Munguva ichangopfuura, Steven akagamuchira mhinduro kubva kune vamwe vatengi: simba rako rekunamatira harina kunaka, harina kusimba, richava rakamonana mushure meusiku humwe.Unhu hwekunamatira hauna kunaka here?

Pakutanga, Steven anofunga kuti kugadzirwa kwefekitari hakuna kuomarara, chiyero hachina kukwana. Pane imwe nguva, fekitori yakavharwa kuti iongororwe. Fungisisa kuti nei zvakadaro.

Nekuitika kwedambudziko rerudzi urwu munguva pfupi yapfuura, uye kuganhurwa kudzimba shoma dzekudhinda kuti dzioneke, mutengi kugadzira bhodhoro rekutakura. Uye izvo zvakaita kuti ndifunge.

 

Kutanga, ngationgororei mhosva: kunamatira

Kuumbwa kwekunamira kunowanzo kupatsanurwa kuita marudzi maviri: Mvura inonamira B inopisa inonyunguduka inonamira.

Gluu yemvura, zvisina basa kutaura, imhando yemvura seyakanyungudika kana dispersion medium glue, iyo glue yekutanga kunamatira haina kunaka, ndiyo yaunodaidza kuti sticker pakutanga haina kusimba zvakanyanya, izvi zvinokonzerwa nehunhu hweglue, iyo glue haina kusimba zvakanyanya pakutanga, asi nekukura kwenguva, iyo label ichawedzera uye yakasimba, iyo yakareba, inowedzera viscous.

Kupisa kunyunguduka adhesive, yekare kudhinda vanhu vanofanira kuziva zviri nani kupfuura ini, imhando yepurasitiki inonamira, kune imwe tembiricha siyana ine tembiricha shanduko uye chinja mamiriro ayo emuviri, yakashandiswa iyi glue zvinyorwa, yakasimba yekutanga adhesion, batanidza ndiko kutanga kwakasimba kwazvo, asi nekuwedzera kwekushisa uye nguva, viscosity zvishoma nezvishoma inova isina simba, guruu iri rinokanganiswa nekupisa uye nguva.

Saka, imhaka yekuti ndashandisa chitupa-chemvura, chinoita kuti zita racho risanamire zvakakwana?

Muchokwadi, hazvina chokwadi, ngatitarisei, ndeipi iyo mamiriro ese eiyo label viscosity haina kukwana, nyaya yechiyero?

1. Mabhodhoro epurasitiki.

Kazhinji sarudza manyorero emakasitoma vatengi, vagadziri, epurasitiki jekiseni kuumba, pasi pemutsetse wekugadzira, yave kuda kutanga kunyora.

Ngatitarisei kemikari yakakosha mukugadzirwa kwejekiseni-yakaumbwa mabhodhoro epurasitiki: Release agent.

Chii chinoburitsa mumiririri?

Icho chinhu chinoshanda pakati pe mold uye chigadzirwa chakapedzwa.Kusunungura mishonga inopesana nemakemikari uye haiputi mukubatana nemakemikari ezvikamu zvakasiyana-siyana, kunyanya styrene uye amines.

Zvivakwa: Iyo yekubatanidza yakatarisana yakasungirirwa kune maviri maficha anonamira nyore kune mumwe nemumwe. Inoita kuti nzvimbo dzive nyore kubvisa, dzakatsetseka uye dzakachena.

2, varnish

Iyo inozivikanwawo sekuti kupi mvura, resin ndiyo huru yefirimu zvinhu pamwe nekunyungudutsa kwekuumbwa kwepende.Nekuti coating uye besmear zviri pachena, zvakare danai transparent coating maererano.Inoputirwa pamusoro pechinhu, yakaoma kuti iite firimu yakatsetseka, ratidza pamusoro pekugadzirwa kwepakutanga.

Properties: Mutsetse wekudzivirira wakatsetseka pamusoro pechinhu.

3. Vamwe

Zvigadzirwa zvakapedzwa zvichangobva kudhindwa zvichapfapfaidzwa netalcum poda uye zvimwe zvinhu, senge fekitori kabati ichapfapfaidzwa nemafuta ekudzivirira mhinduro.

Mamiriro aya achaonekwa anonamira paste haana kusimba.

Mushonga wemakemikari weglue kazhinji une vinyl acetate, varnish kana mumiririri wekusunungura kazhinji ane xylene uye silicone mafuta.Chimwe chezvikamu izvi chichaputsa glue, uye chimwe chacho hachizoiti nazvo.Kuwedzera kunofanira kuiswa pamusoro pechinhu pane imwe guruva kana mvura inodzivirira, kuitira kuti kunamatira uye chinhu chacho hachikwanisi kunyatsogadzirisa.

Pakaonekwawo dambudziko ratinogara tichinetsekana: chinamira hachinamira

Saka toita sei nemamiriro ezvinhu aya?

Zviri nyore: kuchenesa pamusoro.
