Kampani yathu - Jiangsu Fuhao Yihao Plastic Viwanda Co., Ltd., ili ku Yancheng, Jiangsu. Kampani yathu ili ndi zida zonse zopangira ndi kupanga zamafakitale ofananira, ndipo ketulo yayikulu kwambiri ya isobaric ku China ili mufakitoli yathu.
Chida ichi chimakhudzanso malo otchuka apadziko lonse lapansi a PTFE okhala ndi mapaipi opangira mapaipi - okhala ndi mapaipi a isostatic pressure ketulo. Kupondereza kwa Isostatic ndi njira yowonjezerera zadothi za granulated ku nkhungu, yomwe nthawi zambiri imapangidwa ndi pulasitiki kapena mphira wokhala ndi kuchuluka kwamphamvu. Mu makina osindikizira a isostatic, kukakamiza kofanana kwa makumi mpaka mazana a megapascals kumayikidwa pa nkhungu kuti igwirizane ndi kupanga pulasitiki ya granulated mu nkhungu. Pali njira ziwiri zopangira kukakamiza kwa isostatic: kuzizira kwa isostatic ndi kutentha kwa isostatic. Kukanikiza kozizira kwa isostatic kumagawidwanso m'njira zonyowa komanso zowuma. Njira yozizira ya isostatic yomwe imagwiritsidwa ntchito ku China imakhala yonyowa kwambiri. Monga kukanikiza kowuma, granulation imachitikanso musanakanikize isostatic. Kusiyana kwake ndikuti tinthu tating'onoting'ono ta granulation timene timagwiritsidwa ntchito pokanikizira kotentha kwa isostatic.

Mfundo yogwira ntchito ya kukakamiza kwa isostatic ndi lamulo la Pascal: "Kupanikizika kwa sing'anga (zamadzimadzi kapena gasi) mu chidebe chotsekedwa kungathe kufalitsidwa mofanana kumbali zonse." Isostatic kukanikiza luso ali ndi mbiri ya zaka zoposa 70 ndipo poyamba ankagwiritsa ntchito zitsulo ufa kupanga ufa; M'zaka 20 zapitazi, isostatic kukanikiza umisiri wakhala ankagwiritsa ntchito mu ceramic kuponyera, mphamvu atomiki, kupanga zida, mapulasitiki, kopitilira muyeso-mkulu kuthamanga chakudya kulera, graphite, ziwiya zadothi, maginito okhazikika, mkulu-pressure electromagnetic porcelain mabotolo, biopharmaceutical kukonzekera, chakudya. kusungidwa, zida zogwirira ntchito kwambiri, mafakitale ankhondo, zida zamankhwala, mankhwala ndi zina.
1.Cold isostatic kukanikiza
Cold Isostatic Pressing (CIP) ndi ukadaulo womwe nthawi zambiri umagwiritsa ntchito mphira kapena pulasitiki ngati zida zomangira nkhungu kutentha kwa firiji, ndi madzi ngati choponderezera, chomwe chimagwiritsidwa ntchito popanga zinthu zaufa, kupereka billet kwa sintering, calcination, kapena kutentha. isostatic kukanikiza njira. Kuthamanga kwanthawi zonse ndi 100-630MPa.
2.Kutentha kwa isostatic
Tekinoloje yotentha ya isostatic imagwira ntchito pa kutentha kwa 80-120 ℃. Palinso zakumwa zapadera kapena mpweya womwe umagwiritsidwa ntchito kusamutsa kuthamanga kwa kutentha kwa 250-450 ℃, ndi kukakamiza kogwira ntchito mozungulira 300MPa. Makamaka ntchito graphite, polyamide mphira zipangizo, etc. kuti sangathe kupangidwa ndi zipangizo ufa firiji. Kukwaniritsa billet olimba pa kutentha okwera.
