Q1.Chii chikonzero chekusarerekera pachena silicone sealant ichichinja yero?

Mhinduro:

Iyo yero yekusarerekera yakajeka silicone sealant inokonzerwa nekukanganisa mune sealant pachayo, kunyanya nekuda kweiyo muchinjiko-inobatanidza mumiriri uye thickener mune yaakarerekera sealant.Chikonzero ndechekuti zvinhu zviviri izvi zvakasvibirira zvine "mapoka emaamino", ayo anonyanya kutapukirwa neyero.Mazhinji anotengeswa kunze ane mukurumbira brand silicone sealants zvakare ane iyi yero chiitiko.

Uye zvakare, kana kusarerekera kwakajeka silicone sealant kuchishandiswa panguva imwe chete seacetic silicone sealant, inogona kukonzera iyo yakasarudzika sealant kushanduka yero mushure mekurapa.Inogonawo kukonzerwa nekureba kwenguva yekuchengetedza kwechisimbiso kana kuita pakati pechisimbiso uye substrate.

Q2.Sei neutral silicone sealant chena ruvara dzimwe nguva ichichinja pink?Imwe sealant inodzokera kuchena vhiki mushure mekurapa?

Mhinduro:

Alkoxy yakarapwa rudzi rwakarerekera silicone sealant inogona kunge iine chiitiko ichi nekuda kwekugadzira mbishi zvinhu titanium chromium compound.Titanium chromium compound pachayo yakatsvuka, uye ruvara ruchena rwechisimbiso runowanikwa netitanium dioxide poda mune sealant ichiita seruvara.

Nekudaro, sealant chinhu che organic, uye akawanda organic kemikari maitiro anodzorereka, nedivi maitiro anoitika.Tembiricha ndiyo kiyi yekukonzeresa maitiro aya.Kana kutonhora kuchikwira, maitiro akanaka uye asina kunaka anoitika, zvichiita kuti ruvara ruchinje.Asi mushure mekunge tembiricha yadzikira uye yadzikama, maitiro anodzokera kumashure uye ruvara runodzokera kune hwaro hwepakutanga.Iine yakanaka yekugadzira tekinoroji uye formula mastery, chiitiko ichi chinofanirwa kudzivirirwa.

Q3.Nei chimwe chigadzirwa chemukati chakajeka chisimbiso chichichinja ruvara ruchena mushure memazuva mashanu ekushandisa?Nei isina kwayakarerekera yegirini sealant ichichinja chena ruvara mushure mekushandisa?

Mhinduro:

Izvi zvinofanirwawo kuverengerwa kudambudziko rekusarudzwa kwezvinhu zvakasvibiswa uye kusimbiswa.Chimwe chigadzirwa chemukati chakajeka sealant chine maplasticizer ari nyore kushanduka, nepo mamwe aine mamwe anosimbisa mafirita.Apo mapurasitiki anoputika, sealant inoderera uye inotambanudza, ichiratidza ruvara rwemafiritsi (ese mafiritsi mu neutral sealant akachena muvara).

Colored sealants inogadzirwa nekuwedzera pigment kuti iite mavara akasiyana.Kana pane matambudziko nekusarudza pigment, ruvara rwechisimbiso rinogona kuchinja mushure mekushanda.Neimwe nzira, kana zvisimbiso zvemavara zvakaiswa zvakatetepa zvakanyanya panguva yekuvaka, iyo yekuzvarwa shrinkage yechisimbiso panguva yekurapa inogona kuita kuti ruvara rureruke.Muchiitiko ichi, zvinokurudzirwa kuchengetedza humwe hukuru (pamusoro pe3mm) paunenge uchiisa chisimbiso.

Q4.Sei mavara kana maronda achionekwa pagirazi mushure mekushandisa silicone sealant kumusana kwenguva yenguva?

Mhinduro:

Iko kunowanzova nemhando nhatu dzejasi kumashure kwezvionioni pamusika: mercury, sirivha yakachena, uye mhangura.

