ZVIMWE ZVINHU
Kusarudza kwakakodzera kwechisimbiso kunofanirwa kufunga nezvechinangwa chechisimbiso, saizi yekukanganisika kwejoini, saizi yechisimbiso, substrate yechisimbiso, nharaunda iyo majoini anosangana, uye hunhu hwemakanika hunodiwa kuti chisimbiso chiwane. Pakati pazvo, saizi yechisimbiso inotsanangurwa nerudzi rwechisimbiso uye saizi inotarisirwa yekukanganisika kwejoini.
Kuti chivharo chishande zvakanaka uye chishande zvakanaka, sarudzo chaiyo yechivharo inofanira kunyatsofungwa nezvayo. Kazhinji, matanho matatu anogona kutorwa kuti chivharo chisvike pakugadzirwa kwacho kwakakodzera.
- 1. Gadzira misono yesainzi uye ine musoro zvichienderana nezvinodiwa zvekushandisa nenzvimbo yakapoteredza;
- 2. Sarudza zviratidzo zvekushanda izvo chivharo chinofanira kusangana nazvo muchimiro chakagadzirwa;
- 3. Zvichienderana nezviratidzo zvekushanda zvakatarwa, zvinokurudzirwa kusarudza namatidza uye kuita bvunzo dzinodiwa dzekuenderana uye kunamira kuti uve nechokwadi chekuti chigadzirwa chakasarudzwa chinosangana nezvinodiwa.
Zvinovhara zvekuvaka zvinoita mabasa matatu anotevera kuburikidza nemaitiro ekubatanidza:
- 1. Kukwanisa kuzadza mukaha uri pakati pezvikamu zviviri kana kupfuura kuti zvigadzire chisimbiso:
- 2. Kugadzira chipingamupinyi kuburikidza nehunyanzvi hwayo hwepanyama uye kunamatira kune substrate
- 3. Chengetedza kusimba kwechisimbiso pasi pehupenyu hwayo, mamiriro ekushanda, uye nharaunda.
Zvinhu zvikuru zvinosarudza mashandiro e sealant zvinosanganisira kugona kwayo kufamba, hunhu hwemakanika, kunamira, kugara kwenguva refu, uye chitarisiko. Hunhu hwemakanika uye hwemakanika hunonyanya kureva zviratidzo zvakaita sekuomarara, elastic modulus, simba rekudhonza, kuramba kubvaruka, kuomarara, uye elastic recovery rate. Pakushandisa sealant, zvinodiwa zvikuru zvekushandisa zvinofanirwa kutariswa ndezvenguva isina tack, nguva yekubvisa bonding, kusakara, nguva yesherufu (yezvinonamatira zviviri), kugona kuburitsa, kukurumidza kupora kwakadzika, kusaita furo, mutengo, ruvara, uye kupwanyika kwemutsara panguva yekupisa; Panguva imwe chete, zvakakosha kufunga nezvehunhu hwekukwegura kwe sealant, kusanganisira kuramba kwayo mwaranzi yeUV, hunhu hwemakanika hwepamusoro nepasi, thermal hydrolysis, thermal age, uye kuramba oxidation.
Kunamatira inzira inosanganisira kugadzirira, kushandisa, kugadzika, uye kugadzirisa chisimbiso. Hunhu hwekushanda kwechinamira hunoenderana zvakananga nezvinhu zvinosunga, chisimbiso, uye maitiro ekunamatira. Saka, pakugadzira, simba rezvinhu zvitatu rinofanira kutariswa zvizere. Kunamatira kwakakodzera chete nekugadzirisa zvinhu zvitatu zvine musoro uye kuzvisanganisa nenzira yepanyama ndiko kunogona kuwanikwa, uye chero dambudziko riri muchinamira chero chipi zvacho rinogona kutungamira kukundikana kwekunamatira.
Chivharo chesilicone chinoshandiswa pakuvaka chinonyanya kupa chivharo chinodzivirira mamiriro ekunze uye chivharo chechimiro. Pamusoro pekugadzirwa kwakanaka kweinterface, zvinodiwa zvekuvaka zvinoenderana nazvo zvinofanirawo kuteverwa panguva yekuvaka.
Pane zvinhu zvishanu zvinodiwa pakugadzirisa nekunamira zvakanaka kwenzvimbo yacho:
- Nzvimbo yekushongedza inofanira kunge yakachena, yakaoma, isina guruva kana chando;
- Kana primer ichidikanwa, inofanira kuiswa panzvimbo yakachena;
- Shandisa zvinhu zvinotevedzana kana tepi inonamira sezvinodiwa;
- Paunenge uchishandisa sealant, zvakakosha kuzadza nzvimbo yekubatanidza ne sealant;
- Kukwenya kunoitwa kuti pave nechokwadi chekuti misono yakatsetseka, chimiro chakakodzera, uye kuti pasi pevhu pave nekubatana kwakazara.
Silicone sealant inogonawo kuonekwa sechinamira nekuda kwechimiro chayo chemakemikari. Silicone sealing adhesion inyaya yemakemikari yechisikigo, saka matanho ekushandisa akakodzera akakosha zvikuru. Nekuda kwekushandiswa kweOLIVIA silicone sealant munzvimbo dzakasiyana siyana, zvirevo zvekuvaka hazvigone kuonekwa sechirongwa chakakwana uye chakakwana chekusimbisa mhando. Kutarisirwa kwemhando yekuvaka kunofanirwawo kuitwa, uye kuyedzwa kwenamira panzvimbo yacho kunofanirwa kuitwa kuti kuve nechokwadi chekuti namira yakasimba uye kusimbisa chero mazano ane chekuita nenamira.
