Silicone remubatanidzwa nokuti chakuvhuvhu kugadzira: michina nokurondedzerwa

Silicone remubatanidzwa chinhu yakanaka zvinhu nokuda kwezvifananidzo zvaAtemisi anoumba zvisaririra Lifecasting uye zvimwe zvinhu zvakaoma. Sezvo mvura latex, rinopa nyore, aichinja-chinja, mukuru kuvimbika chimiro. Uyewo kune mamwe zvakwakanakira - refu hwose uye kuramba mishonga uye manyowa. Ndiwo yakarumbidza mashoko pagadzirwe kwenguva refu siyana dzakaoma ivhu. Silicone anoumba nokuti varinamire chinogona kuitwa munguva shoma nguva kupfuura latex muforoma, kana ukashandisa catalysts "kutsanya". The chete drawback ndechokuti anodhura pane latex, uye kwete saka kwakavharwa nenyama, zvichitungamirira atsamwira uye kukuvadza.

Zvinoumba Silicone Material

Izvi zvinhu ine nesilicon namatidza ari muzasi uye Platinum anowedzera, izvo Inowedzera koukukutu.

Paaisika mhando uchishandisa silicone remubatanidzwa yakajeka, tsvuku, yero, chena uye mamwe mavara. The hardener anogona kunge akasiyana palette kana kuva Hauoneki.

Mushure nokusanganisa zvakamisa hurongwa maviri mumba tembiricha silicone sezvamunoita anova nesimba uye anova rubbery chitarisiko. Average nguva okurapa nokuti ruzhinji - pakati maawa 18-24, asi vachiomesa nguva inogona dzinokwanisa kuderedzwa nokushandisa mukuru-waivako catalysts.

Mhando silicone yeimwe

The inonyanya rabha yeimwe inoshandiswa kugadzira anoumba - ichi RTV, RTV-2 uye HTV. Kusiyana rabha RTV (kamuri tembiricha vulcanizing) silicone HTV kunoda solidification tembiricha mamiriro kwazvo 100 ° C.

Pakati pevaya pave silicone remubatanidzwa wose ari kuedza kuita zvakawanda silicones uye catalysts nedzimwe viscosity, ruvara uye nezvimwewo zvinhu.

Pane mapoka maviri chikuru RTV-silicones

1. Tin catalyzed silicones.

2. Silicones pamusoro Platinum catalysts.

Mumwe nomumwe wavo ine zvakanakira nekuipira. Tin-catalyzed silicones vanowanzova isingadhuri uye nyore kushandisa. Vane viscosity kubva pasi kusvikira unosvikirwa, saka chigadzirwa nokuyerera akapoteredza tsime. Kusiyana neizvi, Platinum woutsinye yeimwe vakawanda zvakasikwa, ndivo sarufa, tini, amines, vachangotanga kugadzirwa polyester, epoxy kana urethane rabha nyaya. Kunyange pashure unhani nyaya acrylic lacquer silicone remubatanidzwa chokuumba Platinum-Inoomesa pamberi sarufa maitiro pamwe tinny hukawanika. Izvi zvinoita kuti kukodzera kuti dzakawanda dzinongoitika zvinhu. Kunyange zvakadaro, pashure kuomesa, vane soro zvemakemikari, microbiological nokupisa nemishonga mano, uye kazhinji vanoramba kusanduka kwemakore akawanda. Mukusiyana, netini-catalyzed silicones vanowanzotevedzera kuva pfava pashure pemakore mashomanana kushandiswa uye kutanga Makakamura kana kukuvara. Nezvikonzero izvi, boka silicones gaba anowanzoshandiswa kushanda pasi vhoriyamu Kudzingwa. Uye Platinum rinoshandiswa kuti rinokosha, kunyanya akawanda.

chengetedzo nguva

silicones zhinji zvinogona kushandiswa zvinobudirira makore 5 kubva kutenga musi kana kuchengetwa zvakanaka mune chisimbiso midziyo vari inotonhorera, nzvimbo yakaoma. Zvisinei catalysts vanorasikirwa kushanda kwavo nokukurumidza, kunyange kana zvakanaka zvakachengetwa, vari kushandiswa mukati gore.

apo kushandisa

Silicone RTV-2 remubatanidzwa inoshandiswa pagadzirwe vakawanda makopi Zvidhori. Uyewo muri zvibereko polyester, epoxy Inogadzirwa nemasiridzi anobuda mumiti, namo, plaster, makenduru, matoyi, Sipo, etc.

Silicone remubatanidzwa "Pentelast" ndizvo zvokudya uye njodzi. Kunakisa ichi zvinhu ndechokuti kwazvo kuchinja uye asingauyi kukuvadza chigadzirwa panguva nokubviswa, kwakadaro rabha anoumba inogona kushandiswa kakawanda. Sezvo izvi silicone chikafu-mugiredhi ane Platinum anowedzera, naro unogona kuita silicone achitanga kuti nesuko achitanga kuti makeke uye muffinit, nemakeke uye nezvimwe confectionery zvigadzirwa.

