Borosilicate galasindi mtundu wa galasi lomwe lili ndi boron trioxide yomwe imalola kuti pakhale coefficient yotsika kwambiri yakukula kwamafuta.Izi zikutanthauza kuti sichidzasweka pansi pa kusintha kwa kutentha kwambiri monga galasi lokhazikika.Kukhazikika kwake kwapangitsa kuti ikhale galasi yosankha malo odyera apamwamba, ma labotale ndi malo opangira vinyo.
Chimene anthu ambiri sadziwa n’chakuti si magalasi onse amapangidwa mofanana.
Magalasi a Borosilicate amapangidwa ndi pafupifupi 15% boron trioxide, yomwe ndi chinthu chamatsenga chomwe chimasintha khalidwe la galasi ndikupangitsa kuti zisawonongeke chifukwa cha kutentha.Izi zimathandiza kuti galasi lisagwirizane ndi kusintha kwakukulu kwa kutentha ndipo limayesedwa ndi "Coefficient of Thermal Expansion," mlingo umene galasi limakula likakhala ndi kutentha.Chifukwa cha izi, galasi la borosilicate limatha kuyenda molunjika kuchokera mufiriji kupita ku choyikapo ng'anjo popanda kusweka.Kwa inu, izi zikutanthauza kuti mutha kuthira madzi otentha otentha mugalasi la borosilicate ngati mukufuna kunena, tiyi wotsetsereka kapena khofi, osadandaula za kuswa kapena kusweka galasi.
KODI KUSIYANA KODI PAKATI PA GLASS YA BOROSILICATE NDI SODA-LIME GLASS?
Makampani ambiri amasankha kugwiritsa ntchito galasi la soda-laimu popanga magalasi awo chifukwa ndi otsika mtengo komanso amapezeka mosavuta.Amawerengera 90% ya magalasi opangidwa padziko lonse lapansi ndipo amagwiritsidwa ntchito ngati mipando, miphika, magalasi akumwa ndi mazenera.Soda laimu galasi atengeke kunjenjemera ndipo salola kusintha kwambiri kutentha.Mankhwala ake ndi 69% silika (silicone dioxide), 15% soda (sodium oxide) ndi 9% laimu (calcium oxide).Apa ndipamene dzina la galasi la soda-laimu limachokera.Ndi cholimba pa kutentha wamba.
BOROSILICATE GLASS NDI WAPAMBALI
Coefficient ya galasi la soda-laimu ndikuposa kawiri kuposa galasi la borosilicate, kutanthauza kuti imafutukuka kuwirikiza kawiri mofulumira ikakumana ndi kutentha ndipo idzasweka mofulumira kwambiri.Magalasi a Borosilicate ali ndi zambirikuchuluka kwakukulu kwa silicon dioxidepoyerekeza ndi galasi la soda laimu wokhazikika (80% vs. 69%), zomwe zimapangitsa kuti zikhale zosavuta kuthyoka.
Pankhani ya kutentha, kutentha kwakukulu kwa kutentha (kusiyana kwa kutentha komwe kungathe kupirira) kwa galasi la borosilicate ndi 170 ° C, pafupifupi 340 ° Fahrenheit.Ichi ndichifukwa chake mutha kutenga galasi la borosilicate (ndi zina zophikidwa monga Pyrex-zambiri pa izi pansipa) kuchokera mu uvuni ndikuyendetsa madzi ozizira pamwamba pake popanda kuphwanya galasi.
* Zosangalatsa zowona, galasi la borosilicate ndi losagwirizana ndi mankhwala, kotero kuti limagwiritsidwa ntchitosungani zinyalala za nyukiliya.Boron yomwe ili mugalasi imapangitsa kuti isasungunuke kwambiri, kulepheretsa zinthu zilizonse zosafunikira kuti zisalowe mugalasi, kapena mwanjira ina.Ponena za magwiridwe antchito, galasi la borosilicate ndilabwino kwambiri kuposa magalasi wamba.
KODI PYREX NDI YOMWEYO NDI BOROSILICATE GLASS?
Ngati muli ndi khitchini, mwina munamvapo za dzina la 'Pyrex' kamodzi.Komabe, galasi la borosilicate silifanana ndi Pyrex.Pamene Pyrex idagundika koyamba pamsika mu 1915, idapangidwa poyambira magalasi a borosilicate.Adapangidwa kumapeto kwa zaka za m'ma 1800 ndi wopanga magalasi waku Germany Otto Schott, adayambitsa dziko lapansi ku magalasi a borosilicate mu 1893 pansi pa dzina la Duran.Mu 1915, Corning Glass Works inabweretsa ku msika waku US pansi pa dzina la Pyrex.Kuyambira pamenepo, galasi la borosilicate ndi Pyrex akhala akugwiritsidwa ntchito mosinthana muchilankhulo cholankhula Chingerezi.Chifukwa Pyrex glass bakeware poyambilira idapangidwa ndi galasi la borosilicate, idatha kupirira kutentha kwambiri ndikupangitsa kuti ikhale khitchini yabwino kwambiri komanso ng'anjo yamoto, zomwe zimathandizira kutchuka kwake kwazaka zambiri.
