Kukho iindlela zentengiso esiziqhelileyo kodwa abantu abaninzi banokugcinwa ebumnyameni.Umzekelo,
Kukho i-0 sucrose ekutyeni, kodwa ayithethi ukuba ayinaswekile,
Kukho amafutha e-0 ekutyeni, kodwa ayilingani neekhalori.
Ezinye iinkqubo zinokuthiwa kunzima ukuzigada ezifana nentsimi ye-silicone "green" sealant.Isitywina "esiluhlaza" sibhekisa kwi-eco-friendly sealant )
Ii-silicone sealants zisetyenzisiwe ekwakhiweni iminyaka emininzi, kwaye zihlala zisetyenziselwa ukutywinwa kunye nokudibanisa ekwakheni iindonga zamakhethini, iingcango kunye neefestile, ukudibanisa kunye nezinye iindawo.Ngokuhambela phambili kokuhlala ezidolophini, ii-silicone sealants ziye zangena kuzo zonke iindlela zobomi., Ukukhanyisa, izixhobo zendlu kunye nezinye izinto ezifihlakeleyo zidlala indima engenakulinganiswa.Okwangoku, i-silicone sealants isetyenziswa ngokubanzi kwaye isetyenziswa ngokubanzi, kwaye iimfuno zabathengi ze-silicone sealants azikhawulelwanga kwimisebenzi esisiseko yokudibanisa kunye nokutywinwa.Kwangaxeshanye, isenzo sekhabhoni esiphindwe kabini sikwabeke phambili iimfuno ezintsha zokukhutshwa okupheleleyo kwezakhiwo.Ngaphantsi kwe-superposition yezinto ezimbini, ii-silicone sealants eziluhlaza kunye nokusingqongileyo ziye zaba yinto entsha kwishishini.
Iimfuno ezintsha zikhuthaze iimarike ezintsha.Abathengi abaqhelekileyo bafanele bazikhethe njani izitywini ze-silicone "eziluhlaza"?
Namhlanje, sifumana impendulo kunye nawe!
1. Ziziphi iimeko eziza kuthathwa njenge-silicone sealant yangempela "eluhlaza"?
Ngaphambi kokuchaza iimveliso ze-sealant "eziluhlaza", kufuneka siqale siqonde ukuba yintoni imveliso "eluhlaza"?Ngokuqhelekileyo oko sikubiza ngokuthi "imveliso eluhlaza" kufuneka igwetywe kwiimpawu ezine zamandla, izibonelelo, indalo kunye nomgangatho ("Imithetho Jikelele yoVavanyo lweMveliso yeGreen" GB / T33761-2017).
Kwintsimi yee-sealants, iimpawu ezimbini zamandla kunye nezibonelelo zinempembelelo encinci ekusebenzeni okuluhlaza kwe-silicone sealants.Okusingqongileyo kunye nomgangatho ziye zaba zezona mpawu zibalulekileyo zokuvavanya ukuba i-silicone sealants "luhlaza".I-VOC ephantsi, ubutyhefu bomzimba obuphantsi, uMgangatho ophezulu (awunakwandiswa ngeoli) njalo njalo iwela kudidi lwayo zombini.
2. Uyichaza njani iVOC ephantsi?Ngowuphi umgangatho wamva nje kumda womxholo we-VOC?
Phakathi kwamacandelo amabini okusingqongileyo kunye nomgangatho, i-VOC ephantsi inokuthiwa yenye yezona mpawu ziqhelekileyo zokusingqongileyo kubathengi.Kwangoko ngo-2001, le migangatho yesizwe enyanzelekileyo yenze iimfuno ezicacileyo zomda wezinto ezinobungozi kwii-sealants zokuhombisa ngaphakathi-—
I-GB 18583 "IiMpahla zokuhombisa ngaPhakathi-Imida yezinto ezinobungozi kwiiNgxoxo"
I-GB 30982 "Imida yezinto ezinobungozi kwiiNgxoxo zoKwakha"
I-GB/T 33372 "Imida yeeNdibaniselwano ze-Volatile Organic kwi-Adhesives"
……
Ngomhla we-4 kaMatshi, i-2020, iKomiti yoLawulo lweMigangatho yeSizwe yakhupha umgangatho omtsha we-GB 33372-2020 "Imida ye-Volatile Organic Compounds kwi-Adhesives", eyahlula ngakumbi iimfuno zomda wokunamathela kwiinkalo ezahlukeneyo zesicelo.Kuhlobo olufanayo lokunamathelisa, amaxabiso ahlukeneyo omlinganiselo we-VOC womxholo aphinde ahlulwe ngokwemeko yangempela yeendawo ezahlukeneyo zesicelo.
