Mafuta amkati ndiofunikira pakukonzekera kwa PVC, akamasewera mbali yothetsa mphamvu ya mikangano pakati pa ma pvc moleclence. Kukhala Polar Mwachilengedwe, amawonetsa kugwirizana kwambiri ndi PVC, kuonetsetsa kupezeka kogwira mtima mu zinthu.
Chimodzi mwazopindulitsa kwambiri zamafuta a mkati ndi kuthekera kwawo kukhala kutali ndi kuwonekera kwambiri ngakhale pamlingo waukulu. Umboni uwu ndiwofunika kwambiri pakugwiritsa ntchito kumene kumveka bwino ndikofunikira, monga momwe zimakhalira ndi zida zowonekera kapena magalasi owala.
Ubwino wina ndikuti mafuta a mkati sakonda kutulutsa kapena kusamuka pamalo a PVC. Katundu wosakhalapo kusungulusa umawonetsetsa kuti ndi okwanira, ndipo amasindikiza zinthu zomaliza. Imalepheretsa kuphukira kwamkati ndikukhalabe ndi mtima wosagawanika, kuonetsetsa kusamalira bwino magwiridwe antchito.

Mafuta opangidwa ndi kunja ndi ofunikira pakukonzekera kwa PVC, akamasewera gawo lofunikira pakuchepetsa chitsando pakati pa PVC ndi chitsulo pamalo. Mafuta awa ndi omwe sakhala polar m'chilengedwe, ndi parafini ndi polyethylene amagwiritsa ntchito zitsanzo zogwiritsidwa ntchito. Kuthandiza kwa mafuta akunja kumadalira kutalika kwa kutalika kwa hydrocabobon chenicheni, nthambi zake, ndi kukhalapo kwa magulu ogwira ntchito.
Popeza mafuta okunja ndi opindulitsa pakukonzekera kusintha, mlingo wawo umayenera kulamuliridwa mosamala. Pamalingo wapamwamba, amatha kubweretsa zovuta zoyipa monga mitambo yomaliza ndikuthamangitsidwa mafuta pansi. Chifukwa chake, kupeza malire oyenera pakugwiritsidwa ntchito kwawo ndikofunikira kuonetsetsa kuti onsewa adasinthasintha kusinthasintha komanso kofunikira.
Mwa kuchepetsa zitsamba pakati pa pvc ndi chitsulo pamalopo, mafuta akunja amatsogolera kukonza kosayenera ndikuletsa zinthuzo kuti zisasunthike ku zida. Izi zimathandizira kuchita bwino pazopanga ndipo zimathandizanso kusunga umphumphu wa chinthu chomaliza.
Kuchuluka kwa ntchito
