Momwe mungachepetse mtengo wa mphira
Mu dziko lopikisana kwambiri la malonda achubu, mtengo wowonjezera ndizofunikira kwambiri kuti chipambane chachuma cha chinthu. Ndikotheka kupanga njira yolumikizirana yomwe imakumana ndi zofunikira za kasitomala malinga ndi magwiridwe antchito onse, koma amakanidwa ndi kasitomala chifukwa ndiokwera mtengo kwambiri.
Kuphatikiza apo, zinthu za mphira nthawi zambiri zimagulitsidwa ndi voliyumu m'malo mopepuka (zopangidwa ndi zopangidwira nthawi zambiri zimakhazikika). Chifukwa chake, nkomveka kufanizira 'mtengo pa voliyumu ' osati mtengo wa 'wa ' wa mphira.
Zochitika zotsatirazi zitha kuchepetsa mtengo wachuma. Chidziwitso: Zochitika zonsezi zoyeserera sizingagwire ntchito iliyonse. Kusiyana kulikonse komwe kumachepetsa mtengo kumakhudzanso zinthu zina, zabwino kapena zoyipa.
1. Carbon wakuda / pulasitiki
Kusankha kaboni yakuda ndikugwiritsa ntchito mafuta ofalikira kwambiri kumasunga modulus ya kuchuluka kwa mtengo pomwe mtengo wake umatsika.
2. Kuchuluka kwa kaboni wakuda
Ganizirani za kusankha malo otsika ndi malo otsika carbor wakuda, chifukwa chakuda cha carbor sichikhala chotsika mtengo, komanso kumakhala kotentha kwambiri, komwe kumatha kuchepetsa mtengo wa mphira.
Sankhani mtundu wakuda wopangidwa ndi mpweya wokhazikika, chifukwa umatha kudzazidwa kwambiri, zomwe zimatha kuchepetsa mtengo wa mphira.
Sankhani malo otsika kwambiri ndi kaboni wakuda kuti mudzaze rabar wambiri, ndikusunga mamasukidwe okwera kwambiri, kotero kuti rabaya imatha kukhala yokwezeka kwambiri, kotero kuti rabaya ikhoza kukhala jakisoni wokwezeka kapena wopanda mawonekedwe ndi njira zina, ndipo mtengo wake udzachepetsedwa pang'ono.
3. Silica
Kutsutsana kotsika komanso kukana kwabwino, silika nthawi zambiri kumagwiritsidwa ntchito ngati filler ndipo ojambula ojambula amagwiritsidwa ntchito. Othandizira a Silne Coppling ndiokwera mtengo, ndipo ngati ochepa ophatikizira a Silne angagwiritsidwe ntchito ndipo magwiridwe antchito aphatikizidwe sangakhale osinthika, mtengo wa pawiri umatha kuchepetsedwa kwambiri. Njira yodziwika bwino ndikugwiritsa ntchito silica yokhala ndi ma hydroxyl, monga momwe amaphunzirira kuti aziphatikizidwa mosavuta. Chifukwa chake, ndi magulu ambiri a hydroxyl mu compound, yochepa yophatikiza imilane yofunikira imafunikira ndipo zomwezo zimasungidwa pomwe mtengo wake umachepetsedwa.
4. Filler
Mu mankhwala odzaza ndi tivi2-oyera otsika mtengo (monga dongo losambitsa madzi, calcium carbonate, eyiti),
Mu silika yodzaza ndi silika yodzaza ndi silika wakuda wa kaboni-sica ya silika amathanso kuchepetsa kuchuluka kwa wothandizira, chifukwa amatha kuchepetsa kuchuluka kwa wothandizila ku Silane, komanso kuchepetsa njira yochizira kutentha.
Kudzaza mphira ndi calcium carbonate kwambiri kumachepetsa mtengo wa mphira. Momwemonso, dongo limachepetsa kwambiri mtengo wa zomatira.
Ngakhale kuchepa kwa talc (2.7g / cm3) ndikokulirapo kuposa kaboni wakuda (1.8g / cm3), ngati magawo) a Talc akukhala akuda, mtengo wa pawiri umatha kuchepetsedwa. Kuphatikiza apo, ufa wa talc udzawonjezera liwiro lopitilira ndikuwongolera, zomwe zimachepetsa pang'ono mtengo.
5. Kuchepetsa kachulukidwe
Zinthu za mphira nthawi zambiri zimakhala zamtengo chifukwa cha kuchuluka osati kulemera. Ngati mungasinthe mawonekedwe a mphira kuti muchepetse kachulukidwe, pomwe kusunga mtengo pa voliyumu yopanda malire, ndiye kuti mutha kuchepetsa mtengo wake. Mwachitsanzo, pokonzanso cr ndi zbs, mtengo wake uliwonse wa madontho a rabara, amaperekanso kusintha kwina kwa mphira kuti asathere phindu la mtengowu.
6. Alowa m'malo mwa magawo awiri ophatikizira ndi zowonjezera.
Ngati ndi kotheka, muzikonzanso magawo awiri ndi gawo limodzi pogwiritsa ntchito njira zowongolera mphamvu ndi njira yoyeserera mphamvu zingathenso kuchepetsa mtengo.
7.. Kukonza Edzi
Kugwiritsa ntchito Edzi kumatha kusintha zowonjezera kapena kuthamanga kwa mtengo, motero kuchepetsa mtengo.
8. Fkm / acm kuphatikiza
Kusinthanso fkm yoyera ndi ma a ACM kuphatikiza (Dai-El AG-1530) kumapangitsa kuti mphira ukhale ndi kutentha kwabwino ndi kukana mafuta.
