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, hazvina basa kutaura, imhando ine mvura se solvent kana dispersion medium glue, glue yekutanga adhesion haina kunaka, ndiyo yaunoti sticker pakutanga haina kusimba zvakanyanya, izvi zvinokonzerwa nehunhu hweglue. , glue haina kusimba zvakanyanya pakutanga, asi nekuvandudzwa kwenguva, iyo label ichava yakasimba 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, yakashandisa iyi glue mavara, yakasimba yekutanga adhesion, batanidza ndiko kutanga. yakasimba kwazvo, asi nekuwedzera kwekushisa uye nguva, viscosity zvishoma nezvishoma inova isina simba, iyi glue inokonzerwa nekushisa 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.Kusunungurwa kwemishonga inopesana nemakemikari uye haiputi mukubatana nemakemikari ezvikamu zvakasiyana-siyana, kunyanya styrene uye amines. kuora kana kupfeka;

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

2, varnish

Iyo inozivikanwawo sekuti pane mvura, resin ndiyo main film material plus solvent composition of the peint.Nekuti coating and besmear is transparent, also call transparent coating accordingly.Yakavharwa pamusoro pechinhu, yakaoma kuita firimu rakatsetseka, ratidza nzvimbo. yezvinyorwa zvepakutanga.

Properties: Mutsetse wekudzivirira wakatsetseka pamusoro pechinhu.

3. Vamwe

Zvigadzirwa zvakapedzwa zvakangodhindwa zvichapfapfaidzwa netalcum poda uye zvimwe zvinhu, senge fekitori kabhineti inozopfapfaidzwa nemafuta ekudzivirira mhinduro.

Aya mamiriro 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 hachizoiti nazvo.Kuwedzera kunofanira kuiswa pamusoro. chechinhu pane imwe guruva kana mvura inodzivirira, kuitira kuti chigadziro uye chinhu chisakwanise kunamatira zvakakwana.

Pakaonekwawo dambudziko ratinogara tichinetsekana: sticker not sticky

Saka toita sei nemamiriro ezvinhu aya?

Zviri nyore: kuchenesa pamusoro.
