Hari gahunda zimwe na zimwe zo kwamamaza tuzi ariko abantu benshi bashobora kugirwa mu ibanga. Urugero,
Hari sucrose 0 mu biribwa, ariko ntibivuze ko nta sukari irimo,
Hari ibinure 0 mu biribwa, ariko ntabwo bingana na karori.
Hari gahunda zimwe na zimwe zishobora kuvugwa ko bigoye kwirinda, nk'umurima w'icyuma gifunga cya silicone "icyatsi".Agapfundikizo k'"icyatsi" bivuga agapfundikizo karinda ibidukikije )
Ibifunga bya silikoni bimaze imyaka myinshi bikoreshwa mu bwubatsi, kandi bikunze gukoreshwa mu gufunga no gufatanya mu kubaka inkuta z'amarido, inzugi n'amadirishya, guteranya n'ahandi. Bitewe n'iterambere ry'imijyi, ibifunga bya silikoni byageze mu byiciro byose by'ubuzima. , Amatara, ibikoresho byo mu rugo n'ibindi bintu bito bigira uruhare rudashobora kwirengagizwa. Muri iki gihe, ibifunga bya silikoni biri gukoreshwa cyane, kandi ibyo abaguzi bakenera ku bifunga bya silikoni ntibigarukira gusa ku mirimo y'ibanze yo gufatanya no gufatanya. Muri icyo gihe, ibikorwa bya karuboni ebyiri byanashyize imbere ibisabwa bishya ku ibyuka byose bihumanya inyubako. Bitewe n'ibintu bibiri, ibifunga bya silikoni by'icyatsi kibisi kandi bitangiza ibidukikije byabaye ikintu gishya mu nganda.
Ibikenewe bishya byateye imbaraga amasoko mashya. Abaguzi basanzwe bagomba guhitamo bate ibifunga bya silikoni "byatsi" nyabyo?
Uyu munsi, turabona igisubizo hamwe nawe!
1. Ni ibihe bintu bigomba gufatwa nk'icyuma gifunga silicone "icyatsi" nyacyo?
Mbere yo gusobanura ibicuruzwa bifunga "icyatsi kibisi", tugomba kubanza gusobanukirwa icyo ibicuruzwa "cyatsi" ari cyo? Ubusanzwe ibyo twita "icyatsi kibisi" bigomba gupimwa hashingiwe ku bintu bine bigize ingufu, umutungo, ibidukikije n'ubwiza ("Amategeko Rusange yo Gusuzuma Ibicuruzwa Bihumanya" GB/T33761-2017).
Mu rwego rw'ibikoresho bifunga, imiterere ibiri y'ingufu n'umutungo ntacyo bigira ku mikorere y'ibikoresho bifunga bya silikoni. Ibidukikije n'ubwiza byabaye ibintu bibiri by'ingenzi mu gusuzuma niba ibikoresho bifunga bya silikoni ari "icyatsi". VOC nke, uburozi buke bw'umubiri, Ubwiza bwinshi (butari amavuta menshi) n'ibindi biri mu cyiciro cya byombi.
2. Ni gute wasobanura VOC nke? Ni iyihe ngingo ngenderwaho igezweho ku birebana n'aho ibikubiye muri VOC bigarukira?
Mu bice bibiri by’ibidukikije n’ubwiza, VOC nkeya ishobora kuvugwa ko ari kimwe mu bintu bizwi cyane ku bidukikije ku baguzi. Mu 2001, aya mahame y’igihugu yashyizeho amabwiriza asobanutse ku birebana n’aho ibintu byangiza bigarukira mu bikoresho bifunga imbere——
GB 18583 "Ibikoresho byo gushushanya imbere - Imipaka y'ibintu biteje akaga mu byuma bikometse"
GB 30982 "Imbibi z'ibintu biteje akaga mu byuma bikonjesha mu bwubatsi"
GB/T 33372 "Imbibi z'ibinyabutabire by'umwimerere bihindagurika mu byuma bikonjesha"
……
Ku ya 4 Werurwe 2020, Komite y'Igihugu ishinzwe Gutunganya Ibipimo Ngenderwaho yasohoye itegeko rishya rigenga GB 33372-2020 "Imbibi z'Ibinyabutabire Bihindagurika mu Bikoresho Bikometse", ryakomeje kugabanya ibisabwa ku bikoresho bikometse mu nzego zitandukanye. Ku bwoko bumwe bwa kole, agaciro k'ibipimo bya VOC gatandukanye na ko gatandukanywa hakurikijwe uko urwego rw'ibikoresho rumeze.
