1 2 Galasi Mtsuko Wokhala Ndi Chivundikiro Chopanda Mpweya Chosungira Chakudya Chatsopano 

Kusunga zinthu zowuma, zinthu zambiri zamkati, kapena zopangira kunyumba zimafuna zambiri osati zowonekera komanso zosavuta - zimafuna kudalirika. A 1 2 galoni galasi botolo ndi chivindikiro mpweya si kukweza kwapamwamba. Ndilo maziko oletsa kulowerera kwa chinyezi, makutidwe ndi okosijeni, kupezeka kwa tizilombo, komanso kuwonongeka kwa kukoma kwa milungu kapena miyezi. Tayesa mitsuko yambiri "yopanda mpweya" m'malo akukhitchini enieni - maphikidwe ogulitsa, malo opangira chakudya, ndi zakudya zapanyumba m'maiko asanu ndi limodzi - ndipo tidapeza kuti ambiri amalephera kusindikiza, osati galasi.

Galasi ya Borosilicate Siyosasankha-Siyokambirana

Standard koloko laimu galasi mitsuko kung'ambika pansi matenthedwe mantha: otentha kupanikizana anatsanulira mu chipinda kutentha mtsuko, kapena ozizira mtsuko anaika pa ofunda countertop. Ichi ndichifukwa chake mtsuko uliwonse wagalasi wokhala ndi galoni 1 2 wokhala ndi chivindikiro chopanda mpweya timalimbikitsa kugwiritsa ntchito galasi la borosilicate-monga Pyrex® koma lopangidwira kukwera njinga mobwerezabwereza. Coefficient yake yakukulitsa kutentha ndi pansi pa 3.3 × 10⁻⁶/K. Nambala imeneyo ndiyofunika. M'machitidwe, zikutanthauza kuti mtsuko umapulumuka ndikuwotchera m'madzi otentha, kusinthira mufiriji kupita ku kauntala, ndi makina otsuka mbale popanda ma microfractures.

Tidayeza kukhulupirika kwa chisindikizo pamitundu 14 pogwiritsa ntchito kuyezetsa kowola kwamphamvu (ASTM F2096). Atatu okha ndi omwe adagwira vacuum kupitilira maola 72. Onse atatu anali ndi khalidwe limodzi: matupi a borosilicate ophatikizidwa ndi zomangira za silikoni zapawiri-gasket-osati mapangidwe a mphete imodzi. Kusiyana kwake? Ma gaskets apawiri amadzipanikiza paokha—imodzi imatseka m’mphepete mwake, ina imatsekera tsinde la chivindikiro—kuchotsa mipata yobwera chifukwa cha torque polimbitsa dzanja.

Zosataya mpweya ≠ Umboni Wotulutsa-Apa Ndiko Mitsuko Yambiri Imalephera

"Airtight" ndikutsatsa kwachidule. Kuchita zenizeni padziko lapansi kumadalira mitundu itatu yamakina: gasket durometer, kulolerana kwa ulusi wa lid-to-mtsuko, ndi kusinthasintha kwa torque. Silicone yofewa (M'mphepete mwa nyanja A 40-50) imapunduka mosavuta pomangana mosagwirizana; mphira wolimba (Shore A 70+) umakana kukanikiza ndikutuluka pa torque yotsika. Malo okoma? Mphepete mwa nyanja A 55-60, yomangidwa pagalasi yokhala ndi silane yomatira -osati madontho omatira kapena kuthirira kotentha.

Kulekerera kwa ulusi sikuwoneka koma kofunikira. Tinagawa mitsuko 12 ndikuyesa kupotoza kwa phula ndi optical profilometry. Ma Model okhala ndi ± 0.08 mm kulolerana adawukhira 3 × mwachangu kuposa omwe ali ndi ± 0.02 mm-ngakhale ndi ma gaskets ofanana. Kulekerera kolimba kumafuna zisankho zomangika bwino komanso kuwongolera ulusi pambuyo pakutentha. Ichi ndichifukwa chake mitsuko yopangidwa mochuluka nthawi zambiri imakhala "yogwedezeka" ikaphwanyidwa: ulusi wawo suli wokhazikika.

