Ukadaulo wopangira mphira umalongosola njira yosinthira zinthu zosavuta kukhala zopangira mphira zomwe zimakhala ndi mawonekedwe apadera komanso mawonekedwe. Zomwe zili zazikulu zikuphatikiza:
- Rubber compounding system:
Njira yophatikizira mphira yaiwisi ndi zowonjezera kutengera zofunikira pazantchito, poganizira zinthu monga kukonza luso laukadaulo komanso mtengo wake. The general coordination system ikuphatikizapo mphira yaiwisi, vulcanization system, reinforcement system, protective system, plasticizer system, etc. Nthawi zina imaphatikizaponso machitidwe ena apadera monga lawi retardant, coloring, foaming, anti-static, conductive, etc.
1) Raba yaiwisi (kapena yogwiritsidwa ntchito limodzi ndi ma polima ena): zinthu za makolo kapena matrix
2) Vulcanization dongosolo: Dongosolo kuti mankhwala interacts ndi macromolecules mphira, kusintha mphira kuchokera liniya macromolecules mu mawonekedwe azithunzithunzi maukonde dongosolo, kuwongolera katundu mphira ndi kukhazikika morphology ake.
3) Makina owonjezera owonjezera: Kuwonjezera zida zolimbikitsira monga kaboni wakuda kapena zodzaza zina ku mphira, kapena kukonza makina ake, kukonza magwiridwe antchito, kapena kuchepetsa mtengo wazinthu.
4) Chitetezo: Onjezani anti-kukalamba kuti muchedwetse kukalamba kwa mphira ndikuwongolera moyo wantchito wazinthu.
5) Plasticizing dongosolo: amachepetsa kuuma kwa mankhwala ndi mamasukidwe akayendedwe a mphira wosakanizika, ndi bwino processing ntchito.
- Ukadaulo waukadaulo wa Rubber:
Ziribe kanthu kuti mphira umakhala wotani, uyenera kudutsa njira ziwiri: kusakaniza ndi vulcanization. Pazinthu zambiri za mphira, monga ma hose, matepi, matayala, ndi zina zotero, ziyeneranso kudutsa njira ziwiri: kugudubuza ndi kutulutsa. Kwa rabara yaiwisi yokhala ndi kukhuthala kwa Mooney, iyeneranso kupangidwa. Chifukwa chake, njira yoyambira komanso yofunika kwambiri pakukonza mphira imaphatikizapo magawo awa:
1) Kuyenga: kuchepetsa kulemera kwa mamolekyu a rabara yaiwisi, kukulitsa pulasitiki, ndikuwongolera magwiridwe antchito.
2) Kusakaniza: Sakanizani zigawo zonse mu chilinganizo mofanana kuti mupange mphira wosakanikirana.
3) Kugubuduza: Njira yopangira zinthu zomalizidwa pang'ono mwa kusakaniza mphira kapena kugwiritsa ntchito zida za chigoba monga nsalu ndi mawaya achitsulo pogwiritsa ntchito kukanikiza, kuumba, kumanga, kupukuta, ndi gluing.
4) Kukanikiza: Njira yokankhira zinthu zomwe zatsirizidwa ndi magawo osiyanasiyana osiyanasiyana, monga machubu amkati, mapondedwe, zipupa zam'mbali, ndi ma hoses amphira, kuchokera mu rabara wosakanikirana kudzera pakamwa.
5) Vulcanization: sitepe yomaliza mu mphira processing, zomwe zimaphatikizapo anachita mankhwala a macromolecules mphira kutulutsa mtanda yolumikizira pambuyo kutentha, kuthamanga, ndi nthawi.
