Niba ushaka kurinda ibicuruzwa byawe umutekano n'umutekano wo kugurisha, ushobora kuba umaze kubona ko firime igabanya ishobora kugufasha kubikora.Hano hari ubwoko bwinshi bwa firime zigabanuka kumasoko uyumunsi rero ni ngombwa kubona ubwoko bwiza.Ntabwo guhitamo gusa ubwoko bukwiye bwa firime yo kugabanya bizafasha kurinda ibicuruzwa byawe ku gipangu, ariko kandi bizamura uburambe bwo kugura abakiriya bawe cyangwa abaguzi.
Mu bwoko bwinshi bwa firime zigabanuka, ubwoko butatu bwingenzi bwa firime kumasoko uzashaka gusubiramo ni PVC, Polyolefin, na Polyethylene.Izi firime zigabanya buriwese afite imitungo yambukiranya porogaramu zitandukanye, ariko ibiranga umwihariko wizi firime birashobora gutuma bikwiranye no gukoresha byumwihariko.
Hano hari imbaraga nintege nke za buri bwoko bwa firime zigabanuka kugirango bigufashe guhitamo imwe ishobora kuba nziza kubyo usaba.
● PVC (izwi kandi nka Polyvinyl Chloride)
Imbaraga
Iyi firime iroroshye, iroroshye, kandi yoroheje, mubisanzwe ihendutse kuruta firime nyinshi zigabanuka.Igabanuka mu cyerekezo kimwe gusa kandi irwanya cyane kurira cyangwa gutobora.PVC ifite icyerekezo gisobanutse, kirabagirana, bigatuma gishimisha ijisho.
Intege nke
PVC yoroshya kandi ikabyimba niba ubushyuhe bwiyongereye cyane, kandi bigakomera kandi bikavunika iyo bibaye ubukonje.Kubera ko firime irimo chloride, FDA yemeye gusa firime ya PVC kugirango ikoreshwe nibicuruzwa bitemewe.Ibi kandi bitera gusohora imyotsi yuburozi mugihe cyo gushyushya no gufunga, bigatuma biba ngombwa kuyikoresha ahantu hafite umwuka mwiza.Iyi firime rero nayo ifite amahame akomeye yo kujugunya.PVC ntabwo isanzwe ikwiranye no guhuza ibicuruzwa byinshi.
Ole Polyolefin
Imbaraga
Ubu bwoko bwa firime bugabanuka ni FDA yemerewe guhuza ibiryo kuko idafite chloride, kandi itanga umunuko muke mugihe cyo gushyushya no gufunga.Nibyiza bikwiranye nububiko butemewe kuburyo bugabanuka cyane.Filime ifite ubuso bwiza, burabagirana kandi irasobanutse bidasanzwe.Bitandukanye na PVC, irashobora kwihanganira urwego runini rwimihindagurikire yubushyuhe iyo ibitswe, ikabika ibarura.Niba ukeneye guhuza ibintu byinshi, polyolefin ni amahitamo meza.Bitandukanye na PE, ntishobora gupfunyika paki nyinshi yibintu biremereye.Polyolefin ihujwe nayo irahari byongera imbaraga zayo zititanze neza.Polyolefin nayo irashobora gukoreshwa 100%, bigatuma ihitamo "icyatsi".
Intege nke
Polyolefin ihenze kuruta firime ya PVC, kandi irashobora kandi gusaba gutobora mubisabwa bimwe kugirango wirinde umufuka wikirere cyangwa hejuru yubutaka.
● Polyethylene
Amwe mumakuru yinyongera: Filime ya polyethylene irashobora gukoreshwa muguhagarika firime cyangwa kurambura firime, ukurikije imiterere.Uzakenera kumenya ifishi ukeneye kubicuruzwa byawe.
Ababikora bakora polyethylene mugihe wongeyeho Ethylene muri polyolefin mugihe cya polymerisation.Hariho uburyo butatu bwa Polyethylene: LDPE cyangwa Polyethylene nkeya, LLDPE cyangwa Linear Umuvuduko ukabije wa Polyethylene, na HDPE cyangwa polyethylene yuzuye.Buri kimwe gifite porogaramu zitandukanye, ariko mubisanzwe, ifishi ya LDPE ikoreshwa mukugabanya gupakira firime.
Imbaraga
Nibyiza byo gupfunyika paki nyinshi yibintu biremereye-urugero, umubare munini wibinyobwa cyangwa amacupa yamazi.Iramba cyane kandi irashobora kurambura kurusha izindi firime.Kimwe na polyolefin, polyethylene ni FDA yemerewe guhuza ibiryo.Mugihe firime ya PVC na polyolefin igarukira mubyimbye, mubisanzwe bigera kuri 0.03mm gusa, polyethylene irashobora gupimwa kugeza kuri 0.8mm, bigatuma biba byiza gupfunyika ibinyabiziga nkubwato bwo kubika.Imikoreshereze itandukanye kuva ibiryo byinshi cyangwa bikonje kugeza kumifuka yimyanda hamwe na palletizing nko gupfunyika.
Intege nke
Polyethylene yagabanutseho hafi 20% -80% kandi ntabwo isobanutse nkizindi firime.Polyethylene iragabanuka mugihe ikonje imaze gushyuha, bigatuma biba ngombwa kugira umwanya winyongera wo gukonjesha kumpera yumurongo wawe ugabanuka.
