Mafuta odzola
Zowonjezera Zodzoladzola Zogwira Ntchito Zambiri Zamakampani a PVC
| Mafuta odzola amkati TP-60 | |
| Kuchulukana | 0.86-0.89 g/cm3 |
| Chizindikiro cha refractive (80℃) | 1.453-1.463 |
| Kukhuthala (mPa.S, 80℃) | 10-16 |
| Mtengo wa Asidi (mgkoh/g) | 10 |

Mafuta odzola amkati ndi ofunikira kwambiri pakupanga PVC, chifukwa amagwira ntchito yofunika kwambiri pochepetsa mphamvu zokangana pakati pa unyolo wa mamolekyu a PVC, zomwe zimapangitsa kuti kukhuthala kusungunuke kuchepe. Popeza ndi polar, amafanana kwambiri ndi PVC, zomwe zimapangitsa kuti zinthu zonse zizifalikira bwino.
Chimodzi mwa ubwino wodziwika bwino wa mafuta odzola mkati ndi kuthekera kwawo kusunga mawonekedwe abwino ngakhale pamlingo wokwera. Kuwonekera bwino kumeneku ndikofunikira kwambiri pakugwiritsa ntchito komwe mawonekedwe owoneka bwino ndi ofunikira, monga m'mapepala owonekera bwino kapena magalasi owonera.
Ubwino wina ndi wakuti mafuta odzola amkati samatulutsa kapena kusamuka pamwamba pa chinthu cha PVC. Kapangidwe kameneka kopanda kutulutsa madzi kamatsimikizira kuti chinthu chomaliza chimawotcherera bwino, chimamatira, komanso chimasindikiza bwino. Chimaletsa kuphuka kwa pamwamba ndipo chimasunga umphumphu wa chinthucho, ndikuwonetsetsa kuti chikugwira ntchito bwino komanso kukongola kwake kukugwirizana.
| Mafuta odzola akunja TP-75 | |
| Kuchulukana | 0.88-0.93 g/cm3 |
| Chizindikiro cha refractive (80℃) | 1.42-1.47 |
| Kukhuthala (mPa.S, 80℃) | 40-80 |
| Mtengo wa Asidi (mgkoh/g) | 12 |
| Mtengo wa Ayodini (gl2/100g) | ＜2 |
Mafuta odzola akunja ndi zinthu zofunika kwambiri pakupanga PVC, chifukwa amathandiza kwambiri kuchepetsa kugwirizana pakati pa PVC ndi malo achitsulo. Mafuta amenewa nthawi zambiri samakhala ngati polar, ndipo parafini ndi polyethylene wax ndi zitsanzo zomwe zimagwiritsidwa ntchito kwambiri. Kugwira ntchito bwino kwa mafuta odzola akunja kumadalira kwambiri kutalika kwa unyolo wa hydrocarbon, nthambi zake, komanso kukhalapo kwa magulu ogwira ntchito.
Ngakhale mafuta odzola akunja ndi othandiza pakukonza bwino zinthu, mlingo wawo uyenera kulamulidwa mosamala. Pa mlingo waukulu, angayambitse zotsatira zoyipa monga kusowa kwa mitambo mu chinthu chomaliza komanso kutulutsa mafuta pamwamba. Chifukwa chake, kupeza bwino momwe amagwiritsidwira ntchito ndikofunikira kuti zitsimikizire kuti zinthuzo zikuyenda bwino komanso kuti zinthuzo zikhale ndi mawonekedwe abwino.
Mwa kuchepetsa kumamatira pakati pa PVC ndi malo achitsulo, mafuta odzola akunja amathandiza kukonza bwino ndikuletsa kuti zinthuzo zisamamatire ku zida zokonzera. Izi zimawonjezera magwiridwe antchito a njira yopangira zinthu ndipo zimathandiza kusunga umphumphu wa chinthu chomaliza.
Kukula kwa Ntchito
