Kuneminye imikhuba yokukhangisa esiyaziyo kodwa abantu abaningi bangase bagcinwe bengazi lutho. Isibonelo,
Kukhona i-sucrose engu-0 ekudleni, kodwa akusho ukuthi ayinashukela,
Kukhona amafutha angu-0 ekudleni, kodwa awalingani nama-calories.
Eminye imikhuba kungashiwo ukuthi kunzima ukuyigwema njengensimu ye-silicone “green” sealant.Isivali “esiluhlaza” sibhekisela kusivali esinobungani nemvelo )
Ama-sealant e-silicone asetshenziswe ekwakheni iminyaka eminingi, futhi avame ukusetshenziselwa ukuvala nokubopha ekwakheni izindonga zamakhethini, iminyango namafasitela, ukuhlanganisa kanye neminye imikhakha. Ngokuthuthuka kwentuthuko yedolobha, ama-sealant e-silicone angene kuzo zonke izindlela zokuphila. , Ukukhanyisa, izinto zasendlini kanye nezinye izinto ezicashile zidlala indima engenakubhekwa phansi. Njengamanje, ama-sealant e-silicone asetshenziswa kabanzi, futhi izidingo zabathengi zama-sealant e-silicone azikhawulelwe emisebenzini eyisisekelo yokubopha nokuvala. Ngesikhathi esifanayo, isenzo se-double carbon siphinde sabeka phambili izidingo ezintsha zokukhishwa okuphelele kwezakhiwo. Ngaphansi kokufakwa kwezinto ezimbili, ama-sealant e-silicone aluhlaza futhi anobungani nemvelo asephenduke umkhuba omusha embonini.
Izidingo ezintsha zikhuthaze izimakethe ezintsha. Abathengi abavamile kufanele bazikhethe kanjani izithiyo ze-silicone "eziluhlaza" zangempela?
Namuhla, sithola impendulo kanye nawe!
1. Yiziphi izimo okufanele zibhekwe njenge-silicone sealant yangempela “eluhlaza”?
Ngaphambi kokuchaza imikhiqizo "eluhlaza" yokuvala, kumele siqale siqonde ukuthi uyini umkhiqizo "oluhlaza"? Ngokuvamile lokho esikubiza ngokuthi imikhiqizo "eluhlaza" kudingeka kwahlulelwe ngezimfanelo ezine zamandla, izinsiza, imvelo kanye nekhwalithi ( "Imithetho Ejwayelekile Yokuhlolwa Komkhiqizo Oluhlaza" GB/T33761-2017).
Emkhakheni wezinto zokuvala, lezi zimfanelo ezimbili zamandla nezinsiza azinawo umthelela omkhulu ekusebenzeni okuluhlaza kwezinto zokuvala ze-silicone. Indawo kanye nekhwalithi kube yizimfanelo ezimbili ezibaluleke kakhulu zokuhlola ukuthi izinto zokuvala ze-silicone "ziluhlaza" yini. I-VOC ephansi, ubuthi obuphansi bomzimba, Ikhwalithi ephezulu (hhayi enwetshiwe ngamafutha) nokunye kuwela esigabeni sazo zombili.
2. Ungayichaza kanjani i-VOC ephansi? Iyini indinganiso yakamuva yomkhawulo wokuqukethwe kwe-VOC?
Phakathi kwezingxenye ezimbili zemvelo nekhwalithi, i-VOC ephansi ingathiwa ingenye yezimfanelo zemvelo ezijwayelekile kakhulu kubathengi. Kusukela ngo-2001, lezi zindinganiso zikazwelonke eziphoqelekile ziye zacacisa izidingo zomkhawulo wezinto eziyingozi kuma-sealant okuhlobisa ingaphakathi——
I-GB 18583 "Izinto Zokuhlobisa Zangaphakathi - Imikhawulo Yezinto Eziyingozi Ezinamathelisweni"
I-GB 30982 "Imikhawulo Yezinto Eziyingozi Ezinamathelisweni Zokwakha"
I-GB/T 33372 "Imikhawulo Yamakhemikhali E-Organic Aguquguqukayo Kuma-Adhesive"
……
NgoMashi 4, 2020, iKomidi Lokuphathwa Kokuqiniswa Kukazwelonke lakhipha i-GB 33372-2020 standard entsha ethi "Imikhawulo Yama-Volatile Organic Compounds in Adhesives", eyahlukanisa futhi izidingo zomkhawulo wama-adhesives emikhakheni ehlukahlukene yesicelo. Ohlotsheni olufanayo lwe-adhesive, amanani ahlukene omkhawulo wokuqukethwe kwe-VOC nawo ahlukaniswa ngokwesimo sangempela samasimu ehlukene esicelo.
