Ungasarudza sei girazi sealant?

Girazi sealant chinhu chekubatanidza uye kuisa chisimbiso magirazi akasiyana kune mamwe ma substrates.

Kune marudzi maviri makuru echisimbiso: silicone sealant uye polyurethane sealant.

Silicone sealant - yatinowanzonzi girazi sealant, yakakamurwa kuva mhando mbiri: acidic uye kwazvakarerekera (neutral sealant inokamurwa kuva: stone sealant, chakuvhe-proof sealant, fireproof sealant, pombi sealant, etc.) . Kazhinji, girazi sealant inofanira kuva akashongedzerwa nepfuti inosunga kana uchiishandisa.Paunenge uchiishandisa, zviri nyore kuibvisa kubva mubhodhoro re sealant nepfuti yakavhara, uye nzvimbo yacho inogona kuderedzwa ne spatula kana huni huni.Kune marudzi akasiyana echisimbiso, kumhanya kwekuporesa kwakasiyanawo.Kazhinji, acid sealant uye isina kwayakajeka transparent sealant inofanirwa kuporeswa mukati me5-10 maminetsi, uye neutral variegated sealant inofanirwa kurapwa mukati memaminitsi makumi matatu.Nguva yekuporesa yegirazi sealant inowedzera sezvo kukora kwechisungo kunowedzera, uye nguva yekurapa inotarirwa nekuoma kwechisimbiso.

Zvakare, panguva yekurapa kweasidhi girazi sealant, kuvhurika kweacetic acid kunoburitsa kunhuhwirira, kunopera panguva yekurapa, uye hakuzove nekunhuhwirira kwakasarudzika mushure mekurapa, saka usanetseka kana kunhuwa kunogona. kubviswa.Paunosarudza, kwete kungotanga kubva pamutengo, asiwo enzanisa unhu.Uye pakusarudza girazi sealant, zvinoenderana nekuita kwako kunoenderana uye kushandisa.

1.Ndapota dusamhanye kutengagirazi sealant

Vamwe vatengi vakatenga girazi sealant vasinganzwisisi ruzivo rwekutanga rwechigadzirwa, uye vakawana matambudziko mazhinji mukuishandisa.Zvakadai se: ndeupi musiyano uripo pakati peasidhi sealant uye nearere sealant?Nei chete zvimiro zvinonamira zvichikwanisa kuwana chisungo chisungo pakati pegirazi?Sei mamwe magirazi sealant akajeka achichinja ruvara?Ndezvipi zvekuvaka zvinogona girazi sealant bond?nezvimwewo Kana iwe uchinzwisisa kurongeka, kushandiswa, kurambidzwa, nzira dzekushandisa uye nguva yekuchengetedza yegirazi sealant usati watenga, iwe unogona zvechokwadi kuchengetedza mari panguva yekuvaka, kuderedza rework panguva yekuvaka, uye kuwedzera hupenyu hwebasa regirazi sealant.

2.Ndapota dusatenga zvakachipagirazisealant

Kunyangwe girazi sealant yakashandiswa zvakanyanya mumapurojekiti ekuvaka kana kushongedza, vashandisi vazhinji (vamwe vashandisi vekare vakashandisa girazi sealant kwenguva yakareba) vachiri kuisa zvigadzirwa zvakachipa pakutanga.Chero bedzi iyo bato repurojekiti A risingatsanangure girazi sealant brand, sarudza Yakaderera-mutengo sealant haidzivisiki, asi kushandiswa kweiyo yakaderera-mutengo sealant haingokanganisa hutano uye hupenyu hwebasa reprojekiti, asi zvinonyanya kukosha, zvakanyanya. nyore kukonzeresa rework, kunonoka nguva yekuvaka, uye kutokonzera tsaona dzemhosva.Kuti vawane purofiti yakakura, vatengesi vasina kutendeseka vanogona kutamba manomano pakurongedza, kushandisa mabhodhoro akakora ekurongedza kuti vaderedze huremu hwesealant, uye kutsiva brand sealant neine yakaderera sealant.Mhindu huru yavanowana inobva pamutengo.Iyo yakaderera-giredhi giredhi sealant yehuremu hwakafanana inogona kudhura zvakapetwa katatu pane brand girazi sealant, asi viscosity uye tension yegirazi sealant ine simba rakapetwa 3-20 pane yakaderera-giredhi girazi sealant, uye hupenyu hwesevhisi ndeye 10-50. nguva refu.Naizvozvo, mainjiniya einjiniya haafanire kuchengetedza dambudziko, uye chete nekutenga kutenderedza vanogona kuve nechokwadi chemhando yeprojekiti;vatengi havafanirwe kukara zvakachipa, kuti varege kukanganisa hupenyu hwekushongedza kwemukati.

