Ihe na-achịkwa ụfụfụ PVC nwere ike inyere anyị aka iweta ezigbo ihe onwunwe n'oge mmepụta na nhazi nke PVC, na-eme ka mmeghachi omume anyị gaa n'ihu nke ọma ma mepụta ngwaahịa anyị chọrọ. Agbanyeghị, anyị kwesịkwara ịṅa ntị n'ọtụtụ isi ihe njikwa ụlọ ọrụ dị mkpa mgbe anyị na-emepụta ya, ka mmeghachi omume anyị wee nwee ike ịga n'ihu nke ọma.
A na-ekewa usoro ịkpụzi ụfụfụ plastik nke ihe na-achịkwa ụfụfụ PVC ụzọ atọ: nhazi nke isi afụ, mgbasa nke isi afụ, na ime ka ahụ ụfụfụ sie ike. Maka mpempe akwụkwọ ụfụfụ PVC nwere ihe ndị na-eme ka ụfụfụ kemịkalụ dịkwuo mma, mmụba nke nuclei afụ nwere mmetụta dị mkpa na ịdị mma nke mpempe akwụkwọ ụfụfụ ahụ. PVC bụ nke molekul yinye kwụ ọtọ nwere obere agbụ molekul na ike ịgbaze dị ala. N'oge usoro ịgbasa isi afụ n'ime afụ, agbaze ezughị iji kpuchie afụfụ ahụ, gas ahụ na-adịkwa mfe ịgbasa ma jikọta ya na nnukwu afụfụ, na-ebelata ịdị mma nke mpempe akwụkwọ ụfụfụ ahụ.
Isi ihe dị mkpa iji melite mma nke ihe ndozi ụfụfụ PVC bụ ime ka ike ịgbaze nke PVC dịkwuo mma. Site na nyocha nke njirimara nhazi nke ihe polymer, enwere ụzọ dị iche iche iji melite ike ịgbaze nke PVC, mana ụzọ kachasị mma bụ ịgbakwunye ihe mgbakwunye nke na-eme ka ike ịgbaze dịkwuo mma ma belata okpomọkụ nhazi. PVC bụ nke ihe amorphous, ike ịgbaze ya na-ebelata ka okpomọkụ ịgbaze na-abawanye. N'aka nke ọzọ, ike ịgbaze ya na-abawanye ka okpomọkụ ịgbaze na-ebelata, mana mmetụta oyi dị oke ma na-eje ozi naanị dị ka ọrụ enyemaka. Ndị na-emepụta ACR niile nwere mmetụta nke ime ka ike ịgbaze dịkwuo mma, nke na-abawanye ka ọdịnaya njikwa ụfụfụ na-abawanye. N'ikwu ya n'ozuzu, ọ bụrụhaala na skru ahụ nwere ikike ịgbasa na ịgwakọta zuru oke, itinye ihe ndozi ụfụfụ dị elu nwere mmetụta dị ukwuu na ime ka ike nke agbaze dịkwuo mma.
Ihe dị n'elu bụ obere okwu mmalite maka isi ihe dị mkpa gbasara njikwa usoro ụfụfụ maka ihe ndị na-agbanwe ụfụfụ PVC. Mgbe anyị na-emepụta ha, anyị kwesịrị ilebara anya na nhazi, mmụba, na ọgwụgwọ nke nuclei afụ ha ma chịkwaa ha nke ọma.
