Kukho iindlela ezithile zokuthengisa esizaziyo kodwa abantu abaninzi basenokungazazi. Umzekelo,
Akukho sucrose ekutyeni, kodwa oko akuthethi ukuba ayinaswekile,
Akukho mafutha ekutyeni, kodwa alingani neekhalori.
Ezinye iindlela zesiqhelo kunokuthiwa kunzima ukuziphepha ezifana nentsimi ye-silicone "green" sealant.Isitywini “esiluhlaza” sibhekisa kwisitywini esinobuhlobo nokusingqongileyo )
Ii-silicone sealants bezisetyenziswa ekwakheni iminyaka emininzi, kwaye zihlala zisetyenziselwa ukuvala nokubopha ekwakheni iindonga zamakhethini, iingcango kunye neefestile, indibano kunye nezinye iindawo. Ngokuhambela phambili kwesixeko, ii-silicone sealants ziye zangena kuzo zonke iinkalo zobomi. , Izibane, izixhobo zasekhaya kunye nezinye izinto ezingabonakaliyo zidlala indima engenakuthathwa njengento engaphantsi. Okwangoku, ii-silicone sealants zisetyenziswa kakhulu, kwaye iimfuno zabathengi zee-silicone sealants azikhawulelwanga kwimisebenzi esisiseko yokubopha nokuvala. Kwangaxeshanye, isenzo se-double carbon sikwabeke phambili iimfuno ezintsha zokukhupha umbane kwizakhiwo. Phantsi kokubekwa kwezinto ezimbini, ii-silicone sealants eziluhlaza nezinobuhlobo nokusingqongileyo ziye zaba yindlela entsha kushishino.
Iimfuno ezintsha zikhuthaze iimarike ezintsha. Abathengi abaqhelekileyo bangazikhetha njani izitywina ze-silicone "eziluhlaza" zokwenyani?
Namhlanje, sifumana impendulo kunye nawe!
1. Ziziphi iimeko ekufuneka zithathwe njenge-silicone sealant "eluhlaza" yokwenyani?
Ngaphambi kokuba sichaze iimveliso "eziluhlaza" ezitywinayo, kufuneka siqale siqonde ukuba yintoni imveliso "eluhlaza"? Ngokwesiqhelo oko sikubiza ngokuba ziimveliso "eziluhlaza" kufuneka kugwetywe ngokweempawu ezine zamandla, izixhobo, okusingqongileyo kunye nomgangatho ( "Imithetho Jikelele yoVavanyo lweMveliso oluLuhlaza" GB/T33761-2017).
Kwicandelo lezinto zokutywina, ezi mpawu zimbini zamandla kunye nezixhobo azinampembelelo ingako ekusebenzeni okuluhlaza kwezinto zokutywina ze-silicone. Indalo kunye nomgangatho ziye zaba zezona mpawu zimbini zibalulekileyo zokuvavanya ukuba izinto zokutywina ze-silicone "ziluhlaza" na. I-VOC ephantsi, ubuthi obuphantsi bomzimba, Umgangatho ophezulu (ayiyo i-oyile eyandisiweyo) njalo njalo ziwela kudidi lwazo zombini.
2. Ungayichaza njani i-VOC ephantsi? Ngowuphi umgangatho wamva nje womda womxholo we-VOC?
Phakathi kwezinto ezimbini ezikwimeko-bume kunye nomgangatho, i-VOC ephantsi inokuthiwa yenye yezona zinto ziqhelekileyo kubathengi. Kwangoko ngo-2001, le migangatho yesizwe inyanzelisayo iye yacacisa iimfuno zomda wezinto ezinobungozi kwizitywina zokuhombisa ngaphakathi——
I-GB 18583 "Izinto zokuhombisa zangaphakathi - Imida yezinto eziyingozi kwi-Adhesives"
I-GB 30982 "Imida yezinto eziyingozi kwiZincamathelisi zokwakha"
GB/T 33372 "Imida yeeKhompawundi ze-Organic eziguquguqukayo kwii-Adhesives"
……
Ngomhla wesi-4 kweyoKwindla, ngowama-2020, iKomiti yoLawulo lweMigangatho yeSizwe ikhuphe i-GB 33372-2020 standard entsha ethi "Imida yeeCompounds ze-Volatile Organic kwi-Adhesives", eyahlulahlula iimfuno zomda we-adhesives kwiindawo ezahlukeneyo zokusetyenziswa. Kuhlobo olufanayo lwe-adhesive, amaxabiso ahlukeneyo omda womxholo we-VOC nawo ayahlulwa ngokwemeko yokwenyani yeendawo ezahlukeneyo zokusetyenziswa.
