Chophimba cha Silicone cha Chitetezo cha Mafoni ndi Kugwira

2026-10-03

Nthawi zonse mukakweza mphika wotentha, zala zanu mwachibadwa zimafunafuna kugwira, osati kungogwira, koma kuwongolera, kuyimitsa, kusintha popanda kutsetsereka. Chidaliro chogawanika chachiwiri chimenecho? Zimayamba kale chivundikirocho chisanakweze. Zimayamba ndi mawonekedwe akuthupi pakati pa manja ndi zophikira. Ndipo m'makhitchini zikwizikwi ku Europe, North America, ndi Southeast Asia, mawonekedwewa akuchulukirachulukira chivundikiro cha silicone-osati monga lingaliro lina, koma monga cholinga chopangidwa.

Tawona kusinthaku kukuchitika pazaka 12 zakukula kwa chivindikiro: zomangira za silicone zoyambira zinali zofewa, zokhuthala, komanso zokonda kukanikizana pansi pa njinga yamoto yobwerezabwereza. Ogwiritsa adanenanso kuti kutha, kukweza m'mphepete, kusungika kwa zisindikizo mosagwirizana. Kenako panabwera zophimba za silikoni zomangika molondola—zoonda (0.8–1.2 mm), m’mphepete mwa nyanja A65–A70 zokongoletsedwa, zolumikizidwa ndi laser m’mphepete mwa galasi. Ndipamene grip inasiya kukhala yokongoletsa ndikukhala zomangamanga zogwira ntchito.

A zoona chivundikiro cha silicone imachita zinthu zitatu nthawi imodzi: imachepetsa kugwedezeka panthawi yogwedezeka kapena kugwedezeka, imatenga mphamvu zazing'ono pamene zivindikiro zaikidwa kapena kuikidwa pansi, ndipo imafutukuka * yokwanira * pa kutentha kuti ikhalebe ndi mphamvu ya radial motsutsana ndi mkombero - palibe mpweya wa gasket, palibe mpweya wotuluka pa 120 ° C. Tidatsimikizira izi ndi mayeso a 5,200-cycle thermal shock (-20 ° C mpaka 180 ° C, kusintha kwa masekondi 90) pa SK-series lids. Zopangira magalasi a silicone okha zidadutsa popanda delamination kapena kutayika. mphira wamba analephera ndi mkombero 843. TPE zosiyanasiyana anasonyeza 40% psinjika kukhazikitsidwa pambuyo 1,200 m'zinthu. Silicone idakhazikika - chifukwa msana wake wa polima umakana kutsetsereka komwe ena amapumula.

Koma si zophimba zonse za silicone zimagwira ntchito mofanana. Zinthu zitatu zimalekanitsa mapangidwe otsimikiziridwa ndi munda ndi zodzaza mashelufu:

Kugwirizana kwa umphumphu: Mawonekedwewa samamatira - amachiritsidwa limodzi. Silicone imalowa m'magalasi ozungulira (Ra ≤ 0.4 µm) isanawonongeke. Palibe wosanjikiza zomatira zikutanthauza kuti palibe ndege yolephera. Kukana kwa peel kumapitilira 12 N/mm-kuyezedwa pogwiritsa ntchito ma protocol a ISO 8510-2 pagawo lotentha la borosilicate.

Kutentha kwa coefficient: Galasi amakula ~3.3 × 10⁻⁶ /°C; silikoni yoyera kwambiri imakula ~250 × 10⁻⁶ /°C. Mosayang'aniridwa, kusagwirizanaku kumayambitsa kupindika m'mphepete kapena kusweka kwa bond. Zivundikiro zathu za CA13 zimagwiritsa ntchito njira yochizira gradient: zigawo zakunja za silikoni zimalumikizana mwamphamvu kwambiri, zigawo zamkati zimasunga kusinthasintha-kukulitsa kwaukonde komwe kumayendetsedwa ndi 12.7 × 10⁻⁶ /°C. Zotsatira: zero zowoneka bwino pa 200 ° C.

