Pali njira zina zotsatsira malonda zomwe timazidziwa koma anthu ambiri amangosungidwa mumdima.Mwachitsanzo,
Pali 0 sucrose m'zakudya, koma sizitanthauza kuti mulibe shuga,
Pali mafuta 0 muzakudya, koma samafanana ndi ma calories.
Zochita zina zitha kunenedwa kukhala zovuta kuzipewa monga gawo la silicone "green" sealant.Chosindikizira "chobiriwira" chimatanthawuza za eco-friendly sealant )
Zosindikizira za silicone zakhala zikugwiritsidwa ntchito pomanga kwa zaka zambiri, ndipo nthawi zambiri zimagwiritsidwa ntchito kusindikiza ndi kugwirizanitsa pomanga makoma a nsalu, zitseko ndi mazenera, msonkhano ndi minda ina.Ndikupita patsogolo kwa mizinda, zosindikizira za silicone zalowa m'magulu onse amoyo., Kuunikira, zida zapakhomo ndi zina zobisika zimagwira ntchito yomwe sitingathe kuiwala.Pakadali pano, zosindikizira za silikoni zimagwiritsidwa ntchito mochulukirachulukira, ndipo zomwe ogula amafunikira pazosindikiza za silikoni sizimangogwira ntchito zomangira komanso zosindikiza.Pa nthawi yomweyo, ntchito yapawiri ya kaboni yaperekanso zofunikira zatsopano pakutulutsa kwathunthu kwanyumba.Pansi pazigawo ziwiri, zosindikizira za silicone zobiriwira komanso zachilengedwe zakhala njira yatsopano pamsika.
Zofuna zatsopano zalimbikitsa misika yatsopano.Kodi ogula wamba angasankhe bwanji zosindikizira zenizeni "zobiriwira" za silicone?
Lero, tikupeza yankho limodzi ndi inu!
1. Ndi mikhalidwe yotani yomwe iyenera kuonedwa ngati "green" silicone sealant?
Tisanafotokoze "zobiriwira" sealant mankhwala, choyamba tiyenera kumvetsa chimene "wobiriwira" mankhwala?Nthawi zambiri zomwe timatcha "zobiriwira" ziyenera kuyesedwa kuchokera kuzinthu zinayi za mphamvu, chuma, chilengedwe ndi khalidwe ("General Rules for Green Product Evaluation" GB/T33761-2017).
M'munda wa zosindikizira, zikhumbo ziwiri za mphamvu ndi zothandizira zimakhala ndi zotsatira zochepa pa ntchito yobiriwira ya silicone sealants.Chilengedwe ndi mtundu zakhala zikhalidwe ziwiri zofunika kwambiri pakuwunika ngati zosindikizira za silicone ndi "zobiriwira".Low VOC, otsika kawopsedwe thupi, mkulu Quality (osati mafuta-wowonjezera) ndi zina zotero kugwera m'gulu la onse.
2. Kodi kutanthauzira otsika VOC?Kodi mulingo waposachedwa kwambiri pa malire a VOC ndi chiyani?
Pakati pa zigawo ziwiri za chilengedwe ndi khalidwe, VOC yotsika ikhoza kunenedwa kuti ndi imodzi mwazodziwika bwino zachilengedwe kwa ogula.Pofika m'chaka cha 2001, mfundo zovomerezeka za dziko izi zakhala zikuwonetseratu zofunikira za malire a zinthu zovulaza mu zosindikizira zokongoletsa mkati-—
GB 18583 "Zida Zokongoletsera Mkati - Malire a Zinthu Zowopsa mu Zomatira"
GB 30982 "Malire a Zinthu Zowopsa mu Zomatira Zomanga"
GB/T 33372 "Malire a Zosakaniza Zachilengedwe Zosakhazikika mu Zomatira"
………
Pa Marichi 4, 2020, National Standardization Management Committee idapereka mulingo watsopano wa GB 33372-2020 "Malire a Volatile Organic Compounds in Adhesives", omwe adagawanso malire ofunikira pazomatira m'magawo osiyanasiyana ogwiritsira ntchito.Pamtundu womwewo wa zomatira, mitundu yosiyanasiyana ya malire a VOC imasiyanitsidwanso malinga ndi momwe zinthu zilili pamagawo osiyanasiyana ogwiritsira ntchito.