Safety Note

The silicone remubatanidzwa yakachengeteka chigadzirwa odorless tichishandisa kana kushandiswa nemazvo, zvisinei kuti catalysts uye thickeners zvingava chepfu meso uye ganda Zvisinei, zvikamu izvi dzomuviri kudzivirirwa.

Procedure mukusika anoumba

• Pamusoro vaikopera mharidzo iri kucheneswa uye degreased. Kana zvakakodzera, kuti mafuta akashandisa wakisi, mumwe sipo kugadzirisa kana petrolatum.

• The acho yakavhenganiswa kwazvo, sezvo precipitate ingangoumbwa panguva okuchengetera.

• Pre-akagadzirira mudziyo muchakandwa nechepasi kuti pfungwa. Saka mugaba kunogona mukombe mapurasitiki, nehomo kana bhokisi. Zvinofanira kuva vashoma yakarurama nechepasi uye mativi pasina makatsemuka uye maburi.

• In mudziyo rakasanganiswa yakachena hwaro uye hardener kusvikira homogeneous guru.

• Kuti kufungidzira uwandu silicone zvaida, unofanira kuverenga vhoriyamu akadurura, zvokuti chigadzirwa yave yakafukidzirwa. Munogonawo - unogona chete kufukidza pemvura chigadzirwa, pamwe maburi uye in, pashure koukukutu ari silicone kuti zadza mamwe mugove, muchiitiko ichi silicone uye akaponesa mari. Kuti noruvara kufukidza chiratidzazvizhinji, zviri chinodiwa kudira silicone kana kushandiswa maviri kana kupfuura mapati. The pati wechipiri iri rakaiswa pamusoro Rakasimbisa pakutanga, asi achiri Sticky. Unogonawo kushandisa gauze kana zvimwe muedzo zvinhu kuti midzi pakati akaturikidzana, iyo inoita kuti pave hwakasimba chimiro.

• The catalysts vakanga kusanganiswa kukura zvichienderana norudzi silicone. Vamwe vavo vanoshandisa napamaruva tiwedzere nhamba 50:50. Kurunga inogona mechanically kana manually ane chipunu kana chimuti. Mumwe haagoni kuwana zvematongerwo refu izvi haisi anopfuura 2 maminitsi, saka chero bedzi muitiro unobereka yakawanda mhepo matema iri musanganiswa. Kuti azive kana yunifomu kusachinja-chinja zvakaguma, nani kutora ruvara hardener.

• Mushure vakasvikapowo musanganiswa uchidururwa nokukurumidza sezvinobvira. The acho anorapa munhu rubbery ezvinhu mumaawa 24. At kutonhora pazasi +23 ° C marongero nguva ichava refu.

Chii chaunofanira kufunga

Air matema zvingaderedzwa kuti chinhu, kana kuti kutanga kunovhengana diki mugove wemisanganiswa uye kushandisa bhurasho, mharidzo kuifukidza. Saka, kukanzura kunokwanisika kwete chete matema asiwo Kujeka rehurukuro chimiro. Pashure kuiisa nhete paiva chigadzirwa kusiya ndakazorora pa nzvimbo tembiricha kusvikira, kusvikira musanganiswa akasununguka kubva mhepo uye haangazvidembi kuomesa. Zvadaro kusanganisa mugove vasara hardener pamwe nechigadziko uye iiswe akaturikidzana pamusoro zvigadzirwa kusvika rapera chimiro. Under Murabhoritari mamiriro, iyi nyore, sezvo zvinoitwa tichibatsirwa michina kuti zunzai Foroma akadururira uye kusunungura mhepo. In ezvinhu pevhu zvinogona kuzungunuswa, nokuzvidzora tapping pemvura.

Kana mharidzo ine rwokuzvarwa miganhu kudzivisa kupararira silicone panguva kudira, zvichaita zvakafanira kuvaka imwe ukaramba rusvingo rwakapoteredza mharidzo. Izvi zvinogona kuitwa kushandisa chero inert zvinhu zvakadai huni mapuranga, mapuranga, makadhibhokisi, etc. Simbisa unamire mugaba rusvingo achishandisa namira tepi kuti silicone hazvirevi achigarira maoko kubudikidza mutswe.

Yambiro! Mamwe silicone anogona rakabuda ruvara zvishoma, dzimwe mhando mabwe umo imwe Foroma anoitwa. basa riri pamberi aronga kuedza uye yokuzvionera vaine kunyora nezvavo mharidzo vasati kuvashandisa zvinhu zvinokosha.
