Injani indlela yokuphefumla impahla yangaphantsi ye-silicone?
Ukususela kwimpahla yayo eyahlukileyo kunye noyilo lwayo, iimpahla zangaphantsi ze-silicone ziye zatsala ingqalelo engakumbi kubathengi kwimarike kwiminyaka yakutshanje. Nangona kunjalo, abathengi abaninzi basenamathandabuzo malunga nokuphefumla kweiimpahla zangaphantsi zesiliconeEli nqaku liza kuxoxa ngokweenkcukacha ngeempawu zezinto ze-silicone, iindlela zokuvavanya ukuphefumla, ingxelo yabasebenzisi, kunye nendlela yokuphucula ukuphefumla, ukuze kuncedwe abathengi baqonde ngcono ukuphefumla kweengubo zangaphantsi ze-silicone.

1. Iimpawu zokuphefumla kwezinto ze-silicone
(I) Intshayelelo kwizinto zesilicone
I-Silicone yinto eyenziwe nge-polymer eyenziwe nge-silicon dioxide, enokuhambelana kakuhle kwezinto eziphilayo, ukumelana nobushushu obuphezulu, kunye nokumelana nokwaluphala. I-Silicone yahlulwe yangamacandelo amabini: i-silicone yendalo kunye ne-silicone engaphiliyo. I-silicone yendalo isetyenziswa kakhulu, ngakumbi kwizixhobo zonyango, kwiipakeji zokutya, kwiimveliso zokhathalelo lomntu, njl.
(II) Uhlalutyo lokuphefumla
Ukuphefumla kwe-silicone kuxhomekeke kakhulu kwisakhiwo sayo sangaphakathi seembobo. I-silicone engaphiliyo idla ngokuba neembobo eziphezulu, nto leyo evumela iimolekyuli zegesi ukuba zisasazeke kwiimbobo zayo zangaphakathi. Nangona kunjalo, ngenxa yamandla amakhulu e-intermolecular kunye neembobo ezimbalwa, i-silicone engaphiliyo ayinakuphefumla kakuhle. Ngokubanzi, ukungena komoya kwe-silicone kubi kunee-elastomers ezininzi ze-thermoplastic (ezifana ne-TPE), kodwa isengaphantsi kwezinto zelaphu zemveli.

2. Indlela yokuvavanya ukuvuleka komoya
(I) Umgangatho wovavanyo lokungangeni komoya
Uvavanyo lokuvunyelwa komoya yindlela ebalulekileyo yokuvavanya ukuvunyelwa komoya kwamalaphu, kwaye lubaluleke kakhulu kuyilo nasekukhetheni iingubo zangaphantsi zesilicone. Iindlela zovavanyo lokuvunyelwa komoya ezisetyenziswa rhoqo ziquka indlela yobunzima, indlela yokuhamba kunye nendlela yetanki yokufuma. Ezi ndlela zivavanya ukuvunyelwa komoya ngokulinganisa ubunzima okanye isantya sokuhamba komoya odlula kwilaphu ngexesha ngalinye.
(II) Amanyathelo ovavanyo
Xa sithatha i-GB/T 24218.15 njengomzekelo, amanyathelo athile ovavanyo lokuvunyelwa komoya ngala alandelayo:
Ukuthatha iisampulu: Khetha ngokungacwangciswanga iisampulu ezi-5 uze uzinqumle zibe yi-100mm×100mm ngobukhulu.
Lungisa isampuli: Beka isampuli kwindawo eqhelekileyo yomoya, isebenze ngokwe-GB/T 6529, kwaye ulungise ukufuma kwimeko elinganayo.
Faka isampuli: Beka isampuli entlokweni yovavanyo uze uyibambe ukuze uthintele ukuvuza kwegesi.
Lungisa ukuhamba komoya: Vula ipompo ye-vacuum kwaye ulungise ukuhamba komoya ude umahluko woxinzelelo ube yi-100Pa, 125Pa okanye 200Pa.
Funda ixabiso lokuvunyelwa komoya: Emva kokuba uxinzelelo luzinzile, funda ixabiso lokuvunyelwa komoya kwiilitha/isentimitha yesikwere isekhondi L/(cm)
2
⋅s).

(III) Iziphumo zovavanyo
Ngokweziphumo zovavanyo, ukungena komoya kwezinto ze-silicone kudla ngokuba kubi. Umzekelo, ii-silicone invisible bras azinawo umoya obibi ngenxa yezinto zazo. Ukunxiba ixesha elide kunokubangela iimpawu ezifana ne-erythema kunye nokurhawuzelelwa eluswini.

III. Ingxelo yomsebenzisi kunye namava okwenyani
(I) Ingxelo yomsebenzisi
Abasebenzisi abaninzi baxele ukuba nangona impahla yangaphantsi ye-silicone ineengenelo ezithile ngokubonakala kwayo kunye nokuthuthuzela, ukungena komoya okungena kakuhle yingxaki eqhelekileyo. Abanye abasebenzisi bathi emva kokunxiba impahla yangaphantsi ye-silicone ixesha elide, ulusu luthanda ukubila kwaye alunakukhutshelwa ngexesha, nto leyo ebangela ukuba umntu angonwabi kakhulu.
(II) Amava okwenyani
Ngokwenyani, ukungena kakuhle komoya kwiingubo zangaphantsi zesilicone kubonakala kakhulu kwezi zinto zilandelayo:
Ukunxiba ixesha elide: Xa unxibe impahla yangaphantsi ye-silicone ixesha elide, ulusu ludla ngokubila kwaye alunakukhutshelwa ngexesha, nto leyo ebangela ukuba ulusu lube manzi kwaye lurhawuzelele.
Ulusu ludibana: Izinto ze-silicone zisondelelene kakhulu nolusu, kodwa umoya awungeni kakuhle, nto leyo ebangela iingxaki zolusu.
Imiboniso yezemidlalo: Kwimidlalo okanye kwiindawo zokubila, ukungakwazi ukuphefumla kakuhle kwempahla yangaphantsi ye-silicone kubonakala kakhulu.

