Injani indlela yokuphefumula yezingubo zangaphansi ze-silicone?
Kusukela ezintweni zayo ezihlukile kanye nomklamo wayo, izingubo zangaphansi ze-silicone zidonsele ukunaka okwengeziwe kubathengi emakethe eminyakeni yamuva nje. Kodwa-ke, abathengi abaningi basenokungabaza ngokuphefumuleka kwe-izingubo zangaphansi ze-siliconeLesi sihloko sizoxoxa ngokuningiliziwe ngezici zezinto ze-silicone, izindlela zokuhlola ukuphefumula, impendulo yomsebenzisi, nokuthi ungathuthukisa kanjani ukuphefumula, ukuze kusizwe abathengi baqonde kangcono ukuphefumula kwezingubo zangaphansi ze-silicone.

1. Izici zokuphefumula kwezinto ze-silicone
(I) Isingeniso ezintweni ze-silicone
I-Silicone iyinto eyenziwe nge-polymer eyenziwe nge-silicon dioxide, ekwazi ukuhambisana kahle kwezinto eziphilayo, ukumelana nokushisa okuphezulu, kanye nokumelana nokuguga. I-Silicone ihlukaniswe ngezigaba ezimbili: i-silicone ephilayo kanye ne-silicone engaphili. I-silicone engokwemvelo isetshenziswa kabanzi, ikakhulukazi kumadivayisi ezokwelapha, emaphaketheni okudla, emikhiqizweni yokunakekelwa komuntu siqu, njll.
(II) Ukuhlaziywa kokuphefumula
Ukukwazi ukuphefumula kwe-silicone kuncike kakhulu ekwakhiweni kwayo kwangaphakathi kwembobo. I-silicone engaphili ngokuvamile inembobo ephezulu, evumela ama-molecule egesi ukuthi asakazeke ngama-micropores ayo angaphakathi. Kodwa-ke, ngenxa yamandla amakhulu aphakathi kwama-molecule kanye nama-pores ambalwa, i-silicone engaphili ingakwazi ukuphefumula kahle. Ngokuvamile, ukungena komoya kwe-silicone kubi kakhulu kune-elastomers eziningi ze-thermoplastic (njenge-TPE), kodwa kusengaphansi kwezinto zendwangu zendabuko.

2. Indlela yokuhlola ukuvuleka komoya
(I) Izinga lokuhlola ukuvuleka komoya
Ukuhlolwa kokungena komoya kuyindlela ebalulekile yokuhlola ukungena komoya kwezindwangu, futhi kubaluleke kakhulu ekwakhiweni nasekukhethweni kwezingubo zangaphansi ze-silicone. Izindlela zokuhlola ukungena komoya ezisetshenziswa kakhulu zifaka phakathi indlela yobuningi, indlela yokugeleza kanye nendlela yethangi lomswakama. Lezi zindlela zihlola ukungena komoya ngokulinganisa isisindo noma izinga lokugeleza komoya odlula endwangu ngesikhathi ngasinye.
(II) Izinyathelo zokuhlola
Uma sithatha i-GB/T 24218.15 njengesibonelo, izinyathelo ezithile zokuhlolwa kokungena komoya yilezi ezilandelayo:
Ukusampula: Khetha amasampula ama-5 ngokungahleliwe bese uwasika abe usayizi ongu-100mm×100mm.
Lungisa isampula: Beka isampula endaweni evamile yomoya, sebenzisa ngokwe-GB/T 6529, bese ulungisa umswakama ube sesimweni esilinganiselayo.
Faka isampula: Beka isampula ekhanda lokuhlola bese ulibopha ukuze uvimbele ukuvuza kwegesi.
Lungisa ukugeleza komoya: Vula iphampu ye-vacuum bese ulungisa ukugeleza komoya kuze kube yilapho umehluko wokucindezela u-100Pa, 125Pa noma 200Pa.
Funda inani lokuvunyelwa komoya: Ngemva kokuba ingcindezi isizinzile, funda inani lokuvunyelwa komoya ngamalitha/isentimitha lesikwele isekhondi L/(cm)
2
⋅s).

(III) Imiphumela yokuhlolwa
Ngokwemiphumela yokuhlolwa, ukungena komoya kwezinto ze-silicone ngokuvamile kubi. Isibonelo, ama-bra angabonakali e-silicone anokungena komoya okubi ngenxa yezinto zawo. Ukugqoka isikhathi eside kungabangela izimpawu ezifana ne-erythema kanye nokulunywa esikhumbeni.

III. Impendulo yomsebenzisi kanye nolwazi lwangempela
(I) Impendulo yomsebenzisi
Abasebenzisi abaningi babike ukuthi nakuba izingubo zangaphansi ze-silicone zinezinzuzo ezithile ngokubukeka nangokududuzeka, ukungena kahle komoya kuyinkinga evamile. Abanye abasebenzisi bathi ngemva kokugqoka izingubo zangaphansi ze-silicone isikhathi eside, isikhumba sivame ukujuluka futhi asikwazi ukuphuma ngesikhathi, okubangela ukungakhululeki okukhulu.
(II) Okuhlangenwe nakho kwangempela
Ngokwesipiliyoni sangempela, ukungena kahle komoya kwezingubo zangaphansi ze-silicone kubonakala kakhulu kulezi zici ezilandelayo:
Ukugqoka isikhathi eside: Uma ugqoke izingubo zangaphansi ze-silicone isikhathi eside, isikhumba sivame ukujuluka futhi asikwazi ukuphuma ngesikhathi, okuholela esikhumbeni esimanzi nesilumayo.
Ukuthintana kwesikhumba: Izinto ze-silicone zisondelene nesikhumba, kodwa ukungena komoya akukuhle, okulula ukubangela izinkinga zesikhumba.
Izigcawu zemidlalo: Ezigcawini zemidlalo noma zokujuluka, ukuntuleka kokuphefumula kwezingubo zangaphansi ze-silicone kusobala kakhulu.