Kazhinji, mushure mekushandisa silicone sealant kuisa magirazi kwenguva yakati, girazi repamusoro rinogona kunge riine mavara.Izvi zvinowanzokonzerwa nekushandisa acetic silicone sealant, iyo inopindirana nezvinhu zvataurwa pamusoro apa uye inokonzera mavara pachionioni.Nokudaro, tinosimbisa kushandiswa kwekusarerekera sealant, iyo yakakamurwa kuva marudzi maviri: alkoxy uye oxime.

Kana girazi rinotsigirwa nemhangura rakaiswa neoxime neutral sealant, oxime inosvibisa zvishoma zvinhu zvemhangura.Mushure menguva yekuvaka, pachava nemavara ekuora kumashure kwegirazi apo chisimbiso chinoshandiswa.Nekudaro, kana alkoxy neutral sealant ikashandiswa, chiitiko ichi hachizoitika.

Zvose zviri pamusoro apa zvinokonzerwa nekusarudzwa kwezvinhu zvisina kunaka kunokonzerwa nekusiyana kwe substrates.Naizvozvo, zvinokurudzirwa kuti vashandisi vaite bvunzo yekuenderana vasati vashandisa chisimbiso kuti vaone kana chisimbiso chichienderana nezvinhu.

Q5.Sei mamwe masilicone sealants achiita semagranules saizi yemakristasi emunyu kana aiswa, uye nei mamwe emagranules aya achinyungudika ega mushure mekurapa?

Mhinduro:

Iri idambudziko neraw material formula inoshandiswa pakusarudza iyo silicone sealant.Mamwe silicone sealanst ane cross-linking agents anogona kupenya pane tembiricha yakaderera, zvichiita kuti muchinjiko-wekubatanidza mumiriri uome mukati mebhodhoro rekunamira.Nekuda kweizvozvo, kana chinonamira chikaburitswa, magranules akafanana nemunyu ehukuru hwakasiyana anogona kuoneka, asi anonyungudika zvishoma nezvishoma nekufamba kwenguva, zvichiita kuti magranules angonyangarika panguva yekurapa.Iyi mamiriro haanyanyi kuita pamhando yesilicone sealant.Chikonzero chikuru chechiitiko ichi ndechekuita kwakakosha kwekudziya kwakaderera.

Q6.Ndezvipi zvikonzero zvinogoneka nei imwe inogadzirwa mudzimba silicone sealant yakaiswa pagirazi inotadza kurapa mushure memazuva manomwe?

Mhinduro:

Mamiriro ezvinhu aya anowanzoitika mumamiriro ekunze anotonhora.

1.Chisimbiso chinoshandiswa zvakanyanya, zvichiita kuti zvishoma nezvishoma kuporesa.

2.Nzvimbo yekuvaka inobatwa nemamiriro okunze akaipa.

3.Chisimbiso chapera kana chakaremara.

4.The sealant yakanyanyisa uye inonzwa isingakwanisi kuporesa.

Q7.Ndechipi chikonzero chemabhuru anooneka kana uchishandisa zvimwe zvemukati zvakagadzirwa silicone sealant zvigadzirwa?

Mhinduro:

Panogona kuva nezvikonzero zvitatu zvinobvira:

1.Tekinoroji isina kunaka panguva yekurongedza, zvichiita kuti mweya uvharwe mubhodhoro.

2.Vashoma vagadziri vasina kutendeseka nemaune havasimbise chivharo chepasi chechubhu, vachisiya mhepo muchubhu asi vachipa fungidziro yeakakwana silicone sealant volume.

