Kodi mpweya wabwino wa zovala zamkati za silicone ndi wotani?
Popeza zovala zake zapadera komanso kapangidwe kake, zovala zamkati za silicone zakopa chidwi cha ogula pamsika m'zaka zaposachedwa. Komabe, ogula ambiri akadali ndi kukayikira za momwe mpweya umapumirazovala zamkati za siliconeNkhaniyi ifotokoza mwatsatanetsatane za makhalidwe a zinthu za silicone, njira zoyesera kupuma bwino, ndemanga za ogwiritsa ntchito, komanso momwe angathandizire kuti mpweya ukhale wabwino, kuti athandize ogula kumvetsetsa bwino momwe zovala zamkati za silicone zimakhalira bwino.

1. Makhalidwe a zinthu za silikoni opumira mpweya
(I) Chiyambi cha zinthu za silicone
Silicone ndi chinthu chopangidwa ndi silicon dioxide, chomwe chimagwirizana bwino ndi zinthu zina, kutentha kwambiri, komanso kukalamba. Silicone imagawidwa m'magulu awiri: silicone yachilengedwe ndi silicone yopanda chilengedwe. Silicone yachilengedwe imagwiritsidwa ntchito kwambiri, makamaka pazida zamankhwala, ma CD a chakudya, zinthu zosamalira thupi, ndi zina zotero.
(II) Kusanthula momwe mpweya umayendera
Kupuma bwino kwa silicone kumadalira kwambiri kapangidwe ka ma pore ake amkati. Silicone yopanda organic nthawi zambiri imakhala ndi ma porosity ambiri, zomwe zimapangitsa kuti mamolekyu a mpweya afalikire kudzera m'ma micropores ake amkati. Komabe, chifukwa cha mphamvu yayikulu ya mamolekyu ndi ma pores ochepa, silicone yachilengedwe imakhala ndi kupuma kochepa. Kawirikawiri, kulowa kwa mpweya kwa silicone ndi koipa kuposa ma elastomer ambiri a thermoplastic (monga TPE), koma akadali otsika poyerekeza ndi nsalu zachikhalidwe.

2. Njira yoyesera mpweya wokwanira
(I) Muyezo woyesera mpweya wokwanira
Kuyesa mpweya wokwanira ndi njira yofunika kwambiri yowunikira mpweya wokwanira wa nsalu, ndipo ndikofunikira kwambiri pakupanga ndi kusankha zovala zamkati za silicone. Njira zoyesera mpweya wokwanira zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo njira yokulira, njira yoyendera ndi njira ya thanki yonyowa. Njirazi zimawunika mpweya wokwanira poyesa kuchuluka kapena kuchuluka kwa mpweya wodutsa mu nsalu nthawi iliyonse.
(II) Masitepe oyesera
Potengera GB/T 24218.15 mwachitsanzo, njira zenizeni zoyesera mpweya ndi izi:
Kusankha Zitsanzo: Sankhani zitsanzo 5 mwachisawawa ndikuzidula mu kukula kwa 100mm × 100mm.
Sinthani chitsanzo: Ikani chitsanzocho pamalo abwino, gwiritsani ntchito motsatira GB/T 6529, ndipo sinthani chinyezi kuti chikhale bwino.
Ikani chitsanzo: Ikani chitsanzocho pamutu woyesera ndikuchimangirira kuti mpweya usatuluke.
Sinthani kayendedwe ka mpweya: Yatsani pampu yotulutsa mpweya ndikukonza kayendedwe ka mpweya mpaka kusiyana kwa kuthamanga kuli 100Pa, 125Pa kapena 200Pa.
Werengani kuchuluka kwa mpweya wolowera: Kupanikizika kukakhazikika, werengani kuchuluka kwa mpweya wolowera mu malita/sikweya sentimita masekondi L/(cm)
2
⋅s).

(III) Zotsatira za mayeso
Malinga ndi zotsatira za mayeso, mpweya wolowa m'zinthu za silicone nthawi zambiri umakhala woipa. Mwachitsanzo, ma bra a silicone osawoneka bwino amakhala ndi mpweya wolowa m'malo chifukwa cha zinthu zawozawo. Kuvala kwa nthawi yayitali kungayambitse zizindikiro monga erythema ndi kuyabwa pakhungu.

III. Ndemanga za ogwiritsa ntchito ndi zomwe zachitikadi
(I) Ndemanga za ogwiritsa ntchito
Ogwiritsa ntchito ambiri anena kuti ngakhale zovala zamkati za silicone zili ndi ubwino winawake pakuwoneka bwino komanso kumasuka, vuto losalowa mpweya wabwino ndi lofala. Ogwiritsa ntchito ena anena kuti akavala zovala zamkati za silicone kwa nthawi yayitali, khungu limayamba kutuluka thukuta ndipo silingathe kutuluka pakapita nthawi, zomwe zimapangitsa kuti munthu asamve bwino.
(II) Zochitika zenizeni
Muzochitika zenizeni, mpweya woipa wa zovala zamkati za silicone umaonekera makamaka m'mbali zotsatirazi:
Kuvala kwa nthawi yayitali: Munthu akavala zovala zamkati za silicone kwa nthawi yayitali, khungu limakhala ndi thukuta ndipo silingathe kutuluka pakapita nthawi, zomwe zimapangitsa kuti khungu likhale lonyowa komanso loyabwa.
Kukhudzana ndi khungu: Zinthu zopangidwa ndi silicone zimalumikizana kwambiri ndi khungu, koma mpweya sulowa bwino, zomwe zimapangitsa kuti pakhale mavuto pakhungu mosavuta.
Zochitika pamasewera: Pamasewera kapena zochitika zotuluka thukuta, kusowa kwa mpweya wabwino wa zovala zamkati za silicone kumawonekera kwambiri.

