Twarabaye abahinguzi b’ibintu bazi utuntu n’utundi. Kubera ko twaronse ivyemezo vyinshi bihambaye vy’isoko ryayo ku bijanye n’uruganda rw’ubuntu rwitwa Bisphenol a CAS 80-05-7, turatera iteka umukuru wacu nyamukuru w’ubugororotsi mu bikorwa, imbere mu bikorwa kandi tuzokora uko dushoboye kwose kugira ngo duhe abaguzi bacu inyishu z’agaciro kanini n’ibikorwa vyiza cane.
Twarabaye abahinguzi b’ibintu bazi utuntu n’utundi. Gutsinda vyinshi mu vyemezo bihambaye vy’isoko ryayo ku , Dufata ingingo ku giciro ico ari co cose kugira ngo turonke ahanini ibikoresho n’uburyo bigezweho kuruta ibindi vyose. Ivyo gupakira ikimenyetso catowe ni ikindi kintu kidutandukanya. Inyishu zo kwizigira imyaka myinshi y’igikorwa ata ngorane zakwegereye abakiriya benshi cane. Ivyo bikoresho biraboneka mu migero myiza kandi mu buryo butandukanye, bikoreshwa mu buryo bwa siyansi bivuye mu bikoresho bitagiramwo ibinure. Ishobora gushikwako mu migero itandukanye n’ibisobanuro vy’uguhitamwo. Amafomu mashasha ni meza cane kuruta aya kera kandi arakundwa cane n’abaguzi benshi.

Ivyo kubika bisphenol A bikwiye gukikuza intumbero nyamukuru zo “gukingira ukubora, gutuma habaho umutekano, no kwirinda ingaruka mbi ku bidukikije”.

Ikoreshwa rya Bisfenoli A (BPA)

Bisphenol A (BPA) ni ikintu gihambaye cane co guhingura ibintu bifise uburemere burengeye ubw’abandi, ivyuma bita polycarbonates, n’ivyuma bita polyester bishobora guhangana n’ubushuhe bwinshi. Ikoreshwa kandi nk’ikintu co guhagarika PVC, ikintu co gukingira umubiri, ikintu co gufata UV, ikintu co kwica ibiherere ku mubiri, n’ibindi.
Kubera ko ari ikintu gishobora gukoreshwa mu buryo bwinshi, BPA ikoreshwa cane mu guhingura amarezine y’ivyuma vyitwa epoxy, amarezine y’ivyuma vyitwa polycarbonates, amarezine y’ivyuma vyitwa polyester, amarezine y’ivyuma vyitwa polyphénylene éther be n’ivyuma vyitwa polysulfone. Vyongeye, irakora nk’ikintu gihagarika umutima witwa polyvinyl chloride (PVC), ikaba ari ikintu gikingira umubiri gukomera mu mapulasitike, ikaba ari ikintu gikingira imishwarara y’izuba (UV), ikaba ari umuti wica ibikoko vyo mu buhinzi, be n’ikintu kigabanya ubusaza mu bikoresho vy’imipira.
Ikoreshwa kandi nk’ikintu co gukingira umubiri n’ugutuma ivyuma bimera neza mu marangi no mu marangi. Mu guhingura ibintu bifise ubuzima, BPA ikora nk’ikirungo nyamukuru co guhingura amaresine ya epoxy na polycarbonate, kandi ikoreshwa cane nk’ikintu gihambaye co guhingura ibintu bifise amamolekule menshi, be no mu bikoresho birwanya ugukura, mu bikoresho bitera amapulasitike, no mu bikoresho vy’uburimyi.

1. Ukwizigirwa mu gutanga n'ugukora neza
Ibirango vy'ingenzi:
Ingamba z'ububiko bw'ibintu ku kivuko ca Qingdao, Tianjin, na Longkou zifise 1.000+
toni z'ububiko ziboneka
68% vy’amategeko ashikirizwa mu misi 15; amategeko yihutirwa ashirwa imbere biciye mu gutwara ibintu vyihuta
umurongo (30% vyihuta)
2. Uburyo n'Ukurikiza Amabwirizwa
Ivyemezo:
Ivyemezo bitatu hakurikijwe ingingo za REACH, ISO 9001, na FMQS
Ivyubahiriza amabwirizwa y’isuku kw’isi yose; 100% igitigiri c'ugusohoka muri duwane ku
Ivyo Uburusiya buva hanze
3. Inzego z'umutekano w'ibikorwa
Inyishu zo kwishura:
Amajambo ashobora guhinduka: LC (ukubona/igihe), TT (20% imbere + 80% iyo woherejwe)
Ivyiyumviro vyihariye: LC y’imisi 90 ku masoko yo muri Amerika y’Epfo; Uburasirazuba bwo Hagati: 30%
ibiziga + BL kwishura
Gutorera umuti amatati: amasaha 72 y'inyishu ku matati ajanye n'itegeko
4. Ibikorwa remezo vy'uruhererekane rw'ibikoresho
Urubuga rw'ivy'ubuhinga bwinshi:
Ugutwara ibintu mu ndege: Gushikana imisi 3 ku vyoherezwa muri Tayilande
Ugutwara abantu n'ibintu: Inzira yihariye y'ivyuma bita calcium formate ija mu Burusiya biciye mu nzira z'i Eurasia
ISO TANK Inyishu: Ugutwara imiti y’amazi (nk’akarorero, aside ya propionic ku
Ubuhindi)
Gupakira neza:
Ubuhinga bwa Flexitank: 12% kugabanya igiciro ca ethylene glycol (ugereranije n'ingoma ya kera
gupfunyika)
Ubwubatsi-urwego rwa calcium formate/Sodium Hydrosulfide: Ubukonje bushobora guhangana n'ibilo 25 vy'imifuko ya PP
5. Amasezerano yo kugabanya ingorane
Kugaragara kuva ku mpera kugeza ku mpera:
Gukurikirana GPS mu gihe nyaco ku birungikwa mu bikoresho
Ibikorwa vy'igenzura ry'uwundi muntu ku vyambu vy'aho umuntu aja (nk'akarorero, aside acetique yoherezwa muri Afirika y'epfo)
Inyuma y'ugucuruza:
Iminsi 30 y'uburyo bwiza n'uburyo bwo gusubirira/gusubiza amahera
Ubushuhe bwo kugenzura ubushuhe bw'ibiti ku bikoresho vyoherezwa mu bikoresho vy'amazi

Bisphenol a na 80-05-7 Uburyo bwo gukora
Bisphenol A 80-05-7 ikoreshwa mu gukoranya phenol na acetone bikoresheje aside sulfurique, aside hydrochlorique canke amaresine ahindura iyon.