4. Izinto ezichaphazela ukuphefumla
(I) Iimpawu zezinto ezibonakalayo
Ukuphefumla kwezixhobo ze-silicone kuchaphazeleka kakhulu bulwakhiwo kunye nokuvuleka kwayo. I-silicone engaphiliyo ine-porosity ephezulu kunye nokuphefumla okuhle; ngelixa i-silicone engaphiliyo ine-pores ezimbalwa kunye nokuphefumla okubi.
(II) Ukuphuculwa koyilo
Nangona ukuphefumla kwezinto ze-silicone kuphantsi, le ngxaki inokupheliswa kancinci ngokuphucula uyilo. Umzekelo, ezinye iimpahla zangaphantsi ze-silicone zongeze imingxunya yokuphefumla okanye zasebenzisa isakhiwo esineengqimba ezininzi kuyilo ukuphucula ukuphefumla. Nangona kunjalo, isiphumo sale milinganiselo yokuphucula sisencinci kwaye asinakuyisombulula ngokupheleleyo ingxaki yokuphefumla.
(III) Izinto ezisingqongileyo
Izinto ezikwimeko-bume ezifana nobushushu kunye nokufuma zinokuchaphazela ukuphefumla kwempahla yangaphantsi ye-silicone. Kwindawo enobushushu obuphezulu kunye nokufuma okuphezulu, ukuphefumla kwempahla yangaphantsi ye-silicone kuya kuncipha ngakumbi, nto leyo ebangela ukuba iingxaki zolusu zibonakale ngakumbi.

5. Indlela yokuphucula ukuphefumla kwempahla yangaphantsi yesilicone
(I) Khetha izinto ezifanelekileyo
Xa ukhetha impahla yangaphantsi ye-silicone, ungabeka phambili iimveliso ezenziwe ngezinto ze-silicone ezingaphiliyo kuba zinokuphefumla kakuhle. Ukongeza, ezinye izinto ezintsha ze-silicone ziphucule ukuphefumla ngokuphucula ulwakhiwo lwe-molecular, olunokusetyenziswa njengesalathiso sokukhetha.
(II) Ukuphuculwa koyilo
Kwabavelisi, ukuphefumla kwempahla yangaphantsi ye-silicone kunokuphuculwa ngolu phuculo lulandelayo loyilo:
Ukwandisa imingxuma yokungenisa umoya: Ukongeza imingxuma yokungenisa umoya kwimpahla yangaphantsi yesilicone kunokuphucula ukuphefumla ngempumelelo.
Ulwakhiwo oluneeleya ezininzi: Ukusebenzisa uyilo lwesakhiwo esineeleya ezininzi kunye nokusebenzisa izixhobo ezinokuphefumla kakuhle kumaleya ophakathi kunokuphucula ukuphefumla ngokubanzi.
Ukulungisa ukulingana: Ukulungisa ngokufanelekileyo ukulingana kwempahla yangaphantsi ye-silicone ukuze kuthintelwe ukulingana kakhulu nolusu kunokunciphisa iingxaki zolusu.
(III) Iingcebiso zokusetyenziswa
Kubathengi, ezi ndlela zilandelayo zingasetyenziswa ukunciphisa iingxaki ezibangelwa kukungakwazi ukuphefumla ngokwaneleyo kwempahla yangaphantsi ye-silicone:
Lawula ixesha lokunxiba: Kuphephe ukunxiba impahla yangaphantsi yesilicone ixesha elide. Kucetyiswa ukuba ixesha lokunxiba lingadluli kwiiyure ezi-6 ngalo lonke ixesha.
Gcina icocekile kwaye yomile: Hlamba impahla yangaphantsi ye-silicone rhoqo kwaye uyigcine icocekile kwaye yomile ukunciphisa ukukhula kweebhaktheriya kunye neengxaki zesikhumba.
Khetha indawo efanelekileyo: Xa usenza umthambo okanye ubila kakhulu, zama ukuphepha ukusebenzisa impahla yangaphantsi yesilicone kwaye ukhethe impahla yangaphantsi yendabuko enokuphefumla ngcono.

VI. Isiphelo
Ekubeni impahla yayo yahlukile kwaye iyilwe ngendlela eyahlukileyo, impahla yangaphantsi ye-silicone ineengenelo ezithile ngenkangeleko kunye nentuthuzelo, kodwa ukuphefumla kakubi yingxaki engenakubethwa ngoyaba. Ngovavanyo lokuphefumla kunye nempendulo yabasebenzisi, kunokubonwa ukuba impahla yangaphantsi ye-silicone ineziphene ezicacileyo ekuphefumleni, kwaye ukunxiba ixesha elide kunokubangela iingxaki zesikhumba ngokulula. Nangona le ngxaki inokupheliswa kancinci ngokuphucula uyilo, isiphene sokuphefumla okunganelanga asinakusonjululwa ngokupheleleyo. Ke ngoko, xa bekhetha impahla yangaphantsi ye-silicone, abathengi kufuneka baqwalasele iingenelo kunye neengxaki zayo ngokupheleleyo kwaye benze ukhetho olufanelekileyo ngokusekelwe kwiimfuno zabo kunye neemeko zokusetyenziswa. Kwangaxeshanye, abavelisi kufuneka baqhubeke nokuphucula uyilo kunye nezinto zempahla yangaphantsi ye-silicone ukuphucula ukuphefumla kwayo kunye nentuthuzelo ukuhlangabezana neemfuno zabathengi.