4. Zinthu zomwe zimakhudza kupuma bwino
(I) Kapangidwe ka zinthu
Kupuma bwino kwa zinthu za silicone kumakhudzidwa kwambiri ndi kapangidwe kake ka mamolekyu ndi ma porosity. Silicone yopanda organic ili ndi ma porosity ambiri komanso mpweya wabwino; pomwe silicone yachilengedwe ili ndi ma pores ochepa komanso mpweya wochepa.
(II) Kukonza kapangidwe kake
Ngakhale kuti mpweya wabwino wa zinthu za silicone ndi wochepa, vutoli lingathe kuchepetsedwa pang'ono mwa kusintha kapangidwe kake. Mwachitsanzo, zovala zina zamkati za silicone zawonjezera mabowo opumira kapena zagwiritsa ntchito kapangidwe kake ka multilayer mu kapangidwe kake kuti ziwongolere mpweya wabwino. Komabe, zotsatira za njira izi zowongolera mpweya ndizochepa ndipo sizingathe kuthetsa vuto la mpweya wabwino kwathunthu.
(III) Zinthu zokhudzana ndi chilengedwe
Zinthu zachilengedwe monga kutentha ndi chinyezi zingakhudzenso momwe zovala zamkati za silicone zimapumira. Mu malo otentha kwambiri komanso chinyezi chambiri, kupuma kwa zovala zamkati za silicone kumachepa kwambiri, zomwe zimapangitsa kuti mavuto a pakhungu awonekere kwambiri.

5. Momwe mungasinthire mpweya wabwino wa zovala zamkati za silicone
(I) Sankhani zinthu zoyenera
Mukasankha zovala zamkati za silicone, mutha kuyang'ana kwambiri zinthu zopangidwa ndi silicone chifukwa zimakhala ndi mpweya wabwino. Kuphatikiza apo, zinthu zina zatsopano za silicone zakweza mpweya wabwino mwa kukonza kapangidwe ka mamolekyu, zomwe zingagwiritsidwenso ntchito ngati chizindikiro cha kusankha.
(II) Kukonza kapangidwe kake
Kwa opanga, mpweya wabwino wa zovala zamkati za silicone ukhoza kusinthidwa kudzera mu kusintha kwa kapangidwe kake kameneka:
Kuonjezera mabowo opumira mpweya: Kuyika mabowo opumira mpweya m'zovala zamkati za silicone kungathandize kwambiri kuti mpweya upume bwino.
Kapangidwe ka zigawo zambiri: Kugwiritsa ntchito kapangidwe ka zigawo zambiri komanso kugwiritsa ntchito zipangizo zomwe zimapuma bwino pakati pa gawo kungathandize kuti mpweya upume bwino.
Kukonza bwino momwe zovala zamkati zimagwirizanira: Kusintha bwino momwe zovala zamkati za silicone zimagwirizanira kuti zisagwirizane kwambiri pakhungu kungachepetse mavuto a pakhungu.
(III) Malangizo ogwiritsira ntchito
Kwa ogula, njira zotsatirazi zingagwiritsidwe ntchito kuchepetsa mavuto omwe amayamba chifukwa cha kupuma kosakwanira kwa zovala zamkati za silicone:
Lamulirani nthawi yovala: Pewani kuvala zovala zamkati za silicone kwa nthawi yayitali. Ndikofunikira kuti nthawi yovala isapitirire maola 6 nthawi iliyonse.
Sungani zoyera komanso zouma: Tsukani zovala zamkati za silicone nthawi zonse ndipo sungani zoyera komanso zouma kuti muchepetse kukula kwa mabakiteriya ndi mavuto a pakhungu.
Sankhani malo oyenera: Mukamachita masewera olimbitsa thupi kapena kutuluka thukuta kwambiri, yesetsani kupewa kugwiritsa ntchito zovala zamkati za silicone ndipo sankhani zovala zamkati zachikhalidwe zomwe zimapuma bwino.

VI. Mapeto
Popeza ndi zovala zapadera komanso kapangidwe kake, zovala zamkati za silicone zili ndi ubwino winawake pa mawonekedwe ake komanso chitonthozo, koma kupuma movutikira ndi vuto lomwe silinganyalanyazidwe. Kudzera mu mayeso opumira mpweya komanso ndemanga za ogwiritsa ntchito, zitha kuwoneka kuti zovala zamkati za silicone zili ndi zofooka zodziwikiratu pa kupuma, ndipo kuvala kwa nthawi yayitali kungayambitse mavuto a pakhungu mosavuta. Ngakhale vutoli lingathe kuchepetsedwa pang'ono kudzera mukusintha kapangidwe kake, vuto la kupuma movutikira silingatheke kwathunthu. Chifukwa chake, posankha zovala zamkati za silicone, ogula ayenera kuganizira zabwino ndi zoyipa zake mokwanira ndikupanga zisankho zoyenera kutengera zosowa zawo komanso momwe amagwiritsidwira ntchito. Nthawi yomweyo, opanga ayenera kupitiliza kukonza kapangidwe ndi zida za zovala zamkati za silicone kuti awonjezere kupuma komanso chitonthozo chake kuti zikwaniritse zosowa za ogula.
