Inyongeramusaruro z'amavuta menshi mu nganda za PVC
| Amavuta yo mu mutwe TP-60 | |
| Ubucucike | 0.86-0.89 g/cm3 |

Amavuta yo mu nzu ni inyongeramusaruro z'ingenzi mu gutunganya PVC, kuko agira uruhare runini mu kugabanya imbaraga zo gushwanyagurika hagati y'iminyururu ya molekile za PVC, bigatuma ubushyuhe buke bushonga. Kubera ko ari polari mu miterere yayo, agaragaza ko ahuye cyane na PVC, bigatuma ikwirakwira neza mu bikoresho byose.
Imwe mu nyungu zigaragara z'amavuta yo mu nda ni ubushobozi bwayo bwo kugumana ubwiza buhebuje nubwo yaba ari menshi. Uku mucyo ni ingenzi cyane mu gukoresha aho ubwiza bw'amaso ari ngombwa, nko mu bikoresho bipfunyikamo cyangwa indorerwamo z'amaso.
Indi nyungu ni uko amavuta yo mu nzu adakunda gusohora cyangwa ngo yimukire ku buso bw'igicuruzwa cya PVC. Ubu buryo bwo kudasohora butuma igicuruzwa cya nyuma kirushaho kuba cyiza mu gusudira, gusiga kole no gucapa. Burinda ko ubuso bukura kandi bugakomeza ubuziranenge bw'igicuruzwa, butuma ubwiza n'imikorere bihoraho.
| Amavuta yo hanze TP-75 | |

Amavuta yo hanze ni inyongeramusaruro z'ingenzi mu gutunganya PVC, kuko agira uruhare runini mu kugabanya gufatana hagati ya PVC n'ubuso bw'icyuma. Aya mavuta ahanini ntafite imiterere ya polar, aho parafini na polyethylene ari ingero zikunze gukoreshwa. Ingufu zo gusiga amavuta yo hanze ahanini ziterwa n'uburebure bw'umuyoboro wa hydrocarbon, amashami yawo, ndetse no kuba hari amatsinda akora.
Nubwo amavuta yo hanze ari ingirakamaro mu kunoza imiterere y’uburyo atunganywa, ingano yayo igomba kugenzurwa neza. Iyo akoreshejwe ari menshi, ashobora gutera ingaruka mbi nko kuba ibicu mu gicuruzwa cya nyuma ndetse no gusohora amavuta ku buso. Bityo, gushaka uburinganire bukwiye mu ikoreshwa ryayo ni ingenzi kugira ngo habeho kunozwa uburyo bwo gutunganya ndetse n’imiterere y’umusaruro wifuzwa.
Mu kugabanya gufatana hagati y’ubuso bwa PVC n’ubw’icyuma, amavuta yo hanze yorohereza gutunganya neza no gukumira ibikoresho gufatana n’ibikoresho byo gutunganya. Ibi byongera imikorere myiza y’uburyo bwo gukora kandi bigafasha kugumana ubuziranenge bw’umusaruro wa nyuma.
Ingano y'ishyirwa mu bikorwa