▼Umda womxholo we-VOC wezinto zokuncamathelisa ngobuninzi (GB 33372-2020)
3. Ukongeza kwi-VOC ephantsi, ungatolika njani ezinye iipropati kunye nokusebenza kwe-silicone sealants "eluhlaza"?
01. Ubuthi obuphantsi bomzimba
Okwangoku, ii-sealants ze-silicone ezingathathi hlangothi ezithengiswayo zingahlulwahlulwa zibe zii-sealants zohlobo lotywala kunye nee-sealants zohlobo lwe-ketoxime ngokwezinto ezincinci ze-molecular ezikhutshwa ngexesha lokunyanga. Ii-sealants zohlobo lotywala, ii-molecules ezincinci ezikhutshwa ngexesha lokunyanga zihlala zii-molecules ezincinci zotywala ezifana ne-methanol, i-ethanol (eyaziwa ngokuba yi-alcohol), kunye nee-sealants zohlobo lwe-ketoxime, ii-molecules ezincinci ezikhutshwa ngexesha lokunyanga zihlala zii-ketone oximes ezifana ne-butanone oxime I-molecule encinci.
Uvavanyo lweTyhefu yePhysiological eguquguqukayo (Iisampulu zeZityalo)
Iintlobo ezimbini zezitywini kunye nezityalo ezifanayo zabekwa kwindawo evaliweyo kangangeentsuku ezili-10, kwaye impembelelo yeentlobo ezahlukeneyo zezitywini ekukhuleni kwezityalo ezifanayo yaphandwa. Umahluko ekukhuselweni kwendalo phakathi kwezitywini zohlobo lotywala kunye ne-ketoxime uthelekiswe yi-biotoxicity.
Iziphumo zovavanyo zezi zilandelayo:
Izigqibo zovavanyo zibonisa ukuba iimolekyuli ezincinci zotywala ezikhutshwa ngexesha lenkqubo yokunyanga i-sealant esekelwe kutywala azinazo iziphumo ezibi ezibonakalayo ekukhuleni kwezityalo, kwaye zinobuhlobo ngakumbi nokusingqongileyo.
02. Isitywini esisemgangathweni ophezulu
Ixhalabile ngokhuseleko lokusingqongileyo kunye nempilo yendalo engaphakathi yezakhiwo,ISiwayicebisa kakhulu ukuba abasebenzisi bakhethe iimveliso zesitywini ezisemgangathweni ophezulu nezikumgangatho ophezulu, kwaye baphephe ukuthenga nokusebenzisa ezinye iimveliso ezikumgangatho ophantsi neziphantsi ezithengiswayo, ezifana nezitywini ezizaliswe yioyile ezizaliswe yi-oyile emhlophe. Ayipheleli nje ekubeni ingabi namandla, iya kuguga, iqhekeke, kwaye ikhuphe ibhondi, kodwa ioyile emhlophe ezaliswe kuyo iya kuqhubeka isasazeka kwaye iguquguquka, ibangele inani elikhulu lokukhutshwa kweTVOC, okuchaphazela imeko-bume yangaphakathi, kwaye ukusebenza kokhuseleko lokusingqongileyo akunakuqinisekiswa.
4. Ungayikhetha njani uphawu lwe-sealant "eluhlaza"?
Ngelizwi elinye:
Khetha nje i-SIWAY!
Njengophawu oluphambili kushishino lwe-sealant, i-SIWAY ibisoloko izibophelele kuphuhliso olukhuselekileyo, oluluhlaza, nolusempilweni. Kwelinye icala, iye yasebenzisa ngokwenene ingcamango yophuhliso oluluhlaza kuyo yonke inkqubo yophando nophuhliso lwemveliso, uyilo lwefomula, imigangatho yolawulo lomgangatho, kunye nokuveliswa ngobuchule.
Kwelinye icala, ikwasabela ngokukhutheleyo kwisicelo "sesiqinisekiso esiluhlaza", ithatha ukhuseleko lokusingqongileyo oluluhlaza njengecebo elibalulekileyo lophuhliso lwenkampani, kwaye ikhokela ishishini ngokwemigangatho yemveliso eluhlaza. I-SIWAY ithathe inxaxheba ngokulandelelana ekuqulunqweni kwemigangatho efanelekileyo efana nomgangatho wesizwe we-GB/T 35609 "Imveliso Eluhlaza Engangeni Manzi Nezinto Zokuvala" kunye nomgangatho weqela we-T/CECS 10029 "Uvavanyo lweZixhobo Zokwakha Eziluhlaza kunye Nezitywino Zokwakha", ibonelela ngezisombululo ezibanzi zenkqubo yokuncamathelisa yokutywina enobuhlobo nokusingqongileyo kumthengi ngamnye ofuna umgangatho nobuhle.
Ngaba unokuqonda okunzulu ngee-sealants ze-silicone eziluhlaza emva kokubona oku? Usafuna ukwazi okungakumbi ngenyaniso yemveliso, nceda ujonge phambili ekudibana nawe kwixesha elizayo.
I-SIWAY ikhusela wonke umthengi nge-"Green",
Phikelela, udlule, kwaye unike amandla okulungileyo.
