Malinga ndi cholinga chachikulu chopangira ma fomula a rabala, ma fomula amatha kugawidwa m'mapangidwe oyambira, machitidwe ogwirira ntchito, ndi njira zogwirira ntchito.
1, Chilinganizo choyambirira
Basic formula, yomwe imadziwikanso kuti standard formula, nthawi zambiri imapangidwa ndi cholinga chozindikiritsa mphira wosaphika ndi zowonjezera.Pamene mtundu watsopano wa mphira ndi wothandizira wowonjezera ukuwonekera, ntchito yake yoyambira yokonzekera komanso mawonekedwe ake amayesedwa.Mfundo ya mapangidwe ake ndi kugwiritsa ntchito chikhalidwe ndi tingachipeze powerenga kusakaniza kufanana poyerekezera;Njirayi iyenera kukhala yophweka momwe zingathere ndi kubereka bwino.
Njira yoyambira imaphatikizanso zinthu zofunika kwambiri, ndipo mphira wopangidwa ndi zida zoyambira izi zitha kuwonetsa zonse zomwe zimachitika pakupanga mphira komanso mawonekedwe akuthupi komanso amakina a rabala wovunda.Tinganene kuti zigawo zikuluzikulu zimenezi ndi zofunika kwambiri.Pamaziko a chilinganizo choyambirira, sinthani pang'onopang'ono, sinthani, ndikusintha kuti mupeze fomula yokhala ndi zofunikira zina za magwiridwe antchito.Njira zoyambira zamadipatimenti zosiyanasiyana nthawi zambiri zimakhala zosiyana, koma zomatira zomwezo zimakhala zofanana.
Njira zoyambira zopangira mphira wodzilimbitsa nokha monga mphira wachilengedwe (NR), mphira wa isoprene (IR), ndi mphira wa chloroprene (CR) amatha kupangidwa ndi mphira wangwiro popanda zopangira zowonjezera (zothandizira), pomwe mphira wopanda mphira wodzilimbitsa. (monga mphira wa butadiene styrene, rabara ya ethylene propylene, etc.), katundu wawo wakuthupi ndi wamakina ndi otsika komanso osatheka, kotero kuti zowonjezera zowonjezera (zothandizira) ziyenera kuwonjezeredwa.
Chitsanzo choyimilira kwambiri pakali pano ndi njira yoyambira yamitundu yosiyanasiyana ya rabala yomwe ikugwiritsidwa ntchito pogwiritsa ntchito ASTTM (American Society for Testing and Materials) monga muyezo.
Njira yodziwika bwino yotchulidwa ndi ASTM ndi njira yoyambira yopangidwa ndi mafakitale opanga mphira ndizofunika kwambiri.Ndikwabwino kupanga chilinganizo choyambira kutengera momwe chipangizocho chilili komanso zomwe zidasonkhanitsidwa pagululo.Chidwi chiyeneranso kuperekedwa pakuwunika ubwino ndi kuipa kwa mafomu omwe amagwiritsidwa ntchito popanga zinthu zofananira pano, ndikuganiziranso kagwiritsidwe ntchito ka umisiri watsopano popanga zinthu zatsopano ndi kukonza ma formula.
2. Magwiridwe kachitidwe
Performance formula, yomwe imadziwikanso kuti technical formula.Fomula yopangidwa kuti ikwaniritse zofunikira zina, ndi cholinga chokwaniritsa magwiridwe antchito azinthu ndi kukonza, ndikuwongolera zina.
Fomula yogwirira ntchito imatha kuganizira mozama kuphatikiza kwa zinthu zosiyanasiyana pamaziko a chilinganizo choyambira, kuti zikwaniritse zofunikira pakugwiritsa ntchito zinthu.Njira yoyesera yomwe nthawi zambiri imagwiritsidwa ntchito popanga zinthu ndi njira yochitira, yomwe imagwiritsidwa ntchito kwambiri ndi opanga ma fomula.
3, Chilinganizo chothandiza
Njira yothandiza, yomwe imadziwikanso kuti formula yopangira, ndi njira yopangira chinthu china chake.
Mafomu othandiza ayenera kuganizira mozama zinthu monga kagwiritsidwe ntchito, kagwiridwe ntchito, mtengo wake, ndi momwe zida ziliri.Njira yomwe yasankhidwa iyenera kukhala yogwirizana ndi momwe zinthu zimapangidwira m'mafakitale, kuti zitheke bwino pakati pa magwiridwe antchito, mtengo, ndi kupanga.
Zotsatira zoyesera za ma formula opangidwa pansi pamikhalidwe ya labotale sizingakhale zotsatira zomaliza.Nthawi zambiri, pakhoza kukhala zovuta zina zaukadaulo zikayikidwa mukupanga, monga nthawi yayitali yophika, kusachita bwino kwa extrusion, zodzigudubuza zomatira, ndi zina zambiri. Izi zimafuna kusintha kwina kwa chilinganizo popanda kusintha momwe zinthu zimakhalira.
Nthawi zina pamafunika kusintha magwiridwe antchito pochepetsa pang'ono magwiridwe antchito amthupi ndi makina ndi magwiridwe antchito, zomwe zikutanthauza kusagwirizana pakati pa magwiridwe antchito amthupi ndi makina, magwiridwe antchito, magwiridwe antchito, ndi chuma, koma chofunikira ndikukwaniritsa zochepa. zofunika.Njira yopangira zida za mphira, ngakhale chinthu chofunikira, sichinthu chokhacho chokha, chomwe nthawi zambiri chimatsimikiziridwa ndi chitukuko chaukadaulo.
Kuwongolera kosalekeza kwa njira zopangira ndi ukadaulo wa zida kudzakulitsa kusinthika kwa zida za mphira, monga kuwongolera kutentha kolondola ndikukhazikitsa njira zopangira zopangira zokha, zomwe zimapangitsa kuti tizitha kukonza zida za mphira zomwe poyamba zinkawoneka kuti sizikuyenda bwino.Komabe, pakufufuza ndi kugwiritsa ntchito chilinganizo china, mikhalidwe yeniyeni yopangira ndi zomwe zikuchitika pano ziyenera kuganiziridwa.
M'mawu ena, wopanga mafomuwa sayenera kukhala ndi udindo pazabwino za chinthu chomwe chamalizidwa, komanso kulingaliranso mokwanira za kugwira ntchito kwa fomuyi munjira zosiyanasiyana zopangira zomwe zilipo kale.