▼Umda we-VOC womxholo wokuncamathelisa isambuku (GB 33372-2020)
3. Ukongeza kwi-VOC ephantsi, njani ukutolika ezinye iipropati kunye nokusebenza kwee-silicone sealants "eziluhlaza"?
01. Ubuthi obuphantsi bePhysiological
Okwangoku, i-silicone sealants ephakathi kwimarike inokwahlulwa ngokubanzi ibe luhlobo lotywala kunye nohlobo lwe-ketoxime sealants ngokwezinto ezincinci zeemolekyuli ezikhutshwe ngexesha lokunyanga.Ii-alcohol-type sealants, iimolekyuli ezincinci ezikhutshwe ngexesha lokunyanga zidla ngokuba ziimolekyuli ezincinci zotywala ezinje nge-methanol, i-ethanol (eyaziwa njenge-alcohol), kunye ne-ketoxime-type sealants, iimolekyuli ezincinci ezikhutshwa ngexesha lokunyanga zidla ngokuba zii-ketone oximes ezifana ne-butanone oxime. .
Uvavanyo oluguquguqukayo lwePhysiological Toxicity (Iisampulu zeZityalo)
Iintlobo ezimbini ze-sealants kunye nezityalo ezifanayo zafakwa kwindawo evaliweyo iintsuku ezili-10, kwaye impembelelo yeentlobo ezahlukeneyo ze-sealants ekukhuleni kwezityalo ezifanayo zaphandwa.Umahluko wokukhuselwa kwendalo phakathi kohlobo lotywala kunye nohlobo lwe-ketoxime ii-sealants zathelekiswa ne-biotoxicity.
Iziphumo zovavanyo zezi zilandelayo:
Izigqibo zokulinga zibonisa ukuba iimolekyuli ezincinci zotywala ezikhutshwe ngexesha lokunyangwa kwe-alcohol-based sealant azikho iziphumo ezibi ezicacileyo ekukhuleni kwezityalo, kwaye zihambelana nokusingqongileyo.
02. Umgangatho ophezulu we-sealant
Ukukhathazeka malunga nokukhuselwa kokusingqongileyo kunye nempilo yendawo yangaphakathi yezakhiwo,Siwayincoma kakhulu ukuba abasebenzisi bakhethe umgangatho ophezulu kunye neemveliso ze-sealant ezikumgangatho ophezulu, kwaye bagweme ukuthenga nokusebenzisa ezinye iimveliso eziphantsi kunye neziphantsi kwimarike, ezifana ne-oyile ezaliswe ngokutywinwa kwe-oyile emhlophe.Akunakuphela nje ukuba nokuqina okungahambi kakuhle, kuya kuguga, kuqhekeke, kunye ne-debond, kodwa ioli emhlophe ezaliswe kuyo iya kuqhubeka isasazeka kwaye iguquguquke, ibangele ukukhutshwa kwe-TVOC enkulu, echaphazela indawo yangaphakathi, kunye nokusebenza kokukhusela okusingqongileyo. ayinakuqinisekiswa.
4. Indlela yokukhetha uphawu lwe-"green" sealant?
Ngelizwi elinye:
Khetha nje u-SIWAY!
Njengophawu oluphambili kushishino lwe-sealant, i-SIWAY ibisoloko izibophelele kuphuhliso olukhuselekileyo, oluluhlaza, kunye noluzinzileyo olusempilweni.Kwelinye icala, iye yaziqhelanisa ngenene ingqikelelo yophuhliso lohlaza kuyo yonke inkqubo yophando lwemveliso kunye nophuhliso, uyilo lwefomula, imigangatho yolawulo lomgangatho, kunye nokuveliswa okukrelekrele.
Ngakolunye uhlangothi, iphinda iphendule ngenkuthalo kwikhwelo "yesatifikethi sohlaza", ithatha ukukhuselwa kokusingqongileyo okuluhlaza njengesicwangciso esibalulekileyo sophuhliso lwenkampani, kwaye ikhokelela kwishishini ngokwemigangatho yemveliso eluhlaza.I-SIWAY ithathe inxaxheba ngokulandelelana ekuqulunqweni kwemigangatho efanelekileyo efana nomgangatho wesizwe we-GB/T 35609 "iMveliso eluhlaza engangeni manzi kunye neMathiriyeli yokutywina" kunye nomgangatho weqela T/CECS 10029 "Uvandlakanyo lweMathiriyeli yeZakhiwo eziHlaza kunye neZitywina zoKwakha", ngokubonelela ngokusingqongileyo okubanzi. I-adhesive adhesive sealing system yezisombululo zokuncamathelisa kuye wonke umthengi osukela umgangatho kunye nobuhle.
Ngaba unokuqonda okunzulu kwee-silicone sealants eziluhlaza emva kokubona oku?Usafuna ukwazi ngakumbi imveliso inyaniso, nceda ujonge phambili ukudibana nawe kwixesha elizayo.
I-SIWAY ikhusela wonke umthengi nge "Green",
Zingisa, ugqithe, kwaye uxhobise okulungileyo.