Masiku ano, si Pyrex yonse yomwe imapangidwa ndi galasi la borosilicate.Zaka zingapo zapitazo, Corninganasintha zinthu m'zinthu zawokuchokera ku galasi la borosilicate kupita ku galasi la soda-laimu, chifukwa linali lokwera mtengo.Chifukwa chake sitingakhale otsimikiza kuti borosilicate ndi chiyani chomwe sichili pamzere wa Pyrex's bakeware.
KODI GALASI YA BOROSILICATE AMAGWIRITSA NTCHITO CHIYANI?
Chifukwa cha kulimba kwake komanso kukana kusintha kwa mankhwala, galasi la borosilicate lakhala likugwiritsidwa ntchito m'ma laboratories a chemistry ndi mafakitale, komanso kukhitchini ndi magalasi a vinyo apamwamba.Chifukwa cha khalidwe lake lapamwamba, nthawi zambiri imakhala yamtengo wapatali kuposa galasi la soda.
KODI NDISINTHIRE KUBOTOLO LA GALASI LA BOROSILICATE?KODI NDI NDALAMA ZANGA?
Kusintha kwakukulu kungapangidwe ndi kusintha kwakung'ono kwa zizolowezi zathu za tsiku ndi tsiku.Munthawi ino, kugula mabotolo amadzi apulasitiki otayidwa ndikopusa chabe poganizira njira zina zonse zomwe zilipo.Ngati mukuganiza zogula botolo lamadzi logwiritsidwanso ntchito, ndiye gawo loyamba lothandizira kusintha moyo wanu.Ndikosavuta kupeza chinthu chotsika mtengo komanso chogwira ntchito, koma ndiye malingaliro olakwika ngati mukufuna kukonza thanzi lanu ndikupanga kusintha kwa moyo wanu.Malingaliro athu ndiabwino kuposa kuchuluka kwake, ndipo kugula zinthu zokhalitsa kumawononga ndalama zambiri.Nawa maubwino ena oyika ndalama mu botolo lagalasi la borosilicate la premium reusable.
Ndibwino kwa inu.Popeza galasi la borosilicate limatsutsa mankhwala ndi kuwonongeka kwa asidi, simuyenera kudandaula ndi zinthu zomwe zimalowa m'madzi anu.Nthawi zonse ndi zabwino kumwa.Mukhoza kuziyika mu chotsukira mbale, kuziyika mu microwave, kuzigwiritsira ntchito kusunga zakumwa zotentha kapena kuzisiya padzuwa.Simudzayenera kudzidetsa nkhawa ndi kutentha kwa botolo ndikutulutsa poizoni wowopsa mumadzi omwe mukumwa, zomwe zimapezeka kwambiri m'mabotolo amadzi apulasitiki kapena zitsulo zosapanga dzimbiri zotsika mtengo.
Ndi bwino kwa chilengedwe.Mabotolo amadzi apulasitiki ndi owopsa kwa chilengedwe.Amapangidwa kuchokera ku petroleum, ndipo pafupifupi nthawi zonse amatha kutayira, nyanja kapena nyanja.Ndi 9% yokha ya pulasitiki yonse yomwe imasinthidwanso.Ngakhale zili choncho, nthawi zambiri kuphwanya ndikugwiritsanso ntchito mapulasitiki kumasiya mpweya wolemera.Popeza galasi la borosilicate limapangidwa kuchokera kuzinthu zambiri mwachibadwa zomwe zimapezeka mosavuta kuposa mafuta, zotsatira za chilengedwe zimakhalanso zazing'ono.Ngati itagwiridwa mosamala, galasi la borosilicate lidzakhala moyo wonse.
Zimapangitsa kuti zinthu zikhale bwino.Kodi munayamba mwamwako kuchokera ku pulasitiki kapena mabotolo a zitsulo zosapanga dzimbiri ndi kulawa pulasitiki kapena zitsulo zomwe mukumweramo?Izi zimachitika chifukwa imalowa m'madzi anu chifukwa cha kusungunuka kwa pulasitiki ndi chitsulo.Izi ndizowononga thanzi lanu komanso zosasangalatsa.Mukamagwiritsa ntchito galasi la borosilicate madzi mkati mwake amakhalabe oyera, ndipo chifukwa galasi la borosilicate limakhala losungunuka pang'ono, limapangitsa kuti zakumwa zanu zisawonongeke.
GALASI SI GALASI WABWINO
Ngakhale kuti mitundu yosiyanasiyana ingawoneke yofanana, si yofanana.Galasi ya Borosilicate ndiyokwera kwambiri kuchokera ku galasi lachikhalidwe, ndipo kusiyana kumeneku kungapangitse kwambiri thanzi lanu komanso chilengedwe mukaphatikizana ndi nthawi.