Gwirani geometry: Zingwe zosalala za silicone zimaterera. Timagwiritsa ntchito nthiti zozungulira - 0.3 mm wamtali, 0.5 mm phula, zopindika 18 ° mkati. Amapondereza pa kukhudzana, kukulitsa kukangana pamwamba ndi 3.2 × motsutsana ndi silikoni yosalala (kuyesa kwa ASTM D1894). Ndipo amatengera kukhazikika kutali ndi malo ogwirira - chofunikira kwambiri pakugwira ntchito kwamanja.

Ena angatsutse kuti silikoni imawonjezera mtengo popanda phindu lachitetezo. Koma ogwirizana athu a OEM ku Germany ndi Canada adatsata 17% zocheperako zomwe zidagwa m'makhitchini amalonda atasinthira ku zivundikiro za silicone-composite. Chifukwa chiyani? Osati chifukwa silicone ndi "yomata" -koma chifukwa imachotsa malingaliro olakwika achitetezo omwe magalasi osalala amapanga. Mukumva * chinkhoswe. Chala chanu chachikulu chimalembetsa kukana torque isanamangidwe. Kuyankha kwamphamvu kumeneku kumadula nthawi yochitapo ndi masekondi 0.37 pafupipafupi - zokwanira kuteteza kutentha.

Mtengo ndi wofunika - koma musaganize molakwika, ndipo mumalipira kawiri. Zophimba za silicone zolowera zimagwiritsa ntchito zodzaza zobwezerezedwanso, durometer yosagwirizana, ndi zoyambira zosungunulira. Amawononga 22% pang'ono kutsogolo koma amalephera 3.8 × mwachangu m'malo achinyezi (pakukalamba kofulumira pa IEC 60068-2-30). Mzere wathu wa SGC umagwiritsa ntchito silikoni ya namwali ya VMQ, machiritso opangidwa ndi platinamu, ndi galasi lopaka madzi a m'magazi—$0.83 apamwamba pa unit iliyonse, komabe amapereka moyo wautali wautali wa 4.1×. Kwa ogulitsa omwe amasunga mayunitsi 20,000 pachaka, ndiye $16,600 yosungidwa m'malo osungira okha.

Kuyika sikufuna zida - koma kumafuna chidwi pazinthu ziwiri. Choyamba: yeretsani m'mphepete mwa galasi ndi mowa wa isopropyl * musanayambe * kugwirizana. Mafuta otsalira amachepetsa kumamatira mpaka 60%. Chachiwiri: gwiritsani ntchito kuthamanga kwa yunifolomu kwa masekondi a 90 pambuyo poika. Timapereka ma jig osavuta - njanji ziwiri za aluminiyamu zodzigudubuza zodzaza masika - zomwe zimatsimikizira kulumikizana kwa 0.15 MPa mozungulira mozungulira. Dumphani izi, ndipo muwona kubweza kwanuko mkati mwa miyezi itatu.

EUR-ASIA COOKWARE CO., LTD sipanga ma foni kapena zida zamagetsi. Timayika makina opangira zivundikiro - makina a lid okha - m'malo omwe kutentha, kutopa kwamakina, ndi ma ergonomics amadutsa tsiku lililonse. Aliyense chivundikiro cha silicone timatumiza timanyamula traceability kubwerera ku silikoni yaiwisi yaiwisi, kuchiritsa chipika uvuni, ndi lipoti kuyendera kuwala. Chifukwa kugwira sikukhudza kapangidwe. Ndi za kudalira-kuyezedwa mu millimeters, madigiri, ndi milliseconds.

Yang'anani m'tsogolo: zophimba za silicone za m'badwo wotsatira sizingogwira - zidzawonetsa. Ma trace ophatikizidwa (oyesedwa ku IP67) azindikira kuyika kwa chivundikiro ndikutumiza malo ophikira anzeru. Osati sci-fi. Ma prototypes adatumizidwa ku ma OEM atatu a EU kotala lapitali. Tsogolo lachitetezo cha khitchini silikhala machenjezo okulirapo. Ndikopanda phokoso, kotsimikizika, kukhudzana ndi makina amunthu mosasunthika - kopangidwa ndendende chivundikiro cha silicone pa nthawi.

Zam'mbuyo. Kenako.
