Mafuta odzola amkati ndiwowonjezera ofunikira pakukonza kwa PVC, chifukwa amagwira ntchito yofunika kwambiri pochepetsa kukangana pakati pa unyolo wa mamolekyu a PVC, zomwe zimapangitsa kusungunuka kusungunuka.Pokhala polar mwachilengedwe, amawonetsa kuyanjana kwakukulu ndi PVC, kuwonetsetsa kubalalitsidwa mogwira mtima pazinthu zonse.
Ubwino umodzi wodziwika wamafuta amkati ndi kuthekera kwawo kusunga kuwonekera bwino kwambiri ngakhale pamlingo waukulu.Kuwonekera kumeneku ndikofunikira kwambiri pamapulogalamu omwe kumveka bwino kowonekera ndikofunikira, monga pakuyika zinthu zowonekera kapena magalasi owoneka bwino.
Ubwino wina ndikuti mafuta amkati samakonda kutulutsa kapena kusamukira pamwamba pa chinthu cha PVC.Katundu wopanda exudation umatsimikizira kukhathamiritsa kwa kuwotcherera, gluing, ndi kusindikiza kwa chinthu chomaliza.Zimalepheretsa kufalikira kwapamwamba ndikusunga kukhulupirika kwa zinthuzo, kuonetsetsa kuti magwiridwe antchito ndi owoneka bwino.
| Mafuta akunja a TP-75 | |
| Kuchulukana | 0.88-0.93 g/cm3 |
| Refractive index (80 ℃) | 1.42-1.47 |
| Viscosity (mPa.S, 80 ℃) | 40-80 |
| Mtengo wa Acid (mgkoh/g) | ＜12 |
| Mtengo wa ayodini (gl2/100g) | ＜2 |
Mafuta akunja ndi ofunikira pakuwongolera kwa PVC, chifukwa amagwira ntchito yofunika kwambiri pochepetsa kumamatira pakati pa PVC ndi zitsulo.Mafuta odzolawa sakhala a polar m'chilengedwe, ndipo parafini ndi phula la polyethylene zimagwiritsidwa ntchito kwambiri.Kuchita bwino kwa mafuta akunja kumatengera kutalika kwa unyolo wa hydrocarbon, nthambi zake, komanso kupezeka kwamagulu ogwira ntchito.
Ngakhale mafuta odzola akunja ali opindulitsa pakuwongolera momwe zinthu zimapangidwira, mlingo wawo uyenera kuyang'aniridwa mosamala.Pa mlingo waukulu, angayambitse zotsatira zosafunika monga cloudiness mu mankhwala omaliza ndi exudation wa lubricant pamwamba.Chifukwa chake, kupeza kulinganiza koyenera pakugwiritsa ntchito kwawo ndikofunikira kuti muwonetsetse kuti zonse zikuyenda bwino komanso zomwe mukufuna kumapeto.
Pochepetsa kumamatira pakati pa PVC ndi zitsulo, mafuta akunja amathandizira kukonza bwino ndikulepheretsa kuti zinthuzo zisamamatire ku zida zopangira.Izi zimapangitsa kuti ntchito yopangira zinthu ikhale yabwino komanso imathandizira kusunga kukhulupirika kwa chinthu chomaliza.
Kuchuluka kwa Ntchito