3.Hot isostatic kukanikiza
Hot isostatic pressing (HIP) ndi ukadaulo waukadaulo womwe umalola kuti zinthu zitheke kukakamizidwa ndi isostatic panthawi imodzi ya kutentha kwambiri komanso kuthamanga kwambiri. Sichimagwiritsidwa ntchito kokha kulimbitsa ufa, komanso kugwirizanitsa zomangira zogwirira ntchito, kuchotsa zolakwika zoponyera, ndi kupanga ziwalo zooneka bwino muzochitika zazitsulo za ufa. Mu kukanikiza kotentha kwa isostatic, mipweya ya inert monga argon ndi ammonia nthawi zambiri imagwiritsidwa ntchito ngati media media, ndipo zotengerazo nthawi zambiri zimakhala zitsulo kapena galasi. Kutentha kwa ntchito nthawi zambiri kumakhala pakati pa 1000 ~ 2200 ℃, ndipo kuthamanga kwa ntchito kumakhala pakati pa 100 ~ 200MPa.
Ubwino wa Isostatic Pressing Technology
Monga njira yopangira, ukadaulo wopondereza wa isostatic uli ndi zotsatirazi poyerekeza ndi njira wamba zopangira:
1. Kachulukidwe wazinthu zopangidwa ndi kukanikiza kwa isostatic nthawi zambiri ndi 5 ~ 15 kuposa momwe zimapangidwira komanso zapawiri. Kachulukidwe wachibale wa mankhwala otentha isostatic kukanikiza akhoza kufika 99.8% ~ 99.09%.
2. Kuchulukana kwa compact ndi yunifolomu komanso kusinthasintha. Pakuumba, kaya ndi kukakamiza kwa unidirectional kapena bidirectional, kugawa kosagwirizana kwa compact density kudzachitika. Kusintha kwa kachulukidweku kumatha kufika pa 10% mukakakamiza zinthu zowoneka bwino. Izi zimachitika chifukwa cha kusagwirizana pakati pa ufa ndi nkhungu yachitsulo. Kupanikizika komwe kumaperekedwa ndi isostatic pressure fluid sing'anga ndikofanana mbali zonse. Kuponderezedwa kwa phukusi ndi ufa nthawi zambiri kumakhala kosasinthasintha, ndipo palibe kusuntha pakati pa ufa ndi phukusi. Kukaniza kukaniza pakati pawo kumakhala kochepa, ndipo kupanikizika kumachepa pang'ono. Kachulukidwe kameneka kamakhala pansi pa 1%. Choncho, zikhoza kuganiziridwa kuti kachulukidwe ka billet ndi yunifolomu.
3. Chifukwa cha kachulukidwe ka yunifolomu, kutalika kwa chiŵerengero cha m'mimba mwake sikuli malire, zomwe zimapindulitsa kupanga zinthu zoonda komanso zazitali monga ndodo ndi machubu.
4. Njira yopondereza ya isostatic nthawi zambiri simafuna kuwonjezera mafuta ku ufa, zomwe zimachepetsa kuipitsidwa kwa mankhwala ndi kuphweka kupanga.
5. Zogulitsa zopangidwa ndi kukanikiza kwa isostatic zimakhala ndi magwiridwe antchito abwino kwambiri, kadulidwe kakang'ono kakupanga, komanso kugwiritsa ntchito mosiyanasiyana. Zoyipa za njira yosindikizira ya isostatic ndizotsika kwambiri komanso zida zodula.
Pakali pano, kampani yathu wakhazikitsa mgwirizano malonda ndi makasitomala ambiri kunyumba ndi kunja, ndipo wagwiritsa ntchito zipangizo kupanga zosiyanasiyana PTFE alimbane mankhwala mapaipi. Zopangira mapaipi amkati opangidwa ndi zida izi zimakhala ndi mawonekedwe abwino kwambiri, kukana kwapakatikati, ndipo kulumikizana kwamkati kumalumikizidwa mwamphamvu popanda mipata, mkati mwake mosalala komanso kosalala. Kampani yathu imalandila makasitomala mwachikondi ndi zomwe zimafunikira pakupangira kuti azigwirizana nafe kuti tipindule komanso kuti tipambane!
