Pali njira zina zotsatsira malonda zomwe timazidziwa bwino koma anthu ambiri sadziwa zambiri. Mwachitsanzo,
Mu chakudya mulibe sucrose, koma sizikutanthauza kuti mulibe shuga,
Mu chakudya mulibe mafuta okwanira, koma si mafuta okwanira ma calories.
Machitidwe ena anganenedwe kuti ndi ovuta kuwapewa monga gawo la silicone "green" sealant.Chosindikizira "chobiriwira" chimatanthauza chosindikizira choteteza chilengedwe )
Zomatira za silicone zakhala zikugwiritsidwa ntchito pomanga kwa zaka zambiri, ndipo nthawi zambiri zimagwiritsidwa ntchito potseka ndi kulumikiza pomanga makoma a nsalu, zitseko ndi mawindo, misonkhano ndi minda ina. Chifukwa cha kupita patsogolo kwa mizinda, zomatira za silicone zalowa m'mbali zonse za moyo. , Kuunikira, zipangizo zapakhomo ndi zinthu zina zobisika zimagwira ntchito yomwe singayang'aniridwe. Pakadali pano, zomatira za silicone zikugwiritsidwa ntchito kwambiri, ndipo zofunikira za ogula pa zomatira za silicone sizimangokhala pa ntchito zomangirira ndi kutseka. Nthawi yomweyo, ntchito ya double carbon yaperekanso zofunikira zatsopano pa kutulutsa mpweya wonse m'nyumba. Pansi pa zinthu ziwiri, zomatira za silicone zobiriwira komanso zoteteza chilengedwe zakhala njira yatsopano mumakampani.
Zofuna zatsopano zalimbikitsa misika yatsopano. Kodi ogula wamba ayenera kusankha bwanji silicone sealants yeniyeni "yobiriwira"?
Lero, tikupeza yankho limodzi nanu!
1. Kodi ndi zinthu ziti zomwe ziyenera kuonedwa ngati silicone sealant yeniyeni "yobiriwira"?
Tisanafotokoze zinthu zotchingira "zobiriwira", choyamba tiyenera kumvetsetsa kuti chinthu "chobiriwira" ndi chiyani? Kawirikawiri zomwe timatcha zinthu "zobiriwira" ziyenera kuweruzidwa kuchokera ku makhalidwe anayi a mphamvu, zinthu, chilengedwe ndi khalidwe ("General Rules for Green Product Evaluation" GB/T33761-2017).
Mu gawo la zotsekera, makhalidwe awiriwa a mphamvu ndi zinthu sizikhudza kwambiri magwiridwe antchito obiriwira a zotsekera za silicone. Malo ndi khalidwe lakhala makhalidwe awiri ofunikira kwambiri poyesa ngati zotsekera za silicone ndi "zobiriwira". VOC yochepa, poizoni wochepa wa thupi, Ubwino wapamwamba (osati mafuta owonjezera) ndi zina zotero zimagwera m'gulu la zonse ziwiri.
2. Kodi mungatanthauze bwanji VOC yochepa? Kodi muyezo waposachedwa kwambiri wokhudza malire a zomwe zili mu VOC ndi uti?
Pakati pa zinthu ziwiri zomwe zimapangitsa kuti chilengedwe chikhale bwino komanso kuti chikhale chotsika, VOC yochepa ndi imodzi mwa zinthu zomwe anthu ambiri amaona kuti ndi zachilengedwe. Kuyambira mu 2001, miyezo ya dziko lonseyi yafotokoza momveka bwino zofunikira pa kuchepetsa zinthu zoopsa zomwe zimayikidwa mu zomangira zokongoletsera mkati——
GB 18583 "Zipangizo Zokongoletsera M'kati - Malire a Zinthu Zoopsa mu Zomatira"
GB 30982 "Malire a Zinthu Zoopsa mu Zomatira Zomangira"
GB/T 33372 "Malire a Zosakaniza Zachilengedwe Zosasinthika mu Zomatira"
……
Pa 4 Marichi, 2020, Komiti Yoyang'anira Kukhazikika kwa Dziko Lonse idatulutsa muyezo watsopano wa GB 33372-2020 "Malire a Zosakaniza Zachilengedwe Zosakhazikika mu Zomatira", womwe udagawanso zofunikira za zomatira m'magawo osiyanasiyana ogwiritsira ntchito. Pa mtundu womwewo wa zomatira, malire osiyanasiyana a VOC amasiyanitsidwanso malinga ndi momwe zinthu zilili m'magawo osiyanasiyana ogwiritsira ntchito.