▼Umkhawulo wokuqukethwe kwe-VOC kwezinamathelisi eziningi (GB 33372-2020)
3. Ngaphezu kwe-VOC ephansi, ungahumusha kanjani ezinye izakhiwo kanye nokusebenza kwama-sealant e-silicone “aluhlaza”?
01. Ubuthi Obuphansi Bemvelo
Njengamanje, ama-sealant e-silicone angathathi hlangothi emakethe angahlukaniswa ngokujwayelekile abe ama-sealant ohlobo lotshwala kanye nama-sealant ohlobo lwe-ketoxime ngokuya ngezinto ezincane zama-molecule ezikhishwa ngesikhathi sokwelapha. Ama-sealant ohlobo lotshwala, ama-molecule amancane akhishwa ngesikhathi sokwelapha ngokuvamile angama-molecule amancane otshwala njenge-methanol, i-ethanol (eyaziwa kakhulu ngokuthi utshwala), kanye nama-sealant ohlobo lwe-ketoxime, ama-molecule amancane akhishwa ngesikhathi sokwelapha ngokuvamile angama-ketone oximes njenge-butanone oxime. I-molecule encane.
Ukuhlolwa Kobuthi Bemvelo Obuguquguqukayo (Amasampula Ezitshalo)
Izinhlobo ezimbili zezivalo kanye nezitshalo ezifanayo zafakwa endaweni evaliwe izinsuku eziyi-10, futhi kwahlolwa ithonya lezinhlobo ezahlukene zezivalo ekukhuleni kwezitshalo ezifanayo. Umehluko ekuvikelweni kwemvelo phakathi kwezivalo zohlobo lotshwala kanye ne-ketoxime waqhathaniswa nobuthi bezinto eziphilayo.
Imiphumela yokuhlola imi kanje:
Iziphetho zokuhlola zibonisa ukuthi ama-molecule amancane otshwala akhishwa ngesikhathi senqubo yokwelapha i-sealant esekelwe kutshwala awanazo imiphumela emibi esobala ekukhuleni kwezitshalo, futhi anobungani kakhulu nemvelo.
02. Isivali sekhwalithi ephezulu
Bekhathazekile ngokuvikelwa kwemvelo kanye nempilo yendawo yangaphakathi yezakhiwo,ISiwayincoma kakhulu ukuthi abasebenzisi bakhethe imikhiqizo ye-sealant esezingeni eliphezulu nekhwalithi ephezulu, futhi bagweme ukuthenga nokusebenzisa eminye imikhiqizo ephansi nephansi emakethe, njenge-sealants egcwele uwoyela egcwaliswe nge-sealant yamafutha amhlophe. Ayigcini nje ngokuba nokuqina okungekuhle, izoguga, iqhekeke, futhi ihlukane, kodwa uwoyela omhlophe ogcwaliswe kuyo uzoqhubeka nokusabalalisa nokuguquguquka, okubangela inani elikhulu lokukhishwa kwe-TVOC, okuthinta indawo yangaphakathi, futhi ukusebenza kokuvikelwa kwemvelo akunakuqinisekiswa.
4. Ungayikhetha kanjani uhlobo lwe-sealant “eluhlaza”?
Ngelilodwa nje:
Khetha nje i-SIWAY!
Njengomkhiqizo ohamba phambili embonini ye-sealant, i-SIWAY ibilokhu izibophezele ekuthuthukisweni okuphephile, okuluhlaza, nokunempilo okusimeme. Ngakolunye uhlangothi, iye yasebenzisa ngempela umqondo wokuthuthukiswa okuluhlaza kuyo yonke inqubo yocwaningo lomkhiqizo kanye nokuthuthukiswa kwawo, ukwakheka kwefomula, amazinga okulawula ikhwalithi, kanye nokukhiqiza okuhlakaniphile.
Ngakolunye uhlangothi, isabela ngenkuthalo esicelweni "sesitifiketi esiluhlaza", ithatha ukuvikelwa kwemvelo okuluhlaza njengesu elibalulekile lokuthuthukiswa kwenkampani, futhi ihola imboni ngokwezindinganiso zomkhiqizo oluhlaza. I-SIWAY ihlanganyele ngokulandelana ekuhlanganisweni kwezindinganiso ezifanele njenge-GB/T 35609 standard "Green Product Waterproof and Sealing Materials" kanye ne-T/CECS 10029 standard "Evaluation of Green Building Materials and Construction Sealants", enikeza izixazululo eziphelele zokunamathela zesistimu yokunamathela enobungani nemvelo kuwo wonke umthengi ophishekela ikhwalithi nobuhle.
Ingabe unokuqonda okujulile ngama-sealant aluhlaza e-silicone ngemva kokubona lokhu? Usafuna ukwazi iqiniso lomkhiqizo ongeziwe, sicela ubheke phambili ekuhlanganeni nawe esikhathini esizayo.
I-SIWAY ivikela wonke umthengi nge-“Green”,
Phikelela, udlule, futhi unike amandla okuhle.
