Kuba umwanda uri mumapaki ya ice biterwa ahanini nibikoresho byabo nimikoreshereze.Rimwe na rimwe, niba ibikoresho cyangwa ibikorwa byo gupakira urubura bitujuje ubuziranenge bwibiribwa, hashobora kubaho ibibazo byanduye.Dore bimwe mubyingenzi byingenzi:
1. Ibigize imiti:
-Bimwe mubipfunyika byujuje ubuziranenge bishobora kuba birimo imiti yangiza nka benzene na phalite (ikunda gukoreshwa cyane), bishobora guhungabanya ubuzima.Iyi miti irashobora kwinjira mubiribwa mugihe ikoreshwa, cyane cyane mubushyuhe bwo hejuru.
2. Ibyangiritse no kumeneka:
-Niba igikapu cya barafu cyangiritse cyangwa kimenetse mugihe cyo gukoresha, gel cyangwa amazi imbere birashobora guhura nibiryo cyangwa ibinyobwa.Nubwo ibyuzuza imifuka ya ice byinshi bidafite uburozi (nka polymer gel cyangwa igisubizo cya saline), guhuza ntibisanzwe.
3. Icyemezo cyibicuruzwa:
-Iyo uhisemo ipaki, reba icyemezo cyumutekano wibiribwa, nkicyemezo cya FDA.Izi mpamyabumenyi zerekana ko ibikoresho bya paki yubusa bifite umutekano kandi bikwiriye guhura nibiryo.
4. Gukoresha neza no kubika:
-Kwemeza isuku yipaki ya barafu mbere na nyuma yo kuyikoresha, kandi uyibike neza.Irinde kubana nibintu bikarishye kugirango wirinde kwangirika.
-Iyo ukoresheje ipaki ya barafu, nibyiza kuyishyira mumufuka utarimo amazi cyangwa ukayizinga nigitambaro kugirango wirinde guhura nibiryo.
5. Ibidukikije:
-Harebye kurengera ibidukikije, hashobora gutorwa udupapuro twinshi twa barafu, kandi hagomba kwitabwaho uburyo bwo gutunganya no kujugunya ibibarafu kugirango bigabanye ibidukikije.
Muri make, guhitamo ibipapuro byujuje ubuziranenge kandi byemewe bikwiye, no kubikoresha no kubibika neza, birashobora kugabanya ingaruka ziterwa n’umwanda.Niba hari ibibazo byihariye byumutekano, urashobora kugira ibisobanuro birambuye kubicuruzwa nibisobanuro byabakoresha mbere yo kugura.
Ibice byingenzi bigize paki ya firigo
Ibipapuro bikonjesha bikonjesha bigizwe nibikoresho byinshi byingenzi bigamije gutanga insulasiyo nziza kandi biramba.Ibikoresho by'ingenzi birimo:
1. Ibikoresho byo hanze:
-Nylon: Yoroheje kandi iramba, ikunze gukoreshwa kumurongo winyuma wibipapuro byujuje ubuziranenge.Nylon ifite imbaraga zo kurwanya no kurira.
-Polyester: Ikindi kintu gikunze gukoreshwa ibikoresho byo hanze, bihendutse gato ugereranije na nylon, kandi bifite igihe kirekire kandi birwanya amarira.
-Vinyl: Birakwiye kubisabwa bisaba kutagira amazi cyangwa byoroshye gusukura hejuru.
2. Ibikoresho byo kubika:
-Polyurethane ifuro: ni ibintu bisanzwe bikingira, kandi bikoreshwa cyane mumifuka ya barafu ikonjesha kubera imikorere myiza yubushyuhe bwumuriro nibiranga uburemere.
-Polystirene (EPS) ifuro: izwi kandi nka styrofoam, ibi bikoresho bikunze gukoreshwa mubisanduku bikonje byimukanwa hamwe nibisubizo bibikwa rimwe.
3. Ibikoresho by'imbere:
-Aluminum foil cyangwa metallised firime: bikunze gukoreshwa nkibikoresho byo gutondeka kugirango bifashe kwerekana ubushyuhe no gukomeza ubushyuhe bwimbere.
