Ni ibihe biranga Polypropylene (PP)?

Zimwe mu ngingo z'ingenzi za polypropylene ni izi zikurikira:
1. Ubudahangarwa ku binyabutabire: Imisemburo n'aside byavanzwe ntibikunze guhuzwa na polypropylene, ibi bigatuma iba amahitamo meza ku bikoresho birimo ibyo bintu, nk'ibikoresho byo gusukura, ibikoresho by'ubutabazi bw'ibanze, n'ibindi.
2. Gukomera no gukomera: Polypropylene ikora neza ku buryo ihinduka mu buryo runaka (nk'ibindi bikoresho byose), ariko izahura n'ingaruka mbi za pulasitiki mu ntangiriro z'uburyo ihinduka, bityo muri rusange ifatwa nk'ikintu "kikomeye". Gukomera ni ijambo ry'ubuhanga risobanurwa nk'ubushobozi bw'ikintu bwo guhindura imiterere (nk'uko plastike ibikora, ntabwo ari ukubihindura imiterere) kitavunitse.
3. Kurwanya umunaniro: Polypropylene igumana ishusho yayo nyuma yo gucika intege cyane, gupfukama, cyangwa gukonja. Iyi miterere ni ingenzi cyane mu gukora imigozi y'ubuzima.
4. Gukingira: polypropylene ifite ubudahangarwa bukomeye ku mashanyarazi kandi ni ingirakamaro cyane ku bikoresho by'ikoranabuhanga.
5. Kohereza: Nubwo Polypropylene ishobora gukorwa ibonerana, ubusanzwe ikorwa kugira ngo ibe idahinduka mu buryo busanzwe. Polypropylene ishobora gukoreshwa mu bikorwa aho kohereza urumuri ari ingenzi cyangwa aho rufite agaciro gakomeye. Niba hari kohereza urumuri rwinshi, pulasitiki nka Acrylic cyangwa Polycarbonate ni amahitamo meza.
Polypropylene ishyirwa mu cyiciro cya "thermoplastic" (bitandukanye na "thermoset"), ibi bikaba bifitanye isano n'uburyo plastiki ikira ubushyuhe. Ibikoresho bya thermoplastic biba amazi iyo bishongeshejwe (hafi dogere selisiyusi 130 kuri polypropylene).
Ikintu cy'ingenzi ku bijyanye na thermoplastics ni uko zishobora gushyushywa kugeza aho zishongesha, zigakonjeshwa, hanyuma zikongera gushyushywa nta kwangirika gukomeye. Aho gushya, thermoplastics nka polypropylene zirashonga, bigatuma zishobora gushyirwamo mu buryo bworoshye hanyuma zikaza kongera gukoreshwa.
Mu buryo bunyuranye, plastike za thermoset zishobora gushyushywa rimwe gusa (ubusanzwe mu gihe cyo gushushanya inshinge). Gushyushya kwa mbere bituma ibikoresho bya thermoset bikomera (nk'uko epoxy y'ibice 2) bigatera impinduka mu buryo bw'imiti idashobora gusubizwa inyuma. Iyo ugerageje gushyushya plastike ya thermoset ku bushyuhe bwinshi ku nshuro ya kabiri byahitaga bishya. Iyi miterere ituma ibikoresho bya thermoset bitagomba kongera gukoreshwa.