3.Mamwe anogadzirwa mudzimba silicone sealants ane mafirita anogona kuita kemikari nePE purasitiki yakapfava yesilicone sealant packaging chubhu, zvichiita kuti chubhu yepurasitiki iwedzere uye kuwedzera pakureba.Nekuda kweizvozvo, mhepo inogona kupinda munzvimbo mukati mehubhu uye ichikonzera voids musilicone sealant, zvichikonzera kurira kwemabhuru panguva yekushandisa.Nzira inobudirira yekukunda chiitiko ichi kushandisa tube packaging uye kuterera kune nzvimbo yekuchengetedza yechigadzirwa (pasi pe30 ° C munzvimbo inotonhorera).

Q8.Nei mamwe masimbi asina kwaakarerekera esilicone akaiswa panosangana kongiri uye simbi mafirita emahwindo achigadzira mabhuru akawanda mushure mekurapa muzhizha, asi mamwe asingadaro?Inyaya yemhando here?Nei zvinhu zvakadaro zvisati zvaitika?

Mhinduro:

Mazhinji mabhureki e-neutral silicone sealant akawana zviitiko zvakafanana, asi haisi iyo nyaya yemhando.Neutral sealants inouya mumhando mbiri: alkoxy uye oxime.Uye ma alkoxy sealants anoburitsa gasi (methanol) panguva yekurapa (methanol inotanga kubuda pa50 ℃), kunyanya kana yakavhenekerwa nezuva rakananga kana tembiricha yakakwira.

Uye zvakare, kongiri uye simbi mahwindo mafuremu haanyanyi kupindira kumhepo, uye muzhizha, nepamusoro tembiricha uye hunyoro, chisimbiso chinorapa nekukurumidza.Iyo gasi yakaburitswa kubva kune sealant inogona chete kupukunyuka kubva pachikamu chakaporeswa chisimbiso, zvichiita kuti mabhuru ehukuru hwakasiyana aoneke pachisimbiso chakarapwa.Nekudaro, oxime neutral sealant haiburitse gasi panguva yekurapa, saka haiburitse mabhubhu.

Asi iyo yakashata yeoxime neutral silicone sealant ndeyekuti kana tekinoroji nekugadzira zvikasabatwa nemazvo, zvinogona kuderera nekutsemuka panguva yekurapa mukutonhora kwemamiriro ekunze.

Munguva yakapfuura, zvimwe zvakafanana zvaisaitika nekuti masilicone sealants aisawanzo shandiswa munzvimbo dzakadai nezvikamu zvekuvaka, uye acrylic zvisimbiso zvemvura zvaiwanzoshandiswa panzvimbo.Naizvozvo, chiitiko chekuputika musilicone neutral sealant chakanga chisina kunyanya kuwanda.Mumakore achangopfuura, kushandiswa kwesilicone sealants kwave kupararira zvishoma nezvishoma, zvichivandudza zvakanyanya chiyero chemhando yeinjiniya, asi nekuda kwekushaikwa kwekunzwisisa kwehunhu hwezvinhu, kusarudzwa kwezvinhu zvisina kufanira kwakatungamira kune chiitiko chekuputira sealant.

Q9.Nzira yekuita sei kuenzanisa kuongorora?

Mhinduro:

Kunyatsotaura, kuyedzwa kwekuenderana pakati peanonamira uye ma substrates ekuvaka anofanirwa kuitwa nemadhipatimendi emunyika anozivikanwa ekuongorora zvivakwa.Nekudaro, zvinogona kutora nguva yakareba uye zvichidhura kuwana mibairo kuburikidza nemadhipatimendi aya.

Pamapurojekiti anoda kuyedzwa kwakadaro, zvinodikanwa kuti utore gwaro rekuongorora kubva kusangano renyika rine mvumo yekuyedza usati wafunga kushandisa chimwe chigadzirwa chekuvaka.Kune mapurojekiti akajairwa, iyo substrate inogona kupihwa kune iyo silicone sealant inogadzira yekuenderana kuyedzwa.Mhedzisiro yekuyedza inogona kuwanikwa mukati memazuva makumi mana neshanu kune structural silicone sealant, uye mazuva makumi matatu nemashanu ekusarerekera uye acetic silicone sealant.