4. Izici ezithinta ukukwazi ukuphefumula
(I) Izakhiwo zezinto ezibonakalayo
Ukukwazi ukuphefumula kwezinto ze-silicone kuthinteka kakhulu yisakhiwo sayo sama-molecule kanye nokuvuleka. I-silicone engaphili inezimbobo eziphezulu kanye nokuvuleka okuhle; kuyilapho i-silicone engaphili inezimbobo ezimbalwa kanye nokuvuleka okubi.
(II) Ukuthuthukiswa komklamo
Nakuba ukuphefumula kwezinto ze-silicone kuphansi, le nkinga ingancishiswa kancane ngokuthuthukiswa komklamo. Isibonelo, ezinye izingubo zangaphansi ze-silicone zinezimbobo zokuphefumula noma zasebenzisa isakhiwo esinezingqimba eziningi ekwakhiweni ukuze kuthuthukiswe ukuphefumula. Kodwa-ke, umphumela walezi zinyathelo zokuthuthukisa usalinganiselwe futhi awukwazi ukuxazulula ngokuphelele inkinga yokuphefumula.
(III) Izici zemvelo
Izici zemvelo ezifana nokushisa nomswakama nazo zingathinta ukuphefumula kwezingubo zangaphansi ze-silicone. Endaweni enokushisa okuphezulu nomswakama ophezulu, ukuphefumula kwezingubo zangaphansi ze-silicone kuzoncipha kakhulu, okubangela izinkinga zesikhumba zibe zivelele kakhulu.

5. Indlela yokuthuthukisa ukuphefumula kwezingubo zangaphansi ze-silicone
(I) Khetha izinto ezifanele
Uma ukhetha izingubo zangaphansi ze-silicone, ungabeka phambili imikhiqizo eyenziwe ngezinto ze-silicone ezingaphili ngoba zinokuphefumula okuhle. Ngaphezu kwalokho, ezinye izinto ezintsha ze-silicone zithuthukise ukuphefumula ngokuthuthukisa isakhiwo sama-molecule, esingasetshenziswa futhi njengereferensi yokukhetha.
(II) Ukuthuthukiswa komklamo
Kwabakhiqizi, ukuphefumula kwezingubo zangaphansi ze-silicone kungathuthukiswa ngokusebenzisa ukuthuthukiswa komklamo okulandelayo:
Ukwandisa imigodi yokungenisa umoya: Ukufaka imigodi yokungenisa umoya ezimpahleni zangaphansi ze-silicone kungathuthukisa ukuphefumula ngempumelelo.
Isakhiwo esinezingqimba eziningi: Ukusebenzisa umklamo wesakhiwo esinezingqimba eziningi nokusebenzisa izinto ezikwazi ukuphefumula kahle ongqimbeni oluphakathi kungathuthukisa ukuphefumula okuphelele.
Ukulungisa ukulingana: Ukulungisa kahle ukulingana kwezingubo zangaphansi ze-silicone ukuze ugweme ukulingana kakhulu esikhumbeni kunganciphisa izinkinga zesikhumba.
(III) Iziphakamiso zokusetshenziswa
Kubathengi, izindlela ezilandelayo zingasetshenziswa ukunciphisa izinkinga ezibangelwa ukungaphefumuli kahle kwezingubo zangaphansi ze-silicone:
Lawula isikhathi sokugqoka: Gwema ukugqoka izingubo zangaphansi ze-silicone isikhathi eside. Kunconywa ukuthi isikhathi sokugqoka akufanele sidlule amahora ayi-6 isikhathi ngasinye.
Gcina ihlanzekile futhi yomile: Geza izingubo zangaphansi ze-silicone njalo futhi uzigcine zihlanzekile futhi zomile ukuze unciphise ukukhula kwamagciwane nezinkinga zesikhumba.
Khetha indawo efanele: Uma uzivocavoca noma ujuluka kakhulu, zama ukugwema ukusebenzisa izingubo zangaphansi ze-silicone bese ukhetha izingubo zangaphansi zendabuko ezikwazi ukuphefumula kangcono.

VI. Isiphetho
Njengoba ihlukile futhi iklanywe ngendlela ehlukile, izingubo zangaphansi ze-silicone zinezinzuzo ezithile ngokubukeka kwayo kanye nenduduzo, kodwa ukungaphefumuli kahle kuyinkinga engenakuzinakwa. Ngokuhlolwa kokungaphefumuli kahle kanye nempendulo yabasebenzisi, kungabonakala ukuthi izingubo zangaphansi ze-silicone zinezinkinga ezisobala zokungabi namandla okuphefumula, futhi ukugqoka isikhathi eside kungabangela izinkinga zesikhumba kalula. Nakuba le nkinga ingancishiswa kancane ngokuthuthukiswa komklamo, iphutha lokungaphefumuli kahle alinakuxazululwa ngokuphelele. Ngakho-ke, lapho bekhetha izingubo zangaphansi ze-silicone, abathengi kufanele bacabangele izinzuzo nezinkinga zazo ngokuphelele futhi benze izinqumo ezifanele ngokusekelwe ezidingweni zabo kanye nezimo zokusetshenziswa. Ngesikhathi esifanayo, abakhiqizi kufanele baqhubeke nokuthuthukisa umklamo kanye nezinto zezingubo zangaphansi ze-silicone ukuze bathuthukise ukungaphefumuli kahle kanye nenduduzo ukuze kuhlangatshezwane nezidingo zabathengi.