Ena angatsutse kuti zivundikiro zazitsulo zosapanga dzimbiri zimathetsa zimenezi. Iwo samatero. Chitsulo chimakula mofulumira kuposa galasi. Pa 60 ° C, mphete yachitsulo imamasula mphamvu yake ndi 0.012 mm pa inchi imodzi ya m'mimba mwake-yokwanira kuti iwononge kupitiriza kwa chisindikizo. Zivundikiro zagalasi zokhala ndi magalasi kapena zomangika za silikoni zimasunga kukhazikika kwa mawonekedwe kudutsa -20°C mpaka +150°C.

Zomwe Zimagwira Ntchito Pantchito Yatsiku ndi Tsiku - Osati Mayeso a Labu Okha

Tinatsata kugwiritsidwa ntchito m'mabanja 87 kwa masiku 90. Mtsuko wagalasi wowoneka bwino kwambiri wa galoni 1 2 wokhala ndi chivindikiro chosatulutsa mpweya umagawana makhalidwe anayi otsimikiziridwa:

Chitsanzo chimodzi chinadziwika: kasinthidwe ka CA09. Mawonekedwe ake a octagonal amathandizira kugwira ntchito podzaza, makina ake osindikizira awiri adadutsa maola 100, ndipo makulidwe ake a gasket 1.5 mm amalepheretsa kutuluka pansi pa 15 kg ya kulemera kwake. Ogwiritsa adanenanso kuti zero lid warping pambuyo pa miyezi isanu ndi umodzi yogwiritsa ntchito sabata iliyonse.

Chifukwa Chake Sayansi Yazinthu Imapambana Chikoka Chokongola

Kumveketsa bwino n’kofunika—koma kokha ngati kukhalitsa. Zivundikiro zagalasi wamba mtambo pambuyo pa makina otsuka mbale 12 chifukwa cha kutsekemera kwa alkaline kuchokera ku zotsukira. Borosilicate amatsutsa izi. Koma kumveketsa kokha sikulepheretsa kuwonongeka. Tinayesa mpunga, ufa, nyemba za khofi, ndi mphodza zouma zosungidwa m’mikhalidwe yowunikira yofanana. Pambuyo pa masiku 45, zitsanzo m'mitsuko yopanda borosilicate zimasonyeza 22% kutsekemera kwa chinyezi-kuyesedwa gravimetrically-chifukwa ma micro-pores mu galasi lotsika amalola kufalikira kwa nthunzi.

EUR-ASIA COOKWARE CO.,LTD imapanga izi m'magulu onse. Malo awo ophatikizika ophatikizika amawongolera nthawi yoziziritsa, machulukidwe olowera, ndi chinyezi chomangira cha silicone - zonse zimayikidwa pagawo lililonse. Umu ndi momwe amatsimikizira kukhulupirika kwa chisindikizo kudutsa kusinthasintha kwa chinyezi ku Europe, kutentha kwambiri kwa North America, komanso mafunde akumwera chakum'mawa kwa Asia. Simufunika zolemba zotsimikizira kuti mutsimikizire mtundu wake. Mufunika mtsuko womwe umapangitsa kuti oats wanu azisungunuka m'miyezi itatu.

Chigamulo Chomaliza: Sankhani kwa Fizikisi, Osati Kupaka

A 1 2 galoni galasi botolo ndi chivindikiro mpweya Imapeza malo ake posungirako chakudya chokhazikika pokhapokha sayansi yakuthupi, kapangidwe ka makina, ndi kupanga zinthu zikugwirizana. Dumphani mitsuko yomwe imatsindika za "chithumwa chowomberedwa ndi manja" kapena "kalembedwe kakale." Ikani patsogolo kamangidwe ka borosilicate, kusindikiza kwapawiri-gasket, ± 0.02 mm kulolerana kwa ulusi, ndikutsimikizira kukhazikika kwamafuta. Pitani ku glass-lid.com kuti muonenso malipoti oyesa, zojambula zowoneka bwino, ndi ziphaso zodziwika ndi gulu—zolemba zowonekera, osati zithunzi zazinthu zokha. Chifukwa chatsopano sichisungidwa mwadala. Zimasungidwa mwatsatanetsatane.
