Mhinduro:

Kutsvuka kwesilicone sealant isina kujeka kunokonzerwa nekusakwana kwesealant pachayo, kunyanya nekuda kwechinhu chinobatanidza uye chinogozha chiri mu neutral sealant. Chikonzero ndechekuti zvinhu zviviri izvi zvine "amino groups", izvo zvinogona kutsvuka zvakanyanya. Mazhinji emhando dzesilicone sealants ane mukurumbira anotengeswa kunze kwenyika anewo chiitiko ichi chekutsvuka.

Pamusoro pezvo, kana neutral transparent silicone sealant ikashandiswa panguva imwe chete neacetic silicone sealant, inogona kukonzera kuti neutral sealant iite yero mushure mekuoma. Izvi zvinogonawo kukonzerwa nenguva yakareba yekuchengetedza kwesealant kana kuti kusangana pakati pesealant ne substrate.

Mhinduro:

Alkoxy cured type neutral silicone sealant inogona kunge iine chiitiko ichi nekuda kwekugadzirwa kwezvinhu zvisina kuchena zve titanium chromium compound. Titanium chromium compound pachayo yakatsvuka, uye ruvara ruchena rwesealant runowanikwa ne titanium dioxide powder iri musealant ichishanda se colorant.

Zvisinei, sealant chinhu chinobva muzvinhu zvipenyu, uye maitiro mazhinji emakemikari ezvemakemikari anogona kudzoserwa kumashure, uye maitiro ekunze anoitika. Kupisa ndiko kunokonzera maitiro aya. Kana tembiricha yakwira, maitiro akanaka neasina kunaka anoitika, zvichikonzera shanduko dzemavara. Asi mushure mekunge tembiricha yadzikira uye yagadzikana, maitiro acho anodzokera kumashure uye ruvara runodzokera pamamiriro arwo epakutanga.

Mhinduro:

Izvi zvinofanirawo kukonzerwa nedambudziko rekusarudza uye kusimbiswa kwezvinhu zvisina kugadzirwa. Zvimwe zvigadzirwa zvemumba zvinopenya zvine mapurasitiki anokurumidza kupfava, nepo zvimwe zvine mafiller akawanda anowedzera simba. Kana mapurasitiki achipfava, sealant inodzikira uye inotambanuka, zvichiratidza ruvara rwemafiller (mafiller ese ari mu neutral sealant ane ruvara ruchena).

Zvivharo zvine mavara zvinogadzirwa nekuwedzera pigments kuti zvive nemavara akasiyana. Kana paine matambudziko nekusarudza pigment, ruvara rwechivharo runogona kuchinja mushure mekushandisa. Neimwe nzira, kana zvivharo zvine mavara zvikaiswa zvakatetepa panguva yekuvaka, kuderera kwechinhu chinovharo panguva yekuchenesa kunogona kukonzera kuti ruvara ruve ruchena. Muchiitiko ichi, zvinokurudzirwa kuchengetedza ukobvu hwakati (pamusoro pe3mm) pakushandisa chivharo.

Mubvunzo wechina.Sei mavanga kana zvisaririra zvichionekwa pagirazi mushure mekushandisa silicone sealant kumusana kwenguva?

Mhinduro:

Kazhinji kune mhando nhatu dzekuputira kumashure kwemagirazi dziri kutengeswa: mercury, pure silver, uye copper.

Kazhinji, mushure mekushandisa silicone sealant kuisa magirazi kwenguva yakati, pamusoro pegirazi panogona kunge paine mavanga. Izvi zvinowanzo kukonzerwa nekushandisa acetic silicone sealant, iyo inosangana nezvinhu zvataurwa pamusoro apa uye inokonzera mavanga pamusoro pegirazi. Nokudaro, tinosimbisa kushandiswa kwe neutral sealant, iyo yakakamurwa kuita mhando mbiri: alkoxy ne oxime.

Kana girazi rine mhangura rakaiswa ne oxime neutral sealant, oxime ichaora zvinhu zvemhangura zvishoma. Mushure menguva yekuvakwa, pachava nemavanga ekuora kumashure kwegirazi panoiswa sealant. Zvisinei, kana alkoxy neutral sealant ikashandiswa, chiitiko ichi hachizoitiki.

Zvese zviri pamusoro apa zvinokonzerwa nekusasarudzwa kwezvinhu zvisina kunaka kunokonzerwa nekusiyana kwezvikamu zvepasi. Saka, zvinokurudzirwa kuti vashandisi vaite bvunzo yekuenderana vasati vashandisa chivharo kuti vaone kana chivharo ichi chinoenderana nezvinhu zvacho.

Mubvunzo wechisere.Sei mamwe ma silicone sealant asina kusimba akaiswa panosangana mahwindo ekongiri nesimbi achigadzira mabubbles akawanda mushure mekuoma muzhizha, nepo mamwe asingadaro? Idambudziko remhando here? Sei zvinhu zvakafanana zvisina kumboitika kare?

Mhinduro:

Mhando zhinji dzesilicone sealant dzisina kusimba dzakambosangana nedambudziko rakafanana, asi harisi dambudziko remhando yepamusoro. Neutral sealants inouya mumhando mbiri: alkoxy ne oxime. Uye alkoxy sealants inoburitsa gasi (methanol) panguva yekuoma (methanol inotanga kupwanyika panosvika 50℃), kunyanya kana yakatarisana nezuva rakananga kana tembiricha yakakwira.

Pamusoro pezvo, mahwindo ekongiri nesimbi haapindi mhepo zvakanyanya, uye muzhizha, kana tembiricha neunyoro zvakwira, sealant inopora nekukurumidza. Gasi rinoburitswa kubva musealant rinogona kungobuda kubva muchikamu chesealant chakacheneswa zvishoma, zvichiita kuti mabubbles ehukuru hwakasiyana aoneke pasealant yakacheneswa. Zvisinei, oxime neutral sealant haiburitse gasi panguva yekupisa, saka haiburitse mabubbles.

Asi dambudziko re oxime neutral silicone sealant nderekuti kana tekinoroji uye fomura yacho zvikasabatwa nemazvo, inogona kutetepa nekutsemuka panguva yekucheneswa kwayo munguva yechando.

Kare, zvinhu zvakafanana zvaisaitika nekuti silicone sealants yaisawanzoshandiswa munzvimbo dzakadaro nemayuniti ekuvaka, uye zvinhu zve acrylic zvisingapindi mvura zvaiwanzoshandiswa panzvimbo iyoyo. Saka, chiitiko chekuputira mu silicone neutral sealant chakanga chisina kuwanda. Mumakore achangopfuura, kushandiswa kwesilicone sealants kwave kuchipararira zvishoma nezvishoma, zvichivandudza zvikuru mwero wehunhu hweinjiniya, asi nekuda kwekusanzwisisa hunhu hwezvinhu, kusarudzwa kwezvinhu zvisina kunaka kwakakonzera chiitiko chekuputira sealant.