3.Kana iwe usingazive mashandiro egirazi sealant, usashandise upofu.

Kune akawanda marudzi egirazi sealant pamusika, anosanganisira acid girazi sealant, neutral weather-resistant sealant, silicic acid neutral structural sealant, silicone stone sealant, neutral anti-mildew sealant, hollow glass sealant, special sealant yealuminium-plastic panels, special sealant ye aquariums, special sealant yegirazi hombe, special sealant yekugezera anti-mildew, acid structural sealant, etc., vashandisi havanyatso nzwisisi hunhu hwekurongeka, kushanda, zvirambidzo zvekushandisa uye nzira dzekuvaka dzegirazi sealant, uye mazhinji acho. handina kumbochibata.Mamwe mayuniti kana vatengi vanoona girazi sealant se "universal sealant".Mushure megore, vanoona kuti nzvimbo inoshandiswa girazi sealant yakadonha kana kuchinja ruvara, saka vanoongorora kushanda kwegirazi sealant.Zvinoitika kuti zvinhu zvakasiyana-siyana zvekuvaka zvinoda kusarudza marudzi akasiyana egirazi.sealant.Naizvozvo, kwete neupofu kushandisa girazi sealant ndeimwe yemamiriro ekusarudza chigadzirwa chakakodzera.

4.Chenjerera kune zuva rekugadzira

Kuitwa kwezvinhu zvese zvegirazi rakapera sealant kunoderedzwa zvakanyanya.

5.Edza neruoko.

Bvisa chikamu chegirazi sealant inofashukira kubva kumucheto kwechivharo cherabha, pinza uye uikweve zvinyoronyoro nemaoko ako.Kana yakazara ne elasticity uye yakapfava, mhando yacho yakanaka.Kana iyo yakaoma zvishoma uye brittle, kunaka kwechisimbiso kunopokana.

6.After kupora zvakakwana

①Tarisa kupenya kwepamusoro.Iyo yakanyatsogadziriswa girazi sealant, iyo yakatsetseka uye yakatsetseka kupenya kwepamusoro, ndiko kunaka kwemhando.the

② Tarisa nzvimbo ye pores.Pores anoratidza kuti mhinduro haina kuenzana, uye panogona kunge paine dambudziko nefomula.the

③ Tarisa kana nzvimbo yacho ine mafuta.Kana paine kubuda kwemafuta, zvinoreva kuti kuti uderedze mutengo, mafuta machena akawandisa anowedzerwa uye mhando haina kunaka.

④ Tarisa uone hupfu pamusoro.Kana iri hupfu, pane chakaipa pakugadzira.the

⑤ Tarisa kunamatira.Bvisa girazi sealant pane substrate neruoko, kana inogona kubvarurwa nyore nyore, zvinoreva kuti kunamatira hakuna kukwana.Pane kudaro, igiredhi repamusoro.

⑥ Edza kuchinjika.Bvisa chikamu chegirazi sealant uye uchikwevera neruoko.Iyo elongation yegirazi yakanaka sealant inogona kusvika kaviri kana katatu yepakutanga.Mushure mekusunungura ruoko, runogona kudzokera kune kureba kwepakutanga.Iyo yakareba iyo elasticity yakachengetedzwa, zviri nani kunaka kwechisimbiso.Chengetedza ruvara kana uchikwevera kusvika kumuganhu, iyo idiki shanduko yeruvara, zviri nani kunaka.

⑦ Tarisa pane tsvina.Bucki girazi sealant nemaoko ako kusvika yatyoka, uye tarisa kuti mukati memukati wakareruka uye wakapfava.Iyo yakanyanya kuenzana uye yakatetepa mhando, zviri nani.the

⑧Tarisa kuramba ukuru.Iyo yakareba isingaite kuumbwa, zviri nani iyo sealant.

⑨Ona kana ichichinja ruvara.Iyo yakareba ruvara harushanduke kwenguva yakareba, zviri nani sealant.

⑩Kugadzikana kwehutano.Izvi zvinosanganisira zvinhu zvakawanda, zvinosanganisira kugadzira, zvigadzirwa, zvigadzirwa zvekugadzira uye kugadzikana kwenyanzvi dzekugadzira.Yakanaka girazi sealant inofanirwa kunge yakafanana kune yega batch yezvinhu.
