye kusimba simba. Structural sealants inoda kusvika kune imwe nhanho yesimba. Chimwe chiitiko chakakosha chekuisa chisimbiso chechimiro ndechekuti chisungo pakati pechisimbiso uye substrate hachikuvadzi nekufamba kwenguva. OLIVIA silicone structural sealants ine kuvimbika kwekuita, hupenyu hurefu hwebasa, uye inokodzera kuiswa chisimbiso.
Chengetedzo Yekusarudza Silicone Sealant Yekuvaka
Kusarudzwa kwakaringana kwechisimbiso hakungosanganisire kusarudza zvinhu zvine hunhu hwakakodzera hwemuviri uye makemikari, asi zvakare inotarisa mhando uye zvimiro zvechisimbiso substrate, dhizaini yekubatanidza (kusanganisira kutsigirwa kana zvakamisikidzwa zvinhu), zvinotarisirwa kuita, zvinodiwa zvekugadzira, uye hupfumi mutengo-unoshanda, izvo zvese zvinotariswa. Iyo inotevera rondedzero inowanzoshandiswa muindasitiri yekuvaka kusarudza sealants.