Mukutarisira kunaka kwekuvaka sealant, kunamatira uye kuenderana kwesealant nezvinhu zvepasi kunofanirwa kutariswa, kusanganisira tsvimbo inotsigira, tambo ine mativi maviri nezvimwe zvinhu zvinobatsira. Kuti ushandise mashandiro epamusoro esilicone sealant, zvakakosha kusarudza silicone sealants dzakasiyana zvichienderana nenzvimbo dzakasiyana dzekuvaka, zvinodiwa, nezvinhu, uye matekiniki ekuvaka akajairwa. Maitiro ekuvaka asina kuenzana anowanzo ganhurira mashandiro epamusoro esealants, akadai sekuchenesa pamusoro pe substrate, huwandu hweprimer hunoshandiswa, chiyero chisina kunaka, kusanganiswa kwezvikamu zviviri zve sealants, uye kushandiswa kwezvinyungudutsa kana nzira dzisina kururama dzekuchenesa, izvo zvinogona kukanganisa kunamatira kwesealants uye kutotungamira kukundikana kwekunamatira, senge kusarudzwa kusina kunaka kwekubatanidza kunotungamira kumabhuru uye kuchinja ruvara rwesealant. Saka kusarudzwa kwesealant uye kurongeka kwemaitiro ekuvaka kwakakosha. Nekuisa mabasa aya, zvinogona kubatsira kusarudza sealant yakakodzera nemazvo.
Chisimbiso Chisingapindi Mvura uye Chinodzivirira Mamiriro ekunze
Zvimwe zvinhu zvinovhara masimbi zvisiri zvesilicone zvinowanzokwegura nekufamba kwenguva uye zvichikanganiswa nezvinhu zvinokuvadza munharaunda, kunyanya pasi pemwaranzi ye ultraviolet. Saka, pakusarudza chinovhara masimbi, nguva yebasa rechivhara masimbi inofanira kufungwa nezvayo. Chinovhara masimbi chinoshandiswa kuzadza mipata iri pakati pezvinhu kudzivirira mhepo, mvura, guruva, nezvimwewo kuti zvisapfuure nepakati pemipata. Saka, chinovhara masimbi chinofanira kunamatira zvizere kune substrate, kuitira kuti chigone kukunda shanduko muhukuru hwemajoini hunokonzerwa nekufamba kwesubstrate panguva yekuwedzera kana kudzvanywa. OLIVIA silicone sealant ine simba rakanaka rekudzivirira UV, inogona kuchengetedza modulus yakafanana, uye kusimba kwayo hakuchinji mukati mekushisa kwe -40 ℃ kusvika +150 ℃.
Zvivharo zvisina simba rakawanda zvinonyanya kushandiswa kuzadza mipata pasi pemamiriro ezvinhu akaomarara kudzivirira kupinda kweguruva, mvura, nemhepo. Zvisinei, kuderera kwakanyanya, kuomarara nekufamba kwenguva, uye kusanyatsobatirira zvinogona kukanganisa kushanda kwazvo. Kuenderana, kunamira, uye mhedzisiro yemakemikari zvinofanirwa kufungwa nezvazvo pakushandisa izvi.
Chisimbiso cheMaumbirwo
Chisimbiso chinoshandiswa pakusunga chimiro chinonyanya kunamatira kumhando mbiri dzesubstrates. Panguva imwe chete, chinogona kukunda kushushikana kunosangana nako: kushushikana nekumanikidzwa, kushushikana kwekuchekwa. Nokudaro, usati wasunga, simba remaumbirwo emajoini aya rinofanira kusimbiswa, kuitira kuti agone kuratidzwa muhuwandu pakuverenga zvinodiwa zveinjiniya. Simba remaumbirwo rinoratidzwa maererano ne modulus uye simba rekusunga. Zvisimbiso zvemaumbirwo zvinofanirwa kusvika padanho rakati resimba. Chimwe chinhu chakakosha chekusimbisa chimiro ndechekuti kubatana pakati pechisimbiso nesubstrate hakukuvadzi nekufamba kwenguva. Zvisimbiso zvemaumbirwo zveOLIVIA silicone zvine mashandiro akavimbika, hupenyu hurefu hwebasa, uye zvakakodzera kusungwa kwechimiro.
Matanho Ekuchengetedza Pakusarudza Silicone Sealant Yekuvaka
Kusarudzwa kwakakodzera kwechisimbiso hakungosanganisiri chete kusarudza zvinhu zvine hunhu hwakakodzera hwemuviri uye hwemakemikari, asiwo kunofunga nezverudzi uye hunhu hwechisimbiso, dhizaini yemajoini (kusanganisira rutsigiro kana zvinhu zvakaiswa mukati), mashandiro anotarisirwa, zvinodiwa pakugadzira, uye mari isingadhuri, zvese izvi zvinofungwa. Rondedzero inotevera inowanzo shandiswa muindasitiri yekuvaka kusarudza zvisimbiso.