▼Malire a kuchuluka kwa zomatira za VOC (GB 33372-2020)
3. Kuwonjezera pa VOC yochepa, kodi mungatanthauzire bwanji makhalidwe ena onse ndi magwiridwe antchito a silicone sealants "obiriwira"?
01. Kuchepa kwa poizoni m'thupi
Pakadali pano, zomatira zazikulu za silicone zomwe sizili ndi mbali pamsika zimatha kugawidwa m'magulu awiri: zomatira zamtundu wa mowa ndi ketoxime malinga ndi zinthu zazing'ono zomwe zimatulutsidwa panthawi yothira. Zomatira zamtundu wa mowa, mamolekyu ang'onoang'ono omwe amatulutsidwa panthawi yothira nthawi zambiri amakhala mamolekyu ang'onoang'ono a mowa monga methanol, ethanol (yomwe imadziwika kuti mowa), ndi zomatira zamtundu wa ketoxime, mamolekyu ang'onoang'ono omwe amatulutsidwa panthawi yothira nthawi zambiri amakhala ketone oximes monga butanone oxime.
Mayeso Oopsa a Thupi (Zitsanzo za Zomera)
Mitundu iwiri ya zotsekera ndi zomera zomwezo zinayikidwa pamalo otsekedwa kwa masiku 10, ndipo mphamvu ya mitundu yosiyanasiyana ya zotsekera pakukula kwa zomera zomwezo inafufuzidwa. Kusiyana kwa kuteteza chilengedwe pakati pa zotsekera zamtundu wa mowa ndi ketoxime kunayerekezeredwa ndi poizoni wa zamoyo.
Zotsatira za kuyesera ndi izi:
Zotsatira za kafukufukuyu zikusonyeza kuti mamolekyu ang'onoang'ono a mowa omwe amatulutsidwa panthawi yokonza sealant yokhala ndi mowa alibe zotsatirapo zoyipa pakukula kwa zomera, ndipo ndi abwino kwambiri kwa chilengedwe.
02. Chosindikizira chapamwamba kwambiri
Poganizira za chitetezo cha chilengedwe ndi thanzi la nyumba,SiwayAmalimbikitsa kwambiri kuti ogwiritsa ntchito asankhe zinthu zapamwamba komanso zapamwamba zotsekera, ndikupewa kugula ndikugwiritsa ntchito zinthu zina zotsika mtengo komanso zosalimba zomwe zili pamsika, monga zotsekera zodzaza mafuta zodzazidwa ndi zotsekera mafuta oyera. Sikuti zimangokhalira kulimba, zimakalamba, zimasweka, komanso zimatuluka, komanso mafuta oyera omwe amadzazidwamo adzapitiriza kufalikira ndi kusinthasintha, zomwe zimapangitsa kuti mpweya wambiri wa TVOC utuluke, zomwe zimakhudza chilengedwe chamkati, ndipo chitetezo cha chilengedwe sichingatsimikizidwe.
4. Kodi mungasankhe bwanji mtundu wa sealant "yobiriwira"?
Mwachidule:
Ingosankhani SIWAY!
Monga kampani yotsogola mumakampani opanga zinthu zomatira, SIWAY nthawi zonse yakhala ikudzipereka ku chitukuko chotetezeka, chobiriwira, komanso chathanzi. Kumbali imodzi, yakhala ikutsatira bwino lingaliro la chitukuko chobiriwira munjira yonse yofufuza ndi kupanga zinthu, kapangidwe ka fomula, miyezo yowongolera khalidwe, komanso kupanga mwanzeru.
Kumbali inayi, imayankhanso mwachangu pempho la "chitsimikizo chobiriwira", imaona kuteteza chilengedwe ngati njira yofunika kwambiri yopititsira patsogolo kampaniyo, ndipo imatsogolera makampani pankhani ya miyezo ya zinthu zobiriwira. SIWAY yakhala ikutenga nawo mbali motsatizana popanga miyezo yoyenera monga muyezo wa dziko lonse wa GB/T 35609 "Zinthu Zobiriwira Zosalowa Madzi ndi Zotsekera" ndi muyezo wa gulu wa T/CECS 10029 "Kuwunika Zipangizo Zomangira Zobiriwira ndi Zotsekera Zomangira", kupereka mayankho athunthu a dongosolo lomatira lomatira losawononga chilengedwe kwa ogula onse omwe akufunafuna ubwino ndi kukongola.
Kodi mukumvetsa bwino za zomatira zobiriwira za silicone mutawona izi? Mukufunabe kudziwa zambiri za malonda, chonde ndikuyembekezera kukumana nanu mtsogolo.
SIWAY imateteza ogula onse ndi "Green",
Pitirizani, pitirirani, ndipo limbikitsani zabwino.