▼Umubare ntarengwa w'ibice bya kole binini bya VOC (GB 33372-2020)
3. Uretse VOC nkeya, ni gute wasobanura imiterere n'imikorere ya silikoni zifunga "icyatsi"?
01. Uburozi buke mu mubiri
Muri iki gihe, ibifunga bya silikoni bitagira aho bibohera ku isoko muri rusange bishobora kugabanywamo ibifunga byo mu bwoko bwa alcool na ketoxime hakurikijwe ibintu bito bisohora mu gihe cyo gucurisha. Ibifunga byo mu bwoko bwa alcool, molekile nto zirekurwa mu gihe cyo gucurisha muri rusange ni molekile nto za alcool nka methanol, ethanol (izwi cyane nka alcool), na molekile nto za ketoxime, molekile nto zirekurwa mu gihe cyo gucurisha muri rusange ni ketone oximes nka butanone oxime Molekile nto.
Ikizamini cy'uburozi bw'umubiri buhindagurika (Ingero z'ibimera)
Ubwoko bubiri bw'ibifunga n'ibimera bimwe byashyizwe ahantu hafunze mu gihe cy'iminsi 10, kandi ingaruka z'ubwoko butandukanye bw'ibifunga ku mikurire y'ibimera bimwe zarasuzumwe. Itandukaniro mu kurinda ibidukikije hagati y'ibifunga byo mu bwoko bwa alcool na ketoxime ryagereranyijwe n'uburozi bw'ibinyabuzima.
Ibisubizo by'igerageza ni ibi bikurikira:
Imyanzuro y’igerageza igaragaza ko utunyangingo duto tw’inzoga turekurwa mu gihe cyo gusimbuza inzoga ikoresheje alcool nta ngaruka mbi zigaragara ku mikurire y’ibimera, kandi ko ari indangagaciro ku bidukikije.
02. Agakoresho ko gufunga gafite ubuziranenge bwo hejuru
Bafite impungenge ku kurengera ibidukikije n'ubuzima bw'ibidukikije byo mu nzu,Siwayinama ikomeye ko abakoresha bahitamo ibikoresho byo gufunga bigezweho kandi byiza, kandi bakirinda kugura no gukoresha bimwe mu bikoresho byo hasi kandi bibi ku isoko, nk'ibikoresho byo gufunga byuzuye amavuta byuzuye amavuta y'umweru. Ntabwo biramba gusa, bizasaza, bimeneke, kandi biveho, ahubwo amavuta y'umweru yuzuyemo azakomeza gukwirakwira no guhindagurika, bigatera imyuka myinshi ya TVOC, bigira ingaruka ku bidukikije byo mu nzu, kandi imikorere yo kurengera ibidukikije ntishobora kwemezwa.
4. Ni gute wahitamo ikirango cy'icyuma gifunga "icyatsi"?
Mu ijambo rimwe:
Hitamo SIWAY gusa!
Nk'ikirango gikomeye mu nganda zikora ibifunga, SIWAY yahoraga yiyemeje iterambere rirambye, ritekanye kandi rirambye. Ku ruhande rumwe, yashyize mu bikorwa igitekerezo cy'iterambere ritangiza ibidukikije mu bushakashatsi no guteza imbere ibicuruzwa, igishushanyo mbonera cy'amafimu, amahame agenga ubuziranenge, no gukora ibintu mu buryo bw'ubwenge.
Ku rundi ruhande, inasubiza byimazeyo icyifuzo cyo "gutanga icyemezo cy’icyatsi kibisi", ifata kurengera ibidukikije nk'ingamba z'ingenzi z'iterambere ry'ikigo, kandi iyobora inganda mu bijyanye n'amahame agenga ibicuruzwa bihumanya ikirere. SIWAY yagiye yitabira mu gukusanya amahame ajyanye n'ibyo ikora nka GB/T 35609 "Ibikoresho bitagira amazi n'ibifunga by'icyatsi kibisi" n'amahame ya T/CECS 10029 "Isuzuma ry'Ibikoresho by'Ubwubatsi n'Ibifunga by'Ubwubatsi bihumanya ikirere", itanga ibisubizo byuzuye byo gufunga by'uburyo bwo gufunga byujuje ubuziranenge ku muguzi wese ukurikirana ubwiza n'ubwiza.
Ese umaze kubona ibi wasobanukiwe neza ibijyanye n'ibice by'icyatsi kibisi bya silikoni? Uracyashaka kumenya byinshi ku bijyanye n'ibicuruzwa, ndakwinginze utegereze guhura nawe mu gihe kizaza.
SIWAY irinda buri muguzi wese ikoresheje "icyatsi kibisi",
Komeza kwihangana, kurenga, no guha imbaraga icyiza.