-Icyiciro cyiza cya PEVA (polyethylene vinyl acetate): Ibikoresho bya pulasitiki bidafite uburozi bikunze gukoreshwa murwego rwimbere rwimifuka ya barafu bihuye neza nibiryo, kandi birakunzwe cyane kuko bitarimo PVC.
4. Uzuza:
-Isakoshi ya gel: igikapu kirimo gel idasanzwe, ishobora gukomeza gukonjesha igihe kirekire nyuma yo gukonja.Gel isanzwe ikorwa no kuvanga amazi na polymer (nka polyacrylamide), rimwe na rimwe birinda no kurwanya antifreeze byongerwaho kunoza imikorere.
-Amazi yumunyu cyangwa ibindi bisubizo: Bimwe mubipfunyika byoroheje birashobora kuba birimo amazi yumunyu, bifite aho bikonjesha munsi y’amazi meza kandi birashobora gutanga igihe kinini cyo gukonjesha mugihe cyo gukonjesha.
Mugihe uhisemo igikapu gikonjesha gikwiye, ugomba gusuzuma niba ibikoresho byayo byujuje ibyo ukeneye, cyane cyane niba bisaba icyemezo cyumutekano wibiribwa, kandi niba igikapu cyibarafu gikenera isuku kenshi cyangwa gukoreshwa mubidukikije.
Ibice byingenzi bigize ibibarafu bikonje
Igipapuro cya barafu cyakonjeshejwe kigizwe nibice byingenzi bikurikira, buri kimwe gifite imirimo yihariye kugirango igenzure rya barafu ikonje ikomeza neza ubushyuhe buke:
1. Ibikoresho byo hanze:
-Nylon: Nylon ni ibintu biramba, bitarinda amazi, kandi byoroheje bikwiranye n’imifuka ya barafu ikonje bisaba kugenda kenshi cyangwa gukoreshwa hanze.
-Polyester: Polyester nikindi kintu gisanzwe kiramba gikunze gukoreshwa mugikonoshwa cyo hanze cyimifuka yubukonje bwakonje, hamwe nimbaraga nziza no kwambara birwanya.
2. Urwego rwo gukumira:
-Polyurethane ifuro: Nibikoresho bikora neza cyane, kandi bikoreshwa cyane mumifuka yubukonje bukonje kubera ubushobozi bwayo bwo kubika ubushyuhe.
-Polystirene (EPS) ifuro: izwi kandi nka styrene ifuro, ibi bikoresho byoroheje nabyo bikoreshwa mugukonjesha no gukonjesha ibicuruzwa, cyane cyane mubisubizo bikonjesha rimwe.
3. Imbere:
-Aluminum foil cyangwa metallised firime: Ibi bikoresho bikunze gukoreshwa nkimirongo ifasha kwerekana ingufu zubushyuhe no kongera ingaruka zokwirinda.
-Icyiciro cyiza cya PEVA: Iki nikintu cya plastiki kitagira uburozi gikunze gukoreshwa mugice cyimbere cyibipapuro bya barafu, bituma habaho guhura neza nibiryo.
4. Uzuza:
-Gel: Akenshi kuzuza kuzuza imifuka ya barafu yakonje ni gel, ubusanzwe irimo amazi, polymers (nka polyacrylamide) hamwe ninyongeramusaruro nkeya (nka preservatives na antifreeze).Iyi gel irashobora gukuramo ubushyuhe bwinshi kandi ikarekura buhoro buhoro ingaruka zo gukonja nyuma yo gukonja.
-Umuti wamazi yumunyu: Mubice bimwe byoroshye bya barafu, amazi yumunyu arashobora gukoreshwa nkigikonje kuko aho gukonjesha amazi yumunyu ari munsi yaya mazi meza, bigatanga ingaruka zo kumara igihe kirekire.
Mugihe uhisemo ibibarafu bikonje, ni ngombwa kwemeza ko ibikoresho byatoranijwe bifite umutekano, bitangiza ibidukikije, kandi bishobora guhaza ibyo ukeneye, nko kubungabunga ibiryo cyangwa intego zubuvuzi.Hagati aho, suzuma ubunini n'imiterere y'ibipapuro by'ibarafu kugirango urebe ko bikwiranye na kontineri yawe cyangwa ububiko bwawe.