▼ Malire a VOC a zomatira zambiri (GB 33372-2020)
3. Kuphatikiza pa VOC yotsika, momwe mungatanthauzire zina zonse ndi magwiridwe antchito a "green" silicone sealants?
01. Kawopsedwe Wochepa Wathupi
Pakadali pano, zosindikizira zosalowerera ndale za silicone pamsika zimatha kugawidwa m'mitundu ya mowa ndi ketoxime zosindikizira kutengera tinthu tating'ono tating'ono timene timatulutsidwa pochiritsa.Zosindikizira zamtundu wa mowa, mamolekyu ang'onoang'ono omwe amatulutsidwa pochiritsa nthawi zambiri amakhala mamolekyu ang'onoang'ono a mowa monga methanol, ethanol (omwe amadziwika kuti mowa), ndi zosindikizira zamtundu wa ketoxime, mamolekyu ang'onoang'ono omwe amatulutsidwa pochiritsa nthawi zambiri amakhala ma ketone oximes monga butanone oxime molekyulu yaying'ono. .
Mayeso Osasinthika Kawopsedwe Kathupi (Zitsanzo za Zomera)
Mitundu iwiri ya zosindikizira ndi zomera zomwezo zinayikidwa pamalo otsekedwa kwa masiku 10, ndipo mphamvu ya mitundu yosiyanasiyana ya zosindikizira pa kukula kwa zomera zomwezo zinafufuzidwa.Kusiyana kwa chitetezo cha chilengedwe pakati pa mtundu wa mowa ndi ketoxime zosindikizira anafaniziridwa ndi biotoxicity.
Zotsatira zoyeserera ndi izi:
Zotsatira zoyesera zikuwonetsa kuti mamolekyu ang'onoang'ono a mowa omwe amatulutsidwa panthawi ya mankhwala a mowa-based sealant alibe zotsatira zoonekeratu pakukula kwa zomera, ndipo amakhala okonda zachilengedwe.
02. Sealant yapamwamba kwambiri
Kukhudzidwa ndi chitetezo cha chilengedwe komanso thanzi la m'nyumba zanyumba,Siwayamalimbikitsa mwamphamvu kuti ogwiritsa ntchito asankhe zosindikizira zapamwamba komanso zapamwamba kwambiri, ndikupewa kugula ndi kugwiritsa ntchito zinthu zotsika komanso zotsika pamsika, monga zosindikizira zodzaza mafuta zodzaza ndi mafuta oyera.Sikuti imakhala ndi kukhazikika kosakhazikika, imakalamba, imasweka, ndi debond, koma mafuta oyera odzazidwa mmenemo adzapitirizabe kufalikira ndi kuphulika, zomwe zimapangitsa kuti mpweya wambiri wa TVOC ukhale wochuluka, womwe umakhudza chilengedwe chamkati, ndi ntchito yoteteza chilengedwe. sizingatsimikizidwe.
4. Momwe mungasankhire chizindikiro cha "green" sealant?
M'mawu amodzi:
Ingosankha SIWAY!
Monga mtundu wotsogola pamakampani opanga zosindikizira, SIWAY yakhala ikudzipereka kuti ikhale yotetezeka, yobiriwira komanso yathanzi.Kumbali imodzi, idachitadi lingaliro lachitukuko chobiriwira munthawi yonse ya kafukufuku wazinthu ndi chitukuko, kapangidwe ka fomula, miyezo yoyendetsera bwino, komanso kupanga mwanzeru.
Kumbali inayi, imayankhanso mwachangu kuyitanidwa kwa "chitsimikizo chobiriwira", imatenga chitetezo chachilengedwe chobiriwira ngati njira yofunikira yachitukuko cha kampaniyo, ndikuwongolera makampaniwo malinga ndi miyezo yobiriwira.SIWAY yatenga nawo gawo motsatizana pakuphatikiza miyezo yoyenera monga muyezo wadziko lonse wa GB/T 35609 "Green Product Waterproof and Sealing Materials" ndi gulu lokhazikika la T/CECS 10029 "Kuwunika kwa Zida Zomangira Zobiriwira ndi Zosindikiza Zomanga", popereka chilengedwe chonse. ochezeka zomatira kusindikiza dongosolo zomatira mayankho kwa wogula aliyense amene amatsata khalidwe ndi kukongola.
Kodi mumamvetsetsa mozama za zosindikizira zobiriwira za silicone mutawona izi?Mukufunabe kudziwa zambiri zowona zamalonda, chonde yembekezerani kukumana nanu mtsogolo.
SIWAY imateteza wogula aliyense ndi "Green",
Limbikirani, pitirirani, ndi kupatsa mphamvu zabwino.
